Preparation Phase & Tools to Use

For this dish, you’ll need a few essential tools to get the best results:

• Sharp Chef’s Knife & Cutting Board: Crucial for safely and efficiently dicing the butternut squash.
• Large Skillet or Sauté Pan: A wide pan allows the butter to brown evenly and gives the squash space to caramelize instead of steam.
• Medium Pot: For boiling the pasta — make sure it’s large enough to allow the pasta to cook evenly.
• Slotted Spoon or Spider: Helps transfer pasta directly into the sauce while saving pasta water.
• Wooden Spoon or Silicone Spatula: Ideal for stirring the sauce and scraping up browned bits from the pan.

Each tool serves a purpose: precise chopping, optimal sautéing, and easy combining. Don’t skip the wide skillet — it’s key for browning the butter without burning.

Preparation Tips

To make the most of this recipe, start with pre-peeled and cubed butternut squash if you’re short on time. Roast the squash instead of sautéing for deeper caramelization and added sweetness. Don’t rush the butter — let it brown slowly until it smells nutty and turns golden with specks of brown. And finally, always reserve a cup of pasta water to loosen and bind the sauce. This starchy liquid transforms the dish from just pasta and toppings into a velvety, cohesive plate of flavor.

Ingredients for this Brown Butter Sage Butternut Squash Pasta

• 12 oz rigatoni or short pasta of choice
• 3 cups butternut squash, peeled and diced into 1/2-inch cubes
• 6 tbsp unsalted butter
• 10-12 fresh sage leaves
• 3 garlic cloves, minced
• 1/2 tsp crushed red pepper flakes (optional, for a hint of heat)
• Salt and black pepper to taste
• 1/2 cup grated Parmesan cheese (plus more for serving)
• 1/2 cup reserved pasta water (adjust as needed)
• 2 tbsp olive oil (for roasting squash)

---

Step 1: Roast the Butternut Squash

Preheat your oven to 425°F (220°C). Toss the diced squash with olive oil, a generous pinch of salt, and black pepper. Spread evenly on a baking sheet and roast for 25-30 minutes, flipping once halfway through, until the squash is tender and golden-brown around the edges. Set aside.

---

Step 2: Cook the Pasta

Bring a large pot of salted water to a boil. Cook the rigatoni according to package instructions until al dente. Before draining, reserve about 1 cup of pasta water. Drain the pasta and set aside.

---

Step 3: Brown the Butter with Sage

While the pasta cooks, melt butter in a large skillet over medium heat. Add the sage leaves and cook until the butter foams and turns golden brown, and the sage becomes crisp (about 4-5 minutes). Stir constantly to prevent burning. Remove the sage leaves and set aside on a paper towel.

---

Step 4: Build the Sauce

To the browned butter, add minced garlic and crushed red pepper flakes (if using). Sauté for 30 seconds until fragrant. Add the roasted butternut squash and gently toss to coat. Let it warm through for 2-3 minutes.

---

Step 5: Combine Pasta and Finish

Add the drained pasta directly into the skillet with the squash and sauce. Pour in 1/4 cup of reserved pasta water and sprinkle in the Parmesan cheese. Stir and toss everything together over medium-low heat until the cheese melts and the sauce coats the pasta. Add more pasta water as needed for creaminess.

---

Step 6: Garnish and Serve

Serve hot, topped with the crispy sage leaves and extra Parmesan. Finish with freshly ground black pepper and a drizzle of olive oil if desired. This pasta is best enjoyed immediately while the sauce is creamy and the sage is crisp.

Notes

This pasta dish thrives on contrast — rich brown butter, tender squash, and crispy sage come together beautifully. Roasting the squash rather than sautéing gives it a deeper flavor and a subtle sweetness that balances the savory elements. Don’t rush the butter browning process; that nutty aroma is what makes the sauce so special. Use freshly grated Parmesan if possible, as it melts more smoothly and adds a punch of umami.

Watch Out for These Mistakes While Cooking

• Overcrowding the squash on the baking sheet: This causes steaming instead of roasting. Give the cubes space for proper caramelization.
• Burning the butter: Brown butter can quickly turn from golden and nutty to bitter and blackened. Stir continuously and remove from heat once it’s browned.
• Skipping the pasta water: This starchy liquid is essential for emulsifying the sauce and helping it cling to the pasta.
• Adding cheese while the heat is too high: It can clump. Lower the heat and stir constantly while adding cheese.
• Not seasoning in layers: Taste and adjust salt and pepper throughout the process for best flavor.

Storage Instructions

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or microwave with a splash of water or broth to loosen the sauce. The sage won’t stay crisp, so it’s best to fry a fresh batch if you’re planning to serve it again. Freezing is not recommended, as the texture of the squash and pasta can become mushy.
