These are a fun, protein-packed appetizer that feels like a treat, not a compromise. The hasselback technique creates crispy edges and pockets for a tangy-sweet mustard glaze to caramelize. They are perfect for parties, game day, or as a quick, impressive snack.
Use chopsticks as guards to prevent slicing all the way through. Patting the sausage dry helps the glaze stick. For a spicier version, use andouille sausage or add cayenne to the glaze. Reheat leftovers in an air fryer or toaster oven to maintain crispness.
