This potato, carrot, and broccoli casserole combines tender vegetables with a creamy homemade cheddar sauce and a golden layer of melted cheese. The potatoes make it hearty, carrots add a touch of sweetness, and broccoli brings color and texture to every serving.
The vegetables are partially cooked before baking so they become tender at the same time without the broccoli turning too soft. Serve the casserole as a comforting vegetable main dish or as a hearty side for a family dinner.

Notes
Partially cooking the potatoes and carrots before baking ensures all the vegetables become tender at the same time.
Don't overcook the broccoli before baking so it maintains its texture and color.
Gruyère, mozzarella, or Monterey Jack can replace the cheddar.
Add breadcrumbs to the top before baking for an extra crispy finish.
