So last Tuesday I’m standing in my kitchen staring at seventeen zucchini from my garden, and my husband gives me this look like “not more zucchini bread, please.” I threw together this Crustless Zucchini Quiche recipe mostly out of desperation, but oh my word – it was spectacular! Now it’s become our go-to weekend breakfast, and even my picky eater nephew asks for seconds.
❤️ Why You’ll Love This Recipe
Look, I’m not exaggerating when I say this beats every quiche I’ve ever made, and I’ve been at this for decades. The smoky cheese gets all melty and rich, the zucchini tastes like tender noodles, and somehow it all holds together without any crust nonsense. My sister brought her kids over Sunday and they cleaned the entire pan – didn’t even realize it was “healthy.” Four carbs per slice means I can eat two pieces and still stay in ketosis, which is basically a miracle.
Keto Crustless Zucchini Quiche
- Total Time: 1 hour 5 minutes
- Yield: 1 quiche 1x
Description
This Crustless zucchini quiche features a rich, creamy custard filling infused with tender zucchini, fragrant herbs, and the smooth, savory flavor of smoked Gouda — a perfectly balanced and delicious combination.
Ingredients
-
- 1 pound fresh zucchini (about 2–3 medium zucchini), grated
-
- 1 teaspoon salt (for draining zucchini)
-
- 8 ounces smoked Gouda cheese, freshly grated (about 2 cups)
-
- 6 large eggs
-
- ½ teaspoon salt
-
- ¼ teaspoon white pepper
-
- 2 tablespoons fresh chives, snipped
-
- ½ teaspoon dried dill
-
- Optional: 1-2 drops liquid smoke (if using regular Gouda)
Instructions
Step 1: Tame That Zucchini Grate your zucchini using the big holes on your grater. Toss it with a teaspoon of salt like you’re seasoning a salad, then walk away for exactly ten minutes. This is when the magic happens – the salt draws out water like you wouldn’t believe. After ten minutes, rinse it under cold water until the water runs clear, then comes the fun part: squeeze the life out of it. I wrap mine in a clean dish towel and twist it into a bundle, then squeeze until my hands hurt. You want it drier than you think is possible.
Step 2: Get That Oven Ready Crank your oven to 350°F and butter that pie dish like your life depends on it. Don’t use cooking spray – real butter creates the best golden bottom.
Step 3: Whisk Like You Mean It Crack those six eggs into your biggest bowl and whisk them until they’re pale and slightly foamy. Season with salt, white pepper, chives, and dill. The mixture should smell fresh and herby, like a spring garden.
Step 4: Layer Like a Pro This step separates the amateurs from the pros: scatter half your grated Gouda across the bottom of your buttered dish. Spread the squeezed zucchini evenly over the cheese, then top with the remaining Gouda. This sandwich method keeps everything balanced and prevents the dreaded soggy bottom.
Step 5: The Grand Finale Pour your egg mixture slowly over everything, letting it seep into all the nooks and crannies. Give the dish a gentle shake – not violent, just a little shimmy to settle everything.
Step 6: Into the Fire Slide it into your oven and set a timer for 40 minutes. Check it then – the center should be just barely jiggly when you give the pan a gentle shake. If it’s still too wobbly, give it another 5-10 minutes. The top will be golden and gorgeous when it’s ready.
Step 7: The Waiting Game This is torture, but let it cool completely before cutting. I know it smells incredible, but cutting too early results in a messy, runny disaster. Trust me on this one.
Notes
If smoked Gouda isn’t available in your area, regular Gouda with a drop of liquid smoke works perfectly. Don’t get creative with extra vegetables unless you account for their moisture content – this recipe is calibrated for zucchini’s water content specifically. The white pepper might seem fancy, but it keeps the appearance clean and bright.

📝 Ingredient List
For the Quiche:
- 1 pound fresh zucchini (about 2-3 medium zucchini), grated
- 1 teaspoon salt (for draining zucchini)
- 8 ounces smoked Gouda cheese, freshly grated (about 2 cups)
- 6 large eggs
- ½ teaspoon salt
- ¼ teaspoon white pepper
- 2 tablespoons fresh chives, snipped
- ½ teaspoon dried dill
- Optional: 1-2 drops liquid smoke (if using regular Gouda)
Substitutions that work:
- Cheese: Regular cheddar’s fine but you lose that smoky kick. Gruyère makes it fancy.
- Herbs: Got fresh dill? Use it. Thyme’s good too.
- Extras: Bacon bits turn this into dinner material.
🔍 Why These Ingredients Work
Here’s the deal with zucchini – it’s basically a water balloon disguised as a vegetable. You grate it up and it looks innocent enough, but skip the draining step and your quiche turns into soup. I learned this the expensive way when I ruined a whole Sunday brunch for eight people. The smoked Gouda costs more than regular cheese but it’s worth every penny – tastes like someone spent hours smoking meat when really you just opened a package. Six eggs seems excessive but they’re doing all the work here, creating that creamy center while keeping everything from falling apart. Fresh chives cut through all that richness, and the dill makes it taste fancy without trying too hard.
Essential Tools and Equipment
Nothing complicated here – just grab your trusty box grater, a big mixing bowl, and that pie dish you probably haven’t used since Thanksgiving. A clean kitchen towel is essential for squeezing the zucchini dry. I learned this lesson when I tried using paper towels and ended up with soggy paper bits in my quiche – not my finest culinary moment!

Tips from Well-Known Chefs:
My aunt Rosa, who cooked for an Italian restaurant for thirty years, always said the secret to perfect egg dishes is patience – room temperature eggs blend smoother, and cooling time lets everything set properly. She was right about everything else, so I listen to her on this too.
❗ You Must Know
Personal Secret: After my third watery disaster, I discovered the paper towel trick wasn’t enough. Now I salt the zucchini, drain it, rinse it, then squeeze it in a towel until I think I’m being ridiculous. Then I squeeze it some more. This extra step makes the difference between restaurant-quality quiche and expensive compost.
💡 Pro Tips & Cooking Hacks
Buy a block of Gouda and grate it yourself – those pre-shredded bags are coated with potato starch that prevents proper melting. Room temperature eggs incorporate faster and create a smoother custard. Don’t open the oven door for the first 35 minutes – sudden temperature changes can cause cracking.
Watch for these rookie mistakes: skipping the zucchini prep (disaster), using cold eggs (lumpy texture), or cutting while hot (runny mess). I’ve made every one of these errors, so you don’t have to.
🎨 Flavor Variations / Suggestions
Once you’ve mastered the basic recipe, the world opens up. Try Mediterranean style with sun-dried tomatoes and kalamata olives – it tastes like vacation. For breakfast lovers, fold in crispy bacon or breakfast sausage. Garden variety includes whatever vegetables are begging to be used up in your crisper drawer. My personal favorite is the herb garden version with fresh rosemary and thyme – it’s like eating a summer meadow.
⏲️ Make-Ahead Options
Sunday meal prep just got easier. Assemble this Saturday night and bake fresh Sunday morning for that “I’ve been cooking all day” aroma without the work. It keeps beautifully in the fridge for four days, perfect for grab-and-go breakfasts when you’re running late. Individual frozen slices last three months and reheat like a dream – better than any frozen breakfast you can buy.
Recipe Notes & Baker’s Tips
If smoked Gouda isn’t available in your area, regular Gouda with a drop of liquid smoke works perfectly. Don’t get creative with extra vegetables unless you account for their moisture content – this recipe is calibrated for zucchini’s water content specifically. The white pepper might seem fancy, but it keeps the appearance clean and bright.
🍽️ Serving Suggestions
This quiche doesn’t require much in the way of company, but it does love a simple arugula salad with a nice lemon dressing. For brunch, somebody bring home the bacon — all crispy and on the side. Dinner calls for roasted vegetables or a fresh tomato salad from the garden.A dollop of sour cream and more chives and the whole thing could pass for something out of a fancy brunch place.
I hope this is a recipe that makes it into your regular rotation much as it has mine. There’s something deeply satisfying about elevating the modest zucchini into something this classy and delicious! 🍽️
🧊 How to Store Your Keto Crustless Zucchini Quiche
Room temperature works for about two hours if you’re serving it the same day. Refrigerate covered for up to four days – it actually tastes better the next day after the flavors meld. Freeze individual slices wrapped tightly for up to three months. Reheat gently in a 300°F oven for 10-15 minutes, or zap individual slices for 30-60 seconds in the microwave.
⚠️ Allergy Information
This contains eggs and dairy, obviously. It’s naturally gluten-free, which makes my celiac neighbor very happy. For dairy-free versions, you’ll need to experiment with dairy-free cheeses that actually melt – not all of them do. Unfortunately, eggs are non-negotiable here since they provide the structure.
❓ Questions I Get Asked A Lot
Can I freeze zucchini for this recipe?
I have tested it and its work but the fresh zucchini give better texture. Frozen releases even more water, so you’ll need to be extra aggressive with the draining process.
Why is my quiche watery?
Nine times out of ten, the zucchini wasn’t drained well. Salt, drain, rinse, squeeze, then squeeze some more. It should feel almost dry when you’re done.
Can I prepare this in advance?
Absolutely. Make it the night before and bake it fresh, or bake it all the way and reheat. Both methods work beautifully.
How do I know when it’s done?
It should barely jiggle when you shake the pan, and it should be golden brown on top. A knife inserted in the center comes out mostly clean.
Can I add meat to this recipe?
Definitely! About half a cup of cooked bacon, ham, or sausage works perfectly. Add it with the zucchini layer.
