How to Bake Crustless Spinach Quiche

Step 1: Prepare Oven and Baking Dish

Set the oven to 350°F. Grease an 8-inch square baking dish with butter or non-stick cooking spray to prevent sticking.

Step 2: Cook Crispy Bacon

Sizzle diced bacon in a large skillet over medium heat until it turns golden and crisp. Transfer bacon to paper towels to drain excess grease.

Keep about 1 teaspoon of bacon drippings in the pan.

Step 3: Sauté Aromatic Onions

Using the bacon grease, cook chopped onions in the same skillet.

Stir frequently over medium heat until onions become soft and translucent.

Step 4: Wilt Fresh Spinach

Add fresh spinach leaves to the skillet.

Continuously stir and cook until spinach completely wilts and loses its moisture.

Step 5: Layer Dish with Ingredients

Spread the spinach and onion mixture evenly in the prepared baking dish.

Sprinkle cooked bacon pieces over the spinach, then top with shredded cheese.

Step 6: Blend Liquid Mixture

In a mixing bowl, whisk together:
  • Low-fat milk
  • All-purpose flour

Ensure the mixture becomes completely smooth.

Step 7: Create Egg Base

Continue whisking and add:
  • Whole eggs
  • Egg white
  • Ground black pepper
  • Salt
  • Onion powder
  • Dried oregano

Mix until all ingredients are well combined.

Step 8: Assemble Quiche

Pour the egg mixture evenly over the layered spinach, bacon, and cheese.

Optional: Dust the top with sweet paprika for extra flavor and color.

Step 9: Bake to Perfection

Slide the baking dish into the preheated oven.

Bake for 30-40 minutes until the quiche sets firmly and turns golden brown.

Tips to Nail Crustless Spinach Quiche

  • Drain bacon thoroughly to prevent excess grease and maintain a crispy texture in the quiche.
  • Select fresh, crisp spinach leaves for the best flavor and nutrient-packed result.
  • Try different cheese varieties like feta or goat cheese for unique taste profiles.
  • Opt for low-fat milk to reduce calories without compromising the creamy consistency.
  • Store leftovers in an airtight container and reheat gently to preserve the quiche's delicate texture.

Variations to Customize Crustless Spinach Quiche

  • Vegetarian Spinach Quiche: Replace bacon with roasted bell peppers or mushrooms for a meat-free version. Use plant-based cheese to maintain the creamy texture.
  • Gluten-Free Option: Substitute all-purpose flour with almond flour or cornstarch. Ensure all ingredients are certified gluten-free for those with dietary restrictions.
  • Low-Carb Modification: Swap milk with heavy cream and use fewer onions. Add extra cheese and spinach to boost protein and keep the dish satisfying for keto dieters.
  • Mediterranean Style: Incorporate feta cheese instead of regular shredded cheese. Add sundried tomatoes and fresh oregano to enhance the Mediterranean flavor profile.

Pairing Ideas with Crustless Spinach Quiche

  • Sauvignon Blanc or Pinot Grigio complement the quiche's rich, creamy texture and cut through the bacon's saltiness.
  • Create a light mixed green salad with lemon vinaigrette to balance the quiche's hearty flavors and add refreshing crunch.
  • Serve warm sourdough or crusty artisan bread to soak up the quiche's delicious egg custard and provide a satisfying textural contrast.
  • Add a side of fresh berries or a light fruit compote to introduce a sweet, tangy element that brightens the savory quiche profile.

Storage Advice for Crustless Spinach Quiche

  • Refrigerator Storage: Place cooled quiche in an airtight container or wrap tightly with plastic wrap. Keep refrigerated for up to 3-4 days to maintain freshness and prevent bacterial growth.
  • Freezer Storage: Slice quiche into individual portions, wrap each piece in freezer-safe plastic wrap, then place in a freezer bag. Freeze for up to 2 months without losing quality or taste.
  • Microwave Reheating: Warm individual slices on a microwave-safe plate for 45-60 seconds. Cover with a damp paper towel to prevent drying and maintain moisture.
  • Oven Reheating: Restore crispy texture by warming slices in a preheated 350°F oven for 10-15 minutes. Cover with aluminum foil to prevent excessive browning and keep the quiche moist.
