How to Make Ground Beef Casserole Recipe
Step 1: Prepare Your Oven and Baking Dish
Start by preheating your oven to 375°F and giving your 9×13-inch baking dish a light greasing. This simple step ensures your casserole bakes evenly and doesn’t stick, making cleanup a breeze afterward.
Step 2: Cook the Ground Beef and Aromatics
In a large skillet over medium heat, brown the ground beef with diced onion until the beef is fully cooked and the onion turns soft and translucent, about 6 to 8 minutes. This combo forms the flavorful backbone of your casserole.
Step 3: Add Garlic, Seasoning, and Tomato
Stir in the minced garlic, salt, pepper, and Italian seasoning, letting them cook together for an additional minute so all those fragrant aromas get released. Then, add in the tomato sauce and drained diced tomatoes, allowing the mixture to simmer for 5 minutes so the flavors blend perfectly.
Step 4: Combine Pasta and Sour Cream
In a large bowl, mix your cooked pasta with the creamy sour cream for a smooth, rich coating that will marry beautifully with the beef mixture. This step makes the casserole ultra-moist and velvety.
Step 5: Bring It All Together
Fold the beef and tomato mixture into the pasta and sour cream bowl, stirring gently until everything is evenly combined. Spread this hearty mixture into your prepared baking dish and top it generously with both cheddar and mozzarella cheeses for that irresistible golden crust.
Step 6: Bake to Perfection
Bake uncovered for 20 to 25 minutes, until the cheese is melted, bubbly, and slightly golden around the edges. Let it cool just a bit before serving to ensure those layers settle and every bite is just right.
How to Serve Ground Beef Casserole Recipe

Garnishes
A sprinkle of freshly chopped parsley adds a pop of color and a hint of herbal freshness that brightens the dish beautifully. You can also add a few red pepper flakes for some subtle heat, or a drizzle of good olive oil for a glossy finish.
Side Dishes
This casserole pairs wonderfully with a crisp green salad tossed in a light vinaigrette to cut through the richness. Garlic bread or simple steamed vegetables like broccoli or green beans round out the meal with vibrant bites and texture contrast.
Creative Ways to Present
For a fun twist, serve individual portions in small ramekins topped with a dollop of sour cream and chopped chives. You could even layer the casserole in clear glass dishes for a stunning view of the colorful layers, perfect for dinner parties or special occasions.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer any leftover Ground Beef Casserole Recipe to an airtight container and refrigerate. It will stay fresh for up to 3 days and actually tastes even better as the flavors continue to meld.
Freezing
This recipe freezes like a dream. Assemble in a freezer-safe dish but don’t bake; cover tightly and freeze for up to 3 months. When ready, thaw overnight in the fridge and bake as instructed, adding a few extra minutes to ensure it’s heated through evenly.
Reheating
Reheat individual servings in the microwave until warmed through or cover the casserole with foil and warm in a 350°F oven for about 15 to 20 minutes. Adding a sprinkle of extra cheese before reheating can revive that freshly baked glow.
FAQs
Can I use ground turkey or chicken instead of beef?
Absolutely! Ground turkey or chicken are excellent lean alternatives that keep the casserole lighter but still tasty. You might want to add a bit more seasoning since poultry has a milder flavor.
Is it okay to use other types of pasta?
Yes, feel free to swap in your favorite pasta shapes like rotini, fusilli, or shells. Just be sure to cook them al dente since they’ll soften further during baking.
Can I make this casserole gluten-free?
Definitely! Use gluten-free pasta and double-check that your canned tomatoes and seasonings don’t contain gluten. This way, the dish stays inclusive and just as delicious.
What can I add to make it more vegetable-packed?
Great question! Toss in cooked spinach, chopped bell peppers, zucchini, or mushrooms with the beef for extra nutrients and flavor. This makes the recipe more colorful and nutritious without losing any comfort.
Can I substitute Greek yogurt for sour cream?
Yes, Greek yogurt works wonderfully as a tangy, lighter alternative. It enhances creaminess while reducing fat, making your Ground Beef Casserole Recipe a bit healthier without sacrificing taste.

This Ground Beef Casserole Recipe truly shines as a family favorite that’s easy to make and endlessly satisfying.
