INGREDIENTS You’ll Need:

- 1/4 cup All-Purpose Flour: Helps to thicken the sauce. I often use a gluten-free blend for added health.
- 3 cups Milk: I use whole milk for extra creaminess, but you can use any milk you prefer.
- 1 cup Heavy Cream: This is what makes the Cheesy Au Gratin Potatoes Recipe extra decadent.
- 4 cups Shredded Cheddar Cheese: Sharp cheddar is my go-to, but feel free to experiment with other cheeses.
- 2 tbsp Butter: Adds richness and flavor.
- 1 tsp Salt: Balances the flavors.

- In a large saucepan, melt the butter over medium heat. Add the sliced onions and cook until softened, about 5-7 minutes. Then, add the minced garlic and cook for another minute until fragrant.
- Stir in the flour and cook for 1-2 minutes, making sure there are no lumps. Slowly whisk in the milk and heavy cream until smooth.
- Bring the mixture to a simmer, stirring constantly until it starts to thicken slightly. This usually takes about 5-7 minutes.
- Remove the saucepan from the heat and stir in 3 cups of the shredded cheddar cheese, salt, pepper, and nutmeg until the cheese is melted and the sauce is smooth.
- Arrange a layer of potato slices in the prepared baking dish, overlapping them slightly. Pour about one-third of the cheese sauce over the potatoes.
- Repeat the layers with another layer of potatoes and cheese sauce. Finish with a final layer of potatoes and the remaining cheese sauce.
- Sprinkle the remaining 1 cup of shredded cheddar cheese over the top of the potatoes.
- Cover the baking dish with aluminum foil and bake for 45 minutes. Then, remove the foil and bake for another 15-20 minutes, or until the potatoes are tender and the cheese is golden brown and bubbly.
- Let the Cheesy Au Gratin Potatoes Recipe rest for about 10 minutes before serving. Garnish with fresh parsley, if desired. Enjoy your Cheesy Au Gratin Potatoes Recipe!
