What I Love About This Crustless Spinach Quiche Recipe

While incredibly good-looking, this crustless spinach quiche is more than just a pretty dish!

  • It comes together in under an hour (and most of that is hands free baking time!!)
  • Utilizes ingredients that you’ll almost always have on hand
  • It’s easy to customize if you have a craving or some leftover veggies you want to use up

Recipe Notes

This dish is easy as pie (or quiche, ha!). Make this crustless spinach quiche just once and you’ll find that quiches are a great meal for any occasion!!

Ingredient Notes

Spinach: this recipe works best as a fresh spinach quiche. If you want to use frozen spinach, make sure to thaw and remove the water before adding it to the dish.

Heavy cream: Make sure you get heavy cream or heavy whipping cream for this dish, it whips up nice and thick to give it that velvety texture. In a pinch, you can also use equal parts low carb greek yogurt and milk.

Tools to Make

The only special tool you’ll need for this dish is a pie pan. You can get recyclable aluminum ones, or reusable metal or glass ones.

Don’t try making this dish in a quiche/tart pan! The removable bottom doesn’t work with crustless quiche recipes.

Storing Tips

This crustless spinach quiche makes 8 servings, so unless you’re serving a big crew, you’ll probably have some left over.

I move my quiche to an airtight container and keep it in the fridge. When ready to eat, I reheat it in the microwave at 50% power for 1-2 minutes (check your microwave) but one of the most amazing things about quiche is that its absolutely DELICIOUS cold.Chopped veggies for crustless spinach quiche

Can You Freeze This?

Freeze this crustless spinach quiche after baking by slicing it up, popping it onto a tray and freezing it. Once frozen, move it to a freezer bag for long term (up to 3 months). I like to freeze individual slices for portioned out freezer meals.

Reheat the quiche from frozen by baking it on a tray for 25 minutes at 350 degrees.

Meal Prepping Tips

This easy spinach quiche is great for meal prepping. I keep it portioned out in the fridge, and I have 8 meals ready to go!

This quick crustless quiche can also be baked and frozen as a whole or in slices, for low carb meals on hand at a moments notice!Crustless spinach quiche in a pie pan

Crustless Quiche Recipe Variations

This crustless quiche is endlessly customizable. I love adding all sorts of low carb veggies and seasonings for lots of different healthy and delicious low carb meal options.

Can I Add Broccoli?

One of things about the cheesy goodness that is quiche is that it makes a great backdrop for all sorts of vegetables! If you run out of spinach, try out this crustless broccoli quiche for a healthy quiche that’s loaded with creamy deliciousness AND high in vitamin K and potassium! Win!

Can I Add Asparagus?

For another fun spin on this low carb dish, serve up this crustless asparagus quiche! The crunchy, slight-sweetness of the asparagus is amazing against the salty cheese and makes for a nutrient packed, low carb meal, for breakfast, lunch or whenever!

How Can I Add Meat?

This crustless spinach quiche is super duper decadent, but when I really want to amp up the wow factor, I go for a crustless quiche lorraine. Take all the velvety flavors of quiche, add in some salty bacon and warm nutmeg, and VOILA!

This variation is unforgettable and is one I make over and over again!

Can I Make Smaller Portions?

The serving guidelines for this crustless spinach quiche are as follows: slice into 8 slices, and 1 slice = 1 serving.

If you just don’t need the extra seven slices, or don’t want to be tempted by having them around, ( I FEEL you, friend), then make a crustless mini quiche! Serving is one and done, or make a few and freeze them for another time.

Crustless Spinach Quiche

Rich and creamy, with touches of onion and garlic and salty mozzarella... this crustless quiche is one of those low carb recipes that I completely forget is low carb.
Prep Time25 mins

Total Time50 mins
Servings: 8 Slices

Ingredients

  • 2 Tablespoons Vegetable Oil
  • 2 Cups Onion chopped
  • 2 Garlic Cloves minced
  • 10 Ounces Spinach fresh
  • 1 Teaspoon Salt

  • 6 Large Eggs
  • 1/4 Cup Heavy Cream

Instructions

  • In a large skillet, heat the oil on medium. Add chopped onion and cook until softened.
  • Add garlic, and cook for an additional minute—stirring constantly.
  • Add spinach to skillet. You may need to do this in batches depending on your pan size; when the spinach releases water, there’ll be more room in your skillet. Turn spinach using tongs until all of it is wilted.
  • Add 1/2 teaspoon salt and crushed red pepper.
  • Place veggies evenly into the prepared pan.
  • In a large bowl, whisk together the eggs heavy cream and remaining salt until combined. Stir in the mozzarella.
  • Make sure the veggies in the prepared pan aren’t too hot. Then pour the contents of bowl into the pie dish over veggies.
  • Bake quiche for 20-25 minutes. The quiche is done when the edges begin to brown and the center is firm.
  • Allow the quiche to cool for 10 minutes before cutting and enjoy!

Notes

Nutritional information is based on 1 slice, if you slice this quiche into 8 slices.
 
You can swap the fresh for 10 oz frozen spinach --  Just be sure to thaw and thoroughly drain the spinach before adding it in (you want to remove as much liquid as possible).

  1. 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?

    Reply

    • 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 :))

    • Hi Shaylene!😊 The nutritional information is based on 1 slice, if you slice this quiche into 8 slices. Hope you enjoy 😊

  5. Your re ope looks yummy. If I want to use frozen spinach instead of fresh, is that doable? If so, how much frozen spinach would I use to equal the 10 oz of fresh spinach in your recipe.
    Looking forward to your reply!

    • Hi D! Yes, you can definitely use frozen spinach 🙂 Just be sure to thaw and thoroughly drain the spinach before adding it in (you want to remove as much liquid as possible). You’d use 10oz of frozen spinach.:)

  6. Made multiple of this recipe for a large group (with the help of LB) for a post-wedding breakfast. It got RAVE reviews from everyone who tried it. Very easy to make and very impressive for guests!

  7. Delicious! My daughter (17) loved this as much as I did. I have a co-worker who raises chickens, so the eggs were extra fresh! Great recipe!

  9. Have you ever tried this with Swiss cheese? I have a spicace quiche recipe that calls for Swiss and it gives it a distinct flavor. Was wondering if I could substitute Swiss for mozzarella?

    Reply

  11. Great recipe- the only issue I had was with the baking time. By 25 minutes, the center was not firm yet. I had to put the quiche back in the oven on 350 for another 5- 7 minutes. Otherwise it was great

    Reply

    • The longer bake time is totally fine, you want the center to be completely set before pulling it out, 🙂 so I’m happy you continued to cook it. I’m glad you enjoy!!! 🙂 <3
