Hello Midwest_Dan! Baking chicken tenders can definitely be tricky because they are so thin and lean, which makes them overcook and dry out in a matter of minutes if you are not careful. Fortunately, there are a few simple grocery store tricks that will keep them juicy every single time.
First, try using mayonnaise or full-fat Greek yogurt as a binder before applying your seasoning or breadcrumbs. Mayo might sound unusual, but it is just an emulsion of oil and egg. Coating your chicken tenders in a thin layer of mayo traps the natural moisture inside and creates a tender barrier as it bakes. Alternatively, soaking them in pickle juice or buttermilk for 15 to 30 minutes before baking acts as a fast brine that tenderizes the meat and helps it retain water.
Second, pay close attention to your baking temperature and time. Chicken tenders should be cooked hot and fast rather than low and slow. Preheat your oven to 400 degrees Fahrenheit or 425 degrees Fahrenheit and bake them for only 12 to 15 minutes, depending on their thickness. The single best tool you can use is an instant-read meat thermometer. Pull the chicken out of the oven as soon as the thickest part reaches 165 degrees Fahrenheit.
Finally, give your tenders about 5 minutes to rest on the pan or a cutting board before serving. Resting allows the juices inside the meat to redistribute instead of running out onto your plate. I hope these simple adjustments make a noticeable difference for your weeknight meals!
