This is a simple recipe, but when it's finished it is more than the sum of its parts. The combination of mustard, lemon, thyme, and garlic is delicious and transforms plain old turkey into something worthy of serving to company.

Serve this flavorful turkey dish with rice pilaf, a green salad tossed with sliced avocados and cucumbers, and some toasted garlic bread. For dessert, make a luscious chocolate cake or serve an ice cream pie.

Tip

When both zesting and juicing a lemon for a recipe, it is easier to zest first and then cut the lemon in half to squeeze out the juices. Also, don't forget to wash off the lemon before zesting.

Do I Have to Let the Meat Rest?

It is important not to skip the step where the tenderloin rests. When you put the turkey in the oven, the heat causes the cells to contract, squeezing the liquid out and away from the heat, toward the center of the piece of meat. If you slice the turkey as soon as it comes out of the oven, all that liquid will end up on the cutting board. Waiting a few minutes allows the meat to cool slightly and the muscle fibers to relax; the juices will redistribute throughout the meat, resulting in a more tender and juicy piece of meat.

Recipe Variation

Instead of baking the turkey tenderloins, you can grill them. Remove the turkey from the marinade, allowing the excess to drip off, and place on a hot grill. Cook for 8 to 10 minutes a side, depending on thickness, until they reach 160 F. Let rest before slicing.
