First, make the yogurt marinade. Add the 0-fat greek yogurt, milk, lemon juice, garlic, oregano, salt, and pepper to a large airtight container. Whisk these ingredients together.
Add the chicken tenders to the airtight container and cover them with the yogurt marinade. Then, place the airtight container in the refrigerator. Let the chicken marinate for at least 4 hours or overnight.
Once marinated, remove the chicken from the airtight container. Leave a thin coat of the yogurt mixture on the chicken, but get the extra marinade off so it doesn’t make the cornflakes soggy.
Add the cornflakes to a large Ziploc bag, seal the bag, and use a rolling pin to crush the cornflakes. Then, add the crushed cornflakes to a large shallow bowl.
Add the Italian seasoning, garlic powder, onion powder, oregano, dried parsley, smoked paprika, salt, and pepper to the shallow bowl with the crushed cornflakes. Thoroughly mix these ingredients.
Dredge the marinated chicken in the cornflake mixture. Make sure both sides of all of the chicken tenders are thoroughly coated with the cornflake mixture.
Lightly spray a sheet pan with olive oil and place all of the chicken tenders on the sheet pan. Then, lightly spray the chicken tenders with olive oil before placing them in the oven.
Bake the chicken in the oven at 375℉ for 11-12 minutes on one side. Then, carefully flip each piece of chicken and bake the other side for another 11-12 minutes or until the chicken is fully cooked, which is when it reaches an internal temperature of 165℉.
Once the chicken is fully cooked, let it slightly cool, and enjoy!
