Ingredients
- 2 tbsp butter (plus extra for greasing the dish)
- 1/2 medium onion, minced
- 1 clove garlic, minced
- 1.25 tsp salt (for seasoning)
- 1/2 tsp ground black pepper (for seasoning)
- 3/4 cup chicken stock (for sauce)
- 1.25 cups heavy cream (for creamy texture)
- 1.5–1.75 lbs russet potatoes (about 5-6, peeled and sliced 1/8 inch thick)
- 3 cups shredded cheese (2 cups Cheddar, 3/4 cup Fontina or Provolone, and 1/4 cup Parmesan)
- 1 tbsp chopped parsley (for garnish)
Instructions
- Preheat the Oven: Preheat your oven to 425°F (220°C) to ensure even baking.
- Prepare the Butter and Onion: In a large skillet over medium heat, melt 2 tablespoons of butter. Add the minced onion and cook for about 5 minutes until soft. Then add garlic, salt, and pepper, cooking for an additional 30 seconds until fragrant.
- Combine Ingredients: Pour in the chicken stock and heavy cream, stirring to combine. Add the thinly sliced potatoes, ensuring they are well-coated in the sauce.
- Simmer the Potatoes: Increase the heat to bring the mixture to a simmer. Cover, reduce heat to medium-low, and cook until the potatoes are nearly tender, about 15-20 minutes, stirring occasionally.
- Prepare the Casserole Dish: Butter an 8×8-inch baking dish or five to six small individual dishes.
- Assemble the Dish: Transfer the potatoes and sauce to the prepared baking dish, spreading evenly. Top with an even layer of the shredded cheese mixture.
- Bake the Dish: Bake for 10-15 minutes, or until the cheese is melted and golden brown. Let the dish rest for a few minutes before serving.
- Garnish and Serve: Sprinkle with chopped parsley and serve warm. Enjoy!
Tips & Variations
- For a richer flavor, try using half-and-half instead of heavy cream, but the texture will be slightly lighter.
- Swap Fontina for Provolone if you prefer a milder cheese flavor.
- Use a mandoline slicer for uniformly thin potato slices to ensure even cooking.
- For extra crispiness, broil the cheese topping for 1-2 minutes at the end, watching closely to avoid burning.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven at 350°F (175°C) until warmed through to maintain the creamy texture and avoid sogginess.

FAQs
Can I make this dish ahead of time?
Yes, you can prepare the potatoes au gratin up to the point before baking and refrigerate it for a few hours or overnight. When ready, bake as directed, adding a few extra minutes if needed.
What type of potatoes work best?
Russet potatoes are ideal because their starchy texture helps create a creamy and tender dish. Avoid waxy potatoes, as they may not break down as well during cooking.

For the Potatoes and Topping

- 1 tbsp chopped parsley (for garnish)
Instructions
- Preheat the Oven: Preheat your oven to 425°F (220°C) to ensure it is hot and ready for the final baking step.
- Prepare the Butter and Onion: In a large skillet over medium heat, melt 2 tablespoons of butter. Add the minced onion and cook for about 5 minutes until soft and translucent. Then add the minced garlic, salt, and black pepper, cooking for an additional 30 seconds until fragrant.
- Combine Ingredients: Pour in the chicken stock and heavy cream, stirring well to combine. Add the thinly sliced potatoes to the skillet, stirring to coat them thoroughly in the sauce.
- Simmer the Potatoes: Turn up the heat to bring the mixture to a simmer. Cover the skillet, reduce the heat to medium-low, and cook the potatoes for about 15-20 minutes, stirring occasionally, until the potatoes are nearly tender but not fully cooked through.
- Prepare the Casserole Dish: Butter an 8×8-inch baking dish or five to six small individual baking dishes to prevent sticking and add richness.

Notes
- Use russet potatoes for the best creamy texture and absorption of the sauce.
- Slicing the potatoes thinly (1/8 inch) ensures they cook evenly and meld with the creamy sauce.
- You can substitute Fontina with Provolone if desired; both melt well and offer a mild flavor.
- For a vegetarian version, replace chicken stock with vegetable broth.
- Allow the potatoes to rest after baking; this helps the sauce thicken for perfect consistency.
