Ingredients

The following ingredients have 4 Servings
  • 2 pounds ground beef ((or ground lamb))
  • 1 large sweet onion, (peeled and chopped)
  • 1 1/2 cups chopped carrots
  • 5 cloves garlic, (minced)
  • 1 cup frozen corn
  • 1 cup frozen peas
  • 1 1/2 cups beef broth
  • 1/4 cup tomato paste
  • 3 tablespoons Worcestershire sauce
  • 2 tablespoons Dijon mustard
  • 1 tablespoon cornstarch
  • 2 teaspoons dried thyme
  • 5 cups mashed potatoes ((store-bought or homemade))
  • 1 cup shredded cheddar cheese
  • salt and pepper

Instruction

  • Preheat the oven to 400 degrees F.
  • Place a deep 13-14 inch cast iron skillet over medium heat. Add the ground beef, and sprinkle generously with salt and pepper. Break the ground beef into small pieces, with a wooden spoon, as it browns.
  • Once the ground beef is fully cooked, move it to the sides of the skillet. Add the onions, carrots, and garlic. Sauté for 5-8 minutes to soften the onions and carrots. (The carrots should be partially cooked before baking.)
  • Stir the mixture together. Then add in the frozen corn and pea, broth, tomato paste, Worcestershire sauce, mustard, cornstarch, and thyme. Mix well. Taste, then salt and pepper as needed.
  • Turn off the heat. Spread the mixture evenly over the bottom of the skillet.
  • Mix the shredded cheese into the mashed potatoes. (If using store-bought mashed potatoes, you may need to drain off the extra liquid or press the top with paper towels, before mixing in the cheese.)
  • Scoop the mashed potatoes over the meat filling and spread it to the sides of the skillet, making sure there are no gaps. Immediately place the cottage pie in the oven. Bake for 20-25 minutes, until golden on top.
