Start by preheating your air fryer to 300°F (150°C). This step is crucial as it ensures your scrambled eggs cook evenly and thoroughly.
In a mixing bowl, crack all 6 eggs. Add in the butter, salt, and pepper. Use a whisk or fork to beat the eggs until the mixture is well combined and slightly frothy.
Fold in the shredded cheddar cheese into the egg mixture. This will melt beautifully during cooking, adding a rich flavor to your scrambled eggs.
Lightly grease the air fryer basket with a bit of cooking spray or a small amount of butter. Pour the egg mixture into the basket, spreading it out evenly.
Cook the eggs in the air fryer for about 8-10 minutes. At the halfway point, take a spatula and gently stir the eggs to ensure even cooking. Continue cooking until the eggs are set but still slightly creamy.
Once cooked to your desired consistency, remove the basket from the air fryer. Use a spatula to serve the scrambled eggs immediately. Enjoy them on their own, or serve them with toast or as a filling in a breakfast burrito.
