How to Make Dad’s Creamy & Cheesy Au Gratin Potatoes
Step 1: Preheat Your Oven
Start by preheating your oven to 375 degrees F. This ensures that your au gratin potatoes bake evenly and achieve that perfect golden crust.
Step 2: Prepare the Baking Dish
Spray a 2-quart square baking dish (or an 8×12) with nonstick cooking spray or grease it with butter or oil. This step is crucial as it prevents sticking and makes clean-up easier later on.
Step 3: Layer the Potatoes and Onions
Arrange your sliced potatoes in three tight slanted rows in the baking dish. Don’t overcrowd them; they should be snug yet slightly slanted. Nestle onion slices between the potato rows so they can caramelize beautifully while baking.
Step 4: Make the Cheese Sauce
In a saucepan over medium heat, melt your butter. Once melted, whisk in a little bit of flour before gradually adding the almond milk while whisking vigorously to avoid lumps. Bring this mixture to simmer until it thickens slightly, resembling creamy gravy.
Step 5: Add Cheese and Seasonings
Lower the heat and stir in your shredded cheddar cheese along with garlic powder, salt, and pepper. This step is where all that cheesy goodness comes together! Taste it and adjust seasoning if needed—trust me, you’ll want it just right.
Step 6: Pour Over Potatoes
Pour this heavenly sauce evenly over your layered potatoes and onions. Don’t fret; they’ll soak up all that creamy goodness while baking!
Step 7: Bake Covered
Cover your dish tightly with foil and let it bake for about 45 minutes. This helps steam the potatoes until tender.
Step 8: Add Toppings
After 45 minutes, remove the foil and sprinkle gruyere cheese and parmesan on top. Return it to bake uncovered for another 30-45 minutes until golden brown on top and fork-tender inside.
Step 9: Garnish and Serve
When it’s done baking, remove it from the oven and garnish with fresh chopped parsley before serving. And there you have it—Dad’s Creamy & Cheesy Au Gratin Potatoes ready to delight everyone at your table! Enjoy every cheesy bite!
Pro Tips for Making Dad’s Creamy & Cheesy Au Gratin Potatoes
Making the perfect au gratin potatoes is all about technique and a little love—let’s elevate your dish to perfection!
- Choose the right potatoes: Yukon gold potatoes are ideal due to their creamy texture and buttery flavor. They hold up well during baking, ensuring each bite is tender and delicious.
- Layer thoughtfully: Arranging the potato slices in slanted rows not only looks beautiful but also allows for even cooking and sauce distribution. This ensures every slice gets that creamy goodness!
- Whisk out lumps: When making the cheese sauce, whisk vigorously while adding flour and milk. This prevents lumps, leading to a smooth, velvety sauce that coats the potatoes perfectly.
- Taste as you go: Don’t hesitate to taste your sauce before pouring it over the potatoes. Adjusting salt and pepper at this stage means you’ll achieve your desired flavor profile throughout the dish.
- Let it rest: After baking, allow the dish to rest for a few minutes before serving. This helps the layers settle and makes it easier to serve without falling apart!
