Preheat your oven to 400°F and line a sheet pan with parchment paper.

Chop the carrots crosswise into 2-inch sections, then slice each section in half lengthwise.

Mix together olive oil, salt, garlic, onion powder, red pepper flakes, and rosemary in a large bowl. Toss the carrot pieces until they are well coated.

Sprinkle 1 ½ cups of parmesan cheese over the prepared parchment paper.

Arrange each carrot onto the parmesan-coated pan, cut side down.

Top the carrots with the remaining parmesan cheese.

Bake for 30-35 minutes, or until the carrots are easily pierced with a knife.

Serve warm and enjoy.
