Description

A creamy, protein-packed crustless quiche bursting with tender spinach, tangy feta, and flavorful sautéed garlic and onion. Baked to a golden finish, the Crustless Spinach and Feta Quiche is a  versatile, low‑carb dish that makes a bright Mediterranean-style breakfast, brunch, or light lunch—delicious served warm, room‑temperature, or chilled.


Ingredients

  • 5 large eggs
  • 1 cup whole milk (or ¾ cup milk + ¼ cup cream)
  • 1½ cups fresh spinach (sautéed and drained) or ¾ cup frozen spinach (thawed and drained)
  • ¾ cup crumbled feta cheese
  • ½ small onion, diced
  • 1 garlic clove, minced
  • ½ tsp salt
  • ¼ tsp black pepper
  • 1 tbsp olive oil (for sautéing)
  • Optional: pinch of nutmeg or chopped herbs like dill

Instructions

1. Prepare & Preheat

Preheat oven to 350°F (175°C) (some recipes use 375°F/190°C—either works).

Grease a 9-inch pie dish with butter, olive oil, or non-stick spray.

2. Sauté the Veggies

Heat 1 tbsp olive oil (or butter) in a skillet over medium heat.
Add ½ small diced onion and sauté until soft (about 3–4 minutes).
Stir in 1 minced garlic clove, cooking for about 1 more minute until fragrant.
Add 1½ cups fresh spinach (or ¾ cup thawed, drained frozen spinach) and cook until wilted. For frozen spinach, be sure to thoroughly squeeze out excess moisture.

3. Whisk the Custard

In a bowl, whisk together:
5 large eggs
1 cup whole milk (or ¾ cup milk + ¼ cup cream)
½ tsp salt, ¼ tsp pepper
Optional: pinch of nutmeg (for warmth/flavor)

4. Combine & Assemble

Place sautéed spinach-onion-garlic mixture into the greased pie dish.

Sprinkle ¾ cup crumbled feta cheese over the top

Pour the egg-milk mixture evenly over the vegetables and feta. Gently stir to distribute ingredients.

5. Bake the Quiche

Bake on the middle oven rack for 35–45 minutes, or until: 

  • The custard is just set (firm edges, slightly jiggly center).

  •  A knife inserted in the center comes out clean.

  • Tip: If using temperatures on the lower end (350°F), expect around 45–50 minutes; if at 375°F, aim for 35–40 minutes.

6. Rest & Serve

Remove from oven and let rest for 5–10 minutes before cutting to ensure clean slices.

Serve warm, at room temperature, or even chilled—it’s delicious any way you enjoy it!

Notes

1. Prevent Watery Quiche

Drain thoroughly: Whether you use fresh or frozen spinach, sauté first and squeeze out excess moisture—this step is crucial to avoid a soggy quiche.

Cook add-ins fully: Onions and garlic should be cooked until soft, and water-heavy ingredients like mushrooms or zucchini must be sautéed until just dry .

2. Customize Flavor & Texture

Cheese variations: Substitute some feta with goat cheese, ricotta, Parmesan, or mozzarella for different textures and richer flavor profiles .

Add-ins: Try stirring in sun-dried tomatoes, kalamata olives, mushrooms, chorizo, bacon, smoked salmon, or fresh herbs (dill, parsley, tarragon) to enhance taste and protein.

3. Make-Ahead & Storage

Prep in advance: Bake ahead, chill, then slice and reheat for a quick breakfast or lunch .

Fridge storage: Keeps well in the fridge for 3–5 days; reheat gently or serve cold

Freezing option: Freeze whole or in slices (wrapped) for up to 3 months, then thaw before reheating

4. Cooking Tips

Pan warmth: Preheat your pie dish or skillet to ensure even baking and cleaner edges—some experts even lightly butter the pan and sprinkle Parmesan at the base for extra flavor .

Bake temperature/time: 350°F is standard for 35–45 minutes; if using 375°F, aim for 35–40 min. Adjust based on your oven—cook on center rack for best results .

5. Serving Suggestions

Garnish: Sprinkle with fresh herbs, cherry tomatoes, sliced avocado, or extra crumbled feta for a fresh finish.
Pairings: Serve with a crisp salad (e.g., Greek or Shopska) or roasted breakfast potatoes for a complete and satisfying meal .
