Pour this 1 sauce over pork tenderloin in a roasting pan for a cozy dinner that’s surprisingly addictive

For picky eaters who shy away from mustard, you can cut the whole grain mustard down to 1 tablespoon and add an extra tablespoon of maple syrup for a slightly sweeter sauce. If your family loves herbs, try adding a pinch of thyme or sage along with the rosemary.

To make it a one-pan meal, scatter baby potatoes and carrot chunks around the pork before pouring the sauce over everything; just make sure the vegetables are cut small enough to cook through in about the same time as the pork. For a slightly smoky twist, add 1/2 teaspoon smoked paprika to the sauce.

If you prefer a thicker, more glaze-like sauce, remove the cooked pork to rest and pour the pan juices into a small saucepan; simmer for a few minutes on the stove until slightly reduced, then spoon over the sliced pork. Leftovers make great sandwiches—pile sliced pork on a bun with a little extra mustard and some pickles for an easy next-day lunch.
