Step‑by‑Step Instructions for Cheesy Pumpkin Pasta Bake with Mushrooms and Spinach

Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures that the Cheesy Pumpkin Pasta Bake cooks evenly and achieves a golden, bubbly top. While the oven warms up, gather your ingredients and equipment, such as a large pot for boiling pasta and a baking dish for assembling the pasta bake.

Step 2: Cook the Pasta
In a large pot, bring salted water to a rolling boil. Add your choice of dry pasta and cook until it’s 2 minutes shy of al dente, about 6-8 minutes depending on the pasta. Keep an eye on it to prevent overcooking, then drain the pasta and set it aside in a colander, allowing the steam to escape while you prepare the sauce.

Step 3: Toast the Walnuts and Sage
Melt 2 tablespoons of unsalted butter in a sauté pan over medium heat. Once melted, add ½ cup of finely chopped walnuts and 1 tablespoon plus 2 teaspoons of finely chopped fresh sage. Toast the mixture for about 5 minutes, stirring occasionally until fragrant. Season with salt and pepper, then transfer this crunchy topping to a bowl and set aside.

Step 4: Sauté the Vegetables
In the same sauté pan, drizzle in 2 tablespoons of extra-virgin olive oil. Add 8 ounces of sliced cremini mushrooms and 1 finely chopped yellow onion. Cook this mixture over medium heat for about 8 minutes, or until the mushrooms are tender and the onions are translucent. Stir frequently to ensure even cooking and avoid burning.

Step 5: Build the Flavor Base
Stir ¼ cup of tomato paste, 4 minced garlic cloves, and ½ teaspoon of crushed red pepper flakes into the sautéed vegetables. Cook for 3-4 minutes, allowing the tomato paste to caramelize slightly, which enhances the sauce’s depth and flavor. Keep stirring until all the ingredients blend beautifully together.

Step 6: Add Spinach and Seasonings
Slowly fold in 3 to 4 handfuls of fresh baby spinach until completely wilted, which should take about 2 minutes. Once wilted, stir in 1 teaspoon of dried oregano, 1 teaspoon of kosher salt, ½ teaspoon of black pepper, and ¼ teaspoon of ground nutmeg. Ensure everything is well-mixed, releasing the aromatic autumnal flavors into your Cheesy Pumpkin Pasta Bake.

Step 7: Create the Pumpkin Sauce
Deglaze the pan by gradually adding 3 cups of vegetable broth into the mixture, scraping any delicious bits off the bottom. Stir in 1 (15-oz.) can of pumpkin purée, ½ cup of grated Parmesan cheese, and ½ cup of grated fontina cheese until the sauce is smooth and creamy. Allow it to simmer on low for a couple of minutes to meld the flavors.

Step 8: Combine Pasta with the Sauce
Fold the drained pasta into the creamy pumpkin sauce, ensuring that every noodle is luxuriously coated. This step is crucial for creating that delightful texture in the finished Cheesy Pumpkin Pasta Bake. Mix thoroughly, and be gentle to avoid breaking the pasta.

Step 9: Assemble the Pasta Bake
Transfer the coated pasta mixture to a greased baking dish, spreading it evenly. Sprinkle the remaining 1 cup of grated fontina cheese on top, ensuring it covers the surface well. Next, evenly distribute the walnut-sage topping over the cheese for added crunch and flavor.

Step 10: Bake to Perfection
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 15 minutes, then remove the foil and continue baking for an additional 10 minutes. Keep an eye on it as it bakes, aiming for a golden, bubbly top that indicates your Pasta Bake with Pumpkin Tomato Sauce is ready to serve.

Cheesy Pumpkin Pasta Bake with Mushrooms and Spinach Recipe FAQs

How do I choose the right pumpkin for the pasta bake?
Absolutely! When selecting pumpkin for this dish, opt for canned pumpkin purée, as it offers a smooth texture and convenient use. If using fresh pumpkin, choose a sugar pumpkin (or pie pumpkin) for sweetness and creaminess. Look for ones that feel heavy for their size, and avoid any with soft spots or blemishes.

What’s the best way to store leftovers of the pasta bake?
Very! To store leftovers, allow the Cheesy Pumpkin Pasta Bake to cool completely, then transfer it to an airtight container. It can stay fresh in the fridge for up to 5 days. To ensure the best flavor, I recommend eating it within the first few days, as the flavors intensify.

Can I freeze this pumpkin pasta bake for later?
Absolutely! Freeze the pasta bake for up to 3 months. For freezing, let it cool entirely before transferring it to airtight containers or freezer bags. Make sure to label the containers with the date and the dish name for easy identification. To reheat, thaw overnight in the fridge, then bake at 350°F (175°C) for 20-25 minutes until heated through.

My pasta came out mushy; how can I prevent this in the future?
Absolutely! To prevent mushy pasta in your Cheesy Pumpkin Pasta Bake, cook the pasta only to about 2 minutes shy of al dente. This way, it will retain a firm bite during baking. Additionally, stirring the pasta gently when combining with sauce helps maintain its integrity.

Is there an alternative to walnuts for the topping?
Absolutely! If you’re looking for alternatives to walnuts, breadcrumbs work well and provide a crunchy texture. For a nut-free option, try using crushed crackers or a blend of seeds like pumpkin or sunflower seeds. Just ensure to check for any allergies if serving to guests.

Is the recipe suitable for vegetarians or those with allergies?
Definitely! This Cheesy Pumpkin Pasta Bake is vegetarian-friendly, featuring rich flavors and plenty of nutritious ingredients.
