2 pounds russet potatoes, scrubbed, peeled
1 medium yellow onion
1 1/2 cups heavy whipping cream
1 teaspoon minced garlic
½ teaspoon salt
¼ teaspoon pepper
¼ teaspoon dried rosemary
Preheat oven to 350 degrees Fahrenheit
Using a paper towel with a little oil on it, grease 8 x 8 baking dish. You can also just use cooking spray to lightly spray baking dish.
Mix salt, pepper and rosemary together in a small bowl.
Using a Mandoline Slicer or food processor slice potatoes and onions thinly. Layer a third of the onions, garlic, and potatoes on the greased baking dish. Sprinkle with 1/3 of the rosemary seasoning mix. Pour over the top 1/3 of the cream.
Repeat two more times. Bake uncovered for 1 hour or until the potatoes are cooked through and are pleasantly golden browned. Serve right away. Enjoy.
