Spinach and Cheese Crustless Quiche
Spinach and Cheese Crustless Quiche is a simple, protein-packed dish that works perfectly for breakfast, brunch, lunch, or even a light dinner.

Ingredients
Core Ingredients
5 to 8 large eggs
10 oz frozen chopped spinach, thawed and squeezed dry
or 6–10 oz fresh baby spinach
2 to 3 cups shredded cheese
(Muenster, Gruyère, sharp cheddar, mozzarella, or a blend)
1 medium onion, diced
2 garlic cloves, minced
½ to 1 cup milk or heavy cream
(optional for a softer custard texture)
1 tablespoon olive oil or butter
¼ teaspoon salt
¼ teaspoon black pepper
Pinch of ground nutmeg
Optional: ½ cup cottage cheese for extra protein and creaminess
Instructions
Prepare the Oven and Baking Dish
Preheat your oven to 375°F (190°C). Lightly grease a 9-inch pie dish or baking dish with butter or cooking spray to prevent sticking.
Cook the Aromatics
Heat olive oil or butter in a skillet over medium heat. Add the diced onion and sauté for 4–5 minutes until softened and lightly golden.
Add the minced garlic and cook for another 30 seconds until fragrant.
Prepare the Spinach
If using frozen spinach, make sure it is completely thawed and squeezed dry. Removing excess moisture is important so the quiche does not become watery.
If using fresh spinach, cook it briefly in the skillet until wilted, then let it cool slightly.
Mix the Egg Filling
In a large mixing bowl, whisk together the eggs, milk or cream, salt, black pepper, and nutmeg until smooth.
Stir in the shredded cheese and optional cottage cheese.
Fold in the cooked onions, garlic, and spinach mixture.
Assemble the Quiche
Pour the mixture into the prepared baking dish and spread evenly.
You can sprinkle a little extra cheese on top for a golden cheesy crust.
Bake
Bake for 40–45 minutes or until the center is set and the top is lightly golden.
A knife inserted in the middle should come out mostly clean.
Cool and Serve
Allow the quiche to cool for 5–10 minutes before slicing. This helps it firm up and makes serving easier.
Serve warm with salad, toast, roasted potatoes, or fresh fruit.
Tips
Squeeze Spinach Thoroughly
Excess moisture is the biggest reason crustless quiche turns watery. Press frozen spinach with paper towels or a clean kitchen towel until very dry.
Use Full-Fat Cheese for Best Flavor
Cheeses like Gruyère, cheddar, or Muenster melt beautifully and create a richer texture.
Don’t Overbake
The quiche should still have a slight jiggle in the center when removed from the oven. It continues cooking as it cools.
Room Temperature Eggs Mix Better
Let eggs sit out for 10–15 minutes before whisking for a smoother filling.
Add Cheese in Layers
For extra cheesy texture, mix some cheese into the filling and sprinkle the rest on top.
Use Heavy Cream for Richness
Heavy cream creates a softer, silkier texture, while milk keeps the dish lighter.
Let It Rest Before Cutting
Cooling slightly helps the slices hold together neatly.
Season Carefully
Different cheeses contain different salt levels, so taste your mixture before adding extra salt.
Make It Ahead
This quiche stores well in the refrigerator for up to 4 days and reheats perfectly.
Freeze for Meal Prep
Slice the cooled quiche and freeze individual portions for quick breakfasts.
Variations
Mushroom Spinach Quiche
Add sautéed mushrooms for an earthy flavor and heartier texture.
Mediterranean Style
Mix in feta cheese, olives, and sun-dried tomatoes for a Mediterranean twist.
High-Protein Version
Add cottage cheese or cooked turkey sausage for extra protein.
Spicy Version
Include red pepper flakes, jalapeños, or pepper jack cheese for heat.
Low-Dairy Option
Use reduced cheese and unsweetened almond milk instead of cream.
Crusty Topping
Sprinkle breadcrumbs and Parmesan on top for a crispy finish.
Herb-Loaded Quiche
Add fresh dill, parsley, basil, or chives for extra freshness.
Broccoli and Spinach Combo
Mix chopped steamed broccoli with spinach for added vegetables.
Bacon and Cheddar
Crispy bacon and sharp cheddar make the quiche richer and smokier.
Mini Quiches
Pour the mixture into muffin tins for portable individual servings.
