Preheat oven to 400 °F (204 °C) and line a baking pan with two layers of foil and place chicken into the pan.
In a measuring cup, whisk together onion soup mix, catalina dressing, and apricot preserves.
1 package of dry onion soup mix, 1 cup catalina dressing, 1 cup apricot preserves
Pour the mixture all over the chicken.
1 1/2 pounds boneless skinless chicken thighs
Bake uncovered for 40-50 minutes, or when the internal temperature of the chicken reaches 165 °F (74 °C)
While baking, you'll want to baste it often with either a brush or a baster. Just so the chicken gets re-coated with the delicious sauce.
If you want, 5 minutes or so before the chicken is done, you can pop it under the broiler to get the sauce to caramelize a bit on the chicken but this is totally optional.
