Roasted Turkey Breast Tenderloin

Who’s tired of dried out, overcooked turkey? I know I am. Roasting a turkey breast tenderloin is a sure-fire way to get juicy turkey slices every time. This turkey comes out so tender and juicy that you won’t even need any gravy. Since packages of turkey breast tenderloin are widely available at most grocery stores, this recipe is an awesome dinner option that you can enjoy all year long. Read on to learn how to make this super easy recipe for Roasted Turkey Breast Tenderloin.


You’ll first need a bed of vegetables for the turkey breast tenderloin to lay on. This will ensure the tenderloin is raised up enough for even cooking all around. Depending on which vegetables you choose, they also add some amazing flavor to the turkey. I always use onions and carrots. Potatoes are a great alternative as well. 


Other than the obvious star of this recipe (the turkey tenderloin), we can’t forget about the equally important supporting character: the marinade. Marinades are what make or break most recipes in my opinion. And I’m happy to report that this marinade made the cut with flying colors! You can’t really go wrong when your marinade includes mustard and a lot of garlic. 😉

This marinade is a mouthwatering mixture of olive oil, TWO types of mustard, garlic, thyme, onion powder, salt and pepper. It covers the turkey breast tenderloin generously on all sides and develops a deliciously perfect color, synonymous with roasted food.

The great thing about this recipe is that it’s very low maintenance. Preparation is a breeze and then you can simply put it in the oven to roast for 45 minutes. Afterward, I’d suggest letting the turkey breast tenderloin rest about 10 minutes before slicing into it. Letting the tenderloin rest before slicing allows for the juices to really soak into the turkey breast instead of leaking out immediately. It adds to the juiciness, tenderness and flavor of the turkey as a whole. It also makes for easier slicing.
