Ingredients You’ll Need
This recipe shines because of how simple yet essential each ingredient is. Every element works together to build layers of flavor, creaminess, and texture that make the dish irresistible.
- 6-7 medium Yukon gold potatoes: Their waxy texture holds up well while baking, giving you tender but not mushy slices.
- ½ white or yellow onion: Adds a subtle sweetness and a bit of crunch between the potato layers.
- 2 tablespoons salted butter: The base of the luscious cheese sauce for richness and flavor.
- ¼ cup all-purpose flour: Used to thicken the sauce into a smooth, creamy consistency.
- 1 ½ cups unsweetened almond milk (or regular milk): Provides the silky liquid foundation for the sauce; almond milk keeps it dairy-light if preferred.
- 8 ounces sharp cheddar cheese, shredded: Infuses the dish with bold, melty cheesiness that’s truly the heart of the recipe.
- ½ teaspoon garlic powder: Brings a warm, savory undertone without overpowering the dish.
- ¾ teaspoon salt: Highlights and balances all the flavors perfectly.
- Freshly ground black pepper: Adds a gentle kick and depth to each bite.
- ½ cup gruyere cheese (optional): A wonderful addition for a nutty, creamy top layer that browns beautifully.
- ¼ cup grated parmesan: Creates a crispy, umami-packed crust on top.
- Fresh parsley for garnish: Adds a pop of color and a fresh brightness to cut through the richness.
How to Make Dad’s Creamy & Cheesy Au Gratin Potatoes Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 375°F and greasing a 2-quart square baking dish. This sets the stage for a beautifully baked dish without anything sticking, ensuring those creamy cheese layers can shine in every slice.
Step 2: Layer the Potatoes and Onions
Thinly slice your Yukon gold potatoes and the onion, then arrange them in layers inside the greased dish. This layering is what gives the au gratin its perfect texture contrast between the tender potatoes and the slightly sweet onion slices.
Step 3: Make the Cheese Sauce
In a medium saucepan, melt salted butter over medium heat. Whisk in the flour to create a smooth roux, then gradually add your milk of choice, whisking constantly until the mixture thickens into a rich, creamy sauce. This step is key because the sauce is what envelops every potato slice in that iconic creamy, cheesy goodness.
Step 4: Add Cheese and Seasonings
Stir in shredded sharp cheddar cheese, garlic powder, salt, and freshly ground black pepper into the sauce. Allow the cheese to melt completely for that perfect velvety texture packed with bold flavor.
Step 5: Pour Sauce and Bake Covered
Pour the hot cheese sauce evenly over the layered potatoes and onions, making sure every slice gets that luxurious coating. Cover the dish with foil to trap the steam and bake for 45 minutes. This initial bake softens the potatoes and melds the flavors wonderfully.
Step 6: Add the Finishing Cheeses and Bake Uncovered
Remove the foil, then sprinkle gruyere cheese and parmesan over the top for an irresistible golden crust. Return the dish to the oven and bake uncovered for another 30 to 45 minutes until bubbly and beautifully browned. This final step creates the signature cheesy crust that makes this recipe unforgettable.
Step 7: Garnish and Serve
Once out of the oven, sprinkle fresh parsley over the top. This adds a fresh color contrast and a hint of herbal brightness that compliments the rich flavors perfectly.

Side Dishes
This irresistible side pairs perfectly with roasted meats like chicken, beef, or pork. It’s also divine alongside a fresh green salad or steamed vegetables to balance out the indulgence. Its creamy texture and deep flavors make it a natural companion to any main course that calls for a comforting side.
Creative Ways to Present
For a fun twist at your next dinner party, serve Dad’s Creamy & Cheesy Au Gratin Potatoes Recipe in individual ramekins or mini cast iron skillets. You can also add layers of cooked bacon or caramelized onions for smoky, sweet notes that surprise and delight.
Make Ahead and Storage
Storing Leftovers
Simply cover the dish tightly with plastic wrap or transfer leftovers to an airtight container and refrigerate for up to 3-4 days. The flavors actually deepen, making it just as delicious the next day.
Freezing
You can freeze this au gratin dish for up to 2 months. Freeze before baking by covering tightly with foil and plastic wrap to prevent freezer burn. When ready to enjoy, thaw overnight in the refrigerator for best results.
Reheating
Reheat leftovers in the oven at 350°F for about 20-25 minutes, covered with foil to retain moisture. Remove foil in the last 5-10 minutes to refresh the golden top. Microwaving is possible too, but you might lose some of that lovely crust.
FAQs
Can I use a different type of potato?
Absolutely! Yukon gold potatoes are preferred for their creamy texture and ability to hold shape, but russets or red potatoes can also work. Just keep in mind that starchier potatoes may become a bit softer after baking.
Is there a dairy-free version of this recipe?
Yes! Using unsweetened almond milk instead of regular milk helps, and you can substitute dairy-free butter and vegan cheese alternatives to keep the dish creamy without any dairy.
What if I don’t have gruyere or parmesan?
No worries! You can simply use extra sharp cheddar for the topping or try mozzarella or a mild Swiss cheese to keep the flavor balanced and the crust golden.
Can I prepare this recipe a day ahead?
Definitely. Prepare and assemble the dish up to the point of baking, then cover and refrigerate overnight. When you’re ready, bake as directed. This makes it perfect for busy days or holiday meals.
How thick should the potato slices be?
Thin slices about 1/8 inch thick work best — this helps the potatoes cook evenly and absorb the creamy sauce fully. A mandoline slicer is a great tool for consistent thickness and faster prep.
