Common Mistakes to Avoid
When making Butternut Squash Pasta Sauce, it’s easy to overlook some key steps that can affect the final result. Here are common mistakes to avoid.
- Using frozen squash without thawing: Not allowing the squash to thaw can lead to uneven cooking. Always preheat and ensure even roasting.
- Skipping the blending step: Failing to blend the roasted vegetables properly can result in a chunky sauce instead of a creamy texture. Blend until smooth for the best results.
- Not reserving enough pasta water: Forgetting to save enough pasta water can make the sauce too thick. Reserve at least 1/3 cup to achieve the right consistency.
- Overcooking the pasta: Cooking pasta longer than recommended can result in mushy noodles. Follow package instructions for al dente perfection.
- Neglecting to season well: Lacking flavor from seasoning will lead to a bland sauce. Taste and adjust salt and pepper before serving.
