Equipment

  • 1 skillet
  • 1 casserole dish

Ingredients 

  • 5 russet potatoes diced small
  • 10 eggs
  • ¾ cup milk
  • 1 onion chopped
  • 2 cloves garlic minced
  • 2 carrots finely diced (optional)
  • 1 cup cooked chicken chopped (optional)

  • 2 tablespoons butter
  • 1 teaspoon salt or to taste
  • ½ teaspoon black pepper
  • ½ teaspoon paprika optional

  • Pinch oregano optional
  • 1/2 cup green onions (I used the greens from wild garlic instead)

Instructions

  • Preheat your oven to 375°F and lightly grease a baking dish.
  • Melt butter in a large skillet over medium heat. Add diced potatoes and cook for 10–15 minutes, stirring occasionally, until softened and lightly golden.
  • Add onion, garlic, carrots, and onions to the skillet. Cook for 5–7 minutes, until softened and fragrant.
  • Transfer the potato mixture to the prepared baking dish. Add cooked chicken (if using) and sprinkle cheese evenly over the top. Gently mix.
  • In a bowl, whisk together eggs, milk, salt, pepper, and any optional seasonings.
  • Pour the egg mixture evenly over the casserole.
  • Bake for 35–45 minutes, until the center is set and the top is lightly golden.
  • Remove from the oven, sprinkle some optional green onions on top after baking, and let the casserole rest for 10 minutes before slicing and serving.
