1-First Step: Preheat your oven to 400 degrees Fahrenheit; this high heat will help caramelize the butternut squash and herbs for maximum flavor. Gather your 2 cups of cubed butternut squash, 6 to 10 cloves of garlic, 1 shallot, 2 tablespoons of chopped fresh sage, and 1 tablespoon of chopped fresh rosemary, then toss them on a baking sheet with extra virgin olive oil, kosher salt, and black pepper. This step sets the foundation for the dish’s rich, roasted taste, which is key for Roasted Butternut Squash Chicken Pasta lovers.

2-Second Step: Roast the mixture on the baking sheet for about 20 minutes until the squash becomes tender and the garlic caramelizes. Stir halfway through to ensure even cooking; this not only brings out the natural sweetness of the squash but also makes it easy to puree later, adapting well to dietary preferences like low-calorie options by controlling oil amounts.

3-Third Step: Once roasted, transfer the butternut squash, garlic, and shallot to a food processor and puree until smooth. Add one-third cup of heavy cream (or milk for a lighter twist) and one-third cup of grated parmesan cheese, then season with kosher salt and black pepper to taste; blend until creamy. This creates the sauce base, which is versatile for various tastes in Roasted Butternut Squash Chicken Pasta.

4-Fourth Step: Drain 3 tablespoons of oil from the 8-ounce jar of sun-dried tomatoes into a large pot or skillet, then chop the tomatoes and set them aside. Heat the pot over medium-high heat and add 1 pound of boneless skinless chicken breast, 2 tablespoons of Italian seasoning, kosher salt, and black pepper; cook until the chicken turns golden brown, about 5 minutes, and remove it from the pot. This method uses the sun-dried tomato oil for extra flavor, making the chicken tender and infused with herbs.

5-Fifth Step: To the same pot, add 2 tablespoons of salted butter and 1 tablespoon of Italian seasoning; cook for 1 minute until fragrant. Pour in 3 ½ cups of water, bring it to a boil, then add 1 pound of short cut pasta like rigatoni and cook until al dente, about 8 minutes. Stir in the butternut squash puree, two-thirds cup of heavy cream, two-thirds cup of grated parmesan cheese, and the chopped sun-dried tomatoes, then return the chicken and its juices to the pot and toss until everything is creamy and well combined.

6-Sixth Step: Serve the pasta right away, topped with extra grated parmesan cheese and fresh basil for a fresh finish. This final step ensures the dish is piping hot and flavorful, with adaptations for dietary needs like adding spinach for extra nutrients. The whole process, from prep to plate, takes around 45 minutes, fitting perfectly for busy parents and working professionals.
