Why This Gluten-Free Vegan Green Bean Casserole Will Become Your New Holiday Favorite
This year marks a truly special occasion for our family: after what feels like an eternity of missing out, we will finally have a green bean casserole on our holiday table again! For countless holidays, this beloved dish was absent due to severe food allergies within our family. I honestly thought it was an impossible feat to create a green bean casserole that was both gluten-free and dairy-free yet still possessed that luxurious, creamy, and dreamy texture we all crave. I envisioned a compromise, a watered-down version, but I was so delightfully mistaken!
This recipe isn’t just a substitute; it’s a revelation. It stands proudly as a testament to the fact that allergy-friendly food can be incredibly delicious and utterly satisfying. The heart of this magnificent casserole lies in its exquisitely creamy sauce, which draws inspiration from a sophisticated French mustard sauce, famously championed by the culinary icon, Ina Garten. When you hear “Ina Garten,” you know it’s going to be something truly special, and this sauce lives up to that reputation with flying colors.
Achieving such a profoundly flavorful sauce requires a combination of thoughtful techniques and, crucially, a couple of my secret ingredients. We start by building a robust flavor base with perfectly caramelized onions and deeply browned mushrooms. These elements contribute layers of umami and sweetness that are essential. Then, we deglaze the pan with dry white wine, capturing all those delectable browned bits and infusing the sauce with even more complexity. But the true magic happens with the inclusion of **my two secret weapons: both Dijon mustard and stone-ground mustard.**
You might be surprised to find mustard in a green bean casserole recipe, and I’ve yet to encounter another recipe that uses it quite like this. However, these mustards don’t make the casserole taste overtly “mustardy.” Instead, they impart an unparalleled depth, a subtle tang, and a certain je ne sais quoi that brightens the entire dish and makes the vegetables sing. This unique flavor profile ensures your green bean casserole will stand head and shoulders above any bland, run-of-the-mill versions you’ve had in the past. It’s truly a game-changer!
And for those of you with picky eaters or personal aversions to mushrooms or onions – don’t worry! I’ve developed a clever trick within the recipe instructions that allows you to capture all that amazing flavor without a single visible piece of mushroom or onion in the final dish. So, keep reading; you won’t want to miss this ingenious solution!
Demystifying the Gluten-Free Aspect of This Green Bean Casserole
The necessity for a gluten-free dish is paramount in our household; my son has a severe wheat allergy, and my husband manages a gluten intolerance. Therefore, every dish we prepare absolutely *has* to be gluten-free. For a long time, my biggest concern with developing an allergy-friendly green bean casserole was the absence of that iconic, crunchy fried onion topping. It’s such a classic element, and I worried the dish wouldn’t feel complete without it.
However, once I perfected this incredibly rich and flavorful sauce, my worries completely dissipated. The sauce itself is so outstanding, so deeply satisfying, that I genuinely believe the casserole is perfectly wonderful without a traditional fried onion topping. By foregoing that specific element, nearly all the other ingredients in this recipe are naturally gluten-free on their own. We’re talking fresh green beans, delicious mushrooms, savory onions, and a creamy, dairy-free base. So, we can confidently say “bye bye gluten!” without sacrificing any flavor or texture.
If your dietary needs are less strict, perhaps you only need the casserole to be dairy-free but can still consume gluten. In that case, you have the flexibility to use any store-bought French fried onions you prefer on top. Just be sure to double-check labels if cross-contamination is a concern for other family members or guests. This flexibility ensures that the recipe can adapt to various dietary requirements while still delivering a delicious result.
Craving a Topping? Gluten-Free Topping Options for Your Green Bean Casserole
As you can see from the beautiful images, I personally opted for a topping-free presentation in my photos. The truth is, I live in a charming small town, and despite my best efforts and diligent searching, I simply couldn’t track down gluten-free French fried onions locally. If I had been able to exercise a bit more patience and wait for a delivery, you can certainly find fantastic Sprout’s Gluten Free French Fried Onions available for purchase on Amazon. But with Thanksgiving menu planning looming, I was absolutely determined to get this incredible recipe out to all of you as quickly as possible!
However, if you’re in a similar situation and can’t find pre-made gluten-free fried onions, or if you simply prefer a homemade touch, there are fantastic alternatives to create a satisfying crunch. You could easily create a homemade panko-style crust using crushed-up rice Chex cereal, which adds a lovely crisp texture. Another wonderfully simple and delicious option is to gently crush potato chips and sprinkle them on top. The saltiness and crunch of potato chips can be a surprisingly delightful addition, adding an extra layer of flavor and texture that perfectly complements the creamy green beans. For an even more gourmet touch, consider making your own crispy fried shallots from scratch. Simply thinly slice shallots, toss them in a little gluten-free flour (or cornstarch for extra crispness), and fry them until golden brown. These homemade crispy bits are utterly divine and elevate the casserole to an even higher level of sophistication!
The Genius “Mom Hack”: What if You Don’t Like Mushrooms or Onions?
Want to know a little secret? My own kids, bless their hearts, are not fans of mushrooms or onions. Yet, surprisingly, they eat this casserole without a single complaint! This is where my ultimate **mom hack** comes into play, and it’s a total game-changer for parents or anyone cooking for picky eaters. Here’s how to do it: absolutely go ahead and caramelize those onions and perfectly brown those mushrooms.
Do NOT skip this crucial step! The process of caramelizing and browning is essential because it unlocks an incredible depth of savory, umami flavor that forms the very backbone of this sauce. It transforms bland vegetables into rich, intensely flavorful components. But here’s the trick: once the sauce is completely finished and simmering, and before you stir in your blanched green beans, carefully transfer the entire sauce (along with the caramelized onions and browned mushrooms) into a high-quality blender. A powerful blender, like a Blendtec or Vitamix, is ideal here, as it will effortlessly blend everything until it’s ultra-smooth and velvety.
The result? A sauce that retains every ounce of that amazing, complex flavor from the onions and mushrooms, but without any of the texture. No chunky bits, no visible slices, just pure, unadulterated deliciousness. The sauce will be wonderfully smooth, creamy, and nobody will be any the wiser about its secret ingredients. You won’t have to endure any whining or complaining about mushrooms and onions. This is truly a **WINNING!** strategy that keeps everyone happy and well-fed, and ensures your dish is packed with maximum flavor. It’s the perfect solution for even the most discerning palates!
Crafting a Delicious Vegan Green Bean Casserole
This green bean casserole proudly stands as a fully vegan dish, meticulously crafted to be free from all animal products without compromising on taste or texture. The key to its vegan nature begins with how we sauté our aromatic vegetables. Instead of traditional butter, which contains dairy, we opt for high-quality olive oil. Olive oil provides a wonderful base for caramelizing the onions and browning the mushrooms, imparting its own subtle, fruity notes while remaining completely plant-based.
The true secret to achieving that coveted creaminess without dairy lies in our choice of a plant-based cream cheese. I personally favor and recommend soy-based cream cheeses for their rich texture and neutral flavor profile, which blends seamlessly into the sauce. Brands like Tofutti or Go Veggie are excellent choices that deliver exceptional results. Because we rely on olive oil and these fantastic dairy-free alternatives, our recipe contains no dairy, no eggs, and absolutely no meat products, making it a perfect fit for a vegan lifestyle.
While our family needs to avoid nuts, I’m confident that nut-based cream cheeses, such as Kite Hill (made from almonds), would also perform beautifully in this recipe if nuts are part of your diet. Their creamy consistency is very similar to dairy cream cheese, making them an ideal substitute. If you happen to find Tofutti sour cream but not their cream cheese, don’t fret! Sour cream can also work wonderfully, lending a similar tang and creaminess to the sauce, ensuring your casserole is still incredibly delicious and perfectly vegan.
Navigating Allergies: What if You Can’t Have Soy in Your Green Bean Casserole?
I understand that navigating food allergies can be complex, and for some, soy is also a concern. If you need this casserole to be truly free of the top 8 common allergens, and cannot consume soy as my original recipe typically calls for, rest assured, there’s an easy and delicious swap! Simply replace the soy-based cream cheese with a coconut-based cream cheese alternative. Brands like Daiya offer excellent coconut-based options that are widely available.
It’s important to clarify that despite its name, coconut is botanically classified as a fruit, not a tree nut. This distinction means that coconut-based products are generally considered safe for individuals with tree nut allergies, allowing this casserole to remain top-8-free and inclusive for an even broader range of dietary needs. The coconut cream cheese will still provide that rich, creamy texture and a subtle, pleasant flavor that complements the green beans and savory sauce beautifully, ensuring everyone can enjoy this delightful side dish without worry.

Gluten Free Vegan Green Bean Casserole

For years we went without green bean casserole, thinking it couldn’t be made gluten and dairy free. Now we know better! This creamy vegetable side dish is loaded with flavor thanks to two secret ingredients. Enjoy this Gluten Free Vegan Green Bean Casserole for Thanksgiving or any time you want to punch up your side dishes!
Ingredients
- 1 pound fresh green beans, washed & trimmed
- 2 Tablespoons olive oil
- 1 cup halved and thinly sliced yellow onions (approx. 1 onion)
- 8 oz halved white button mushrooms
- 2 Tablespoons dry white wine
- 9 ounces dairy free cream cheese (see post above for options)
- 1 clove garlic (1/2 tsp minced)
- 1 Tablespoon Dijon mustard
- 1 teaspoon whole-grain mustard
- 1 tsp dried parsley
- S&P to taste
- 1/2 cup broth (if you only need it dairy free, then do beef, that will give the richest flavor. If you need it to be vegan, use vegetable.)
- OPTIONAL: Gluten free French Fried Onions
Instructions
1. Preheat oven to 350 degrees F.
2. Bring a large pot of water to a rolling boil.
3. While the water is heating up, thoroughly wash and trim the ends off your fresh green beans.
4. Carefully place the prepared green beans into the boiling water and cook for approximately six minutes, or until they become bright green and are crisp-tender. Avoid overcooking to maintain their vibrant color and slight bite.
5. While the green beans are cooking, prepare a large bowl filled with ice water. Once the green beans have reached the desired doneness, immediately transfer them from the boiling water to the ice bath using a slotted spoon or spider. This “shocking” process halts the cooking and preserves their beautiful green color. Once completely cooled, drain them well and transfer them to a large mixing bowl.
6. Over medium heat, place an oven-safe skillet. Add the two tablespoons of olive oil. Add the thinly sliced yellow onion and cook, stirring occasionally, until the onions are tender and translucent, about 5-7 minutes.
7. Add the halved white button mushrooms to the skillet with the onions and season generously with salt and pepper. Continue to cook, stirring frequently, until the mushrooms are beautifully golden brown and the onions are deeply caramelized, adding rich flavor to the base of your sauce.
8. Add the cooked mushroom and onion mixture to the mixing bowl with the green beans. Toss gently to combine, then set aside. (Important Note for Picky Eaters: If you prefer not to have visible onions and mushrooms in the final dish, do NOT mix them with the green beans at this stage. Instead, set the cooked onions and mushrooms aside to blend them directly into the sauce later. Refer to the “Mom Hack” section in the post above for detailed instructions!)
9. Now it’s time to create our incredibly flavorful sauce! Return the skillet to medium heat. Add the dry white wine to the pan, and using a wooden spoon, scrape up any browned bits that are stuck to the bottom of the pan – these are packed with flavor! Next, add the minced garlic and cook until it becomes fragrant, which typically takes about 1 minute. Then, stir in both the Dijon mustard and the whole-grain mustard, along with the dairy-free cream cheese and dried parsley. Gradually add the broth, stirring continuously until the sauce is smooth and creamy. Taste the sauce and adjust the salt and pepper as needed to your preference. Once seasoned, turn off the heat.
10. If you separated the onions and mushrooms, now is the time to blend them into the sauce using a high-powered blender until completely smooth. Once blended, return the sauce to the skillet. Add the mixed green bean, onion, and mushroom mixture (or just the green beans if you blended the aromatics) to the pan and gently coat everything in the luxurious sauce.
11. Stir the casserole gently over low heat until everything is thoroughly heated through and beautifully combined. If you prefer a slightly thinner, more pourable sauce, feel free to add an additional splash of broth until it reaches your desired consistency.
12. (Optional Topping) If you managed to find or prepare gluten-free French fried onions, you can sprinkle them over the casserole and bake for the last 5 minutes of cooking time to heat them through and make them crispy. (As noted in the post above, finding them can be a challenge, especially in smaller towns, so feel free to omit or use a homemade topping!)
13. Serve your delightful Gluten-Free Vegan Green Bean Casserole warm and enjoy! Any cooled leftovers can be stored in an airtight container in the refrigerator for 2-3 days, making it excellent for holiday meal prep or a delicious weeknight side. This casserole is perfect for Thanksgiving, Christmas, or any Sunday dinner where you want a comforting and inclusive side dish.
*To save time and make this dish faster, you can substitute two cans of well-drained green beans (ensure no added salt if possible) instead of using fresh green beans and blanching them. This will significantly cut down on prep time.
**UPDATED TO ADD: Previously, this recipe did not include broth in the sauce, but I’ve updated it to incorporate a half cup of broth. This addition makes the sauce even creamier and more luxurious. If you are making this recipe only to be dairy-free (not strictly vegan), beef stock can be used for an exceptionally rich and deep flavor. For a completely vegan version, vegetable broth is the ideal choice.

Picky Eater Hack Recap: If you or your guests prefer not to have visible onions and mushrooms in the final dish, follow these simple steps:
1. Once the onions have caramelized and the mushrooms have browned (step 7 in instructions), set them aside in a separate bowl. Do not mix them with the green beans.
2. Continue making the sauce as directed in step 9.
3. Once you’ve made the sauce in the skillet, carefully scrape the entire sauce mixture into a high-speed blender (like a Blendtec or Vitamix). Add the reserved caramelized onions and browned mushrooms to the blender with the sauce.
4. Blend until the sauce is completely smooth and creamy, with no visible pieces of onion or mushroom remaining. This ensures all the incredible flavor is incorporated without any texture objections.
5. Pour the blended, smooth sauce back into your oven-safe skillet, then toss in your blanched green beans (from step 5). Proceed with the rest of the recipe as instructed from step 10 onwards.
Make Ahead Tip: You can prepare the green beans and the sauce (without combining) a day in advance. Store them separately in airtight containers in the refrigerator. On the day of serving, gently reheat the sauce, add the green beans, and finish in the oven as directed.
Ingredient Variations: Feel free to experiment with different types of dairy-free cream cheese based on availability and your specific allergy needs. As mentioned, coconut-based alternatives work wonderfully for soy allergies.
