• Boil the potatoes first until they are tender. Peel and slice them. Toss with salt and pepper.

• Mix olive oil and milk in a small bowl.

• Get a deep baking dish. Arrange onion slices at the bottom. Put some of the sliced potatoes on top in a single layer and then thinly sliced Swiss cheese. Repeat with the remaining potatoes and cheese forming single layers.

• Sprinkle with olive oil and milk mixture and then grated cheddar and oregano.

• Preheat the oven to 400 degrees Fahrenheit.

• Place the baking dish in the oven and bake for 30-35 minutes or until the top is golden.

• Serve immediately.

Bon Appetit!
