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)

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 prepared baking dish. Ensure they are not overly tight; leave enough space so potato slices are slightly slanted. Add onion slices in between the rows and on top of the potatoes wherever you can fit them.
Step 3: Make the Cheese Sauce
In a saucepan over medium heat, melt 2 tablespoons of butter. Once melted, whisk in a little bit of flour at a time while slowly adding milk. Alternate between adding flour and milk while whisking vigorously to prevent lumps. Bring the mixture to a simmer until it reaches a consistency similar to creamy gravy.
Step 4: Add Cheese and Seasonings
Lower the heat and stir in shredded cheddar cheese along with garlic powder, salt, and pepper. Taste the sauce and adjust seasonings if necessary.
Step 5: Pour Sauce Over Potatoes
Evenly pour the cheese sauce over the arranged potatoes and onions to cover everything well. Don’t worry; it will get nice and 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, remove the foil. Sprinkle the top of the potatoes with ½ cup shredded gruyere (or additional cheddar) and ¼ cup parmesan. Return to the oven for another 30-45 minutes or until potatoes are tender and golden brown on top. You can check doneness by piercing the middle of the potatoes with a fork. Garnish with fresh chopped parsley before serving. Enjoy!

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.
- Overcrowding the Potatoes – Placing the potato slices too tightly can lead to uneven cooking. Make sure there is enough space between the slices for the sauce to soak in.
- Using the Wrong Cheese – Not all cheeses melt well. Stick to sharp cheddar and gruyere for that creamy texture and flavor. Avoid using pre-shredded cheese, as it often contains anti-caking agents.
- Skipping the Onion – The onion adds flavor and depth. Don’t skip this ingredient; it enhances the overall taste of your au gratin potatoes.
- Not Tasting the Sauce – Failing to taste your cheese sauce before pouring it over the potatoes can result in blandness. Adjust seasoning as needed with salt and pepper.
- Removing Foil Too Early – Taking off the foil too soon can cause the dish to dry out. Keep it covered for most of the baking time to lock in moisture.
Refrigerator Storage
- Store leftovers in an airtight container.
- Consume within 3-5 days for best quality.

- Place in a freezer-safe container or wrap tightly with plastic wrap and aluminum foil.
- Use within 2-3 months for optimal flavor.
