Description

This easy air fryer breakfast casserole bakes fluffy eggs, savory sausage, and melty cheddar into individual ramekins in about 20 minutes. It's keto-friendly, make-ahead friendly, and endlessly customizable — the perfect fast, hot breakfast for busy mornings.

Ingredients 

  • 4 large eggs
  • 2 tablespoons heavy cream
  • 1 pound Italian sausage, cooked and drained
  • 1 cup diced tomatoes and green chilies, drained
  • 1/2 cup cheddar cheese, shredded (plus extra for topping)
  • 2 teaspoons Italian seasoning
  • Salt and pepper, to taste

Instructions

  • In a large bowl, stir together the cooked sausage, drained diced tomatoes and green chilies, and Italian seasoning until well combined. Fold in most of the shredded cheddar, reserving a little for topping.
  • Add the eggs and heavy cream, then whisk until the mixture is slightly frothy.
  • Lightly grease your ramekins (or line the basket with a silicone mold/parchment). Divide the mixture evenly and top each with the reserved cheese.
  • Air fry at 340°F for 5–8 minutes, until the centers are fully set and the cheese is melted and bubbly. Air fryers vary, so check at 5 minutes.
  • Let rest 2–3 minutes, then serve warm.

Equipment

Notes

  • Watery casserole? Drain the tomatoes and any thawed veggies well, and pre-cook watery vegetables.
  • Ramekin size: 6 oz or 8 oz both work; add 1–2 minutes for larger ramekins.
  • Make ahead: Mix the night before and refrigerate; cook fresh in the morning.
  • Storage: Fridge up to 3 days; freezer up to 2 months. Reheat in the air fryer at 320°F for 2–3 minutes.
  • Keto: Use almond milk instead of cream and skip the tomatoes.
