Ingredients

To make this Easy Crustless Spinach Quiche, you’ll need:

• 6 large eggs
• 1 cup (240ml) whole milk
• 1 cup (240ml) heavy cream (or substitute additional milk for a lighter version)
• 10 oz (283g) frozen spinach, thawed and squeezed dry
• 1½ cups (170g) shredded cheese (Swiss, Gruyère, or cheddar work beautifully)
• 1 medium onion, finely diced (about 1 cup)
• 2 cloves garlic, minced
• 2 tablespoons (30g) butter
• ¼ teaspoon ground nutmeg
• 1 teaspoon salt
• ½ teaspoon black pepper
• ⅛ teaspoon cayenne pepper (optional)

The star ingredient—spinach—provides essential nutrients while imparting a delicate earthiness. For convenience, frozen spinach works perfectly, but fresh spinach (about 1 pound/450g) can be used after sautéing and draining. The combination of milk and cream creates that signature quiche silkiness, while nutmeg enhances the spinach flavor with its subtle warmth.

Pro Tips

Master the Moisture: The secret to a perfect crustless spinach and cheese quiche lies in removing excess moisture from your spinach. After thawing frozen spinach, place it in a clean kitchen towel and squeeze until no more liquid comes out. This prevents a watery quiche and concentrates the spinach flavor. For fresh spinach, sauté until wilted, then press out moisture.

Achieve Silky Texture: For that luxurious, custard-like consistency, warm your dairy ingredients slightly before combining with eggs. This helps them incorporate more evenly and results in a smoother texture. Just be careful not to heat them too much—lukewarm is perfect to avoid scrambling the eggs when mixed.

Enhance Flavor Depth: Don’t skip sautéing the onions until translucent and slightly caramelized. This simple step develops a sweetness that balances the savory elements of your quiche. Adding the garlic for just 30 seconds at the end prevents bitterness from overcooked garlic while still infusing the dish with its aromatic qualities. This flavor foundation elevates your Easy Crustless Spinach Quiche from good to exceptional.

Instructions

Step 1: Prepare Your Ingredients
Preheat your oven to 350°F (175°C) and grease a 9-inch pie dish. Thoroughly squeeze all moisture from your thawed spinach—this is crucial for texture success! Shred your cheese and set aside. The preparation phase sets you up for a smooth cooking experience, so don’t rush this important foundation.

Step 2: Sauté Aromatics
Melt butter in a skillet over medium heat. Add diced onions and cook for 5-7 minutes until soft and translucent with slightly golden edges. Add minced garlic and cook for just 30 seconds until fragrant. The aroma filling your kitchen at this stage offers a preview of the deliciousness to come!

Step 3: Create Your Egg Mixture
In a large bowl, whisk eggs until well combined. Gradually add milk and cream while continuing to whisk. Season with salt, pepper, nutmeg, and cayenne if using. This base will become the silky custard that holds your quiche together.

Step 4: Combine Components
Fold the cooled onion-garlic mixture and well-drained spinach into your egg mixture. Add 1¼ cups of the shredded cheese, reserving ¼ cup for topping. Stir gently to distribute ingredients evenly. Your mixture should look substantial with a good balance of spinach and egg.

Step 5: Bake to Perfection
Pour the mixture into your prepared pie dish and sprinkle with the remaining cheese. Bake for 45-50 minutes until the center is just set with a slight wobble and the top is golden brown. Let your Easy Crustless Spinach Quiche rest for 10 minutes before slicing—this allows it to set completely for perfect slices. You’ll know it’s done when a knife inserted near the center comes out clean.

Variations

Mediterranean Twist: Transform your Easy Crustless Spinach Quiche into a Mediterranean delight by adding ½ cup crumbled feta cheese, ¼ cup chopped sun-dried tomatoes, and 2 tablespoons of chopped Kalamata olives. Finish with a sprinkle of dried oregano before baking. This variation brings bright, tangy notes that complement the spinach beautifully.

Protein-Packed Option: For a heartier version, add 1 cup of diced ham or crumbled cooked bacon to the egg mixture. The saltiness of the meat enhances the mild flavor of the spinach and adds satisfying texture. This makes your quiche particularly suitable as a complete meal rather than just a side dish.

Dairy-Free Adaptation: Create a dairy-free spinach quiche without crust by substituting the milk and cream with unsweetened almond milk or coconut milk, and using your favorite dairy-free cheese alternative. Add a tablespoon of nutritional yeast to the egg mixture to enhance the “cheesy” flavor. The result is surprisingly creamy and satisfying for those avoiding dairy.

Storage and Serving

Your Easy Crustless Spinach Quiche will keep beautifully in the refrigerator for up to 4 days when stored in an airtight container. For longer storage, freeze individual slices wrapped tightly in plastic wrap and placed in a freezer bag for up to 2 months. Reheat refrigerated quiche in a 325°F (165°C) oven for 15 minutes or until warmed through; microwave individual slices for 1-2 minutes.

For an elegant brunch presentation, serve wedges of quiche alongside a simple arugula salad dressed with lemon vinaigrette—the peppery greens and bright dressing cut through the richness perfectly. For a light dinner, pair with roasted cherry tomatoes that burst with sweetness and a glass of crisp white wine.

My favorite morning option is to enjoy a slice at room temperature with a dollop of crème fraîche and a few turns of freshly cracked black pepper. The contrast of cool, tangy cream against the warm spice elevates this simple crustless spinach quiche to something truly special.

FAQs

Can I use fresh spinach instead of frozen?
Yes! Substitute about 1 pound (450g) of fresh spinach for the 10 oz of frozen. Sauté it first until wilted, then cool and squeeze out excess moisture before adding to your quiche mixture.

Why is my quiche watery?
The most common culprit is inadequately drained spinach. Make sure to squeeze out as much moisture as possible. Also, avoid overbaking, which can cause the proteins to separate from the liquids.

Can I make this ahead of time?
Absolutely! You can prepare the entire quiche up to two days ahead and refrigerate it. Alternatively, prepare the egg mixture and store it separately from the sautéed ingredients, combining and baking when ready.

Is this quiche keto-friendly?
Yes, this Easy Crustless Spinach Quiche is perfect for keto diets as it’s naturally low in carbohydrates. The eggs, cheese, and cream provide healthy fats while the spinach adds nutrients without significant carbs.

Can I add other vegetables?
Certainly! Just ensure any added vegetables are cooked and well-drained before adding. Great options include sautéed mushrooms, roasted red peppers, or steamed broccoli. Keep the total volume of add-ins similar to the original recipe for proper cooking.
