Ingredients for Crustless Spinach Quiche

2 tablespoons mild-tasting oil – I like using vegetable or canola oil for a neutral flavor.
2 cups onion, chopped – This forms the savory base.
2 garlic cloves, minced – For that irresistible aromatic kick.
10 ounces fresh spinach – Make sure it’s fresh for the best texture and flavor!
1 teaspoon kosher salt, divided – Essential for bringing out all the flavors.
1/4 teaspoon crushed red pepper flakes – Just a pinch for a hint of warmth.
6 large eggs – The binder that holds our delicious spinach quiche no crust together.
1/4 cup heavy cream – This makes the quiche rich and creamy.
1 1/2 cups shredded mozzarella cheese – Melty cheese is key for a delightful crustless quiche with spinach and cheese.

How to Make Crustless Spinach Quiche

Learning how to make crustless spinach quiche is simpler than you might think, and the results are so rewarding. This recipe is designed to be straightforward, letting the fresh ingredients shine.

Step 1: Preheat your oven to 375°F (190°C). Take a moment to properly grease your 9-inch pie pan. This ensures your beautiful quiche slides right out.
Step 2: Heat 2 tablespoons mild-tasting oil in a large skillet over medium heat. Add your chopped onion and cook until it becomes beautifully translucent, which usually takes about 8 minutes. The sweet aroma will start to fill your kitchen!
Step 3: Toss in the minced garlic and sauté for just 1-2 minutes until it’s wonderfully fragrant. Be careful not to burn it!
Step 4: Now, gradually add the fresh spinach in batches. Let each addition wilt down and release its liquid before adding more. Stir in 1/2 teaspoon kosher salt and the crushed red pepper flakes. Once wilted, remove the skillet from the heat and let the spinach mixture cool slightly. This step is crucial for a perfectly cooked spinach quiche without pie crust.
Step 5: In a large bowl, whisk together the 6 large eggs, 1/4 cup heavy cream, and the remaining 1/2 teaspoon kosher salt. Whisk until everything is well combined and looks smooth.
Step 6: Stir in the 1 1/2 cups shredded mozzarella cheese and the cooled spinach and onion mixture. Mix everything gently until it’s all incorporated. This is where the magic happens for our crustless spinach quiche recipe.
Step 7: Pour the delicious egg and spinach mixture into your prepared pie pan. Spread it out evenly.
Step 8: Bake for 20-25 minutes, or until the edges are lightly browned and the center is set. You’ll know it’s ready when it jiggles just a little in the middle.
Step 9: Let your amazing crustless spinach quiche cool for about 10 minutes before slicing and serving. This resting time is important for the quiche to firm up perfectly.
