How to Make Dad’s Creamy & Cheesy Au Gratin Potatoes
Step 1: Preheat the Oven
Start by preheating your oven to 375 degrees F. This ensures that your au gratin potatoes will bake evenly from the moment they go in. Grease a baking dish with nonstick spray or butter to prevent sticking.
Step 2: Layer Your Potatoes
Arrange your sliced potatoes in three tight slanted rows within the baking dish. Make sure they’re slightly slanted—not too tight! This allows heat to circulate, cooking them evenly. Sprinkle onion slices among the potatoes wherever there’s room; they add wonderful flavor as they cook.
Step 3: Make Your Sauce
In a saucepan over medium heat, melt your butter. Once it’s melted, whisk in some flour slowly while adding the almond milk gradually. Keep whisking until there are no lumps and the mixture is smooth like creamy gravy. This step is crucial because it creates that dreamy sauce we all love!
Step 4: Add Cheese and Seasoning
Now it’s time to bring on the flavor! Lower the heat and stir in your shredded cheddar cheese along with garlic powder, salt, and freshly ground black pepper. Taste as you go—adjusting seasoning ensures every bite is delicious.
Step 5: Pour Sauce Over Potatoes
Pour your creamy sauce evenly over those beautiful layers of potatoes and onions. Don’t worry if things look a bit messy now; as they bake, everything will come together beautifully.
Step 6: Bake Covered
Cover your baking dish with foil and pop it in the oven for about 45 minutes. This helps steam the potatoes until they’re tender without burning them.
Step 7: Add Toppings and Finish Baking
After those first 45 minutes are up, remove the foil and sprinkle gruyere and parmesan on top. Return it to the oven uncovered for another 30-45 minutes until everything is bubbling hot and golden brown on top. You’ll know it’s done when you can easily pierce through to the center of those potatoes.
Finally, take your masterpiece out of the oven! Garnish with fresh chopped parsley before serving—this little touch adds color and freshness! Enjoy every cheesy bite—you’ve earned it!
Pro Tips for Making Dad’s Creamy & Cheesy Au Gratin Potatoes
Making the perfect au gratin potatoes is easier than you might think with a few handy tips!
- Choose the right potatoes: Yukon Golds are ideal for this dish due to their creamy texture and buttery flavor, which enhance the overall taste of your au gratin.
- Slice evenly: Cutting the potatoes into even 1/8-inch slices ensures they cook uniformly. This prevents some slices from being undercooked while others are overdone.
- Don’t rush the sauce: Gradually whisking in the flour and milk helps create a smooth, lump-free sauce. This step is crucial for achieving that rich, creamy texture everyone loves.
- Layer thoughtfully: When arranging your potato and onion layers, leave some space between them. This allows for even cooking and ensures every bite is infused with flavor.
- Let it rest: After baking, let the dish sit for about 10 minutes before serving. This helps the layers set up a bit, making it easier to serve clean slices.

- Cracked black pepper: A light dusting of freshly cracked black pepper not only enhances flavor but also adds an appealing visual contrast on top of your creamy potatoes.
