Introduction

This Easy Sweet Potato Egg Casserole is a hearty and flavorful dish perfect for breakfast or brunch. Packed with tender sweet potatoes, savory turkey sausage, and a cheesy egg mixture, it’s both satisfying and simple to make. Perfect for feeding a crowd or meal prepping for the week ahead.

Ingredients

• 2 tablespoons avocado oil
• 1/2 large yellow onion, chopped
• 1 green bell pepper, chopped
• 5 cups cubed sweet potatoes
• 3 garlic cloves, minced
• 1 pound turkey sausage
• 10 eggs
• 1/2 cup milk (plant-based milk can be substituted)
• 1 teaspoon dried thyme
• 1 teaspoon salt
• 1/2 teaspoon pepper
• 1/2 cup grated mozzarella cheese

Instructions

1. Step 1: Preheat your oven to 350°F (175°C). Grease a 9×13-inch casserole dish to prevent sticking. While the oven heats, chop the onion, green bell pepper, sweet potatoes, and mince the garlic.
2. Step 2: Heat avocado oil in a Dutch oven or large saucepan over medium heat. Add the chopped onion, green pepper, and sweet potatoes. Cook, stirring occasionally, for 8-9 minutes until vegetables begin to soften. Add minced garlic in the last 1-2 minutes and sauté briefly. Remove the vegetables and spread evenly in the prepared casserole dish.
3. Step 3: In the same pan, cook the turkey sausage over medium heat. Break it into small pieces as it cooks until fully cooked through. Add the cooked sausage to the vegetables in the casserole dish and stir to combine.
4. Step 4: In a mixing bowl, whisk together the eggs, milk, dried thyme, salt, pepper, and grated mozzarella cheese until smooth and well combined.
5. Step 5: Pour the egg mixture evenly over the vegetable and sausage mixture in the casserole dish. Stir gently to distribute the eggs throughout. Bake in the preheated oven for 40-45 minutes, or until the center is firm. If the top browns too quickly, cover loosely with foil during the last part of baking.
6. Step 6: Remove the casserole from the oven and let it cool for about 15 minutes before slicing and serving. This helps the casserole set and makes for easier serving.

Tips & Variations

• Swap turkey sausage for pork, chicken, or a plant-based sausage for different flavors.
• Use goat cheese or cheddar instead of mozzarella for a different cheese profile.
• Add chopped spinach or kale with the vegetables for extra greens.
• For a spicier kick, stir in a pinch of red pepper flakes or diced jalapeño when cooking the vegetables.
• To save time, roast the sweet potatoes in advance or use pre-cubed frozen sweet potatoes.

Storage

Store leftover casserole covered in the refrigerator for up to 4 days. Reheat individual portions gently in the microwave or warm in the oven at 350°F (175°C) until heated through. This casserole also freezes well—wrap tightly and freeze for up to 2 months. Thaw overnight in the fridge before reheating.
