Once you've chopped up your vegetables and peeled your garlic, spread it evenly in 2 sheet pans. The drizzle some olive oil on top.
Arrange your chicken after seasoning it with salt and pepper (thighs skin up), onto the sheet pans evenly. Pour in a splash (or 3 tbsp) of chicken broth into the pans.
Place the sheet pans into the oven for around 40 minutes (more if you want crisper skin).
Notes
I had some extra chicken breast in the fridge so I threw it in, hence why this meal prep needed 2 instead of 1 pan.
