When the weather cools down, casseroles become a go-to for easy dinners.
This list has 11 options that work well for busy weeknights or relaxed weekends.
They focus on simple prep and flavors that hold up to reheating.
You can make them with pantry staples and fresh produce from the season.
Most can be assembled in advance so dinner is ready when you are.
Helpful Tips Before You Start
These tips will help you assemble the casseroles with less effort and better results.
Roast vegetables first
Roasting squash, Brussels sprouts, or sweet potatoes before mixing them into the casserole builds deeper flavor. It also keeps the final bake time shorter.
Double the recipe for freezing
Most of these casseroles freeze well before or after baking. Portion extras into smaller dishes so you can pull out just what you need on busy nights.
Add crunchy toppings at the end
Breadcrumbs, nuts, or fried onions lose texture if added too early. Sprinkle them on during the last 10 to 15 minutes of baking.
Use an oven-safe skillet when possible
Starting the filling in a cast-iron skillet or Dutch oven means one less pan to wash. It also helps the bottom layer brown nicely.
Butternut Squash and Sausage Lasagna Casserole
This casserole layers sweet roasted butternut squash with savory sausage and classic lasagna noodles. It works well for weeknight dinners or weekend gatherings when you want a filling meal that still feels seasonal.
The finished dish has tender pasta, creamy squash pockets, and a lightly browned cheese top that holds everything together.
Serves 4 people.
Ingredients
- 1 lb Italian sausage, casings removed
- 4 cups butternut squash, peeled and cubed
- 9 lasagna noodles
- 1 1/2 cups ricotta cheese
- 2 cups shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
- 3 cups marinara sauce
- 1 small onion, diced
- 3 cloves garlic, minced
- 2 tbsp olive oil
- 1 tsp dried sage
- Salt and black pepper to taste
Instructions
- Preheat the oven to 375°F. Heat olive oil in a large skillet over medium heat. Add the onion and garlic and cook until softened.
- Add the Italian sausage to the skillet. Cook until browned, breaking it up with a spoon. Season with salt and pepper, then stir in the dried sage and remove from heat.
- Place the butternut squash cubes on a baking sheet. Toss with a little olive oil, salt, and pepper. Roast for 20 minutes until tender.
- Boil the lasagna noodles according to package directions until al dente. Drain and set aside.
- Spread a thin layer of marinara sauce in the bottom of a 9×9 baking dish. Add a layer of noodles, then half the ricotta, half the sausage mixture, half the roasted squash, and a sprinkle of mozzarella.
- Repeat the layers once more. Finish with a final layer of noodles, the remaining marinara, mozzarella, and Parmesan.
- Cover with foil and bake for 25 minutes. Remove the foil and bake 10 more minutes until the cheese is golden. Let rest 5 minutes before serving.
Extra Tips
Roast the squash ahead so it stays in distinct cubes rather than turning to mush during assembly. Leftovers reheat well in a covered dish at 350°F. If you want a milder flavor, use sweet Italian sausage instead of hot.Course: Main Course Cuisine: Italian Equipment: Large skillet, Baking sheet, Large pot, 9×9 baking dish

Ingredients
- 3 cups cooked wild rice

Extra Tips
If the wild rice was cooked ahead and stored in the fridge, let it come to room temperature before mixing so the casserole heats evenly. Leftovers reheat well in a 350 degree oven with a splash of broth stirred in to keep the rice from drying out. For a slightly different flavor, swap the mozzarella for sharp cheddar.Course: Main Course Cuisine: American Equipment: Large skillet, 9×9 baking dish, Mixing bowl

Extra Tips
Assemble the casserole up to a day ahead and keep it covered in the fridge, then add 5-10 minutes to the covered bake time if starting from cold.

- 1/4 tsp black pepper
Instructions
- Preheat the oven to 375°F. Lightly grease a 9×9 inch baking dish and set it aside.
- In a medium saucepan, combine the pearl barley and chicken broth. Bring to a boil, then reduce the heat to low, cover, and simmer for 25 minutes until the barley is tender and most of the liquid is absorbed.
- While the barley cooks, heat the olive oil in a large skillet over medium heat. Add the diced onion and cook for 3 minutes until softened.
- Add the chicken pieces to the skillet along with the salt, pepper, and dried thyme. Cook for 5 minutes, stirring occasionally, until the chicken is lightly browned.
- Stir in the sliced mushrooms and minced garlic. Cook for another 4 minutes until the mushrooms release their liquid and begin to brown.

Extra Tips
If the barley absorbs too much liquid during baking, stir in a splash of warm broth or cream before serving to loosen the texture. Leftovers reheat well in a covered skillet over low heat with a little extra cream to restore creaminess. For a make-ahead option, assemble the casserole up to the baking step, cover, and refrigerate for up to one day before baking.Course: Main Course Cuisine: American Equipment: Large skillet, Medium saucepan, 9×9 baking dish

Ingredients
- 6 cups cubed day-old bread
- 2 tablespoons butter

- 2 garlic cloves, minced
- 3 cups fresh spinach
- 4 large eggs
- 1 1/2 cups whole milk
- 1 1/2 cups shredded Gruyere cheese
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
Instructions
- Preheat the oven to 350 degrees F and lightly grease an 8×8 inch baking dish.
- Melt the butter in a large skillet over medium heat. Add the sliced mushrooms and diced onion. Cook until the mushrooms release their liquid and begin to brown, about 6 minutes.
- Stir in the minced garlic and cook for 1 minute. Add the spinach and cook until wilted, about 2 minutes. Remove the skillet from the heat.
- In a large bowl, whisk together the eggs, milk, salt, and pepper.
- Spread half the bread cubes in the prepared baking dish. Top with half the mushroom spinach mixture and half the shredded Gruyere. Repeat the layers with the remaining bread, vegetables, and cheese.

- Bake for 40 to 45 minutes until the top is golden and the center is set. Let rest for 5 minutes before serving.
Extra Tips
Use day-old bread so it soaks up the custard without becoming mushy. If you want a richer version, replace half the milk with half-and-half. Leftovers reheat well in a 325 degree F oven for 15 minutes. The strata also tastes good at room temperature for a brunch buffet.Course: Breakfast Cuisine: American Equipment: Baking dish, Large skillet, Mixing bowl
