Ingredients
- 450 g (1 lb) dry pasta of choice (such as mezzi rigatoni, shells, ziti or any other tubular pasta, fusilli, or farfalle)
- 30 g (2 Tbsp) unsalted butter
- 60 g (1/2 cup) finely chopped walnuts
- 10 g (2 Tbsp) finely chopped fresh sage leaves
- 30 ml (2 Tbsp) extra-virgin olive oil
- 225 g (8 oz) cremini (baby bella) mushrooms, sliced
- 1 medium yellow onion, finely chopped
- 60 g (1/4 cup) tomato paste
- 4 garlic cloves, minced
- 2.5 ml (1/2 tsp) crushed red pepper flakes (adjust to taste)
- 150-200 g (3 to 4 handfuls) fresh baby spinach
- 5 ml (1 tsp) dried oregano
- 5 g (1 tsp) kosher salt, plus more for pasta water
- 2.5 ml (1/2 tsp) freshly ground black pepper
- 1.25 ml (1/4 tsp) ground nutmeg
- 720 ml (3 cups) vegetable broth
- 425 g (15-oz) can pumpkin purée (100% pure pumpkin)
- 50 g (1/2 cup) freshly grated Parmesan cheese
- 150 g (1 1/2 cups) freshly grated fontina cheese, divided
Instructions
- Preheat your oven to 190°C (375°F). Lightly grease a 33×23 cm (13×9 inch) baking dish and set aside.
- Bring a large pot of generously salted water to a rolling boil. Add the pasta and cook for 2 minutes less than the package directions for al dente. This ensures the pasta remains firm enough to absorb the sauce and finish cooking without becoming mushy during the bake. The pasta should still be quite firm, though tender enough to bite through. Drain the pasta thoroughly into a colander and set aside.
- Meanwhile, melt the butter in a large sauté pan or Dutch oven over medium heat. Once the butter is shimmering, add the finely chopped walnuts and fresh sage. Cook for approximately 5 minutes, stirring occasionally, until the walnuts are fragrant and lightly toasted. This step infuses the butter with sage and brings out the nutty flavor of the walnuts. Season with a small pinch of salt, then transfer the mixture to a small bowl and set aside.
- Return the same sauté pan to medium heat. Add the extra-virgin olive oil, then introduce the sliced cremini mushrooms and finely chopped yellow onion. Sauté, stirring periodically, for 7 to 8 minutes, or until the mushrooms have released their moisture and the onions are soft and translucent.
- Stir in the tomato paste, minced garlic, and crushed red pepper flakes into the mushroom and onion mixture. Cook for 2 to 3 minutes, stirring constantly, allowing the tomato paste to caramelize slightly and deepen in color to a brick red hue. This caramelization intensifies its flavor. Gradually add the fresh baby spinach, stirring continuously until the greens wilt down. Finally, stir in the dried oregano, kosher salt, black pepper, and ground nutmeg, ensuring all spices are well incorporated.
- Pour in the vegetable broth, making sure to scrape up any browned bits stuck to the bottom of the pan with a wooden spoon or spatula. This step, known as deglazing, adds incredible depth of flavor to the sauce. Stir in the pumpkin purée, grated Parmesan cheese, and 75 g (1/2 cup) of the grated fontina cheese. Continue to stir gently until the fontina cheese has completely melted and the sauce is smooth and creamy. Add the par-cooked pasta to the pan and stir carefully until all the noodles are thoroughly coated in the rich pumpkin tomato sauce.
- Transfer the entire pasta mixture to the prepared 33×23 cm (13×9 inch) baking dish, spreading it evenly. Sprinkle the remaining 75 g (1 cup) of grated fontina cheese over the top, followed by the buttery walnut-sage mixture you prepared earlier. Loosely cover the baking dish with aluminum foil and bake for 15 minutes. Uncover the dish and continue baking for another 10 to 15 minutes, or until the cheese on top is beautifully melted, bubbly, and golden brown.
- Remove the pasta bake from the oven and let it rest for 5-10 minutes before serving. This brief resting period allows the sauce to set and makes for easier, cleaner serving.
Tools You’ll Need
- Large pot (for pasta)

- Wooden spoon or spatula
- Whisk
- 33×23 cm (13×9 inch) baking dish
- Cutting board
- Chef's knife

Essential Success Tips
- Do not overcook the pasta initially; it should be very al dente, as it will continue cooking in the oven and absorb more sauce.
- Take your time caramelizing the tomato paste; this step is crucial for developing deep, rich umami flavors in the sauce.
- Use 100% pure pumpkin purée, not pumpkin pie filling, which contains added sugar and spices.
- Freshly grated cheeses, especially fontina and Parmesan, melt more smoothly and offer superior flavor compared to pre-shredded varieties.
- Allow the pasta bake to rest for 5-10 minutes after baking; this helps the sauce set and prevents it from being too runny when served.
Professional Cooking Secrets
- To maximize the walnut flavor, briefly toast them in butter with the sage. The fat helps to extract and deepen their nutty essence, creating a more pronounced aroma and taste for the topping.
- The combination of tomato paste and pumpkin purée creates a 'umami bomb'. The acidity of the tomato brightens the earthy sweetness of the pumpkin, preventing the sauce from becoming too flat or overly sweet.
- Deglazing the pan with vegetable broth after sautéing the aromatics and tomato paste is essential. Those browned bits stuck to the bottom of the pan (fond) are packed with concentrated flavor that will enrich your sauce significantly.
Notes
- Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat gently in the oven or microwave.
- Make-Ahead: You can assemble the entire pasta bake (up to the point of baking) a day in advance. Cover tightly and refrigerate. Add an extra 10-15 minutes to the covered baking time if baking from cold.
- Variations: For a non-vegetarian option, brown 225 g (1/2 lb) Italian sausage or ground turkey with the mushrooms and onions. You can also experiment with other hard cheeses like Gruyère or white cheddar for different flavor profiles.
Frequently Asked Questions
Can I use fresh pumpkin instead of canned purée?
Yes, absolutely! You'll need to roast and purée your own pumpkin. About 450-500 g (1 lb) of roasted pumpkin flesh will yield roughly the amount needed for this recipe. Ensure it's very smooth before adding to the sauce.
What's the best type of pasta for a bake?
Tubular or ridged pasta shapes like mezzi rigatoni, ziti, or penne work wonderfully as they capture the sauce inside and on their surfaces. Shells or fusilli are also excellent choices for holding onto the rich sauce.
Can I freeze this pasta bake?
While it's best enjoyed fresh, you can freeze individual portions or the entire bake (unbaked or baked) for up to 1-2 months. If freezing unbaked, thaw overnight in the refrigerator before baking. If freezing baked, thaw and reheat, potentially covered with foil to prevent drying out.
