Add bacon into a 10 inch ovenproof skillet and heat over medium heat until browned. Remove bacon from pan and drain on paper towel.
Wipe out the skillet and add shredded carrots and broccoli pieces, cooking for around 3 minutes, stirring frequently.
Add evaporated milk, garlic powder, onion powder, oregano, salt, and pepper and mix well.
Stir in shredded cheese, cooked pasta, cooked chicken, cooked bacon, and reserved pasta water. Heat over medium heat, stirring frequently, until cheese is combined and melted and mixture is hot. Serve immediately.
Notes
If you drain the pasta water instead of reserving it, substitute chicken broth or extra evaporated milk. Use only the broccoli florets, discarding the tougher stem, for the best texture.
