Preheat the oven to 400 F. Line a baking sheet with parchment paper.

Cut the chicken into 1 to 1-1/2 inch pieces. Add to a bowl with the spicy ranch and mix well, until all the chicken is fully coated with the ranch.

Add the Cornflakes to a large Ziploc bag and, using a rolling pin or your hands, crush until small pieces and fine crumbs remain. Add to a separate large, shallow bowl.

Using a fork, dip the coated chicken into the Cornflakes, making sure each piece is fully covered.

Place chicken on the lined baking sheet in an even layer, making sure the nuggets don’t overlap. Drizzle olive oil on top and bake in the preheated oven for 10 minutes.

Flip the chicken over, drizzle again with olive oil, and bake for another 5 minutes or or until an internal temperature of 165 F is reached.
