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

Step 1: Preheat & Cook Pasta
Preheat your oven to 375°F (190°C). In a large pot, bring salted water to a boil. Add your choice of dry pasta, cooking until it’s 2 minutes shy of al dente, about 8-10 minutes. Drain the pasta and set it aside, ensuring it retains some firmness for the bake.

Step 2: Prepare Walnut-Sage Topping
In a large sauté pan, melt 2 tablespoons of unsalted butter over medium heat. Once melted, add the finely chopped walnuts and 1 tablespoon of fresh sage. Sauté for about 5 minutes, or until the walnuts are fragrant and lightly toasted. Transfer the mixture into a bowl and set it aside for later.

Step 3: Sauté Vegetables
Using the same sauté pan, increase the heat to medium-high and add 2 tablespoons of extra-virgin olive oil. Once heated, toss in the sliced cremini mushrooms and finely chopped yellow onion. Sauté the mixture for about 8 minutes, or until the mushrooms have softened and the onions are translucent, releasing their natural sweetness.

Step 4: Build Flavor
Stir in ¼ cup of tomato paste, 4 minced garlic cloves, and ½ teaspoon of crushed red pepper flakes into the mushroom mixture. Cook for another 3-4 minutes, scraping the bottom of the pan to prevent sticking, until the tomato paste is caramelized and fragrant, enhancing the base of your pasta bake with pumpkin tomato sauce.

Step 5: Add Greens & Season
Gradually add 3-4 handfuls of fresh baby spinach into the sauté pan, stirring until wilted, which should take about 2-3 minutes. Then, sprinkle in 1 teaspoon of dried oregano, 1 teaspoon of kosher salt, ½ teaspoon of black pepper, and ¼ teaspoon of ground nutmeg. Mix well to evenly distribute the seasonings through the vegetables.

Step 6: Create the Sauce
Next, deglaze the pan by adding 3 cups of vegetable broth, scraping up any remaining bits stuck to the pan. Once combined, mix in 1 can (15 oz) of pumpkin purée and ½ cup of grated Parmesan cheese, followed by ½ cup of grated fontina cheese. Stir until everything is melted and well-combined, forming a rich sauce for your pasta bake with pumpkin tomato sauce.

Step 7: Combine With Pasta
Add your cooked pasta to the creamy sauce in the sauté pan, gently stirring until each piece is fully coated in the flavorful mixture. Ensure all components are incorporated well before transferring the contents into a greased 13×9-inch baking dish, laying a hearty foundation for your bake.

Step 8: Top & Bake
Sprinkle the remaining 1 cup of grated fontina cheese evenly over the pasta mixture in the baking dish. Then, top it with the walnut-sage mixture previously set aside. 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 melted and golden brown on top.

Sugar pumpkins are ideal for cooking as they have a sweet flavor and smooth texture. Always opt for fresh vegetables for the best taste in your cheesy pumpkin pasta bake!

What’s the best way to store leftovers of the cheesy pumpkin pasta bake?
Store any leftovers in an airtight container in the refrigerator for up to 5 days. Just make sure to let it cool completely beforehand. When you reheat, add a splash of vegetable broth to keep it creamy and prevent dryness. This helps maintain that lovely texture we all adore!

Can I freeze the cheesy pumpkin pasta bake?

When you’re ready to indulge again, thaw it overnight in the fridge, and reheat in the oven with a bit of broth added for moisture.

Why is my pasta bake too dry?
If your pasta bake turns out dry, it could be due to overcooking the pasta beforehand. It’s important to cook it just until it’s al dente, as it will continue to absorb moisture while baking.

I often make this dish with everyone’s needs in mind! It’s vegetarian-friendly and can easily be adapted for dairy-free diets by substituting the cheeses with nutritional yeast and using plant-based alternatives. If serving to pets, be cautious with garlic and onion as they can be harmful to them. Always check for nut allergies when adding walnuts or opting for substitutes like pecans or sunflower seeds.

Can I modify the vegetables in the cheesy pumpkin pasta bake?
Absolutely! The more the merrier! You can mix in any of your favorite vegetables such as zucchini, bell peppers, or even broccoli for added nutrition. Just make sure to consider the cooking time for these veggies; you want to maintain a slight crunch for the best bite!
