Eddie Jackson greets the last three chefs for the big finale and tells them that they'll be preparing the ultimate summer party. In their first challenge, the chefs have 30 minutes to create three kabobs with summer party themes and one chef will get skewered early by judges Damaris Phillips and Jamika Pessoa, who are joined by barbecue experts Susie Bulloch and Cameron Treu. In the second and final heat, the two remaining chefs have 60 minutes to create an elevated dinner and dessert for the ultimate summer dinner party, but the only heat source they can use is the grill. In the end, one chef wins the Ultimate Summer Cook-Off and $25,000!
