Slow Cooker Ground Beef and Corn Casserole
Description
This Slow Cooker Ground Beef and Corn Casserole is an easy comfort-food dinner made with lean ground beef, sweet corn, creamy soup, sour cream, and cheddar cheese. The ingredients come together in the slow cooker for a warm, filling meal with very little hands-on work.
The beef is browned first to build a rich savory base, then mixed with corn and a creamy sauce before slow cooking. Melted cheddar adds a cheesy finish, while optional green onions, parsley, or crushed tortilla chips give the casserole extra flavor and texture.
This family-friendly casserole is a practical choice for busy weeknights, casual gatherings, potlucks, and make-ahead meals. It makes 6–8 servings, so leftovers can be packed for lunch or reheated for another dinner.
Ingredients
Main Ingredients
- 1½ lbs (680g) lean ground beef: Choose lean beef to limit excess grease while keeping the casserole flavorful.
- 1 medium onion, diced: Onion adds savory flavor and a slightly sweet taste as it cooks.
- 2 cloves garlic, minced: Fresh garlic gives the beef mixture a deeper flavor.
- 2 cans (15 oz each) whole kernel corn, drained: Corn adds sweetness, texture, and color to the casserole.
- 1 can (10.5 oz) cream of mushroom soup: The soup creates the creamy base and helps bind the ingredients.
- 1 cup sour cream: Sour cream adds richness and a mild tangy flavor.
- 1½ cups shredded cheddar cheese: Cheddar melts into the casserole and creates a cheesy topping.
- 1 teaspoon salt: Salt brings out the flavor of the beef, corn, and creamy sauce.
- ½ teaspoon black pepper: Black pepper adds mild seasoning without overpowering the other ingredients.
- 1 teaspoon paprika: Paprika provides gentle warmth and a subtle smoky note.
Optional Toppings
- Chopped green onions: Add them after cooking for a fresh, mild onion flavor.
- Fresh parsley: Parsley gives the finished casserole a fresh look and light herbal taste.
- Crushed tortilla chips: Sprinkle them on individual servings for a crunchy contrast.
Instructions
Step 1: Brown the Beef
Heat a large skillet over medium heat and add the ground beef. Cook until no longer pink, breaking it into small pieces as it browns.
Add the diced onion and minced garlic. Cook for another 2–3 minutes, until the onion begins to soften and the garlic becomes fragrant.
Drain excess grease from the skillet if needed. Removing extra fat keeps the casserole from becoming overly oily during slow cooking.
Step 2: Mix the Casserole
Place the cooked beef mixture in a large mixing bowl. Add the drained corn, cream of mushroom soup, sour cream, 1 cup of shredded cheddar cheese, salt, black pepper, and paprika.
Stir until the beef, corn, seasoning, and creamy ingredients are evenly combined. Mixing everything before transferring it to the slow cooker helps distribute the flavors throughout the casserole.
Step 3: Transfer to Slow Cooker
Lightly grease the inside of your slow cooker to make serving and cleanup easier.
Pour the beef and corn mixture into the slow cooker. Spread it into an even layer so it cooks consistently from edge to center.
Step 4: Add Cheese
Sprinkle the remaining ½ cup of shredded cheddar cheese evenly over the top.
The cheese will melt during cooking and create a rich, creamy layer over the casserole.
Step 5: Cook
Cover the slow cooker with its lid and cook according to your preferred setting.
- LOW: Cook for 4–5 hours.
- HIGH: Cook for 2–3 hours.
Avoid repeatedly removing the lid because heat escapes each time, which can extend the cooking time.
The casserole is ready when it is hot throughout and the cheese has melted completely.
Step 6: Serve
Turn off the slow cooker and allow the casserole to rest for about 10 minutes before serving. This short resting period allows the creamy mixture to settle and makes portions easier to scoop.
Top each serving with chopped green onions, fresh parsley, or crushed tortilla chips if desired.
Serve the casserole warm with a simple green salad, steamed vegetables, garlic bread, or dinner rolls.
Servings
This recipe makes approximately 6–8 servings, depending on portion size.
It works well for family dinners because the slow cooker keeps the casserole warm while everyone gets ready to eat. For a larger gathering, serve it alongside simple vegetable dishes or a fresh salad.

Health Benefits
High in Protein
Ground beef provides protein that helps support normal muscle function and contributes to a satisfying meal. Using lean ground beef also helps reduce the amount of excess fat.
Source of Fiber
Corn contributes dietary fiber along with carbohydrates and other nutrients. Keeping the corn in the recipe also adds texture and natural sweetness.
Complete Comfort Meal
This casserole combines beef, vegetables, dairy, and seasonings in one dish. Pairing it with a green salad or steamed vegetables can add more variety to the meal.
Easy Slow Cooker Recipe
Most of the preparation involves browning the beef and combining the ingredients. Once the mixture is in the slow cooker, it requires little hands-on attention.
Great for Leftovers
The recipe makes several servings and reheats well when stored properly. Leftovers can provide a convenient lunch or dinner during the following days.
Recipe Notes
Use lean ground beef when possible because it produces less grease and keeps the creamy sauce from becoming too heavy.
Cream of chicken soup can replace cream of mushroom soup if you prefer a different flavor. The consistency should remain similar when making this substitution.
Fresh or frozen corn can replace canned corn. If using frozen corn, thaw it first and drain any excess liquid.
The casserole becomes slightly thicker as it cools. Letting it rest for about 10 minutes before serving helps it reach a better serving consistency.
For a different flavor profile, try pepper jack instead of cheddar. You can also add diced bell peppers, jalapeños, or cooked rice.
Helpful Tips
Brown the ground beef before adding it to the slow cooker. This step improves the flavor and lets you remove excess grease before the creamy ingredients are added.
Drain canned corn well so extra liquid does not thin the casserole.
Shred cheddar cheese yourself when possible for smooth melting. Pre-shredded cheese can contain ingredients that affect its melting texture.
Add cooked rice or pasta if you want to turn the casserole into an even heartier meal. Make sure the rice or pasta is already cooked before mixing it in.
For extra vegetables, stir in diced bell peppers before slow cooking. Green, red, or yellow peppers all work well.
If you enjoy spicy food, add diced jalapeños, chili powder, or your favorite hot sauce.
For a crunchy finish, add crushed tortilla chips or crispy fried onions immediately before serving. Adding them at the end helps maintain their texture.
If preparing the casserole ahead, keep the assembled mixture refrigerated until you are ready to cook it. Do not leave perishable ingredients at room temperature for extended periods.
