    Asparagus Crustless Quiche (gluten-free, grain-free, dairy-free & paleo options)

    By Alanna Taylor-Tobin on Mar 19, 2022 (updated May 29, 2022) / 11 Comments

    Easy asparagus crustless quiche made in under an hour that can be gluten-free, grain-free, and dairy-free! Whip this up for an effortless brunch or easy weekday breakfast. Leftovers keep wonderfully to enjoy throughout the week.

    I love a classic quiche with veggie-laden custard encased in a flaky, golden GF pie crust (or paleo pie crust). But for mornings (or afternoons, or evenings) when I need a main dish in under an hour, I turn to my favorite crustless quiche formula. 

    Crustless Quiche Vs. Frittata

    What's the difference between crustless quiche and frittata, you ask? Well frittata is made from beaten eggs plus goodies cooked on the stove or baked. But quiche adds milk and/or cream for a more tender, custardy filling. 

    While most crustless quiche recipes are just frittata in disguise, this recipe uses a more custardy ratio of dairy to eggs. A little flour absorbs moisture and the result is somewhere between luscious quiche filling and a puffy oven pancake. It's divine, and simply satisfying.

    I learned this formula several years ago from a friend and shared a springy potato green garlic version. Today I'm sharing this simple asparagus crustless quiche made with lots of gooey, melty cheese and made grain-free with cassava flour.

    This quiche is casual enough for a lazy Sunday brunch, but tasty enough to serve guests for a light but substantial supper. The delicate custard creates an elegant foil for grassy asparagus and nutty gruyere cheese. See below for pairing suggestions!

    ingredients for crustless quiche

    Ingredients and Substitution Suggestions

    • Eggs form the base of this crustless quiche. If you can use pastured eggs, you'll be rewarded with especially bright & flavorful egg yolks!
    • Milk and cream add moisture and richness. For dairy-free crustless quiche, use full-fat coconut milk – it works beautifully and doesn't taste like coconut!
    • Flour absorbs excess moisture. I've used grain-free cassava and arrowroot flours here, but any all-purpose flour (wheat, GF, or Paleo) should work. I've also used a mix of sweet rice and GF oat flour. It's a forgiving recipe, so feel free to experiment with your preferred flours!
    • Asparagus cooked briefly in butter adds its delightfully grassy flavor, but you can use pretty much any seasonal vegetable such as broccoli, zucchini, cherry tomatoes, peppers, mushrooms, or greens. See the notes section below the recipe for more ideas!
    • Cheese adds umami flavor and melty goodness. I used gruyere here, which has a lovely nutty flavor that pairs beautifully with asparagus. But any mild melting cheese will work, such as gouda or Swiss. Fresh goat cheese is another favorite option!
    • Chives add oniony goodness. Green onions work well too. Or use sautéed leek or shallot.
    • Salt and pepper sharpen the flavors.

    How to Make Crustless Quiche

    prepared asparagus pieces and tips

    Prep the asparagus by snapping off the woody ends (they'll break naturally at a good spot). Slice off the top 2 inches of the tips and leave them whole, then slice the stalks into half-inch thick slices. Lightly sauté the asparagus in butter.

    adding the eggs to the flour mixture

    Whisk together the cassava flour, arrowroot starch, salt and pepper. Add two of the eggs and whisk smooth. This prevents the flour from clumping.

    Add the remaining four eggs, two at a time, whisking well after each addition.

    the finished custard in a blue bowl

    Whisk in the milk, cream, and chives.

    asparagus and cheese in the pan

    Spread the asparagus pieces in the pan and top with some of the cheese.

    custard added to the pan

    Pour in the custard.

    asparagus tips on top of the quiche

    Top with the asparagus tips.

    Bake the quiche until puffed and golden. Let cool slightly, then cut into wedges and serve warm or at room temperature.

    Allergy-Friendly Variations

    Gluten-Free Crustless Quiche

    If grains aren't an issue, use sweet rice and GF oat flour (see recipe notes for the amounts) or a good all-purpose GF flour such as Bob's Red Mill 1 to 1.

    Grain-Free Crustless Quiche

    Make the recipe as written with cassava and arrowroot flours.

    Dairy-Free Crustless Quiche

    To ditch the dairy, simply swap the milk and cream for full-fat coconut milk. Use olive oil instead of butter for cooking the asparagus. Omit the cheese or use a good vegan cheese. I'm a fan of Miyoko's vegan mozzarella with their chive or sun-dried tomato soft cheese wheels.

    Paleo Crustless Quiche

    Make the above subs, and use cassava and arrowroot flours.

    What to Serve with Quiche?

    Quiche needs nothing more than a simple green salad tossed with dijon vinaigrette and a glass of white wine or bubbles to make it a meal. But here are a few favorite brunch-friendly pairings:

    • Sparkling Grapefruit Elderflower Cocktails
    • Green Goddess Potato Salad
    • Cucumber Quinoa Salad with Feta & Herbs
    • Spring Greens Salad with Miso Buttermilk Dressing
    • Roasted Potatoes and Parsnips
    • My favorite basil pesto

    However you serve up this crustless asparagus quiche, I hope it becomes a brunch staple in your home like it has in ours!

    Asparagus Crustless Quiche (gluten-free & grain-free)

    Print Recipe Pin Recipe
    While many crustless quiche recipes are just frittata in disguise, this asparagus crustless quiche uses a more quiche-like ratio of eggs to dairy, plus a little flour, for something closer to a puffy oven pancake or dutch baby.
    Alanna Taylor-Tobin
    Prep Time: 10 minutes minutes
    Cook Time: 45 minutes minutes
    Total: 55 minutes minutes
    Servings: 3

    Ingredients

    • 1 tablespoon butter, plus a little for the pan
    • 1 bunch asparagus (12-16 ounces)
    • ¼ cup (33 g) cassava flour*
    • 3 tablespoons (21 g) arrowroot starch*
    • ½ teaspoon fine sea or kosher salt
    • black pepper
    • 6 large eggs
    • 1 cup whole milk (or full-fat canned coconut milk)
    • ¼ cup heavy cream (or full-fat canned coconut milk)
    • 2-3 tablespoons chopped chives or scallion greens
    • 4 ounces (1 cup lightly packed) gruyère or other favorite cheese*

    Instructions

    • Position a rack in the center of the oven and preheat to 350ºF. Rub a 9 or 10-inch round baking pan with softened butter.
    • Snap the ends off of the asparagus. Cut the stalks into half-inch pieces on diagonal, leaving the asparagus tips intact.
    • In a wide skillet, melt ½ tablespoon of the butter over medium heat. Add the small asparagus pieces plus a big pinch salt. Cook, stirring, until bright green and crisp tender. Remove from pan.
    • Add the remaining butter and asparagus tips & cook for one minute.
    • In a large bowl, whisk together the cassava flour, arrowroot starch, salt and pepper. Add two of the eggs and whisk smooth. Add the remaining four eggs, two at a time, whisking well after each addition. Whisk in the milk, cream, and chives.
    • Spread the small pieces of asparagus in the bottom of the pan. Sprinkle most of the cheese over the asparagus pieces. Pour the quiche batter over the asparagus and arrange the asparagus tips on top. Sprinkle with the remaining cheese.
    • Bake the quiche until puffed and golden, 40-45 minutes. Let cool for a few minutes, then cut into wedges. Serve warm or at room temperature.

    Notes

    *For a gluten-free quiche that isn't grain-free, sub 1/4 cup sweet rice flour or GF all-purpose flour + 1/4 cup GF oat flour for the cassava and arrowroot flours. If gluten isn't an issue, you can make this with 1/3 cup all-purpose wheat flour. 
    *You can use any cheese you love here in place of or in addition to gruyère. Fresh goat cheese, parmesan, or other mild melty cheeses like gouda, swiss, or jack would be delicious too.
    For dairy-free / paleo crustless quiche, use canned coconut milk in place of the dairy and vegan butter or olive oil in place of the butter. Omit the cheese or use a good vegan cheese. I like a combination of Miyoko's mozz and some of their soft chive wheel or sun-dried tomato wheel. 
    Feel free to use this GF crustless quiche formula with other ingredients instead of or in addition to the asparagus such as:
    • sautéed mushrooms 
    • sautéed leeks or spring onions
    • cherry tomatoes or sun-dried tomatoes
    • sautéed zucchini
    • lightly steamed broccoli
    • wilted spinach or other greens
    • other herbs such as tarragon, basil, thyme, etc.
    • sweet corn
    • roasted winter squash
    • parboiled potato slices
    • bacon, sausage, or pancetta for omnivores
    Nutritional values are based on one of three servings.

        That's a great question! Eggs are tricky to substitute. But here's a version that uses tofu! You could also try use Just Egg. Let me know what you try!

    This gluten-free Basque-style burnt cheesecake has This gluten-free Basque-style burnt cheesecake has a secret ingredient: Vermont Creamery fresh goat cheese! It adds a bright, tangy flavor and velvety texture. 

Think crème brulee meets cheesecake. Break through the caramelized sugar crust to the creamy center that’s light and airy like a cloud, yet rich and dense at the same time. 

Basque-style cheesecake has no crust, but a high oven temperature browns the outer edges to keep slices intact. Use sweet rice flour to make it gluten-free if you like!

    Gluten-Free #treslechescake (DF option) Last week Gluten-Free #treslechescake (DF option)

Last week I shared my favorite gluten-free sponge cake recipe, and here's another fun way to use it. Add an extra egg white to the batter and soak the cake with sweet milks (or coconut milks) for a gluten-free (and optionally dairy-free) riff on the beloved Latin-American sweet. 

I developed the gluteny version of this recipe during my years as a pastry chef at a Latin-American restaurant here in SF. I would bake the cake in a large hotel pan, cut out rounds to make individual cakes for plating, and promptly devour all the cake scraps. 

While I don't recommend having cake for lunch, I do recommend whipping up a tres leches cake for your next gathering. They're brilliant for parties because they can be made a day or two ahead and refrigerated until ready to serve. 

Top slices with whipped cream (or whipped coconut cream) and fresh berries or, more traditionally, a layer of cinnamon sifted over the top. Creamy, comforting deliciousness. 

The last shot is the coconut flour tres leches cake from #alternativebakerbook topped with lime-kissed mango. So fresh!

    As blueberries come into season here in California As blueberries come into season here in California, I've been dreaming about this gluten-free blueberry coffee cake. It's moist and tender, layered with jammy fruit and an addictively salty-sweet streusel topping. 

Oat flour, sorghum flour, and sweet rice flour build a moist and flavorful cake, and almond flour in the topping helps the streusel hold together. 

It would be an ideal addition to weekend brunch or potlucks, and it takes well to variations. I've made it with rhubarb instead of berries, for instance - so good!

Here are a few things readers have said about this cake:

"Better than any gluten-full coffee cake I ever had. This recipe is a keeper. THANK YOU!!" 

"So this is the best coffee cake I’ve ever had, GF or otherwise! Another genius recipe!"

"This was such a hit last night served as a dinner dessert. People were having seconds and thirds! It was absolutely delicious, fluffy and moist and flavorful with a crunch from the pecans on top." 

"This coffee cake is so good - a light, tender crumb and with a pleasant touch of lemon. If I didn’t know it was gluten free I wouldn’t even suspect so."
