What You’ll Need
This recipe calls for simple, fresh ingredients you probably already have in your pantry! Here’s what you’ll need:
- 1 pound grated zucchini: The star of the show! Choose fresh zucchini for the best flavor and moisture. A box grater works perfectly.
- ½ teaspoon salt: Enhances the flavors of the zucchini and eggs.
- 6 large eggs: Provides the base for the quiche and contributes to its texture. Use fresh, high-quality eggs for the best results.
- 1 cup heavy cream: Adds richness and creaminess to the quiche. Don’t substitute with milk; the heavy cream is essential for the texture.
- 8 oz smoked gouda cheese: This cheese adds a delightful smoky flavor. If you can’t find smoked gouda, you can use regular gouda and add a pinch (⅛ – ¼ teaspoon) of liquid smoke for a similar effect.
- 2 tablespoons snipped fresh chives: Provides a fresh, herby note to balance the richness of the cheese and cream.
- ½ teaspoon dried dill: Adds another layer of herby flavor, complementing the chives beautifully.
- ¼ teaspoon salt: Adds a touch of extra seasoning to the egg mixture.
- ¼ teaspoon white pepper: Adds a subtle spiciness without overpowering the other flavors.
- 2 teaspoons soft butter: Greases the baking dish to prevent sticking and ensures a smooth, even bake.
Step-by-Step Instructions
Get ready to whip up this delicious keto quiche in no time! Here’s a step-by-step guide:
- Prep the Zucchini: Grate the zucchini using a box grater. Place the grated zucchini in a colander and sprinkle with ½ teaspoon of salt. Gently toss to coat. Let it sit for about 10-15 minutes to allow excess moisture to drain. This step is crucial for preventing a watery quiche. After 15 minutes, gently squeeze out any remaining moisture with your hands or a clean kitchen towel.
- Preheat and Prep the Dish: Preheat your oven to 350°F (175°C). Grease an 8-inch pie dish or a similar-sized oven-safe dish with 2 teaspoons of softened butter. This prevents sticking and ensures easy removal.
- Whisk the Eggs: In a large bowl, whisk together the 6 large eggs and 1 cup of heavy cream until light and frothy. Be sure to whisk thoroughly to incorporate air for a light and fluffy texture. Tip: Use a fork or a whisk – whichever you prefer!
- Combine Ingredients: Add the drained zucchini, smoked gouda cheese (or gouda plus liquid smoke), snipped chives, dried dill, ¼ teaspoon salt, and ¼ teaspoon white pepper to the egg mixture. Gently fold everything together until well combined. Be careful not to overmix, as this can make the quiche tough.
- Bake the Quiche: Pour the mixture into the prepared baking dish. Bake for 40-45 minutes, or until the quiche is set and golden brown around the edges. A toothpick inserted into the center should come out clean. Tip: If the top starts browning too quickly, loosely cover it with foil for the last 15-20 minutes of baking.
- Cool and Serve: Let the quiche cool slightly before slicing and serving. This allows the quiche to set completely and makes it easier to slice neatly. Enjoy your delicious keto crustless zucchini quiche!
Tips for Success
Here are a few tips to help you achieve quiche perfection:
- Don’t skip the salting and draining: This step is critical for removing excess moisture from the zucchini, preventing a soggy quiche.
- Use fresh herbs: Fresh chives and dill add a brighter, more vibrant flavor than dried herbs.
- Don’t overmix the batter: Overmixing can lead to a tough quiche. Gently fold the ingredients together until just combined.
- Monitor the baking process: Ovens vary, so keep an eye on your quiche to ensure it doesn’t over-brown. If needed, cover it loosely with foil.
- Let it cool: Allowing the quiche to cool slightly before slicing prevents it from crumbling and makes for cleaner slices.
Variations to Try
Feel free to experiment with different flavors and ingredients!
- Add some spice: Incorporate a pinch of red pepper flakes for a touch of heat.
- Swap the cheese: Experiment with other keto-friendly cheeses like cheddar, parmesan, or mozzarella.
- Add different herbs: Try using fresh parsley, oregano, or thyme.
- Incorporate vegetables: Add sautéed mushrooms, spinach, or bell peppers for extra flavor and nutrients.
- Make it a vegetarian quiche: Omit the smoked gouda (or use a vegetarian substitute) and add your favorite vegetables for a satisfying vegetarian option.

Storing and Reheating
Leftover quiche can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, you can microwave it for 30-60 seconds, or bake it in a preheated oven at 350°F (175°C) for 10-15 minutes until heated through. Freezing is also possible; allow the quiche to cool completely, wrap it tightly in plastic wrap, and then place it in a freezer-safe bag. It should keep for up to 3 months. When ready to eat, thaw overnight in the refrigerator and reheat as directed.
