How to Make Butternut Squash Pasta Sauce
Step 1: Preheat the Oven
Preheat your oven to 450°F (232°C). Line a baking sheet with parchment paper to prevent sticking.
Step 2: Prepare Vegetables
Place the frozen butternut squash cubes, chopped tomatoes, and sliced onion on the baking sheet. Drizzle olive oil over the top and season with salt, black pepper, and dried thyme.

Common Mistakes to Avoid
When making Butternut Squash Pasta Sauce, it’s easy to make a few common mistakes. Here are some tips to ensure your sauce turns out perfectly.

- Not reserving enough pasta water: Reserve at least 1/3 cup of pasta water for blending. This helps achieve a creamy consistency in your sauce.
- Overcooking the pasta: Make sure to follow the package instructions for cooking time. Overcooked pasta can become mushy and won’t hold up well with the sauce.
- Skipping the blending step: For a smooth sauce, blend the roasted vegetables thoroughly. A chunky sauce won’t provide that creamy texture you desire.
- Ignoring freshness: Whenever possible, use fresh tomatoes instead of canned. Fresh ingredients lead to a more vibrant flavor in your sauce.
