Step‑by‑Step Instructions for Creamy Butternut Squash Pasta with Sausage and Spinach

Step 1: Preheat and Prepare the Squash
Begin by preheating your oven to 400°F (200°C). While the oven heats, peel, seed, and cube your butternut squash into bite-sized pieces. This vegetable will add a deliciously sweet and creamy element to your Butternut Squash Pasta. Place the cubed squash in a large bowl and drizzle with olive oil, salt, and pepper, tossing until evenly coated.

Step 2: Roast the Squash
Spread the seasoned butternut squash evenly on a baking sheet lined with parchment paper. Roast in the preheated oven for 20–25 minutes, or until the squash is tender and caramelized, stirring halfway for an even cook. You'll know it's ready when it turns golden brown and feels fork-tender, creating a beautiful base for your pasta dish.

Step 3: Brown the Sausage
While the squash is roasting, heat a tablespoon of olive oil in a large skillet over medium heat. Add the Italian sausage and cook for about 5–7 minutes, breaking it apart with a spatula until browned and cooked through. This step brings a savory depth of flavor essential for your creamy Butternut Squash Pasta. Once done, remove the sausage from the skillet and set aside.

Step 4: Sauté the Aromatics
In the same skillet, add another splash of olive oil if needed, and toss in the diced onion. Sauté for approximately 5 minutes, stirring occasionally, until it softens and becomes translucent. Then, add the minced garlic and cook for an additional minute until fragrant, ensuring your kitchen fills with mouthwatering aromas that complement the squash and sausage.

Step 5: Cook the Spinach
Next, add the baby spinach to the skillet, stirring it in with the onions and garlic. Cook for about 2–3 minutes, or until the spinach wilts down significantly. This vibrant greens layer will bring freshness to your Butternut Squash Pasta and balance the dish with its nutrients. Once wilted, turn off the heat and set the mixture aside.

Step 6: Boil the Pasta
In a large pot, boil salted water over high heat and cook your choice of pasta according to package directions, typically 8–10 minutes for al dente texture. Remember to reserve about a cup of pasta water before draining it to help adjust the sauce’s consistency later. Draining pasta at the right time will ensure it maintains its perfect bite.

Step 7: Combine the Roasted Ingredients
Once your butternut squash is roasted, optionally purée it for a smoother sauce if desired. In the skillet with the sausage, spinach, garlic, and onions, combine in the roasted squash. Stir everything together well, allowing the flavors to meld beautifully for your creamy Butternut Squash Pasta.

Step 8: Create the Creamy Sauce
Pour in the heavy cream and add any desired seasonings, including dried sage, salt, pepper, and red pepper flakes. Gradually mix in the reserved pasta water, adjusting until the sauce reaches your desired creamy consistency. The combination of all these elements creates a rich, comforting sauce that envelops the pasta perfectly.

Step 9: Toss in the Pasta
Finally, add the drained pasta to the skillet and toss to coat it thoroughly with the rich, creamy sauce. Let everything simmer on low heat for a minute to warm through and meld the flavors. Don’t forget to sprinkle in freshly grated Parmesan cheese, allowing it to melt into the dish for a final touch of umami goodness.

Step 10: Serve and Enjoy
Serve your creamy Butternut Squash Pasta with Sausage and Spinach warm, garnished with additional Parmesan and perhaps a sprinkle of fresh herbs or red pepper flakes for some extra flair. Enjoy this hearty, comforting dish with family and watch them relish every savory bite!

What’s the best way to store leftovers?
Store your creamy butternut squash pasta in an airtight container in the refrigerator for up to 3 days. Allow the pasta to cool completely before sealing to maintain its freshness.

What should I do if my sauce is too thick?
If your sauce ends up too thick, don't fret! Simply add a bit of the reserved pasta water, a tablespoon at a time, stirring until you reach your desired consistency. This water is starchy, helping to create a silky sauce that clings perfectly to your pasta.

Is this recipe suitable for people with allergies?
Take care! If you're making this dish for someone with allergies, ensure to check labels on the sausage and other ingredients for possible allergens. For a nut-free version, be cautious with any toppings, such as nuts. You can easily customize it with your favorite ingredients, like using chickpeas instead of sausage for a vegetarian option.
