Ingredients for Cottage Cheese & Spinach Crustless Quiche
Main Ingredients
- 6 large eggs
- 1 cup cottage cheese
- 2 cups fresh spinach, chopped
- ½ cup shredded cheddar cheese
- ¼ cup milk
- ¼ cup finely chopped onion
- 1 tablespoon olive oil
- ½ teaspoon garlic powder
- ¼ teaspoon black pepper
- ½ teaspoon salt, or to taste
- ¼ teaspoon paprika
- Cooking spray or butter for greasing
Optional Ingredients
- ½ cup sliced mushrooms
- ¼ cup diced bell pepper
- 2 tablespoons grated Parmesan cheese
- ¼ teaspoon dried oregano
- A pinch of red chili flakes
How to Make Cottage Cheese & Spinach Crustless Quiche
Step 1: Prepare the Oven and Baking Dish
Preheat your oven to 375°F (190°C).
Lightly grease a 9-inch pie dish or an 8-inch square baking dish with cooking spray or butter.
Greasing the dish helps prevent the quiche from sticking and makes it easier to remove clean slices after baking.
Step 2: Cook the Spinach and Onion
Heat the olive oil in a skillet over medium heat.
Add the chopped onion and cook for approximately 3–4 minutes until softened and translucent.
Add the chopped spinach and cook for another 2–3 minutes, stirring occasionally, until wilted.
If using mushrooms or bell peppers, add them with the onion and cook until softened.
Remove the skillet from the heat and allow the vegetables to cool slightly.
Important: If the spinach releases excess water, drain it or gently squeeze out the moisture. This helps prevent a watery quiche.
Step 3: Prepare the Egg Mixture
In a large mixing bowl, crack the eggs and whisk until the yolks and whites are fully combined.
Add the cottage cheese, milk, garlic powder, black pepper, salt, and paprika.
Whisk until everything is evenly incorporated.
The cottage cheese may remain slightly lumpy, which is perfectly fine. These soft curds create a creamy texture throughout the finished quiche.
Step 4: Add the Cheese and Vegetables
Stir the shredded cheddar cheese into the egg mixture.
Add the cooked spinach and onion, mixing gently until evenly distributed.
If using Parmesan cheese, oregano, or chili flakes, add them at this stage.
The mixture should look colorful, creamy, and well combined.
Step 5: Pour Into the Baking Dish
Pour the egg mixture into the prepared baking dish.
Use a spatula to distribute the spinach and cheese evenly.
Sprinkle a little extra shredded cheddar or Parmesan over the top if desired.
Step 6: Bake the Quiche
Place the baking dish in the preheated oven.
Bake for 35–40 minutes, or until the center is set and the top is lightly golden.
To check for doneness, insert a knife into the center. It should come out mostly clean, without liquid egg mixture.
For food safety, the center should reach 160°F (71°C).
If the top browns too quickly, loosely cover the dish with aluminum foil for the remaining baking time.
Step 7: Rest and Serve
Remove the quiche from the oven and allow it to rest for 5–10 minutes.
This resting period helps the eggs finish setting and makes slicing easier.
Cut into six portions and serve warm with fresh herbs, sliced tomatoes, avocado, or a crisp green salad.
Tips for the Best Crustless Quiche
Drain the spinach well: Excess moisture is one of the most common reasons crustless quiche becomes watery.
Use room-temperature eggs: They combine more easily with the cottage cheese and milk.
Don’t overbake: Overcooked eggs can become rubbery. Remove the quiche once the center is set.
Choose your cottage cheese: Full-fat cottage cheese creates a richer texture, while low-fat cottage cheese works well for a lighter version.
Let it rest before slicing: A short resting period helps the quiche hold its shape.
Blend for a smoother texture: If you prefer a smooth filling without visible cottage cheese curds, blend the cottage cheese with the eggs and milk before adding the vegetables.
Delicious Variations
1. Mushroom and Spinach Quiche
Add ½ cup sliced mushrooms to the onion while sautéing. Cook until the mushrooms release their moisture and become tender.
2. Spinach and Feta Quiche
Replace the cheddar cheese with ½ cup crumbled feta cheese.
Feta adds a salty, tangy flavor that pairs beautifully with spinach.
3. High-Protein Crustless Quiche
Use 1½ cups cottage cheese and reduce the milk to 2 tablespoons.
For an additional protein boost, add ½ cup cooked, diced chicken breast.
4. Low-Carb Spinach Quiche
Skip the milk and use full-fat cottage cheese.
Add extra spinach, mushrooms, or bell peppers for more flavor without adding a pastry crust.
5. Mediterranean Crustless Quiche
Add chopped sun-dried tomatoes, black olives, oregano, and feta cheese for a Mediterranean-inspired variation.
What to Serve with Cottage Cheese & Spinach Quiche
This quiche is delicious on its own, but these sides make it an even more satisfying meal:
- Fresh tomato and cucumber salad
- Sliced avocado
- Roasted breakfast potatoes
- Fresh fruit salad
- Whole-grain toast
- Steamed or roasted vegetables
- A simple green salad with lemon dressing
For a balanced breakfast, serve a slice with fresh fruit and a cup of coffee or tea.

Reheating
- Microwave: Heat an individual slice for 30–60 seconds, checking until warmed through.

Frequently Asked Questions
Can I use frozen spinach?
Yes! Thaw the frozen spinach completely and squeeze out as much moisture as possible before adding it to the egg mixture.
Approximately ½ cup of thawed, well-drained spinach can replace the 2 cups of fresh spinach.
Why is my crustless quiche watery?
Excess moisture from spinach, mushrooms, or other vegetables can make the quiche watery.
Cook vegetables before adding them and drain them thoroughly. Avoid adding too much milk.
Can I make this recipe without milk?
Yes. You can omit the milk or replace it with an equal amount of unsweetened almond milk.
The cottage cheese and eggs will still create a creamy filling.
Can I use egg whites instead of whole eggs?
Yes, but the texture will be slightly different. Egg whites generally produce a firmer, less rich quiche.
You may need to adjust the cooking time depending on the amount used.
Is cottage cheese and spinach quiche suitable for a low-carb diet?
Yes. This crustless quiche contains relatively few carbohydrates because it does not use pastry flour.
The exact carbohydrate content depends on the ingredients and serving size.
