Air Fryer Sausage and Egg Breakfast Casserole

A quick, low-carb, and keto-friendly breakfast casserole made in the air fryer for easy cleanup and customizable flavors.

Ingredients

• 8 large eggs
• 1/2 cup heavy cream (or whole milk)
• 8 oz breakfast sausage (cooked and crumbled)
• 1 cup shredded cheddar cheese (divided)
• 1/4 cup diced bell peppers (optional, for color and crunch)
• 2 tablespoons fresh chives (finely chopped, plus extra for garnish)
• 1/2 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1/2 teaspoon salt
• 1/4 teaspoon freshly ground black pepper

Instructions

1. Preheat your air fryer to 350°F (175°C) for about 3 to 5 minutes. Lightly grease a 6-inch or 7-inch round cake pan or air-fryer-safe baking dish with cooking spray or butter.
2. If using raw breakfast sausage, cook it in a skillet over medium-high heat, breaking it apart until thoroughly browned and cooked through (about 5-7 minutes). Drain excess grease and let it cool slightly.
3. In a large mixing bowl, whisk 8 large eggs and heavy cream until smooth and well-combined. Add garlic powder, onion powder, salt, and black pepper, whisking once more.
4. Add the cooked sausage, three-quarters of the shredded cheddar cheese, diced bell peppers, and chopped chives to the egg mixture. Stir gently with a spatula to ensure even distribution.
5. Pour the mixture into the prepared greased baking dish. Tap the dish gently on the counter to release any trapped air bubbles.
6. Place the baking dish into the preheated air fryer basket. Cook at 350°F (175°C) for 20 minutes.
7. Open the air fryer and sprinkle the remaining cheddar cheese evenly across the top. Cook for an additional 3 to 5 minutes, or until the cheese is melted, bubbly, and golden-brown, and the center is set.
8. Remove the dish carefully using heat-resistant mitts. Allow the casserole to rest for 5 minutes to set. Garnish with remaining fresh chives, slice into wedges, and serve warm.

Notes

Ensure the baking dish fits in the air fryer basket with a small gap for air circulation. Check the casserole around the 20-minute mark to avoid overcooking. You can substitute sausage with crumbled bacon, diced ham, or chorizo.
