Pasta Bake with Pumpkin Tomato Sauce Ingredients

For the Pasta
• Pasta – 1 lb. dry pasta like mezzi rigatoni or shells serves as the hearty base for this dish; cook until just under al dente for perfect texture.

For the Sauce
• Butter – 2 Tbsp. adds richness to the walnut-sage topping; can be swapped for olive oil for a dairy-free version.
• Olive Oil – 2 Tbsp. used for sautéing vegetables; any neutral oil can work in its place.
• Mushrooms – 8 oz. sliced cremini mushrooms offer umami and volume; white button mushrooms are a good substitute.
• Onion – 1 finely chopped yellow onion provides aromatic depth; shallots can be used for a milder flavor.
• Garlic – 4 minced cloves are essential for a robustly flavorful sauce; garlic powder can step in if needed (1 tsp. is equivalent).
• Tomato Paste – 1/4 cup deepens the sauce’s flavor dramatically; use tomato sauce as an alternative but adjust spices accordingly.
• Crushed Red Pepper Flakes – 1/2 tsp. to add a hint of heat; feel free to omit for a milder dish.
• Fresh Spinach – 3 to 4 handfuls introduce nutrition and color; kale can serve as a tasty substitute.
• Dried Oregano – 1 tsp. for added seasoning; Italian seasoning works well as an alternative.
• Kosher Salt – 1 tsp. enhances overall flavor; adjust according to taste or dietary needs.
• Black Pepper – 1/2 tsp. brings a touch of spice; freshly cracked pepper is recommended for best flavor.
• Ground Nutmeg – 1/4 tsp. adds warmth and depth; cinnamon can be an interesting substitute!
• Vegetable Broth – 3 cups serve as the sauce’s liquid base; chicken broth can be used if vegetarian isn’t a priority.
• Pumpkin Puree – 1 (15-oz.) can is the star of this dish; fresh pumpkin can be pureed if you prefer.

For the Cheese
• Parmesan Cheese – 1/2 cup grated adds creaminess and flavor; nutritional yeast is a fantastic dairy-free alternative.
• Fontina Cheese – 1 1/2 cups grated (divided) provides gooey texture and rich flavor; alternatives like Havarti or Gruyère are also great.

For the Topping
• Walnuts – 1/2 cup finely chopped for crunch and flavor; pecans can work in a pinch.
• Sage – 2 Tbsp. finely chopped fresh leaves lend aromatic flavor; dried sage can replace it, although fresh is best.

Let’s create a memorable family meal that embodies all the warmth and joy of autumn!

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

Step 1: Preheat and Prepare Pasta
Begin by preheating your oven to 375°F (190°C). While that heats up, bring a large pot of salted water to a rolling boil. Once boiling, add your 1 lb. of dry pasta and cook until it’s just shy of al dente, about 2 minutes less than package instructions. Drain the pasta and set it aside to cool slightly.

Step 2: Toast Walnuts and Sage
In a large skillet over medium heat, melt 2 tablespoons of butter. Once melted, add 1/2 cup of finely chopped walnuts and 2 tablespoons of freshly chopped sage. Toast this mixture for about 5 minutes, stirring frequently until the walnuts are golden and fragrant. Transfer to a bowl and set aside, allowing the flavors to meld.

Step 3: Sauté Vegetables
In the same skillet, add 2 tablespoons of olive oil and heat over medium heat. Then, add 8 oz. of sliced cremini mushrooms and 1 finely chopped yellow onion. Cook until the mushrooms are softened and the onion is translucent, around 7-8 minutes. This step builds the savory base for our Cheesy Pumpkin Pasta Bake.

Step 4: Add Aromatics
Next, stir in 1/4 cup of tomato paste, 4 minced garlic cloves, and 1/2 teaspoon of crushed red pepper flakes into the skillet. Cook this mixture for an additional 2-3 minutes, stirring continuously until the tomato paste turns a deep brick red, enhancing the flavors of the sauce as it develops.

Step 5: Incorporate Spinach and Seasonings
Add 3 to 4 handfuls of fresh spinach to the skillet, stirring until it wilts, which should take about 2 minutes. Then, sprinkle in 1 teaspoon of dried oregano, 1 teaspoon of kosher salt, 1/2 teaspoon of black pepper, and 1/4 teaspoon of ground nutmeg. This aromatic blend will elevate the depth of flavor in your pumpkin sauce.

Step 6: Create the Sauce
Pour in 3 cups of vegetable broth to deglaze the pan, scraping any browned bits. Stir in 1 can (15 oz.) of pumpkin puree along with 1/2 cup of grated Parmesan and 1/2 cup of grated fontina cheese. Mix until the cheese has melted, creating a creamy sauce that will perfectly coat the pasta.

Step 7: Combine Pasta with Sauce
Add the drained pasta to the pumpkin sauce mixture, tossing gently to ensure every piece is well-coated with the rich mixture. This step is crucial for achieving a harmonious blend of textures and flavors in your Cheesy Pumpkin Pasta Bake.

Step 8: Assemble in Baking Dish
Transfer the pasta and sauce mixture into a greased 13×9-inch baking dish, spreading it out evenly. Top with the remaining 1 cup of grated fontina cheese and sprinkle the toasted walnut-sage mixture generously over the top to create a deliciously crunchy layer.

Step 9: Bake the Dish
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 10-15 minutes, or until the top is golden and bubbling. This final bake melds the flavors beautifully, ensuring every bite is a comforting delight.

Cheesy Pumpkin Pasta Bake with Mushrooms and Spinach Recipe FAQs

What kind of pasta should I use for this dish?
Absolutely! You can use any dry pasta for this Cheesy Pumpkin Pasta Bake, but I recommend tubular shapes like mezzi rigatoni or shells. These types hold the creamy pumpkin tomato sauce beautifully. Be sure to cook the pasta until just shy of al dente, usually 2 minutes less than package instructions, so it maintains a perfect texture after baking.

How should I store leftovers?
Leftovers can be stored in an airtight container in the refrigerator for up to 5 days. It’s best to allow the pasta bake to cool completely before sealing it to maximize freshness. I often make this dish ahead of time, and the yummy flavors just get better!

Can I freeze the Cheesy Pumpkin Pasta Bake?
Certainly! You can freeze this delicious dish for up to 3 months. To do so, wrap the cooled pasta bake tightly in plastic wrap, followed by aluminum foil to prevent freezer burn. When you’re ready to enjoy it again, thaw it overnight in the refrigerator before reheating in the oven.

What if my pasta becomes mushy during baking?
No worries! If your pasta does turn mushy, it may be because it was cooked too long before baking. To avoid this, always ensure that you cook your pasta until just under al dente, which keeps it firm while the dish bakes. Using the recommended pasta shapes also helps to hold up better.

Is this dish suitable for those with allergies?
Definitely! This Cheesy Pumpkin Pasta Bake is vegetarian-friendly and can be made gluten-free by using gluten-free pasta. If you or your guests have nut allergies, you can skip the walnuts entirely or substitute them with breadcrumbs for a crunchy topping. Always double-check the labels of your ingredients to ensure they meet your dietary needs.

How do I add extra flavor to the sauce?
For an extra flavor boost, consider adding more fresh herbs to the sauce, like thyme or basil, or even a splash of balsamic vinegar for depth. I love mixing in a bit more cheese into the sauce—like mozzarella or goat cheese—before coating the pasta. This makes for a creamier, richer experience in each bite!
