Spicy Pumpkin Chicken Casserole (Easy Fall Dinner)
This spicy pumpkin chicken casserole pairs bite-size chicken thighs with pumpkin and potato in a sriracha-paprika marinade, then bakes hands-off in one dish. Prep runs 25 minutes plus a 30-minute marinate, and it bakes for about 40 minutes, so the whole pumpkin chicken casserole is ready in a little over an hour.
What makes this pumpkin chicken casserole different from a plain roasted vegetable tray is the marinade. Hot paprika, sriracha, and chili flakes soak into the chicken and vegetables before they hit the oven. As a result, the heat and smoke build into every bite instead of sitting on the surface. Chicken thighs stay juicy through the full 40-minute bake, where breast meat would dry out.
Serve this pumpkin chicken casserole over steamed rice with broccoli or Brussels sprouts on the side, and it turns into a full dinner with almost no cleanup. For another warming chicken bake on a busy night, the Chicken Cordon Bleu Pasta Bake is a good one to keep in rotation.

Why You'll Love This Pumpkin Chicken Casserole
- One dish, one bake. Everything marinates and cooks together, so there's no separate pan for the chicken and no separate pan for the vegetables.
- Real heat, not a pepper flake garnish. Sriracha and hot paprika go into the marinade itself, so the spice is built in rather than sprinkled on at the end.
- Chicken thighs that stay tender. Dark meat holds up to the 40-minute bake without turning stringy or dry. That helps avoid a common problem with baked chicken and vegetables.
- Pantry-friendly swaps. Butternut squash stands in for pumpkin with no change to timing, so this pumpkin and chicken casserole works even outside pumpkin season.
- An easy pumpkin casserole for a weeknight. There's no roux, no cheese sauce, and no second pan; it's a marinade, a bowl, and a baking dish.
Key Ingredients
See the recipe card for the complete list of ingredients and quantities.
- Chicken thighs. Boneless, skinless thighs hold their moisture through the full bake. Chicken breast dries out at the same oven time, since it has less fat to keep it tender.
- Fresh pumpkin or butternut squash. Either works interchangeably in this chicken and pumpkin casserole. Cut it into 1-inch cubes so it cooks at the same rate as the potato and chicken. A cooking pumpkin (not a carving pumpkin) gives the best texture; butternut squash is the easier find most of the year. If squash is the one you reach for most, the Butternut Squash Mac and Cheese is another way to use it.
- Hot paprika. This is where a lot of the color and smoky backbone in this pumpkin chicken casserole comes from. Sweet paprika will mute the heat considerably if that's what's on hand.
- Sriracha. Brings acidity along with heat, which keeps the dish from tasting flat the way straight chili powder can. It also helps the marinade cling to the chicken and vegetables.
- Chili flakes. A small amount goes into the marinade, and a pinch more at serving sharpens the heat without changing the flavor base.
How to Make Pumpkin Chicken Casserole
This pumpkin chicken casserole comes together in two stages: a marinade, then a covered-then-uncovered bake.
- Add the pumpkin, potato, chicken, hot paprika, chili flakes, sriracha, and olive oil to a large bowl. Season with salt and combine well so every piece is coated.
- Cover and marinate in the refrigerator for 30 minutes.
- Preheat the oven to 400°F.
- Pour the marinated chicken and vegetables into a 9x13-inch baking dish.
- Cover the dish tightly with aluminum foil.
- Bake for 20 minutes covered.
- Remove the foil and bake for another 15 to 20 minutes, until the chicken is golden brown and the potato and pumpkin are fork-tender.
- Serve hot over rice with broccoli.
What to Serve with This Pumpkin Chicken Casserole
Like most any pumpkin casserole recipe with a spiced marinade, this one wants something plain alongside it to soak up the sauce. Steamed white rice is the classic base here, since it soaks up the paprika-sriracha pan juices. Steamed broccoli or roasted Brussels sprouts add a plain, slightly bitter contrast that balances the heat. For a fall spread with more on the table, a Loaded Green Bean Casserole or a few dishes from these fall appetizer ideas round things out.
Pumpkin Chicken Casserole FAQs
No. Canned pumpkin is a puree and won't hold its shape or texture through baking. Fresh pumpkin or butternut squash, cut into cubes, is what gives this pumpkin chicken casserole its bite.
It has real heat from the sriracha, hot paprika, and chili flakes marinade. Cut the chili flakes in half and swap in sweet paprika for a milder version, or leave the sriracha and hot paprika as written for the full spice level.
Yes. Combine the marinade with the chicken and vegetables up to a day ahead and keep it covered in the refrigerator. Pour it into the baking dish straight from the fridge and add a few extra minutes to the covered bake time.
Chicken breast works, but it dries out faster than thighs at this bake time. Pull it from the oven closer to the 15-minute mark after uncovering, and check for doneness with a thermometer.
Store leftover pumpkin chicken casserole in an airtight container in the refrigerator for up to 3 days. Reheat in a covered dish in a 350°F oven until warmed through, or microwave in short bursts to avoid drying out the chicken.
It freezes reasonably well for up to 2 months in an airtight, freezer-safe container. The potato texture softens slightly after thawing, so this is best as a make-ahead freezer meal rather than a fresh-tasting repeat.
Any oven-safe dish with a similar surface area works for this pumpkin chicken casserole. Keep the chicken and vegetables in a single, mostly even layer so everything bakes at the same rate instead of steaming in a deep pile.
No. This pumpkin chicken casserole skips the canned cream soup base entirely. The sauce here comes from the marinade and the pan juices, not a can, so the flavor is sharper and the texture stays closer to roasted vegetables than a creamy bake.
