Step‑by‑Step Instructions for Cheesy Pumpkin Pasta Bake with Walnut-Sage Topping
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This temperature is perfect for achieving a golden, bubbly cheese topping on your cheesy pumpkin pasta bake, making it irresistibly inviting. Ensure your oven is fully heated before placing the dish inside, as this will help everything cook evenly.
Step 2: Cook the Pasta
Bring a large pot of salted water to a boil. Add your dry pasta and cook until it is just 2 minutes shy of al dente, typically around 8-10 minutes. This prevents the pasta from becoming mushy during baking. Drain the pasta well in a colander and set it aside, letting the steam escape while you prepare the sauce.
Step 3: Prepare the Walnut-Sage Topping
In a sauté pan over medium heat, melt 2 tablespoons of butter. Add the finely chopped walnuts and sage, cooking for about 5 minutes, or until the mixture is fragrant and the nuts are lightly toasted. When done, transfer this crunchy topping to a bowl and set it aside, allowing the flavors to meld.
Step 4: Sauté the Vegetables
Using the same sauté pan, add 2 tablespoons of olive oil and turn the heat to medium-high. Sauté the chopped onion and sliced mushrooms for 7-8 minutes, until they are softened and slightly caramelized. Stir often until they achieve a nice golden color, adding depth to your cheesy pumpkin pasta bake.
Step 5: Create the Flavor Base
Stir in 1/4 cup of tomato paste, 4 minced garlic cloves, and 1/2 teaspoon of crushed red pepper flakes into the sautéed vegetables. Continue cooking for 2-3 minutes, allowing the mixture to caramelize slightly, which will enhance its flavor. This aromatic base is crucial for the deliciousness of your pumpkin tomato sauce.
Step 6: Add the Greens and Seasoning
Now, add 3 to 4 handfuls of fresh baby spinach to the pan, stirring until it wilts. Season this mixture with 1 teaspoon of dried oregano, 1 teaspoon of kosher salt, 1/2 teaspoon of black pepper, and 1/4 teaspoon of ground nutmeg. Take a moment to enjoy the vibrant colors and inviting aromas that fill your kitchen.
Step 7: Prepare the Pumpkin Sauce
Deglaze the pan by pouring in 3 cups of vegetable broth. Then, mix in a 15-ounce can of pumpkin purée, 1/2 cup of grated Parmesan cheese, and 1/2 cup of grated Fontina cheese. Stir everything together until you have a smooth, creamy sauce. The combination of pumpkin and tomato will impart a lovely richness to your cheesy pumpkin pasta bake.
Step 8: Combine the Pasta and Sauce
Fold the drained pasta into your pumpkin sauce mixture, ensuring each piece is well-coated. The sauce will envelop the pasta beautifully, making it ready for baking. After mixing thoroughly, transfer everything into a greased 13×9-inch baking dish, spreading it out evenly for baking.
Step 9: Add Toppings and Bake
Sprinkle the remaining 1 cup of Fontina cheese over the pasta bake, followed by the walnut-sage topping. Cover the dish with aluminum foil and place it in the preheated oven. Bake for 15 minutes, then remove the foil and bake for an additional 10-15 minutes, until the top is golden and bubbling, showcasing the comforting layers beneath.
Step 10: Serve and Delight
Once baked to perfection, allow your cheesy pumpkin pasta bake to sit for a few minutes before serving. The aroma will draw everyone to the table, ready to enjoy this hearty dish. This warming meal makes for a perfect gathering centerpiece, rich in flavor and heartwarming comfort.

Cheesy Pumpkin Pasta Bake Recipe FAQs
How do I choose the right pumpkin for my pasta bake?
Absolutely! When selecting pumpkin, look for a firm and heavy one with a smooth, unblemished skin. Avoid any with dark spots, as these may indicate rot. Canned pumpkin purée is also a fantastic option for ease, providing consistent flavor and texture.
How can I store leftover cheesy pumpkin pasta bake?
You can store any leftovers in an airtight container and keep them in the fridge for up to 5 days. Just make sure to let the dish cool before sealing it. When reheating, you can use the microwave or oven until it’s warmed through, but I suggest the oven to retain the texture.
Can I freeze the pumpkin pasta bake?
Definitely! To freeze the dish, first, allow it to cool completely. Then, transfer it to a freezer-safe container, leaving some space for expansion. It can be stored for up to 3 months. When you’re ready to enjoy it, thaw it in the refrigerator overnight and reheat in the oven at 350°F (175°C) until heated through, which usually takes about 20-25 minutes.
What should I do if my pasta seems too dry after baking?
If you find the pasta bake dry, it may be due to overcooking or not enough sauce. In this case, you can stir in a bit of vegetable broth or cream before baking, ensuring the pasta stays moist. It’s always a good idea to keep an eye on the pasta texture while baking, and a good sauce-to-pasta ratio can help with that comforting consistency.
Is this recipe suitable for those with nut allergies?
Very! If you’re hosting someone with nut allergies, you can easily omit walnuts from the topping or replace them with a crispy topping made from breadcrumbs for crunch. Just remember to use a nut-free alternative to keep it safe for those with allergies.
Can I make the cheesy pumpkin pasta bake vegan?
Yes, indeed! To make it vegan, replace the butter with olive oil, use nutritional yeast instead of Parmesan, and choose plant-based milk to achieve the creamy texture. Also, ensure you select vegan pasta to keep it entirely plant-based. Enjoy your creamy dish without compromising on flavor!
