Crustless Spinach Quiche

Don’t let the title fool you, crustless spinach quiche is every bit as decedent and delicious as it’s carb filled predecessor—only without the crust there’s more room for the creamy, cheesy low carb foods we love!

Every delectable bite of this quick crustless quiche is filled with the perfect amount of cheese and veggies, to help you feel a little less guilty. It goes down well with a cup of coffee or tea—heck, even a glass of wine if you’re doing breakfast for dinner!

I’ll share all my favorite ways to make this recipe; from crustless to crust—from mini quiche, to full size so you can decide which of the low carb recipes you’d like to go with.

Let’s get this quiche party started!

Cutting into the crustless spinach quiche Ingredients for Crustless Spinach Quiche; eggs and onions

Crustless quiche Ingredients

As you know, at the core of every basic crustless quiche recipe, there eggs. The rest of the ingredients are more flexible, and can be swapped around according to what you’re looking for:


Low Carb Vegetables

The most important part when using low carb vegetables in any quiche recipe is to cook them before adding them to the quiche. This allows them to release their liquid—crust or no crust, a soggy quiche is never a good thing!

For this crustless spinach quiche, I opted for (duh) spinach and onions. Feel free to mix, skip or swap the veggies according to your low carb food list—just be sure to keep the ratio of vegetables to eggs the same as I did here.

Crustless spinach mushroom quiche? Use less spinach to lieu of the mushrooms. Delish!

Low Carb Milk

Traditional quiche calls for cow’s milk—which isn’t a low carb shopping ingredient due to its high sugar and carb content. A low carb milk alternative will do the trick for this recipe—use unsweetened almond or coconut milk for a lower fat healthy crustless spinach quiche recipe.

Or do as I did, and opt for heavy cream! With hardly any carbs in cream, you’ll get a lot of creamy taste and texture for your buck!

Carbs in Cheese

Since there are very few carbs in cheese, it’s easy to find a low carb cheese for this recipe. I love mozzarella—it’s neutral, tasty, and works well with the other ingredients. Feel free to use whatever you have on hand. A crustless spinach feta quiche would be marvelous!

How to Make Spinach bacon quiche Using this recipe

In attempt to make more low carb vegetarian recipes, I didn’t add bacon to this crustless spinach quiche.

However, for us meat eaters, it’s a fact: bacon makes everything taste better.

The only additional requirement for making a spinach bacon quiche is to cook the bacon before adding it to the quiche, and dab off the surface grease (again, the less liquid we bring into the quiche, the better). Chop your bacon into desired bite-sized bits and that’s all!

Bonus points if you cook the veggies in the pan’s bacon fat in lieu of vegetable oil—it’ll make this crustless spinach and bacon quiche next level good! Or, for the less healthy option, skip the greens and go for a crustless bacon quiche.


Crustless quiche recipe Tips

The main tip to making a crustless quiche recipe that your family will cherish for years, is to cook the ingredients before adding them to the pan. I know I’ve said this before, but it makes such a difference in the consistency of the dish!

Another important tip—when making crustless quiche vs. quiche with a crust, you’ll want to use a pie pan, NOT a quiche or tart pan. It may seem silly I’m even mentioning this, but I’ve seen one too many recipe flops to not warn you guys.

If you have no idea what I’m talking about, a quiche/tart pan is made with a removable base so you can more easily pull you finish goods out of the pan. Well, when you don’t have a low carb quiche crust to protect the insides, you’ll get one, big ole mess.

  1. Marcie Correa

    I am preparing and freezing many meals for when I will be laid up for a few weeks and being tended to by my sister. Is this crustless quiche a candidate for this?

    • Lindsey

      Hi Marcie! YES! This is the perfect recipe for meal prep! I bake mine, cut it into slices and freeze in individual baggies. In fact, I just left for a work trip and wanted to leave some meal prep for my boyfriend, so I doubled the recipe and baked it in a casserole dish. (Bake time will vary, I believe I doubled it?) He had food for the entire workweek, plus a few frozen slices left over! Report back and let me know what you think, hope you enjoy! (and SO sorry to hear you’ll be laid up, wishing you a fast and easy recovery :))

      Thanks Beth!! Hope you enjoy as much as I do, I can’t get enough <3

  3. Kym

    before you mix the spinach with the eggs, do you have to drain the excess liquid?

    • Gritchen Vinas

      Hi Kym! When you cook the spinach it releases the excess liquid 🙂 Hope you enjoy!
