How to Make Dad’s Creamy & Cheesy Au Gratin Potatoes
Step 1: Preheat Your Oven
Begin by preheating your oven to 375 degrees F. This step ensures that your dish cooks evenly and achieves that perfect golden brown top.
Step 2: Arrange the Potatoes and Onions
Spray your baking dish with nonstick cooking spray or grease it with butter. Then, layer the sliced potatoes in three tight slanted rows. Don’t pack them too tightly; they need space for even cooking! Sprinkle onion slices between the rows and on top of the potatoes for added flavor.
Step 3: Make the Sauce
In a saucepan over medium heat, melt your butter. Once melted, whisk in a bit of flour before slowly adding in almond milk while continuously whisking to avoid lumps. Bringing this mixture to a simmer gives you that creamy gravy-like consistency that will coat your potatoes beautifully.
Step 4: Add Cheese and Seasonings
Reduce the heat to low and stir in your shredded cheddar cheese along with garlic powder, salt, and pepper. Taste your sauce—this is where you can adjust seasoning as needed to make it just right!
Step 5: Pour Over Potatoes
Carefully pour your creamy sauce over the arranged potatoes and onions. Don’t worry if it seems thin; it will thicken as it bakes.
Step 6: Bake Covered
Cover your baking dish with foil and bake for 45 minutes. This helps steam the potatoes until they’re tender.
Step 7: Add Toppings and Finish Baking
After 45 minutes, remove the foil and sprinkle gruyere cheese (or more cheddar) along with parmesan on top. Return it to the oven for another 30-45 minutes until golden brown. You’ll know it’s done when you can easily pierce through the middle of the potato layers with a fork.
Step 8: Garnish and Serve
Once out of the oven, garnish with fresh chopped parsley for color and freshness. Serve warm and enjoy every cheesy bite together!
Pro Tips for Making Dad’s Creamy & Cheesy Au Gratin Potatoes
Making the perfect au gratin potatoes can be a breeze with just a few helpful tips!
-
Choose the right potatoes: Yukon gold potatoes are ideal for this dish because they have a creamy texture and hold their shape well during baking, ensuring your au gratin remains hearty and flavorful.
-
Slice evenly: Aim for uniform 1/8-inch slices. This helps ensure that all the potato slices cook evenly, resulting in a creamy consistency throughout the dish.
-
Don’t skip the resting time: Allowing the au gratin to rest for at least 10-15 minutes after baking helps the flavors meld together beautifully and makes it easier to serve.
-
Experiment with cheeses: While sharp cheddar and gruyere provide great flavor, feel free to mix in other cheeses like fontina or mozzarella for added creaminess and complexity.
-
Adjust seasoning to taste: Everyone’s palate is different! Before pouring the sauce over your potatoes, taste it and adjust the salt and pepper according to your family’s preference for a perfectly seasoned dish.
