Soft, custardy egg muffins packed with spinach and feta cheese, designed for easy meal prep and a healthy, high-protein breakfast on the go.
Use room temperature eggs for even mixing. If using frozen spinach, thaw and squeeze out all excess water to prevent soggy muffins. Do not overbake; centers should still jiggle slightly as they will firm up while cooling. For best texture, use block feta crumbled by hand rather than pre-crumbled.
