Step‑by‑Step Instructions for Easy Butternut Squash Pasta Sauce
Step 1: Sauté Vegetables
In a large pot over medium heat, add a splash of olive oil and throw in diced butternut squash, chopped onion, minced garlic, and fresh sage. Season generously with salt and pepper. Stir occasionally and cook for about 10 minutes until the onion is soft and translucent, and the squash begins to soften. The warm, fragrant aroma will fill your kitchen, setting the stage for this delightful butternut squash pasta sauce.
Step 2: Add Broth
Pour in enough vegetable broth to cover the sautéed vegetables—about 2 to 3 cups should do the trick. Increase the heat to high and bring the mixture to a gentle boil. Once boiling, reduce the heat to medium-low and allow it to simmer uncovered for 15-20 minutes. The squash should become very tender and the liquid will reduce by half, intensifying the flavors as it cooks down.
Step 3: Purée Sauce
Once the butternut squash is fork-tender, remove the pot from heat and let it cool slightly. Using either a high-speed blender or immersion blender, purée the mixture until it is completely smooth and creamy. If using a high-speed blender, work in batches if necessary. The creamy butternut squash pasta sauce should have a velvety texture, perfect for coating your favorite pasta.
Step 4: Combine and Serve
For every pound of cooked pasta, mix in approximately 3 cups of the butternut squash sauce, combining thoroughly. If desired, fold in about ⅓ cup of freshly grated Parmesan cheese for added richness. The sauce promises to be luscious and satisfying. Reserve any extra sauce in airtight containers for freezing, avoiding cheese for best results when reheating later.
