Ingredients
  

  • teaspoons avocado oil or olive oil
  • 1 sweet potato cubed (about 2 cups diced)
  • ½ pound ground lamb
  • ½ teaspoon garlic powder
  • ¼ teaspoon Italian seasoning
  • ¼ teaspoon crushed fennel
  • ¼ teaspoon ground sage
  • ½ teaspoon fine salt
  • Pinch black pepper
  • Pinch cayenne pepper
  • ½ small red onion diced or thinly sliced
  • 1 red bell pepper diced or thinly sliced
  • 3 cups spinach leaves
  • 8 large eggs
  • Fine salt to taste
  • Black pepper to taste
  • Sliced avocado optional for serving

Instructions
 

  • Preheat the oven to 375°F (190°C). Lightly grease a 9×9-inch baking dish with oil or non-stick cooking spray.
  • Heat the oil in a medium skillet over medium-high heat.
  • Add the diced sweet potatoes and a small pinch of salt. Cover and cook for 10–12 minutes, stirring occasionally, until slightly tender.
  • In a separate skillet, cook the ground lamb with garlic powder, Italian seasoning, fennel, sage, salt, black pepper, and cayenne until browned and fully cooked.
  • Add the red onion and bell pepper to the sweet potatoes. Cook for 3–4 minutes until softened.
  • Stir in the spinach and cook for 1–2 minutes until wilted.
  • Add the cooked lamb mixture to the vegetable mixture and stir well. Remove from heat.
  • In a large bowl, whisk the eggs with a pinch of salt and pepper.
  • Transfer the sweet potato mixture to the prepared baking dish.
  • Pour the whisked eggs evenly over the top, ensuring all ingredients are submerged.
  • Bake the Sweet Potato Breakfast Casserole for 20–24 minutes, or until the center is fully set.
  • Remove from the oven and allow it to rest for 5 minutes before slicing.
  • Serve warm with sliced avocado and your favorite hot sauce if desired.

Notes

  • Ground lamb can be replaced with beef sausage for a different flavor profile.
  • Add diced jalapeños for extra heat.
  • Serve alongside fresh fruit for a complete breakfast.
  • This casserole works well for holiday brunch spreads.
  • Avocado adds creaminess and healthy fats.
