When it comes to this mashed potato-topped casserole, here in the United States we turn convention on its head—or maybe sideways—and break more than a few rules.

Geographically speaking, this slightly spicy, very cheesy, chicken, bean, corn, and mashed potato pie takes a drastic turn southwest from its origins. But hold the eye roll if you’re comparing it to the traditional version made with lamb and potatoes from the British Isles.

Tex-Mex Shepherd’s Pie is a stellar comfort dish, worthy as an addition to your weeknight rotation. It’s filling, satisfying, and family-friendly. It’s so good. Let’s not quibble with the name.

Time-Saving Tips

The whole dish doesn’t take much prep time if you:

  • Don’t peel the potatoes: This is a rustic dish, and it’s covered with a blanket of cheese, so shazam! Into the pan they go with the skins.
  • Make the filling while you boil the potatoes. Cooking the vegetables in this dish takes under 15 minutes, about the same time as the potatoes.
  • Use leftover chicken or about half a rotisserie chicken.
  • Buy grated cheese.

Tips to Make Ahead and Freeze Shepherd's Pie

First, assemble the casserole (through step 5).

  • Refrigerate the pie covered with plastic wrap for up to three days before baking. Allow it to come to room temperature and bake for 25 to 30 minutes. You may need an extra 10 minutes if the pie is not hot enough in the center. If it browns before the center is hot, cover loosely with foil.
  • Or freeze, covered with a double layer of plastic wrap, for up to two months. Remove from the freezer and defrost in the fridge overnight. Bake as above.

Prep Time 25 mins
Cook Time 30 mins
Total Time 55 mins
Servings 6 to 8 servings

Ingredients

  • 2 1/2 pounds (5 to 6 medium) Yukon Gold potatoes
  • 1 tablespoon salt, divided
  • 4 tablespoons unsalted butter, cut into slices
  • 1/2 cup milk, or more as needed
  • 1 1/2 cups grated sharp cheddar cheese
  • 1/8 teaspoon pepper
  • 2 tablespoons olive oil
  • 1 medium onion, finely chopped
  • 1 large garlic clove, finely chopped
  • 1 teaspoon dried oregano
  • 1/2 teaspoon ground cumin
  • 1 (15-ounce) can black beans, rinsed and drained
  • 1 cup frozen corn
  • 2 cups shredded, cooked chicken
  • 2 cups of your favorite salsa

Method

  1. Preheat the oven:

    to 425oF. Have on hand a 9- x 13-inch or 2-quart, shallow baking dish.

  2. Cook the potatoes:

    Wash and cut the potatoes into 1-inch chunks (peeling optional). Place them in a large pot. Fill the pot with cold water until there is about an inch of water above the potatoes.

    Add 2 teaspoons salt and taste; the water should taste as briny as the sea. If it doesn’t, add a few more pinches of salt.

    Bring to a boil over high heat. Reduce the heat to a simmer and cook the potatoes, uncovered, for 15 to 20 minutes, or until tender when pierced with the tip of a paring knife.

    Drain in a colander and return to the potatoes to the pot. Set the pot over low heat and stir the potato chunks for 1 to 2 minutes to dry them.

  3. Mash and season the potatoes:

    Add the butter to the pot of hot, drained potatoes (still over low heat) and mash well with a potato masher until the butter melts. There may be a few ‘rustic’ lumps. Push the potatoes to one side of the pot to make a space for the milk. Add the milk and heat it until hot (this only takes a few seconds.)

    Use a sturdy whisk to stir in the milk, whisking until the potatoes are fluffy and adding more milk, 1 tablespoon at a time, if the potatoes seem dry. Stir in 1/2 cup of the cheese, 1/2 teaspoon salt and 1/8 teaspoon pepper. Taste, and add more salt, if you like.

  4. Meanwhile, make the filling:

    In a large skillet over medium heat, heat the oil. Add the onions and garlic and cook for 5 minutes, or until softened. If the onions are cooking to fast reduce the heat to medium-low.

    Add the oregano and cumin, and cook for 30 seconds. Add the beans, corn, chicken, and salsa to the skillet. Stir in 1/2 teaspoon salt. Taste and add more salt, if you like.

  6. Bake the casserole:

    Bake for 25 to 30 minutes, or until the filling bubbles and the cheese is golden. Leftovers will keep in the fridge for up to 3 days.
