Wild boar boneless loin can be prepared much like domesticated pork loins. Wild boar is much leaner than domesticated pork, however, so a little extra care must be taken not to overcook it.
Here's my favorite preparation method:
Lightly season the meat. It can be as simple as salt and pepper. You may choose to apply some of your favorite rub or some fresh herbs. Just go easy - the more spices you add, the less you will actually taste the meat.
Heat a skillet with oil over medium-high heat. Sear the meat for about 2 minutes per side.
Transfer the meat to 400° F oven to finish cooking. You can use a baking sheet or, if your skillet is oven-proof, just put the skillet into the oven.
Roast until the loin reaches an internal temperature of 150° F, about 10 minutes.
Let it rest for about 10 minutes then serve. While you're waiting you can make a quick pan sauce, like a mustard cream sauce, to serve on the side. Or just enjoy it without a sauce!
