Step‑by‑Step Instructions for Cheesy Pumpkin Pasta Bake with Mushrooms and Spinach
Step 1: Preheat the Oven
Begin by preheating your oven to 375ºF (190ºC), ensuring it’s hot enough to create a lovely golden crust on your Cheesy Pumpkin Pasta Bake. While the oven warms, gather your ingredients and equipment like a large pot for cooking pasta and a baking dish ready for assembly.
Step 2: Cook the Pasta
In a large pot, bring salted water to a boil and cook 1 lb. of dry pasta until it’s just 2 minutes shy of al dente, about 6-7 minutes. Once cooked, drain the pasta and set it aside, allowing it to dry slightly as you prepare the flavorful sauce that will coat every noodle of this comforting dish.
Step 3: Prepare the Walnut-Sage Topping
In a large sauté pan, melt 2 tablespoons of unsalted butter over medium heat. Add 1/2 cup of finely chopped walnuts and 1 tablespoon plus 2 teaspoons of chopped fresh sage leaves, cooking for about 5 minutes, or until the walnuts are toasted and fragrant. Transfer the mixture to a bowl and set aside to create a crunchy topping.
Step 4: Sauté the Vegetables
Using the same sauté pan, add 2 tablespoons of extra-virgin olive oil and heat over medium heat. Stir in 8 oz. of sliced cremini mushrooms and 1 finely chopped yellow onion, cooking for approximately 8 minutes until both are softened and the onions are translucent, enhancing the savory base of the pasta bake.
Step 5: Build the Sauce
Once the vegetables are tender, add 1/4 cup of tomato paste, 4 minced garlic cloves, and 1/2 teaspoon of crushed red pepper flakes to the pan. Stir continuously for about 3-4 minutes until the tomato paste caramelizes, developing a deep, rich flavor that will blend deliciously into your pumpkin sauce.
Step 6: Add the Greens and Seasoning
Next, gradually fold in 3 to 4 handfuls of fresh baby spinach into the pan, stirring until the leaves are wilted, which should take just a couple of minutes. Season the 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 for a fragrant touch to your Cheesy Pumpkin Pasta Bake.
Step 7: Create the Pumpkin Tomato Sauce
Now, it’s time to deglaze the pan: pour in 3 cups of vegetable broth, scraping up any brown bits from the bottom. Stir in 1 (15-oz.) can of pumpkin purée, 1/2 cup of grated Parmesan cheese, and 1/2 cup of grated fontina cheese, mixing until smooth. The sauce should be creamy and vibrant, ready to embrace the pasta.
Step 8: Combine the Pasta and Sauce
In a large mixing bowl, combine the cooked pasta with the pumpkin tomato sauce, ensuring each noodle is well-coated in the rich, creamy goodness. This comforting mixture of your Pasta Bake with Pumpkin Tomato Sauce will be the heart of your dish, full of flavor and nourishment.
Step 9: Assemble in the Baking Dish
Transfer the pasta mixture into a greased 13×9-inch baking dish, spreading it evenly. Top with the remaining 1 cup of grated fontina cheese and the walnut-sage mixture that you prepared earlier, creating a delightful contrast of buttery crunch atop the cheesy pasta.
Step 10: Bake to Perfection
Cover the baking dish with foil and place it in the preheated oven to bake for 15 minutes. Then, uncover the dish and bake for an additional 10 minutes until the cheese is melted and golden brown, creating that irresistible bubbly crust that signals deliciousness in every bite of your Cheesy Pumpkin Pasta Bake.
