Ingredients for making crustless quiche

  • Eggs: Use eggs that are as fresh as possible, and if you are able, use organic or cage free eggs.
  • Butter: I use Danish Creamery’s Organic Butter with Coconut Oil. It’s an awesome combo of healthy fats your body thrives on – high-quality butter and unrefined coconut oil. This spread is great for sautéing as it allows foods to be cooked at a higher temp than traditional butters.
  • Milk: You can use any kind of milk for this recipe, regular or plant based. For best flavor, I prefer to use 2% dairy milk.
  • Cheese: I like to use gruyere cheese in this quiche as it has a slightly nutty flavor. I prefer to grate my own rather than use pre-shredded, it has a much bolder flavor. Feel free to use any cheese you have on-hand.
  • Vegetables: I used mushrooms, zucchini, red onions and cherry tomatoes, but this works with any vegetables you have.
  • Seasoning: Salt, pepper and a little nutmeg really help to boost the flavors in the crustless quiche.
Ingredients to make the recipe

How to make a crustless quiche

Start by sautéing the vegetables with the Danish Creamery spreadable butter. You can really turn up the temperature and get the vegetables browned without burning them using this combination of butter and coconut oil. Plus, it adds so much more flavor to the vegetables compared to just adding them to the quiche raw.

Be careful not to overcook the vegetables. You want to add some color to them but keep them crisp. I like doing the mushrooms first on their own, and then cooking the other ingredients together. That way the mushrooms don’t get too much moisture on them from the tomatoes and zucchini. To make it quicker, you can sauté everything together.

Now transfer the cooked vegetables to a 9-inch pie dish and add half of the grated cheese. Mix the eggs and milk together and pour over the vegetables. Then top with the remaining cheese.

Finally, your crustless quiche is ready to pop into the oven until it’s cooked through and the edges are set. The edges will start to brown slightly and pull away from the pie dish and that’s another sign that it’s cooked.

Tips for making crustless quiche

  1. Adjust the amount of eggs if you’re using a pre-made crust. The crust will take up some pace in the pie dish, so it’s important to reduce the amount of eggs to 6 for best results.
  2. Cook the vegetables before adding the egg mixture. This ensures that you have cooked out any excess moisture that otherwise could result in a very liquidy quiche.
  3. Don’t over bake the quiche. The center should still jiggle a little bit when you remove it from the oven. Let the quiche sit for 10 minutes before slicing it so that it sets. It will complete cooking while it sets.

  1. Good flavor, but be aware when you make this…mushrooms zucchini and tomato are probably the most water-dense vegetables and will ooze liquid when they cook. My finished quiche was very wet at the bottom, probably from a combo of the extracted liquid and the light mist of cooking spray. After cutting the first slice I tilted the dish and left a wadded paper towel in the empty space to soak up the remainder of the liquid before slicing to freeze for meal prep.

    1. Thank you! That’s a great tip. I recommend cooking the mushrooms first on their own, and then cooking the other ingredients together. That way the mushrooms don’t get too much moisture on them from the tomatoes and zucchini!

  2. Very enjoyable quiche. I used a mix of fresh carrots, zucchini and yellow squash. After 35 minutes my quiche was not all the way cooked. I stirred the quiche and cooked it for 12 more minutes. Then everything was cooked and ready to eat. Thank you for this lovely quiche recipe.

  3. So delicious and easy to make! I made this quiche for lunch and wanted to take a photo but my husband ate half of it before I could! It was also a great way to use some of fresh veggies I had on hand. thanks for the yummy quiche!

  4. Brilliant and super tasty. I used different veggies and stuck some potatoes in there too. Would definitely make it again. Fab with some toast.

  5. I loved this dish and it was DELICIOUS!! I would totally recommend it to anyone that is looking for a scrumptious dish!

  6. It was so easy to make! A very delicious and nutritious dish, we had it for breakfast (today’s portion is already in the oven)! The whole family loved it, only can recommend! Thank you so much!!

  7. I made this with a leftover phyllo dough from my freezer. Followed the recipe but used asparagus instead of zucchini because it’s what I had on hand. Also, added a smidge of parmesean on top. My entire family loved it! Great for brunch! Thank you for the delish recipe.

  8. Looks delicious! Could you bake the quiche in the cast iron skillet used above? Just thinking about keeping it to one pan 🙂
