Common Mistakes to Avoid

1. Adding wet spinach directly to the egg mixture
   Fresh spinach releases water as it cooks, which can make the quiche watery. Wilt it first and squeeze or drain away excess moisture.
2. Overbaking the quiche
   Baking too long can make the eggs rubbery and dry. Remove it when the center is just set and has only a slight jiggle.
3. Using an overcrowded filling
   Too many vegetables can release excess moisture and interfere with setting. Keep the filling close to the specified quantities for a reliable texture.
4. Cutting it immediately after baking
   The center needs a few minutes to firm up. Rest the quiche for about 10 minutes before slicing.

Required Equipment

• 9-inch pie dish or quiche dish — Provides the right depth and surface area for even baking.
• Non-stick skillet — Makes wilting the spinach and sautéing aromatics quick and easy.
• Mixing bowl — Gives enough room to combine the eggs, cottage cheese, and seasonings evenly.
• Whisk — Helps distribute the cottage cheese and eggs for a consistent custard.
• Rubber spatula — Makes transferring the spinach and egg mixture into the baking dish easier.
• Measuring cups and spoons — Keep ingredient quantities consistent for predictable texture and nutrition.

Storage Instructions

Refrigerator: Allow the quiche to cool before storing. Place individual slices in airtight containers or wrap the whole quiche tightly. Refrigerate for up to 4 days.

Freezer: For longer storage, wrap individual slices in freezer-safe wrap and place them in a freezer-safe airtight container or bag. Freeze for up to 2 months for best quality.

Reheating: Thaw frozen slices overnight in the refrigerator when possible. Reheat refrigerated slices in a 350°F (175°C) oven for 8–12 minutes, or microwave for about 45–90 seconds, depending on your microwave. Avoid overheating because it can make the eggs tough.

Because the recipe is naturally protein-focused, storing it properly preserves its protein content; texture is the main quality factor that changes during refrigeration or freezing.

📝 Ingredients

• 1 cup low-fat 2% cottage cheese — Provides creaminess and protein.
• 4 large eggs
• 3 cups fresh spinach, roughly chopped
• ½ cup shredded part-skim mozzarella cheese
• ¼ cup finely diced yellow onion
• 1 garlic clove, minced
• 1 teaspoon olive oil
• ¼ teaspoon salt
• ¼ teaspoon black pepper
• ¼ teaspoon dried Italian seasoning

Ingredient note: If your cottage cheese or mozzarella is particularly salty, reduce the added salt to taste.

Directions

1. Preheat the oven to 375°F (190°C).
   Lightly grease a 9-inch pie dish with a small amount of olive oil or non-stick spray.
2. Wilt the spinach and aromatics.
   Heat a non-stick skillet over medium heat and add 1 teaspoon olive oil. Add the onion and cook for 2–3 minutes, until slightly softened. Add garlic and cook for 30 seconds.
3. Add the spinach.
   Add the chopped spinach and cook over medium heat for 1–2 minutes, stirring frequently, until wilted. Remove from the heat and drain or gently squeeze out excess moisture. This is an important high-protein cooking tip because excess liquid can weaken the quiche’s structure.
4. Prepare the egg mixture.
   In a large bowl, whisk the eggs, cottage cheese, salt, black pepper, and Italian seasoning until well combined. A few small cottage cheese curds are perfectly fine.
5. Combine the filling.
   Stir the cooled spinach mixture and half of the mozzarella into the egg mixture. Mix gently rather than aggressively, which helps maintain a tender texture.
6. Fill the baking dish.
   Pour the mixture into the prepared dish and spread it evenly. Sprinkle the remaining mozzarella over the top.
7. Bake for 30–35 minutes.
   Bake at 375°F (190°C) until the edges are set and lightly golden and the center is firm but still has a very slight jiggle. A knife inserted near the center should come out mostly clean.
8. Rest before serving.
   Remove from the oven and let the quiche rest for 10 minutes. This allows the protein-rich egg and cottage cheese mixture to finish setting and makes cleaner slices.
9. Serve.
   Slice into 6 portions and serve warm. For extra flavor, add fresh herbs, cracked black pepper, or a small pinch of red pepper flakes.
