How to Make Cheesy Potatoes Au Gratin
-
Preheat oven: Begin by preheating your oven to 375°F (190°C) and lightly butter a 9×13-inch baking dish, ensuring your delicious creation won’t stick.
-
Slice potatoes: Peel and thinly slice the potatoes to 1/8 inch thickness. This helps them cook evenly and absorb the creamy sauce beautifully.
-
Create roux: In a medium saucepan, melt 3 tablespoons of unsalted butter over medium heat. Whisk in the flour to create a roux and cook for 1 minute, allowing the flour to lose its raw taste.
-
Add dairy: Gradually whisk in the whole milk and heavy cream, stirring constantly until the mixture thickens—this should take about 3-5 minutes. Aim for a smooth, creamy texture.
-
Season sauce: Stir in the garlic powder, onion powder, salt, and pepper. Reduce the heat and add the sharp cheddar and Gruyère cheese, melting them into a velvety cheese sauce.
-
Layer ingredients: In the prepared baking dish, layer one-third of the sliced potatoes, then cover with one-third of the cheese sauce. Repeat this process for two more layers, finishing with the remaining cheese sauce on top.
-
Bake covered: Sprinkle the extra cheddar cheese over the top. Cover the dish with foil and bake for 45 minutes, then remove the foil and bake for an additional 20-25 minutes until the dish is golden brown and bubbly.
-
Finish and serve: Allow the dish to cool for 10-15 minutes. Highlight the crispy bacon over the top and, if desired, broil for 2-3 minutes for an extra crunch.
Optional: Garnish with fresh parsley for a pop of color and freshness.

Tips for the Best Cheesy Potatoes Au Gratin
-
Use Fresh Cheese: Freshly shredded cheese melts more smoothly than pre-shredded varieties, enhancing the creamy texture of your Cheesy Potatoes Au Gratin.

Prevent Browning: To avoid potato oxidation, soak the sliced potatoes in cold water until you’re ready to layer them in the dish. This keeps them from turning brown and maintains their vibrant color.
-
Consider Cheese Choices: Feel free to mix and match cheeses! While sharp cheddar is delightful, combining Gruyère with mozzarella or Fontina can elevate your Cheesy Potatoes Au Gratin with diverse flavors.

Mind the Baking Time: Every oven is different, so check if your dish is bubbling and golden brown after the suggested baking time. If not, extend it by a few minutes.
