How to Make Mexican Breakfast Casserole

Step 1: Prep the Ingredients

1. Preheat your oven to 375°F (190°C).
2. Grease a 9×13-inch casserole dish with olive oil or cooking spray.

Step 2: Cook the Sweet Potatoes

1. Heat 1 tablespoon of olive oil in a large skillet over medium heat.
2. Add the shredded sweet potatoes and cook for 5–7 minutes, stirring occasionally, until softened.
3. Spread the cooked sweet potatoes evenly across the bottom of the prepared casserole dish.

Step 3: Brown the Turkey

1. In the same skillet, add another tablespoon of olive oil.
2. Add the ground turkey and cook, breaking it into crumbles, until fully browned (about 7–10 minutes).
3. Season with ground cumin, dried oregano, paprika, cayenne pepper, salt, and black pepper. Stir well to coat the turkey evenly in the spices.

Step 4: Sauté the Vegetables

1. Push the cooked turkey to one side of the skillet and add the final tablespoon of olive oil.
2. Add the chopped onion, red bell pepper, green bell pepper, and minced garlic. Cook for 3–5 minutes, stirring occasionally, until the vegetables are softened.
3. Mix the vegetables and turkey together, then spoon the mixture evenly over the sweet potato layer in the casserole dish.

Step 5: Add the Eggs

1. In a medium mixing bowl, whisk the eggs with a pinch of salt and pepper.
2. Pour the whisked eggs evenly over the layers of sweet potatoes, turkey, and vegetables in the casserole dish.

Step 6: Bake the Casserole

1. Place the casserole dish in the preheated oven.
2. Bake for 25–30 minutes, or until the eggs are fully set and the top is golden brown.
3. Remove the casserole from the oven and let it cool for 5 minutes before slicing.

Step 7: Garnish and Serve

1. Garnish the casserole with dollops of guacamole and any additional toppings you like, such as salsa, sour cream, or chopped cilantro.
2. Slice into squares and serve warm.

Tips for the Best Mexican Breakfast Casserole

1. Shred the Sweet Potatoes Evenly: Use a box grater or food processor for consistent shredding, which ensures even cooking.
2. Adjust the Spice Level: Add more or less cayenne pepper based on your heat preference.
3. Don’t Overcook the Eggs: Keep an eye on the casserole during the last 5 minutes of baking to prevent dry eggs.
4. Make It Creamier: Add a sprinkle of shredded cheese over the top before baking for a gooey finish.
5. Use Fresh Ingredients: Fresh garlic, peppers, and sweet potatoes make a big difference in flavor.

Flavor Variations and Additions

• Cheesy Twist: Add shredded cheddar, Monterey Jack, or a Mexican cheese blend for extra richness.
• Vegetarian Option: Replace the ground turkey with black beans or crumbled tofu.
• Extra Veggies: Toss in diced zucchini, spinach, or mushrooms for more nutrients.
• Taco-Style: Serve with tortilla chips, salsa, and a dollop of sour cream for a fun twist.
