The perfect balance of tender potatoes, melted cheese, and smoky crunch makes this recipe an irresistible favorite.

Ingredients

6 cups Russet or Yukon Gold potatoes, peeled and diced

1 cup sharp cheddar cheese, shredded

¾ cup mayonnaise

1 cup turkey bacon, cooked until crispy and crumbled

3 teaspoons garlic, minced

½ cup onion, finely chopped

Salt and black pepper, to taste

Cooking spray or butter for greasing pan

Instructions

  • Preheat oven to 325°F (163°C). Lightly grease a 9×13-inch baking dish with cooking spray or butter.

  • Cook turkey bacon in a skillet until crisp. Drain on paper towels and crumble.

  • Prepare the potatoes: Peel and dice them into ½-inch cubes. Rinse and drain well to remove excess starch.

  • In a large mixing bowl, combine diced potatoes, shredded cheddar cheese, crumbled turkey bacon, minced garlic, and chopped onions.

  • Add mayonnaise to the bowl and gently stir everything together until the potatoes are evenly coated.

  • Transfer the mixture to the prepared baking dish. Spread it evenly.

  • Bake uncovered for 1 hour and 30 minutes, or until the potatoes are fork-tender and the top is golden and bubbling.

  • Optional: Sprinkle extra cheese or chopped green onions on top during the last 10 minutes of baking for added flavor and color.

  • Let rest for 5–10 minutes before serving to help it firm up.

Notes

  • For a lighter version, substitute half of the mayo with plain Greek yogurt or light sour cream.

  • If you prefer a crispier texture, broil the dish for the last 2–3 minutes.

  • Use Yukon Gold for a creamier texture or Russet for a fluffier finish.

  • Add chopped green onions, bell peppers, or jalapeños for extra flavor.

  • Can be made vegetarian by omitting turkey bacon or replacing it with a meatless alternative.
