How to Make Homestyle Ground Beef Casserole Recipe
Step 1: Prepare the Baking Dish and Cook the Beef
Start by preheating your oven to 350°F and greasing a 9×13-inch baking dish; this ensures nothing sticks and cleanup is a cinch. Next, in a large skillet over medium heat, cook the ground beef along with the diced onion until the beef is nicely browned and the onion turns tender, usually about 6 to 8 minutes. Once browned, drain off any excess fat so your casserole won’t be greasy. Add the minced garlic and sauté for another minute to release that wonderful aroma.
Step 2: Build the Flavorful Sauce
Stir in the tomato sauce, drained diced tomatoes, Italian seasoning, salt, and black pepper right into the beef mixture. Let this simmer gently for 5 to 7 minutes so all those flavors can mingle and deepen. This step is where your homemade taste really starts to shine.
Step 3: Combine with Pasta and Sour Cream
Remove the skillet from heat, then fold in the cooked pasta and sour cream. The sour cream is key here—it makes the dish creamy and luscious without being heavy, coating every bite just right.
Step 4: Assemble and Bake
Pour the beef and pasta mixture evenly into the prepared baking dish. Generously sprinkle the shredded cheddar and mozzarella cheeses across the top to create a golden, bubbly, cheesy crust once baked. Slide the casserole into the oven and bake uncovered for 20 to 25 minutes, or until you see the cheese melted, bubbly, and lightly golden—this is when the dish reaches its peak comfort food status.
Step 5: Garnish and Serve
Allow the casserole to cool for a few minutes after baking, then sprinkle with freshly chopped parsley if you like a bit of herbaceous brightness. Serve warm and get ready for some serious compliments!
How to Serve Homestyle Ground Beef Casserole Recipe

Garnishes
A sprinkle of chopped parsley is a simple way to add color and freshness that balances the richness of the casserole. You can also add a dash of grated Parmesan or a few red pepper flakes if you want an added layer of flavor or some subtle heat.
Side Dishes
To round out this satisfyingly filling dish, pair it with a crisp green salad or steamed vegetables like broccoli or green beans. Their freshness and slight crunch will complement the creamy, cheesy texture perfectly, balancing out the meal.
Creative Ways to Present
If you want to impress guests or simply make dinner feel more special, serve the casserole in individual ramekins or small cast-iron skillets. This adds a charming personal touch and makes the cheesy top layer look even more inviting.
Make Ahead and Storage
Storing Leftovers
Leftovers of this Homestyle Ground Beef Casserole Recipe can be stored tightly covered in the refrigerator for up to 3 days. The flavors deepen overnight, making the next day’s meal just as delicious, if not better!
Freezing
If you want to prep in advance or save some for a later date, this casserole freezes beautifully. Freeze it before baking in an airtight container or covered tightly with foil and a plastic layer. It will keep well for up to 3 months and can be baked straight from frozen with a slight increase in cooking time.
Reheating
For reheating, cover the casserole with foil to prevent it from drying out and warm it in a 350°F oven until heated through, about 20 minutes. You can also microwave individual portions, but the oven helps maintain that lovely, melty cheese texture.
FAQs
Can I use a different type of pasta?
Absolutely! While elbow macaroni or rotini work great because they hold the sauce well, feel free to use shells, penne, or even bowtie pasta—any shape that captures bits of beef and sauce works wonderfully.
Is it possible to make this recipe vegetarian?
You can substitute the ground beef with plant-based crumbles or cooked lentils for a meat-free version. Keep the seasonings and cheese the same to keep the essence of this Homestyle Ground Beef Casserole Recipe intact.
Can I add vegetables to the casserole?
Definitely! Chopped bell peppers, spinach, or mushrooms are fantastic additions that add nutrition and extra flavor. Just sauté them with the onions or mix them into the casserole before baking.
What kind of cheese works best for this casserole?
The combination of sharp cheddar and mild mozzarella gives you a perfect balance of flavor and meltiness. You can experiment by adding Parmesan for a nuttier edge or Monterey Jack for extra creaminess.
How do I prevent the casserole from drying out?
Make sure to cover the casserole with foil if baking for longer than recommended or during reheating to keep moisture locked in. Also, the sour cream in the mix helps keep the casserole creamy and prevents dryness.
