This Potatoes au Gratin is very comforting, creamy, and seriously cheesy. This copycat is homey, a little chunky with tons of cheese! Everything about this Potatoes au Gratin is perfect!



1 1/2 pounds russet potatoes, peeled and sliced 1/8-inch thick

2 tbsp butter, plus more for greasing the baking dish

2 garlic cloves, minced

1/2 white onion, minced

1/2 c. chicken stock

1 1/4 c. heavy cream, plus more if needed

2 c. cheddar cheese, grated

1/2 c. Parmesan cheese, grated

3/4 c. provolone cheese, grated

Fresh parsley, chopped, for garnish

1 1/2 tsp salt

1/2 tsp freshly ground black pepper


Set the oven to 425 degrees F. Using butter, grease an 8 x 8-inch baking dish.

Melt the butter in a large pot on medium heat. To the melted butter, add the onion and saute for about 5 minutes until tender and translucent. Next, add the garlic and sprinkle with salt and pepper. Cook for additional 30 seconds.

Pour in the stock and cream. Add the potatoes, stir, and bring everything to a low simmer. DO NOT BOIL. Put the lid on and adjust the heat to medium-low. Cook for another 15 to 20 minutes or until the potatoes are tender. As needed, adjust the seasoning to your liking.

To the prepared baking dish, transfer the mixture and sprinkle the grated cheeses on top.

Place in the preheated oven and bake for about 10 to 15 minutes or until the cheese is bubbly and melted.

Remove from the oven and serve the Potatoes au Gratin right away garnished with some parsley (optional). Enjoy!
