About This Recipe
Each bite is silky, savory, and full of herbaceous flavor from fresh spinach and a touch of nutmeg. The eggs puff gently in the oven, creating a soft, custard-like texture that’s balanced by just enough low-fat cheese to keep it satisfying but still light.
This is one of those “set-it-and-forget-it” recipes that works beautifully for weekend brunch or weekday meal prep. Serve it warm or cold, slice it for grab-and-go breakfasts, or pair it with a simple salad for a light dinner.
Why This Recipe Belongs in Your Diet
Using egg whites and fat-free milk keeps the fat low without sacrificing protein or flavor. The spinach adds fiber and iron, while skipping the crust eliminates about 8–10 grams of fat per serving. It’s a smart, balanced way to enjoy something cozy and comforting while sticking to your healthy eating goals.
What You’ll Need (Ingredients)
This recipe keeps things simple with clean ingredients and a few flavor-boosting extras.
- Fresh Baby Spinach, 5 cups: Wilts down beautifully and brings fiber, vitamins, and a pop of green.
- Egg Whites, 6 large: High-protein, low-fat, and help the quiche stay light and fluffy.
- Whole Eggs, 2 large: A little yolk adds richness and color without overdoing the fat.
- Fat-Free Milk, 1 cup: Keeps the custard creamy while cutting calories and fat.
- Yellow Onion, 1 small, finely chopped: Adds savory depth and natural sweetness.
- Garlic, 2 cloves, minced: Boosts flavor without any added fat.

How to Make Low Fat Crustless Spinach Quiche
- Preheat oven to 375°F and lightly spray a 9-inch pie dish with nonstick cooking spray.

- Whisk eggs and milk in a large bowl. Add salt, pepper, and nutmeg.
- Stir in the cooked spinach mixture and cheese until well combined.
- Pour the mixture into the prepared pie dish and smooth the top.
- Bake for 35–40 minutes, or until the center is just set and a knife inserted comes out clean.
- Let it rest for 10 minutes before slicing and serving.

Recipe Tips and Variations
- Add chopped mushrooms or bell peppers for extra veggies.
- Swap the cheddar for low-fat feta or mozzarella for a different twist.
- Use a silicone pie pan to prevent sticking without needing extra oil.
- For extra flavor, stir in fresh herbs like dill or parsley.
