To use it in chicken heat your oven to 400°F.
Pour breadcrumbs, paprika, garlic powder, celery salt, onion powder, Italian seasoning, garlic salt, sea salt, black pepper, and oil into a large resealable plastic bag or mixing bowl with a lid.
Add a piece of chicken to the bag. Seal it and shake chicken until it is well-coated with your homemade bake mix. Place the chicken in a single layer on a baking sheet and repeat this shaking process with the rest of the chicken.
Bake the chicken for 20 minutes.
Remove them from the oven, flip the chicken over, and bake for another 10 minutes or until the internal temperature reaches 165°F.
