Cheesy Penne Ground Beef

My family’s go-to comfort food is this Cheesy Penne Ground Beef casserole, a hearty Italian-American bake that’s both simple and satisfying. It combines penne pasta with a rich ground beef sauce and three types of cheese for that irresistible golden crust. I’ve made this for busy weeknights and casual gatherings alike because it always delivers on flavor without requiring fancy techniques. The aroma as it bakes is enough to gather everyone around the table, eager for a scoop.

Ingredients You’ll Need

• Penne pasta: Its shape catches the sauce and cheese for maximum flavor in every forkful. Cook it al dente so it holds up during baking.
• Olive oil: Sautéing the onions and garlic in olive oil builds a flavorful foundation for the entire dish.
• Yellow onion: Chopped finely and cooked until soft, it adds a subtle sweetness that balances the savory beef.
• Garlic: Fresh minced garlic gives that essential aromatic punch that makes the sauce taste homemade.
• Ground beef (80/20): This blend browns up juicy and flavorful, forming the hearty base of the casserole.
• Marinara sauce: A good jarred sauce saves time but still delivers a rich, tomatoey base. Choose one you love.
• Dried oregano: This classic Italian herb adds earthy depth to the sauce when simmered.
• Dried basil: Dried basil infuses the sauce with a sweet, herbal note that’s perfect for baking.
• Red pepper flakes: Just a pinch adds a hint of warmth that elevates all the other flavors.
• Salt: Seasons every component, from the pasta water to the beef, ensuring everything tastes balanced.
• Black pepper: Freshly ground pepper adds a sharp, aromatic kick that cuts through the richness.
• Shredded mozzarella: The key to that iconic, stretchy, bubbly cheese topping we all crave.
• Grated Parmesan: Adds a salty, nutty complexity and helps create a golden-brown crust on top.
• Ricotta cheese: Optional dollops create creamy pockets that make the casserole extra luxurious and satisfying.
• Fresh basil: Torn and scattered on top after baking, it adds a fresh, peppery finish.
• Additional Parmesan: Serving extra on the side lets everyone customize their cheesy goodness.

How to Make It

Cook the Pasta:
Bring a large pot of salted water to a boil and cook the penne until it’s al dente, which usually takes about 10 to 12 minutes. Draining it right after cooking prevents it from getting mushy, and setting it aside lets it stop cooking so it holds its shape in the bake.

Sauté the Aromatics:
Heat the olive oil in a large skillet over medium heat, then add the chopped onion. Sauté it until it’s soft and translucent, which takes about five minutes, because this sweetness forms the base of your sauce. Stir in the minced garlic and cook for just one more minute until fragrant, being careful not to let it burn.

Brown the Ground Beef:
Add the ground beef to the skillet with the onions and garlic, breaking it up with a wooden spoon as it cooks. You’ll want to cook it until it’s no longer pink, about seven to ten minutes, and then drain off any excess fat if you prefer a leaner sauce.

Simmer the Sauce:
Stir in the jar of marinara sauce, dried oregano, dried basil, red pepper flakes if you’re using them, salt, and black pepper. Let everything simmer on low heat for ten minutes so the flavors have a chance to meld together beautifully.

Preheat and Combine:
While the sauce simmers, preheat your oven to 375°F so it’s ready when you are. In a large mixing bowl, combine the drained pasta, the beef sauce, one cup of the mozzarella, and half a cup of the Parmesan. If you’re using ricotta, dollop it in and gently fold everything together until it’s evenly mixed.

Assemble the Casserole:
Transfer the pasta mixture to a 9×13 inch baking dish and spread it out into an even layer. Top it with the remaining mozzarella and Parmesan cheeses, covering the surface completely for that iconic golden crust.

Bake to Perfection:
Place the casserole in the preheated oven and bake for 20 to 25 minutes. You’ll know it’s done when the cheese is completely melted, bubbly, and has those tempting golden-brown spots on top.

Rest and Serve:
Take the casserole out of the oven and let it rest for about five minutes before diving in. This short wait allows the flavors to settle and makes serving much easier. Garnish with torn fresh basil and extra Parmesan if you like.

Storage Tips

Store any leftovers in an airtight container in the fridge, where they’ll stay good for up to three days. Reheating is best done in a 350°F oven until warmed through, which keeps the texture from getting soggy, though the microwave works in a pinch. If you want to freeze it, assemble the casserole without baking, wrap it tightly with foil and plastic wrap, and it’ll keep for about three months. Just thaw it overnight in the fridge before baking as directed, adding a few extra minutes to the cooking time.

Ingredient Substitutions

If you don’t have penne, any short pasta like rigatoni or ziti will work just as well. For the ground beef, you can swap in ground turkey or Italian sausage for a different flavor profile. No marinara? Use crushed tomatoes seasoned with a pinch of sugar and extra herbs. If you’re out of mozzarella, provolone or a Mexican blend will still melt beautifully, and for Parmesan, Asiago or Romano make great salty substitutes. Skip the ricotta if you prefer, or use cottage cheese blended smooth for a similar creamy effect.

Serving Suggestions

This casserole is hearty enough to stand alone, but I always pair it with something fresh like a Caesar salad or steamed green beans to balance the plate. Garlic bread is a must for mopping up the cheesy sauce, and if you’re feeding a crowd, a side of roasted vegetables works wonderfully. For drinks, a light red wine like Pinot Noir complements the beef and tomatoes, or try sparkling water with lemon for a refreshing non-alcoholic option.

Cultural Context

This Cheesy Penne Ground Beef casserole is a quintessential example of Italian-American home cooking, born from the tradition of combining pasta with meat sauce and baking it with cheese. It echoes dishes like baked ziti or lasagna but simplifies the process for weeknight ease. The use of jarred marinara speaks to the modern, time-saving approach while still honoring the flavor foundations of Southern Italian cuisine. In many households, similar casseroles are the centerpiece of Sunday suppers and potlucks, representing comfort and community. It’s a dish that adapts to what’s in the pantry, reflecting the resourceful spirit of immigrant kitchens that created so many beloved fusion foods.
