Combine the cornstarch with the stock and sherry before adding it to the hot pan to keep the gravy smooth.
1 (1-pound) pork tenderloin, trimmed
1/2 teaspoon salt
1/2 teaspoon freshly ground black pepper
3 garlic cloves, minced
1 teaspoon olive oil
1 (8-ounce) package sliced baby bella mushrooms
1/3 cup chopped shallots (about 4)
2 teaspoons cornstarch
1 cup beef stock (such as Swanson)
1 tablespoon dry sherry
How to Make It
Cut pork diagonally into thin slices. Sprinkle pork with salt and pepper; rub with garlic. Heat a large nonstick skillet over medium-high heat. Coat pan with cooking spray; add oil. Add pork; cook 1 to 2 minutes on each side or until done. Transfer pork to a platter; keep warm.
Recoat skillet with cooking spray. Add mushrooms and shallots; cook, stirring often, 5 minutes.
While mushroom mixture cooks, place cornstarch in a small bowl. Gradually add stock and sherry, stirring with a whisk until smooth. Stir stock mixture into mushroom mixture, scraping to loosen browned bits. Bring to a boil; cook, stirring constantly with a whisk, 1 minute or until thickened. Return pork and accumulated juices to pan; cook 1 to 2 minutes or until thoroughly heated.
This was wonderful and so easy and quick! I slightly pounded the pork slices flat and browned them in a very small amount of olive oil in my cast iron skillet to get a good, brown crust. Finely sliced red onions were a good substitute for the shallots as I was out of them. I also added more beef broth, requiring more corn starch, so we would have gravy for mashed potatoes. These changes increased the total calorie count, but very satisfying with a lean meat. I served with steamed broccoli and squeezed with some lemon juice. Can't wait to make this good meal again.
