Step‑by‑Step Instructions for Cheesy Pumpkin Pasta Bake with Mushrooms and Spinach
Step 1: Preheat the Oven
Start by preheating your oven to 375ºF (190ºC) so it’s hot and ready to bake the Cheesy Pumpkin Pasta Bake. This step is essential to ensure that the dish cooks evenly, resulting in a golden, bubbling cheese topping. Meanwhile, gather your ingredients and cookware, including a large pot, a skillet, and a 13×9-inch baking dish.
Step 2: Cook the Pasta
In a large pot of salted boiling water, cook your pasta of choice—mezzi rigatoni, shells, or ziti—for about 2 minutes less than the package directions for al dente. Drain the pasta and set it aside, knowing it will continue cooking in the oven as part of the pasta bake. This technique ensures perfect texture in your Cheesy Pumpkin Pasta Bake.
Step 3: Prepare Walnut-Sage Topping
In a skillet over medium heat, melt 2 tablespoons of unsalted butter, watching for a foamy appearance. Add the finely chopped walnuts and 1 tablespoon of sage, stirring to combine. Cook for about 5 minutes until the walnuts are toasted and fragrant. This crunchy topping adds a delightful contrast to the creamy pasta bake—set aside once done.
Step 4: Sauté Vegetables
Next, in the same skillet, add 2 tablespoons of extra-virgin olive oil along with the sliced cremini mushrooms and finely chopped onion. Cook for approximately 8 minutes, stirring occasionally until the vegetables are softened and starting to caramelize. This step builds a rich flavor base for your sauce in the Cheesy Pumpkin Pasta Bake.
Step 5: Build the Sauce
Stir in 1/4 cup of tomato paste, minced garlic, and 1/2 teaspoon of red pepper flakes to the sautéed vegetables. Cook this mixture for about 2-3 minutes until the tomato paste begins to caramelize, giving your sauce depth. Gradually add fresh spinach, letting it wilt before mixing in the remaining sage, 1 teaspoon of oregano, salt, pepper, and a splash of vegetable broth to deglaze the skillet.
Step 6: Combine with Cheese
Once all the flavors are beautifully melded, stir in 1 can of pumpkin purée, 1/2 cup grated Parmesan cheese, and 1/2 cup of the grated Fontina cheese until the sauce is smooth and creamy. This luscious mixture becomes the heart of your Cheesy Pumpkin Pasta Bake, embracing all the comforting flavors of fall.
Step 7: Mix with Pasta
In a large mixing bowl, combine the creamy sauce with your cooked pasta, ensuring every piece is evenly coated. This step is crucial for delivering the delicious flavors throughout the dish. Once combined, transfer the mixture to your greased 13×9-inch baking dish, spreading it out evenly for consistent cooking.
Step 8: Assemble and Bake
Top the pasta bake with the reserved Fontina cheese and the walnut-sage mixture. Cover the dish with foil and bake in the preheated oven for 15 minutes. After that, remove the foil and continue baking for an additional 10 minutes, or until the cheese is golden and bubbly. Allow the Cheesy Pumpkin Pasta Bake to rest for a few minutes before serving, so the cheesy layers settle and it’s easier to scoop.

Make Ahead Options
These Cheesy Pumpkin Pasta Bake with Mushrooms and Spinach is perfect for meal prep enthusiasts! You can prepare the creamy pumpkin sauce and sauté the vegetables up to 24 hours in advance; simply refrigerate them in an airtight container to maintain their freshness. The pasta can also be pre-cooked and stored separately to avoid it becoming mushy. When you’re ready to enjoy the dish, combine the sauce and pasta in your baking dish, top with cheese and walnut-sage mixture, and bake as directed. This way, you’ll have a comforting meal ready to go with minimal effort on busy weeknights!

Cheesy Pumpkin Pasta Bake Recipe FAQs
How do I choose the right pumpkin for the pasta bake?
Absolutely! For the best flavor, I recommend using canned pumpkin purée, preferably 100% pumpkin (look for it on the label). If you opt for fresh pumpkin, select a sugar pumpkin or pie pumpkin, which is sweeter and has a smoother texture. Be sure to cook and purée it before adding it to your dish, as it requires more preparation than canned.
How should I store leftovers of the cheesy pumpkin pasta bake?
Very simple! Allow the Cheesy Pumpkin Pasta Bake to cool slightly, then transfer it to an airtight container. It can be stored in the refrigerator for up to 5 days. This dish tends to taste even better the next day as the flavors meld, giving you a delightful second round of cozy comfort.
Can I freeze the cheesy pumpkin pasta bake?
Yes, you can! To freeze, let the pasta bake cool completely and then transfer it to a freezer-safe container. It can be frozen for up to 3 months. To reheat, simply thaw it overnight in the refrigerator and then warm it in the oven at 350ºF (175ºC) for about 20-25 minutes until heated through. This method maintains that creamy texture we all love!
What should I do if my pasta is too sticky after cooking?
If your pasta turns out sticky, it could be because it was overcooked or didn’t have enough salt in the water. Ensure you cook it just shy of al dente and toss it in a drizzle of olive oil after draining to prevent sticking. You can also try tossing the pasta with a little extra sauce before layering it, which helps keep it moist!
Is this cheesy pumpkin pasta bake suitable for pets?
While this dish is safe for humans, it’s not ideal for pets due to its rich ingredients, including spices and cheese that can upset their stomachs. Always check with your vet before sharing human food with pets, and if they’re around, perhaps set aside some plain cooked pasta or veggies as a tasty treat for them!
Are there any common allergies I should be aware of?
Absolutely! This recipe contains dairy (butter, cheeses), nuts (walnuts), and gluten (pasta). If you’re looking to accommodate dietary restrictions, you can make it nut-free by substituting the walnuts with sunflower seeds or simply omitting them. For gluten-free needs, swap in gluten-free pasta—it’s a delicious alternative!
