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.

Bake

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. Remove foil and bake 20-30 minutes till cheese is browned. Enjoy!

Tips and Tricks

Don’t skimp on the salt. Potatoes need lots of salt, so you don’t want to skimp on the salt. Make sure you taste the potatoes before serving too.

Make sure you cut the potatoes deep enough. You want to make sure you cut the potatoes as far as you can without cutting through. You want the sauce to be able to penetrate all the way through.

FAQs

Yes, for the right texture, you’ll partially bake potatoes before baking in the cheddar cream sauce.
