Ingredients You’ll Need

• 16 ounces egg whites
• 1 cup cooked crumbled turkey sausage (or bacon/diced ham)
• 1 cup bell peppers (chopped)
• 1-2 cups spinach (chopped)
• ½ cup cherry tomatoes (diced)
• ½ cup onion (chopped)
• ¾ teaspoon Kosher salt
• ¼ teaspoon ground black pepper

You’ll also want a little olive oil for sautéing the vegetables and nonstick cooking spray for the muffin tin.

How to Make Egg White Muffins

Step 1: Prep the pan and tomatoes.
Preheat the oven to 350°F. Spray a nonstick or silicone muffin tin generously with cooking spray so the muffins release easily. Set the diced tomatoes on a paper towel to soak up extra moisture, which keeps the muffins from turning watery.

Step 2: Sauté the vegetables.
Warm a little olive oil in a nonstick pan over medium-high heat. Add the bell pepper and onion and cook for 2 to 3 minutes until they begin to soften.

Step 3: Add the meat, spinach, and tomatoes.
Stir in the cooked sausage, spinach, and tomatoes, and cook for about 2 more minutes so everything is heated through and the spinach wilts.

Step 4: Fill the muffin cups.
Spoon about a heaping tablespoon of the filling into each muffin cup.

Step 5: Add the egg whites.
Whisk the egg whites with the salt and pepper in a medium bowl, then pour the mixture over the filling in each cup. Leave about ¼ inch of space at the top so they have room to puff.

Step 6: Bake.
Bake for 23 to 30 minutes, until the muffins have puffed up and a toothpick inserted in the center comes out clean.

Step 7: Release and serve.
Run a knife around the edge of each muffin to loosen it, then pop it out. Serve hot, with extra tomatoes, salsa, or hot sauce if you like a little kick.

• Cook time: 25 minutes
• Total time: 35 minutes
• Servings: 12 muffins

Tips for the Best Results

• Grease the pan well. Egg whites stick easily, so be generous with the spray, or use a silicone tin.
• Blot the tomatoes. Excess moisture can make the muffins soggy.
• Don’t fill the cups to the top. Leaving a little room lets them puff without overflowing.
• Sauté the vegetables first. Cooking off some of their moisture keeps the texture light and fluffy.
• Try different fillings. Bacon, diced ham, mushrooms, or a sprinkle of cheese all work well.

Storage & Reheating

Store the muffins in an airtight container in the refrigerator and eat them within 5 days. To freeze, cool them completely, wrap them individually or place them in a freezer bag, and reheat in the microwave straight from the freezer or after thawing overnight in the fridge.

Serving Suggestions

• On their own as a grab-and-go breakfast
• Tucked into a whole grain English muffin for a quick breakfast sandwich
• With fresh fruit for a balanced morning plate
• Topped with salsa, hot sauce, or sliced avocado for extra flavor

Final Thoughts

Egg White Muffins make healthy eating easier because breakfast is already made. They’re fluffy, savory, and full of protein, and they reheat well, so a single batch can carry you through a busy week.
