Preheat oven to 375 degrees F and place a rack in a large rimmed baking sheet. You can also use a roasting pan.
In a small bowl, add melted butter, garlic, rosemary, smoked paprika, salt and pepper. Stir to combine.
Place turkey breast on a large plate and pat dry with paper towels. Using hands or brush, rub turkey breast with seasoned butter all around. Make sure to rub the meat part, in the crevices and under the skin whenever possible.
Place turkey breast side up on previously prepared baking sheet and pour broth on a side.
Bake uncovered for 20 minutes per pound or until internal temperature in the deepest part of meat reaches 150 - 155 degrees F when checked with thermometer. Actual time will depend on the size of your turkey breast.
Remove from the oven, cover loosely with foil and let rest for 15 minutes. This is when turkey breast will reach 165 degrees F.
Slice against the grain using a sharp knife and serve.

Roast breast with skin on to keep it moist. It acts as a barrier and insulator for dry poultry. You can always remove it after.
Broth at the bottom of the pan is to keep oven moist while baking meat.
