"My only modifications were to add fresh oregano with the fresh basil in the sauce and chopped spinach (1 whole bunch) in each layer right before adding the sauce for the next layer. The spinach adds a whole lot more leafy green vegetables so it's not just breaded eggplant in this dish." —Craig, Simply Recipes Reader

2. Chili Mac and Cheese

"The chili mixture is mild in terms of the spice level, so heat seekers might want to add in some crushed red pepper flakes or a diced jalapeño." —Aaron Hutcherson, Simply Recipes Contributor

3. Sweet Potato Casserole With Pecans

"To do most of the work ahead, but still keep the crunchiness of the topping, make the whole casserole ahead of time but leave the topping off. Refrigerate the unbaked casserole up to 2 days ahead of time. To bake, bring to room temperature. Make the topping, add it to the casserole, and pop in the oven." —Lisa Lin, Simply Recipes Contributor

4. Chicken and Rice Casserole

"This recipe assumes the rice requires about 1 1/2 cups of liquid per cup of rice to cook. Some rice varieties, such as brown rice, require more liquid (and a longer cooking time). Adjust recipe accordingly." —Elise Bauer, Simply Recipes Founder

5. Cheeseburger Casserole

"Keeping the cooked pasta separate from the other prepped ingredients prevents the pasta from absorbing too much liquid in storage and getting mushy." —Eric Jones, Simply Recipes Contributor

6. Cauliflower Gratin

"To make it lower carb, we substituted half and half for the milk, chickpea flour for the flour, and almond meal for the breadcrumbs. It looked fabulous and got lots of compliments." —Emily, Simply Recipes Reader

7. Turkey Black Bean Quinoa Bake

"I made this with cooked ground turkey, and it was AWESOME!!! Perfect leftovers for lunches." —Lisa, Simply Recipes Reader

8. Stuffed Shells

"When boiling the jumbo shells, check the directions on the package for the cooking time and then subtract 1-2 minutes, since the shells are going to bake again in the oven and you don’t want them to be too soft at the start." —Sally Vargas, Simply Recipes Contributor

9. Twice Baked Potato Casserole

"The joy of a baked potato dinner is the endless possibilities for toppings, and that joy exists with this casserole too! Our recipe starts with the classics: Cheddar cheese, bacon bits, and scallions; but use this as a jumping off point and feel free to swap in some of your favorites." —Brianne Ross, Simply Recipes Contributor

10. Philly Cheesesteak Casserole

"Add diced jalapeños or roasted poblano peppers to the filling for a spicier version." —Nick Evans, Simply Recipes Contributor

11. Cheesy Spaghetti Squash Casserole

"Delicious! I had about 4 ounces of breakfast sausage in my fridge that needed to be used up, so I sautéed that with the onions. This was really really good. Will definitely make again." —Donna, Simply Recipes Reader

12. French Toast Casserole

"You can absolutely make this recipe straight through and bake it right away, but for a totally hands-off and hassle-free morning, assemble it the night before and bake it in the morning when you get up. This actually gives the bread even more time to soak up the milk, which makes the inside of the baked casserole more custardy and decadent." —Lisa

13. Tuna and Tomato Pasta Casserole

Get Recipe: Tuna and Tomato Pasta Casserole

"Tuna packed in olive oil is highly recommended for this recipe. If all you have is tuna packed in water, you can try draining it and then adding olive oil to the can, and letting it soak in the olive oil in the fridge for several hours." —Elise

14. Trinidadian Macaroni Pie

Get Recipe: Trinidadian Macaroni Pie

"Bucatini is a popular choice for macaroni pie, but you can certainly use elbows. The idea is to choose a tubular pasta shape that will capture the seasonings and delicious sauce inside the noodle." —Alica Ramkirpal-Senhouse, Simply Recipes Contributor

15. Chicken Taco Casserole

Get Recipe: Chicken Taco Casserole

"This is a layered casserole and my favorite trick is to line the bottom of the dish with crispy corn tostadas so that when baked, the bottom doesn't stick to the dish." —Nick

16. Potatoes Au Gratin

Get Recipe: Potatoes Au Gratin

"To prep the potatoes, peel them (or don’t if you want a more rustic dish) and slice them thinly (approximately 1/8-inch) with a knife, a mandoline, or the easiest by far, the 4mm slicing disk of your food processor." —Sally

17. Monte Cristo Croissant Casserole

Get Recipe: Monte Cristo Croissant Casserole

"Buy your croissants in advance, as stale ones will soak up the egg mixture better." —Jasmine Smith, Simply Recipes Recipe Developer and Tester

18. Three Sisters Casserole with Cornbread Topping

Get Recipe: Three Sisters Casserole with Cornbread Topping

"Very good! The seasonings really give the veggies flavor. I used sweet potato instead of squash. I did not make the cornbread topping because I didn't have cornmeal but will try it next time. I served over brown rice and quinoa to add some more calories and make it a meal. Also added some shredded cheese!" —Heather, Simply Recipes Reader

19. Ham and Cheese Pasta Bake

Get Recipe: Ham and Cheese Pasta Bake

"Nutmeg is an essential spice for the white sauce. That said, it is easy to overdo it. Start with a small amount, 1/4 teaspoon, and add more if needed." —Elise

20. Reuben Casserole

"This casserole is the perfect make-ahead meal. Make this recipe the night before, cover, and keep in the fridge unbaked, then just pop it in the oven when you get home from work." —Summer Miller, Simply Recipes Contributor

21. Scalloped Potatoes with Caramelized Onions and Gruyere
