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 salted water to boil. Cook your pasta of choice until just shy of al dente—this means the pasta should still have a bit of firmness because it will continue cooking in the oven. Drain and set the pasta aside while you prepare the rest of the ingredients.

Step 2: Toast Walnuts and Sage

Next, melt butter in a large sauté pan over medium heat. Add the finely chopped walnuts and sage leaves, toasting them gently for about 5 minutes until they release their aroma and walnuts become golden brown. A pinch of salt helps enhance these flavors. Once done, transfer this flavorful mixture to a small bowl to keep it separate as a garnish later.

Step 3: Sauté Mushrooms and Onions

Return the pan to the heat and add olive oil. Toss in sliced cremini mushrooms and chopped onion. Cook them for 7 to 8 minutes, stirring occasionally until they soften and develop lovely caramelized edges. This stage builds the savory backbone for the sauce.

Step 4: Build the Sauce Base

Stir in tomato paste, minced garlic, and crushed red pepper flakes to the mushrooms and onions. Let everything cook for 2 to 3 minutes until the tomato paste darkens and caramelizes slightly, adding a rich depth. Gradually add the fresh baby spinach handful by handful, stirring to let it wilt evenly into the mix. Season with oregano, salt, and pepper to create a well-rounded flavor profile.

Step 5: Combine Pumpkin and Cheese

Pour in the vegetable broth, scraping the pan’s bottom to lift any sumptuous browned bits. Then stir in the pumpkin purée along with the Parmesan cheese and half of the fontina cheese. Keep stirring the sauce gently until the fontina melts fully, producing a smooth, creamy sauce that perfectly curls around the pasta when combined.

Step 6: Assemble and Bake

Fold the cooked pasta into the sauce until each piece is thoroughly coated. Transfer this mixture to a greased 13×9-inch baking dish. Sprinkle the remaining fontina cheese on top followed by the toasted walnut and sage mixture. Cover loosely with foil and bake for 15 minutes. Then remove the foil and bake 10 to 15 more minutes, allowing the cheese to bubble and turn a gorgeous golden brown.

For that extra touch, sprinkle fresh sage leaves or chopped walnuts on top once the pasta bake is out of the oven. A drizzle of good-quality extra-virgin olive oil or a light dusting of Parmesan cheese adds a lovely finish that will have everyone reaching for seconds.

Side Dishes

This pasta bake pairs wonderfully with a crisp simple green salad dressed in a lemon vinaigrette, which cuts through the dish’s richness beautifully. You can also serve it alongside some crusty bread or garlic focaccia to mop up every last bit of that luscious sauce.

Make Ahead and Storage

Storing Leftovers

Leftovers keep well in an airtight container in the refrigerator for up to 4 days. The flavors deepen overnight, making it even tastier the next day. Just be sure to cover it tightly so it doesn’t dry out.

Freezing

You can freeze portions of this pasta bake once fully cooled. Wrap tightly in freezer-safe containers or heavy-duty foil and freeze for up to 2 months. When ready, thaw overnight in the fridge before reheating.

Reheating

Reheat leftovers gently in the oven at 350ºF, covered with foil, until warmed through. Alternatively, microwave single servings on medium power, stirring halfway to ensure even heating without drying the dish out.

FAQs

Can I use other types of cheese instead of fontina?

Absolutely! Mozzarella, provolone, or even a mild cheddar can work well here. Choose cheeses that melt easily and complement the creamy texture of the pumpkin sauce.

Is it necessary to use fresh sage, or can I use dried?

Fresh sage provides a brighter, more pronounced flavor and a lovely texture. If you only have dried sage, reduce the amount since it’s more concentrated, but fresh is definitely recommended for this recipe.

Can I substitute the pumpkin purée with butternut squash?

Yes, roasted and pureed butternut squash makes a fantastic alternative, offering a similar sweet, nutty flavor that pairs beautifully with the tomato and sage.

Is this recipe suitable for vegetarians?

This dish is naturally vegetarian, and using vegetable broth keeps it so. Just double-check your cheese to ensure it’s made with vegetarian-friendly rennet if that’s important to you.

Can I make this recipe vegan?

Definitely! Swap butter for a plant-based alternative, use vegan cheese or nutritional yeast for a cheesy flavor, and substitute the Parmesan with a vegan version. Just ensure your vegetable broth is vegan too.
