Endemol Shine North America and Blue Apron have joined forces to develop a Mystery Box Challenge Fox’s culinary competition series “MasterChef Junior.”

During the episode, each contestant will open his or her Mystery Box to reveal a Blue Apron Family Plan box with a choice of two proteins and an assortment of vegetables. The contestants will then have 45 minutes to curate a dinner recipe using 10-12 ingredients and items from the “MasterChef Junior” pantry.

The winner will have their recipe featured in an upcoming Blue Apron Family Plan menu. Additionally, all eight contestants will receive one year of Blue Apron meals.

The “MasterChef Junior” episode featuring Blue Apron will air tonight, April 20, on Fox.
