Step 3: Add the cooked sausage, vegetables, potatoes, and shredded cheese to the egg mixture. Stir until well combined.
Step 4: Set your Ninja Crispi to the bake/air crisp function at 350°F. Lightly grease the basket or use parchment paper.

Ninja Crispi Easy Breakfast Casserole Recipe Tips
- Evenly dice ingredients: Small, uniform pieces of potatoes and vegetables ensure even cooking.
- Cook sausage first: Browning the sausage beforehand adds flavor and prevents excess grease.
- Use a little grease: Lightly spray or brush the Ninja Crispi basket to prevent sticking.
- Check doneness early: Air fryer models vary—start checking at 18-20 minutes.
- Customize freely: Swap in bacon, ham, spinach, mushrooms, or your favorite cheeses.
Storing Instructions
- Refrigerator: Store leftover casserole in an airtight container for up to 4 days.
- Reheating: Reheat slices in the air fryer at 320°F for 3–5 minutes or in the microwave until warm.
- Freezing: Wrap individual slices in plastic wrap and foil, freeze up to 2 months. Thaw in the fridge before reheating.
