What is a Vegetable Bake?

A vegetable bake is a dish that combines fresh or pre-cooked vegetables, seasonings, and often a creamy or cheesy sauce, then bakes them in the oven until tender and golden. It’s a staple in many cuisines because it can be adjusted for dietary needs and seasonal availability.
