Step‑by‑Step Instructions for Butternut Squash Pasta Sauce
Step 1: Preheat and Prepare
Preheat your oven to 450°F (232°C) and line a baking sheet with parchment paper. This will ensure easy cleanup later. While the oven heats, gather your ingredients and make sure your frozen diced butternut squash, fresh chopped tomatoes, and ½ of a sliced yellow onion are ready to go.
Step 2: Arrange the Vegetables
Spread the frozen butternut squash, chopped tomatoes, and sliced onion evenly across the lined baking sheet. The colors should brighten as they come together. This is the foundation for the flavors in your Butternut Squash Pasta Sauce, so arrange them in a single layer to ensure even roasting.
Step 3: Season and Drizzle
Drizzle 2 tablespoons of olive oil over the vegetables, then sprinkle with 1 teaspoon of salt, ¼ teaspoon of black pepper, and ½ teaspoon of dried thyme. Use your hands or a spatula to mix everything until the veggies are well-coated in oil and seasonings, enhancing their natural flavors beautifully.
Step 4: Roast the Veggies
Place the baking sheet in the preheated oven and roast the vegetables at 450°F for 20 minutes. Halfway through, give them a gentle stir to ensure even cooking. You’ll know they’re ready when the butternut squash is tender and slightly caramelized, creating a rich, sweet aroma.
Step 5: Boil the Pasta
While the vegetables are roasting, bring a pot of salted water to a boil and cook 1 pound of pasta according to the package instructions. Stir occasionally to prevent sticking. Aim for al dente texture, as you’ll be tossing it with the sauce later. This usually takes around 8-10 minutes depending on the type of pasta you choose.
Step 6: Reserve Pasta Water
Before draining the cooked pasta, carefully scoop out and reserve ⅓ cup of the pasta water. This starchy water will help you achieve a creamy consistency in your Butternut Squash Pasta Sauce and ensure it clings to the pasta perfectly. Drain the pasta and set it aside.
Step 7: Blend the Sauce
Once the vegetables are tender and caramelized, remove them from the oven and let them cool for a moment. Transfer the roasted veggies to a blender, adding the reserved pasta water. Blend on high until smooth, adjusting the consistency with more pasta water if needed. The sauce should be creamy and vibrant.
Step 8: Combine Sauce and Pasta
Pour the luscious butternut squash sauce over the drained pasta in a large bowl. Toss gently to coat every strand or piece of pasta evenly; this is where the magic happens! You’ll notice the sauce’s lovely color and texture enveloping your pasta, making it a comforting dish.
Step 9: Serve and Enjoy
Serve your Butternut Squash Pasta Sauce immediately, topped with a generous sprinkle of parmesan cheese or a plant-based alternative if desired. The warmth of the dish, combined with the creamy sauce, creates a delightful experience. Gather your loved ones around the table and enjoy this comforting meal together.
