What is a “Ground Beef Casserole”?

A Ground Beef Casserole is a baked dish typically made by layering cooked ground beef with vegetables, starch (like pasta or rice), and cheese or a creamy sauce. The beauty of casseroles lies in their versatility—you can easily customize them with your favorite ingredients or whatever you have on hand. Ground beef provides a savory, protein-packed base for the casserole, while other ingredients add texture, flavor, and richness to the dish.

Ingredients List for Ground Beef Casserole

Here are the basic ingredients you’ll need to make a simple ground beef casserole. Feel free to adjust quantities based on your preferences or the number of servings you need.

1 lb ground beef – The star of the dish, providing protein and flavor.
1 medium onion, chopped – Adds sweetness and depth to the ground beef.
2 cloves garlic, minced – Enhances the savory flavors of the casserole.
1 can (14.5 oz) diced tomatoes – Adds acidity and moisture to the dish.
1 can (8 oz) tomato sauce – Provides a smooth and rich base for the casserole.
2 cups cooked pasta (penne, elbow, or rotini work well) – Starches absorb the sauce and make the dish more filling.
1 cup shredded cheddar cheese – Melts on top for a golden, bubbly finish.
½ teaspoon salt – Season to taste.
¼ teaspoon black pepper – Adds a hint of heat and balance.
1 teaspoon Italian seasoning – A blend of herbs like oregano and basil to add depth.

Ingredients List for Ground Beef Casserole Variations

While the above ingredients create a delicious base, there are plenty of ways to switch things up to suit your taste. Here are some substitutions and add-ins you might want to try:

Substitute ground turkey or chicken for a leaner version.
Add chopped vegetables, like bell peppers, carrots, or zucchini, for extra nutrients.
Use cream of mushroom or cream of chicken soup instead of tomato sauce for a different flavor profile.
Swap out pasta for cooked rice or quinoa to change the texture and make the dish gluten-free.
Top with breadcrumbs or crushed crackers for a crispy finish.
Use mozzarella or Monterey Jack cheese for a different cheesy flavor.

Substitutions and Variations

One of the best things about casseroles is that they are endlessly adaptable. Whether you want to cater to dietary restrictions, use up ingredients you already have, or simply change the flavor profile, here are some great substitutions and variations you can try with your ground beef casserole:

Low-carb option: Swap out the pasta for riced cauliflower or zucchini noodles to make it keto-friendly.
Spicy variation: Add diced jalapeños, red pepper flakes, or hot sauce to give the casserole a little heat.
Dairy-free option: Omit the cheese and sour cream or use dairy-free alternatives to make this casserole vegan-friendly.
Vegetarian option: Swap the ground beef for plant-based meat or lentils for a protein-rich vegetarian version.
Mexican-inspired variation: Add taco seasoning to the beef, and swap out the Italian herbs for cumin and chili powder. Top with pepper jack cheese, and serve with salsa and guacamole.

Step-by-Step Cooking Instructions

Follow these step-by-step instructions to make a delicious ground beef casserole:

Preheat the oven: Set your oven to 375°F (190°C) so it’s ready to go once you assemble the casserole.
Cook the pasta: In a large pot of salted boiling water, cook the pasta until al dente according to package instructions. Drain and set aside.
Brown the beef: In a large skillet, cook the ground beef over medium heat until browned, about 5-7 minutes. Break up the meat as it cooks so that it crumbles into small pieces.
Add onions and garlic: Once the beef is browned, add the chopped onion and minced garlic to the skillet. Cook for an additional 3-4 minutes until the onions are soft and translucent.
Add tomatoes and sauce: Stir in the diced tomatoes, tomato sauce, salt, pepper, and Italian seasoning. Let the mixture simmer for about 5 minutes, allowing the flavors to meld together.
Combine with pasta: In a large bowl, mix the cooked pasta with the beef and tomato sauce mixture. Stir until everything is well combined.
Assemble the casserole: Spread the pasta and beef mixture evenly into a greased 9x13-inch baking dish. Spread the sour cream over the top in an even layer.
Top with cheese: Sprinkle the shredded cheddar cheese evenly over the casserole.
Bake: Place the casserole in the preheated oven and bake for 20-25 minutes, or until the cheese is melted and bubbly.
Cool and serve: Let the casserole cool for about 5 minutes before serving to allow it to set.

How to Cook Ground Beef Casserole: A Step-by-Step Guide

To make this recipe a success, here’s a recap of the most important steps you need to follow:

Step 1: Preheat your oven to 375°F.
Step 2: Cook your pasta until al dente and set aside.
Step 3: Brown the ground beef in a skillet over medium heat.
Step 4: Add onions and garlic, then stir in the diced tomatoes and tomato sauce.

Step 6: Spread everything in a greased baking dish, then top with sour cream and shredded cheese.
Step 7: Bake for 20-25 minutes until the casserole is hot and the cheese is melted.

Common Mistakes to Avoid

Avoid these common mistakes to make sure your ground beef casserole comes out perfectly:

Overcooking the pasta: Make sure to cook the pasta just until al dente, as it will continue to cook in the oven.
Skipping the seasoning: Don’t forget to season your beef mixture properly—bland ground beef will make for a boring casserole.
Not draining excess fat: If your ground beef is fatty, drain off any excess grease after browning. Too much oil can make the casserole greasy.
Burning the cheese: Keep an eye on your casserole as it bakes to avoid burning the cheese on top. If the cheese is browning too quickly, you can cover it with foil.

Serving and Presentation Tips

A well-presented casserole can be just as inviting as it is delicious. Here are some tips for serving and presentation:

Garnish with fresh herbs: A sprinkle of fresh parsley or basil on top of the casserole after it comes out of the oven will add color and brightness.
Serve with a side salad: A light green salad with a tangy vinaigrette will help balance out the richness of the casserole.
Use a shallow dish: A shallow casserole dish allows for more even baking and better presentation, with golden brown edges of cheese and pasta.

How to Serve Ground Beef Casserole

Once your ground beef casserole is out of the oven, it's time to serve it up. You can cut it into squares or simply spoon portions directly onto plates. Pair it with a crisp green salad, roasted vegetables, or garlic bread for a complete meal. You can also serve it with a side of sour cream or hot sauce for added flavor.

Presentation Ideas for Ground Beef Casserole

To elevate the presentation of your ground beef casserole, consider these ideas:

Use individual ramekins: Instead of a large baking dish, divide the mixture into smaller individual-sized ramekins or oven-safe dishes for a more elegant presentation.
Top with fresh vegetables: After baking, scatter sliced cherry tomatoes or diced avocado on top for a burst of color and freshness.
Layer the ingredients neatly: Take care when assembling the casserole so that each layer is even, making for a more visually appealing dish when served.
