Ingredients (Serves 4–6)
Potatoes
- 1 kg potatoes (starchy or all-round potatoes work best, such as Russet, Yukon Gold, or Maris Piper)
Dairy
- 1 cup heavy cream
- 1/2 cup whole milk
- 2 tablespoons butter
Cheese (You can adjust types, but keep the total amount)
- 1 cup shredded cheddar cheese
- 1/2 cup shredded mozzarella cheese
- 1/2 cup grated parmesan cheese
Seasonings
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon garlic powder (or 2 cloves fresh garlic, finely minced)
- 1/2 teaspoon onion powder
- 1/4 teaspoon paprika
- Optional: pinch of nutmeg (classic for creamy potato dishes)
Optional Add-Ins (Choose only if you want extra flavor)
- 1/2 cup cooked bacon bits
- 1/2 cup caramelized onions
- Fresh herbs like thyme or parsley (for topping at the end)
Equipment Needed
- Air fryer
- Air fryer-safe baking dish or pan (metal or ceramic)
- Sharp knife or mandoline slicer
- Mixing bowl
- Small saucepan
- Aluminum foil
Step 1: Prepare the Potatoes
- Wash and peel the potatoes.
- Slice them very thin, about 2–3 mm thick. Even thickness is extremely important so they cook evenly.
- Place the sliced potatoes in a bowl of cold water for 10 minutes. This removes excess starch and helps prevent gumminess.
- Drain the potatoes and pat them completely dry with a clean towel.
Step 2: Make the Creamy Sauce
- In a small saucepan over low heat, add the butter, cream, and milk.
- Warm gently until the butter melts. Do not boil.
- Stir in salt, pepper, garlic powder, onion powder, paprika, and nutmeg.
- Remove from heat once everything is combined and warm.
Step 3: Preheat the Air Fryer
- Preheat the air fryer to 170°C (340°F) for about 5 minutes.
- This ensures even cooking from the start.
Step 4: Assemble the Potato Bake
- Grease your air fryer-safe dish lightly with butter or oil.
- Arrange a single layer of potato slices at the bottom, slightly overlapping.
- Spoon a small amount of cream sauce over the potatoes.
- Sprinkle a mix of cheddar, mozzarella, and parmesan.
- Repeat layers until all potatoes are used, ending with sauce and cheese on top.
- If using bacon or caramelized onions, add them between layers.
Step 5: First Cook (Covered)
- Cover the dish tightly with aluminum foil.
- Place it in the air fryer basket.
- Cook at 170°C (340°F) for 35–40 minutes.
- Halfway through, carefully remove and rotate the dish if your air fryer heats unevenly.
This step allows the potatoes to soften and absorb the cream.
Step 6: Second Cook (Uncovered)
- Remove the foil.
- Increase temperature to 190°C (375°F).
- Cook for another 12–15 minutes until the top is golden, bubbling, and lightly crisped.
If the top browns too quickly, lower the temperature slightly.
Step 7: Resting Time (Very Important)
- Remove the dish from the air fryer.
- Let it rest for 10–15 minutes before serving.
This allows the sauce to thicken and the layers to set, making clean slices possible.
Texture and Flavor Notes
- Inside should be soft, creamy, and rich.
- The top should be golden with slightly crisp edges.
- The parmesan adds saltiness, cheddar adds sharpness, and mozzarella gives stretch.
