How to Make Sausage & Butternut Squash Pasta Bake:
Now that you have your ingredients ready, let’s dive into the steps for making this delightful Sausage & Butternut Squash Pasta Bake. It’s as easy as pie, and I promise you’ll feel like a culinary superstar!
Step 1: Roast the Butternut Squash
Preheat your oven to 400°F (200°C). On a parchment-lined baking sheet, toss the cubed butternut squash with 2 tablespoons of olive oil, the maple syrup (if using), 1/2 teaspoon of salt, and 1/4 teaspoon of black pepper. Spread in a single layer and roast for 25-30 minutes, or until tender and caramelized at the edges. Remove from the oven and reduce the oven temperature to 375°F (190°C).
Step 2: Cook the Pasta
While the squash roasts, bring a large pot of generously salted water to a boil. Cook the pasta until it is just shy of al dente, typically about 2 minutes less than the package instructions. It will finish cooking in the oven. Drain the pasta and set it aside.
Step 3: Brown the Sausage and Aromatics
In a large, deep oven-safe skillet or Dutch oven, cook the Italian sausage over medium-high heat, breaking it up with a spoon, until well-browned and cooked through. Use a slotted spoon to transfer the sausage to a plate, leaving the rendered fat in the pan.
Step 4: Sauté the Onion and Herbs
Add the chopped onion to the sausage drippings in the pan. Cook for 5-6 minutes until softened. Add the minced garlic, sage, and thyme and cook for one more minute until fragrant.
Step 5: Create the Roux and Deglaze
Sprinkle the 2 tablespoons of flour over the onion mixture. Cook, stirring constantly, for 1-2 minutes to cook out the raw flour taste. This is your roux. Pour in the white wine (if using) to deglaze the pan, scraping up all the browned bits from the bottom. Let it simmer for 1-2 minutes until the wine has mostly evaporated.
Step 6: Build the Cream Sauce
Gradually whisk in the warm milk and chicken broth, ensuring no lumps form. Bring the mixture to a simmer, stirring constantly, until it thickens slightly, about 3-5 minutes. Stir in the heavy cream and nutmeg. Season the sauce generously with salt and pepper.
Step 7: Assemble the Bake
Remove the skillet from the heat. Stir in the cooked pasta, roasted butternut squash, browned sausage, 1 1/2 cups of the Italian cheese blend, and 1/4 cup of the Parmesan cheese. Stir until everything is evenly coated in the sauce.
Step 8: Add the Topping and Bake
In a small bowl, combine the Panko breadcrumbs, the remaining 1/4 cup of Parmesan cheese, 1 tablespoon of olive oil, and the parsley. Sprinkle this mixture evenly over the top of the pasta bake.
Step 9: Bake to Golden Perfection
Transfer the skillet (or transfer the mixture to a greased 9×13-inch baking dish) to the preheated 375°F (190°C) oven. Bake for 20-25 minutes, or until the sauce is bubbly around the edges and the breadcrumb topping is a deep golden brown. For an extra-crispy top, broil for the last 1-2 minutes, watching closely to prevent burning.
Step 10: Rest and Serve
Let the pasta bake rest for 10 minutes before serving. This allows the sauce to thicken slightly and makes for cleaner portions.
Tips for Success:
-
Undercook the Pasta: This is the golden rule for any pasta bake. The pasta will continue to absorb liquid and cook in the oven, so starting with al dente pasta prevents it from becoming mushy.
-
Use Warm Dairy: Adding warm milk and broth to the roux helps prevent the sauce from becoming grainy and encourages it to thicken smoothly and quickly.
-
Brown the Sausage Well: Don’t just gray the sausage; get a good, deep brown crust on it. This fond (the browned bits) in the pan is packed with flavor for your sauce.
-
Fresh Herbs Make a Difference: While dried herbs work, the floral, pine-like flavor of fresh sage is a game-changer in this dish and pairs exquisitely with the squash.
Equipment Needed:
-
Large, oven-safe skillet or Dutch oven
-
Rimmed baking sheet
-
Large pot for boiling pasta
-
Whisk
-
Cheese grater
-
Measuring cups and spoons
Variations of Sausage & Butternut Squash Pasta Bake:
-
Vegetarian Version: Omit the sausage. Use 8 ounces of sliced cremini mushrooms and sauté them until golden after the onion. The mushrooms provide a wonderful meaty texture and umami depth.
-
Chicken Sausage & Kale: Use a milder chicken apple sausage and stir in 2 cups of chopped, destemmed kale when you combine the pasta and sauce.
-
Goat Cheese & Spinach: Crumble 4 ounces of creamy goat cheese into the sauce just before assembling. Stir in 2 cups of fresh baby spinach along with the pasta; it will wilt in the residual heat.
-
Pumpkin Sauce Version: Replace 1 cup of the milk with 1 cup of canned pumpkin purée for an even more intense, velvety squash flavor.
Serving Suggestions for Sausage & Butternut Squash Pasta Bake:
This is a complete and hearty meal, but a simple side can round it out perfectly.
-
A Crisp Green Salad: A salad with a sharp, lemony vinaigrette (like an arugula salad with shaved Parmesan and lemon) is the ideal palate cleanser.
-
Garlic Bread: Never a wrong choice for sopping up any remaining sauce.
-
Roasted Broccoli or Brussels Sprouts: A side of simply roasted green vegetables complements the rich, cheesy bake beautifully.
-
A Glass of Wine: A medium-bodied white like Chardonnay or a light red like Pinot Noir pairs wonderfully with the savory and sweet elements.

FAQs about Sausage & Butternut Squash Pasta Bake:
Q: Can I make this ahead of time?
A: Absolutely. Assemble the entire bake (through step 7, but wait to add the breadcrumb topping). Cover and refrigerate for up to 24 hours. When ready to bake, let it sit at room temperature for 30 minutes, add the topping, and bake, adding 5-10 minutes to the cooking time.
Q: Can I freeze this pasta bake?
A: Yes, though the texture of the pasta may soften slightly upon reheating. Assemble completely (without the breadcrumb topping), wrap tightly, and freeze for up to 3 months. Thaw in the refrigerator overnight, add the topping, and bake as directed.
Q: My sauce seems too thin before baking. Is that okay?
A: Yes! The uncooked pasta will absorb a significant amount of liquid as it bakes. A slightly loose sauce at the assembly stage is perfect and will result in a creamy, not dry, final dish.
Q: Can I use pre-cubed butternut squash?
A: You can, for a great time-saver. Just be aware that pre-cut squash is often cut into smaller pieces, so reduce the roasting time to 15-20 minutes to prevent it from becoming too soft.
Q: What can I use instead of wine?
A: You can simply omit it. Alternatively, use an additional 1/2 cup of chicken broth with a teaspoon of white wine vinegar or lemon juice added to mimic the acidity.
