Ingredients
Method
- Preheat and prep: Heat the oven to 375°F (190°C). Grease a 9x13-inch baking dish with nonstick spray or butter.
- Cook the pasta: Bring a large pot of salted water to a boil. Cook the pasta to just shy of al dente, 1–2 minutes less than package directions.Drain and set aside.
- Brown the beef: In a large skillet over medium-high heat, warm the olive oil. Add the ground beef and cook, breaking it up with a spoon, until browned and no longer pink. Season with a pinch of salt and pepper, then drain excess fat if needed.
- Sauté aromatics: Add the diced onion to the beef and cook until softened, 3–4 minutes.Stir in the garlic and cook 30 seconds, just until fragrant.
- Build the sauce: Stir in the tomato sauce, drained diced tomatoes, Italian seasoning, smoked paprika, and red pepper flakes if using. Simmer 5–7 minutes to let flavors meld. Taste and adjust salt and pepper.
- Make it creamy: Turn off the heat and fold in the sour cream until the sauce looks creamy and smooth.This gives the casserole a rich, tangy base that won’t dry out.
- Combine with pasta: Add the cooked pasta to the skillet and toss to coat evenly. If the skillet is too full, mix everything together in a large bowl.
- Layer and top: Pour the mixture into the prepared baking dish. Sprinkle the shredded cheese evenly over the top.For extra flavor, add a pinch of black pepper over the cheese.
- Bake: Place the dish on the center rack and bake for 18–22 minutes, until the cheese is melted, bubbly, and lightly golden around the edges.
- Rest and serve: Let the casserole rest 5–10 minutes. This helps it set for cleaner slices. Garnish with chopped parsley or chives and serve warm.

Benefits of This Recipe
- Budget-friendly: Uses affordable staples like ground beef, pasta, and canned tomatoes.
- Balanced comfort: Protein, carbs, and a bit of dairy make it hearty and satisfying.
- Meal prep hero: Stores well and reheats without getting mushy when you undercook the pasta slightly.
- Customizable: Easy to adapt for picky eaters or to fit what’s in your pantry.
- Great for gatherings: Feeds a crowd and travels well for potlucks or family dinners.
What Not to Do
- Don’t overcook the pasta: It will keep cooking in the oven and can turn soft and gummy.
- Don’t skip seasoning: Taste the sauce and adjust salt, pepper, and herbs. Bland sauce means a bland casserole.
- Don’t use super lean beef without fat: A little fat equals flavor and moisture.
If using very lean beef, add a spoon of olive oil.
- Don’t bake it uncovered for too long: Overbaking dries it out. Pull it when the cheese is melted and bubbly.
- Don’t forget to rest: Slicing right away can make it messy. A short rest helps it set.
Variations You Can Try
- Tex-Mex twist: Swap Italian seasoning for chili powder and cumin.
Use pepper jack and cheddar, and add corn and black beans.
- Veggie boost: Stir in sautéed bell peppers, mushrooms, spinach, or zucchini. Roast the veggies first for extra flavor.
- Creamy Alfredo style: Replace tomato sauce with a light Alfredo and add broccoli florets. Top with mozzarella and Parmesan.
- Low-carb option: Use roasted cauliflower florets or zucchini noodles instead of pasta.
Drain well to avoid excess moisture.
- Italian classic: Add a handful of mini pepperoni or cooked Italian sausage. Finish with fresh basil and a dusting of Parmesan.
- Extra cheesy: Mix half the cheese into the pasta and sauce, then add the rest on top for pockets of gooey goodness.
FAQ
Can I use a different meat?
Yes. Ground turkey, chicken, or Italian sausage work well.
If using poultry, add a little extra olive oil and boost the seasoning to keep the flavor rich.
What cheese melts best for this casserole?
Mozzarella and mild cheddar melt beautifully. For more flavor, mix in Monterey Jack, provolone, or a little sharp cheddar. Freshly shredded cheese melts better than pre-shredded.
Do I have to use sour cream?
No.
Plain Greek yogurt is a great substitute that adds the same creamy tang. You can also use cream cheese (softened) whisked into the warm sauce.
How can I make it spicier?
Add extra red pepper flakes, a diced jalapeño with the onion, or stir in a spoonful of adobo sauce from chipotle peppers. Pepper jack cheese also adds a nice kick.
Can I assemble it ahead and bake later?
Absolutely.
Assemble, cover, and refrigerate up to 24 hours. Bake straight from the fridge, adding 5–10 minutes to account for the cold start.
What’s the best pasta shape?
Short shapes that hold sauce are ideal: rotini, fusilli, penne, shells, or elbows. They trap the sauce and keep every bite cheesy and satisfying.
How do I prevent a watery casserole?
Drain the diced tomatoes well and don’t over-simmer the sauce.
If adding vegetables, sauté or roast them first to cook off excess moisture.
Can I make it gluten-free?
Yes. Use your favorite gluten-free pasta and check labels on canned sauces. Cook the pasta just until al dente to avoid mushiness.

This cheesy ground beef casserole is everything you want on a busy night: easy to make, big on comfort, and reliably delicious.
