Easy Pasta Bakes For A Crowd – Creamy 45-Minute Dinner

Pasta Bakes For A Crowd is a practical solution when you need to feed six or more without slaving over multiple pots. This recipe layers penne, a rich tomato-cream sauce, and a blend of mozzarella and Parmesan, then bakes until bubbling and golden. It's a complete meal that's perfect for weeknight family dinners, potlucks, or casual gatherings.

The key to a great pasta bake is balance: a sauce that clings to the pasta, a topping that crisps without burning, and a bake time that melds flavors without drying out. Here, I've tested the exact ratios and timings so you get a consistent result every time. You can prep it ahead, freeze it, or double it for a larger crowd—this recipe scales cleanly.

I'll walk you through each step, from cooking the pasta to the final broil, with exact temperatures and doneness cues. You'll also get substitution tips for the cheese and pasta, plus storage and reheating guidance. This is comfort food engineered for reliability.

About the Ingredients

1 lb (450g) penne pasta

Use rigatoni or ziti if preferred. For a gluten-free option, use brown rice penne and cook 2 minutes less.

2 tbsp (30ml) olive oil

Extra virgin for flavor, but any neutral oil works. Substitute with butter for a richer taste.

1 medium yellow onion, finely chopped (about 1 cup)

Sweet onion or shallots can be used. If short on time, use 1 tsp onion powder.

3 cloves garlic, minced

Fresh garlic is best, but 1 tsp garlic powder can substitute in a pinch.

1 lb (450g) ground beef (85% lean)

Ground turkey or Italian sausage work well. For a vegetarian version, use 1 lb mushrooms, chopped.

1 can (28 oz / 800g) crushed tomatoes

Use fire-roasted for extra depth. If you have whole peeled tomatoes, crush them by hand.

1 cup (240ml) heavy cream

Half-and-half or whole milk can be used for a lighter sauce, but the bake will be less creamy.

1 tsp dried oregano

Fresh oregano: use 1 tbsp chopped. Or substitute with Italian seasoning.

1/2 tsp red pepper flakes (optional)

For heat; omit if serving kids. Adjust to taste.

1 tsp salt, plus more for pasta water

Kosher salt preferred. Sea salt works too.

1/2 tsp black pepper

Freshly ground for best flavor.

2 cups (200g) shredded mozzarella cheese

Low-moisture mozzarella melts best. Pre-shredded works, but block cheese shreds creamier.

1/2 cup (50g) grated Parmesan cheese

Pecorino Romano can substitute for a sharper flavor.

Tips & Tricks

• Cook pasta 2 minutes less than package directions: it will finish cooking in the oven, preventing mushiness.
• Use a 9×13-inch baking dish for even baking. If doubling, use two dishes or a larger roasting pan.
• Let the bake rest 5-10 minutes after removing from oven to set, making serving cleaner.
• If the top browns too quickly, cover loosely with foil for the remaining bake time.

Step-by-Step Instructions

1. Preheat and prep

Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or nonstick spray. Bring a large pot of salted water to a boil.

2. Cook the pasta

Add penne to boiling water and cook for 8 minutes (or 2 minutes less than package directions). Drain, but do not rinse; set aside. The pasta will finish cooking in the oven.

3. Brown the meat

In a large skillet over medium-high heat (350°F/175°C), heat olive oil. Add onion and cook until translucent, about 3 minutes. Add garlic and cook 30 seconds. Add ground beef, breaking it up, and cook until browned, about 5-7 minutes. Drain excess fat if necessary.

4. Make the sauce

Stir in crushed tomatoes, heavy cream, oregano, red pepper flakes (if using), salt, and pepper. Bring to a simmer, then reduce heat to low and cook for 5 minutes to meld flavors.

5. Combine and assemble

In a large bowl, combine the cooked pasta and meat sauce. Mix well. Transfer to the prepared baking dish and spread evenly.

6. Top with cheese

Sprinkle the shredded mozzarella and Parmesan evenly over the top. Ensure full coverage for a golden crust.

7. Bake until bubbly

Bake uncovered at 375°F (190°C) for 25 minutes, or until edges are bubbling and the top is golden brown. If you want extra browning, switch to broil for 2-3 minutes, watching carefully.

8. Rest and serve

Let the bake rest for 5-10 minutes before serving. This allows it to set and makes serving easier. Garnish with fresh parsley if desired.

Delicious Variations

Vegetarian

Substitute ground beef with 1 lb (450g) chopped mushrooms and add 1 cup (150g) frozen spinach, thawed and squeezed dry.

Spicy Sausage

Use 1 lb (450g) Italian sausage (casings removed) instead of beef, and increase red pepper flakes to 1 tsp.

Cheesy Alfredo

Replace crushed tomatoes with 2 cups (480ml) Alfredo sauce and add 1 cup (100g) cooked broccoli florets.
