Common Mistakes to Avoid
When making Butternut Squash Pasta Sauce, it’s easy to overlook a few essential steps. Here are common mistakes and how to avoid them.
- Boldly skip the seasoning: Not seasoning your vegetables can lead to bland sauce. Always season with salt, pepper, and herbs for flavor.
- Boldly ignore pasta water: Forgetting to reserve pasta water means missing out on a creamy texture. Always save some before draining the pasta.
- Boldly rush the baking: Undercooking the vegetables can result in a chunky sauce. Ensure they are roasted until tender for a smooth blend.
- Boldly blend cold ingredients: Blending veggies straight from the fridge will cool down your sauce. Use them hot from the oven for the best consistency.
- Boldly serve without toppings: Skipping cheese or plant-based alternatives can reduce overall flavor. Add parmesan or plant-based parm for a delicious finish.
