Ingredients You’ll Need
This recipe calls for straightforward, pantry-friendly ingredients that work harmoniously to create layers of flavor and texture. Each one plays a vital role, from the natural sweetness of Yukon gold potatoes to the melty sharp cheddar that forms the dish’s creamy foundation.
- 6-7 medium Yukon gold potatoes, thinly sliced: These potatoes hold their shape beautifully and offer a buttery flavor perfect for gratins.
- ½ white or yellow onion, sliced: Adds a subtle sweetness and depth that balances the rich cheese sauce.
- 2 tablespoons salted butter: Provides a smooth base for the roux and enriches the sauce.
- ¼ cup all-purpose flour: Thickens the milk into a velvety cheese sauce without lumps.
- 1 ½ cups unsweetened almond milk (or regular milk): Creates the creamy texture that binds everything together; almond milk keeps it light.
- 8 ounces sharp cheddar cheese, shredded: The star cheese that delivers a bold, tangy flavor.
- ½ teaspoon garlic powder: Brings a subtle savory note enhancing the umami.
- ¾ teaspoon salt: Essential for seasoning and drawing out flavors.
- Freshly ground black pepper: Adds a hint of spice and freshness.
- ½ cup gruyere cheese (optional): For an extra nutty, melty topping that crisps perfectly.
- ¼ cup grated parmesan: Boosts the gratin’s golden crust with a salty punch.
- Fresh parsley for garnish: Adds a welcoming pop of color and mild freshness at the end.
How to Make Dad’s Creamy & Cheesy Au Gratin Potatoes Recipe
Step 1: Prepare Your Oven and Dish
Begin by preheating your oven to 375°F. Grease a 2-quart square baking dish thoroughly; this little step ensures the potatoes won’t stick and the crust will brown evenly. It’s the foundation for a beautiful bake.
Step 2: Layer Potatoes and Onions
Arrange the thinly sliced Yukon gold potatoes and onions in alternating layers across the baking dish. This layering technique helps distribute flavors and textures perfectly through every bite, with tender potatoes softened by the sweet, fragrant onions.
Step 3: Create the Cheese Sauce
Over medium heat, melt the salted butter in a saucepan. Whisk in the all-purpose flour to create a smooth roux, cooking it for a minute or two to get rid of any raw flour taste. Slowly add your milk while whisking constantly to avoid lumps, cooking until the sauce thickens to a silky consistency that will coat the potatoes just right.
Step 4: Add Cheese and Seasoning
Reduce the heat and stir in the shredded sharp cheddar cheese, garlic powder, salt, and freshly ground black pepper. Keep stirring until the cheese melts completely and the sauce becomes gorgeously creamy and flavorful. This step is where the magic really happens—your kitchen will smell incredible!
Step 5: Pour Sauce and Bake Covered
Pour the luscious cheese sauce evenly over the layered potatoes and onions, making sure every slice is bathed in creamy goodness. Cover the dish with foil and bake for 45 minutes. This slow baking lets the potatoes soften properly without drying out.
Step 6: Add Toppings and Finish Baking
After the initial baking, remove the foil and sprinkle the optional gruyere and grated parmesan cheeses on top. Return the dish to the oven and bake uncovered for an additional 30 to 45 minutes. This final step creates a golden, bubbling crust with those irresistible crispy edges you crave.
Step 7: Garnish and Serve
Once out of the oven, let the gratin rest for a few minutes, then sprinkle with fresh parsley. The vibrant green garnish adds a fresh contrast to the rich, creamy potatoes and completes this classic dish beautifully.

Storing Leftovers
If you have leftovers, store them in an airtight container in the refrigerator. They will keep beautifully for 3 to 4 days while maintaining their creamy texture and cheesy flavor, making for convenient and delicious next-day meals.
Freezing
This recipe freezes well if you want to keep it longer. After baking and cooling completely, cover the dish tightly with plastic wrap and foil before freezing. It can be stored for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating
Reheat leftover gratin in the oven at 350°F until warmed through to preserve that crispy top and creamy interior. You can cover it loosely with foil to avoid over-browning, removing the foil near the end to revive the golden finish.
FAQs
Can I use different types of potatoes for this recipe?
While Yukon gold potatoes are ideal for their creamy texture and buttery flavor, you can use Russet potatoes in a pinch. Just keep in mind that Russets are starchier and may result in a slightly different texture.
Is it necessary to use almond milk or can I substitute something else?
You can absolutely substitute regular whole milk or even half-and-half if you prefer a richer sauce. Almond milk works well for a lighter version or if you’re dairy sensitive.
Can I prepare this dish entirely ahead of time and bake later?
Yes! You can assemble the gratin fully and keep it covered in the fridge for up to 24 hours before baking. This makes it perfect for busy weeknights or holiday meals.
What can I add to make the gratin more flavorful?
Adding fresh herbs like thyme or rosemary to the cheese sauce, or incorporating caramelized onions in place of raw onions, can introduce deeper flavors that complement Dad’s Creamy & Cheesy Au Gratin Potatoes Recipe beautifully.
How can I make the top crispier?
For an extra crispy top, sprinkle some breadcrumbs mixed with melted butter on the cheese layer before the final bake. This will create a wonderful crunchy contrast to the creamy potatoes beneath.

Ingredients
Potatoes and Vegetables
- 6–7 medium Yukon gold potatoes, thinly sliced
- ½ white or yellow onion, sliced
Sauce
- 2 tablespoons salted butter
- ¼ cup all-purpose flour
- 1 ½ cups unsweetened almond milk (or regular milk)
- 8 ounces sharp cheddar cheese, shredded
- ½ teaspoon garlic powder
- ¾ teaspoon salt
- Freshly ground black pepper, to taste
Toppings and Garnish
- ½ cup gruyere cheese (optional)
- ¼ cup grated parmesan cheese
- Fresh parsley for garnish
Instructions
- Preheat and Prepare the Baking Dish: Preheat your oven to 375°F (190°C). Grease a 2-quart square baking dish generously to prevent sticking.
- Layer Potatoes and Onions: Arrange the thinly sliced Yukon gold potatoes and sliced onions alternatingly in the prepared baking dish, creating even layers for uniform cooking.
- Make the Cheese Sauce: In a medium saucepan over medium heat, melt the salted butter. Whisk in the all-purpose flour until it forms a smooth paste, cooking for about 1-2 minutes to eliminate raw flour taste. Gradually whisk in the almond milk or regular milk, stirring constantly until the sauce thickens and is smooth.
- Add Cheese and Seasonings: Stir in the shredded sharp cheddar cheese, garlic powder, salt, and freshly ground black pepper until the cheese melts completely and the sauce is creamy and well combined.
- Combine Sauce with Potatoes: Pour the prepared cheese sauce evenly over the layered potatoes and onions in the baking dish, ensuring the sauce covers all layers.
- Bake Covered: Cover the baking dish tightly with aluminum foil and bake in the preheated oven for 45 minutes. This will help the potatoes cook through and the flavors meld.
- Add Toppings and Finish Baking: Remove the foil and sprinkle the grated gruyere cheese and parmesan cheese evenly over the top. Return the dish to the oven and bake for an additional 30 to 45 minutes, or until the cheese topping is golden brown and bubbly, and the potatoes are tender when pierced with a fork.
- Garnish and Serve: Once baked, remove from the oven and let it rest for a few minutes. Garnish with freshly chopped parsley before serving warm as a hearty side dish.
Notes
- For a richer flavor, use regular whole milk instead of almond milk.
- Gruyere cheese is optional but adds a lovely nuttiness; you can substitute with more cheddar if unavailable.
- Use a mandoline slicer for uniformly thin potato slices to ensure even cooking.
- Make sure to cover the dish while baking to prevent the cheese topping from burning before the potatoes are cooked through.
- This dish can be prepared a day ahead and refrigerated; add extra baking time if baking from cold.
- Adjust salt according to the saltiness of the cheeses used.
