This family-size crustless quiche turns a dozen eggs, grated zucchini, kale, garlic, aged cheddar, Parmesan, and homemade 24-hour sour cream into one substantial Full GAPS breakfast. There is no pastry crust, flour, or hidden starch.

The method is built around moisture control. Most of the zucchini is salted, rinsed, and squeezed before it meets the cheese. The quiche then bakes in three stages so the reserved zucchini rounds and final cheddar layer go on at the right times.

A Big Quiche for a Full House

This is the kind of breakfast that makes sense when one pie plate is not enough. Twelve eggs and a four-quart dish give you eight or more servings, with enough structure to cut clean squares after the quiche rests.

In our house, a large baked breakfast works because the oven does the final hour while I move on to everyone else’s morning. The zucchini preparation takes attention up front, but the finished dish can feed the table at once instead of keeping me at the stove cooking individual portions.

If you make the sour cream or ghee at home, those component recipes are linked where you need them. You can open them while you cook without crowding this page with a second recipe card.

Where This Quiche Fits on GAPS

This is a Full GAPS recipe after homemade sour cream and natural aged cheese have been introduced and tolerated. It is not an Introduction Diet recipe and it is not dairy-free.

Use homemade yogurt-culture sour cream cultured for at least 24 hours. Natural aged cheddar and Parmesan need simple, appropriate ingredient lists without starches, gums, colorants, or other additives.

If your family has not reached cultured cream and natural aged cheese yet, save this one for later instead of substituting unfermented commercial cream.

Measure and Divide the Ingredients Before Starting

Set out 12 eggs; four large zucchini or five average zucchini; four large kale leaves; four cups grated aged cheddar divided into two equal portions; two cups homemade sour cream; one cup grated Parmesan; two teaspoons sea salt plus a separate one-half teaspoon; and two quartered garlic cloves.

Reserve one zucchini for the top and slice it into even rounds. Grate the remaining zucchini. Keep the two cheddar portions separate: the first two cups mix with the squeezed zucchini, while the final two cups become the top layer after the second baking stage.

Choose butter, homemade stovetop ghee, natural non-hydrogenated coconut oil, duck fat, lard, or tallow to grease the dish. Use a fat already appropriate for the eater.

Salt the Grated Zucchini for Thirty Minutes

Toss the grated zucchini with exactly two teaspoons sea salt. Let it stand for 30 minutes. This salt belongs to the draining step and remains separate from the one-half teaspoon used in the egg custard.

During the rest, the shreds soften and release a visible pool of pale green liquid. If the bowl still looks almost dry, give the zucchini the full time rather than rushing ahead.

About 10 minutes before the rest ends, heat the oven to 375°F so the dish can go into a fully heated oven after assembly.

Drain, Rinse, and Squeeze Until Only Drops Remain

Move the salted zucchini into an uncoated stainless colander and rinse it well. Rinsing removes the excess two teaspoons of salt before the shreds join the custard.

Squeeze the zucchini in handfuls until only a few drops come out under firm pressure. Wet shreds leave water in the bottom of the quiche and dilute the eggs. Properly squeezed zucchini feels soft and compact rather than dripping.

The drained liquid shown in the method photo is the moisture you are keeping out of the finished custard.

Blend the Kale-Egg Custard in Two Short Stages

Put the 12 eggs, four kale leaves, and eight garlic quarters into a Ninja Professional Plus Kitchen System BN801. Blend on low for about 15 seconds, pulsing as needed, only until the kale is broken into small even pieces with no large leaves remaining.

Add the two cups homemade sour cream and the separate one-half teaspoon sea salt. Blend for just 5 to 10 seconds, until the cultured cream disappears into the eggs. Stop once the custard is evenly pale green.

Long blending whips in unnecessary air and makes it harder to judge the final set. The goal is an even custard, not foam.

Build the Zucchini-Cheese Base

In a medium bowl, toss the squeezed zucchini with the first two cups aged cheddar and all one cup Parmesan. Separate any dense clumps of zucchini so the cheeses are distributed through the shreds.

Grease the four-quart Le Creuset Heritage baking dish in Artichaut with the tolerated fat. Reach the corners and sides so the egg edges release after baking.

Spread the zucchini-cheese mixture into an even base. Press down only enough to level it; packing it hard creates a dense lower layer.

Pour the Custard and Check the Unbaked Surface

Pour the kale-egg custard over the zucchini-cheese base. Move the bowl around the dish so the liquid reaches every corner instead of collecting in the center.

The surface should be level, pale green, and fluid, with fine kale flecks and grated zucchini visible. At this stage there are no zucchini rounds and no final cheddar layer on top.

Bake in Three Measured Stages

Bake the uncovered quiche for 25 minutes. The edges begin to set while the center remains soft. Using oven mitts, remove the hot dish and set it on a heat-safe surface before arranging the reserved zucchini rounds over the surface.

Return it to the oven for 15 minutes. Remove it again and scatter the remaining two cups cheddar evenly across the top, including the corners.

Bake for about 20 minutes more. The complete baking time is about one hour, but the center temperature and physical set control the endpoint.

Check for a 165°F Center

Insert an instant-read thermometer into the center without touching the bottom of the dish. The quiche is done when the center reaches 165°F.

The top should look puffed and set, the cheddar should be melted with light golden areas, and no liquid egg should move when the dish is shifted gently. The quiche may rise in the oven and settle slightly as it rests.

If the center is below temperature, return it to the oven and check again after a short interval instead of guessing from the browned edges.

Rest Before Cutting

Let the quiche stand for 5 to 15 minutes. The rest allows the custard to finish settling so the first square does not collapse or leave a wet trail.

Cut with a sharp knife and lift portions with a wide stainless spatula. A clean slice shows grated zucchini and small kale flecks held in a moist egg-and-cheese custard.

What the Finished Quiche Should Taste Like

The cultured sour cream gives the eggs a gentle tang, aged cheddar provides the main savory flavor, and Parmesan sharpens the zucchini base. Kale and garlic should be present without forming tough pieces.

The center is moist and set rather than dry or rubbery. A watery layer points back to zucchini that needed more squeezing. Large kale ribbons mean the first blending stage stopped too soon.

Serving Ideas

Serve warm for breakfast, lunch, or a simple dinner. A crisp Full GAPS salad, fermented vegetables, or softly cooked vegetables can round out the plate.

Optional sliced green-onion tops may be added after baking when tolerated. I left them off the photographed quiche so you can clearly see the browned cheese and the set around each zucchini round.

With side dishes, the eight-serving quiche can stretch farther. Keep portions in the dish until serving so they stay warm and supported.

Storage and Reheating

Cover leftovers and refrigerate them. Use within four days. Cool the dish promptly rather than leaving the egg-and-dairy custard at room temperature.

To reheat, cover the quiche and warm it in a 300°F oven until the center reaches 165°F. A single portion may take about 20 minutes; a larger section may take about 35 minutes. Follow the thermometer rather than time alone.

The quiche is also pleasant cold once properly chilled, although the cheddar will be firmer.

Recommended Equipment

Use a box grater or food-processor grating disk, uncoated stainless colander, large bowl, measuring cups and spoons, the Ninja Professional Plus Kitchen System BN801, the four-quart Le Creuset Heritage rectangular baking dish in Artichaut, an instant-read thermometer, a sharp stainless knife, and a wide stainless serving spatula.

Frequently Asked Questions

Is This Crustless Quiche GAPS Legal?

Yes, on Full GAPS after homemade 24-hour sour cream and natural aged cheddar and Parmesan are introduced and tolerated.

Why Use Sour Cream Instead of Heavy Cream?

This formula uses homemade sour cream cultured for at least 24 hours. Unfermented cream is not the measured GAPS form here.

Can I Use Gruyère?

You can replace some or all of the cheddar with additive-free natural aged Gruyère after that cheese has been introduced and tolerated. Keep the Parmesan and the total four-cup aged-cheese measurement the same.

Do I Have to Salt the Zucchini?

Yes. The 30-minute salt rest, rinse, and thorough squeeze remove water that would otherwise collect in the custard.

Why Is the Quiche Still Wet?

Check that the grated zucchini was squeezed until only drops remained and that the center reached 165°F before the dish left the oven.

Can I Make It in a Smaller Dish?

Use the four-quart dish or another baking dish with comparable capacity and depth. A smaller, deeper vessel changes the baking time and can leave the center wet after the edges are done.
