Ingredient Notes

- Pumpkin purée: This is the star of the show! It adds that lovely creamy texture. Go for canned purée for ease, but fresh cooked pumpkin works too if you’re up for it.
- Dry pasta: Grab any shape you prefer! Just steer clear of long pasta like spaghetti. Shells or penne hold sauce beautifully, making every bite satisfying.
- Tomato paste: It packs a punch of flavor! Don’t skip on sautéing it until it gets that brick red color. Makes such a difference in taste.
- Cremini mushrooms: These add an earthy depth that really complements the pumpkin. Fresh is key, and give them a good rinse before slicing to clean them up.
- Grated fontina cheese: This cheese melts like a dream and gives a nutty richness to the dish. If you can’t find it, try mozzarella or gruyere instead for a similar meltiness.

Recipe Tips
- If pasta becomes mushy, cooking it just 2 minutes less than al dente will keep it firm during baking.
- When using tomato paste, sauté it until it achieves a brick red color to deepen its flavor.
- For reheating leftovers, a splash of broth helps maintain moisture and prevents the dish from drying out.
- If walnut topping tends to burn, sprinkling it on halfway through baking provides a nice texture without char.
- When sauce thickens too much after cooking, adding extra broth can help loosen it up before you bake.
Serving Suggestions
- Serve this pumpkin pasta bake with a side salad for freshness. Roasted vegetables and meatballs add extra nutrition and heartiness to the meal.
- Consider using this dish as a filling for stuffed peppers or layered in lasagna. It also pairs well with baked chicken or fish dishes.
- A light garlic sauce or a sprinkle of fresh herbs can enhance the flavors. Adding a sprinkle of parmesan cheese before serving brings added depth to the dish.
Storage Guidelines
- To keep your pumpkin pasta bake fresh, follow these storage tips:
- Refrigeration: Store leftovers in an airtight container in the refrigerator for up to 5 days to maintain freshness.
- Freezing: Wrap the pumpkin pasta bake tightly in plastic wrap or aluminum foil. Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
- Reheating: Once thawed, reheat in the oven or on the stove. Add a splash of broth to keep it moist.
Recipe Variations
- You can use butternut squash purée instead of pumpkin for a different flavor that still offers creaminess and sweetness.
- Add 1 teaspoon garlic powder and 1/2 teaspoon paprika for an extra layer of flavor that complements the cheese and pumpkin.
- Either swap in roasted red peppers or add spinach for a touch of color and a slight twist on the dish’s flavor profile.
- For a larger batch, double the amounts to use 30-oz. can pumpkin purée, 2 lb. dry pasta, and 3 cups grated fontina cheese.

Pasta Bake with Pumpkin Tomato Sauce

Equipment
- Large Baking Dish
- Stockpot or Dutch oven
- Large sauté pan
Ingredients
- 1 lb. dry pasta of choice such as mezzi rigatoni, shells, ziti or other tubular pasta, fusilli, or farfalle
- 2 Tbsp. butter
- ½ cup finely chopped walnuts
- 2 Tbsp. finely chopped fresh sage leaves
- 2 Tbsp. extra-virgin olive oil
- 8 oz. cremini (baby bella) mushrooms sliced
- 1 yellow onion finely chopped
- ¼ cup tomato paste
- 4 garlic cloves minced
- ½ tsp. crushed red pepper flakes
- fresh baby spinach 3 to 4 handfuls
- 1 tsp. dried oregano
- 1 tsp. kosher salt
- ½ tsp. black pepper
- ¼ tsp. ground nutmeg
- 3 cups vegetable broth
- 1 (15-oz.) pumpkin purée
- ½ cup grated Parmesan cheese
- 1 ½ cups grated fontina cheese divided
Instructions
- Start by boiling water to cook your pasta until it is just barely firm. You will want it to be a couple of minutes short of al dente. This helps it hold its shape in the bake. Overcooking it now could lead to mushiness later, so keep an eye on it.
- Heat the butter and olive oil in a pan, letting them sizzle and fill the air with a buttery aroma. Once melted, toss in the onions and garlic until they are soft and translucent. This step adds a rich base flavor, so do not rush it.
- Stir in the sliced mushrooms and walnuts, letting them sauté until the mushrooms are tender and start to brown. You will want to see the mushrooms releasing their moisture. If they are too dry, they will not blend well in the bake.
- Add in the tomato paste and let it cook until it turns a deep, brick red. You will notice a more intense flavor developing. It might seem trivial, but skipping this can lead to a bland sauce.
- Mix in the baby spinach, oregano, salt, black pepper, nutmeg, and crushed red pepper flakes. As the spinach wilts, it will shrink down significantly, so do not worry if it seems like too much at first.
- Pour in the vegetable broth and pumpkin purée, stirring everything together until it is a smooth mixture. It should smell comforting and warm. This is where the creamy sauce comes to life, so keep your heat steady.
- Stir the cooked pasta into the sauce, letting it soak up all those delicious flavors. It should all feel well-mixed and look like a colorful blend. Just ensure every piece of pasta is coated evenly; otherwise, some bites may taste bland.
- Transfer half of the pasta mixture to a baking dish, then sprinkle with half of the fontina cheese. Pour the rest of the pasta on top and finish with the remaining fontina and Parmesan cheese. This melty cheesy layer is key, so spread it evenly.
- Pop the dish in the oven and let it bake until the cheese is bubbly and golden brown. You will know it is ready when you see that cheesy top browning slightly. Sometimes folks take it out too early—do not rush this step!
- Once it is out, let the pasta bake cool for a bit before serving. The sauce will thicken slightly as it cools, making it easier to serve. Do not skip this step, as it will help everything hold together nicely.
