This hearty air fryer diced potatoes recipe has become my family's go-to side dish for everything from quick weeknight dinners to weekend brunches. The perfect combination of crispy exteriors and fluffy interiors makes these potatoes irresistible every time.
The first time I served these at brunch, my guests couldn't believe they weren't deep-fried. The secret lies in the perfect cube size and temperature control.
Ingredients
- Potatoes: Choose firm, unblemished russets or Yukons
- Butter: Unsalted, melted but not too hot
- Cajun Seasoning: Make your own blend for freshest flavor
- Salt: Fine sea salt distributes most evenly
- Optional additions: Garlic powder, paprika, or herbs
- Cooking spray: Light coating for extra crispiness
Step-by-Step Instructions

- Perfect Potato Prep:
- Wash potatoes thoroughly. Cut into uniform ½-inch cubes. Soak in cold water for 15 minutes. Dry completely with clean kitchen towels. Let air dry for 5 minutes.
- Seasoning Technique:
- Toss potatoes with melted butter first. Add seasonings gradually while tossing. Ensure even coating on all sides. Let stand 5 minutes to absorb flavors. Reserve some seasoning for finishing.
- Air Fryer Method:
- Preheat completely to 375°F. Arrange potatoes in single layer. Leave space between pieces. Avoid overcrowding at all costs. Spray basket lightly with oil.
- Cooking Process:
- Check at 10-minute mark. Shake basket to redistribute. Watch for golden edges. Test for doneness with fork. Adjust time based on size.
- Final Touches:
- Season while still hot. Toss gently to maintain shape. Let rest 3-5 minutes. Add fresh herbs if using. Serve immediately for best texture.
My family's weekend tradition includes these potatoes with eggs and bacon - the perfect combination of crispy and savory breakfast flavors.
Temperature Management
The key to perfectly crispy diced potatoes lies in maintaining consistent temperature. I've found that 375°F provides the ideal balance between crispy exterior and tender interior.
Storage Solutions
These potatoes can be stored in the refrigerator for up to three days in an airtight container. To reheat, pop them back in the air fryer for 3-5 minutes at 350°F or use a toaster oven. While they won't be quite as crispy as fresh, they'll still maintain much of their texture. I often make double batches specifically for leftovers.
Creative Variations
While the Cajun seasoning is my go-to flavor, these potatoes are incredibly versatile. Try Italian seasoning with grated parmesan cheese, or go for ranch seasoning with a sprinkle of dill. For breakfast potatoes, add onion powder and paprika. My children's favorite version includes a light dusting of taco seasoning and a sprinkle of cheese in the last minute of cooking.
Serving Suggestions
These crispy potato cubes shine as a breakfast side with scrambled eggs, but they're equally impressive alongside a juicy steak or rotisserie chicken. For a complete meal, I often serve them with a simple green salad and grilled protein. They also make an excellent base for loaded potato bowls - just top with cheese, sour cream, bacon bits, and green onions.

These air fryer diced potatoes are sure to become a staple in your kitchen. Perfectly crispy and packed with flavor!
