Air Fryer Crustless Spinach & Tomato Quiche

Air Fryer Crustless Spinach & Tomato Quiche is a quick, savory egg dish filled with fresh spinach, juicy tomatoes, onion, and melted cheese. Because it skips the traditional pastry crust, preparation stays simple while the eggs and vegetables remain the focus.

The air fryer also makes this recipe especially convenient. After a short preheat, the quiche cooks in about 15 to 20 minutes in a small air fryer-safe baking dish. Then a brief resting period helps the eggs settle before slicing.

Air Fryer Crustless Spinach & Tomato Quiche works for breakfast, brunch, lunch, or a light dinner. You can serve it warm on its own or add fruit, toast, or a simple salad for a more complete meal.

I like recipes like this when I want something more substantial than scrambled eggs but don’t want to prepare a pastry crust. The combination of spinach and tomatoes keeps every slice colorful, while the cheese gives the eggs a richer texture. I also appreciate that everything gets mixed in one bowl before going into the air fryer. The only part I watch carefully is the final few minutes because different air fryers can cook at noticeably different speeds. Once the center looks set, I give the quiche five minutes to rest. That short wait makes it much easier to cut into neat wedges.

Preparing the Egg and Vegetable Mixture

Whisk the Eggs and Milk

Start by preheating the air fryer to 320°F for approximately 3 minutes.

Meanwhile, crack 6 large eggs into a mixing bowl.

Add ¼ cup milk.

Whisk the eggs and milk together until the mixture becomes smooth and evenly combined.

A thorough whisk helps distribute the yolks, whites, and milk throughout the Air Fryer Crustless Spinach & Tomato Quiche.

Next, prepare a small air fryer-safe baking dish or cake pan that fits comfortably inside your air fryer basket.

Line the dish with parchment paper if desired. Make sure the pan and egg mixture hold the parchment securely in place.

Add the Vegetables and Cheese

Roughly chop 1 cup fresh spinach.

Next, dice ½ cup cherry tomatoes and ¼ cup onion.

Add the spinach, tomatoes, and onion directly to the whisked egg mixture.

Then stir in ¾ cup shredded cheddar or mozzarella cheese.

Cheddar provides a stronger cheese flavor, while mozzarella creates a milder result. Either option works well.

Season the mixture with ½ teaspoon garlic powder, ¼ teaspoon salt, and ¼ teaspoon black pepper.

Stir gently until the vegetables, cheese, and seasonings become evenly distributed.

The colorful mixture now contains everything needed for the main body of the quiche.

Preparing the Quiche for the Air Fryer

Fill the Baking Dish

Carefully pour the egg and vegetable mixture into the prepared air fryer-safe baking dish.

Use a spoon to distribute the spinach, tomatoes, and onions evenly if they collect in one area.

If desired, sprinkle 1 tablespoon grated Parmesan cheese over the top.

The Parmesan adds another layer of savory cheese flavor and creates a lightly golden finish as the Air Fryer Crustless Spinach & Tomato Quiche cooks.

Don’t overfill the baking dish. The egg mixture needs enough room to cook and expand slightly without spilling.

Place the Dish in the Air Fryer

Carefully transfer the filled baking dish into the preheated air fryer basket.

Make sure the pan sits level before beginning the cooking cycle.

Set the air fryer to 320°F.

The relatively moderate temperature gives the center of the egg mixture time to cook before the surface becomes too dark.

Additionally, avoid opening the air fryer repeatedly during the first part of cooking.

Instead, begin checking the quiche a few minutes before the expected finishing time, particularly if you know your air fryer tends to cook quickly.

Air Frying Until the Quiche Is Set

Cook for 15 to 20 Minutes

Air fry the quiche at 320°F for approximately 15 to 20 minutes.

The exact cooking time depends on your air fryer, the dimensions of your baking dish, and the depth of the egg mixture.

Therefore, start checking toward the early end of the cooking range.

The center should look set rather than liquid.

Additionally, the egg mixture should reach 160°F in the center.

If necessary, continue cooking for a few additional minutes while monitoring the top.

Prevent Excessive Browning

Some air fryers produce stronger heat at the top than others.

Consequently, the surface of the Air Fryer Crustless Spinach & Tomato Quiche may brown before the center has completely finished cooking.

If that happens, loosely cover the baking dish with foil and continue air frying.

Make sure the foil remains properly secured and does not interfere with the air fryer’s heating element.

Continue cooking until the center has set.

Once ready, carefully remove the hot baking dish from the basket and place it on a heat-safe surface.

The quiche will continue settling slightly as it rests.

Resting and Serving Air Fryer Crustless Spinach & Tomato Quiche

Rest Before Slicing

Allow the finished quiche to rest for approximately 5 minutes.

Although it may be tempting to cut it immediately, this short resting period makes slicing much easier.

The eggs settle as they cool slightly, helping the wedges maintain their shape.

After 5 minutes, carefully loosen the edges if necessary.

Then cut the Air Fryer Crustless Spinach & Tomato Quiche into four portions.

Each slice should contain visible spinach, tomato, onion, and melted cheese throughout the egg base.

Serve It for Breakfast or Brunch

Serve the quiche while it’s pleasantly warm.

For breakfast, pair it with fresh fruit or toast. For brunch, you can add roasted potatoes or a simple green salad.

Because this quiche already contains eggs, vegetables, and cheese, it can also stand alone as a light meal.

The absence of a pastry crust keeps preparation straightforward while allowing the vegetables and cheese to remain prominent.

With only a few minutes of preparation, about 15 to 20 minutes of air frying, and a short resting period, Air Fryer Crustless Spinach & Tomato Quiche provides an easy way to turn everyday ingredients into a warm and satisfying meal.
