How long and what temperature do you cook a 3 pound boneless turkey breast in a conventional oven?

For a 3-pound boneless turkey breast, roast it in a preheated conventional oven at 350°F (175°C) for approximately 1.5 to 2 hours. The internal temperature should reach 165°F (74°C) for safe consumption. It's a good idea to use a meat thermometer to ensure it’s cooked thoroughly. Let it rest for about 10-15 minutes before slicing to retain moisture.
