1. Prepare the Ingredients:
- Slice Potatoes and Onion: Use a mandoline slicer to thinly slice the potatoes and onion for even cooking.
- Heat Cream Mixture: In a medium saucepan, heat the heavy cream, milk, butter, minced garlic, salt, pepper, and thyme over medium heat until the butter is melted and the mixture is warmed through. Do not let it boil. Remove from heat.
2. Assemble the Scalloped Potatoes:
- Layer Potatoes and Onion: In an air fryer-safe dish or cake pan that fits your air fryer, start by layering a portion of the sliced potatoes on the bottom. Follow with a layer of sliced onions. Repeat layers until all the potatoes and onions are used.
- Add Cream Mixture: Pour the warm cream mixture over the layered potatoes and onions, making sure it covers all the layers.
- Top with Cheese: Sprinkle the shredded cheddar cheese and grated Parmesan cheese evenly over the top.
3. Air Fry the Scalloped Potatoes:
- Preheat Air Fryer: Preheat your air fryer to 350°F (175°C) for about 5 minutes.
- Prepare Basket: Lightly spray the air fryer basket with olive oil spray to prevent sticking.
- Cook: Place the dish with the potatoes in the air fryer basket. Air fry at 350°F (175°C) for 30-40 minutes, or until the potatoes are tender and the top is golden brown and crispy. If the top starts to brown too quickly, cover with aluminum foil and continue cooking until the potatoes are done.
4. Serve:
- Garnish: Remove the scalloped potatoes from the air fryer and let them cool for a few minutes. Garnish with chopped fresh parsley, if desired.
- Enjoy: Serve the scalloped potatoes hot as a side dish or a main course.
Tips for Perfect Air Fryer Scalloped Potatoes:
- Even Slices: Ensure the potatoes are sliced evenly for consistent cooking. A mandoline slicer is ideal for this.
- Cheese Variation: Feel free to use other types of cheese like Gruyere or Fontina for a different flavor profile.
- Cooking Time: Air fryer models vary, so check the potatoes for doneness by inserting a fork. If they are tender and the top is golden, they are ready.
