Ingredients You’ll Need
Simple ingredients come together beautifully in this recipe, each playing a key role in building layers of flavor, creaminess, and texture. From the buttery richness of the sauce to the mellow sweetness of the onions, every element is essential to make these potatoes shine.
- 6-7 medium Yukon gold potatoes: Their creamy texture and subtle sweetness hold up wonderfully when sliced thin and baked.

- ¼ cup all-purpose flour: Key to thickening the cheese sauce into that perfect creamy consistency.

- 8 ounces sharp cheddar cheese, shredded: The star cheese that brings bold, melty cheesiness to every layer.
- ½ teaspoon garlic powder: A subtle kick that deepens the savory profile.
- ¾ teaspoon salt: Balances and elevates all the flavors in the dish.
- Freshly ground black pepper: Adds just enough heat and complexity.

How to Make Dad’s Creamy & Cheesy Au Gratin Potatoes Recipe
Step 1: Preheat and Prepare Your Dish
Start by heating your oven to 375°F and greasing a 2-quart square baking dish. This simple step ensures your potatoes don’t stick and helps give those beautiful crispy edges once baked.
Step 2: Layer the Potatoes and Onions
Slice your Yukon gold potatoes and onions thinly—uniform slices help everything cook evenly. Arrange them in the baking dish in layers, letting the potatoes nestle up against the onions for a lovely blend of textures and flavors.
Step 3: Make the Creamy Cheese Sauce
On medium heat, melt your butter in a saucepan. Whisk in the flour carefully to create a roux, cooking it until it’s smooth and just starting to bubble. Gradually add the almond milk, whisking constantly to avoid lumps, until your sauce thickens into a luscious, creamy blanket for the potatoes.
Step 4: Add the Cheeses and Seasonings
Once thickened, stir in the shredded cheddar, garlic powder, salt, and pepper. This is where the sauce turns irresistibly cheesy and flavorful. The gooey cheddar creates the signature richness of Dad’s Creamy & Cheesy Au Gratin Potatoes Recipe, while the seasonings make every bite sing.
Step 5: Pour the Sauce and Bake Covered
Pour the warm cheese sauce evenly over the layered potatoes and onions. Cover the dish tightly with foil, then bake for 45 minutes. This steam-infused bake allows the potatoes to soften beautifully in the rich, cheesy sauce.
Step 6: Add the Final Cheese Topping and Finish Baking
Remove the foil and sprinkle the gruyere and parmesan cheeses over the top. Return the dish to the oven for another 30-45 minutes, until the top is golden, bubbly, and slightly crisp—a perfect contrast to the creamy layers beneath.
Step 7: Garnish and Serve
Once out of the oven, a sprinkle of fresh parsley adds a vibrant touch and a hint of herbaceous freshness that balances the richness. Your Dad’s Creamy & Cheesy Au Gratin Potatoes Recipe is now ready to impress!

Garnishes
Fresh chopped parsley is a simple but effective garnish that adds brightness and color to this indulgent dish. You could also try a sprinkle of crispy fried onions for added crunch and a burst of flavor on top.
Side Dishes
This gratin pairs wonderfully with roasted meats like chicken or beef, steamed green beans, or a crisp green salad. Its creamy texture and cheesy flavors make it a perfect hearty side that complements lighter, fresher dishes beautifully.
Creative Ways to Present
For a fun twist, try making individual gratin portions in ramekins—great for dinner parties or holiday meals. Top each with a little extra cheese and fresh herbs before serving to make each plate feel special.
Make Ahead and Storage
Storing Leftovers
Store any leftover Dad’s Creamy & Cheesy Au Gratin Potatoes Recipe in an airtight container in the fridge for up to 3 days. It tastes fantastic warmed up, with all the creamy goodness still intact.
Freezing
You can freeze this dish, but it’s best to do so before the final cheese topping is added. Freeze in a suitable container and thaw overnight in the fridge before finishing the bake for best texture and flavor.
Reheating
Reheat leftovers gently in the oven at 350°F until warmed through to maintain the lovely creamy texture without drying out. Microwaving works in a pinch but beware of losing some of that crisp top.
FAQs
Can I use a different type of potato?
Yukon golds are ideal for their creamy texture, but you can use russet potatoes if that’s what you have on hand. Just be mindful that russets may result in a slightly drier texture, so adjust the sauce accordingly.
Is it possible to make this gluten-free?
Yes! Substitute the all-purpose flour with a gluten-free flour blend or cornstarch to thicken the sauce. Just whisk it in as you would the flour, and keep an eye on the thickness.
Can I use regular milk instead of almond milk?
Absolutely. Regular dairy milk works perfectly and may even make the sauce a bit richer. Almond milk is just a lighter alternative for those avoiding dairy.
What cheeses work best in this recipe?
Sharp cheddar is a must for that classic cheesy flavor, but gruyere and parmesan on top create a gorgeous nutty crust. You can experiment with fontina or mozzarella if desired, but the original combination is a crowd-pleaser.
How thin should I slice the potatoes?
Try to slice them about 1/8 inch thick to ensure they cook evenly and soak up all that cheese sauce. Using a mandoline slicer makes this step quick and consistent.
