6. Tips
- Use a mix of cheeses like fontina, Monterey Jack, or smoked gouda for deeper flavor.
- Roast the broccoli and cauliflower in the oven instead of steaming for a more caramelized taste.
- Add cooked chicken, ham, or bacon for extra protein.
- For a lighter option, replace half the milk with low-fat milk or broth.
- Prepare ahead by assembling the casserole and refrigerating; just bake before serving.
