If you like cheddar cheese, fermented peppers, or jalapeño poppers, then you are going to love these jalapeño cheddar burgers! These homemade Jalapeno Cheddar Burgers are made with grass-fed lean ground beef, sharp cheddar cheese, fermented jalapeños, and my special seasoning blend. The cheddar and fermented jalapeños are added into the grass-fed beef burger patties, for a flavorful, juicy, slightly spicy burger you’ll want to make for every summer barbecue.
