Essential Ingredients
Here’s what you’ll need to make this delicious dish:
Russet Potatoes: These starchy potatoes are perfect for achieving that creamy texture while maintaining structure.
Heavy Cream: A must-have for that silky richness; don’t skimp here—it’s worth it!
Sharp Cheddar Cheese: Choose a good-quality cheese for maximum flavor impact; extra sharp adds a delightful tang.
Garlic: Fresh garlic cloves enhance depth; they pair beautifully with potatoes and cream.
Butter: Use unsalted butter for cooking; it adds richness without overwhelming other flavors.
Salt and Pepper: Essential seasonings to bring all the flavors together; adjust according to taste.
The full ingredients list, including measurements, is provided in the recipe card directly below.
Let’s Make it Together
Preheat your oven: Start by preheating your oven to 375°F (190°C). This sets the stage for that heavenly golden crust we all crave.
Prepare the potatoes: Peel and slice your russet potatoes thinly—about 1/8 inch thick works best. Aim for uniform slices so they cook evenly.
Sauté garlic in butter: In a skillet over medium heat, melt 2 tablespoons of unsalted butter and add minced garlic. Sauté until fragrant but not browned—around one minute should do!
Layer the ingredients: In a greased baking dish, layer half of the potato slices evenly across the bottom. Sprinkle salt and pepper before drizzling half of the heavy cream over them.
Add cheese: Generously sprinkle half of your sharp cheddar cheese over the potatoes. Repeat layering with remaining potatoes, seasoning, cream, and cheese.
Bake to perfection: Cover your baking dish with aluminum foil and bake for 45 minutes. Remove foil and bake an additional 15-20 minutes until bubbly and golden brown.
Let it rest: Once out of the oven, allow your potato au gratin to rest for about 10 minutes before serving. This helps set everything nicely so you can cut perfect slices.
And there you have it! A rich, cheesy potato au gratin that will elevate any meal from average to extraordinary in no time flat!
