Ingredients Equipment Method Notes

Ingredients
  

  • 8 large eggs fresh and at room temperature
  • 1 cup milk whole milk preferred
  • 1.5 cups shredded sharp cheddar cheese or substitute with Monterey Jack or Parmesan
  • 1 cup diced bell peppers sautéed until tender
  • 1 cup chopped spinach fresh or frozen, sautéed to reduce moisture
  • 4 strips bacon cooked until crispy, optional
  • 2 tablespoons fresh chopped parsley or chives for brightness
  • to taste salt and pepper for seasoning

Equipment

  • 9x13 inch baking dish
  • Mixing bowls
  • Whisk or fork
  • Sauté pan
  • Spatula or spoon
  • Oven thermometer (optional)

Method
 

  1. Preheat your oven to 175°C (350°F). Lightly grease your baking dish with butter or non-stick spray. In a large bowl, whisk together the eggs, milk, salt, and pepper until smooth and slightly frothy.
  2. In a sauté pan, cook diced bell peppers and chopped spinach until the vegetables are tender and fragrant, about 3-4 minutes. Let them cool slightly.
  3. Pour the sautéed vegetables evenly over the bottom of the prepared baking dish, creating a colorful base.
  4. Sprinkle the shredded cheddar cheese evenly over the vegetables, distributing it to cover the layer completely.
  5. Crumble the cooked bacon over the cheese, if using, for a savory crunch.
  6. Slowly pour the egg mixture over the layered ingredients, allowing it to seep into all the nooks and crannies. Gently shake the dish if needed to ensure even coverage.
  7. Sprinkle chopped parsley on top for a fresh, herbal note. Place the dish in the oven and bake for 35-40 minutes, until the edges are golden and the center is just set with a slight jiggle.
  8. Remove from the oven and let the casserole rest for about 5-10 minutes—this helps it set up and makes slicing easier. The top should be golden and bubbly.
  9. Slice into squares, serve warm, and enjoy the fluffy, cheesy goodness paired with the savory vegetables and crispy bacon.

Notes

You can customize this casserole with your favorite vegetables or meats. Make it vegetarian by skipping bacon or add mushrooms for umami. It’s perfect for prepping the night before—just assemble, chill, and bake in the morning.
