Preheat the oven to 375 degrees F.
Line a baking sheet with aluminum foil and set aside.
Clean the mushrooms and place in a small bowl. If you're using whole mushrooms you can bake the mushrooms like that or slice them up.
Season the mushrooms with oil knorr, Italian season, salt and pepper. Mix and set aside.
Peel the carrot, slice and season with oil, Italian season, salt and pepper. Mix to combine.
Spread the carrots on one side and the mushrooms on the other side of the lined baking sheet.
Bake in the preheated oven for 25 minutes or until the carrots and mushrooms are cooked. If you have some liquid in the pan while baking drain it out (you use it in another cooking) and continue to roast.
Remove when done, serve and enjoy!
