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

Step 1: Preheat and Cook Pasta
Begin by preheating your oven to 375ºF (190ºC). In a large pot, bring salted water to a boil, then add 1 lb of dry pasta. Cook until the pasta is 2 minutes shy of al dente, which should take about 8-10 minutes. Drain the pasta and set it aside, allowing it to cool slightly while you prepare the sauce.

Step 2: Toast Walnuts and Sage
In a large skillet, melt 2 tablespoons of unsalted butter over medium heat. Once the butter is bubbly, add 1/2 cup of finely chopped walnuts and 1 tablespoon of chopped sage. Toast them for about 5 minutes until fragrant and lightly golden. Transfer this mixture to a bowl and set it aside; the toasted walnuts add a delightful crunch to your Cheesy Pumpkin Pasta Bake.

Step 3: Sauté Vegetables
Using the same skillet, heat 2 tablespoons of extra-virgin olive oil over medium heat. Add 8 oz of sliced cremini mushrooms and 1 finely chopped yellow onion. Sauté the vegetables for about 8 minutes or until they become soft and caramelized, stirring occasionally. The earthy aroma will fill your kitchen, setting the stage for a delicious pasta bake.

Step 4: Build the Flavor Base
Stir in 1/4 cup of tomato paste, 4 minced garlic cloves, and 1/2 teaspoon of crushed red pepper flakes. Cook the mixture for 3-4 minutes, allowing the paste to caramelize slightly. This step enhances the depth of flavor in your pasta bake, giving it a rich base that complements the pumpkin sauce beautifully.

Step 5: Add Greens and Seasoning
Gradually mix in 3 to 4 handfuls of fresh baby spinach, stirring until wilted. Then, season with 1 teaspoon of dried oregano, 1 teaspoon of kosher salt, 1/2 teaspoon of black pepper, and 1/4 teaspoon of ground nutmeg. These spices elevate the taste profile of your Cheesy Pumpkin Pasta Bake, bringing out the warmth of the fall ingredients.

Step 6: Make the Pumpkin Sauce
Deglaze the skillet with 3 cups of vegetable broth, scraping up any browned bits from the bottom. Once the broth is heated through, stir in the entire can (15 oz) of pumpkin purée, 1/2 cup of grated Parmesan cheese, and 1/2 cup of grated Fontina cheese. Cook until the cheeses are melted and the sauce is creamy, creating a smooth mixture ready to coat the pasta.

Step 7: Combine Pasta with Sauce
Gently fold the cooked pasta into the pumpkin sauce, ensuring every piece is well-coated. The creamy pumpkin tomato sauce will cling to the pasta, creating a comforting and indulgent base for your Cheesy Pumpkin Pasta Bake. Mix well to incorporate all the ingredients before transferring to a baking dish.

Step 8: Assemble the Bake
Transfer the pasta mixture into a greased 13×9-inch baking dish, spreading it evenly. Top with the reserved walnut-sage mixture and sprinkle with the remaining 1 cup of grated Fontina cheese, ensuring a cheesy crust. This layer not only contributes flavor but also allows for a beautiful golden topping as it bakes.

Step 9: Bake to Perfection
Cover the baking dish with foil and bake in the preheated oven for 15 minutes. Then, remove the foil and bake for an additional 10 minutes, or until the top is golden and bubbling. The Cheesy Pumpkin Pasta Bake should emerge from the oven with a delightful aroma and a visually tempting layer of melted cheese, inviting you to serve it up warm.

Expert Tips for Cheesy Pumpkin Pasta Bake

  • Pasta Perfection: Ensure your pasta is al dente before mixing; it will continue to cook in the oven, preventing a mushy texture.

  • Nutty Boost: Toast your walnuts until golden for enhanced flavor. Keep a close eye to avoid burning, which can spoil the dish.

  • Pumpkin Power: If using fresh pumpkin, steam or roast until tender before puréeing for the best texture in your Pumpkin Tomato Sauce.

  • Herb Swap: Don’t hesitate to mix it up—thyme or Italian seasoning can replace sage while retaining the comforting essence of the pasta bake.

  • Cheesy Topping Tips: For extra indulgence, add more cheese on top before baking; it creates a crispy, golden crust that’s simply irresistible!

  • Storage Solutions: Leftovers of this Pasta Bake with Pumpkin Tomato Sauce can be kept in the fridge for up to 5 days, making for easy meal prep for busy nights.

Make Ahead Options

This Cheesy Pumpkin Pasta Bake with Mushrooms and Spinach is perfect for meal prep enthusiasts looking to save time on busy weeknights! You can prepare the sauce and mix it with the cooked pasta up to 24 hours in advance. Simply store the combined mixture in an airtight container in the refrigerator; this will allow the flavors to meld beautifully. When you’re ready to serve, transfer to a greased 13×9-inch baking dish, top with remaining cheese and the walnut-sage mixture, and bake straight from the fridge. Just extend the initial covered baking time by about 5 minutes to ensure it heats through evenly. Enjoy a comforting, homemade dinner with minimal effort!
