Ingredients You’ll Need

Here’s everything you need to make this delicious beef casserole. Nothing fancy—just real, simple ingredients.

Save

1 pound ground beef
1 small onion, diced
2 cloves garlic, minced
2 cups cooked pasta (or sliced potatoes if you prefer)
1 can cream of mushroom soup
1/2 cup sour cream
1 cup shredded cheddar cheese
1/2 cup mozzarella cheese
1 teaspoon salt
1/2 teaspoon black pepper
1 teaspoon paprika (optional but tasty)
1 tablespoon olive oil
1/2 cup beef broth
Fresh parsley for garnish (optional but makes you look fancy)

FYI: You probably already have half of these in your kitchen.

Step-by-Step Instructions

1. Preheat the Oven Preheat your oven to 375°F (190°C).
Yes, actually do it now. Don’t skip this step thinking it will magically heat faster later. Preheating matters.

2. Cook the Beef Heat olive oil in a large skillet over medium heat. Add the diced onion and cook for about 2 minutes until it softens. Add the ground beef and cook until browned. Break it apart with a spatula as it cooks. Toss in the garlic and cook for another minute until fragrant. Drain excess grease if needed.

3. Make the Creamy Sauce

In a bowl, mix together:

Cream of mushroom soup
Sour cream
Beef broth
Salt
Pepper
Paprika

Stir until smooth. This creamy mixture is what gives the casserole its rich, comforting flavour.

4. Combine Everything Add the cooked pasta to the beef mixture in the skillet. Pour the creamy sauce over everything and stir well. Make sure every bite gets coated in that delicious sauce.

5. Assemble the Casserole Transfer the mixture into a greased baking dish. Spread it evenly. Sprinkle cheddar and mozzarella cheese generously on top. Don’t be shy here—cheese is not the place to practice self-control.

6. Bake to Perfection Place the dish in the oven and bake for 20–25 minutes until the cheese melts and turns bubbly and golden. Your kitchen will smell incredible by this point.

7. Garnish and Serve Remove from the oven and let it rest for about 5 minutes before serving. Sprinkle fresh parsley on top if you want to look like a professional chef. Or don’t. It’ll taste amazing either way.

Common Mistakes to Avoid

Even simple recipes have a few traps. Let’s dodge them like pros.

Skipping the preheat
Seriously, don’t do this. The casserole cooks unevenly if the oven isn’t hot enough.
Overcooking the pasta
Cook it just until al dente. It continues cooking in the oven.
Not draining the beef
Too much grease makes the casserole oily. Nobody wants that.
Using too little cheese
Look, this is a casserole. Cheese is basically the law.
Serving it immediately
Give it a few minutes to rest or it’ll fall apart like a dramatic soap-opera character.

Alternatives & Substitutions

One of the best things about casseroles? They’re flexible.

Ground turkey instead of beef
Want something lighter? Turkey works great.
Different cheeses
Try Monterey Jack, Colby, or even pepper jack if you want a little kick.
Add vegetables
Bell peppers, mushrooms, spinach, or peas fit perfectly in this dish.
Swap pasta for potatoes
Thin sliced potatoes turn this into a more traditional casserole vibe.

IMO, casseroles are basically “clean out the fridge” recipes. If it tastes good together, it works.
