Shepherd's pie is one of those dishes, that is unapologetically comforting, and no fuss. Topped with the best, creamy mashed potatoes, this easy weeknight shepherd's pie is perfection.
Brown the Chicken and Mushrooms: While the potatoes are cooking in the InstantPot, in a skillet, brown the shallot and garlic in 1 tablespoon of oil. Add the ground chicken, and break apart.
Make the Sauce: Add the tomato paste, and cook through for a minute. Sprinkle with flour, and cook for another minute. Add the Worcestershire sauce, chicken broth, and spices.
