This cheesy cauliflower casserole is the ultimate comfort food! It is made with 1 whole head of chopped cauliflower florets, shredded cheddar cheese, and frozen corn, for convenience. Bake until brown edged and bubbling! It’s an extra easy vegetable dish or veggie-loaded dinner, and ready in just 50 minutes.
Bring a large pot of water to a boil. Add cauliflower and boil for 5 minutes, allowing the cauliflower to soften. With 1 minute remaining, add the frozen corn. Drain the vegetables and place in a 11x8 baking dish.
In a medium-sized saucepan add butter over medium high heat. Add flour, stirring until completely smooth. Add milk and 1/2 cup of cheese and continue stirring until cheese is melted and sauce thickens up.
Pour cheese sauce over vegetables, mixing so the cheese covers everything. Sprinkle salt and pepper on top to taste. Sprinkle 1 cup remaining cheddar cheese on top.
Place in oven and bake for 30 minutes. Optional: After 30 minutes, turn oven to broil and bake (while watching it carefully) for 2-3 minutes, or until cheese is lightly browned. Serve and enjoy!
