1/4 cup tomato paste: Brings concentrated tomato richness and a lovely brick-red color.

How to Make Pumpkin Tomato Pasta Bake with Walnuts and Sage Recipe

Step 1: Cook the Pasta

Start by preheating your oven to 375ºF and bringing a large pot of generously salted water to a boil. Add your pasta and cook it until it is just shy of al dente — firm but without that raw bite. This is key because the pasta will finish cooking in the oven, absorbing all that luscious sauce.

Step 2: Toast the Walnuts and Sage

While the pasta cooks, melt butter in a large sauté pan over medium heat. Once it’s hot, toss in the finely chopped walnuts and fresh sage. Toast them for about 5 minutes until the walnuts develop a golden-brown, toasty aroma. A pinch of salt here helps draw out their flavor even more. Set this savory mixture aside for topping later.

Step 3: Sauté Mushrooms and Onion

Return the pan to medium heat and add olive oil. Sauté the sliced cremini mushrooms and chopped onion until soft and fragrant, about 7 to 8 minutes. This combination forms a luscious foundation for the sauce, bringing out natural sweetness and umami.

Step 4: Build the Sauce

Stir in the tomato paste, minced garlic, and crushed red pepper flakes, cooking for 2 to 3 minutes until the tomato paste caramelizes slightly and deepens in color. Then gradually add fresh spinach, stirring as it wilts down to an inviting green layer. Sprinkle in dried oregano, kosher salt, and black pepper to season perfectly.

Step 5: Combine Pumpkin and Cheese

Add vegetable broth to deglaze the pan, stirring up all the flavorful browned bits from the bottom. Then stir in pumpkin purée, Parmesan, and half a cup of fontina cheese. Keep stirring until the fontina melts into a smooth, creamy sauce. Mix in the drained pasta thoroughly, so every piece is generously coated in this pumpkin tomato delight.

Step 6: Bake to Perfection

Transfer your pasta and sauce mixture to a greased 13×9-inch baking dish. Sprinkle the remaining fontina cheese evenly on top, then scatter the buttery walnut and sage mixture over everything. Cover loosely with foil and bake for 15 minutes. Remove the foil and bake another 10 to 15 minutes until the cheese melts and develops a beautiful golden crust.

Garnishes

To make this dish even more special at the table, add a sprinkle of freshly chopped sage leaves or extra toasted walnuts on top for a burst of color and texture. A light drizzle of good-quality olive oil or a scattering of freshly grated Parmesan can also bring an elegant finish.

Side Dishes

Pair this warm, hearty bake with a crisp arugula salad tossed in lemon vinaigrette to cut through the creaminess. Garlic bread or toasted baguette slices are also fantastic for scooping up every last bit of the luscious sauce.

Make Ahead and Storage

Storing Leftovers

This pasta bake tastes just as delightful the next day. Let it cool completely before transferring leftovers to an airtight container and refrigerate for up to 3 days. The flavors meld beautifully as it rests, making it an ideal make-ahead meal.

Freezing

If you want to keep this delightful dish longer, freeze it in a freezer-safe container after baking and cooling. It will keep well for up to 2 months. When you’re ready to enjoy, thaw overnight in the fridge before reheating.

Reheating

To reheat, cover the pasta bake with foil to prevent drying out and warm in a preheated oven at 350ºF until bubbly and heated through, usually about 20 minutes. Microwaving works too for a quicker option, though the oven method helps maintain the dish’s fabulous texture.

FAQs

Can I use a different type of pumpkin or squash?

Absolutely! While canned pumpkin purée works best for a smooth consistency, you can use homemade or puréed butternut squash or kabocha squash for a slightly different but equally delicious flavor.

Is this recipe vegetarian or vegan?

This recipe is vegetarian but not vegan due to the cheese and butter. However, you can easily make it vegan by substituting dairy butter with a plant-based alternative and using vegan cheeses or nutritional yeast for a cheesy flavor.

What pasta shape is best for this bake?

Choose pasta shapes that can hold onto plenty of sauce, such as mezzi rigatoni, shells, ziti, fusilli, or farfalle. These tubular or ridged shapes help capture the creamy pumpkin tomato sauce in every bite.

Can I prepare the sauce ahead of time?

Yes! You can make the sauce and even cook the pasta a day ahead. Just combine and store them separately in the fridge. When ready, assemble the bake and heat as instructed for convenience without sacrificing flavor.

How spicy is the dish with the red pepper flakes?

The crushed red pepper flakes add just a gentle warmth, not overwhelming heat. You can adjust the amount to your preference or omit them entirely if you prefer a milder flavor profile.
