Ingredient Notes

Labeled ingredients needed to make a crustless spinach quiche recipe.
  • Oil: Prepping the dish with olive oil helps the quiche remove easily and perfectly sautes the yummy onion. 
  • Onion: Half a medium yellow onion adds some sweetness to the recipe.
  • Garlic: Minced garlic adds an oh-so-subtle spice and loads of flavor.
  • Spinach: Adding fresh spinach, properly washed and chopped, is an excellent way to add nutritional value to your morning meal.
  • Basil: Basil adds a sweet freshness to the cheesy quiche.
  • Salt and pepper: Salt and black pepper balance the flavors.
  • Large eggs: Eggs hold all the delicious ingredients together with a fluffy and creamy texture.
  • Milk: I like to use whole milk because it is lighter than the often-used heavy cream.
  • Cheese: Shredded Colby Jack or Monterey Jack cheese adds a creamy and tangy flavor, really elevating this recipe!

Variations and Substitutions

  • More Veggies: This is a great recipe for adding pretty much whatever you have on hand, like fresh mushrooms, juicy tomatoes, red pepper, and more.
  • Fresh Herbs: Thyme, oregano, chives, rosemary, and dill are delicious herbs to add to your savory quiche recipe. 
  • Protein: Add protein, like chopped bacon, diced ham, or savory breakfast sausage.
  • Other Cheeses: Use your favorite cheese or a combination of a few, like goat cheese, gruyere cheese, feta, cheddar cheese, swiss cheese, or parmesan cheese. 
  • French Style Quiche: Replace the milk with heavy cream for a rich and decadent French Quiche.

Tips

  • Fresh is Best- Go ahead and get the fresh spinach for the best results.
  • Hot or Cold– You can enjoy quiche hot or cold. Serve it fresh from the oven or make it a quick meal to-go straight from the fridge made the night before.
  • Let it Rest- Don’t skip the resting time. It makes the quiche come out in nice slices easily!

How to Make Easy Crustless Quiche with Spinach

Be sure to see the recipe card below for exact ingredients and full recipe instructions!

Step 1 | Prep and saute onions

Let’s begin by preheating the oven to 350℉ and greasing a 9-inch pie plate with oil or cooking spray.

Then, in a large skillet, warm the oil and add the sweet onion, cooking until it is translucent and starts to brown. This should take about 7-8 minutes.

Then, stir in the chopped spinach in batches and cook until wilted. After, remove the pan from the heat and set it aside.

Recipe FAQs

Why is my spinach quiche watery?

Watery quiche is not uncommon because spinach releases excess moisture while cooking. But as long as you cook it long enough and bake it at the right time, it should have a perfect texture. If the quiche is too watery, increase the bake time by a few extra minutes.

Do you cover a quiche when baking?

You can cover the quiche as it bakes if desired. Especially if the quiche has a crust, the aluminum foil will help keep the crust from burning.

Can you make crustless spinach quiche ahead of time?

Absolutely! Make it ahead and store it properly to be served at a later time. You can reheat it in the microwave or until warmed through in a preheated oven at 350°F.

Storage

Refrigerate: This crustless spinach quiche stores well in an airtight container in the refrigerator for up to 4 days. Just make sure it cools to room temperature first.

Reheat the leftovers in the oven or microwave, or enjoy it cold!

Make ahead: Make this quiche a day ahead of time, store it in the fridge (covered with plastic wrap or a lid), and then bake it just before you’re ready to eat!

Freeze for Long-term Storage: Once it cools completely, you can also freeze the quiche. Wrap it in plastic wrap and aluminum foil. It will last in the freezer for up to three months. Before serving again, let it thaw in the fridge overnight or bake it longer.
