Compared to the average 60-minute quiche (with crust preparation), this crustless version gets you from cravings to caving in delight more quickly—making it ideal for on-the-go mornings or make-ahead meals.
Step-by-Step Instructions
Step 1: Preheat & Prepare the Dish
Preheat your oven to 375°F (190°C). Lightly grease a 9-inch pie dish or baking dish with olive oil or cooking spray to prevent sticking and add flavor depth.
📝 Tip: Preheating ensures even cooking and a golden top layer.
Step 2: Sauté Aromatics
In a medium pan, sauté onions and garlic in a splash of olive oil over medium heat for 3–4 minutes until soft and fragrant.
🔄 Swap option: Want to skip a step? Use onion and garlic powder directly in the egg mixture.
Step 3: Whisk the Egg Mixture
In a large bowl, whisk together eggs, milk, salt, and pepper until light and frothy. This helps the quiche puff up beautifully while baking.
🧠 Did You Know? Aerating the eggs by whisking well adds natural fluffiness without any added cream.
Step 4: Add the Fillings
Fold in chopped spinach, sautéed onions/garlic, and half the shredded cheese into the egg mixture—mix well.
🌿 Variation: For richer flavor and added texture, stir in sun-dried tomatoes or sautéed mushrooms at this stage.
Step 5: Bake It!
Pour the mixture into your greased dish. Top with remaining cheese. Bake for 30-35 minutes, or until the center is firm and edges are slightly golden.
⏲️ Check-Point: A toothpick or knife inserted should come out clean when it’s perfectly cooked.
Step 6: Cool & Serve
Cool for at least 5–10 minutes before slicing. This allows the quiche to set for clean slices and better flavor development.
🥳 Bonus Tip: Serve warm, at room temp, or even chilled—the flavor just keeps improving!

Common Mistakes to Avoid
Avoiding these pitfalls ensures your crustless quiche turns out flawless every time:
🥴 Mistake 1: Underseasoning
Eggs need seasoning. Don’t skip the salt, pepper, and additions like garlic to boost depth.
💧 Mistake 2: Using wet spinach
If you’re using frozen spinach, always squeeze out excess moisture. Wet greens will water down the quiche.
🔥 Mistake 3: Uneven mixing
Ensure your fillings are evenly distributed so that every bite gets a good mix of textures and flavors.
🌡️ Mistake 4: Overbaking
This can cause rubbery texture—always check at the 30-minute mark for doneness.
