Swiss Chard Gratin

Ingredients

• 1 potato, peeled (about 5 ounces/150 grams)
• 2 tablespoons butter
• 1/4 cup diced onion
• 1 garlic clove, minced
• 1/4 cup all-purpose flour
• 1 3/4 cups milk
• 1/4 teaspoon cayenne pepper
• 1/2 teaspoon dry mustard
• 1 pinch salt, pepper, ground nutmeg
• 1/3 cup gruyere cheese, shredded
• 3 tablespoons parmesan cheese, grated
• 2 1/2 cups swiss chard, shredded

Directions

1. 1

   In a small saucepan of boiling salted water, cook potato until tender, 10-12 minutes. Alternatively, cook potato in microwave until tender. Let cool for 5 minutes. Slice thinly and overlap in a greased small shallow gratin (casserole) dish.

2. 2

   In a small saucepan, heat butter over medium heat; cook onion and garlic until softened, about 3 minutes. Stir in the flour; cook for 1 minute. Whisking constantly, add milk, 1/2 cup at a time. Whisk in cayenne pepper, mustard, salt, pepper and nutmeg to taste. Reduce heat to low; simmer, whisking occasionally, until thickened, 5-7 minutes. Stir in Gruyere and Parmesan cheeses.

3. 3

   Pour 1/2 cup of sauce over potato. Top with Swiss chard, pressing to compact. Pour remaining sauce over top. Bake in a 400 F oven for 20-25 minutes or until bubbly and browned.
