Ingredients
  

  • 1 medium butternut squash peeled and cubed (about 4 cups)
  • 1 tablespoon olive oil
  • 1 small onion diced
  • 3 garlic cloves minced
  • 1 teaspoon salt divided (adjust to taste)
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon ground nutmeg optional, but recommended for a warm flavor
  • 1/2 teaspoon dried sage or 2 teaspoons fresh sage, chopped
  • 1 cup vegetable broth or chicken broth for a richer flavor
  • 1/2 cup heavy cream or coconut milk for a dairy-free option
  • 1/4 cup grated Parmesan cheese optional, for extra richness
  • 1 tablespoon lemon juice optional, for a hint of brightness

Instructions
 

  • Peel the butternut squash and cut it into small cubes (about 1-inch pieces). Or buy the butternut squash precut at your grocery store.
  • Bring a large pot of water to a boil, add the cubed squash, and cook for about 10-15 minutes until the squash is fork-tender. Drain and set aside.
  • In a large skillet, heat the olive oil over medium heat.
  • Add the diced onion and sauté until it turns translucent, about 5 minutes.
  • Add the minced garlic, dried sage, and nutmeg (if using) and sauté for another minute until fragrant.
  • Transfer the cooked butternut squash, sautéed onions, and garlic mixture to a blender.
  • Add the vegetable broth, 1/2 teaspoon salt, and black pepper. Blend until smooth and creamy.
  • If the sauce is too thick, add more broth, a few tablespoons at a time, until you reach your desired consistency.
  • Pour the blended sauce back into the skillet over low heat.
  • Stir in the heavy cream and Parmesan cheese (if using) until melted and well combined.
  • Taste and adjust seasoning with more salt or pepper if needed.
  • If you prefer a touch of brightness, stir in the lemon juice just before serving.
