How to Make Dad’s Creamy & Cheesy Au Gratin Potatoes
Step 1: Preheat Your Oven
Preheat your oven to 375 degrees F. This ensures it’s hot enough when your au gratin goes in. A well-heated oven helps achieve that golden-brown topping we all love!
Step 2: Prepare the Baking Dish
Spray a 2-quart square baking dish (or an 8×12 dish) with nonstick cooking spray or grease it lightly with butter or oil. This step is important because it helps prevent sticking and makes serving easier later.
Step 3: Layer the Potatoes and Onions
Arrange sliced potatoes in three tight slanted rows in the baking dish. Leave enough space so they can cook evenly. Nestle onion slices between the layers wherever you can fit them — they’ll add great flavor as they bake!
Step 4: Make Your Sauce
In a medium saucepan over medium heat, melt 2 tablespoons of butter. Once melted, whisk in a bit of flour before slowly adding almond milk while whisking vigorously. This technique helps avoid lumps and creates a smooth sauce. Bring it to a simmer until thickened; you want it similar in consistency to creamy gravy.
Step 5: Add Cheese and Seasoning
Once your sauce has thickened, lower the heat and stir in shredded cheddar cheese along with garlic powder, salt, and pepper. Taste your sauce; don’t hesitate to add more seasoning if needed! This step adds depth of flavor that will permeate throughout the potatoes.
Step 6: Pour Over Potatoes
Pour that luscious cheese sauce evenly over your layered potatoes and onions—don’t stress if some bits are still peeking through; they’ll get plenty creamy as they bake!
Step 7: Bake Covered
Cover your pan tightly with foil and bake for 45 minutes. The cover traps steam inside, helping cook those potatoes through beautifully.
Step 8: Add Toppings and Finish Baking
After removing the foil, sprinkle gruyere cheese (or more cheddar) and parmesan on top. Return it to the oven for another 30-45 minutes until everything is bubbling hot and golden brown on top. You’ll know they’re done when you can easily pierce the center of the potatoes with a fork.
Step 9: Serve & Enjoy!
Once out of the oven, garnish generously with fresh chopped parsley for that pop of color! Serve warm alongside your favorite main dishes — enjoy every cheesy bite!
