Batatas gratinadas com presunto e queijo suíço

Ingredientes

• 2 lbs potatoes, peeled
• 1 medium onion, thinly sliced
• 3 cups chopped ham
• 1/4 cup butter
• 1/4 cup flour
• 3 cups milk
• 1 teaspoon salt
• 1/2 teaspoon pepper
• 1/2 teaspoon dried thyme
• 1/2 teaspoon dry mustard powder
• 8 oz swiss cheese, shredded

Modo de preparo

1. 1

   Preheat oven to 375 degrees. Spray a 3-quart baking dish with cooking spray.

2. 2

   Melt butter over medium heat in a saucepan then whisk in flour. Cook and whisk flour and butter for 2 minutes.

3. 3

   Add salt, pepper, thyme and mustard powder then whisk in milk. Cook and whisk approximately 3-5 minutes or until smooth and thickened. Aim for the thickness of a sauce, not a thick gravy. Remove from heat.

4. 4

   Slice potatoes very thinly (no thicker than 1/8 inch) then add a single layer of potatoes to the bottom of the prepared baking dish.

5. 5

   Layer on 1/3 of the ham and 1/3 of the onions.

6. 6

   Add another single layer of potatoes then repeat the layers twice more, ending with potatoes on top.

7. 7

   Whisk the sauce once again. If it has thickened too much, add a little milk. Again, we’re looking for a sauce, not thick gravy.

8. 8

   Pour sauce evenly over layered ingredients then sprinkle cheese on top.

9. 9

   Bake, uncovered, for 1 hour and 15 minutes, covering loosely with foil when cheese starts to brown.

10. 10

    Remove foil then continue baking for 15-20 minutes longer or until cheese is golden brown and potatoes are tender.
