For the au gratin:

67 medium Yukon Gold potatoes, thinly sliced into 1/8th inch rounds (about 3 pounds)

1/2 white or yellow onion, thinly sliced

For the sauce:

2 tbsp. salted butter

1/4 cup all-purpose flour (whole wheat, all-purpose, or gluten-free 1:1 flour can be used)

1 1/2 cups unsweetened almond milk (or your choice of milk)

8 ounces sharp cheddar cheese (approximately 2 heaping cups shredded)

1/2 tsp garlic powder

3/4 tsp salt, plus more to taste

Freshly ground black pepper

For topping:

1/2 cup gruyere cheese (or more sharp cheddar)

1/4 cup grated parmesan

To garnish:

Fresh chopped parsley


Preheat the oven to 375°F (190°C). Make sure to grease a 2 baking dish.

Arrange the sliced potatoes and onions, in layers within the dish.

In a saucepan melt some butter over medium heat. Then whisk in flour, gradually adding milk while whisking to prevent any lumps from forming. Let it simmer until it thickens nicely.

Now add cheddar cheese, garlic powder, salt and pepper to the sauce. Taste it. Adjust the seasoning according to your preference.

Next, pour this cheese sauce over the layered potatoes and onions in the baking dish.

Cover the dish with foil. Bake it for 45 minutes.

After that time has passed, remove the foil from the dish. Sprinkle some gruyere and parmesan on top of everything and continue baking for 30 to 45 minutes until you achieve a golden brown color.

Finally, once you take it out of the oven garnish with parsley, for an added touch of freshness. Now you can sit back. Enjoy this dish!


To create a gluten-free rendition of Creamy & Cheesy Au Gratin Potatoes you just need to switch out the all-purpose flour with a gluten-free flour blend. Just make certain that the flour blend you choose is particularly pointed for substituting one to one, with all-purpose flour so that the consistency remains the same.

In addition, it’s crucial to guarantee that all other elements, including the cheese and any seasoning blends, are authenticated gluten-free. By making these changes you can still relish the creamy and cheesy deliciousness while tracking a gluten-free diet.
