You don’t need to worry about dough, rolling, or baking time like traditional quiche recipes.

Why Make Crustless Quiche in an Air Fryer?

Using an air fryer saves time and energy. The air fryer heats quickly and cooks evenly, which makes it ideal for egg-based recipes. Unlike the oven, you don’t need to wait long for preheating, and the quiche cooks faster while staying soft inside.

This air fryer egg quiche is:

• Low carb and keto-friendly
• High in protein
• Easy to customize
• Perfect for busy mornings
• Great for meal prep

Because there is no crust, it is also lighter on the stomach and suitable for people avoiding gluten.

Texture and Flavor

The eggs cook gently in the air fryer, giving the quiche a custard-like texture. Milk and cheese add richness, while bell peppers and onions bring a mild sweetness and crunch. The seasoning keeps it balanced without overpowering the eggs.

The center stays soft but fully cooked, and after resting for a few minutes, the quiche firms up just enough to slice or eat directly from the dish.

Ingredient Details (Simple Explanation)

Eggs
Eggs are the base of this recipe. For best results, use eggs that are closer to room temperature. This helps them mix smoothly and cook evenly. Organic or free-range eggs give better flavor, but regular eggs work fine too.

Milk
Milk helps make the quiche soft and fluffy. Whole milk, 2% milk, or even heavy cream can be used. If you prefer a dairy-free option, cashew milk works better than almond milk because it is creamier.

Cheese
Shredded cheese adds flavor and richness. Cheddar cheese works great, and Pepper Jack adds a mild spicy kick. You can also use one type of cheese or mix two together.

Bell Pepper and Onion
Diced bell peppers and onions add color, texture, and natural sweetness. Green bell peppers and yellow onions are a great combination, but other colors work too.

Seasoning
Simple seasoning like salt, pepper, and thyme enhances the taste without overpowering the eggs. You can adjust seasoning based on your preference.

Olive Oil Spray
This prevents sticking and makes it easy to remove the quiche from the dish.

Equipment You’ll Need

A 4-inch oven-safe ceramic dish or springform pan works best for this recipe. It allows easy removal and even cooking. Make sure the dish fits inside your air fryer basket.

Step-by-Step Cooking Overview

First, preheat your air fryer. This step is important because it helps the eggs cook evenly from the start. While the air fryer heats, whisk the eggs in a bowl until smooth. Add milk, cheese, vegetables, and seasonings, then stir until everything is well combined.

Spray your baking dish with olive oil spray to prevent sticking. Pour the egg mixture into the dish and carefully place it in the air fryer basket. Cook until the center is fully set and no longer wet.

Once done, remove the dish and let it rest for a few minutes. This allows the quiche to firm up and makes it easier to eat.

Customization Ideas

This crustless quiche recipe is very flexible. You can:

• Add cooked ham or bacon (must be pre-cooked)
• Add green onions for extra flavor
• Use different cheese blends
• Adjust seasoning to taste

Just remember that any meat should be cooked and drained before adding.

Cooking Frozen Quiche in the Air Fryer (Extra Info)

If you ever cook a frozen quiche in the air fryer, preheat the air fryer to 350°F. Place the frozen quiche directly in the basket and cook until the center reaches 165°F. Cover edges with foil if needed to prevent over-browning and remove foil near the end.

Storage and Reheating

Leftover quiche can be stored in the refrigerator for up to 3 days. Reheat in the air fryer at a low temperature until warmed through. This keeps the texture soft and prevents drying out.
