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 cook evenly once they’re ready to go in!
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 helps prevent sticking and makes cleanup easier later on.
Step 3: Arrange the Potatoes
Place the sliced potatoes in three tight slanted rows in your baking dish. Make sure they’re not too crowded; leaving some space allows them to cook perfectly! Sprinkle the onion slices between and on top of the potato layers for added flavor.
Step 4: Make Your Sauce
In a saucepan over medium heat, melt the butter. Once melted, whisk in a bit of flour, then slowly add almond milk while alternating with flour. This technique helps avoid lumps and creates a smooth sauce. Bring it to a simmer until it thickens slightly—aiming for a consistency similar to creamy gravy is perfect!
Step 5: Add Cheese and Seasoning
Lower the heat and stir in shredded cheddar cheese along with garlic powder, salt, and freshly ground black pepper. Give everything a taste and adjust seasoning as needed—this is where you can make it just right!
Step 6: Pour Over Potatoes
Evenly pour your creamy cheese sauce over the arranged potatoes and onions. Don’t worry if they aren’t completely submerged; they will absorb all that deliciousness while baking!
Step 7: Bake Covered
Cover your baking dish tightly with foil and bake for about 45 minutes. This allows the potatoes to soften beautifully without drying out.
Step 8: Finish Baking Uncovered
After 45 minutes, remove the foil and sprinkle gruyere cheese (or more cheddar) along with parmesan on top. Return it to the oven uncovered for another 30-45 minutes until golden brown on top and fork-tender in the middle—perfection!
Step 9: Garnish & Serve
Once out of the oven, garnish your creation with fresh chopped parsley for a pop of color. Now it’s time to dig into Dad’s Creamy & Cheesy Au Gratin Potatoes—enjoy every cheesy bite!
Pro Tips for Making Dad’s Creamy & Cheesy Au Gratin Potatoes
Making the perfect au gratin potatoes is all about those little details that can elevate your dish from good to unforgettable!
-
Choose the right potatoes: Yukon gold potatoes are ideal due to their creamy texture and buttery flavor. They hold their shape during cooking, providing a great base for your cheesy sauce.
-
Layer thoughtfully: When arranging the potato slices, make sure they are slightly slanted and not too tightly packed. This allows for even cooking and ensures that every slice absorbs the delicious sauce.
-
Whisk vigorously: When making your cheese sauce, whisking well helps to eliminate lumps and creates a smoother consistency. This is key to achieving that luxurious creaminess we all love in au gratin potatoes.
-
Don’t skip the foil: Covering your baking dish with foil during the first part of baking traps steam, which helps cook the potatoes thoroughly without burning the top. Remove it later for that golden crust!
-
Let it rest before serving: Allowing the dish to sit for about 10 minutes after baking helps thicken up the sauce and makes it easier to serve. Plus, it gives you time to set the table!
