How to Make Sweet Potato Egg Casserole Step-by-Step

1. Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking dish.
2. Heat oil in a large pan. Add sweet potatoes, bell pepper, and onion. Cook 8–9 minutes, stirring often, until tender. Stir in garlic near the end.
3. Transfer the cooked vegetables to the baking dish.
4. In the same pan, brown the turkey sausage until fully cooked. Break it into small pieces and add it to the baking dish.
5. In a large bowl, whisk eggs, milk, cheese, salt, pepper, and thyme. Mix just until combined — avoid overbeating.
6. Pour the egg mixture over the vegetables and sausage, stirring lightly to distribute.
7. Bake uncovered for 40–45 minutes until the center is set. If it browns too quickly, cover loosely with foil.
8. Let rest for 10–15 minutes before slicing.

The resting time helps the casserole hold its shape and makes serving easier.
