Ingredients for Keto Crustless Zucchini Quiche

Let’s break down what you’ll need to create this vibrant, nutritious Keto Crustless Zucchini Quiche:

• 1 pound zucchini, grated: The star ingredient brings moisture, freshness, and a subtle earthiness.
• 1/2 teaspoon salt (for salting the zucchini): Draws out excess liquid, preventing a soggy quiche.
• 1/2 teaspoon dried dill: Provides a classic herbal note that pairs beautifully with zucchini.
• 2 tablespoons chives: Delivers a hint of mild onion flavor and color.
• 4 large eggs: The backbone of the custard, adding structure and nutrition.
• 1/4 cup heavy cream: Creates a silky, rich filling while keeping the carbs low.
• 1/4 teaspoon salt (for custard): Enhances all the other flavors.
• 1/4 teaspoon ground black pepper: Adds gentle warmth.
• 6 ounces smoked gouda cheese, grated: Melts into the eggs and veggies for a satisfyingly smoky, cheesy bite.

Optional garnishes: fresh herbs, a sprinkle of chili flakes, or an extra dusting of gouda for serving.

Necessary Tools

Making this Keto Crustless Zucchini Quiche is refreshingly straightforward, requiring only basic kitchen equipment:

• Large colander: Essential for draining water from the grated zucchini, which ensures a firm and sliceable quiche.
• Mixing bowls: At least two—one for the zucchini and one for the egg mixture.
• Box grater or food processor: For grating zucchini and cheese.
• Whisk: To help achieve a frothy, well-mixed egg custard.
• 9- to 10-inch pie plate or quiche dish: Ensures even baking and an attractive presentation. Ceramic works especially well.
• Baking sheet (optional): Can be placed under the pie dish to catch any potential drips.
• Cheesecloth or clean kitchen towel: Useful for squeezing out as much water from the zucchini as possible.
• Sharp knife and serving spatula: For portioning and serving your beautiful quiche.

No stand mixers, fancy gadgets, or complicated processes—just classic tools for classic results!

Ingredient Additions & Substitutions

A Keto Crustless Zucchini Quiche is wonderfully versatile—here’s how you can switch up ingredients to suit your preferences, dietary needs, or pantry supplies:

• Cheese Swap: If you don’t have smoked gouda, or you’d love a different flavor, try sharp cheddar, Fontina, Swiss, mozzarella, or even a tangy blue cheese for a bolder taste. Smoked provolone or a blend of cheeses also works well, depending on what’s in your fridge.
• Green Options: No zucchini? Try a combination of grated yellow squash, cooked broccoli, chopped spinach (squeeze it dry), or even kale. Each adds its own texture and nutrients, and most keep the carb count low.
• Herb Variations: Fresh dill isn’t for everyone—swap in parsley, basil, thyme, or tarragon. Green onions or finely minced shallot can stand in for chives if needed.
• Dairy Alternatives: For lactose intolerance, use coconut cream or unsweetened almond milk (the quiche will be slightly less rich). You can also try lactose-free cheese options.
• Amp Up the Protein: Fold in cooked, crumbled bacon, diced ham, smoked turkey, or shredded rotisserie chicken for a heartier, more filling quiche. A little goes a long way.
• Vegetable Add-ins: Roasted red pepper strips, sautéed mushrooms, sun-dried tomatoes, or even lightly caramelized onions bring bursts of color and flavor.
• Egg Substitutes: If egg allergies are a concern, plant-based egg substitutes can be used, though the quiche won’t set exactly the same way. Expect a slightly different texture, but similar depth of flavor.
• Crust Option for Non-Keto Guests: If you’re feeding a mix of keto and non-keto diners, prepare a second quiche with a traditional buttery pie crust in a separate pie dish, following the same filling instructions.

Remember—one of the best things about this quiche is its adaptability. Don’t hesitate to experiment with fridge clean-out ingredients or seasonal produce!

How to Make Keto Crustless Zucchini Quiche

This delicious quiche comes together in under an hour and is virtually foolproof. The layering technique gives every bite plenty of cheesy, herb-studded zucchini and luscious custard. Here’s your easy step-by-step guide to keto quiche brilliance:

Step 1: Prep and Salt the Zucchini

Grate a pound of fresh zucchini using a box grater or food processor. Place the shreds in a large colander and sprinkle with 1/2 teaspoon salt, tossing gently to distribute. Let sit over the sink for 10 minutes—this draws out excess moisture, which keeps your quiche light rather than watery.

Step 2: Preheat and Prep Your Dish

While the zucchini drains, preheat your oven to 350°F (177°C). Generously butter a 9

• or 10-inch pie plate or quiche dish; this will help the quiche release easily after baking and lend a touch of richness to the crustless edge.

Step 3: Squeeze and Combine

After the zucchini has rested, rinse it well under cold water to remove any bitterness from the salt. Squeeze firmly by the handful (or wring out in a cheesecloth or clean towel) to expel as much liquid as possible. In a bowl, combine with 1/2 teaspoon dried dill and 2 tablespoons chopped chives.

Step 4: Prepare the Egg Mixture

In another mixing bowl, whisk together 4 eggs, 1/4 cup heavy cream, 1/4 teaspoon salt, and 1/4 teaspoon pepper until frothy and well-combined. This creates your quiche’s dreamy custard base.

Step 5: Layer Cheese, Zucchini, Repeat

Begin assembling the quiche: Sprinkle about 1/4 of your grated gouda in the bottom of your prepared pie dish, then spread 1/3 of the zucchini mixture on top. Repeat two more times, layering cheese and zucchini, finishing with the remaining cheese for a golden, bubbling surface after baking.

Step 6: Pour and Bake

Pour your egg mixture slowly and evenly over the layered zucchini and cheese, tapping the dish gently to settle the custard into all the nooks. Transfer the quiche to the oven and bake for 40–50 minutes until deeply golden, puffed at the edges, and just slightly soft in the middle.

Step 7: Cool and Serve

Cool at room temperature for at least 15–20 minutes before slicing. This helps the quiche set and delivers neat, clean pieces. Serve warm, at room temperature, or even cold—it’s delicious at every temperature!

How to Serve Keto Crustless Zucchini Quiche

Whether you’re hosting brunch, prepping grab-and-go breakfasts, or creating a satisfying dinner, Keto Crustless Zucchini Quiche is as flexible as your schedule. Slice it into wedges and garnish with fresh herbs, avocado slices, or a sprinkle of chili flakes for added flair. Pair with a simple green salad with vinaigrette, sautéed greens, or a fresh tomato-cucumber salsa for extra color. For heartier appetites, serve alongside roasted chicken, smoked salmon, or a few slices of crispy bacon. This quiche is perfect atop a festive brunch table, nestled in a lunchbox, or as a no-fuss, guilt-free dinner option on busy nights.

Pro Tips & Tricks

Getting the perfect Keto Crustless Zucchini Quiche every time is easy with these chef-approved tips:

• Maximize Zucchini Dryness: Squeeze out every drop of water—you’ll be amazed at how much liquid zucchini holds! This will keep your quiche sliceable and prevent sogginess.
• Whip It Good: Whisk the eggs and cream until frothy—this lifts the custard, making it extra light and tender.
• Let It Rest: Allow the quiche to cool for at least 15 minutes after baking. This helps the quiche set and develop extra flavor.
• Golden Top: If your cheese isn’t browning, broil the quiche for 1–2 minutes at the end of baking, keeping a close eye to avoid burning.
• Even Baking: Use a ceramic or glass quiche dish for even heat distribution and the prettiest presentation.
• Flavor Boost: Smoked gouda’s richness is incredible, but you can also add a pinch of nutmeg or cayenne to the egg mix for a subtle kick.
• Custom Cuts: For neat slices, use a sharp, thin-bladed knife, wiping it clean between cuts.
• Freezing for Later: Flash freeze individual slices, then reheat in the microwave or oven for a speedy keto breakfast or snack.

Storage Instructions

Store any leftover Keto Crustless Zucchini Quiche in an airtight container in the refrigerator for up to 4 days. For optimal texture, let individual slices come to room temperature or gently reheat them in a 300°F oven for 10–15 minutes—this brings back the quiche’s just-baked softness and flavor. If freezing, first chill the quiche completely, then wrap slices tightly in plastic wrap and store in a freezer-safe bag or airtight container for up to one month. Thaw overnight in the fridge before reheating, avoiding the microwave as it can make the custard rubbery or the zucchini watery.

FAQs

Can I use frozen zucchini for Keto Crustless Zucchini Quiche?

Yes, but be sure to thaw and squeeze out all excess water; frozen zucchini tends to release more liquid than fresh.

Is smoked gouda necessary, or can I use another cheese?

Smoked gouda adds depth, but any well-melting cheese—cheddar, mozzarella, or Swiss—works beautifully. Mix and match for custom flavor.

How do I know when my quiche is set?

Your quiche is done when it’s golden brown at the edges, slightly puffed, and the center jiggles just a bit but isn’t soupy. It will set further as it cools.

Can I bake this recipe in advance?

Absolutely! Bake the day before, cool, and refrigerate. Serve cold or rewarm gently, covered, in the oven before serving.

Why is my quiche watery?

Insufficiently drained zucchini is the main culprit—always thoroughly squeeze after salting, and avoid watery add-ins.

Do I need to grease the pie plate if I use a nonstick pan?
