Step-by-Step Instructions

Cooking sausage and prepping spinach for air fryer quiche

1) Prep the fillings

Cook sausage links in the air fryer for 3 minutes at 350°F (175°C). Flip or stir and cook 3 more minutes at 370°F (185°C). While sausage cooks, steam spinach with a splash of water in a covered bowl in the microwave for about 2 minutes; squeeze out excess liquid.

3) Assemble & air fry

Lightly spray your 6–7″ pan. Layer in sausage, then spinach, then cheese. Pour egg mixture over the top. Air fry at 350°F (175°C) for 12–16 minutes until the center is just set and a toothpick comes out mostly clean. Rest 3–5 minutes to finish setting for cleaner slices.

Mini portions: Use silicone muffin cups or ramekins to make individual servings. For timing, see our Air Fryer Egg Bites guide.

How Long to Cook a Crustless Quiche in the Air Fryer

Cook time for air fryer crustless quiche depends on pan size, filling volume, and your air fryer model. Start checking the quiche at around 12 minutes.

FAQ

Can I add a crust to this crustless quiche?

Yes—blind bake a small ready-made crust separately until lightly golden, then fill and air fry at 330–340°F so the crust doesn’t over-brown. Timing will be a bit longer; watch for set center.

What’s the best cheese to make crustless quiche?

Cheddar for melty richness, feta for tang, Parmesan for umami. A blend gives the best flavor and texture.

Why did my quiche turn watery?

Tips to help with watery quiche: Squeeze excess moisture from veggies beforehand (like spinach or tomatoes) and avoid over-measuring milk/cream. Let the quiche rest 3–5 minutes before cutting in order for it to firm up.

Can I make air fryer crustless quiche dairy-free?

Yes—use an unsweetened non-dairy milk and skip cheese or use a meltable dairy-free cheese.
