Casseroles are genuinely one of the easiest ways to feed a table of mixed eaters at Thanksgiving. They travel well, reheat without fuss, and you can assemble most of them the night before. This list covers ten vegan casseroles that actually belong on a holiday table, ranging from a Greek-style green bean bake to a buffalo cauliflower dish that will surprise anyone who thinks vegan food plays it safe.
I put this together for people who want something more substantial than a roasted vegetable tray but don’t want to spend the whole day in the kitchen. Every recipe here is fully plant-based. Most are also gluten-free or have a straightforward gluten-free swap. A few work just as well for a regular Tuesday dinner as they do for a holiday, which I consider a bonus, not a problem.

How I Picked These
I looked for recipes where the casserole format actually does something useful: it concentrates flavour, creates a crisp top, or makes the dish easier to serve to a crowd than a stovetop version would. I skipped anything that was just a bowl of roasted vegetables poured into a baking dish. Every recipe here has a distinct sauce, topping, or layering method that justifies baking it. I also checked that the ingredient lists are things you can find at a standard grocery store in November, not specialty items that require a separate trip.
1. Cheesy Broccoli Rice Casserole

Eight ingredients, one pan, no dairy. The “cheese” comes from a blended cashew or nutritional yeast sauce, which gives the dish a genuinely creamy texture rather than a watery substitute. Because the rice cooks inside the casserole, there’s no separate pot to wash. If you’re cooking for someone with a nut allergy, sunflower seeds blended with nutritional yeast work as a cashew replacement in most sauces like this. This is the one I’d make first, partly because it’s the simplest, and partly because broccoli rice casserole is the dish non-vegans are least likely to raise an eyebrow at.
2. Vegan Pot Pie Casserole

Pot pie filling, baked in a dish without the fussy individual crusts. That alone saves a significant amount of time. The filling typically uses a roux-based sauce with vegetable broth, which sets up thicker than you’d expect after baking. I assemble mine the night before and let the flavours settle in the fridge, then bake it fresh on the day. One honest caveat: if your table has people who care deeply about proper pastry, the casserole format won’t fully replace a traditional pie top. For everyone else, it’s far less stressful to make.
3. Vegan Mexican Casserole

Layered corn tortillas, black beans, and salsa make this one of the more filling options on the list. It’s the casserole to reach for when the holiday spread needs real protein that isn’t imitating meat. The layering technique matters: tortillas act as a structural divider between layers, which keeps the whole thing from collapsing when you serve it. Press each layer down firmly before adding the next. Leftovers hold up well the next day and are arguably better cold, which makes this one genuinely practical for a holiday where you want to reduce Day-Two cooking to almost nothing.

4. Greek Style Green Bean Casserole

This is fasolakia lathera, the Greek braised green bean dish cooked low and slow in olive oil and tomato until the beans are completely tender and have absorbed the sauce. It’s nothing like the cream-of-mushroom version most North Americans grew up with, which is exactly why it earns a place on this list. The olive oil is not optional: it’s the reason the dish is filling and flavourful. You’re looking at a generous pour, roughly half a cup or more for a full batch. Serve it at room temperature if oven space is tight; it actually tastes better that way.
5. Vegan Tater Tot Green Bean Casserole

Tater tots replace the fried onion topping here, and the result is crispier and more satisfying than the original. The mushroom-based sauce is made from scratch rather than from a tin, which genuinely changes the final flavour. Assemble the filling the day before and keep the tots separate in the freezer, then top and bake on the day so they go in frozen and crisp. Double the batch if you’re feeding more than six people. A single dish goes faster than you’d expect when tots are involved.

6. Cheesy Vegan Cauliflower Casserole

Buttery breadcrumbs on top, a cashew-based cheese sauce running through the layers, and it happens to be completely vegan. Cutting the cauliflower into uniform florets matters for even cooking; pieces that are too large stay dense in the centre while the outside browns. The cheese sauce can be blended and refrigerated two days ahead if you want to lighten the day-of prep. Add the breadcrumb topping fresh before baking so it stays crisp rather than going soggy in the fridge overnight.
7. Vegan Buffalo Cauliflower Casserole

Hot sauce and cauliflower in a baked format is genuinely a good combination, and this recipe commits to it properly. The buffalo flavour comes through without being so sharp it overwhelms the rest of the table. It works particularly well next to something mild, like the potato casserole below. Worth noting: buffalo sauce brands vary a lot in sodium and heat level, so taste the sauce before you use the full quantity. This is the most unusual pick on the list, and I mean that as a recommendation.
8. Vegan Potato Casserole

What sets this apart from a standard potato bake is a macadamia and gluten-free breadcrumb topping that produces a crunch you don’t expect. The sauce is oil-free, so the whole casserole is lighter than it looks. Thin, even potato slices are key: a mandoline makes this faster and more consistent, though a steady hand with a sharp knife works fine. Potatoes are also the one dish at a Thanksgiving table that nearly everyone eats without negotiation, which makes this a reliable anchor when you’re unsure of your guests’ preferences.
9. Vegan Vegetable Bean Casserole

Brown rice, broccoli, carrots, celery, and beans baked in a creamy sauce: this one functions as a complete meal rather than a side dish. The legumes add enough protein that vegan guests can eat it as their main, while everyone else treats it as a hearty accompaniment. It’s gluten-free as written, which reduces the number of dietary conversations you need to have at the table. One thing to get right: brown rice needs adequate liquid and time to cook through inside a casserole, so follow the recipe’s liquid ratios carefully rather than guessing.

10. Broccoli Casserole Recipes
This last slot points to our own roundup of 10 Comforting Broccoli Casserole Recipes rather than a single dish, because broccoli casseroles are genuinely varied enough to deserve their own page. The roundup covers styles with a cheesy sauce base and others with a crumb topping. Broccoli casseroles are among the most forgiving dishes to make ahead: they reheat without separating the way some cream-based dishes do. The collection includes options suited to gluten-free and nut-free households, so it’s worth checking before you finalise your menu.

Tips That Apply to All of These
- Assemble any casserole the night before and refrigerate it unbaked. Add ten to fifteen minutes to the baking time if it’s going into the oven cold from the fridge.
- Cashew-based sauces need to be blended very smooth before baking, otherwise the texture stays grainy. Soaking the cashews for at least four hours (or overnight) makes blending faster and the sauce creamier.
- Breadcrumb toppings go on in the last fifteen minutes of baking, or added fresh before the final bake if you’ve pre-assembled the dish. Put them on too early and they absorb moisture and lose their crunch.
- Cover casseroles with foil for the first two-thirds of the baking time to prevent the top from browning before the centre is cooked through, then remove it for the final stretch to crisp the topping.
- Taste and season the filling before it goes into the dish. Once baked, it’s difficult to fix a casserole that needed more salt at the start.
- To reheat, cover the dish with foil, add a splash of vegetable broth (two to three tablespoons for a standard 9×13 dish), and warm at 350°F until heated through. This prevents drying out and keeps the texture close to fresh-baked.
FAQ
Can I make vegan casseroles ahead of time for Thanksgiving?
Most of the casseroles on this list can be assembled a full day ahead and kept covered in the refrigerator. Bake them on the day, adding a little extra time to account for the cold start. The exceptions are toppings like tater tots or breadcrumbs, which should go on right before baking so they stay crisp.
What makes a casserole filling enough to serve as a main dish?
Protein and starch are the two things that make a casserole feel like a complete meal rather than a side. The vegetable bean casserole and the Mexican casserole both include legumes, which adds protein without any processed substitutes. Pairing any of the others with a side of quinoa or lentils also works if you want to bulk up a lighter dish.
How do I keep vegan casseroles from tasting bland?
Salt the vegetables before they go in, season the sauce separately, and taste the assembled filling before baking. Nutritional yeast, smoked paprika, garlic, and a small amount of apple cider vinegar or lemon juice at the end all add depth without complicating the recipe. The vinegar or lemon is easy to skip and easy to miss when it’s absent, so don’t.
Are these casseroles suitable for people who are both vegan and gluten-free?
Several are gluten-free as written, including the cheesy broccoli rice casserole, the Greek green bean casserole, and the vegetable bean casserole. For the others, the most common swap is gluten-free breadcrumbs in place of standard ones, or a gluten-free flour for any roux. Check the linked recipes for specifics, since formulations vary.
