There are a few boxes that I need checked when it comes to making the perfect scalloped potatoes. Number one? The consistency of the potatoes. The worst is when they are undercooked, so timing and testing before pulling them out of the oven is everything.

Secondly, the flavor. Lastly... creaminess. If you can nail all three, you have a winner. This recipe promises the possibility of all three.

  • 6 potatoes, medium size, gold potatoes. (Approximately 5 cups sliced)
  • ⅓ cup Sweet Onions, chopped
  • ⅓ cup Bacon Bits
  • 3 tablespoons Butter (I used unsalted, but you can use salted)
  • 3 tablespoons Unbleached All-Purpose Flour
  • 1 cup Whole Milk
  • 1 can (10.5 oz.) Cream of Mushroom Soup
  • 1 teaspoon Celery Seeds
  • 1 teaspoon Garlic Powder
  • 1 teaspoon Salt
  • ½ teaspoon Ground Pepper
  • ½ cup Sour Cream
  • 1 cup Shredded Colby Jack
  • 1 cup Shredded Mild Cheddar

Preheat the oven to 350 degrees F
Butter or use Non-Stick Cooking Spray to coat a 9 x 9 baking dish. Set aside.
Clean the potatoes, peel, and slice them approximately ⅛ to ¼ inch thick. You can use a Mandolin or do it with a knife. I used a chef knife.
Put the sliced potatoes in a medium-size bowl filled with cold water. Putting them in cold water when they are sliced prevents them from browning and helps get some of the starch out. Set aside.
In a medium-size saucepan, add the bacon bits and the chopped onions.
Add the butter and mix until the butter is melted over medium heat.
Add the flour and whisk until all blended and you have a thick mixture.
Add the milk and the cream of mushroom soup. Whisk, over medium heat, until all combined. You will have a thick sauce.
Add the spices and mix until incorporated
Take off the heat and add the sour cream. Mix until all combined. Set aside.
Take the sliced potatoes out of the water. Pat dry, and place approximately ⅓ of the potatoes in the coated baking dish.
Sprinkle some shredded cheese over the potatoes. About ½ cup.
Add ½ of the milk mixture, spread evenly.
Add ⅓ of the sliced potatoes
Add about ½ cup shredded cheese
Add the remaining milk mixture.
Add the remaining of the potatoes
Sprinkle it with the remaining cheese.
Bake uncovered, in preheated oven for 50 to 60 minutes
Bake until it is golden, and the potatoes are nice and tender.
Serve and enjoy
  • Excellent side dish to serve with chicken breast, sausage, steak.
  • If made ahead of time, you can warm them up by putting them back in the oven at 325 degrees F for 10 minutes or until desired heat.
