Autumn on a Plate: Roasted Butternut Squash and Brussels Sprout Rigatoni with Crispy Bacon 🍁🥓🍝

There is a specific time of year when the air turns crisp, the leaves begin to change, and our cravings shift from light summer salads to hearty, comforting bowls of warmth. This recipe for Roasted Butternut Squash and Brussels Sprout Rigatoni with Crispy Bacon is the quintessential embodiment of that season. It captures the essence of autumn in every bite, combining the earthy sweetness of caramelized squash with the nutty, slightly bitter char of roasted Brussels sprouts, all balanced by the savory, salty crunch of crispy bacon.

As pictured in the beautiful image above, this isn’t a pasta drowning in a heavy cream or tomato sauce. Instead, it relies on a “no-sauce” sauce technique, utilizing the rendered bacon fat, high-quality olive oil, starchy pasta water, and Parmesan cheese to create a glossy, savory coating that lets the roasted vegetables shine as the stars of the show. It’s a rustic, sophisticated, and incredibly satisfying meal perfect for a cozy weeknight dinner or casual entertaining.

The Art of the Roast: Achieving Maximum Flavor 🔥

The success of this dish hinges entirely on how you treat the vegetables. Boiled or steamed Brussels sprouts and squash will not work here; they will turn mushy and bland. Roasting at high heat is essential to develop the complex flavors and textures seen in the photo.

The Maillard Reaction: You want the vegetables to undergo the Maillard reaction—a chemical reaction between amino acids and reducing sugars that gives browned food its distinctive flavor. For the butternut squash, this means the natural sugars will caramelize, creating sweet, golden-brown edges that are tender on the inside.

Embracing the Char: For the Brussels sprouts, do not fear the char! The blackened leaves on the outside of the sprouts, as clearly visible in the image, provide a crucial smoky, slightly bitter counterpoint to the sweet squash and salty bacon. To achieve this, ensure your sprouts are perfectly dry before tossing them with oil, and arrange them cut-side down on the baking sheet. Don’t overcrowd the pan, or they will steam instead of roast. Give them space to breathe and brown.

The Salty Foundation: Bacon and Its “Liquid Gold” 🥓

While the vegetables provide the bulk and the autumnal flavor profile, the bacon provides the savory backbone. We don’t just want the crispy bits of meat; we want the rendered fat.

Starting the bacon in a cold pan and letting it cook slowly allows the fat to render out completely, leaving you with unbelievably crispy lardon pieces. The resulting fat left in the pan is “liquid gold.” It is infused with smoky, salty flavor and serves as the base for sautéing the garlic and eventually coating the pasta. This fat is what bridges the gap between the pasta dough and the roasted toppings, ensuring every bite is cohesive and flavorful. If you prefer pancetta, it works equally well here, offering a slightly more cured, less smoky flavor.

The “No-Sauce” Sauce Technique 🥄

Many home cooks are intimidated by pasta dishes that don’t have a jarred sauce. How does it not taste dry? The secret lies in the marriage of fat, starch, and cheese.

By reserving a cup of the cloudy, starchy water the pasta cooked in, you have a powerful emulsifier at your disposal. When you toss the hot pasta with the rendered bacon fat and olive oil, adding splashes of that starchy water creates an emulsion—a creamy, glossy liquid that clings to the rigatoni. Adding finely grated Parmesan cheese to this hot mixture causes it to melt into the emulsion, thickening it slightly and adding an umami punch.

The result is a light yet rich coating that flavors the pasta without masking the roasted vegetables. The fresh thyme added at the end, as seen garnishing the bowl, provides a necessary herbal lift that brightens the heavier flavors.

Ingredients 🛒

To recreate this cozy, rustic pasta dish at home, gather the following ingredients.

• 1 pound Rigatoni pasta (or another tube shape like penne or mezze maniche)
• 4 cups butternut squash, peeled and diced into 1-inch cubes
• 1 pound Brussels sprouts, trimmed and halved lengthwise
• 6 thick-cut slices of bacon, chopped into 1-inch pieces
• 3 tablespoons olive oil, divided
• 3 cloves garlic, thinly sliced
• 1/2 teaspoon red pepper flakes (optional, for heat)
• 1 cup freshly grated Parmesan cheese, plus more for serving
• 2 tablespoons fresh thyme leaves, plus whole sprigs for garnish
• Kosher salt and freshly cracked black pepper, to taste
• 1 cup reserved pasta water

Instructions 👨‍🍳👩‍🍳

Follow these steps to achieve the perfectly roasted vegetables and glossy pasta seen in the photo.

1. Preheat and Prep: Preheat your oven to 400°F (200°C). Line two large baking sheets with parchment paper for easy cleanup.
2. Roast the Squash: On one baking sheet, toss the cubed butternut squash with 1 tablespoon of olive oil, 1/2 teaspoon of salt, and 1/4 teaspoon of black pepper. Spread them in a single layer. Roast for 25-30 minutes, flipping halfway through, until tender and caramelized on the edges.
3. Roast the Sprouts: While the squash roasts, toss the halved Brussels sprouts on the second baking sheet with 1 tablespoon of olive oil, salt, and pepper. Arrange them cut-side down. Roast for 20-25 minutes until tender and deeply browned (charred) on the cut sides.
4. Crisp the Bacon: While the vegetables are roasting, place the chopped bacon in a large, cold skillet or Dutch oven. Turn the heat to medium and cook slowly, stirring occasionally, until the fat has rendered and the bacon is crispy (about 10-12 minutes). Remove the bacon with a slotted spoon to a paper towel-lined plate, leaving roughly 2 tablespoons of the rendered fat in the pan. (Discard excess or save for another use).
5. Cook the Pasta: Bring a large pot of heavily salted water to a boil. Add the rigatoni and cook according to package directions until just al dente. Do not overcook. Crucial Step: Before draining, carefully dip a mug into the pot and reserve roughly 1 cup of the starchy pasta cooking water. Drain the pasta.
6. Build the Flavor Base: Return the skillet with the bacon fat to medium heat. Add the sliced garlic and red pepper flakes (if using). Cook for just 1 minute until fragrant, being careful not to burn the garlic.
7. Combine and Emulsify: Add the drained pasta directly to the skillet with the garlic and fat. Toss to coat. Add the roasted squash, roasted Brussels sprouts, crispy bacon, fresh thyme leaves, and half of the Parmesan cheese.
8. Create the Sauce: Drizzle in about 1/4 cup of the reserved pasta water. Toss vigorously over low heat. The water, fat, and cheese should emulsify into a glossy coating. If it seems dry, add more pasta water a tablespoon at a time until it reaches your desired consistency.
9. Season and Serve: Taste and season generously with lots of freshly cracked black pepper and salt if needed (the bacon and cheese add salt, so taste first). Serve immediately in bowls, topped with extra Parmesan cheese and fresh thyme sprigs as shown in the image.

Variations and Substitutions 🔄

This recipe is highly adaptable to your dietary needs or what you have in your pantry.

• Make it Vegetarian: Omit the bacon entirely. To replace the savory depth, sauté sliced mushrooms (like cremini or shiitake) in olive oil until deeply browned before adding the garlic in step 6. Add a splash of soy sauce or miso paste to the sauce for extra umami.
• Change the Pasta: While rigatoni is excellent for catching the small bits of bacon and cheese, other short shapes work well. Try orecchiette, fusilli, or farfalle.
• Add Nuts: For an extra textural crunch that complements the squash, toss in 1/4 cup of toasted pine nuts, chopped walnuts, or pecans just before serving.
• Herb Swap: If you don’t love thyme, fresh sage is a wonderful alternative that pairs beautifully with butternut squash. Fry whole sage leaves in the bacon fat for a crispy garnish.
