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 ensures that your dish bakes evenly and comes out perfectly golden brown after cooking.
Step 2: Arrange the Potatoes and Onions
Spray your baking dish with nonstick cooking spray or grease it lightly with butter or oil. Layer your sliced potatoes in three tight slanted rows. Don’t crowd them too much; they need room to cook properly. Place onion slices between the rows where you can fit them—this adds even more flavor!
Step 3: Make Your Sauce
In a saucepan over medium heat, melt the butter. Once melted, whisk in a little flour at first, then slowly add the almond milk while continuing to whisk vigorously. This helps prevent lumps from forming. As it heats up, it should resemble creamy gravy—this is what gives you those dreamy au gratin textures!
Step 4: Add Cheese and Seasonings
Reduce the heat to low and stir in the shredded cheddar cheese along with garlic powder, salt, and freshly ground black pepper. Give it a taste—if you love cheesy goodness like I do, you might want to add just a pinch more salt!
Step 5: Pour Sauce Over Potatoes
Carefully pour your cheesy sauce over the arranged potatoes and onions until they’re covered. Don’t worry if it looks like there’s too much sauce—it will thicken beautifully as it bakes.
Step 6: Bake Covered
Cover your baking dish with foil and pop it into the oven for about 45 minutes. This helps steam the potatoes so they become tender without burning.
Step 7: Add Toppings and Finish Baking
After 45 minutes, remove the foil and sprinkle the top with gruyere cheese (or more cheddar) and parmesan. Return it to the oven for another 30-45 minutes until everything is bubbly and golden brown on top. You’ll know they’re done when you can easily pierce through the center with a fork.
Step 8: Garnish and Enjoy!
Once out of the oven, sprinkle fresh chopped parsley over your creamy masterpiece for color—and enjoy every cheesy bite with family or friends!
Pro Tips for Making Dad’s Creamy & Cheesy Au Gratin Potatoes
Making the perfect creamy and cheesy au gratin potatoes is all about attention to detail and a few little tweaks. Here are some handy tips to ensure your dish turns out heavenly!
-
Choose the right potatoes: Yukon gold potatoes work best due to their creamy texture and natural sweetness, which enhances the overall flavor of the dish.
-
Slice evenly: Aim for thin, uniform slices (about 1/8 inch thick) to ensure even cooking. This prevents some pieces from being undercooked while others become mushy.
-
Layer smartly: Lay your potato slices in a slightly slanted manner, allowing for better sauce distribution and a beautiful presentation. This helps each layer soak up that cheesy goodness!
-
Taste as you go: Always taste your cheese sauce before pouring it over the potatoes. Adjusting salt and pepper at this stage ensures every bite is perfectly seasoned.
-
Let it rest: Allow the au gratin potatoes to sit for about 10-15 minutes after baking. This helps the layers set and makes serving easier while enhancing the flavors.
