Common Mistakes to Avoid

- Using frozen squash without thawing – Always thaw your frozen butternut squash before baking. This ensures even cooking and better blending.
- Overcooking the vegetables – Keep an eye on the baking time. Overcooked veggies can lose their flavor and texture, leading to a less appealing sauce.
- Not reserving enough pasta water – Remember to save at least 1/3 cup of pasta water. This starchy liquid helps achieve a creamy consistency in your sauce.
- Skipping seasoning adjustments – Taste your sauce after blending and adjust the seasonings as necessary. A pinch more salt or pepper can elevate the flavor dramatically.
- Neglecting to blend thoroughly – Ensure you blend until smooth for a creamy texture. Chunky sauce can distract from the overall experience of the dish.
