Sheet Pan Ranch Chicken and Vegetables

We love the mighty sheet pan here at LCK! This hands-off cooking method makes getting a delicious meal on the table simple and the clean up is a breeze. We’ve tested a range of recipes for different meal occasions and varying cooking time, but mostly we just love that utilizing the sheet pan allows for unattended cooking, giving us EXTRA time in our busy lives.

Sheet Pan Ranch Chicken and Vegetables

Tips for sheet pan cooking:

  • Read the recipe all the way through (of course) and plan to use a timer! Most recipes require different cooking times, so make sure to use a timer so you can truly walk away from the oven and not have to worry about when your adding anything in to the oven.
  • Do the prep ahead of time: Cut vegetables, make sauce or mix spices the night before or that morning if you are looking to speed up the process when it comes time for the actual cooking.
  • Use parchment paper to make clean up a breeze.
  • Use the correct size sheet pan. When we say sheet pan we are referring to the rimmed half sheet pan which is 18″ by 13″. The size of the sheet pan matters because you do not want to overcrowd the pan when cooking, so if you are using a smaller sheet pan you may need to use 2 to achieve the same result.

  1. Such a yummy dinner!! Only things we had to add were 2 lemons and double all the spices in the ranch. Used Primal kitchen avocado mayo and found that the mayo flavor was just too overpowering without the lemon. What kind of mayo did you use when you made this?

    Will definitely be adding this to the list of quick and easy recipes to make!! LOVE your food

    1. Ooops!!!! Maybe we were too high then.
      (Kidding- we time these things, but of course, it can take some longer than others).

  2. Can’t wait to try making that homemade ranch mix!! So many uses for it…:)
