How to Make Butternut Squash Pasta Sauce Recipe

Step 1: Prepare and Roast the Vegetables

Start by preheating your oven to 450°F and lining a baking sheet with parchment paper. Spread out the frozen butternut squash, fresh chopped tomatoes, and sliced yellow onion evenly on the sheet. Drizzle the olive oil over the vegetables and sprinkle the salt, black pepper, and dried thyme on top. Toss everything gently to coat well. Roast the veggies in the hot oven for 20 minutes until tender and a little caramelized around the edges, which enhances their natural sweetness.

Step 2: Cook the Pasta

While the vegetables are roasting, bring a large pot of salted water to a boil and cook your chosen pasta according to the package instructions. The goal is perfectly al dente pasta that will hold the sauce beautifully. Just before draining the pasta, be sure to scoop out 1/3 cup of the starchy pasta water – this will be a secret weapon for smoothing out the sauce.

Step 3: Blend the Sauce

Once the roasted vegetables are straight out of the oven, toss them into a blender along with the reserved pasta water. Blend until you get a smooth, luscious sauce that envelops the palate with creamy richness and a pop of herbaceous flavor from the thyme. This vibrant sauce is the heart of your dish, perfect to pour over the warm pasta.

Step 4: Combine and Toss

Pour the freshly blended butternut squash pasta sauce over the hot pasta in your pot or pan. Toss gently but thoroughly to ensure every noodle is lovingly coated in that dreamy sauce. The pasta water you reserved helps the sauce stick perfectly and creates a silky, unified dish ready to delight your taste buds.
