Ingredients

Egg Mixture

  • 6 large eggs
  • 1/4 cup heavy cream
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper

Vegetables

  • 1 cup broccoli florets, chopped
  • 1/2 cup red bell pepper, diced
  • 1/2 cup mushrooms, sliced

Other

  • 1 cup shredded cheddar cheese
  • 1 tablespoon olive oil (for greasing and sautéing vegetables)

Instructions

  1. Preheat Your Equipment: Preheat your oven to 375°F (190°C) and lightly grease your baking dish with olive oil to prevent sticking.
  2. Sauté Vegetables: In a pan, heat olive oil and lightly sauté broccoli, red bell pepper, and mushrooms until just tender to enhance their flavors before mixing with eggs.
  3. Combine Ingredients: In a mixing bowl, whisk together the six eggs, heavy cream, salt, and black pepper until well combined. Stir in the shredded cheddar cheese and the sautéed vegetables ensuring an even distribution.
  4. Prepare Your Cooking Vessel: Ensure the baking dish is lightly oiled or lined with parchment paper to facilitate easy removal after baking.
  5. Assemble the Dish: Pour the egg mixture evenly into the prepared baking dish, spreading the vegetables and cheese evenly throughout.
  6. Cook to Perfection: Bake in the preheated oven for 25-30 minutes until the eggs are set and the top is lightly golden brown.
  7. Finishing Touches: Allow the casserole to cool for 5 minutes to let it set properly, helping it hold its shape when sliced.
  8. Serve and Enjoy: Cut into squares and serve warm. Optional sides like avocado slices or a fresh salad complement this dish well.

Notes

  • Use fresh vegetables for the best texture and flavor.
  • Do not overcook the eggs to keep them fluffy and moist.
  • Cover leftovers loosely with foil or plastic wrap when storing to maintain freshness.
  • Feel free to customize with different cheeses such as mozzarella or gouda, or swap vegetables according to preference.
