Ingredients You’ll Need
Don’t let this recipe’s incredible flavor fool you—the ingredients are wonderfully simple but each plays a crucial role. From the creamy potatoes to the sharp and nutty cheeses, every element adds a unique touch to the final dish.
- 6-7 medium Yukon gold potatoes, thinly sliced: These are perfect for their creamy texture and ability to hold shape without falling apart.
- ½ white or yellow onion, sliced: Adds a subtle savory sweetness that balances the richness.
- 2 tablespoons salted butter: Essential for building that silky, flavorful cheese sauce.
- ¼ cup all-purpose flour: Acts as the thickening agent for the velvety sauce.
- 1 ½ cups unsweetened almond milk (or regular milk): Keeps the sauce creamy without overpowering the cheese.
- 8 ounces sharp cheddar cheese, shredded: The star of the show for that classic cheesy punch.
- ½ teaspoon garlic powder: Adds subtle depth and warmth.
- ¾ teaspoon salt: Enhances all the flavors beautifully.
- Freshly ground black pepper: A touch of pepper brings brightness and a little kick.
- ½ cup gruyere cheese (optional): Adds a nutty, melting creaminess that elevates the dish.
- ¼ cup grated parmesan: Creates a golden, savory crust with every bite.
- Fresh parsley for garnish: A fresh, colorful finish to balance all that richness.
How to Make Dad’s Creamy & Cheesy Au Gratin Potatoes Recipe
Step 1: Prepare Your Oven and Dish
Start by preheating your oven to 375°F and greasing a 2-quart square baking dish. This sets the stage for your au gratin to bake evenly and prevents sticking, ensuring an easy, clean removal and serving experience.
Step 2: Layer the Potatoes and Onions
Arrange thin slices of Yukon gold potatoes in the dish, alternating with thinly sliced onions. This layering creates a beautiful texture contrast and ensures every forkful has a balance of tender potatoes and sweet onion.
Step 3: Make the Cheese Sauce
In a saucepan over medium heat, melt the salted butter and whisk in the flour. Slowly add the almond milk (or regular milk), whisking continuously until the mixture thickens to a creamy consistency. This roux-based sauce will coat your potatoes beautifully.
Step 4: Add Cheese and Seasonings to the Sauce
Stir sharp cheddar cheese, garlic powder, salt, and freshly ground black pepper into the sauce. The sharp cheddar melts perfectly to give that signature creaminess packed with flavor; garlic powder and seasoning add a subtle but necessary punch.
Step 5: Combine Sauce with Potatoes and Onions
Pour the luscious cheese sauce evenly over the layered potatoes and onions. Make sure everything is generously coated so each bite melts in your mouth with cheesy goodness.
Step 6: Bake Covered, Then Uncover and Top
Cover the baking dish with foil and bake for 45 minutes. This allows the potatoes to become tender while trapping moisture for the sauce. Afterward, remove the foil and sprinkle the top with gruyere and parmesan cheeses. Return to the oven uncovered and bake for an additional 30-45 minutes until that top turns irresistibly golden brown and bubbly.
Step 7: Finish with Fresh Parsley
Once out of the oven, garnish your au gratin with fresh parsley for a burst of color and a hint of herbal brightness that cuts through the richness perfectly.

Garnishes
A sprinkle of freshly chopped parsley is not only visually appealing but adds a fresh flavor contrast to the decadence of the cheese. For an extra touch, a tiny dusting of smoked paprika can add a warm color and mild smoky note.
Side Dishes
This creamy au gratin works wonders alongside roasted meats like chicken, pork, or beef, acting as the ultimate comfort-food companion. Pair with a crisp green salad or steamed green beans to brighten the meal and add a fresh crunch.
Creative Ways to Present
If you’re serving at a special gathering, consider baking individual ramekins for elegant personal portions. Alternatively, top with crispy fried onions or breadcrumbs for a crunchy twist that adds another layer of texture to this classic dish.
Make Ahead and Storage
Storing Leftovers
After cooking, allow your au gratin potatoes to cool completely before transferring to an airtight container. They will keep beautifully in the refrigerator for 3-4 days, making them an ideal make-ahead side dish for busy weeknights.
Freezing
Dad’s Creamy & Cheesy Au Gratin Potatoes Recipe freezes well if you want to save some for later. Freeze portions in freezer-safe containers for up to 2 months. When ready to enjoy, thaw overnight in the fridge before reheating.
Reheating
Reheat leftovers in a preheated oven at 350°F until warmed through to keep that creamy, melty goodness intact. Microwaving is quicker but may sacrifice some of the delightful texture of the crispy cheese topping.
FAQs
Can I use a different type of potato?
While Yukon gold potatoes are recommended for their creamy texture, you can use russets or red potatoes. Just keep in mind that the texture and cook time may vary slightly.
Is it okay to use regular milk instead of almond milk?
Absolutely! Regular milk works just as well and adds a traditional creamy richness, but almond milk is a great dairy-free alternative that keeps the sauce smooth.
Can I make this recipe vegetarian?
Yes, this dish is naturally vegetarian unless you add any meat-based toppings. Using vegetable-based broth or just the milk and cheese keeps it perfectly meat-free.
How thick should I slice the potatoes?
Slice your potatoes thinly—about 1/8 inch thick—to ensure they cook evenly and absorb that incredible cheese sauce flavor all the way through.
Can I prepare this recipe ahead of time and bake later?
Definitely. Assemble your potatoes and sauce in the dish, cover tightly with foil, and refrigerate up to 24 hours before baking. This makes it perfect for planning ahead for a busy day.

- ¼ cup grated parmesan
Dry and Seasonings
- ¼ cup all-purpose flour
- ½ teaspoon garlic powder
- ¾ teaspoon salt
- Freshly ground black pepper, to taste
Garnish
- Fresh parsley for garnish
Instructions
- Preheat Oven and Prepare Dish: Preheat your oven to 375°F (190°C) and lightly grease a 2-quart square baking dish with butter or non-stick spray to prevent sticking.
- Layer Potatoes and Onions: Arrange the thinly sliced Yukon gold potatoes and sliced onions in even layers within the prepared baking dish to ensure even cooking and flavor distribution.
- Make the Cheese Sauce: In a medium saucepan, melt the 2 tablespoons of salted butter over medium heat. Whisk in the ¼ cup of all-purpose flour until smooth to create a roux. Gradually pour in 1 ½ cups of unsweetened almond milk (or regular milk), whisking continuously until the mixture thickens into a smooth sauce.

- Combine Sauce with Potatoes: Pour the creamy cheese sauce evenly over the layered potatoes and onions, ensuring every slice is coated for a rich flavor.
- Bake Covered: Cover the baking dish tightly with aluminum foil and bake in the preheated oven for 45 minutes. This allows the potatoes to soften and begin cooking through.

- Garnish and Serve: Once baked to perfection, remove from the oven and garnish with freshly chopped parsley for a burst of color and freshness. Serve warm as a delicious side dish.
Notes
- Use Yukon gold potatoes for their creamy texture and buttery flavor, but russet potatoes can also be used if preferred.
- If you do not have gruyere cheese, you can substitute with more cheddar or mozzarella for a different cheese profile.
- For a thicker sauce, reduce the milk slightly or cook the sauce a bit longer until desired consistency is reached.
- This dish can be prepared a day ahead; refrigerate after layering and assembling, then bake when ready.
- Using almond milk makes this dish lactose-free; regular milk can be used for a richer taste.
