- 1 pound broccoli cut into florets (about 6 cups)
- Water about 1 cup, for steaming
- 2 tablespoons butter
- 2 tablespoons flour
- 1 cup milk I used 1%, but any works
- ⅔ cup shredded cheddar cheese
- 2 tablespoons grated Parmesan cheese
- ¼ teaspoon kosher salt plus extra to taste
- Pinch ground mustard optional, for depth
- Pinch cayenne pepper optional, for a subtle kick
Tip: Use sharp cheddar for a bold, tangy sauce or mild cheddar for a kid-friendly version. Parmesan adds extra depth, but Gruyère or mozzarella work beautifully too.
