Ingredients
Method
- Heat the oven to 375°F (190°C). Grease a 9-by-13-inch baking dish.
- Steam or blanch broccoli for 2 minutes, then drain well.
- Melt butter in a saucepan. Whisk in flour for 1 minute, then gradually whisk in milk. Cook until slightly thickened. Stir in mustard, garlic powder, salt, pepper, and 1 cup cheese.
- Layer half the potatoes, broccoli, and sauce in the dish; repeat. Cover tightly with foil and bake for 35 minutes.
- Uncover, add remaining cheese, and bake for 10 to 15 minutes, until bubbling and the potatoes are tender. Rest for 10 minutes.
