- 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)

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

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 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 is enough space between slices so they can cook evenly. Add onion slices in between and on top of the potato layers.
Step 3: Make the Sauce
In a medium saucepan over medium heat, melt the butter. Once melted, whisk in a little flour at a time while gradually adding almond milk. Continue whisking until you reach a creamy gravy-like consistency.
Step 4: Add Cheese and Seasoning
Lower the heat and stir in shredded cheddar cheese along with garlic powder, salt, and pepper. Taste before adjusting seasoning as necessary.
Step 5: Pour Sauce Over Potatoes
Evenly pour the sauce over the arranged potatoes and onions, ensuring they are well covered.
Step 6: Bake Covered
Cover your baking dish with foil and bake in preheated oven for 45 minutes.
Step 7: Add Toppings
After 45 minutes, remove the foil. Sprinkle shredded gruyere cheese (or more cheddar) and grated parmesan on top. Return to oven and bake uncovered for an additional 30-45 minutes until golden brown and fork-tender.

Common Mistakes to Avoid
