Ingredients

• 1 pound ground beef
• 12 ounces penne pasta
• 1 jar (24 ounces) marinara sauce
• 1 cup sour cream
• 2 cups shredded mozzarella cheese
• 1 cup shredded cheddar cheese
• 1 small onion, finely chopped
• 2 cloves garlic, minced
• 1 teaspoon Italian seasoning
• ½ teaspoon salt
• ¼ teaspoon black pepper
• 1 tablespoon olive oil

How to Make Creamy Cheesy Baked Penne Beef Casserole

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C). Lightly grease a 9-by-13-inch baking dish and set it aside.

Step 2: Cook the Penne

Bring a large pot of salted water to a boil. Cook the penne according to the package instructions, but drain it about 1–2 minutes before it reaches full tenderness. The pasta will finish cooking in the oven.

Drain well and set aside.

Step 3: Brown the Beef

Heat the olive oil in a large skillet over medium heat. Add the chopped onion and cook for 3–4 minutes until softened. Add the ground beef and cook, breaking it into small pieces, until browned and no pink remains.

Drain any excess grease. Stir in the garlic and Italian seasoning, cooking for about 30 seconds until fragrant.

Step 4: Add the Marinara Sauce

Pour the marinara sauce into the skillet with the beef. Add the salt and black pepper, then stir to combine. Let the sauce simmer gently for 3–5 minutes to blend the flavors.

Remove the skillet from the heat.

Step 5: Make It Creamy

Place the cooked penne in a large bowl. Add the sour cream and about half of the mozzarella cheese, stirring gently until the pasta is coated.

Pour in the beef and marinara mixture, then toss everything together until evenly combined.

Step 6: Assemble the Casserole

Transfer the pasta mixture to the prepared baking dish. Spread it into an even layer, then sprinkle the remaining mozzarella and all the cheddar cheese over the top.

Step 7: Bake Until Golden

Cover the dish loosely with foil and bake for 15 minutes. Remove the foil and continue baking for another 10–15 minutes, until the cheese is melted, bubbling, and lightly golden around the edges.

For a more golden top, broil for 1–2 minutes at the end, watching carefully to prevent burning.

Step 8: Rest and Serve

Let the casserole rest for about 5–10 minutes before serving. This gives the sauce time to settle and makes the portions easier to scoop.

Tips for the Best Baked Penne Casserole

• Undercook the pasta slightly: Penne that is a little firm before baking holds its shape better.
• Drain the beef: Removing excess grease keeps the sauce from becoming oily.
• Use freshly shredded cheese: It often melts more smoothly than pre-shredded cheese.
• Keep the casserole moist: If your marinara sauce is especially thick, stir in a small splash of pasta water before baking.
• Let it rest: A short resting period helps the creamy sauce cling to the pasta.

Easy Variations

• Add vegetables: Stir in sautéed mushrooms, spinach, or diced bell peppers.
• Make it extra cheesy: Add a little grated Parmesan to the topping.
• Use a different meat: Ground turkey or Italian sausage can replace the ground beef.
• Add some heat: Sprinkle in red pepper flakes for a gentle spicy kick.

What to Serve with Creamy Cheesy Baked Penne

This casserole pairs wonderfully with garlic bread, toasted baguette slices, Caesar salad, or steamed broccoli. A simple green salad with a tangy dressing also balances the rich, cheesy sauce.

Storage and Reheating

Store cooled leftovers in an airtight container in the refrigerator for 3–4 days.

To reheat, place a portion in a microwave-safe dish and heat until steaming hot. For larger portions, cover the casserole with foil and warm it in a 350°F (175°C) oven. Add a spoonful of water or marinara sauce if the pasta seems dry.

To freeze, place the cooled casserole in a freezer-safe container and freeze for up to 2–3 months for best quality. Thaw overnight in the refrigerator before reheating.

Frequently Asked Questions

Can I make this casserole ahead of time?

Yes. Assemble the casserole, cover it, and refrigerate it for up to 24 hours before baking. If baking straight from the refrigerator, allow extra time and check that the center is thoroughly hot.

Can I use another pasta shape?

Absolutely. Rigatoni, ziti, or rotini work well because their shapes hold the sauce.

Why should I undercook the penne?

The pasta continues to absorb sauce and soften in the oven. Draining it slightly early helps prevent a mushy casserole.

Can I make it without sour cream?

Yes. Plain Greek yogurt can be used as a substitute, although it may give the sauce a slightly tangier flavor.
