Ingredient Notes & Details

Ground Beef
Use lean ground beef for less grease, but regular beef works too—just be sure to drain the fat. You can substitute ground turkey or chicken for a lighter version, or use Italian sausage for extra flavor.

Pasta
Elbow macaroni, rotini, or penne hold up best to baking. Use gluten-free pasta if needed. Cook just to al dente so it doesn’t soften too much in the oven.

Onion & Garlic
These build the flavor foundation. Fresh is best, but dehydrated onion and garlic powder will do in a pinch.

Tomato Sauce or Marinara
Choose your favorite jarred sauce or use your homemade blend. A robust sauce gives the casserole that classic, oven-roasted beef flavor. For a richer dish, mix in a spoon of tomato paste.

Cream Cheese or Sour Cream
This adds creaminess and helps bind everything together. Greek yogurt works as a substitute for extra protein.

Cheddar or Mozzarella Cheese
You want a good melting cheese. Cheddar gives sharpness, mozzarella gives stretchiness, and a blend of both delivers the ultimate cheesy beef casserole finish.

Seasonings
Salt, pepper, paprika, Italian seasoning, and a touch of onion powder bring the flavors to life. You can add red pepper flakes if you like heat.

Optional Vegetables
Bell peppers, mushrooms, spinach, peas, or zucchini can all be mixed in to make the casserole heartier and more nutritious.

Step-by-Step Instructions

Brown the ground beef
Heat a large skillet over medium-high heat. Add the ground beef and break it apart with a wooden spoon. Cook until fully browned and no pink remains. Drain excess fat for a cleaner flavor.

Add onions, garlic, and seasoning
Stir in diced onions and crushed garlic. Cook until softened. Add salt, pepper, Italian seasoning, and paprika. You want the mixture to smell fragrant and savory.

Stir in the sauce
Pour in your tomato or marinara sauce. Let it simmer for a few minutes to thicken slightly and absorb the seasonings. This helps build the signature richness of the casserole.

Cook the pasta
In a separate pot, cook pasta until just al dente. It will finish cooking in the oven, so don’t overcook it. Drain and set aside.

Combine the creamy layer
In a bowl, mix cream cheese or sour cream until smooth. This creamy layer adds depth and tenderness to each bite.

Assemble the casserole
In a large baking dish, start with a thin layer of sauce. Add half the pasta, half the beef mixture, and dollops of the creamy mixture. Repeat the layers and finish with shredded cheese on top.

Bake until bubbly
Bake at 350°F (175°C) for about 20–25 minutes, or until the cheese melts into a golden, irresistible layer. Let it rest for 10 minutes before serving so the structure sets.
