How to Make Dad’s Creamy & Cheesy Au Gratin Potatoes
Step 1: Preheat the Oven
First things first! Preheat your oven to 375 degrees Fahrenheit. This ensures that when your dish goes in, it starts cooking right away for that perfect golden finish.
Step 2: Prepare the Baking Dish
Spray a 2-quart square baking dish (an 8×12 works well too) with nonstick cooking spray or grease it with butter or oil. This step is essential; it keeps those cheesy layers from sticking!
Step 3: Arrange the Potatoes and Onions
Now comes the fun part! Place your sliced potatoes in three tight slanted rows in the baking dish. Don’t rush this—you want them to be slightly slanted to allow even cooking. Sprinkle onion slices between and on top where you can fit them; they will add so much flavor as they cook down.
Step 4: Make Your Sauce
In a medium saucepan over medium heat, melt the butter. Once melted, whisk in a bit of flour at a time while slowly adding almond milk. Keep whisking until you eliminate any lumps—this helps achieve that velvety consistency we all crave! Bring this mixture to a gentle simmer; think creamy gravy texture.
Step 5: Add Cheese and Seasoning
Turn down the heat and stir in shredded cheddar cheese along with garlic powder, salt, and freshly ground black pepper. Taste as you go! Adjust seasoning if needed; this step brings out all those wonderful flavors.
Step 6: Pour Over Potatoes
Now pour your creamy sauce evenly over the arranged potatoes and onions. Don’t worry if it looks thin—it will thicken beautifully while baking!
Step 7: Bake Covered
Cover your baking dish with foil to help trap steam while baking. Pop it into the preheated oven for about 45 minutes.
Step 8: Add Toppings and Finish Baking
After 45 minutes, remove the foil carefully (watch out for steam!). Sprinkle gruyere cheese and parmesan over the top. Return to the oven without foil for another 30-45 minutes until everything is bubbly and golden brown on top. The potatoes are done when they’re tender enough to pierce with a fork.
Step 9: Garnish & Serve
Once out of the oven, sprinkle fresh chopped parsley on top for that lovely finishing touch. Now you’re ready to dig in! Enjoy every creamy bite of Dad’s Creamy & Cheesy Au Gratin Potatoes—your loved ones will be raving about them!
Pro Tips for Making Dad’s Creamy & Cheesy Au Gratin Potatoes
Making the perfect au gratin potatoes is all about attention to detail, and I’ve got some tips to help you achieve that creamy, cheesy goodness!
- Use Yukon Gold Potatoes: These potatoes have a naturally buttery flavor and creamy texture, making them ideal for au gratin dishes as they hold their shape while becoming tender.
- Layer the Ingredients: Take your time to layer the potatoes and onions tightly but not overcrowded. This ensures even cooking and allows the flavors to meld beautifully.
- Whisk Smoothly: When making the cheese sauce, whisk vigorously to prevent lumps. A smooth sauce is key to achieving that creamy consistency that coats each potato slice perfectly.
- Don’t Rush the Baking: Allow your dish to bake covered initially; this helps steam the potatoes until they are tender. Removing the foil later gives you that glorious golden brown finish on top.
- Taste and Adjust Seasoning: Always taste your cheese sauce before pouring it over the potatoes. Adjusting salt and pepper will enhance the overall flavor of your dish, making every bite delicious.
