How to Make Dad’s Creamy & Cheesy Au Gratin Potatoes
Step 1: Preheat Your Oven
First things first! Preheat your oven to 375 degrees F. This sets the stage for perfectly baked potatoes. While it heats up, spray a 2-quart square baking dish with nonstick cooking spray or grease it with butter or oil.
Step 2: Assemble the Potatoes and Onions
Now it’s time to layer those beautiful potato slices! Place them in three tight slanted rows in your baking dish. Be sure not to pack them too tightly—leave enough space so they can cook evenly. Sprinkle the onion slices in between and on top; they’ll add flavor as they bake.
Step 3: Make the Sauce
In a medium saucepan over medium heat, melt your butter. Once melted, whisk in a bit of flour followed by slowly adding the almond milk. This technique helps prevent lumps from forming—trust me; we want smooth sauce here! Stir until it simmers and thickens—it should be reminiscent of creamy gravy.
Step 4: Add Cheese and Seasonings
Turn down the heat and stir in that glorious shredded cheddar along with garlic powder, salt, and freshly ground black pepper. Taste your sauce! If you think it needs more salt or pepper, feel free to adjust until it’s just right.
Step 5: Pour Over Potatoes
Pour your rich sauce evenly over those stacked potatoes and onions. Don’t worry if everything doesn’t look perfect; as they bake, they will become beautifully creamy!
Step 6: Bake Covered
Cover the pan with foil and pop it into your preheated oven for about 45 minutes. This initial baking helps soften those potatoes perfectly.
Step 7: Add Toppings and Finish Baking
After 45 minutes, take off the foil. Now sprinkle that luscious gruyere cheese (or more cheddar if you prefer) along with grated parmesan on top. Bake uncovered for another 30-45 minutes until everything is golden brown and bubbly. The true test? A fork should easily pierce through those tender potatoes!
Once it’s out of the oven, don’t forget to sprinkle with fresh chopped parsley before serving. Enjoy every cheesy bite!
Pro Tips for Making Dad’s Creamy & Cheesy Au Gratin Potatoes
Creating the perfect au gratin potatoes is all about technique and a little love! Here are some expert tips to ensure your dish turns out creamy, cheesy, and absolutely delicious:
-
Choose the Right Potatoes: Yukon golds are ideal due to their creamy texture and buttery flavor. They hold their shape well during baking while absorbing flavors beautifully.
-
Slice Evenly: Keep your potato slices uniform at 1/8 inch thick for even cooking. This ensures all the potatoes become tender at the same time, giving you that perfect melt-in-your-mouth experience.
-
Simmer the Sauce: Allow your sauce to come to a gentle simmer before adding cheese. This helps thicken it while ensuring your cheese melts smoothly without clumping.
-
Don’t Skip the Foil: Covering your baking dish with foil during the first part of cooking traps steam and helps cook the potatoes through. Removing it later allows for that beautiful golden crust to form.
-
Let It Rest: After baking, give the dish a few minutes to cool before serving. This resting period allows flavors to meld and makes cutting easier!
