Why This Cheesy Ground Beef Casserole Is a Weeknight Winner

This Cheesy Ground Beef Casserole is more than just a recipe; it’s a lifeline on busy weeknights.

I’ve tweaked this recipe countless times over the years, depending on what I have on hand. Sometimes I add a can of drained black beans for extra protein and fiber, or a handful of chopped spinach for a sneaky dose of greens. The possibilities are endless!

What You’ll Need for Cheesy Ground Beef Casserole

Ground Beef and Rice for Cheesy Ground Beef Casserole

• Ground Beef: I prefer using 80/20 for flavor—it just makes everything taste richer. But lean ground beef works too; just drain off any excess grease after browning. Look for ground beef that is bright red and feels firm to the touch. Avoid packages with excessive liquid. If using lean ground beef, consider adding a tablespoon of olive oil to the skillet while browning to prevent it from drying out.
• Cooked Rice: Use your favorite type of rice. We typically use long-grain white rice, but for added texture, quick-cooking brown rice can work in a pinch. Make this ahead of time. Day-old rice works particularly well in casseroles, as it tends to hold its shape better and doesn’t get mushy. You can also use leftover risotto or even quinoa for a healthier twist. Make sure the rice is cooled slightly before adding it to the beef mixture to prevent it from overcooking. Don’t rinse your rice after cooking if you want it to be a bit sticky, as it helps bind the casserole together.

Aromatics for Cheesy Ground Beef Casserole

• Onion: Yellow or white onion, finely chopped, builds a savory foundation that’s absolutely essential. Dicing the onion finely ensures that it cooks evenly and blends easily into the casserole. If you’re short on time, you can use pre-chopped onions from the produce section. Shallots can also be used for a slightly milder flavor. If you don’t have fresh onions on hand, onion flakes can be substituted. Use about 1 tablespoon of dried onion flakes for every 1/2 cup of chopped fresh onion.
• Garlic: Freshly minced garlic provides a punchy flavor that complements the beef, adding warmth and depth. Use a garlic press for easy mincing, or finely chop it with a sharp knife. Jarred minced garlic can be used in a pinch, but fresh garlic provides the best flavor. For a mellow roasted garlic flavor, roast a whole head of garlic in the oven until soft and then squeeze the cloves into the beef mixture. This adds a wonderful depth of flavor to the casserole.

Seasonings for Cheesy Ground Beef Casserole

• Salt: Enhances all the flavors in the casserole. Don’t be shy! Kosher salt or sea salt is preferred for its pure flavor. Adjust the amount of salt to your liking, but remember that cheese also contains salt. Start with a smaller amount and add more to taste.
• Black Pepper: Adds a subtle warmth and spice to balance the richness. Freshly ground black pepper is always best for the most potent flavor. White pepper can be used as a substitute if you prefer a milder flavor and don’t want black specks in your casserole.
• Garlic Powder: Reinforces the garlic flavor; this is one of my go-to dinners! It adds an extra layer of savory goodness. Garlic powder is a convenient way to add consistent garlic flavor throughout the casserole. You can also use granulated garlic, which has a slightly coarser texture.
• Onion Powder: Complements the fresh onion and adds depth of flavor. Onion powder is made from dehydrated onions and provides a concentrated onion flavor. It is a pantry staple for adding savory notes to dishes.
• Italian Seasoning: A blend of herbs that adds a classic Italian flavor; it’s a quick way to add complexity. Look for Italian seasoning blends that include oregano, basil, thyme, rosemary, and marjoram. You can also make your own Italian seasoning blend by combining equal parts of each herb.

Sauce Ingredients

• Tomato Sauce: Forms the base of the sauce and adds a rich, tomatoey flavor to the meat mixture. Use your favorite brand—I really like the organic ones. Tomato sauce consistency can vary between brands, but for this recipe, you want a smooth, pourable sauce, not too thick. You can substitute tomato puree or crushed tomatoes if you don’t have tomato sauce on hand, but be sure to adjust the seasoning accordingly.
• Beef Broth: Adds moisture and deepens the savory flavor of the mixture. It helps keep everything moist and delicious. Low-sodium beef broth is recommended to control the saltiness of the casserole. You can also use chicken broth or vegetable broth as a substitute, but beef broth will provide the boldest flavor. Homemade beef broth adds even more depth—if you make your own broth, use it here!

Vegetables and Add-Ins

• Canned Diced Tomatoes: Add texture and a bit of acidity to balance the richness. Drain them well. Draining the diced tomatoes prevents the casserole from becoming too watery. Fire-roasted diced tomatoes add a smoky flavor. You can also use fresh diced tomatoes, especially if they are in season.
• Frozen Corn: Adds a touch of sweetness and pops of color. Feel free to swap it for other veggies like peas or green beans! I try to sneak in as many veggies as possible. Frozen corn is convenient and readily available. You can use fresh corn kernels if available—just cook them slightly before adding them to the beef mixture. Other vegetable options include diced carrots, bell peppers, or zucchini.

Cheese Topping for Cheesy Ground Beef Casserole

• Shredded Cheddar Cheese: A must-have for that cheesy, melty topping. You can also use a blend of cheddar and Monterey Jack, or even Pepper Jack for a kick. Don’t skimp! Sharp cheddar, mild cheddar, or a combination of both will work well. Pre-shredded cheese is convenient, but freshly shredded cheese melts more smoothly and evenly.
• Shredded Mozzarella Cheese: For the ultimate cheese pull, you can’t skimp on mozzarella. It melts beautifully and adds that classic stretchy texture. Part-skim mozzarella melts better. For even cheesier results, combine the mozzarella and cheddar.

How to Make Cheesy Ground Beef Casserole

Make the Ground Beef Mixture for Cheesy Ground Beef Casserole

1. Step 1: Brown the beef. In a large skillet, I use my trusty cast iron, over medium-high heat, brown the ground beef. Drain off any excess grease; nobody likes a greasy casserole. Break the ground beef into smaller pieces as it cooks using a spatula or wooden spoon. This helps it cook evenly. Patting the ground beef dry with paper towels before browning can help it brown more quickly.
2. Step 2: Sauté aromatics. Add the chopped onion and cook until softened, about 5 minutes, then add the minced garlic and cook for another minute until fragrant. Your kitchen should smell amazing right now! Stir the onions frequently to prevent them from burning. If the onions start to stick to the skillet, add a tablespoon of water or broth to deglaze the pan.
3. Step 3: Season the beef. Stir in the salt, pepper, garlic powder, onion powder, and Italian seasoning. I usually eyeball it, but start with about a teaspoon of each. Adjust the seasoning to your liking based on your taste preferences. Taste the mixture after adding the spices and adjust as needed.
4. Step 4: Add the sauce and tomatoes. Pour in the tomato sauce, beef broth, and diced tomatoes. Simmer for 10 minutes, stirring occasionally, to allow the flavors to meld. Don’t forget to taste and adjust the seasoning! Sometimes I add a pinch of red pepper flakes for a little heat. Simmering the sauce allows the flavors to combine. If you want a thicker sauce, you can simmer it for longer.

How to Assemble Cheesy Ground Beef Casserole with Rice

1. Step 1: Combine ingredients. In a large bowl, combine the cooked ground beef mixture, cooked rice, and frozen corn. Stir well to combine everything. It should be nice and evenly mixed. Make sure the ground beef mixture has cooled slightly before adding the rice and corn to prevent the rice from overcooking.
2. Step 2: Transfer to baking dish. Pour the mixture into a greased 9×13-inch baking dish. I use cooking spray, but you can also grease it with butter or oil. Using a 9×13-inch baking dish allows for even baking and serving. Using a larger or smaller dish will affect the cooking time.
3. Step 3: Add the cheese. Sprinkle the cheddar and mozzarella cheese evenly over the top of the casserole. Make sure you get cheese all the way to the edges—that’s where the crispy bits come from! Layering the cheeses ensures even melting. Reserve a small amount of cheese to sprinkle on top during the last few minutes of baking for a golden-brown finish.

Bake Cheesy Ground Beef Casserole Until Golden

1. Step 1: Bake. Bake in a preheated oven at 350°F (175°C) for 20-25 minutes, or until the cheese is melted and bubbly and the casserole is heated through. Keep an eye on it; you want the cheese to be golden brown, not burnt. If the cheese starts to brown too quickly, cover the casserole with aluminum foil.
2. Step 2: Let it rest. Let it cool for a few minutes before serving. This helps the casserole hold its shape, and it’ll be less likely to burn your tongue. Resting the casserole allows the flavors to meld further and prevents it from being too watery when served.

Tips for the Perfect Cheesy Ground Beef Casserole

• Don’t overcook the ground beef, as it can become dry and tough. Cook it just until it’s no longer pink.
• For a creamier casserole, stir in a can of cream of mushroom soup or cream of chicken soup into the ground beef mixture. This will add moisture and richness to the casserole.
• Add a layer of crushed tortilla chips or French-fried onions on top of the cheese for extra crunch. This is where you can really make this casserole your own!
• If you’re short on time, use instant rice instead of cooking rice from scratch. Just follow the package directions.
• Spice it up by adding a pinch of cayenne pepper or a dash of hot sauce to the ground beef mixture. This will give the casserole a nice kick.
• For a healthier option, use ground turkey or ground chicken instead of ground beef. You can also add more vegetables, such as spinach, bell peppers, or zucchini.
• Make individual casseroles in muffin tins for easy portion control and serving. This is a great way to pack lunches or have a quick and easy dinner on hand.

How to Serve

Serve this Cheesy Ground Beef Casserole family-style straight from the baking dish. I always think it looks so homey and inviting this way. Garnish with a sprinkle of fresh parsley or chopped green onions for a pop of freshness. A dollop of sour cream or guacamole also complements the flavors nicely. This casserole is comfort food done right. It pairs well with a simple green salad or steamed vegetables. The flavors are best right away, but hold up well for leftovers.

Consider serving this casserole with a side of crusty bread or garlic toast to soak up all the delicious sauce. A colorful fruit salad also provides a refreshing contrast to the richness of the casserole. For a heartier meal, add a side of roasted potatoes or sweet potato fries.

How to Store and Reheat Cheesy Ground Beef Casserole

1. Fridge: Store the assembled casserole in an airtight container in the refrigerator for up to 3 days. It’s great for lunch the next day!
2. Freezer: You can freeze the casserole before or after baking. Wrap it tightly in plastic wrap and then foil, or place it in a freezer-safe container. It can be frozen for up to 2 months. Thaw completely in the refrigerator before baking or reheating.
3. Reheating: Reheat individual portions in the microwave or bake the entire casserole in a preheated oven at 350°F (175°C) until heated through. If baking from frozen, increase the baking time. Add a splash of beef broth when reheating to refresh the moisture—it can dry out a bit.
