Let’s dive into the full recipe and explore how to make this spinach quiche with ease!

Ingredients You’ll Need

Here’s the full list of ingredients for this healthy crustless quiche:

  • 2 tsp extra virgin olive oil
  • 1 medium yellow onion or sweet onion, finely chopped
  • 10 oz package frozen chopped spinach, thawed and drained
  • 12 oz grated Cabot 50% light cheddar cheese
  • 8 large egg whites (or 1 ½ cups liquid egg whites in a carton)
  • 1 whole egg
  • 1/3 cup low-fat cottage cheese
  • 1/4 tsp ground cayenne red pepper
  • 1/8 tsp sea salt
  • 1/8 tsp ground nutmeg
  • 1/4 tsp ground black pepper

These ingredients come together to create a flavorful, low-calorie breakfast that feels indulgent without being heavy. If you’re looking for something lighter, using low-fat cheese and egg whites keeps the quiche nutritious and light, without sacrificing flavor.

Step-by-Step Instructions to Make Crustless Spinach Quiche

Making this crustless quiche is incredibly easy and takes very little prep time. Follow these simple steps to create your own:

Step 1: Preheat the Oven and Prepare the Pan

Preheat your oven to 375°F (190°C). While the oven is warming up, lightly coat a 9-inch nonstick pie pan with olive oil cooking spray to prevent the quiche from sticking.

Step 2: Cook the Onion and Spinach

In a nonstick skillet, drizzle the olive oil over medium-high heat. Add the chopped onion and cook it for about 5 minutes or until translucent. Next, add the thawed and drained spinach to the skillet. Stir it for 3 minutes until the spinach is completely dry. This step is important to remove any excess moisture from the spinach, which can make the quiche soggy.

Step 3: Layer the Cheese and Spinach Mixture

Once the spinach is ready, sprinkle the grated cheddar cheese in the bottom of the prepared pie pan. Then, top it with the cooked spinach and onion mixture. This gives the quiche a great base of cheese and spinach flavor.

Step 4: Whisk the Egg Mixture

In a medium bowl, whisk together the egg whites, whole egg, cottage cheese, cayenne red pepper, sea salt, nutmeg, and black pepper. The cottage cheese adds creaminess to the quiche, while the cayenne pepper provides a subtle heat that complements the other flavors perfectly.

Step 5: Pour and Bake

Pour the egg mixture evenly over the spinach and cheese layers. Bake in the preheated oven for 40-45 minutes, or until the quiche is set and lightly browned on top. You can check if it’s done by inserting a knife into the center; if it comes out clean, the quiche is ready.

Step 6: Let It Sit and Slice

Once the quiche is baked, remove it from the oven and let it sit for 5 minutes. This allows the quiche to set properly and makes it easier to slice into wedges. Serve warm and enjoy!

Why Crustless Spinach Quiche Is Perfect for Healthy Eating

One of the biggest benefits of this crustless quiche is that it’s a low-carb, healthy breakfast option. Without the crust, it’s much lighter and much lower in calories, which makes it a great choice for those looking to reduce carbs or follow a low-calorie diet.

Additionally, this quiche is full of protein and fiber, making it a satisfying meal that can keep you feeling full for hours. The spinach adds a great dose of vitamins and minerals, while the cottage cheese provides additional creaminess without the fat of traditional cream.

For those looking for even more healthy breakfast ideas, try pairing this quiche with a refreshing side of fruit or a simple kale Caesar pasta salad for a well-rounded meal.

Customizing Your Crustless Spinach Quiche

This spinach quiche recipe is highly customizable, so you can tailor it to your tastes or dietary needs. Here are a few ideas:

  • Add More Veggies: Feel free to mix in some chopped tomatoes, bell peppers, or mushrooms for extra flavor and nutrition.
  • Use Different Cheeses: While Cheddar adds a sharp, creamy taste, you can swap it out for other cheeses like mozzarella, feta, or goat cheese for a different flavor profile.
  • Make It Spicy: If you love heat, you can increase the amount of cayenne pepper or even add some diced jalapeños to the spinach mixture.
  • Switch Up the Proteins: Add some cooked bacon or sausage if you want to make it heartier or if you enjoy a bit of meat in your quiche.
  • Make It Dairy-Free: If you want a dairy-free version, swap the cottage cheese for a dairy-free alternative like vegan cream cheese, and use a plant-based cheese.

You can also prepare the quiche the night before and bake it in the morning, making it a perfect make-ahead breakfast or brunch option.

Serving Suggestions for Crustless Spinach Quiche

This quiche is versatile enough to pair with a wide variety of other dishes, whether you’re serving it for breakfast, brunch, or a light lunch. Here are some ideas for what to serve alongside:

  • Salads: Serve your quiche with a simple side salad like cranberry and brie flatbread or a fennel apple salad for a refreshing contrast to the savory quiche.
  • Fruit: A fresh fruit salad with berries, citrus, or melons adds a touch of sweetness and freshness to balance out the richness of the quiche.
  • Smoothies: Pair the quiche with a nutrient-packed smoothie, like banana cream pie overnight oats or a tropical fruit blend, for a complete breakfast experience.
  • Breakfast Sides: Complement the quiche with crispy bacon or a hearty savory bacon Dutch baby for an indulgent brunch.

Storing and Reheating Your Crustless Spinach Quiche

If you have leftovers, storing and reheating your quiche is easy:

  • Refrigerate: Keep leftovers in an airtight container in the fridge for up to 3 days.
  • Reheat: You can reheat individual slices in the microwave or warm the entire quiche in a 350°F oven for about 10-15 minutes.
