  • 2 medium sweet potatoes, peeled and diced
  • 1 cup fresh spinach, chopped
  • 1 red bell pepper, diced
  • 1 green bell pepper, diced
  • 1/2 onion, diced
  • 6 large eggs
  • 1/2 cup unsweetened almond milk (or your choice of milk)
  • 1 teaspoon olive oil
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon paprika
  • Salt and pepper to taste
  • Cooking spray or additional olive oil for greasing the baking dish
  1. Preheat the Oven: Preheat your oven to 375°F (190°C).
  2. Cook the Sweet Potatoes: In a large skillet, heat the olive oil over medium heat. Add the diced sweet potatoes and cook for about 5-7 minutes, or until they start to soften and brown slightly. Stir occasionally to prevent sticking. Remove from heat and set aside.
  3. Saute the Vegetables: In the same skillet, add the diced onion and bell peppers. Cook for 3-4 minutes until they start to soften. Add the chopped spinach and cook for an additional 2-3 minutes until the spinach wilts. Remove from heat and set aside.
  4. Prepare the Egg Mixture: In a large mixing bowl, whisk together the eggs, almond milk (or milk of your choice), garlic powder, paprika, salt, and pepper until well combined.
  5. Assemble the Casserole: Grease a 9×13-inch baking dish with cooking spray or a bit of olive oil. Spread the cooked sweet potatoes evenly on the bottom of the dish. Next, add the sautéed vegetable mixture on top of the sweet potatoes.
  6. Pour the Egg Mixture: Pour the egg mixture over the vegetables, ensuring that it spreads evenly.
  7. Bake: Place the baking dish in the preheated oven and bake for about 25-30 minutes, or until the casserole is set, and the top is lightly golden.
  8. Serve: Once cooked, remove from the oven and let it cool for a few minutes before slicing and serving. You can garnish with fresh herbs like parsley or chives if desired.
