What Is a Vegetable Casserole?
At its core, a vegetable casserole is a one-dish meal where various ingredients—typically vegetables, grains, proteins, and sauces—are layered or mixed together and baked until golden and bubbling. The beauty of casseroles lies in their adaptability: you can use what’s in season, what’s in your pantry, or what you love most.
In terms of structure, every good casserole includes:
- A base (like pasta, rice, or potatoes)
- A protein (beans, lentils, quinoa)
- Vegetables (choose your favorites or whatever you have on hand)
- A binder (sauces or creamy mixtures to hold it together)
- A topping (cheese, breadcrumbs, or herbs) for crunch and flavor
Why Are Vegetable Casseroles So Popular?
There’s a reason these dishes are loved across generations. Not only do they deliver on taste, but they also meet the needs of modern home cooks.
