The best fall casseroles for dinner are one dish bakes built on autumn produce like squash, potatoes, cabbage, mushrooms and beans, assembled ahead and baked until the top turns golden. This collection gathers 24 of them, from creamy gratins and layered lasagnas to hearty bean and lentil bakes. Most are vegetarian or vegan, all of them reheat well, and several freeze whole. Pick one tonight and dinner is handled for the next two evenings too.
How to Choose the Right Fall Casserole
Choose a fall casserole by matching the dish to your evening rather than the other way round. If you have twenty minutes of hands on time, reach for a pasta bake or a cheesy vegetable gratin. If you are feeding guests, pick a layered lasagna, a moussaka or a pot pie that slices cleanly and looks generous on the table. For meal prep, favour bean, lentil and potato bakes, which keep their texture after three or four days in the fridge. Match the pan size to your servings as well, because a crowded dish steams instead of browning.

Classic Comfort Casseroles
These are the familiar, filling bakes that made casserole season famous in the first place.
Potato and ‘Meatballs’ Casserole
Sliced potatoes and plant based meatballs bake together in a savory tomato sauce until the top goes golden and the edges bubble. It tastes like a long Sunday lunch but needs only one dish, and it reheats beautifully for days. Tip: shape and brown the meatballs the night before, then assemble straight from the fridge on a busy evening.

Cabbage Casserole with Rice
Slowly softened cabbage folded through rice and a rich tomato base, then baked until everything melts into one another. Humble, filling and cheap enough to build from a single autumn cabbage. Tip: sauté the cabbage until it actually takes on colour before assembling, because that caramelisation is what gives the finished bake its depth.
Get the recipe
Cheesy Cabbage Casserole
The same cozy cabbage base, now blanketed in mozzarella that browns into a stretchy golden crust. Naturally low in carbs and substantial enough to serve as a main with nothing but bread alongside. Tip: pat the cooked cabbage dry before the cheese goes on, so the casserole bakes creamy rather than watery.
Get the recipe
Vegan Green Bean Casserole
Crisp green beans in a silky mushroom cream, finished with a tangle of crunchy fried onions. It hits every note of the American holiday classic without any dairy, and it works just as well on an ordinary Tuesday. Tip: scatter the fried onions on only for the last ten minutes so they stay properly crisp.
Get the recipe
Hasselback Casserole
Potatoes sliced accordion style and packed upright in the dish, so every ridge crisps while the bases stay soft and creamy. It looks like far more effort than it takes. Tip: rest each potato in the bowl of a wooden spoon while you slice, and the spoon stops your knife before it cuts all the way through.
Get the recipe
Vegan Scalloped Potatoes
Wafer thin potato rounds baked slowly in garlicky plant cream until the layers collapse into something spoonable and rich. Full dauphinoise comfort, entirely dairy free. Tip: slice the potatoes on a mandoline for even thickness, since uneven slices are the usual reason the middle stays firm while the surface starts to scorch.

Cozy Pasta Bakes and Lasagnas
Layered, saucy and endlessly reheatable, these are the casseroles that feed a full table without stress.
Vegetarian Lasagna, Traditional Italian Recipe
The traditional Italian build with the ragù swapped for a slow simmered vegetable sauce, layered with béchamel and pasta sheets. This is the casserole people request by name at family dinners. Tip: let the baked lasagna rest for twenty minutes before cutting, so the layers set and every square lifts out cleanly.
Get the recipe
Vegan Lasagna with Mushrooms
Earthy mushrooms cooked down until deeply savory, layered with pasta and a creamy dairy free white sauce. The mushrooms carry all the umami here, so nobody at the table misses the cheese. Tip: cook the mushrooms in a wide pan in batches, because crowding makes them steam and release water into the finished lasagna.
Get the recipe
Mushroom Lasagna Roll-ups
Individual pasta rolls stuffed with mushrooms and a creamy filling, standing upright in a bath of tomato sauce. Portioning is built in, which makes serving guests effortless and plating look intentional. Tip: lay the cooked sheets flat on a damp tea towel while you fill them, so they do not dry out and tear as you roll.

Greek Pasta Casserole, Vegan Pastitsio
Greece’s answer to lasagna: tubular pasta, a cinnamon warmed lentil sauce and a thick béchamel cap that puffs and browns in the oven. The spicing makes it feel unmistakably autumnal. Tip: pour the béchamel over while it is still hot and pourable, then smooth it with the back of a spoon for that signature flat golden top.
Get the recipe
Vegan Stuffed Pasta Casserole
Large pasta shells piped full of a savory filling, nestled into sauce and baked until the exposed edges crisp. Assembling it is oddly relaxing, and it freezes better than almost any other bake in this list. Tip: boil a handful of extra shells, because a few always split in the pot and you will be glad of the spares.
Get the recipe
Tomato Pasta Bake
Pasta, roasted tomatoes and eggplant tossed together and baked until the sauce clings and the top edges frizzle. Weeknight simple, pantry friendly and finished with one pan to wash. Tip: undercook the pasta by two minutes before it goes into the oven, so it finishes perfectly rather than turning soft in the sauce.
Get the recipe
Savory Pumpkin Lasagna
Sheets of pasta layered with silky pumpkin purée and cheese, a savory turn on the flavour most people file under dessert. It is hearty, gently sweet and keeps beautifully for days. Tip: season the pumpkin layer assertively with salt and nutmeg, otherwise the natural sweetness flattens the whole dish.

Squash, Pumpkin and Sweet Potato Bakes
Peak autumn produce, roasted and baked until sweet, caramelised and impossible to stop eating.
Cheesy Baked Butternut Squash
Chunks of butternut roasted until the edges caramelise, then covered with cheese and returned to the oven to blister. Sweet, salty and lightly charred in the same forkful. Tip: cut the squash into even cubes so they finish at the same moment, and roast on a lower shelf if you want more browning underneath.
Get the recipe
Pumpkin Pot Pie
A savory pot pie built on roasted pumpkin and vegetables under a crisp pastry lid that shatters when you break through it. This is the one to make when you want the table to go quiet for a second. Tip: cool the filling before topping with pastry, because trapped steam is what turns a pot pie lid soggy underneath.
Get the recipe
Vegan Sweet Potato Casserole
Mashed sweet potato baked under a nutty, lightly sweet topping until the surface turns crunchy. It sits somewhere between side dish and dessert, which is exactly why it disappears first. Tip: bake the sweet potatoes whole instead of boiling them, so the flesh concentrates rather than soaking up water.
Get the recipe
Sweet Potato Gratin with Gruyere Cheese
Thin sweet potato layers baked in cream with sharp, nutty Gruyère melting between them. The cheese cuts straight through the sweetness and leaves you with a bronzed, blistered top. Tip: cover the dish with foil for the first half of baking, then uncover, so the centre cooks through before the surface takes colour.
Get the recipe
Sweet Potato Shepherd’s Pie
A savory lentil and vegetable base under a bright orange sweet potato mash, forked into peaks that crisp in the oven. Cozy, filling and completely meat free. Tip: drag a fork across the mash before baking, since those ridges are exactly where the crunchy browned bits form.
Get the recipe
Hearty Butternut Squash Rice Casserole
Rice, butternut squash and aromatics baked together into a soft, comforting one dish meal. It stretches a modest amount of vegetables into dinner for a crowd without much effort. Tip: use a tight fitting lid or a snug sheet of foil so the rice steams evenly instead of drying out around the edges.
Get the recipe
Bean, Lentil and Vegetable Gratins
Protein rich bakes that keep you full through the coldest evenings and taste even better the next day.
Easy Vegetarian Cassoulet (French White Bean Casserole)
A French inspired white bean bake, slow cooked with herbs and vegetables until the beans turn creamy and a crust forms across the top. Rustic, deeply savory and arguably better on day two. Tip: break the crust and stir it back in halfway through baking, the traditional trick that builds layers of texture.
Get the recipe
Lentils Gratin with Vegetables
Brown lentils and roasted autumn vegetables baked under a golden gratin top, giving you protein and comfort in the same spoonful. Inexpensive and endlessly adaptable to whatever is left in the vegetable drawer. Tip: cook the lentils just short of tender before baking, so they hold their shape instead of collapsing into purée.
Get the recipe
Eggplant Casserole, Vegan Greek Moussaka
Roasted eggplant layered with a spiced lentil sauce and a thick creamy topping, baked until the surface sets and browns. All the warmth of the Greek classic, none of the dairy or meat. Tip: salt the eggplant slices for half an hour and blot them dry, which draws out moisture and stops the layers sliding apart.
Get the recipe
Cheesy Cauliflower Casserole
Tender cauliflower florets under a blanket of melted cheese, baked until the exposed tips catch and crisp. Light on carbs, generous on comfort and quick enough for a weeknight. Tip: roast the cauliflower briefly before saucing it, since raw florets release water that thins the cheese sauce as it bakes.
Get the recipe
Spinach and Cauliflower Gratin
Cauliflower and wilted spinach folded into a creamy sauce, finished with a crumb and cheese topping that bakes to deep gold. Green, rich and surprisingly elegant for a midweek dinner. Tip: squeeze the cooked spinach hard in a clean towel before it goes in, or the gratin will pool with liquid at the bottom.

Frequently Asked Questions
What makes a casserole a fall casserole? A fall casserole leans on autumn produce and slow oven heat: squash, pumpkin, potatoes, sweet potatoes, cabbage, cauliflower, mushrooms, beans and lentils. Warming spices such as nutmeg, cinnamon, thyme and smoked paprika push it further into the season. The format matters too, since everything cooks together in one dish and comes out bubbling.
Can I make these casseroles ahead of time? Yes, and most of them improve for it. Assemble the casserole up to 24 hours in advance, cover it tightly and refrigerate unbaked. Take it out while the oven heats so it loses the fridge chill, then add roughly 10 to 15 minutes to the baking time. Toppings that should stay crisp, like fried onions or breadcrumbs, go on just before baking.
Can fall casseroles be frozen? Bean, lentil, pasta and tomato based casseroles freeze very well for up to three months, either whole or in portions. Cool completely first, then wrap in a double layer to prevent freezer burn. Dishes heavy on potatoes in cream or on delicate dairy toppings can turn grainy, so those are better eaten fresh or within a few days from the fridge.
What oven temperature is best for a casserole? Most vegetable casseroles bake well at 180 to 200 C, which is about 350 to 400 F. Lower heat suits dense dishes like potato gratins that need the centre to cook through, while higher heat is better for pasta bakes and cheesy tops you want browned. Covering with foil for the first half and uncovering for the second gives you both.
How do I stop my vegetable casserole from being watery? Pre cook the wettest vegetables before assembling. Salt and blot eggplant, squeeze cooked spinach dry, sauté cabbage and mushrooms until their liquid has evaporated, and roast squash rather than boiling it. Using a wide dish rather than a deep one also helps, since more surface area lets steam escape while it bakes.
What should I serve with a fall casserole? Something sharp and fresh to balance the richness. A green salad with a mustard vinaigrette, quick pickled onions, or steamed greens with lemon all work. Crusty bread is welcome with saucy bean and tomato bakes, while lighter vegetable gratins take well to a grain such as rice, farro or quinoa on the side.
