    Cooking Spray
  • In a large bowl, whisk together the eggs and milk until fully combined.
    10 Lrg Eggs, 1 Cup 2% Milk
  • Rinse the cocktail tomatoes and cut them in half. Using a small teaspoon, scoop out the seeds and soft interior. Finely dice the remaining tomato shells.
    2 Cocktail Tomatoes
  • Remove the blossom ends from the mini sweet peppers. Slice each pepper in half lengthwise and remove the seeds and any white membrane. Cut into thin strips, then finely dice.
    4 Mini Sweet Peppers
  • Cut the red onion in half and remove the outer skin. Place one half cut-side down and slice into thin half-moon slices. Gather the slices and cut across them in the opposite direction to create finely diced onion.
    ½ Cup Red Onion
  • Rinse the spinach leaves and pat dry with paper towels. Remove the stems and finely chop the leaves.
    10 Baby Spinach Leaves
  • Fill each muffin cup approximately three-quarters full with the egg mixture.
  • Working one ingredient at a time, divide the tomatoes evenly among the muffin cups, adding about 1 teaspoon to each cup. Repeat with the onion, sweet peppers, and spinach.
  • Sprinkle the tops lightly with black pepper.
    Black Pepper
  • Bake for approximately 12 minutes, or until the centers are fully set.
  • To test for doneness, lightly touch the center of an egg bite. If any uncooked egg transfers to your finger, continue baking for another minute or two.
  • Allow the egg bites to cool slightly before removing them from the muffin pan.
  • Repeat with remaining egg mixture and vegetables.

Notes

Notes

  • Egg bites naturally puff while baking and settle slightly as they cool.
  • Grease the muffin pan well, even if it is nonstick.
  • Pat the spinach dry after washing to prevent excess moisture.
  • Store in an airtight container in the refrigerator for up to 4 days.
  • Freeze cooled egg bites in a single layer before transferring them to a freezer bag for longer storage.
  • Makes 18 egg bites.
