To keep these egg bites as fluffy as possible, avoid overbaking and remove them from the oven as soon as they are just set in the center. Different muffin pans conduct heat differently, so start checking a few minutes early the first time you make them. You can swap the veggie mix-ins for other low-carb options like finely chopped zucchini or green onions, but keep the total volume similar to avoid changing the texture and carb count. For an even easier release, you can use silicone muffin cups placed on a baking sheet instead of a metal muffin pan.
