Ingredients
Ingredients:
– 6-7 medium yukon gold potatoes, thinly sliced into 1/8th inch rounds (3 pounds gold potatoes — by weight is a more accurate measure)
– ½ white or yellow onion, cut into slices
– For the sauce:
– 2 tablespoons salted butter
– ¼ cup all purpose flour (whole wheat, all purpose, or gluten free 1:1 flour will all work)
– 1 ½ cups unsweetened almond milk (regular, skim or whole milk will also work)
– 8 ounces sharp cheddar cheese (2 heaping cups shredded cheddar cheese)
– ½ teaspoon garlic powder
– ¾ teaspoon salt, plus more to taste
– Freshly ground black pepper
– For topping:
– ½ cup gruyere cheese (or sub more sharp cheddar)
– ¼ cup grated parmesan
– To garnish:
– Fresh chopped parsley
How to Make Dad’s Creamy & Cheesy Au Gratin Potatoes
Step 1: Preheat the Oven
Preheat the oven to 375 degrees F. Spray your baking dish with nonstick cooking spray or grease it with butter or oil.
Step 2: Arrange the Potatoes and Onions
Place sliced potatoes in three slanted rows within the baking dish. Ensure there is enough space between slices for even cooking. Add onion slices between rows and on top where possible.
Step 3: Make the Cheese Sauce
In a medium saucepan over medium heat, melt 2 tablespoons of butter. Gradually whisk in some flour, then slowly add milk while whisking continuously until smooth. Bring the mixture to a simmer until it thickens like creamy gravy.
Step 4: Combine Cheese with Sauce
Reduce heat to low and stir in shredded cheddar cheese along with garlic powder, salt, and pepper. Taste and adjust seasoning as needed.
Step 5: Pour Sauce Over Potatoes
Evenly pour the cheesy sauce over the arranged potatoes and onions. The sauce will thicken further while baking.
Step 6: Bake Covered
Cover your baking dish with foil and bake for 45 minutes.
Step 7: Add Toppings and Finish Baking
After 45 minutes, remove the foil. Sprinkle the top with gruyere cheese (or additional cheddar) and parmesan. Return to the oven for another 30–45 minutes until golden brown on top and easily pierced with a fork.
Remove from oven, garnish with fresh chopped parsley, serve hot, and enjoy!

- Ignoring seasoning: Failing to taste and adjust seasoning may lead to bland potatoes. Don’t forget to add salt and pepper gradually for the best flavor.
- Not covering while baking: Skipping the foil cover during the initial bake can dry out the potatoes. Keep them moist by covering your dish until it’s time to add the cheese topping.
- Rushing the cooling time: Cutting into the dish immediately after baking can make it fall apart. Letting it rest allows flavors to meld and makes serving easier.
