  • Total Time: 1 hour 25 minutes
  • Yield: 12 servings

Ingredients

Bacon and Topping

  • 8 slices bacon, diced
  • 2 cups cheddar cheese, shredded

      • Sauce

      • 3 tablespoons butter
      • 1 cup onion, finely diced
      • 3 cloves garlic, minced
      • 3 tablespoons all-purpose flour
      • 2 cups milk
      • 1 cup chicken broth
      • 1 teaspoon salt
      • ½ teaspoon ground black pepper
      • 1 teaspoon dried thyme

      Potatoes

      • 2 pounds potatoes, peeled and thinly sliced

Instructions

  1. Get prepped: Preheat your oven to 400°F (200°C). Peel the potatoes and slice them thinly and evenly, using a mandolin slicer or a sharp knife for best results.
  2. Cook the bacon: Heat a skillet over medium-high heat and cook the diced bacon until crisp. Drain the bacon on paper towels and set aside.
  3. Make the sauce: In a saucepan, melt butter over medium heat. Add the diced onion and cook until softened. Stir in the minced garlic and cook for about a minute, being careful not to burn it.
  4. Add flour: Sprinkle the flour over the butter, onion, and garlic mixture; it will look like wet sand. Cook the mixture until it bubbles.
  5. Whisk in liquids and season: Gradually whisk in the milk and chicken broth. Stir in salt, black pepper, and dried thyme. Continue cooking and whisking until the sauce thickens.
  6. Assemble the casserole: Pour about half a cup of sauce into the bottom of a 9x13 inch casserole dish and spread evenly. Layer potato slices on top, slightly overlapping them. Drizzle more sauce over the potatoes, sprinkle some cheddar cheese and a little bacon.
  7. Repeat layering: Continue layering potatoes, sauce, cheese, and bacon until all ingredients are used, finishing with a top layer of cheese and bacon.
  8. Bake: Place the casserole dish in the preheated oven and bake for 1 hour. Test the potatoes for tenderness by inserting a fork; if not tender, bake for another 10-15 minutes.
  9. Cool and serve: Remove the casserole from the oven and let it cool slightly before serving to allow the sauce to set.
  10. Devour: Enjoy your warm, cheesy potatoes au gratin with crispy bacon!

Notes

  • Use a mandolin slicer to ensure uniform potato slices, which helps them cook evenly.
  • You can substitute milk with half-and-half or cream for an even richer sauce.
  • For a vegetarian version, omit the bacon and use vegetable broth instead of chicken broth.
  • Leftovers can be refrigerated for up to 3 days and reheated in the oven for best texture.
  • If you prefer a crustier top, broil the casserole for 2-3 minutes at the end of baking.
