Use ripe but still fairly firm avocados so the halves hold their shape and minimize egg leakage. If using large eggs, you may want to discard a small amount of egg white before filling the avocado wells so they do not overflow too much. These avocado egg cups are best enjoyed fresh for the creamiest texture but can be reheated gently at low power in the microwave. Pair with bacon, sausage, or a simple green salad for a complete keto breakfast or brunch.
