- 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)

For Topping

How to Make Dad’s Creamy & Cheesy Au Gratin Potatoes
Step 1: Preheat the Oven
Preheat the oven to 375 degrees F. Spray a 2-quart square baking dish (or an 8×12) with nonstick cooking spray or grease it with butter or oil.
Step 2: Arrange the Potatoes and Onions
Place sliced potatoes in three tight slanted rows in the baking dish. Ensure there’s enough space so that potato slices are slightly slanted. Add onion slices between the rows and on top of the potatoes.
Step 3: Make the Sauce
In a medium saucepan over medium heat:
1. Add 2 tablespoons of butter until melted.
2. Whisk in a little bit of flour at a time.
3. Slowly add milk while continuously whisking to prevent lumps.
4. Bring mixture to a simmer; it should have a creamy gravy-like consistency.
Step 4: Add Cheese and Seasoning
Lower the heat, then stir in shredded cheddar cheese, garlic powder, salt, and pepper. Taste and adjust seasoning if needed.
Step 5: Pour Sauce Over Potatoes
Pour the sauce evenly over the arranged potatoes and onions. Don’t worry; it’ll become creamy while baking.
Step 6: Bake Covered
Cover the pan with foil and bake for 45 minutes.
Step 7: Add Toppings and Finish Baking
After 45 minutes:
1. Remove foil.
2. Sprinkle top with ½ cup shredded gruyere (or more cheddar) and ¼ cup parmesan.
3. Return to oven; bake uncovered for an additional 30-45 minutes until golden brown on top and easily pierced with a fork.
Remove from oven, garnish with fresh chopped parsley, and enjoy!

Common Mistakes to Avoid
When making Dad’s Creamy & Cheesy Au Gratin Potatoes, it’s easy to overlook some key steps. Here are common mistakes to watch out for.
- Using uneven potato slices: For even cooking, make sure all potato slices are the same thickness. This ensures that they bake evenly and become tender at the same time.
- Skipping the seasoning: Don’t forget to season your sauce! A lack of salt and pepper can lead to bland potatoes. Always taste your sauce before pouring it over the potatoes.
- Not covering while baking: If you skip covering the dish with foil initially, the top may brown too quickly while the potatoes remain undercooked. Covering helps retain moisture and allows for proper cooking.
- Overcrowding the dish: Placing too many potato slices too closely can prevent them from cooking through. Ensure there is enough space between slices for heat circulation.
- Ignoring resting time: Allowing your au gratin potatoes to rest after baking helps them set up properly. Cutting too soon can result in a soupy texture.
