Ingredients

  • 12 baby red potatoes any variety potato, peeled and cut into 1/2-inch cubes
  • 3 tbsp olive oil
  • 1 yellow onion chopped
  • 3 cloves garlic minced
  • 1 tsp salt
  • 1 tsp pepper
  • 1/2 cup milk
  • 8 oz sour cream
  • 2 cups cheddar cheese shredded, divided
  • 1/2 cup bacon cooked and chopped
  • 1 bunch green onions thinly sliced

Instructions

  • Preheat oven to 375 degrees F. Coat a 9×13 baking dish with cooking spray and set aside.
  • Boil potatoes in a large saucepan for 20 minutes, or until a fork can be easily inserted into the centers. Drain and return to saucepan. Meanwhile, heat the olive oil in a skillet over medium heat. Add onion, garlic, salt and pepper, and cook for 3 minutes, or until the onion is soft and fragrant.
  • Add the onion mixture to the potatoes, along with milk, sour cream and 1 1/2 cups cheese. Stir until combined.
  • Pour into the prepared baking dish and spread in an even layer and top with the remaining 1/2 cup cheese. Sprinkle bacon and green onions over the top and bake in the preheated oven for 20 minutes.

Notes

 
  • Use any variety of potatoes for this recipe. Russet, gold, yukon and red all work great.
  • Use 3 large potatoes, 5 medium potatoes or 10-12 baby potatoes for this casserole.
  • Go as crazy with the toppings as you'd like. Anything that tastes great on a baked potato (such as chives) will also taste amazing in this potato casserole!
  • After baking, consider adding extra toppings such as extra shredded cheddar cheese and sour cream.
