This crustless quiche with spinach is an easy recipe that’s perfect for brunch! The savory flavor will impress everyone.

Crustless Quiche

Looking for a savory brunch recipe to impress? Try a crustless quiche! This concept is our favorite for entertaining: it’s deliciously savory and hearty, with lots of protein to keep bellies full all morning. Even better: it’s so easy to whip up! No need to bother with a quiche crust: just whisk together the filling and pop it in the oven. This crustless spinach quiche is a bit of a miracle: even our spinach-fearing 4 year old loves it! Here’s how to make a crustless quiche recipe and how to customize the filling for your family.

Elements in a crustless quiche

A crustless quiche is a savory egg custard that’s baked without the traditional pastry shell. Without the crust, a crustless quiche is similar to an Italian frittata. The difference? Quiche traditionally has more dairy than a frittata. Here’s what you’ll need for the base recipe of this crustless spinach quiche. The great thing about this recipe is that it convinces even the spinach-averse (like our son!). But you can customize it to have whatever vegetables you choose. Here’s what you’ll need:

  • Eggs
  • Oregano, garlic powder, salt and pepper
  • Frozen spinach
  • Cottage cheese: often a quiche recipe uses whole milk, but cottage cheese makes magic here! It brings a bold, savory flavor and velvety texture
  • Parmesan cheese
  • Jarred roasted red peppers

Some notes on the spinach

This recipe is so simple: all you have to do is mix up the ingredients and bake it up for 25 minutes until puffed and golden! How does it all work? Here are a few notes on some of the ingredients and how they make the magic:

  • Use frozen spinach, not fresh. Why? Frozen spinach has already been blanched so it has reduced greatly in volume versus fresh spinach. It also has a chewy, desirable texture: it’s hard to describe, but trust us! Think spinach artichoke dip.
  • Thaw the spinach under warm water. Simply place it in a colander and warm it under water! However, we’ve noticed that some spinach brands are frozen solid into blocks: you may need to use a microwave to thaw in that case.
  • Important: squeeze out as much water as possible! This prevents a watery crustless quiche. Use your hands to squeeze it out while the spinach is in the colander. The spinach should feel like dry crumbles when you are done.

Variations on mix-ins

You can turn this crustless quiche recipe into hundreds of different flavor variations based on your preferences! If you’d like, you can add other flavors to this one like a handful of chopped ham or crumbled bacon. Or, you can drop the spinach and use other cooked vegetables. Add ½ cup additional mix-ins to the recipe below, or remove the spinach entirely and substitute about 1 to 1 ½ cups mix-ins. Here are some ideas (make sure they are finely chopped):

As a note, you’ll want the veggies on the done side when you sauté them, so they don’t release too much moisture while baking. They should be finely chopped for good distribution.

Description

This crustless quiche with spinach is an easy recipe that’s perfect for brunch! The savory flavor will impress everyone.


Ingredients

Scale
  • 10 to 12 ounces frozen spinach*
  • 6 large eggs
  • ½ teaspoon dried oregano
  • ½ teaspoon kosher salt
  • ¼ teaspoon garlic powder
  • 1 cup cottage cheese
  • ¼ cup grated Parmesan cheese
  • ¼ cup chopped roasted red pepper (from a jar), plus more for topping
  • Fresh ground black pepper

Instructions

  1. Preheat oven to 375°F. Grease a 9” round pie dish.
  2. Place the spinach in a colander and let warm water run over it until it is thawed, about 1 minute (some brands take a bit more effort to defrost: you can also use a microwave if necessary). Then use your hands to squeeze out as much excess liquid as you can.
  3. In a large bowl, whisk the eggs. Then stir in the oregano, salt, garlic powder, cottage cheese, grated Parmesan cheese, spinach, and roasted red pepper. Add a few grinds of fresh ground black pepper if you like.
  4. Pour the egg mixture into the prepared pie dish. Sprinkle the top with a few tablespoons of additional chopped roasted red pepper.
  5. Bake the quiche for 25 to 30 minutes, until set in the center and golden around the edges. Allow to rest for at least 15 minutes before serving. (Storage info: This saves well! Store refrigerated for up to 5 days: you can eat it cold, room temp, or re-warm it. Try it in a sandwich!)

Notes

*Note: To customize the mix-ins in this recipe, substitute about 1 to 1 ½ cups mix-ins for the spinach. Try finely chopped sauteed broccoli, ham or bacon, caramelized onions, roasted peppers and onions or sautéed peppers, sauteed mushrooms, and so forth. You’ll want the veggies on the done side when you saute them, so they don’t release too much moisture while baking.

  1. This was delicious and so easy to make. It was perfect for a weeknight dinner. I will definitely be making this again.

  2. Do you think it would work well to mix ingredients together the night before and just pour it in the pie plate to bake in the morning?

    1. You can likely freeze leftovers — though we haven’t tested it! Store in a freezer safe container for a month or two. We’d probably let it thaw in the refrigerator to defrost. Let us know how it goes!

  3. I have enjoyed every recipe on your site that I have made. You two have wonderful tips too. I really appreciate you ! I had a friend purchase your cookbook for me, while she was getting herself a copy. She is a food scientist and works for a well known food company. She introduced me to your site too.
    Thanks

    1. I am a recent newbie to making quiche however I luv adding shredded carrots, zucchini & parsnips. Always use fresh vegs & serve w/ either marinara sauce or medium-hot salsa (especially the pineapple ones!)
      & pls use only ground white pepper on these delicate flavors.
