Step‑by‑Step Instructions for Cheesy Pumpkin Pasta Bake with Walnut-Sage Topping
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures the Cheesy Pumpkin Pasta Bake cooks evenly. While the oven warms up, gather your ingredients and prepare your baking dish by lightly greasing it. This step is crucial for achieving that golden, bubbly topping later on.
Step 2: Cook the Pasta
In a large pot, bring salted water to a rolling boil. Add the dry pasta of your choice and cook until just 2 minutes shy of al dente—this usually takes about 7-9 minutes. Drain the pasta and set it aside in a bowl to prevent sticking as you prepare the sauce.
Step 3: Prepare the Walnut-Sage Topping
In a large skillet over medium heat, melt 2 tablespoons of butter. Add the chopped walnuts and 1 tablespoon of fresh sage, cooking for about 3-4 minutes until the walnuts are golden and fragrant. Stir occasionally to prevent burning, then transfer this mixture to a bowl and set aside.
Step 4: Sauté the Vegetables
Using the same skillet, heat 2 tablespoons of extra-virgin olive oil over medium heat. Add diced cremini mushrooms and chopped yellow onion, sautéing for about 8 minutes until softened. This aromatic blend forms a flavorful base for your Pasta Bake, so keep stirring until the onions are translucent and the mushrooms are browned.
Step 5: Incorporate the Tomato Mixture
Next, stir in the tomato paste, minced garlic, and crushed red pepper flakes. Cook this mixture for 3-4 minutes, stirring frequently, until the tomato paste caramelizes slightly. You'll know it’s ready when it deepens in color and embodies a rich, tangy aroma, enhancing the overall flavor of the sauce.
Step 6: Add the Greens and Seasoning
Gradually add the baby spinach to the skillet, stirring continuously until wilted—this takes about 2-3 minutes. Season the sautéed mixture with dried oregano, kosher salt, black pepper, and a dash of ground nutmeg, which complements the pumpkin beautifully. Mix well to ensure even seasoning throughout.
Step 7: Create the Pumpkin Tomato Sauce
Pour in the vegetable broth, using a wooden spoon to deglaze the pan—scrape up any flavor bits stuck to the bottom. Then, stir in the pumpkin purée and both cheeses (Parmesan and Fontina) until everything is melted and smooth, creating a luscious sauce. This will be the heart of your Cheesy Pumpkin Pasta Bake.
Step 8: Combine Pasta and Sauce
Add the drained pasta to the skillet with the creamy pumpkin tomato sauce. Stir everything together until the pasta is well-coated, ensuring each piece is enveloped in that delicious sauce. This step is crucial for a comforting and cohesive dish—don’t rush it!
Step 9: Assemble the Dish
Transfer the pasta mixture into your greased baking dish, spreading it evenly. Top it generously with the remaining grated Fontina cheese and the walnut-sage mixture you prepared earlier. This mixture will create that irresistible, crunchy topping once baked.
Step 10: Bake and Finish
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. You'll know it's done when the top is golden, bubbly, and fragrant, making your kitchen smell like autumn goodness!
Step 11: Let It Rest
After removing the Cheesy Pumpkin Pasta Bake from the oven, let it rest for about 5 minutes before serving. This helps the layers set a bit, making each serving even more satisfying. Pair it with a fresh side salad for a complete meal bursting with fall flavors!
How to Store and Freeze Cheesy Pumpkin Pasta Bake
Fridge: Leftovers can be stored in an airtight container for up to 5 days. Be sure to cool the pasta bake before sealing it to maintain freshness.
Freezer: This comforting dish freezes wonderfully for up to 3 months. For best results, let it cool completely, then wrap tightly in plastic wrap and aluminum foil.
Thawing: When ready to enjoy, thaw the frozen Pasta Bake with Pumpkin Tomato Sauce overnight in the refrigerator before reheating.

Cheesy Pumpkin Pasta Bake with Walnut-Sage Topping Recipe FAQs
How do I choose the right pumpkin for this recipe?
Absolutely! When selecting pumpkin, look for small, firm ones with a smooth, unblemished skin. Sugar pumpkins are a great choice for their sweetness and smooth texture. Avoid pumpkins that show dark spots or feel overly soft—these are signs of overripeness.
How should I store leftovers of this Pasta Bake with Pumpkin Tomato Sauce?
Leftovers can be stored in an airtight container and refrigerated for up to 5 days. Make sure to let the dish cool before sealing it to keep it fresh and flavorful. Reheating is a breeze; just pop it back in the oven at 350°F until warmed through!

Very! To freeze, let the Pasta Bake cool completely and then wrap it tightly in plastic wrap and aluminum foil to prevent freezer burn. It can be frozen for up to 3 months. When you're ready to enjoy it, simply thaw it overnight in the refrigerator and bake as instructed.
What should I do if the pasta is too dry after baking?
If you find your pasta bake has dried out, don't worry! You can stir in a splash of vegetable broth or cream when reheating to add moisture back into the dish. Next time, ensure to coat the pasta thoroughly with sauce before baking, as this will help keep it nice and creamy.
Is this dish suitable for people with nut allergies?
I recommend replacing the walnuts in the topping with toasted breadcrumbs or sunflower seeds for a nut-free option. This way, you can maintain that crunch without the allergens. Always check ingredient labels to avoid cross-contamination!
Can I adjust the cheese for dietary preferences?
Absolutely! You can substitute the grated Parmesan and Fontina with nutritional yeast for a vegan option, or use dairy-free cheese alternatives that melt well. Just make sure to choose a cheese that complements the flavor profile of the dish for the best results.
