Step‑by‑Step Instructions for Creamy Butternut Squash Pasta Sauce
Step 1: Preheat the Oven
Begin by preheating your oven to 450°F (232°C). While the oven warms, line a baking sheet with parchment paper to prevent sticking and ensure easy cleanup. This setup is vital for roasting the vegetables to enhance the flavors of your creamy butternut squash pasta sauce.
Step 2: Prepare the Vegetables
Next, arrange the frozen butternut squash, chopped tomatoes, and sliced onion evenly on the prepared baking sheet. This combination will create a delicious medley, so spread them out to allow for even roasting.
Step 3: Season and Coat
Drizzle the vegetables with olive oil, then sprinkle them with salt, black pepper, and dried thyme. Toss everything well to ensure the squash and tomatoes are evenly coated with the seasonings. This step is crucial for unlocking the deep flavors in your butternut squash pasta sauce.
Step 4: Roast the Vegetables
Place the baking sheet in the preheated oven and roast the vegetables for 20 minutes. Keep an eye out for the vegetables to become tender and slightly caramelized, which will give the sauce its rich, complex flavor.
Step 5: Cook the Pasta
While the vegetables are roasting, cook your pasta according to the package instructions until al dente. Don’t forget to reserve a cup of the pasta water before draining; this will be essential for achieving the perfect creamy consistency for your butternut squash pasta sauce.
Step 6: Blend the Sauce
Once the vegetables are roasted, transfer them to a blender. Add about 1/3 cup of the reserved pasta water to the blender and blend until you achieve a smooth, creamy texture. This blended mix will become the sumptuous sauce that coats your pasta beautifully.
Step 7: Combine and Serve
In a large mixing bowl, toss the hot pasta with the blended butternut squash sauce until every piece is well coated. The sauce should cling lovingly to the pasta, creating a comforting dish. Serve immediately, offering optional garnishes like vegan parmesan for added flavor.
Make Ahead Options
These Butternut Squash Pasta Sauce preparations are ideal for meal prep enthusiasts! You can roast the butternut squash, tomatoes, and onions up to 24 hours in advance and store them in the refrigerator. Simply prepare them on a baking sheet, drizzle with olive oil, and season before roasting. Once roasted, blend the mixture with reserved pasta water when you’re ready to cook. To maintain the sauce’s rich, creamy texture, store the finished sauce in an airtight container for up to 3 days in the fridge or freeze it for up to 3 months. When it’s time to serve, just reheat the sauce and toss it with freshly cooked pasta for a satisfying meal!
