My mom made this broccoli cheese casserole every Thanksgiving when I was little. We kids could never get enough! If you have children or have some coming to visit you as guests this Thanksgiving, I guarantee that they will eat (and enjoy) this veggie dish. It's also fabulous with a Christmas ham.
For enhanced flavor, consider sautéing the chopped onion before adding it to the mixture, allowing it to soften and sweeten. To prevent a watery casserole, ensure the frozen broccoli is thawed and well-drained, though some moisture can be absorbed by the cheese sauce. A sprinkle of breadcrumbs or crushed crackers mixed with melted butter can be added on top during the last 15 minutes of baking for an extra crispy texture. For a richer cheese flavor, use a blend of sharp Cheddar and a touch of Parmesan or Gruyère. Always taste and adjust seasoning (salt and pepper) before baking.
