Ingredients You’ll Need

The magic in this Creamy Cheesy Au Gratin Potatoes Recipe comes from a blend of hearty Yukon gold potatoes, a luscious cheese sauce, and a perfectly golden cheesy crust. I always recommend choosing good quality cheese and fresh potatoes to make a real difference in the final dish.

• Yukon gold potatoes: Their creamy texture and thin skin make them perfect for thin slicing and baking without falling apart.
• White or yellow onion: Adds a mild sweetness and depth, balancing the richness of the cheese sauce.
• Salted butter: Essential for making the roux base of the sauce, adding a silky richness.
• All-purpose flour: Thickens the sauce—feel free to use whole wheat or gluten-free if needed.
• Milk (unsweetened almond or dairy): I usually use almond milk for a lighter feel, but whole milk gives even more creaminess.
• Sharp cheddar cheese: The heart of the cheesy flavor—you want a good sharp variety for that punch.
• Garlic powder: Adds subtle zing without overpowering.
• Salt and freshly ground black pepper: Always adjust seasonings to your taste; don’t be shy here.
• Gruyere cheese: For the topping, gives a nutty, melty golden crust.
• Parmesan cheese: Adds a salty, savory crisp topping that gets beautifully browned in the oven.
• Fresh parsley: For a fresh, vibrant garnish to brighten the dish.

Variations

I love how flexible this Creamy Cheesy Au Gratin Potatoes Recipe is. Over the years, I’ve played around with adding different flavors or switching up cheeses to tailor it to my mood or season. Don’t be afraid to get creative—you’ll enjoy how easy it is to make this recipe your own.

• Add Bacon or Ham: I once added 8 ounces of crispy cooked bacon folded into the potatoes before pouring the sauce—such a smoky, savory upgrade that my family devoured.
• Cheese Swaps: Gruyere is traditional for the topping, but experimenting with mozzarella, gouda, or even pepper jack adds a fun twist.
• Dairy-Free Version: Using almond milk and a plant-based cheese works surprisingly well if you’re dairy-free.
• Seasonal Veggies: Try layering thin slices of cooked cauliflower or mushrooms for an earthy depth.

How to Make Creamy Cheesy Au Gratin Potatoes Recipe

Step 1: Prepare the Potatoes and Onions Just Right

Start by preheating your oven to 375°F and greasing your baking dish—I’ve found a 2-quart square or an 8×12 inch dish works beautifully. Slice your Yukon gold potatoes into thin 1/8 inch rounds; thin enough to cook evenly, but not so thin they fall apart. Arrange the potato slices in three slanted rows in your dish, leaving a bit of space so they bake evenly. Add the onion slices in between and on top wherever you can fit them. This layering is key to building flavor throughout.

Step 2: Whip Up That Velvety Cheese Sauce

In a saucepan over medium heat, melt the butter, then whisk in a bit of flour to make the roux. Don’t rush here—whisk constantly to avoid lumps. Slowly alternate adding your milk and more flour, whisking vigorously, until the mixture is smooth and starts to thicken into a creamy gravy consistency. When it simmers, turn the heat down low, then add the shredded sharp cheddar, garlic powder, salt, and pepper. Give it a taste and adjust the seasoning as needed. This sauce is the magic glue that pulls everything together.

Step 3: Pour, Cover, and Bake

Pour the luscious cheese sauce over the potato and onion layers, covering them evenly. Don’t fret if it looks a bit thick now—the oven will work its magic making it irresistibly creamy. Cover the pan tightly with foil and bake for 45 minutes. This slow baking lets the potatoes soften perfectly without drying out.

Step 4: Cheese Topping Time

After 45 minutes, remove the foil and sprinkle the top with gruyere and parmesan cheese. Pop it back in the oven for another 30-45 minutes uncovered to get that glorious golden-brown crust. The key test? The potatoes are done when you can easily pierce the center with a fork. Once perfect, garnish with chopped fresh parsley for a pop of color and freshness.

How to Serve Creamy Cheesy Au Gratin Potatoes Recipe

Garnishes

I always finish off my au gratin potatoes with a sprinkle of fresh chopped parsley—it adds a hint of color and a fresh, herby note that balances all the richness. Sometimes, a few crispy bacon bits on top work wonders too if I’m feeling indulgent.

Side Dishes

This dish pairs beautifully with just about any main, but I especially love it alongside roast chicken, grilled steak, or a simple green salad to lighten things up. It’s always a hit on holiday tables or cozy family dinners.

Creative Ways to Present

One fun idea I’ve tried for special occasions is baking the potatoes in individual ramekins—this personal touch makes it feel extra fancy. You can also top with edible flowers or microgreens for a restaurant-quality wow factor!

Make Ahead and Storage

Storing Leftovers

I keep leftovers tightly covered in the original baking dish or divided into airtight containers in the fridge. They last for up to 5 days, making for incredibly easy reheating for quick meals during the week.

Freezing

I’ve frozen this recipe successfully by assembling it fully but baking it partially first, then cooling completely before freezing. When ready, thaw in the refrigerator overnight and finish baking as directed. It tastes just as creamy afterward, although the topping can lose a bit of its crispness.

Reheating

I find reheating in the oven at 350°F, covered with foil, for about 20 minutes does the trick to warm through without drying it out. For individual servings, a quick zap in the microwave also works great when you’re in a hurry.
