Ingredients

  • 8 large eggs

  • 1 1/2 cups shredded cheddar cheese, divided

  • 1/2 cup milk

  • 1 bunch green onions, thinly sliced (about 1 cup), divided

  • 1/2 teaspoon salt

  • 1/4 teaspoon black pepper

  • 1 tablespoon butter, softened (for greasing)

Directions

  • Preheat oven to 325 degrees F. Generously grease a 9-inch oven-safe dish with softened butter to prevent sticking.
  • In a large bowl, whisk eggs, milk, salt, pepper, half the green onions, and 1 cup cheese until smooth and frothy, about 1 minute. The milk is the key: it creates steam pockets for fluffiness and prevents rubbery proteins from overcooking.
  • Pour mixture into prepared dish. Sprinkle remaining 1/2 cup cheese evenly on top.
  • Bake for 20 to 25 minutes, until edges are set but center jiggles slightly (internal temp 160 degrees F). Avoid high heat, which toughens eggs, broil 1 to 2 minutes for golden top if needed.
  • Let rest 5 minutes to set fully. Garnish with remaining green onions. Slice and serve warm for perfect pull-apart cheese.

Notes

    The milk creates steam pockets for fluffiness and prevents rubbery eggs. Bake at low heat and check internal temp reaches 160°F. Let rest 5 minutes before slicing.
