Ingredients for Au Gratin Potatoes and Ham
- Potatoes: The best way to slice potatoes for au gratin potatoes is using a mandoline slicer. These handheld tools can produce very thin slices, and they ensure all the potatoes are cut to an even width. To keep the potato slices from oxidizing and turning brown as you work, store the slices in water until you’re ready to cook.
- Cooked ham: Any type of cooked ham works here. You can use sliced ham from the deli, ham steak, or leftover honey baked ham or bourbon-glazed ham from a holiday dinner.
- Cheese sauce: The cheesy sauce in this recipe is made with butter, all-purpose flour, milk and shredded cheddar.
Directions
Step 1: Begin layering the gratin
Preheat the oven to 350°F. In a greased 1-quart baking dish, combine the cooked potatoes, ham and onion. Set aside.
Editor’s Tip: There are several ways to cook potatoes, but the microwave is a good option here. Peel and slice the potatoes. Place them in a microwave-safe bowl with 1 tablespoon water. Partially cover the bowl. Microwave for three minutes, or until softened.
Step 2: Make the cheese sauce
In a saucepan, melt the butter over medium heat. Stir in the flour until smooth. Gradually add the milk. Bring the mixture to a boil. Cook and stir for two minutes, until the mixture is thickened and bubbly.
Add the cheese, salt and pepper. Stir until the cheese is melted.
Pour the cheese sauce over the potato mixture, and stir gently to mix.
Step 3: Bake the gratin
Bake, uncovered, for 35 to 40 minutes or until bubbly. Garnish with parsley, and serve.
