Cook chicken breast just until done. You can boil, bake or cook in the instant pot. Make sure you don't overcook or your nuggets will be dry.
In a food processor or blender, pulse together cooked chicken breast, eggs, salt, garlic powder and onion powder.
To make shapes, press the chicken mixture into cookie cutters. Then press into your bread crumbs. If you don't want to make shapes, roll a small ball of chicken mixture into a ball, and slightly press until flat and shaped like a chicken nugget. Then press into breadcrumbs.
Place nuggets onto a cookie sheet. Drizzle with melted butter to make them crispier.
Bake at 400 degrees for about 10 minutes. Flip halfway through to get both sides crispy.
Serve with your favorite dip like honey mustard, ketchup, spicy mustard, BBQ sauce, or ranch. Enjoy!
