What’s A Crustless Zucchini Quiche?

A Crustless Zucchini Quiche is a quiche with no crust! They are the perfect keto quiches since they don’t have the carb from the wheat crust.

Although there are a few ways to bake a crustless zucchini quiche, it can be baked in a large 9-inch quiche pan or in muffin trays for a single-serve breakfast.

How To Make Crustless Zucchini Quiche

This is a muffin tray recipe which means that each crustless quiche is baked in a jumbo 8-hole muffin tray.

You only need a handful of healthy, wholesome ingredients to make it.

Key Ingredients

  • Zucchini – Zucchinis are keto-friendly vegetables. They need to be cut or shaved in thin ribbons to make it easy to shape the quiches. And more zucchinis will be used to make a low-carb pesto mixture.
  • Onion – for the pesto mixture. I prefer to use yellow onions, but you can use red onions if you prefer.
  • Pesto – you can either buy it ready-made or make your own low-carb pesto. All you need is olive oil, fresh basil, Parmesan cheese, lemon zest, and pine nuts. Ground the lot to make keto pesto.
  • Eggs – pick large, free-range eggs. Eggs are keto-friendly ingredients.
  • Almond Milk – prefer unsweetened, unflavored almond milk. You can replace almond milk with any other dairy-free milk such as oat milk, or coconut milk.
  • Parmesan – Parmesan is one of the keto-friendly cheeses.

Instructions

It is a very convenient recipe to create a single-serve keto breakfast with the same carbs per serving.

First, you need to prepare the zucchini, peeling then lengthwise with a vegetable peeler, and create a ribbon.

The zucchini ribbons act as the crust. It is the trick to making a single-serve crustless quiche that holds in one hand.

Below, you can see how to arrange the zucchini ribbons in the muffin holes to ensure they are fully covered.

Next, prepare the filling by cooking some grated zucchini along with the pesto.

Finally, combine the cooked zucchini with egg almond milk batter and filled each hole with the filling.

Storage Instructions

It is better to serve these crustless zucchini quiche hot. However, you can also store leftovers in the fridge for up to 3 days or freeze them in an airtight container.

To rewarm your crustless zucchini quiche, you can:

  • Pop them in the microwave for 1 minute – not the best as the egg texture gets a bit chewy, but if you are at work, it is a way to do it!
  • Bake them at 250°F (120°C) for 10-12 minutes until warm in the center.

Ingredients

Pesto Zucchini mixture

Quiche Egg and Cheese Pesto Filling

For the muffin tins preparation

  • 1 Zucchini peeled into ribbons
  • 1 teaspoon Coconut Oil or vegetable oil of your choice (to grease the muffin tins)

Instructions

  • Preheat the oven to 400°F (200°C).

For the muffin tins preparation

  • With a vegetable peeler, peel one zucchini into thin ribbons. Make sure you trimmed the ends of the zucchini first. Don't peel the other zucchinis. 
  • Grease a 6-hole jumbo muffin tray with a bit of coconut oil and arrange the thin zucchini ribbons all around the muffin tin, including the bottom, to create a crust-like style. Repeat for each muffin hole until the tray is full. Set aside.

Pesto Zucchini Mixture

  • Grate fresh zucchinis into 3 cups of grated zucchini. I used a manual grater but you can use a food processor with the right attachment.
  • Squeeze out the excess water with your hand and discard the zucchini water or reuse it in another recipe.
  • In a saucepan warm olive oil and add chopped brown onion and grated zucchini. Fry under medium heat until fragrant and no more liquid appears in the pan. It should not take more than 5 minutes. Stir in 2 tablespoons of pesto into the cooked zucchini.
  • Cool down for 15 minutes in a bowl before using.

Quiche Egg and Cheese Pesto Filling

  • Meanwhile, in a large mixing bowl, whisk the eggs, milk, oregano, pesto, and grated Parmesan. Adjust salt and pepper to your taste.
  • Combine the cooked pesto zucchini mixture into the egg mixture and use the mixture to fill each prepared muffin tin. I used about a cup per muffin case. It depends on the size of muffin tins you use, of course. Mine are jumbo size.
  • Bake for 35-45 minutes or until a pick inserted in the middle comes out clean.
  • Carefully remove from the muffin tray. Place a cookie rack on top of the muffin tray and flip it over. All the crustless quiche will come out together and it should not break using this technique.
  • Eat hot or cold.
  • Store in the fridge for up to 3 days, on a plate covered with foil to prevent the quiche from drying out.
Freezing: You can freeze the cooked Crustless zucchini quiche too. Wait until cool and freeze in an airtight plastic box, leaving half thumb space between each quiche. Don’t overlap them or separate them with a piece of parchment paper – easier to defrost later on. Defrost the day before you intend to eat and rewarm in the oven or microwave few minutes.
Cheese: you can also replace parmesan with grated cheddar, Edam, or mozzarella.

    9 Thoughts On Crustless Zucchini Quiche
    • No I don’t but all pesto at the store are keto approved, it contains only basil leaves, pine nuts, salt, garlic and parmesan. Enjoy the recipe, XOXO Carine

  1. 5 stars
    You might want to add under the “For the muffin tins preparation” section that you used a LARGE size muffin tin. Using regular size muffin tins changes the yield. I also chose to swap a cup of Parmesan cheese with sharp cheddar cheese and added chopped bacon to the egg mixture. Tastes Great!

    • I would say it makes one 10 inches (26cm) quiche. I am not too sure as I always make mine in my muffin tins for on the go breakfast. Enjoy the recipes on the blog! XOXO Carine.

    • Great! thanks for sharing your positive experience with this recipe. I just updated the recipe with the nutrition facts 🙂 Enjoy the blog. xoxo Carine.

    Are you able to grow zucchini where you are? I’m a terrible gardener–the only thing I have ever been able to grow is zucchini. It grows despite my terrible gardening skills. Just a thought from an old lady.

    • I am a terrible gardener too. I tried cherry tomatoes, capsicum and lemon and I never get anything great. I should try zucchini for my next attempt if you say it is easy to grow 🙂 It is so expensive in NZ during winter but still one of my fav veggie!
