Ingredients
- 8 oz, grated sharp cheddar cheese
- 3 tbsp unsalted butter
- 3 tbsp all-purpose flour
- 1 tsp dry mustard powder
- 1 tbsp Worcestershire sauce
- 1 cup whole milk
- 1/2 tsp salt
- 1/4 tsp black pepper
- 6 thick slices, toasted bread slices
Instructions
- Step 1: Preheat your oven broiler to high. In a medium saucepan, melt 3 tbsp unsalted butter over medium heat until foaming.
- Step 2: Stir in 3 tbsp all-purpose flour and 1 tsp dry mustard powder, whisking continuously for 2 minutes to form a roux without browning.
- Step 3: Gradually whisk in 1 cup whole milk, continuing to stir until the sauce thickens and coats the back of a spoon, about 5 minutes.
- Step 4: Remove the saucepan from heat and stir in 8 oz grated sharp cheddar cheese, 1 tbsp Worcestershire sauce, 1/2 tsp salt, and 1/4 tsp black pepper until smooth.
- Step 5: Arrange 6 thick toasted bread slices on a baking sheet. Spoon the cheese sauce evenly over the toast, spreading to cover.
- Step 6: Place under the broiler for 3-4 minutes until the cheese sauce bubbles and develops golden brown spots.
- Step 7: Remove from oven and serve immediately with a crisp green salad.
