Ingredients
- 6 large eggs
- 1/2 cup milk or heavy cream
- 2 cups fresh spinach, chopped
- 1/2 cup sun-dried tomatoes, chopped
- 3/4 cup crumbled feta cheese
- 1/2 cup shredded mozzarella cheese
- 1 small onion, finely diced
- 2 cloves garlic, minced
- 1 tablespoon olive oil

How to Make Spinach, Sun-Dried Tomato & Feta Crustless Quiche
1. Prepare the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9-inch pie dish or similar baking dish with olive oil or cooking spray. Greasing the dish makes it easier to remove the slices once the quiche has cooled.
2. Sauté the Aromatics
Heat the olive oil in a skillet over medium heat.
Add the finely diced onion and cook for about 2 to 3 minutes, stirring occasionally, until it begins to soften.
Add the minced garlic and cook for another 30 seconds to 1 minute. Be careful not to let the garlic burn because it can become bitter.
3. Cook the Spinach
Add the chopped spinach to the skillet.
At first, the pan may look very full, but spinach wilts quickly. Stir it regularly and cook until the leaves are tender and most of their moisture has evaporated.
Remove the skillet from the heat and allow the mixture to cool slightly.
This step is important because excess moisture can make a crustless quiche watery.
4. Prepare the Egg Mixture
Crack the eggs into a large mixing bowl.
Add the milk or heavy cream, dried oregano, black pepper, and a small amount of salt. Whisk everything together until the eggs are smooth and the mixture is evenly combined.
Be cautious with the salt because feta cheese and sun-dried tomatoes can already be quite salty.
5. Add the Filling
Add the cooked spinach and onion mixture to the eggs.
Stir in the chopped sun-dried tomatoes, crumbled feta, and shredded mozzarella.
Gently mix everything together until the vegetables and cheese are evenly distributed.
6. Fill the Baking Dish
Pour the egg mixture into your prepared pie dish.
Use a spatula to spread the ingredients evenly if necessary. Make sure the spinach, tomatoes, and cheese aren’t concentrated in one area.
7. Bake
Place the dish in the preheated oven and bake for approximately 30 to 35 minutes.
The quiche is ready when the center is set and the top is lightly golden.
A slight jiggle in the very center can be okay because the eggs will continue to set as the quiche cools. Avoid overbaking, as this can make the eggs rubbery.
8. Rest Before Serving
Remove the quiche from the oven and let it rest for 5 to 10 minutes before slicing.
This short resting period allows the filling to finish setting and makes it much easier to cut clean, attractive slices.
Garnish with a little fresh parsley or extra feta if desired.
Helpful Tips for the Best Quiche
Remove Excess Moisture
Vegetables contain water, and too much moisture can prevent a crustless quiche from setting properly. Cook the spinach until wilted and allow excess liquid to evaporate.
If you’re using frozen spinach, thaw it completely and squeeze out as much water as possible before adding it.
Don’t Overbake
The goal is a tender, fluffy texture. Once the center has set, take the quiche out of the oven. Overcooking can cause the eggs to become firm and rubbery.
Season Carefully
Feta and sun-dried tomatoes can both add plenty of salt. Taste your vegetable mixture if appropriate and use salt conservatively in the egg mixture.
Let It Rest
Cutting into the quiche immediately can cause the slices to fall apart. Giving it several minutes to rest makes serving much easier.
Easy Variations
One of the best things about a crustless quiche is how easy it is to customize.
For a vegetable-packed version, add sliced mushrooms, diced bell peppers, zucchini, or broccoli. Sauté vegetables first to remove excess moisture.
For extra Mediterranean flavor, replace the oregano with a Greek seasoning blend. You can also add a handful of chopped fresh parsley or basil.
If you enjoy stronger cheese, replace some of the mozzarella with shredded cheddar, Parmesan, or Monterey Jack.
For a little heat, add red pepper flakes or finely diced jalapeño.
You can also add cooked chicken, turkey, or another protein if you want to make the quiche more substantial.
What to Serve With Crustless Quiche
This quiche is satisfying on its own, but a few simple sides can turn it into a complete meal.
For breakfast or brunch, serve slices with fresh fruit, roasted potatoes, or a simple green salad.
For lunch, pair it with cucumber and tomato salad, soup, or roasted vegetables.
A little fresh avocado on the side is another delicious option.
Because the quiche tastes excellent warm or chilled, it’s also ideal for packed lunches and meal-prep containers.

Frequently Asked Questions
Can I make this quiche ahead of time?
Absolutely. Bake it up to 4 days ahead and keep it refrigerated in an airtight container. Reheat individual portions when you’re ready to serve.
Can I use frozen spinach?
Yes. Thaw the spinach completely and squeeze it very well to remove excess water before adding it to the recipe.
Is this crustless quiche keto-friendly?
It can fit into many low-carb eating patterns because it doesn’t contain a traditional flour-based crust. However, the exact carbohydrate content depends on the ingredients and portion size, so check the nutrition information for your specific products if you follow a strict ketogenic diet.
Can I use a different cheese?
Definitely. Feta provides a distinctive salty flavor, but you can replace some of it with cheddar, Parmesan, Swiss, or another cheese you enjoy.
Why is my quiche watery?
Excess moisture from spinach or other vegetables is usually the main reason. Cook fresh vegetables before adding them and thoroughly squeeze thawed frozen spinach.
Can I make this without heavy cream?
Yes. Regular milk works well and produces a slightly lighter texture. Heavy cream creates a richer, creamier quiche.
