3. Step-by-Step Cooking Instructions & Crisping Secrets
The key to this omelette is cooking the onion rings in the air fryer at 375°F (190°C) for 5-6 minutes, or until crispy.
This step adds a satisfying crunch and a deep, caramelized flavor.
When cooking the omelette, I like to use a non-stick skillet over medium heat and add the melted butter for a smooth, even cooking process.

Step-by-Step Culinary Timeline
1. Beat eggs in a bowl and set aside.
2. In a separate bowl, mix chopped onion, panko breadcrumbs, grated cheddar cheese, chopped chives, salt, and black pepper.
3. Heat a non-stick skillet over medium heat and add melted butter.
4. Pour in the eggs and cook until the edges start to set, about 2-3 minutes.
5. Add the onion mixture to one half of the omelette and fold the other half over to enclose.
6. Cook for an additional 2-3 minutes, until the cheese is melted and the eggs are cooked through.
Meal-Prep Storage & Crispy Air-Fryer Reheating Guide
• Cool Before Sealing: Let cooked portions cool for 10 minutes before sealing in glass containers so steam never softens the crust (keeps 4 days in the fridge).
• Sauce on the Side: Store dips, drizzles, and fresh herbs separately until right before serving.
• 3-Minute Crispy Reheat: Reheat in a 380°F (193°C) air fryer or dry cast-iron skillet for 3–4 minutes to restore shatteringly crisp edges.
