What Makes This Quiche Healthy?

A few simple swaps are what give this quiche its healthy status: skipping the crust saves on carbs and saturated fat, while loading up on veggies adds fiber and nutrients. You can use low-fat cheese or dairy-free milk, and even add in lean protein like turkey sausage or tofu for extra staying power.

Ingredients for the Healthy Crustless Quiche

6 large eggs
1/2 cup milk (dairy or plant-based)
1/2 cup shredded cheddar cheese (or your choice)
1/2 cup diced bell peppers
1/2 cup chopped spinach
1/4 cup chopped onion
1/4 tsp garlic powder
1/4 tsp salt
1/8 tsp black pepper
Olive oil spray (for the baking dish)

How To Make the Healthy Crustless Quiche

Step 1: Preheat and Prep

Preheat your oven to 375°F (190°C). Lightly grease a 9-inch pie dish with olive oil spray to prevent sticking.

Step 2: Whisk the Eggs

In a large bowl, whisk together the eggs and milk until smooth. This is the base of your quiche, so make sure it’s well blended.

Step 3: Add the Flavor

Stir in the cheese, bell peppers, spinach, onion, garlic powder, salt, and black pepper. Mix until everything is evenly distributed.

Step 4: Pour and Bake

Pour the mixture into the prepared pie dish and gently tap it on the counter to even out the surface. Bake for 35–40 minutes, or until the center is set and the edges are golden.

Step 5: Cool and Serve

Allow the quiche to cool for at least 5 minutes before slicing. This helps it set and makes for cleaner slices.

How to Serve and Store Healthy Crustless Quiche

Serve your crustless quiche warm with a side of fresh fruit or a green salad for a complete meal. It also makes a fantastic addition to brunch spreads alongside muffins or breakfast potatoes.

Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. To reheat, simply microwave individual slices for about 30 seconds to 1 minute or warm in the oven at 300°F until heated through. This quiche also freezes well—wrap slices in foil and store in a freezer bag for up to 2 months.

Frequently Asked Questions

Can I use egg whites instead of whole eggs?

Yes, you can substitute some or all of the whole eggs with egg whites. Use about 2 egg whites per whole egg for best results.

What other veggies work well?

Zucchini, mushrooms, tomatoes, or kale are all great choices. Be sure to sauté water-heavy vegetables first to avoid excess moisture.

Can I make this dairy-free?

Absolutely! Use your favorite plant-based milk and swap the cheese for a dairy-free alternative or nutritional yeast.

Is this keto-friendly?

With a few tweaks—like using heavy cream instead of milk and keeping cheese full-fat—this quiche can be made keto-friendly.

Can I add meat?

Definitely. Cooked turkey sausage, bacon bits, or diced ham can all be folded in before baking.
