Roasted Turkey Tenderloin Recipe

This roasted turkey tenderloin recipe started out as a slow cooker recipe. But one day I decided to try it in the oven. Both methods turn out delicious results!

If seasoned properly, this roasted turkey tenderloin is delicious any time of year. When I make any holiday meal, I’m just as likely to cook this as I am a whole turkey because it’s so much easier, and it tastes wonderful! 

I’ve always loved a turkey dinner with all of the traditional sides. It brings back so many wonderful memories!

We enjoy having leftover turkey, and these tenderloins typically give us just enough for a couple of extra meals. I chop it up into smaller pieces and add it to salads or make leftover turkey soup.

There’s no point in waiting for any specific season to cook a turkey tenderloin since it’s so easy. You can enjoy it in a refreshing summer recipe.

Or make a yummy fall dish with dressing, sweet potatoes, green bean casserole, and the rest of your favorite holiday foods.

In other words, it’s perfect as a picnic food or part of a Thanksgiving meal. Yes, you can make this your Thanksgiving turkey without the hassle of wrestling a huge bird that takes hours and hours to cook.

Crockpot Turkey Tenderloin Recipe

If you want to cook your turkey tenderloin in your Crock Pot, then by all means, do it. I like it both ways—in the oven or in the slow cooker. In fact, I’ve even used my air fryer. 

This time I made it in the oven because I wanted more of a roast turkey flavor. 

The key to preparing any meat is to cook it long enough but to never overcook it. With turkey, you don’t want it raw. But you don’t want it dried out, which is what will happen if you cook it too long.

When I cook Crockpot turkey breast, I marinate it just like I would for the oven method. Then put it in the slow cooker on high for about an hour and then turn it down to low heat to finish cooking.

I have a 6 quart Crock Pot, which is plenty big enough for the entire turkey tenderloin.

After about 5 hours, check the internal temperature by inserting a meat thermometer into the thickest portion of the meat.

If it’s at 165˚ F or above, it’s done. Even when you’re slow cooking a turkey, you need to remove it from the heat before it’s overcooked.

Remove the meat from the slow cooker and let it rest on a platter for about 10 to 15 minutes before slicing. You can use the juices in the Crockpot to make gravy or to spoon over the meat.

If you want to cook a regular whole turkey breast, try this Crock Pot turkey recipe that is just as delicious. It’s perfect for the family that likes all white meat.

Optional Ingredients

There are quite a few other ingredients that you can add to the marinade. If there’s a spice or seasoning you like, give it a try. Chances are, it will be good.

Here are some other ingredients you might want to try:

Marinate the Meat

Before you begin cooking the turkey breast tenderloin, marinate it for at least an hour or up to 24 hours. I often start the marinating process either the night before or early in the morning on the day I’m going to cook it.

whisking ingredients for marinade

Combine all of the ingredients except the turkey tenderloin in a medium bowl.

Stir until everything is well mixed. This is the marinade.

Place turkey tenderloin in a gallon size plastic bag. Now pour the marinade over the turkey.

Seal the bag and massage the marinade into the meat.

Put the bag in a bowl in case it leaks. Stick the turkey in the refrigerator and let it sit there for at least a few hours so it can soak up the marinade.

How to Roast a Turkey Tenderloin

Preheat your oven to 350˚ F. Spray a baking pan with nonstick cooking spray.

Remove the turkey from the bag and place it in the baking dish.

Save 1/4 cup of the marinade in a small bowl to baste the turkey a few minutes before it’s done. You can discard the remaining marinade or make a flavorful gravy with it. 

If you like gravy, you can also make this yummy but super easy turkey gravy that is gluten-free. And no one I’ve served it to can tell the difference! And it’s such an easy recipe!

Some turkeys come with a gravy packet, but most of the time that’s not the case with the tenderloins. You can add it to your homemade gravy, offer it as an alternative, or toss it.

basting the turkey tenderloin

Bake the turkey uncovered in a shallow baking pan for 40 minutes. Baste the turkey with the extra marinade.

Return it to the oven for an additional 5 to 10 minutes. The cooking time can vary according to the size of the tenderloin and the oven’s temperature accuracy.

meat thermometer in the turkey tenderloin

Remove it from the oven. Now you need to check the internal temperature to make sure it’s done.

Insert the meat thermometer into the thickest part of the meat. It’s done when the temperature reaches 165˚ F, according to USDA guidelines.

If the turkey is not done yet, return it to the oven for an additional 5 minutes. Be careful not to overcook it. Overcooked, dry turkey isn’t as good as perfectly cooked turkey.

Once the tenderloin reaches the proper internal temperature, remove it from the oven and put it on a platter. Allow it to rest for about 15 minutes before slicing.

Serve this yummy roasted turkey tenderloin with your favorite sides.
