Easy Crustless Healthy Quiche Recipe

This crustless healthy quiche recipe is one of my favorite ways to get a serious protein boost at breakfast without spending time cooking every morning.

Made with lean turkey sausage, sautéed peppers and onions, spinach, low-fat cheddar, whole eggs, and egg whites, it’s fluffy, filling, and perfect for a grab-and-go meal prep breakfast.

Unlike traditional quiche, there’s no heavy cream and no crust, which keeps carbs lower while letting the protein shine.

If you prefer a classic crust, you’ll love my high-protein spinach and onion quiche too.

Why Make a Crustless Healthy Quiche Recipe?

A crustless healthy quiche recipe simplifies everything.

There’s no blind baking, no worrying about soggy bottoms, and no added crust calories. Instead, the focus stays on the protein-rich filling — eggs, egg whites, turkey sausage, and vegetables.

It’s a great option if you want:

• a lower-carb breakfast
• a faster prep process
• something lighter but still filling
• an easy meal prep breakfast that reheats well

If you love quiche but don’t need the pastry, this version keeps things simple and satisfying.

Why This Healthy Quiche is Higher in Protein

This recipe uses a mix of whole eggs and egg whites to increase protein without making the texture heavy. Lean turkey sausage adds additional protein while keeping fat moderate.

Unlike traditional quiche made with heavy cream, this version uses 2% milk to keep things lighter while still creamy.

The result is a high protein breakfast that supports muscle maintenance, satiety, and balanced blood sugar.

Ingredients You’ll Need For Healthy Quiche Recipe

• 3 whole eggs
• 1 cup liquid egg whites
• ⅓ cup 2% milk
• ⅓ cup diced onion
• ⅓ cup diced red bell pepper
• ⅓ cup cooked turkey sausage crumbles
• 1 cup baby spinach
• ¼ cup shredded cheese (mozzarella + cheddar blend)
• salt & pepper to taste

The combination of whole eggs and egg whites keeps the texture rich while boosting protein and lowering overall calories

The total cost for this crustless turkey sausage quiche is approximately $8–10, depending on the brands used. That works out to about $1.00–$1.25 per slice, making it an affordable high protein breakfast option for meal prep.

How to Make Crustless Turkey Sausage Quiche

Sauté the vegetables

In a skillet over medium heat, cook bell pepper and onion until softened, about 4 – 5 minutes. Add spinach and cook until wilted.

Heat the sausage

In the same pan, add the pre-cooked sausage crumbles and cook until slightly brown.

Mix the eggs

In a large bowl, whisk together:

• whole eggs
• egg whites
• milk
• cheese
• salt & pepper

Add the veggie mixture

To the egg and milk mixture, add the veggie and sausage mixture and stir to combine.

Assemble

Spray a pie dish or casserole dish with non-stick spray. Pour egg and sausage mixture into the pan.

✨ NOTE: You may have a little extra filling depending on the size of your dish. Avoid overfilling so the eggs cook evenly.

Bake

Bake at 350°F for 35–45 minutes, or until the center is set. Let rest for 10–15 minutes before slicing.

Makes about 8 servings.

How to Tell When Crustless Quiche Is Done

Because there’s no crust, texture matters. The quiche is ready when:

• the center is set but slightly soft
• a knife inserted comes out clean
• the edges are lightly golden

If it jiggles too much in the center, bake 3–5 minutes longer.

Let it rest before slicing so it firms up properly.
