How to Make Crustless Spinach

Crustless Spinach, Onion & Feta Quiche

Servings: 6
Prep Time: 15 minutes
Cook Time: 35–40 minutes
Total Time: 50–55 minutes

Ingredients:

1 tbsp olive oil or butter

1 medium yellow onion, thinly sliced

2–3 cloves garlic, minced

5 oz fresh spinach (or 10 oz frozen, thawed and squeezed dry)

6 large eggs

1/2 cup whole milk or half-and-half

1/4 tsp salt (adjust to taste)

1/4 tsp black pepper

1/4 tsp nutmeg (optional, but lovely with spinach)

1 cup crumbled feta cheese

1/2 cup shredded mozzarella or cheddar (optional for extra meltiness)

Cooking spray or butter (for greasing the pan)

Instructions:

Preheat Oven:
Preheat to 375°F (190°C). Grease a 9-inch pie dish or round baking dish with cooking spray or butter.

Sauté Onions & Spinach:
Heat olive oil in a skillet over medium heat. Add onions and cook until soft and golden (about 10 minutes). Add garlic and cook 1 more minute.
Stir in fresh spinach and cook until wilted. (If using frozen, just stir it in to warm.)

Whisk Eggs & Seasonings:
In a large bowl, whisk eggs, milk, salt, pepper, and nutmeg.

Assemble Quiche:
Add the cooked onion-spinach mixture to the bottom of the greased dish. Sprinkle feta (and shredded cheese if using) over top. Pour egg mixture evenly over everything.

Bake:
Bake for 35–40 minutes or until the center is just set and slightly golden on top. A knife inserted in the center should come out clean.

Cool & Serve:
Let sit for 5–10 minutes before slicing. Serve warm, room temp, or even cold the next day.

Serving Ideas:

Pair with a light salad or roasted potatoes for a full meal.

Great for brunch, lunch, or meal prep—it reheats beautifully!

Variations:

Add protein: Crumbled bacon, chopped ham, or cooked sausage.

More veggies: Add sautéed mushrooms, bell peppers, or sun-dried tomatoes.

Dairy-free: Use plant-based milk and skip the cheese (or use dairy-free alternatives).
