Spinach, Sun-Dried Tomato & Feta Crustless Quiche

Description

This Spinach, Sun-Dried Tomato & Feta Crustless Quiche is a deliciously savory, protein-rich dish that’s easy enough for a weekday breakfast but elegant enough for a weekend brunch. It combines tender spinach, sweet and tangy sun-dried tomatoes, creamy feta, nutty Parmesan, sautéed onion, garlic, and fragrant oregano in a soft, golden egg custard.

Because there is no crust, this quiche is wonderfully simple to prepare and naturally lighter than a traditional pastry-based quiche. You don’t have to make dough, chill pastry, or worry about a soggy crust. Just sauté the vegetables, whisk together the eggs and dairy, combine everything, and bake until beautifully set.

The feta adds a pleasantly salty and creamy bite, while the sun-dried tomatoes bring concentrated tomato flavor and a subtle sweetness. Garlic and oregano give the quiche a Mediterranean-inspired character that makes every bite flavorful.

This recipe is also incredibly versatile. Serve it warm for breakfast with fresh fruit, enjoy it chilled for lunch with a crisp salad, or cut it into small squares for a brunch buffet. It reheats beautifully, making it an excellent meal-prep option for busy mornings.

Cook Time: 35–40 minutes
Total Time: 50–55 minutes
Servings: 6
Cuisine: Mediterranean-Inspired
Course: Breakfast / Brunch / Lunch
Difficulty: Easy

Ingredients

6 large eggs
1/2 cup milk or heavy cream
2 cups fresh spinach, chopped
1/3 cup sun-dried tomatoes, chopped
3/4 cup crumbled feta cheese
1/4 cup grated Parmesan cheese
1 small onion, finely diced
2 cloves garlic, minced
1 tablespoon olive oil
1 teaspoon dried oregano
1/2 teaspoon salt, or to taste
1/4 teaspoon freshly ground black pepper

Optional Ingredients

1/4 teaspoon red pepper flakes
1/4 teaspoon garlic powder
2 tablespoons fresh parsley, chopped
2 tablespoons fresh basil, chopped
1/2 cup sliced mushrooms
1/2 cup chopped bell pepper
A small handful of shredded mozzarella

Instructions

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C).

Lightly grease a 9-inch pie dish or an 8-inch square baking dish with olive oil or nonstick cooking spray.

If you are using a deeper dish, the quiche may need a few additional minutes of baking time.

Set the prepared dish aside.

Step 2: Prepare the Spinach

Wash the fresh spinach thoroughly and drain it well.

Roughly chop the spinach into smaller pieces.

If your spinach leaves are particularly large, remove any tough stems.

You can also use baby spinach, which requires very little preparation.

Step 3: Sauté the Onion

Heat 1 tablespoon olive oil in a large skillet over medium heat.

Add the finely diced onion and cook for approximately 3–4 minutes, stirring occasionally, until the onion becomes soft and translucent.

Avoid browning the onion too heavily. You want it tender and slightly sweet.

Step 4: Add the Garlic

Add the minced garlic to the skillet.

Cook for approximately 30–60 seconds, stirring constantly.

Garlic cooks quickly, so be careful not to let it burn.

Step 5: Cook the Spinach

Add the chopped spinach to the skillet.

Cook for approximately 2–3 minutes, stirring frequently, until the spinach wilts.

The spinach will shrink dramatically as it cooks.

Once wilted, remove the skillet from the heat.

Allow the mixture to cool for a few minutes.

If there is excess liquid in the skillet, drain it. Removing excess moisture is important because too much water can prevent the quiche from setting properly.

Step 6: Prepare the Sun-Dried Tomatoes

Chop the sun-dried tomatoes into small pieces.

If you are using sun-dried tomatoes packed in oil, drain them first.

If they are particularly oily, gently blot them with a paper towel.

Add the chopped tomatoes to the cooled spinach and onion mixture.

Step 7: Whisk the Eggs

Crack the six eggs into a large mixing bowl.

Add the milk or heavy cream, dried oregano, salt, and black pepper.

Whisk thoroughly until the eggs and dairy are completely combined.

For an especially smooth custard, whisk for about 30–45 seconds.

If using red pepper flakes, add them at this stage.

Step 8: Add the Cheese

Add the crumbled feta and grated Parmesan to the egg mixture.

Stir gently to distribute the cheeses evenly.

Remember that feta and Parmesan are both naturally salty, so be conservative with additional salt.

Step 9: Combine Everything

Add the sautéed spinach, onion, garlic, and sun-dried tomatoes to the egg mixture.

Stir gently until all of the ingredients are evenly distributed.

Make sure the vegetables are not clumped together in one area.

Step 10: Fill the Baking Dish

Pour the mixture into the prepared baking dish.

Use a spatula to distribute the spinach, sun-dried tomatoes, and cheese evenly throughout the dish.

If desired, sprinkle a small amount of additional feta or Parmesan over the top.

Step 11: Bake

Place the quiche in the preheated oven.

Bake for approximately 35–40 minutes, or until the center is set and the top is lightly golden.

The center may have a very slight jiggle when you first remove it from the oven, but it should not look liquid.

Avoid overbaking because this can make the eggs rubbery or dry.

Step 12: Rest Before Serving

Remove the quiche from the oven and allow it to rest for 5–10 minutes before slicing.

This allows the egg custard to finish setting and makes the slices easier to serve.

Garnish with fresh parsley or basil if desired.

Slice into wedges and serve warm.

Notes

The most important step for a successful crustless quiche is controlling moisture.

Spinach contains a lot of water, so cooking and draining it before adding it to the eggs helps prevent a watery quiche.

Sun-dried tomatoes packed in oil should also be drained before chopping.

Heavy cream creates a richer, more luxurious custard, while milk creates a lighter texture.

You can use baby spinach or mature spinach. Both work well.

Because feta and Parmesan already provide plenty of salt, taste your ingredients before adding additional salt.

Tips for the Best Crustless Quiche

Remove Excess Moisture

Cook the spinach until wilted, then drain away any excess liquid. This helps the quiche remain firm and creamy.

Don’t Overbake

The quiche will continue cooking slightly from residual heat after it comes out of the oven. Remove it when the center is just set.

Use Room-Temperature Eggs

Room-temperature eggs combine more easily with the milk and create a more even custard.

Crumble the Feta

Small feta crumbles distribute more evenly throughout the quiche, giving you a little salty, creamy flavor in nearly every bite.

Let It Rest

Cutting the quiche immediately can cause the slices to fall apart. A short resting period helps everything set.

Use a Well-Greased Dish

Because there is no crust, the egg mixture can stick to the baking dish. Grease the dish thoroughly before adding the filling.

Serving Suggestions

This quiche can be served for breakfast, brunch, lunch, or even a light dinner.

Serve it with:

Fresh fruit
Mixed green salad
Greek salad
Cucumber and tomato salad
Roasted potatoes
Avocado slices
Fresh berries
Whole-grain toast
Roasted vegetables
Fresh herbs

For a Mediterranean-inspired brunch, serve a slice with cucumber, tomatoes, olives, fresh fruit, and a small side salad.

For lunch, pair it with a simple green salad dressed with lemon juice and olive oil.

Recipe Variations

Mushroom Spinach Quiche

Sauté 1/2 cup sliced mushrooms with the onion before adding the spinach. Mushrooms add an earthy flavor and meaty texture.

Spinach and Mushroom Feta Quiche

Combine mushrooms with the original recipe for an even more vegetable-packed version.

Spicy Mediterranean Quiche

Add 1/4 teaspoon red pepper flakes or a pinch of cayenne pepper.

Tomato Basil Quiche

Replace some of the oregano with fresh basil and add extra sun-dried tomatoes for a stronger tomato flavor.

Pepper and Spinach Quiche

Add 1/2 cup diced red or yellow bell pepper to the sautéed vegetables.

Extra-Cheesy Version

Add 1/2 cup shredded mozzarella along with the feta and Parmesan.

Lower-Fat Version

Use low-fat milk and reduced-fat feta. The resulting quiche will be lighter while remaining flavorful.

Herb-Rich Version

Add fresh parsley, basil, dill, or chives to the egg mixture before baking.

Frequently Asked Questions

Can I use frozen spinach?

Yes. Frozen spinach works very well, but thaw it completely and squeeze out as much excess moisture as possible before adding it to the egg mixture.

Can I use regular tomatoes instead of sun-dried tomatoes?

Yes, but fresh tomatoes contain considerably more water. If using them, remove some of the seeds and excess moisture and sauté them briefly before adding them.

Can I use heavy cream instead of milk?

Absolutely. Heavy cream creates a richer, creamier quiche. Milk creates a lighter custard.

Can I use a different cheese?

Yes. Goat cheese, mozzarella, cheddar, Swiss cheese, or ricotta can be used. Feta provides the strongest Mediterranean flavor.

Why is my crustless quiche watery?

Excess moisture from spinach, tomatoes, or other vegetables is usually the main reason. Cook watery vegetables first and drain them thoroughly.

Why did my quiche become rubbery?

Overbaking is the most common reason. Remove the quiche when the center is just set and allow it to rest before slicing.

Can I add meat?

Yes. Cooked turkey sausage, chicken, bacon, ham, or diced cooked chicken can be added. Make sure any meat is fully cooked before combining it with the eggs.

Can I make this vegetarian?

Yes. The recipe as written is vegetarian.

Can I make it gluten-free?

Yes. The recipe is naturally crustless and contains no flour. Check packaged ingredients such as seasonings and sun-dried tomatoes if you need strict gluten-free preparation.

Can I make individual mini quiches?

Yes. Divide the mixture between greased muffin cups and bake until the centers are set. The cooking time will be significantly shorter, so begin checking them around 18–22 minutes.

Can I prepare this the night before?

Yes. Bake it the evening before, refrigerate it after cooling, and reheat it the next morning.

Can I eat this quiche cold?

Yes. It tastes delicious chilled and can be especially convenient for packed lunches.

How do I know when it is done?

The edges should be set, the top should be lightly golden, and the center should have only a slight jiggle rather than appearing liquid.

Can I add more vegetables?

Absolutely. Mushrooms, bell peppers, zucchini, broccoli, asparagus, and roasted red peppers can all work well. Cook vegetables that release a lot of moisture before adding them.
