Ingredients

• 12 oz spaghetti
• 1 medium (about 2 lbs) butternut squash
• 3 tbsp olive oil
• 3 garlic cloves
• 1 large yellow onion
• 1 tsp fresh thyme leaves
• 0.5 cup Parmesan cheese (optional)
• 1 tsp salt
• 0.5 tsp black pepper
• 0.25 tsp red pepper flakes (optional)

Directions

Step 1

Preheat your oven to 400°F (200°C).

Step 2

Peel and dice the butternut squash into 1-inch cubes. Spread the cubes on a baking sheet lined with parchment paper.

Step 3

Drizzle 2 tablespoons of olive oil over the squash, then sprinkle with 1/2 teaspoon of salt and 1/4 teaspoon of black pepper. Toss to coat evenly.

Step 4

Roast the butternut squash in the oven for 25-30 minutes, turning halfway through, until tender and slightly caramelized.

Step 5

While the squash is roasting, thinly slice the onion and mince the garlic cloves.

Step 6

Bring a large pot of salted water to a boil and cook the spaghetti according to package instructions until al dente. Reserve 1/2 cup of the pasta cooking water, then drain the spaghetti.

Step 7

In a large skillet, heat the remaining 1 tablespoon of olive oil over medium heat. Add the sliced onion and cook for 10-12 minutes, stirring occasionally, until caramelized.

Step 8

Reduce the heat to medium-low and add the minced garlic, fresh thyme leaves, and red pepper flakes (if using). Cook for 1-2 minutes until fragrant.

Step 9

Add the roasted butternut squash to the skillet and gently toss to combine with the onions and seasonings.

Step 10

Add the cooked spaghetti to the skillet, along with a splash of the reserved pasta water. Toss everything together until well mixed and coated. Add more pasta water as needed for a slightly saucy consistency.

Step 11

Taste and adjust seasonings with additional salt or pepper, if needed.

Step 12

Serve warm, topped with grated Parmesan cheese, if desired.
