Pasta Bake with Pumpkin Tomato Sauce
For the Pasta
- 1 lb. dry pasta of choice – This is the base of your dish; substitute with gluten-free pasta if preferred.
For the Sauce
- 2 Tbsp. butter – Adds richness to the sauce; use olive oil for a dairy-free option.
- 1/4 cup tomato paste – Enhances sauce flavor and color; can be replaced with pureed canned tomatoes if needed.
- 4 garlic cloves, minced – Provides aromatic flavor; garlic powder can be used for convenience.
- 1/2 tsp. crushed red pepper flakes – Adds a kick of heat; omit for a milder version.
- 3 cups vegetable broth – Liquid for the sauce base; chicken broth works for a non-vegetarian alternative.
- 1 (15-oz.) can pumpkin purée – Key ingredient providing creaminess and nutrition; butternut squash puree can be a great substitute.
For the Vegetables
- 8 oz. cremini (baby bella) mushrooms – Adds umami flavor; can be swapped with button mushrooms.
- 1 yellow onion, finely chopped – Adds sweetness and depth; shallots can be a suitable replacement.
- 3-4 handfuls fresh baby spinach – Brings vibrant color and nutrition; kale works well if you prefer.
For the Cheese

- 1 1/2 cups grated fontina cheese, divided – Creates a creamy texture for the bake; mozzarella makes a good substitute for melting.
For the Topping
- 1/2 cup finely chopped walnuts – Provides crunch and earthy flavor; pecans are an excellent alternative if desired.
- 1 Tbsp. + 2 tsp. finely chopped fresh sage leaves – Adds a fragrant herbaceous note; dried sage can be used in smaller amounts.
Seasoning
- 1 tsp. dried oregano – Offers Italian herb flavor; thyme or basil can also be used.
- 1 tsp. kosher salt – Enhances overall flavor; adjust according to dietary needs.

Step‑by‑Step Instructions for Cheesy Pumpkin Pasta Bake with Savory Walnut-Sage Topping
Step 1: Preheat the Oven
Begin by preheating your oven to 375ºF (190ºC). This ensures it’s hot enough to create a perfectly baked crust on your Cheesy Pumpkin Pasta Bake once it’s ready to go in. Make sure your baking dish is greased and waiting on the counter to streamline the process.
Step 2: Cook the Pasta
In a large pot, bring salted water to a rolling boil, then add your dry pasta. Cook the pasta until just under al dente, about 2 minutes shy of package instructions. This prevents mushiness during baking. Drain the pasta and set it aside while you whip up the creamy pumpkin tomato sauce.
Step 3: Toast the Walnuts
In a sauté pan, melt the butter over medium heat, then add the chopped walnuts and 1 tablespoon of fresh sage. Toast the walnuts for about 3-4 minutes until fragrant and golden, stirring frequently. Once toasted, transfer the mixture to a bowl and set it aside, making room for your next step.
Step 4: Sauté the Vegetables
In the same sauté pan, heat the extra-virgin olive oil over medium heat. Add the finely chopped mushrooms and onion, sautéing for about 8 minutes until the onions are translucent and the mushrooms are soft. Stir occasionally to avoid sticking, ensuring a rich, aromatic base for your sauce.
Step 5: Build the Sauce
Stir in the tomato paste, minced garlic, and crushed red pepper flakes into the sautéed vegetables. Cook for another 3-4 minutes, stirring often, until the tomato paste caramelizes and deepens in flavor. You should see a beautiful color change, filling your kitchen with a rich aroma.
Step 6: Add the Greens and Seasonings
Gradually incorporate the fresh spinach, stirring it into the sauté mixture until wilted. Next, add the oregano, kosher salt, black pepper, and ground nutmeg. Mix thoroughly to ensure even seasoning throughout your sauce, infusing it with warmth and depth perfect for your Cheesy Pumpkin Pasta Bake.
Step 7: Create the Sauce Base
Pour the vegetable broth into the pan to deglaze, scraping up any flavorful bits stuck to the bottom. Then, add the pumpkin purée and half of the grated Parmesan and fontina cheeses, stirring until everything is well combined and smooth. Your creamy sauce is now ready!
Step 8: Combine Pasta and Sauce
In a large mixing bowl, combine the cooked pasta with the pumpkin sauce. Gently mix until the pasta is completely coated with the luscious sauce. This is where the flavors meld beautifully, creating the hearty base for your delicious Cheesy Pumpkin Pasta Bake.
Step 9: Assemble the Bake
Transfer the pasta and sauce mixture into the greased baking dish, spreading it evenly. Top with the remaining grated fontina cheese and the walnut-sage mixture you prepared earlier. This will form a lovely crust that adds flavor and texture once baked.
Step 10: Bake to Perfection
Cover the baking dish with foil and place it in the oven for 15 minutes. After that, remove the foil and bake for an additional 10 minutes or until the top is golden and bubbly. You’ll know it’s done when the cheese is melted and the edges are lightly crisped – heaven!
Step 11: Let it Rest
Once baked to perfection, remove your Cheesy Pumpkin Pasta Bake from the oven and let it sit for about 5 minutes. This waiting time allows the flavors to settle and makes for easier serving. You’ll want that perfect slice to present to your family or friends!
Step 12: Serve and Enjoy
Spoon out generous portions of your delicious Cheesy Pumpkin Pasta Bake with Savory Walnut-Sage Topping onto plates. Pair it with a simple green salad or some crusty bread for a complete fall meal that’s bursting with flavor and coziness.
