Step‑by‑Step Instructions for Pasta Bake with Pumpkin Tomato Sauce

Step 1: Preheat the Oven
Begin by preheating your oven to 375ºF (190ºC). This is crucial for achieving that bubbly, golden crust on your Pasta Bake with Pumpkin Tomato Sauce. While the oven warms up, gather your ingredients and prepare your baking dish by greasing it lightly to prevent sticking.

Step 2: Cook the Pasta
Bring a large pot of salted water to a rolling boil. Add your dry pasta and cook it for about 2 minutes less than the package instructions for al dente texture. Drain the pasta and set it aside. This method ensures your pasta remains firm when baked, resulting in a delightful texture.

Step 3: Toast the Nuts and Sage
In a large sauté pan, melt the unsalted butter over medium heat. Add the finely chopped walnuts and fresh sage, toasting them together for about 5 minutes until fragrant and slightly golden. Once done, transfer the mixture to a bowl for later use, allowing the nuts to cool while you continue preparing the bake.

Step 4: Sauté the Vegetables
In the same sauté pan, add the extra-virgin olive oil and heat it over medium-high heat. Once hot, toss in the sliced cremini mushrooms and finely chopped onion. Sauté everything together for about 8 minutes until the vegetables are tender and golden, filling your kitchen with delightful aromas.

Step 5: Add Tomato Paste and Spices
Next, stir in the tomato paste, minced garlic, and crushed red pepper flakes into the sautéed vegetables. Cook this mixture for about 3 to 4 minutes, allowing the tomato paste to caramelize slightly. This step builds a deep, rich flavor for your Pasta Bake with Pumpkin Tomato Sauce.

Step 6: Incorporate the Spinach and Seasonings
Gradually add the fresh baby spinach, stirring until it wilts down completely. Then, sprinkle in the dried oregano, kosher salt, black pepper, and ground nutmeg, mixing well to combine all those fragrant notes. This blend of spices enhances the overall profile of your comforting pasta bake.

Step 7: Make the Pumpkin Sauce
Deglaze the pan by pouring in the vegetable broth, scraping any browned bits from the bottom. Add the pumpkin purée, grated Parmesan cheese, and 1/2 cup of grated fontina to the mixture. Stir continuously until everything is melted and smooth, creating a creamy sauce that’s bursting with fall flavors.

Step 8: Mix Pasta with the Sauce
In a large mixing bowl, combine the cooked pasta with the luscious pumpkin sauce. Toss everything together until the pasta is thoroughly coated with the creamy mixture, ensuring that every bite of your Pasta Bake with Pumpkin Tomato Sauce is filled with flavor and richness.

Step 9: Assemble the Pasta Bake
Transfer the pasta mixture into your greased 13×9-inch baking dish, spreading it evenly. Top it with the remaining grated fontina and the walnut-sage mixture. This topping adds a delightful crunch and extra flavor, preparing it for the oven.

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 bake for an additional 10 minutes or until the top is golden and bubbly. Keep an eye on it to ensure the perfect finish—golden brown is what you want!

Step 11: Cool and Serve
Once baked, take the dish out of the oven and allow it to cool for a few minutes. This pause lets the layers settle, making it easier to serve. Your cozy Pasta Bake with Pumpkin Tomato Sauce is now ready to be enjoyed!
