  • Total Time: 55 minutes
  • Yield: 9 servings

Ingredients

Vegetables

  • 1 small onion, diced
  • 1 red bell pepper, diced
  • ¼ cup fresh chives, finely diced, plus more for garnish

Protein

  • 1 lb ground turkey
  • 12 eggs
  • 2 cups (16 oz) cottage cheese
  • 1 cup shredded cheddar cheese

Seasonings & Other

  • Oil, for cooking
  • 1 teaspoon sea salt, divided
  • 1 ½ teaspoons garlic powder
  • ¼ teaspoon ground black pepper

Instructions

  1. Prep: Gather all ingredients and preheat your oven to 375°F (190°C). Grease a 9 x 13-inch casserole dish with oil to prevent sticking during baking.
  2. Sauté Vegetables: Heat oil in a large skillet over medium heat. Add diced onion and red bell pepper. Cook, stirring occasionally, for about 5-7 minutes or until the vegetables are softened. Remove them from the skillet and transfer to a large mixing bowl.
  3. Cook Turkey: Add a bit more oil to the same skillet. Add ground turkey along with ½ teaspoon of the sea salt. Stir and crumble the meat as it cooks over medium heat for about 6-8 minutes until lightly browned and cooked through. Transfer the cooked turkey to the bowl with the sautéed vegetables and let cool slightly.
  4. Prepare Egg Mixture: In a blender, add the remaining ½ teaspoon sea salt, eggs, cottage cheese, garlic powder, black pepper, and finely diced chives. Blend until the mixture is smooth and evenly combined. Alternatively, use an immersion blender in a bowl for mixing.
  5. Combine: Pour the blended egg mixture into the bowl with the cooled turkey and vegetables. Stir thoroughly to incorporate all ingredients evenly.
  6. Assemble: Pour the combined mixture into the greased casserole dish and spread it out evenly. Sprinkle shredded cheddar cheese over the top and optionally garnish with extra chopped chives for color.
  7. Bake: Cover the casserole dish with foil and bake in the preheated oven for 20 minutes. Then remove the foil and continue baking for an additional 15-20 minutes until the eggs are fully set and the top has turned golden brown.
  8. Rest and Serve: Let the casserole rest for 10 minutes after baking to allow it to firm up before serving. Slice into portions and enjoy your high-protein breakfast!
