This Crustless Spinach Quiche is the perfect light breakfast! It is only 140 calories per slice. With only 20 minutes of hands on time you just can’t beat this spinach quiche recipe. It is my Crustless Vegetable Quiche recipe reimagined into a delicious spinach mushroom quiche that will always have brunch guests asking you for the recipe.

Serve it with my amazing Bloody Mary Mix, my irresistible homemade granola recipe, and of course make a batch of my apple carrot zucchini muffins to go with it.

Almost two years ago now I made you this Crustless Vegetable Quiche Recipe. The recipe development happened to come at the same time as I was talking to lots of people in my life about grief and how to be there for people who are grieving. I won’t rewrite the post here, you can read it for yourself, but it felt incredibly important to write it. And since then I have had so many people comment about how they found that post at the exact right moment in their own grief journey.

So here I sit with this blog . . . and it’s a business, guys. It pays the bills, it will hopefully put my kids through college. It’s something I dedicate roughly 40 to 80 hours a week to. It’s a job. I’m going back and updating old posts. Writing them in such a way that I hope google will throw me a bone and help them be easier for you to find in the sea of other recipes.

But I refuse to touch that post. I have tried to go back and update that quiche recipe with the right keywords, and I just can’t. It seems too important to leave it as it is. So go read that post. Maybe it will help someone you know in your life. And then make this spinach quiche recipe from scratch, and the original too, because they both are so good. 


  • It’s easy! If you can sauté vegetables, you can make this quiche.
  • It doesn’t have a crust. This makes it easier, and fewer calories. A double win for me.
  • It’s low carb. That’s not something I’m paying a lot of attention to, but if you are, this baby only has 5 grams of carbohydrates per slice!
  • It uses fresh spinach! 
  • It’s easy to customize! More on that in a minute.

I love my crustless quiche recipes because they are so simple. They are basically three simple steps and once you get it down, you can mix up the ingredients.

  1. Sauté all of the vegetables.
  2. Mix together the eggs, milk, spices, and cheese.
  3. Pour all the vegetables into the quiche pan and then top it with the egg mixture.

So simple, right?

This spinach mushroom quiche comes together with minimal ingredients, which is another reason why I love it!

  • extra virgin olive oil
  • minced garlic
  • onion
  • mushrooms
  • spinach
  • eggs and egg whites
  • milk
  • swiss cheese
  • salt and pepper


Love this but want to mix it up a little?

  • Add some bacon before you start sautéing the veggies for a bacon spinach quiche.
  • Poor these in muffin tins (get tips from my Ham and Cheese Egg Muffin post) for mini spinach quiches.
  • Not in love with mushrooms? Leave them out and throw in some red peppers instead!

Absolutely! If you don’t love Swiss Cheese, pick something that you do love. This would be amazing as a spinach feta quiche. I struggle not putting feta on absolutely everything, so I skipped it this time. (See my Roasted Beet Salad or my Greek Salad Quinoa Bowls for good examples.)  Mozzarella would be another great option in this spinach and cheese quiche.

This is such a great recipe if you are cooking for a crowd. It is simple and can be served warm or cold. Plus it is a great vegetarian option. If you are hosting and want more great brunch recipes that would pair well with this try:

Total: 20 minutes
This Crustless Spinach Quiche is the perfect light breakfast! It is only 140 calories per slice. With only 20 minutes of hands on time you just can't beat this spinach quiche recipe.


  • 1 tablespoon extra virgin olive oil
  • 2 garlic cloves minced
  • 1/2 yellow onion diced small
  • 8 ounces mini portabella mushrooms sliced (white mushrooms could also be used)
  • 5 cups spinach
  • 4 large eggs
  • 4 egg whites
  • 3/4 cup swiss cheese
  • 3/4 cup milk (I used skim)
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper


  • Preheat the oven to 350 degrees. Spray a nine inch quiche dish with cooking spray and set aside.
  • In a large skillet, heat the olive oil. Then add the garlic, onion, and mushrooms. Cook, sautéing until the mushrooms are soft. About 5 minutes.
  • Add in the spinach and stir until wilted. About two minutes. Remove from the heat and set aside.
  • In a large bowl whisk together the eggs, egg whites, milk, salt, pepper, and cheese.
  • Pour the vegetables into the quiche dish.  Add the egg mixture over the top.  Bake for 40 minutes or until the edges start to pull away from the side of the dish and the middle has just a slight jiggle to it.

    Thanks for pointing us towards that grief post. I lost 3 people last year (all 3 of them young or young-ish), and this year I’m already having people around me lose people they love.

    I love this phrase from your post: “bearing witness.” It’s like the Buddhist idea of the “broken open heart”–once you have it, you can truly understand and love all the other people who also have broken open hearts.

    I will also do my best to remember the phrase of grief being a debt that has to be paid, either now or later. It’s a super helpful concept!

    Where do I find the griefpost. I just lost my mom 3 weeks ago. Thank you.

    • Lisa Longley says

      I am so so sorry Lori. It is this one.

    Is the nutrition information for one serving?

    • Lisa Longley says

      Yes, or 1/8 of the total quiche.

  4. Anna says

    Can this be made with unsweetened almond milk?

    • Lisa Longley says

      I haven’t tried that, but I think it would work just fine.

  5. Maudie says

    Thank you first for your crustless quiche recipe which I’ll be making very shortly for a neighbor and secondly for your Grief Post. Your advice is invaluable, I lost my husband three years ago and at times his loss is as fresh and raw today as it was three years ago. One of the greatest gifts you can give a friend is to indeed bear witness!
    Thank you,

    • Lisa Longley says

      Oh Maudie, I know exactly what you mean. It has been 8 years since I lost my son, and sometimes it feels like 8 minutes. I just came across this book and it is the BEST book I’ve read to date on grief. I highly recommend it. And I would pass it onto your support system too. “It’s Okay That You’re Not Okay.”

  6. Jane Ginter says

    I would have loved to see this recipe but the adds kept me from being able to scroll to it!

    • Lisa Longley says

      Hi Jane! Fortunately every post has a “jump to the recipe” button at the top of each post that will take you right to the recipe.

  7. Kathy says

    I’m going to make your quiche for a lunch this week with girlfriends. What would suggest along with it? Fruit? Salad? Muffins?

    • Lisa Longley says

      Hi Kathy! For a lunch, I think that a salad is a great idea to pair with this. I would probably make this Summer Salad or this Easy Arugula Salad. My Zucchini Muffins are seriously good. And if you wanted to make it a fuller lunch, this Greek Quinoa Salad will still keep things healthy but will leave people full.

  8. Molly English-Bowers says

    Can this be frozen? We have backyard hens and are overflowing with eggs. I am looking for creative ways to use the eggs, so freezing makes the most sense.

    • Lisa Longley says

      First of all, I’m so jealous you can have hens in your backyard. That’s awesome. Second, I think this would freeze fine, but I haven’t tried it. I do know that my Ham and Cheese Egg Muffins freeze VERY well.

      • Paula says

        Can this be made ahead of time then bake in morning

        • Lisa Longley says

          I haven’t tried that with this recipe. I think it would work, but it will likely need more time as it will be coming out of the cold refrigerator.

    Fantastic!! Delicious! I did drain the spinach, mushroom, onion, garlic mixture as mine was really watery. Then I added the egg, milk, cheese mixture. Cooked perfect! I would definitely make this again!

    • Lisa Longley says

      I’m so happy that you liked it, Jean!
