Cheesy Pasta Bake with Pumpkin Tomato Sauce tastes rich, cozy, and a little bit fancy, like mac and cheese went on a fall vacation to Italy. It works perfectly for busy weeknights or casual entertaining, and you can get it on the table in about 50 minutes. I tested versions of this for my own Sunday family dinners, and my kids now refer to it as “orange lasagna without the rules.”
Why You Should Try This Cheesy Pasta Bake with Pumpkin Tomato Sauce
This pasta bake gives you creamy, cheesy comfort with a subtle sweetness from pumpkin and a bright tang from tomato. The pumpkin sauce feels silky and luxurious, while the cheese pulls into those glorious strings that make everyone at the table weirdly quiet.
The recipe uses mostly pantry ingredients, so you can throw it together when the fridge looks sad. It also sneaks in pumpkin in a way that tastes indulgent, not “health food,” which makes picky eaters suspicious in the best possible way.

Ingredients You’ll Need
Pasta and cheeses
- 12 ounces short pasta
- Use rigatoni, penne, fusilli, or shells.
- Whole wheat or chickpea pasta also works if you like extra fiber or protein.
- 2 cups shredded low moisture mozzarella
- Pre-shredded works fine for busy nights, though block mozzarella melts a bit smoother.
- 1 cup shredded sharp cheddar
- Sharp cheddar adds flavor that stands up to the pumpkin.
- 1 cup grated Parmesan or Pecorino Romano
- Parmesan tastes milder and nuttier, Pecorino tastes saltier and punchier.
- 4 ounces cream cheese, softened
- This gives the pumpkin tomato sauce extra creaminess and body.
Pumpkin tomato sauce base
- 2 tablespoons olive oil
- 1 small yellow onion, finely chopped
- 3 cloves garlic, minced
- 1 teaspoon dried Italian seasoning
- 1 teaspoon smoked paprika
- 1 teaspoon dried thyme or sage
- 1 pinch red pepper flakes
- Adjust to taste if you like more heat.
- 1 cup canned pumpkin puree
- Use plain pumpkin puree, not pumpkin pie filling. Any store brand works.
- 1 can (14 to 15 ounces) crushed tomatoes or tomato sauce
- Crushed tomatoes give more texture, tomato sauce gives a smoother result.
- 1 tablespoon tomato paste
- Tube tomato paste works great and keeps well in the fridge.
- 1 cup vegetable or chicken broth
- Low sodium broth gives you more control over salt.
- 1/2 cup milk or half and half
- Whole milk tastes best, but any milk you have on hand works.
- 1 teaspoon sugar or maple syrup
- This balances the acidity of the tomatoes.
- Salt and black pepper to taste
Optional mix-ins
- 2 cups baby spinach or chopped kale
- 1 cup cooked Italian sausage or ground turkey
- 1 cup sautéed mushrooms or roasted vegetables
- 1/2 cup ricotta, dotted between layers for extra creaminess
Toppings
- Extra 1/2 cup shredded mozzarella
- Extra 1/4 cup grated Parmesan
- Fresh basil or parsley, chopped, for serving
Equipment
- Large pot for boiling pasta
- Large skillet or Dutch oven for the sauce
- 9×13 inch baking dish or similar casserole dish
- Colander
- Wooden spoon or spatula
- Whisk
- Measuring cups and spoons
- Foil to cover the dish while baking
Tips & Tricks
- Salt the pasta water generously so the pasta carries flavor into the bake.
- Undercook the pasta by 2 minutes so it finishes in the oven and stays al dente.
- Stir a splash of pasta cooking water into the sauce if it looks too thick.
- Taste the pumpkin tomato sauce before you add cheese and adjust salt, pepper, and heat.
- Use block cheese and shred it yourself if you want the smoothest melt.
- Add a handful of spinach or kale to the sauce near the end to sneak in greens.
- Grease the baking dish lightly so the cheesy edges release more easily.
- Cover the pasta bake with foil for the first part of baking so the cheese melts evenly.
- Remove the foil near the end so the top browns and turns bubbly.
- Let the pasta bake rest 5 to 10 minutes before serving so it sets slightly and slices more neatly.
How to Make Cheesy Pasta Bake with Pumpkin Tomato Sauce
Step 1: Boil the pasta
Bring a large pot of salted water to a boil. Add the pasta and cook it 2 minutes less than the package suggests. Stir occasionally so it does not stick. Drain the pasta and set it aside while you prepare the pumpkin tomato sauce.
Step 2: Sauté veggies and aromatics
Heat oil in a large stock pot or Dutch oven over medium heat. Once hot, add onions and carrots; cook until soft, about 8 minutes. Stir in garlic, ginger, harissa, coriander, and turmeric; cook 2 minutes, until aromatic. Season with salt.
Step 3: Build the pumpkin tomato sauce
Add the canned pumpkin puree, crushed tomatoes, and tomato paste to the pot with the aromatics. Stir until everything looks smooth and combined. Pour in the broth and bring the mixture to a gentle simmer over medium heat. Add Italian seasoning, smoked paprika, thyme or sage, red pepper flakes, sugar, salt, and pepper, then simmer 8 to 10 minutes so the flavors mingle.
Step 4: Make it creamy and cheesy
Lower the heat and stir in the milk or half and half. Add the cream cheese in small chunks and whisk until it melts into the pumpkin tomato sauce. Stir in half of the mozzarella, half of the cheddar, and half of the Parmesan until they melt and the sauce turns thick and glossy. Taste again and adjust seasoning so the sauce tastes slightly saltier than you want the final dish, since the pasta will mellow it.
Step 5: Combine pasta and sauce
Add the drained pasta directly into the pot of pumpkin tomato sauce. Stir until every piece of pasta wears a generous coat of sauce. Fold in any mix-ins you like, such as spinach, cooked sausage, or mushrooms. If the mixture looks very thick, add a splash of broth or milk to loosen it slightly.
Step 6: Layer in the baking dish
Preheat your oven to 375°F. Lightly grease a 9×13 inch baking dish. Spoon half of the cheesy pumpkin tomato pasta into the dish and spread it in an even layer. Sprinkle with a little of the remaining mozzarella, cheddar, and Parmesan, then add the rest of the pasta and top with all the remaining cheese.
Step 7: Bake until bubbly
Cover the baking dish loosely with foil so the cheese does not brown too quickly. Bake for 15 minutes, then remove the foil. Continue baking 10 to 15 minutes, until the top turns golden and the edges bubble. Let the Cheesy Pasta Bake with Pumpkin Tomato Sauce rest for about 10 minutes, then sprinkle with fresh basil or parsley and serve.
