A cozy, make-ahead breakfast loaded with sweet potatoes, eggs, sausage, and cheese. This hearty casserole is perfect for meal prep or weekend brunch.

Ingredients

For the Base:

3 garlic cloves, minced

1 lb uncooked turkey sausage

5 cups sweet potatoes, cubed (1-inch pieces)

1 green bell pepper, diced

½ large yellow onion, finely diced

2 tbsp avocado oil (or olive oil)

For the Egg Mixture:

10 large eggs

½ cup whole milk (or plant-based alternative)

½ cup grated mozzarella cheese (or preferred cheese)

1 tsp salt

1 tsp dried thyme

½ tsp black pepper

Instructions

Preheat Oven & Prep Dish
Preheat oven to 350°F (175°C). Grease a 9×13-inch casserole dish and chop all vegetables.

Cook the Vegetables
In a Dutch oven or large pan, heat avocado oil. Add sweet potatoes, onion, and bell pepper. Cook for 8–9 minutes until slightly tender.
Stir in garlic for the last 1–2 minutes. Transfer veggies to the casserole dish.

Cook the Sausage
In the same pan, cook turkey sausage until browned and fully cooked. Break it into small pieces as it cooks.
Add sausage to the casserole dish and combine with vegetables.

Prepare Egg Mixture
In a bowl, whisk together eggs, milk, cheese, salt, thyme, and pepper until well mixed.

Assemble & Bake
Pour egg mixture evenly over the sausage and veggie mix. Gently stir to combine.
Bake uncovered for 40–45 minutes or until the center is set.
Cover loosely with foil halfway through if the top browns too quickly.

Cool & Serve
Let casserole cool for 10–15 minutes before slicing and serving. This helps the eggs set and makes for cleaner portions.

Notes

Make-Ahead Tip: Assemble the casserole the night before, cover, and refrigerate. Bake in the morning after bringing to room temp.

Storage: Refrigerate leftovers in an airtight container for up to 4 days.

Freezing: Wrap individual portions and freeze for up to 3 months. Reheat in the microwave or oven.

Serving Suggestions: Pair with fruit salad, avocado slices, toast, or a light green salad.
