How to make Creamy Cheddar and Bacon Hasselback Potato Gratin

Assembly the following ingredients.

  • Yukon gold potatoes – Yukon golds crisp up fabulously when baked and have a lovely rich potato flavor. This recipe will work with other types of potatoes too. 
  • Salt and pepper – potatoes love and need salt and pepper, use both generously and be sure to taste your potatoes before you serve. 
  • Butter – salted butter adds fat to this recipe, you need it to be the good base to the gratin. You can substitute with a vegan margarine for similar results. 
  • All-purpose flour – flour helps thicken the gratin sauce. Make sure you let it cook off in the butter for a few minutes to get less of a flour taste. 
  • Milk – milk adds a great texture to the sauce and is used to thin it. If you want a thinner sauce add more. 
  • Cheddar cheese – you want to use shredded cheese here to let it distribute evenly. 
  • Bacon – bacon has a super-rich intense salty flavor that compliments the potatoes and gives this potato side direction. 
  • Shallots – shallots have a flavor between onions and garlic so substitute with garlic and onion if you don’t have shallots. Slice them into thin half moons

When you have assembled the ingredients use the following method

Prep. Slice the potatoes with a sharp knife almost all the way through. Leave them connected at the bottom. Crisp the bacon in an oven safe pan and set aside.

Make Sauce. Pour the bacon grease out of the pan (pour it into a jar to save!). Melt the butter in the pan, add the shallots and cook 3-4 minutes. Mix in the flour, salt, and pepper and let cook for 1 minute. Whisk in the milk and cook until thickened. Stir in the cheese and melt about a minute.

Put it all together. Place the potatoes in the pan and coat in the sauce. Top with the cheese and bacon and cover with foil. Bake at 350 degrees for 45 minutes or until cheese is bubbling and potatoes are soft.

Finish in oven. Remove foil and bake 20-30 minutes or until cheese has browned and potatoes are crisp. Serve and enjoy!
