Ingredients
For the Potatoes
- 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)

- ¾ teaspoon salt, plus more to taste
- Freshly ground black pepper
For Topping

How to Make Dad’s Creamy & Cheesy Au Gratin Potatoes
Step 1: Preheat the Oven
Preheat your oven to 375 degrees F. Spray a 2-quart square baking dish (or an 8×12 dish) with nonstick cooking spray or grease it with butter or oil.
Step 2: Arrange the Potatoes
Place sliced potatoes in three tight slanted rows in the prepared baking dish. Leave enough space between each slice so they can cook evenly. Add onion slices in between the potato rows and on top wherever possible.
Step 3: Prepare the Sauce
In a saucepan over medium heat, add 2 tablespoons of butter. Once melted, whisk in a little bit of the flour. Gradually add in the almond milk while continuing to whisk vigorously to prevent lumps from forming. Bring this mixture to a simmer until it thickens slightly.
Step 4: Add Cheese and Seasoning
Reduce heat to low. Stir in shredded cheddar cheese along with garlic powder, salt, and black pepper. Taste your sauce and adjust seasoning as needed.
Step 5: Pour Sauce Over Potatoes
Pour the prepared cheese sauce evenly over the arranged potatoes and onions in the baking dish. Don’t worry; it will become creamy during 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 shredded gruyere cheese (or additional cheddar) and grated parmesan. Return it to the oven for another 30-45 minutes until golden brown on top. The potatoes are done when you can easily pierce them with a fork. Finally, garnish with fresh chopped parsley before serving!

Common Mistakes to Avoid
When making Dad’s Creamy & Cheesy Au Gratin Potatoes, it’s easy to make a few common mistakes. Here are some tips to ensure your dish turns out perfectly every time.

- Skipping the seasoning: Seasoning is crucial for flavor. Always taste your sauce and adjust the salt and pepper before pouring it over the potatoes.
- Using too much flour: Adding too much flour can lead to a thick, gummy sauce. Start with less and add more if needed while whisking.
- Covering too tightly: Covering the dish too tightly with foil can trap steam, making the potatoes soggy. Leave a little space for steam to escape.
- Not letting it rest after baking: Allowing the dish to rest for a few minutes after baking helps set the sauce and makes serving easier.
