Ingredients
  

For the Gratin
  • 2 lbs potatoes (Russet or Yukon Gold) Peeled and thinly sliced
  • 4 strips turkey bacon Cooked and chopped
  • 1 cup mushrooms, sliced (button or cremini) Sautéed until golden brown
  • 3 cloves garlic, minced Added during the last minute of sautéing mushrooms
  • 1 cup heavy cream Combined with the cheese for the sauce
  • 1 cup grated cheese (cheddar, Gruyère, or your favorite) Half for the cream sauce, half for topping
  • 2 tbsp butter Dotted on top before baking
  • to taste Salt and pepper For seasoning
  • to taste Fresh parsley, chopped For garnish

Method
 

Preparation
  1. Preheat your oven to 375°F (190°C).
  2. Peel and thinly slice the potatoes to about 1/8-inch thick.
  3. In a skillet over medium heat, cook the turkey bacon until crispy. Remove and chop into bite-sized pieces.
  4. In the same skillet, sauté the sliced mushrooms until golden brown, about 5-7 minutes. Add minced garlic during the last minute.
  5. In a bowl, combine heavy cream, half of the cheese, salt, and pepper, whisk until blended.
Assembly
  1. In a greased baking dish, layer half of the potato slices, followed by half of the mushroom-garlic mixture and turkey bacon. Pour half of the cream mixture over the top. Repeat layers with remaining ingredients.
  2. Sprinkle the remaining cheese on top and dot with butter.
Baking
  1. Cover the dish with aluminum foil and bake for 45 minutes. Remove foil and bake for an additional 15 minutes until golden brown and bubbling.
  2. Let it cool for a few minutes, then garnish with fresh parsley before serving.

Notes

Don’t stress about slicing; uneven slices will still taste amazing. Substitute turkey bacon with regular bacon or skip for a vegetarian version. This gratin reheats beautifully making it great for meal prep.
