Instructions

1. Preheat the Oven

Preheat your oven to 375°F (190°C).

Lightly coat a 9-inch pie dish or similar baking dish with cooking spray.

For easier cleanup, you can also line the bottom with parchment paper.

2. Prepare the Vegetables

Wash and dry the spinach thoroughly.

Slice the mushrooms and dice the bell pepper and red onion.

Heat a large nonstick skillet over medium heat and lightly coat it with cooking spray.

Add the mushrooms and onion.

Cook for approximately 4–5 minutes, stirring occasionally, until the mushrooms release their moisture and begin to soften.

Add the bell pepper and garlic.

Cook for another 1–2 minutes.

Finally, add the spinach and cook just until wilted, about 1–2 minutes.

Remove the skillet from the heat and allow the vegetables to cool slightly.

Important Tip

Don’t skip cooking the mushrooms and spinach first. These vegetables contain a lot of moisture, and removing some of that moisture helps prevent a watery quiche.

3. Prepare the Egg Mixture

In a large mixing bowl, whisk together the eggs, egg whites, and fat-free Greek yoghurt.

Whisk until the mixture is smooth and well combined.

Add:

• Italian seasoning
• Garlic powder
• Paprika
• Black pepper
• Salt
• Fresh parsley
• Basil

Whisk again.

The Greek yoghurt gives the quiche a creamy texture while adding extra protein.

4. Combine the Vegetables and Eggs

Add the sautéed vegetables to the egg mixture.

Stir gently until the spinach, mushrooms, peppers, and onions are evenly distributed.

Taste the mixture before baking and adjust the seasoning if necessary.

5. Pour Into the Baking Dish

Pour the mixture into the prepared pie dish.

Use a spatula to distribute the vegetables evenly.

If desired, sprinkle a little extra parsley or basil over the top.

6. Bake

Place the dish in the preheated oven.

Bake for approximately 35–45 minutes, or until:

• The centre is set.
• The edges are lightly golden.
• The top is puffed and lightly browned.
• A knife inserted near the centre comes out mostly clean.

Avoid overbaking because this can make the eggs rubbery or dry.

7. Let It Rest

Remove the quiche from the oven and let it rest for approximately 10 minutes before slicing.

The centre will continue to settle slightly as it cools.

Slice into wedges and serve warm.

You can garnish with fresh parsley, basil, sliced green onions, or freshly cracked black pepper.

Benefits of Crustless Zero-Point Vegetable Quiche

1. High in Protein

Eggs, egg whites, and Greek yoghurt provide a substantial amount of protein in every serving.

Protein can help make breakfast more satisfying and contributes to maintaining muscle.

2. Loaded With Vegetables

Spinach, mushrooms, peppers, onions, and garlic provide a variety of nutrients and beneficial plant compounds.

3. No Traditional Crust

Skipping the pastry crust makes this quiche lighter and eliminates the need for flour-based dough.

4. Meal-Prep Friendly

The quiche can be sliced into individual portions and refrigerated for convenient breakfasts throughout the week.

5. Naturally Versatile

You can change the vegetables according to the season or whatever you have in your refrigerator.

6. Filling Without Being Heavy

The combination of protein, vegetables, and eggs creates a satisfying meal without relying on a heavy pastry crust.

Recipe Notes

Don’t Add Raw Watery Vegetables

Vegetables such as mushrooms, spinach, zucchini, and tomatoes contain significant amounts of water.

Cooking them first helps prevent excess moisture from collecting in the finished quiche.

Use Fresh Spinach

Fresh spinach works particularly well because it wilts quickly and blends naturally into the egg mixture.

Frozen spinach can also be used, but thaw it completely and squeeze out as much water as possible.

Greek Yogurt

Use plain, fat-free Greek yoghurt for the lightest version.

Greek yoghurt also helps give the quiche a creamy, tender texture.

Watch the Salt

If you’re using canned or packaged vegetables, check their sodium content before adding additional salt.

Don’t overbake.

The quiche should be just set in the centre. It will continue cooking slightly after being removed from the oven.

Helpful Tips

Tip 1: Use a Nonstick Dish

A well-greased nonstick baking dish makes removing slices much easier.

Tip 2: Let It Cool

Allow the quiche to rest for at least 10 minutes. This makes cleaner slices and improves the texture.

Tip 3: Make Individual Quiches

Divide the mixture among silicone muffin cups and bake for approximately 18–25 minutes, depending on size.

These mini quiches are excellent for meal prep.

Tip 4: Add More Vegetables

Try combinations such as:

Spinach + mushroom + onion

Broccoli + bell pepper + spinach

Zucchini + tomato + basil

Asparagus + mushroom + onion

Tip 5: Add Fresh Herbs

Fresh parsley, basil, dill, chives, or cilantro can dramatically change the flavour without adding much energy.

Tip 6: Add Heat

For a spicy version, add diced jalapeño, red pepper flakes, or a pinch of cayenne.

Meal Prep Instructions

This quiche is excellent for preparing ahead.

Once cooled, slice it into six portions.

Place each portion into an airtight container.

Refrigerate for approximately 3–4 days.

When you’re ready to eat, reheat in the microwave for about 30–60 seconds, depending on your microwave and portion size.

You can also reheat it in a 325°F (165°C) oven until warmed through.

Freezing Instructions

Crustless quiche can be frozen.

Allow the cooked quiche to cool completely.

Slice it into individual portions and wrap each piece tightly or place them in freezer-safe containers.

Freeze for up to approximately 2–3 months for best quality.

Thaw overnight in the refrigerator before reheating.

The texture may be slightly softer after freezing, but it should still be delicious.

Frequently Asked Questions

Is this quiche really zero points?

It may be zero points for some WW members, depending on their current plan and which foods are included in their personal ZeroPoint list. Weight Watchers plans and personalised Points values can change, so it’s best to verify the complete recipe in your current WW app.

Can I make this without Greek yoghurt?

Yes. You can omit the Greek yoghurt, but the quiche will have a slightly different texture and lower protein content.

Can I use all egg whites?

Yes. Using all egg whites creates a lighter quiche and reduces the fat from whole eggs. However, whole eggs provide richness and flavour.

Can I use frozen spinach?

Absolutely. Thaw it completely and squeeze out excess water before adding it to the recipe.

Why is my quiche watery?

The most common reason is excess moisture from vegetables. Sauté mushrooms, spinach, zucchini, or other watery vegetables before adding them to the egg mixture.

Why did my quiche become rubbery?

It was probably baked too long or at too high a temperature. Remove it from the oven as soon as the centre is set.

Can I add cheese?

Yes, cheese can be delicious, but it will change the nutritional information and may affect the points value.

Can I add chicken?

Yes. Add cooked, chopped chicken breast for an even higher-protein meal. Be sure to recalculate the nutrition and points value.

Can I make this dairy-free?

Yes. Replace the Greek yoghurt with an unsweetened dairy-free yoghurt alternative, or omit it and adjust the egg mixture as needed.

Can I make it gluten-free?

Yes. The basic recipe contains no flour or traditional crust, so it is naturally gluten-free. Always check packaged ingredients if you need strict gluten avoidance.

Can I eat this cold?

Yes. This quiche tastes delicious warm, at room temperature, or chilled.

Cold slices are particularly convenient for meal prep.

What should I serve with it?

Serve with fresh berries, sliced tomatoes, cucumber, a green salad, fresh fruit, or roasted vegetables.
