Recipe Description

Say goodbye to heavy, calorie-laden brunch dishes. This Cottage Cheese & Spinach Crustless Quiche is a revelation—incredibly light and fluffy in texture, yet satisfyingly rich in flavor and protein. By skipping the traditional pastry crust, we highlight the creamy, savory filling starring cottage cheese, eggs, and vibrant spinach. It’s a versatile meal-prep champion, equally glorious for a leisurely weekend breakfast, a quick weekday lunch, or a simple dinner paired with a crisp salad. Gluten-free and keto-friendly, this quiche proves that healthy eating can be utterly delicious.

Ingredients

• 1 tablespoon olive oil or butter

• 1 medium yellow onion, finely diced

• 2 cloves garlic, minced

• 5 ounces (about 5 cups) fresh baby spinach, roughly chopped

• 6 large eggs

• 1 ½ cups (12 oz) full-fat or low-fat cottage cheese (small curd preferred)

• 1 cup (4 oz) shredded cheese (a blend of cheddar and mozzarella works well), divided

• ¼ cup grated Parmesan cheese

• ¼ cup milk (any fat percentage)

• 1 tablespoon all-purpose flour (or gluten-free 1:1 substitute)

• ½ teaspoon baking powder (for extra lift)

• ½ teaspoon kosher salt

• ¼ teaspoon black pepper

• ¼ teaspoon ground nutmeg (optional, but highly recommended)

• Cooking spray or extra butter for greasing

Instructions

1. Prep and Sauté:
Preheat your oven to 375°F (190°C). Lightly grease a 9-inch pie dish or a deep quiche pan with cooking spray or butter.
Heat the olive oil in a large skillet over medium heat. Add the diced onion and cook for 4-5 minutes until softened and translucent. Add the minced garlic and cook for another minute until fragrant.
Add the chopped spinach in batches, stirring until each batch wilts down before adding more. This should take 3-4 minutes total. Remove the skillet from the heat and let the mixture cool slightly.

2. Blend the Base:
In a blender or food processor, combine the eggs, cottage cheese, ½ cup of the shredded cheese, Parmesan cheese, milk, flour, baking powder, salt, pepper, and nutmeg. Blend on high for 20-30 seconds until the mixture is completely smooth and uniform. (This step is key for the signature fluffy texture!).

3. Combine and Pour:
In a large bowl, pour the blended egg mixture over the slightly cooled spinach and onion. Stir gently to combine. Pour the entire mixture into your prepared pie dish. Tap the dish lightly on the counter to release any air bubbles. Sprinkle the remaining ½ cup of shredded cheese evenly over the top.

4. Bake to Perfection:
Carefully place the quiche in the preheated oven. Bake for 40-50 minutes. The quiche is done when the center is just set (a slight jiggle is okay) and the top is a beautiful, puffed golden brown. A knife or toothpick inserted near the center should come out clean.

5. Rest and Serve:
This is a crucial step! Remove the quiche from the oven and let it cool and settle in the pan on a wire rack for at least 15 minutes. It will deflate slightly as it cools, making it easier to slice cleanly.
Serve warm, at room temperature, or even chilled. Garnish with fresh herbs like chives or parsley if desired.

Storage & Reheating

Lasting Quality: Store leftover quiche, covered tightly in the refrigerator, for up to 4 days.
Reheating: Reheat individual slices in the microwave for 60-90 seconds, or in a 350°F (175°C) oven or toaster oven for 10-12 minutes until warmed through. You can also freeze the fully baked and cooled quiche (whole or in slices) for up to 2 months. Thaw overnight in the refrigerator before reheating.

Chef’s Notes & Variations

• Cottage Cheese Texture: For the silkiest, most uniform quiche, blending is essential. Don’t skip it! If you prefer a bit of curd texture, blend everything except the cottage cheese, then stir it in at the end.

• Add-Ins: Make it your own! Add ½ cup of diced cooked ham, crumbled cooked bacon, sautéed mushrooms, or sun-dried tomatoes when you combine the spinach and egg mixture.

• Cheese Swap: Feel free to experiment with different cheeses. Gruyère, feta, or goat cheese would be delicious additions.

• Make it Dairy-Free: Use a dairy-free cottage cheese alternative, nutritional yeast instead of Parmesan, and your favorite plant-based shredded cheese and milk.
