Tips
Reserve pasta cooking water before draining; the starch helps emulsify and thicken the carrot puree sauce.
Stir the sauce frequently to prevent sticking and ensure even thickening.
Let the finished dish rest for 5 minutes so the cheese sets slightly and it becomes easier to serve.
Good to Know
Cover and refrigerate up to 3 days. Reheat gently in a 350 degree F oven, covered, for 15 minutes.
Assemble the baking dish through the breadcrumb topping up to 4 hours ahead. Refrigerate covered and bake when ready, adding 5 extra minutes to baking time if cold.
Serve directly from the baking dish or plated warm. Pairs well with a simple green salad or steamed broccoli.
Common Mistakes
Do not skip reserving pasta water; without it, the sauce will not thicken properly and will be too thick.
