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 step is crucial as it ensures even baking and helps achieve that perfect golden-brown top.
Step 2: Arrange the Potatoes
Spray a 2-quart square baking dish with nonstick cooking spray or grease it with butter or oil. Next, arrange the sliced potatoes in three tight slanted rows. Remember not to overcrowd them; they should have enough space so that each slice stands slightly slanted. Tuck onion slices between the rows and sprinkle them on top too; they add wonderful sweetness as they cook.
Step 3: Make Your Sauce
In a saucepan over medium heat, melt the butter. Once melted, whisk in a bit of flour before slowly adding almond milk. Alternate between adding flour and milk while whisking vigorously to avoid lumps. Bring this mixture to a gentle simmer until it thickens; think creamy gravy consistency! Stir in shredded cheddar cheese along with garlic powder, salt, and freshly ground black pepper.
Step 4: Combine
Pour that luscious sauce evenly over your arranged potatoes and onions. Don’t worry—the magic happens in the oven as everything bakes together!
Step 5: Bake Covered
Cover the pan with foil and let it bake for about 45 minutes. This step allows the potatoes to steam slightly before getting that crispy finish.
Step 6: Add Toppings
After 45 minutes, carefully remove the foil and sprinkle on gruyere cheese (or more cheddar) alongside parmesan cheese. Return it to the oven for an additional 30-45 minutes until everything is bubbling hot and beautifully golden brown on top.
Step 7: Serve & Enjoy
Once done, take them out of the oven and garnish with fresh chopped parsley for that pop of color! Serve warm and watch everyone fall in love with Dad’s Creamy & Cheesy Au Gratin Potatoes!
Pro Tips for Making Dad’s Creamy & Cheesy Au Gratin Potatoes
Making au gratin potatoes can be easy and fun with the right tips! Here are some helpful suggestions to ensure your dish turns out perfectly every time.
-
Choose the right potatoes: Yukon gold potatoes are ideal for this recipe due to their creamy texture and buttery flavor. They hold up well during baking and provide a deliciously smooth consistency.
-
Slice evenly: For the best results, make sure to slice your potatoes into 1/8-inch rounds consistently. This ensures even cooking, so every bite is tender and creamy.
-
Whisk vigorously: When making the sauce, whisking vigorously while adding milk and flour helps eliminate lumps, resulting in a velvety smooth cheese sauce that coats your potatoes beautifully.
-
Don’t skip the foil: Covering the dish with foil during the first half of baking traps steam, which helps cook the potatoes through evenly without drying them out. Just remember to remove it later for that crispy, golden top!
-
Let it rest: After baking, allow the dish to sit for about 10 minutes before serving. This resting period allows the layers to settle and makes serving easier!
