Ingredients:

• 16 oz bag of frozen diced butternut squash
• 1.5 cups fresh chopped tomatoes
• 1/2 yellow onion, finely chopped
• 2 tbsp olive oil
• 1 tsp salt
• 1/4 tsp black pepper
• 1/2 tsp dried thyme
• 1 lb pasta (your favorite shape!)
• 1/3 cup pasta water reserved from cooked pasta

Cooking Instructions

Let’s break down how to make this delicious butternut squash pasta sauce. It’s a straightforward process that yields impressive results.

Phase 1: Sautéing the Aromatics

1. Begin by heating the 2 tablespoons of olive oil in a large pot or Dutch oven over medium heat. Once the oil is shimmering, add the finely chopped half yellow onion. We want to sauté the onion until it becomes translucent and begins to soften, which usually takes about 5-7 minutes. This process of gently cooking the onion releases its natural sweetness and forms the flavor base for our sauce. Don’t rush this step; allowing the onion to soften properly will prevent any harsh oniony bite in the final sauce. Stir occasionally to ensure even cooking.

Phase 2: Building the Sauce Base

2. Once the onion is softened and fragrant, add the 1.5 cups of fresh chopped tomatoes to the pot. Stir them in with the onions and let them cook for about 5 minutes, or until they start to break down and release their juices. The tomatoes will add a touch of acidity and freshness to the sauce, balancing the sweetness of the squash. Next, sprinkle in the 1 teaspoon of salt, 1/4 teaspoon of black pepper, and 1/2 teaspoon of dried thyme. Stir everything together, allowing the herbs and seasonings to meld with the onions and tomatoes for another minute. The aroma at this stage is already quite inviting!

Phase 3: Simmering the Squash

3. Now it’s time to introduce the star of our sauce: the 16 oz bag of frozen diced butternut squash. Add the frozen squash directly into the pot with the sautéed onions and tomatoes. Stir everything to combine. We’re going to add just enough liquid to help the squash cook down and become tender. Pour in about 1 cup of water or vegetable broth (you can adjust this slightly if needed). Bring the mixture to a simmer, then reduce the heat to low, cover the pot, and let it cook for about 15-20 minutes, or until the butternut squash is fork-tender and easily pierced. Stir occasionally to prevent sticking. The frozen squash will cook down beautifully, softening and releasing its creamy texture.

Phase 4: Achieving Creaminess and Blending

4. Once the butternut squash is tender, it’s time to create that signature smooth and creamy sauce. You have a couple of options here depending on your preferred texture. For a rustic, slightly chunky sauce, you can use an immersion blender directly in the pot and blend until you reach your desired consistency. Be careful of splashing hot liquid! Alternatively, you can carefully transfer the contents of the pot to a regular blender in batches (do not fill the blender more than halfway and vent the lid slightly by removing the small center cap and covering it with a towel to allow steam to escape). Blend until completely smooth and creamy. If you don’t have a blender, you can also mash the squash really well with the back of a spoon or a potato masher, though it won’t be as uniformly smooth.

5. After blending, return the smooth sauce to the pot if you used a regular blender. Now, we’ll add the final touches to bring it all together. Stir in the 1/3 cup of reserved pasta water. This starchy water is magic! It helps to emulsify the sauce, making it even more velvety and helping it cling beautifully to your pasta. Cook the sauce for another 2-3 minutes over low heat, stirring constantly, until it’s heated through and has a luxurious consistency. Taste and adjust seasonings if needed, adding a pinch more salt or pepper if you think it requires it.

Phase 5: Combining with Pasta

6. While your sauce is simmering, cook your 1 lb of pasta according to package directions in a large pot of salted boiling water. Before draining the pasta, make sure to reserve about 1/3 cup of the starchy cooking water – this is crucial for achieving the perfect sauce consistency as mentioned in step 5. Drain the pasta well. Add the drained pasta directly into the pot with the butternut squash sauce. Toss gently to coat every strand of pasta evenly. If the sauce seems a little too thick for your liking, you can add a tablespoon or two more of the reserved pasta water until you achieve your desired texture. Serve immediately, perhaps with a sprinkle of Parmesan cheese or fresh parsley if you like. Enjoy this comforting and wholesome dish!

For serving, this sauce is fantastic tossed with your favorite pasta shape – think rigatoni, penne, or even a delicate fettuccine. For added flair, consider garnishing with toasted pumpkin seeds for a delightful crunch, a sprinkle of fresh sage or rosemary, and a drizzle of good quality olive oil. If you’re feeling adventurous with variations, try adding a pinch of nutmeg for warmth, a touch of smoked paprika for depth, or even some roasted garlic for an extra layer of savory goodness. Don’t be afraid to experiment and make it your own!
