Dijon Herb Crusted Pork Tenderloin

Pork tenderloin is one of the most forgiving cuts in the butcher case. It is lean, it cooks quickly, and it takes a herb rub without fuss. This version is built on a simple paste of Dijon mustard, garlic and dried herbs. The mustard does more than add flavor. It helps the rub cling to the meat, so you get a savory crust rather than a loose dusting that falls off in the pan.

Give the rub its full two hours in the fridge if you can. Dried rosemary and thyme are woody and a little sharp when they first hit the meat, and that edge softens as they sit. If you forget and only manage thirty minutes, the dish still tastes good, but the herbs will sit on top rather than sink in.

A few things I have learned from cooking this more than once. Brown the tenderloins hard before they go in the oven. You want a deep golden color on every side, which takes a few minutes per face in a hot skillet, and it is where most of the flavor comes from. Space them out in the baking dish so the heat reaches them evenly and the browned bits do not steam. And use a thermometer. Pork cooked to 160 to 170 F stays juicy, and guessing by color is how people end up with dry slices. Once it comes out, let it rest for ten to fifteen minutes. Cut too early and the juice runs across the board instead of staying in the meat.

Leftovers are a real gift here. Slice what you do not eat and wrap it tightly in the fridge for up to three or four days. It is excellent cold on a salad, or tucked into a sandwich with a smear of extra mustard. Cold slices also hold their shape better than warm ones, so they are easy to portion.

For a plate that comes together without extra work, I like a bowl of Roasted Potato and Cauliflower Salad alongside the pork. The potatoes and cauliflower pick up the same herbs and make the meal feel complete. If you want something lighter and brighter on the side, Kale Salad with Quinoa, Cranberries and Feta gives a nice contrast of sweet, salty and fresh.

Dijon itself is a good thing to keep around. It came out of the city of Dijon in France, and its sharpness comes from brown or black mustard seeds mixed with verjuice or wine rather than vinegar alone. That is why it adds bite without making the pork taste sour. A jar in the door of the fridge will last for months, and you will find yourself reaching for it on everything from salad dressings to roasted vegetables.
