These are absolutely irresistible! My husband loves having these in the morning. He couldn't believe it was made with just a few ingredients.

Allow the quiche cups to cool slightly before serving.

For a vegetarian version, replace the sausage or bacon with sautéed mushrooms or spinach. You can also experiment with different cheeses, such as Swiss or feta, to add a unique flavor profile. If you prefer a spicier kick, consider adding a dash of hot sauce or a sprinkle of red pepper flakes to the egg mixture. These quiche cups can be made ahead of time and stored in the refrigerator for up to three days, making them a convenient option for busy mornings.
