  • Muffin tin


  • 12 large eggs
  • 1/2 tsp kosher salt
  • 1/4 tsp cracked black pepper
  • 2-3 scallions, thinly sliced (about 1/3 cup)
  • 3/4 cup grated cheddar cheese
  • 1 can of King Oscar Brisling Sardines in Extra Virgin Olive Oil, drained and roughly chopped


  • Preheat oven to 350º F.
  • Lightly grease a muffin tin.
  • Crack all of the eggs into a large bowl and whisk until eggs are cohesive. Add the salt, pepper, half of the scallions and 1/4 cup of the grated cheddar cheese. Give the mixture a good stir and carefully pour it into each of the muffin cups on the muffin tin, about 3/4 of the way up.
  • Top each of the servings with the rest of the scallions, cheese, and evenly distribute the chopped sardines over each one.
  • Bake in the oven for 20 minutes, or until the eggs are cooked through.
  • Let the egg muffins cool for about 10 minutes before trying to pop them out of the muffin tin. Use a knife along the edges of each egg muffin to help release it from the muffin tin if needed.
  • Serve the muffins on their own or on toasted English muffins with a slice of cheese and other additions of your liking.


Feel free to add other veggies into the mix, like chopped tomatoes, spinach, etc.
