Ingredients:
- 16 oz frozen diced butternut squash
- 1.5 cups fresh chopped tomatoes
- 1/2 yellow onion, finely chopped
- 2 tbsp olive oil
- 1 tsp salt, plus more for pasta water
- 1/4 tsp black pepper
- 1/2 tsp dried thyme
- 1 lb pasta of your choice (such as fettuccine, penne, or rotini)
- 1/3 cup reserved pasta water
Preparing the Butternut Squash Base
Sautéing the Aromatics
First, let’s get our aromatics going. Heat the 2 tablespoons of olive oil in a large skillet or Dutch oven over medium heat. Once the oil is shimmering, add the finely chopped yellow onion. We want to cook the onion until it becomes translucent and starts to soften, which usually takes about 5-7 minutes. Stir it occasionally to prevent any sticking. This gentle sautéing will release the natural sweetness of the onion and form a delicious base for our sauce.
Adding the Butternut Squash and Tomatoes
Once the onion is softened, it’s time to add the star ingredients. Add the 16 ounces of frozen diced butternut squash directly to the skillet. You don’t need to thaw it beforehand; it will cook down beautifully in the sauce. Stir everything together, coating the squash in the olive oil and onion mixture. Now, add the 1.5 cups of fresh chopped tomatoes. The tomatoes will release their juices as they cook, helping to deglaze the pan and add a lovely acidity to the sauce.
Simmering and Softening
Reduce the heat to medium-low, cover the skillet, and let the butternut squash and tomatoes simmer gently. We want to cook this mixture until the butternut squash is fork-tender. This process typically takes about 15-20 minutes. Stir occasionally to ensure even cooking and to prevent the squash from sticking to the bottom of the pan. If the mixture seems a bit dry, you can add a splash of water or vegetable broth, but usually, the moisture from the tomatoes and squash is enough.
Creating the Creamy Sauce
Blending the Sauce
Once the butternut squash is completely tender, it’s time to transform this mixture into a smooth and creamy sauce. Carefully transfer the contents of the skillet to a blender. If you don’t have a high-powered blender, you might need to do this in batches. Add the 1 teaspoon of salt, 1/4 teaspoon of black pepper, and 1/2 teaspoon of dried thyme to the blender. Secure the lid tightly, and begin extract blending on a low speed, gradually increasing to high. Blend until the sauce is incredibly smooth and velvety. Be cautious when blending hot liquids, as steam can build up and cause the lid to lift. You can remove the small center cap from the blender lid and cover it with a folded kitchen towel to allow steam to escape safely.
Adjusting Consistency and Flavor
Return the blended sauce to the skillet over low heat. Now, we’ll add the reserved pasta water. Pour in the 1/3 cup of reserved pasta water. This starchy water is magic! It helps to emulsify the sauce, making it even smoother and more luxurious, and it also helps the sauce cling beautifully to the pasta. Stir the sauce well. Taste the sauce and adjust the seasoning if needed. You might want to add a little more salt or pepper depending on your preference. If the sauce is too thick, you can add another tablespoon or two of pasta water until you reach your desired consistency. If it’s too thin, let it simmer gently uncovered for a few extra minutes to reduce.
Cooking the Pasta and Combining
Boiling the Pasta
While the sauce is gently warming, bring a large pot of generously salted water to a rolling boil. Add your 1 pound of pasta and cook according to the package directions until it’s al dente. This means the pasta should be tender but still have a slight bite. Before draining the pasta, be sure to reserve about 1/3 cup of the starchy cooking water. This is what we’ve already incorporated into the sauce, but it’s always good to have a little extra on hand in case you need to loosen the sauce further.
Tossing with Sauce
Drain the cooked pasta well. Add the drained pasta directly to the skillet with the warm butternut squash pasta sauce. Toss everything together thoroughly, ensuring that every strand or piece of pasta is generously coated in the rich, creamy sauce. Let the pasta and sauce sit together for about 1-2 minutes over low heat, allowing the flavors to meld and the sauce to adhere to the pasta. This brief resting period makes a significant difference in the final dish.
Serving Suggestions
Serve this delicious Butternut Squash Pasta Sauce immediately. It’s wonderful on its own, but you can elevate it further with a sprinkle of freshly grated Parmesan cheese, a drizzle of egin extracta virgin olive oil, or some toasted pine nuts for added texture and flavor. A side of crusty bread is perfect for soaking up any leftover sauce.
