Be sure to zest your orange before you cut and juice it. If I have enough zest, you can save a little to sprinkle on after cooking but that's optional.
Add the orange zest, orange juice, olive oil, honey, and salt to a bowl and wisk until the honey has incorporated smoothly.
Toss the carrots in the sauce mixture to coat them.
Add the carrots and all of the sauce to a 9x13 pan or a sheet pan and cover with aluminum foil.
Bake for 15 minutes while covered then remove the cover and bake for another 15 minutes or until the carrots are tender. I sometimes will broil them for about 5 minutes at the end to get a little more golden color.
Optional: sprinkle with the reserved orange zest and a bit of fresh parsley and serve warm.
