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 that your au gratin potatoes cook evenly and become perfectly golden on top.
Step 2: Arrange the Potatoes
Spray a 2-quart square baking dish with nonstick cooking spray or grease it with butter. Place your sliced potatoes in three tight slanted rows, leaving enough space between them so they cook through without getting mushy. Scatter onion slices in between and on top of the potatoes – they add fantastic flavor!
Step 3: Make the Sauce
In a saucepan over medium heat, melt the butter. Gradually whisk in flour, alternating with almond milk while whisking vigorously to avoid lumps. This creates a smooth sauce similar to creamy gravy – delicious! Bring this mixture to a simmer until thickened.
Step 4: Add Cheese & Seasoning
Once your sauce has thickened, lower the heat and stir in shredded cheddar cheese along with garlic powder, salt, and pepper. Taste and adjust seasoning as needed; this step infuses flavor into your sauce!
Step 5: Combine Everything
Pour the creamy cheese sauce evenly over the arranged potatoes and onions. Don’t fret if it looks like too much; the sauce will seep into every nook while baking!
Step 6: Bake Covered
Cover your baking dish with foil and bake for about 45 minutes. This helps steam the potatoes until they’re tender.
Step 7: Add Toppings & Finish Baking
After removing the foil, sprinkle gruyere cheese and parmesan on top. Return to the oven for another 30-45 minutes or until golden brown and bubbly on top. You’ll know they’re done when you can easily pierce through the middle with a fork.
Step 8: Garnish & Enjoy!
Once out of the oven, sprinkle fresh chopped parsley over the top for color and freshness before serving up these delicious au gratin potatoes! Enjoy every creamy, cheesy bite!
Pro Tips for Making Dad’s Creamy & Cheesy Au Gratin Potatoes
Making perfect au gratin potatoes is all about attention to detail and a pinch of love. Here are some pro tips to ensure your dish turns out creamy and cheesy every time!
-
Use uniform potato slices: Cutting the potatoes into even 1/8-inch rounds ensures they cook evenly. This means no mushy or undercooked bites, giving you that perfect creamy texture throughout.
-
Layer wisely: When layering the potatoes and onions, be mindful of leaving some space between the slices. This not only helps with even cooking but also allows the sauce to seep in fully, enhancing that delightful flavor.
-
Don’t rush the sauce: When making the cheese sauce, take your time whisking in the flour and milk slowly. This prevents lumps from forming and gives you a smooth, creamy sauce that coats the potatoes beautifully.
-
Taste as you go: Always taste your cheese sauce before pouring it over the potatoes. Adjusting salt and pepper at this stage ensures your dish has a balanced flavor that everyone will enjoy.
-
Let it rest before serving: After baking, allow your au gratin potatoes to sit for about 10 minutes before serving. This helps set the layers and makes it easier to serve while maintaining that wonderful creaminess.
