Pasta Bake with Pumpkin Tomato Sauce Ingredients

For the Pasta Bake

Dry Pasta (1 lb.) – Choose mezzi rigatoni, ziti, or fusilli for perfect texture in your pasta bake with pumpkin tomato sauce.
Butter (2 Tbsp.) – Adds a creamy richness; feel free to substitute with olive oil if you’re looking for a dairy-free option.
Cremini Mushrooms (8 oz., sliced) – Lend an earthy umami flavor; white mushrooms work perfectly if crimini aren’t available.
Yellow Onion (1, finely chopped) – The flavor base that elevates the dish; shallots can be swapped for a milder onion taste.
Garlic (4 cloves, minced) – A fragrant backbone of flavor for this pasta bake.
Fresh Baby Spinach (3-4 handfuls) – A nutritious boost; consider incorporating kale for a different texture.
Vegetable Broth (3 cups) – Adds moisture and depth; chicken broth can be a great alternative if you’re not vegetarian.
Pumpkin Purée (1, 15-oz. can) – The star of the dish, creating the creamy sauce; fresh pumpkin can be used if prepared properly.
Dried Oregano (1 tsp.) – Infuses an herby essence that complements the other flavors.
Kosher Salt (1 tsp.) – Essential seasoning to enhance all the flavors.
Black Pepper (1/2 tsp.) – Adds depth; adjust to your taste.

For the Cheese Sauce

Grated Parmesan Cheese (1/2 cup) – Brings in a rich, umami boost; nutritional yeast is a suitable substitute for a vegan option.
Grated Fontina Cheese (1 1/2 cups, divided) – Offers a melty creaminess; Gruyere or mozzarella will work well if you’d like to switch it up.

For the Walnut-Sage Topping

Walnuts (1/2 cup, finely chopped) – Provides delightful crunch and nuttiness; feel free to substitute with pecans if desired.
Fresh Sage (1 Tbsp. + 2 tsp., finely chopped) – Enhances the earthy notes; if unavailable, dried sage can be used, just remember to use less.

For the Spice Kick

Crushed Red Pepper Flakes (1/2 tsp.) – Adds a touch of heat to the dish; omit for a milder version.
Ground Nutmeg (1/4 tsp.) – Balances the sweetness of the pumpkin beautifully; cinnamon can serve as an alternative if needed.

Step‑by‑Step Instructions for Cheesy Pumpkin Pasta Bake

Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). Meanwhile, bring a large pot of salted water to a boil on the stove. This step is crucial as it prepares the base for your Cheesy Pumpkin Pasta Bake, ensuring the pasta cooks perfectly before being combined with that creamy pumpkin tomato sauce.

Step 2: Cook the Pasta
Once the water is boiling, add your dry pasta and cook it for about 8-10 minutes, or until it’s just 2 minutes shy of al dente. Drain the pasta and set it aside in a large bowl. This brief cooking time allows your pasta to maintain its shape and texture in the oven while absorbing the delicious flavors of the sauce.

Step 3: Toast the Walnut-Sage Mixture
In a large skillet, melt 2 tablespoons of butter over medium heat. Once melted, add the finely chopped walnuts and 1 tablespoon of fresh sage. Cook this mixture for about 5 minutes, stirring occasionally, until the walnuts are lightly toasted and fragrant. Transfer the mixture to a bowl and set it aside for later.

Step 4: Sauté the Vegetables
Using the same skillet, add 2 tablespoons of extra-virgin olive oil, along with sliced cremini mushrooms and chopped onion. Sauté for approximately 8 minutes, stirring frequently until the mushrooms are softened and the onions are translucent. This step builds the base flavor for your Cheesy Pumpkin Pasta Bake.

Step 5: Incorporate Tomato Paste and Seasonings
Next, add 1/4 cup of tomato paste, minced garlic, and 1/2 teaspoon of crushed red pepper flakes to the skillet. Cook this mixture for about 3-4 minutes, stirring continuously until the tomato paste darkens and becomes aromatic. This adds a vibrant depth to your pumpkin tomato sauce.

Step 6: Add Spinach and Seasoning
Gradually stir in the fresh baby spinach until it wilts, which should take about 2-3 minutes. Then, season with 1 teaspoon of dried oregano, 1 teaspoon of kosher salt, 1/2 teaspoon of black pepper, and 1/4 teaspoon of ground nutmeg. These spices elevate the flavor profile of the sauce, making your pasta bake even more delicious.

Step 7: Create the Pumpkin Sauce
Pour 3 cups of vegetable broth into the skillet to deglaze, scraping up any browned bits. Then stir in 1 can (15 oz.) of pumpkin purée, 1/2 cup of grated Parmesan cheese, and 1/2 cup of grated Fontina cheese. Cook this mixture on low heat until combined and smooth, creating a creamy base for your Cheesy Pumpkin Pasta Bake.

Step 8: Combine Pasta and Sauce
Now, carefully fold in the cooked pasta, ensuring every piece is thoroughly coated with the flavorful pumpkin sauce. This step ensures that each bite of your pasta bake is packed with rich flavor and creaminess, setting the stage for a comforting and homely meal.

Step 9: Assemble the Pasta Bake
Transfer the pasta mixture into a greased 13×9-inch baking dish, spreading it out evenly. Sprinkle the remaining 1 cup of grated Fontina cheese over the top, followed by the walnut-sage mixture. This delicious topping adds both crunch and flavor, perfectly complementing the creamy pasta beneath.

Step 10: Bake to Perfection
Cover the baking dish with aluminum foil and bake your Cheesy Pumpkin Pasta Bake in the preheated oven for 15 minutes. After that time, remove the foil and bake for an additional 10 minutes. You’ll know it’s done when the cheese is melty and golden, creating a beautiful, bubbly crust.

Make Ahead Options

Preparing the Cheesy Pumpkin Pasta Bake in advance is a game-changer for meal prep enthusiasts! You can make the entire dish up to 24 hours ahead by assembling it in your baking dish and covering it tightly with foil. For optimal flavor, refrigerate it until ready to bake. You can also prep the walnut-sage topping and store it separately for up to 3 days to keep it crunchy. When you’re ready to serve, simply remove the dish from the refrigerator, let it sit at room temperature for about 30 minutes, and then bake as directed. This way, your pasta bake with pumpkin tomato sauce remains just as delicious while saving you precious time on busy weeknights!
