• 2 cups fresh spinach, washed and roughly chopped
• 1 small onion, diced
• 2 cloves garlic, minced

Eggs & Cheese

• 6 large eggs

👩‍🍳 Step-by-Step Instructions

🔹 Step 1: Preheat Oven & Prepare Dish

1. Preheat oven to 180°C (350°F).
2. Lightly grease a 9-inch pie dish or any oven-safe baking dish with butter or olive oil.
   • Tip: You can also line it with parchment paper for easier serving.

🔹 Step 2: Prepare Vegetables

1. Clean mushrooms with a damp cloth, then slice evenly (~¼-inch thick).
2. Roughly chop spinach; if using frozen, thaw and squeeze out excess water.
3. Dice onion finely and mince garlic.

🔹 Step 3: Sauté Vegetables

1. Heat 1 tbsp olive oil or butter in a skillet over medium heat.
2. Add diced onion → cook 2–3 minutes until softened and translucent.
3. Add mushrooms → cook 5–6 minutes until they release moisture and turn golden brown.
4. Add garlic → cook 30 seconds until fragrant.
5. Add spinach → cook 1–2 minutes until wilted.
6. Season lightly with salt, pepper, and dried thyme or oregano.
   • Tip: Don’t over-salt yet if using feta, as it’s naturally salty.
7. Remove vegetables from heat and let cool slightly.

🔹 Step 4: Prepare the Egg Mixture

1. Crack 6 eggs into a medium bowl.
2. Add ½ cup milk or cream, crumbled feta, parmesan (optional), pinch of nutmeg, salt, and pepper.
3. Whisk thoroughly until smooth and slightly frothy.
   • Tip: Whisking incorporates air for a fluffier quiche.

🔹 Step 5: Combine & Pour

1. Spread sautéed vegetables evenly in the prepared baking dish.
2. Pour the egg and cheese mixture over the vegetables.
3. Use a spatula or spoon to gently distribute vegetables so every bite has even fillings.

🔹 Step 6: Bake

1. Place dish in preheated oven.
2. Bake 35–40 minutes until the quiche is set and slightly golden on top.
   • Check doneness: quiche should be firm to the touch, with no jiggly center.
   • Optional: Broil 1–2 minutes at the end for a lightly browned top.

🔹 Step 7: Rest & Serve

1. Let quiche rest 5–10 minutes before slicing.
   • Resting allows the quiche to firm up and makes slicing easier.
2. Garnish with chopped fresh parsley or chives.
3. Serve warm, at room temperature, or even cold.

🌿 Flavor Notes

• Earthy mushrooms provide a meaty texture.
• Spinach adds freshness and color.
• Feta gives tangy creaminess; parmesan adds umami depth.
• Nutmeg enhances savory richness subtly without overpowering.
• Aromatic herbs tie all flavors together.

💡 Tips for Success

• Use fresh eggs for better structure.
• Don’t overcook—the center should be just set for a creamy texture.
• Crustless quiche is naturally low-carb but can be paired with toast or salad.
• Make ahead: quiche tastes even better the next day; store in airtight container in the fridge for 2–3 days.

🔄 Variations

• Add cherry tomatoes or roasted red peppers for sweetness.
• Include cooked bacon, ham, or sausage for extra protein.
• Make mini crustless quiches in a muffin tin for meal prep.
• Swap feta for goat cheese or cheddar for a different flavor profile.
