In a bowl, whisk eggs with sour cream, Italian seasoning, chili powder, salt and pepper.
Divide diced ham between muffin cups or ramekins (I used ½ cup silicone muffin molds). Add cherry tomatoes, jalapeno slices, and shredded Cheddar to each ramekin. Pour beaten eggs on top.
Preheat your air fryer to 300F.
Air fry egg bites for 10 minutes. Open the air fryer and sprinkle each bite with shredded Cheddar. Continue to cook for 2-3 more minutes or until the eggs are set and cheese melts.
