Brown the ground sausage in a skillet before adding to the egg mixture to ensure even cooking and prevent raw pockets throughout the muffins.

Allow the filled muffin tin to sit at room temperature for 5 minutes before baking so eggs cook evenly and prevent the edges from setting before the centers are done.

Line your muffin tin with silicone cups or grease generously to prevent sticking and ensure your muffins release cleanly without breaking apart.

Gently whisk eggs just until combined—overmixing incorporates excess air that causes tunneling and creates a rubbery, uneven texture in the finished muffins.

Let muffins cool completely on a wire rack before storing to prevent condensation, which keeps them from becoming soggy and maintains their firm, muffin-like structure.
