Description
This Crustless Vegetable & Spinach Quiche is an easy, satisfying, protein-rich meal that makes a wonderful breakfast, lunch, brunch, or light dinner.

If you are following a Weight Watchers-style eating plan, this recipe can be very low in points and may be 0 points depending on your specific plan and the exact ingredients you use. Always check the ingredients against your current personal WW plan because point values can vary.
One of the best things about this recipe is how flexible it is. You can use the vegetables you already have in your refrigerator, making it an excellent clean-out-the-fridge recipe. Serve a warm slice with fresh fruit, a green salad, or roasted vegetables for a complete and satisfying meal.
Ingredients
• 6 large eggs
• 1 cup liquid egg whites
• 1 cup fresh spinach, chopped
• 1 cup mushrooms, sliced
• ½ cup green onions, sliced
• ½ cup cherry tomatoes, chopped
• ¼ cup finely diced bell pepper
• ¼ cup low-fat or fat-free milk
• ½ teaspoon garlic powder
• ½ teaspoon onion powder
• ½ teaspoon Italian seasoning
• ½ teaspoon salt
• ¼ teaspoon black pepper
• ¼ teaspoon paprika
• Cooking spray
Optional:
• ¼ cup reduced-fat shredded cheese
• Pinch of red pepper flakes
• 2 tablespoons chopped fresh parsley
• 2 tablespoons cooked turkey bacon, finely chopped
Instructions
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly spray a 9-inch or 10-inch pie dish or quiche dish with cooking spray. Make sure the bottom and sides are coated well so the quiche releases easily after baking.
For an especially beautiful presentation, use a round ceramic baking dish similar to the one shown in the photo.
Step 2: Prepare the Vegetables
Wash and dry the spinach thoroughly. Chop it into smaller pieces.
Slice the mushrooms and green onions. Chop the cherry tomatoes and bell pepper into small pieces.
Because vegetables naturally contain water, properly preparing them is important. Mushrooms and spinach can release quite a bit of moisture during cooking, so briefly sautéing them before adding them to the quiche helps prevent a watery center.
Step 3: Cook the Vegetables
Lightly spray a nonstick skillet with cooking spray and place it over medium heat.
Add the mushrooms and cook for approximately 3–4 minutes, stirring occasionally.
Add the chopped spinach and cook for another 1–2 minutes, just until the spinach wilts.
Add the green onions and bell pepper and cook for another minute.
Remove the skillet from the heat and allow the vegetables to cool slightly.
If using tomatoes, you can add them after the vegetables have cooled slightly. This helps retain some of their fresh flavor.
Step 4: Prepare the Egg Mixture
In a large mixing bowl, whisk together the eggs, liquid egg whites, and milk.
Add garlic powder, onion powder, Italian seasoning, salt, black pepper, and paprika.
Whisk until everything is well combined and the mixture looks smooth.
For a little extra flavor, add a pinch of red pepper flakes.
Step 5: Combine Everything
Add the cooked spinach and vegetable mixture to the egg mixture.
Stir gently until the vegetables are evenly distributed.
If you are using reduced-fat cheese, add it now.
You want every slice to contain a nice combination of vegetables and fluffy egg.
Step 6: Pour Into the Baking Dish
Pour the mixture into your prepared pie or quiche dish.
Use a spoon to distribute the vegetables evenly throughout the dish.
Don’t fill the dish all the way to the top because the eggs will expand slightly as they bake.
Step 7: Bake
Place the dish in the center of the preheated oven.
Bake for approximately 30–40 minutes, or until the center is set and the top is lightly golden brown.
The exact cooking time will depend on the size and depth of your baking dish.
To check for doneness, gently shake the dish. The center should have only a slight jiggle rather than looking liquid.
You can also insert a knife into the center. It should come out mostly clean.
Step 8: Rest Before Slicing
Remove the quiche from the oven and allow it to rest for 5–10 minutes before slicing.
This resting period allows the eggs to finish setting and makes it much easier to cut clean, beautiful slices.
Slice into 6 pieces and serve warm.
Notes
This recipe is intentionally crustless, making it much easier than traditional quiche. There is no dough to prepare, roll, chill, or blind-bake.
For the lowest-calorie and lowest-point version, use fat-free milk, cooking spray, and fat-free or reduced-fat ingredients, and skip optional cheese and turkey bacon.
The nutritional information below is an estimate and will change depending on the brands and ingredients you use.
The statement that this is “0 points” should be treated as plan-dependent. WW has different programs and individual ZeroPoint food lists, so check your current WW app or plan for the exact point value.
Tips for the Best Crustless Quiche
Don’t Add Too Much Liquid
Milk helps create a tender texture, but too much liquid can make the quiche watery. Stick close to the amount listed in the recipe.
Cook Moisture-Rich Vegetables First
Spinach and mushrooms release water while cooking. Sautéing them first helps remove some of that moisture and creates a better quiche texture.
Don’t Overbake
Overbaking can make eggs rubbery and dry. Remove the quiche once the center is just set.
Let It Rest
Allowing the quiche to rest for several minutes makes slicing much easier.
Use a Nonstick Dish
A well-greased or sprayed baking dish helps prevent the eggs from sticking to the sides.
Chop Everything Small
Smaller pieces of vegetables distribute more evenly throughout the egg mixture, giving you a little bit of everything in every bite.
Vegetable Substitutions
This recipe is extremely versatile.
You can replace the mushrooms with zucchini, broccoli, asparagus, or cauliflower.
Instead of spinach, try kale, Swiss chard, or another leafy green.
Bell peppers can be replaced with roasted red peppers.
Green onions can be replaced with finely chopped yellow or red onion.
You can also add shredded carrots, cooked broccoli, diced tomatoes, or leftover roasted vegetables.
Just remember that vegetables with a high water content should be cooked or drained before adding them to the egg mixture.
Serving Suggestions
Serve a warm slice of crustless quiche with fresh berries or melon for breakfast.
For lunch, pair it with a simple green salad dressed with lemon juice and a light vinaigrette.
For dinner, serve it with roasted potatoes, steamed vegetables, or a Mediterranean-style cucumber and tomato salad.
It is also delicious with fresh avocado, salsa, Greek yogurt, or a spoonful of cottage cheese.
For brunch, arrange the quiche on a serving platter and garnish with fresh parsley and sliced green onions.
Make-Ahead Instructions
This quiche is excellent for meal preparation.
Bake the entire quiche according to the recipe and allow it to cool completely.
Slice it into 6 portions and place the slices in airtight containers.
Refrigerate for up to 3–4 days.
When ready to eat, reheat individual slices in the microwave for approximately 45–90 seconds, depending on your microwave.
For a better texture, reheat the slices in a toaster oven or conventional oven until warmed through.
Can You Freeze Crustless Quiche?
Yes. Allow the baked quiche to cool completely before freezing.
Wrap individual slices tightly or place them in freezer-safe containers.
Freeze for up to approximately 2 months for best quality.
Thaw overnight in the refrigerator and reheat before serving.
The texture may be slightly different after freezing because vegetables release moisture, but it can still make a convenient make-ahead meal.

Frequently Asked Questions
Is this really a 0-point quiche?
It can be 0 points on some WW plans if all the ingredients used are included in your personal ZeroPoint foods, but WW point calculations depend on the specific plan and ingredients. Always check your current WW app for the most accurate value.
Can I make this quiche without egg whites?
Yes. You can replace the egg whites with additional whole eggs, but this will change the nutritional information and potentially the WW points.
Can I add cheese?
Absolutely. A small amount of reduced-fat cheddar, mozzarella, feta, or Parmesan can add delicious flavor. Remember that adding cheese may change the calorie and WW point value.
Can I use frozen spinach?
Yes. Thaw the spinach completely and squeeze out as much liquid as possible before adding it to the egg mixture.
Why is my crustless quiche watery?
Excess moisture from vegetables is usually the main reason. Sauté spinach and mushrooms first, drain watery vegetables, and avoid adding too much milk.
How do I know when the quiche is done?
The center should be set with only a slight jiggle. A knife inserted into the center should come out mostly clean.
Can I make it dairy-free?
Yes. Use an unsweetened dairy-free milk alternative and skip the cheese.
Can I add meat?
Yes. Cooked turkey sausage, chicken, lean ham, turkey bacon, or cooked shrimp can be added. However, adding meat may change the nutritional information and WW points.
What size dish should I use?
A 9-inch or 10-inch pie dish works well. A deeper dish may require additional baking time.
Can I eat this cold?
Yes. It can be eaten cold or at room temperature, making it convenient for packed lunches. Many people prefer it warmed because the texture becomes softer and more flavorful.
How long does it last in the refrigerator?
Store leftovers in an airtight container in the refrigerator for approximately 3–4 days.
