Air Fryer Au Gratin Potatoes
Creamy, cheesy layers of potatoes cooked to perfection in your air fryer.
🥔 Ingredients:
-
2–3 medium Yukon gold or russet potatoes, thinly sliced (about 1/8″ thick)
-
2 tablespoons butter
-
2 tablespoons all-purpose flour
-
1 cup milk (whole or 2%)
-
½ cup heavy cream (or more milk)
-
1 cup shredded sharp cheddar cheese
-
½ cup shredded mozzarella or Gruyère (optional)
-
½ teaspoon garlic powder
-
Salt & pepper to taste
-
Optional: ¼ teaspoon paprika or thyme for seasoning
-
Nonstick spray or oil (for greasing the dish)
-
Optional: 2 tablespoons grated Parmesan (for the top)
🍳 Instructions:
1. Make the Cheese Sauce
-
In a saucepan over medium heat, melt the butter.
-
Whisk in the flour and cook for 1 minute to form a roux.
-
Slowly add the milk and cream, whisking constantly until smooth and slightly thickened (3–5 minutes).
-
Stir in cheddar, mozzarella (if using), garlic powder, salt, pepper, and optional paprika. Stir until cheese is melted and sauce is smooth. Remove from heat.
2. Assemble the Potatoes
-
Spray a small oven-safe baking dish (that fits your air fryer basket) with nonstick spray or oil.
-
Layer half of the sliced potatoes in the dish.
-
Pour over half the cheese sauce.
-
Add remaining potatoes and top with the rest of the sauce.
-
Sprinkle with Parmesan if desired.
3. Air Fry
-
Preheat air fryer to 350°F (175°C) for 3 minutes.
-
Cover the dish with foil and place it in the air fryer basket.
-
Air fry at 350°F for 25 minutes covered.
-
Remove foil and air fry another 10–15 minutes, or until:
-
Potatoes are tender
-
Top is golden brown and bubbly
-
4. Cool and Serve
-
Let sit for 5–10 minutes before serving so the sauce thickens slightly.
✅ Tips:
-
Slice potatoes evenly for even cooking. Use a mandoline if you have one.
-
If using russet potatoes, soak in water for 10 minutes and pat dry to remove excess starch (for better texture).
-
Add a sprinkle of chives or bacon bits on top before serving for a deluxe finish.
