Second of all, it’s versatile. This basic crustless quiche recipe is great as it is, but you can use it as a base recipe to create your signature vegetable spinach quiche. In other words, this recipe can easily be altered to suit your specific tastes and the available vegetables.

For example, replace about 1 to 1 ½ cups of spinach with some of these vegetables:

Pro Tip: To prevent your quiche from becoming too moist, cook the vegetables before adding them to the egg mixture.

Although this gluten-free quiche is vegetarian, feel free to add in some:

You can also use any combination of cheeses for this recipe. Gruyère, Swiss, mozzarella, Asiago, cheddar, feta, ricotta, low-fat cottage cheese…all give different but wonderful results. You decide.

In this particular recipe for a spinach quiche, I combined 1½ cups of mozzarella, 1 cup of cheddar, and ½ cup of Ricotta (homemade and well-drained).

The third reason to love this quiche is that the leftovers are great!

So now that I have shared a few reasons why this is the best crustless quiche recipe, let me show you how easy it is to make!

Instructions

The first thing that needs to be done is to cook the vegetables. This will allow the necessary time for them to cool off a little before adding them to the egg and cheese mixture.

• In a large skillet over medium heat, add 1 tablespoon of olive oil and saute 2 cloves of chopped garlic, followed by 1 diced onion.
• Once the onions have softened, add 10 ounces of spinach.
• Once the spinach has cooked down and has lost most of its moisture, set it aside to cool off while the egg and cheese filling is prepared.

Pro Tip: To prevent a soggy quiche, let the moisture evaporate completely from the spinach and onions.

While sauteing the spinach, let’s get started with the egg mixture.

• Whisk 5 eggs together until they become light and frothy.
• Add 3 cups of shredded cheese and combine with the eggs to get a uniform mixture.
• Add 1 tablespoon of freshly chopped Italian parsley, a pinch of nutmeg, ⅛ teaspoon of Kosher salt, and a pinch (or more) of black pepper.Once the sautéed spinach has cooled down, add it to the cheese mixture.
• Combine properly to distribute all of the ingredients evenly.

ProTip:If you have a few extra minutes, shred your own cheese as this will ensure a fresher, preservative-free product -plus it is cheaper!

Pour the mixture into the prepared pie plate and bake in a preheated oven at 350℉ (175 °C) for approximately 30-40 minutes until the center is set.

Pro Tip: Since every oven heats differently, check your quiche 5-10 minutes before the recommended time. Once the top is firm to the touch, your crustless quiche is ready!
