Simple Casserole Recipes for a Crowd or Potluck

Last updated: June 17, 2026

Make enough to feed a crowd by bringing a casserole to your next potluck or other gathering. Casseroles also work well to meal prep for the busy week ahead. Using a hearty mix of your favorite ingredients helps make mealtime delicious and stress-free. 

How to make a casserole 

Making a casserole is one of the simplest cooking techniques. Plus, it’s a great way to use up any frozen and refrigerated ingredients you already have on hand.

Step 1: Choose your base 

You’ll want to start your simple casserole recipe with a starch such as pasta or rice. Potatoes, like hashbrowns, are another crowd-pleasing base starch. 

Step 2: Add your protein 

Bulk up your casserole with a filling protein like shredded or ground chicken, beef, or sausage. For a meatless option, beans are a go-to protein source. 

Step 3: Mix in vegetables, seasoning, and flavor 

Frozen vegetables save time—and help clear out your freezer—while adding nutrition to the meal. Add flavor to every bite by mixing in a creamy or tomato-based sauce as well as complementary seasonings. If desired, bring texture to the dish by topping with cheese, breadcrumbs, or crushed crackers. 

Step 4: Cover and bake 

Cover the uncooked casserole with Reynolds Wrap® Everyday Aluminum Foil. Then bake at 350°F to 375°F until bubbly and golden.

Tips for make-ahead casserole dishes

One of the best things about casseroles is how well they freeze. Prepare a double batch on the weekend and freeze one to dish out later when you’re short on time. Most freezer casserole recipes reheat well and taste just as good the second time around. 

Freezing tips: 

  • Use Reynolds Wrap® Everyday Aluminum Foil or airtight freezer-safe containers for best results 
  • Label each casserole with the name and date before freezing and aim to reheat within three months 
  • Thaw overnight in the refrigerator before reheating, instead of heating from frozen
