Ingredients

1 pound sweet potatoes, peeled and cut into 1/2-inch cubes
3 tablespoons extra-virgin olive oil, divided
2 teaspoons kosher salt, divided
1 teaspoon garlic powder
1 teaspoon freshly ground black pepper, divided
1/2 cup diced onion
1/2 cup diced red bell pepper
4 cloves garlic, minced
1 pound bulk regular pork sausage (such as Jimmy Dean®)
1 cup baby spinach leaves
1/2 cup shredded mozzarella cheese
1 tablespoon minced fresh rosemary
10 large eggs
2 tablespoons milk

Directions

1 Preheat the oven to 400 degrees F (200 degrees C). Lightly grease a 9x13-inch baking dish.
2 Combine sweet potatoes with 2 tablespoons olive oil, 1 teaspoon kosher salt, garlic powder, and 1/2 teaspoon black pepper on a large baking sheet in a single, even layer; toss to coat well.
3 Bake in the preheated oven until slightly browned, about 30 minutes.
4 Meanwhile, heat remaining 1 tablespoon olive oil in a large skillet over medium-high heat. Add onion and red pepper; cook and stir until translucent, 2 to 3 minutes. Add garlic and stir for 1 more minute. Transfer mixture to a medium mixing bowl.
5 Heat the same skillet over medium-high heat. Add sausage; cook and break apart with a spatula until cooked through, 5 to 7 minutes. Drain sausage and add to the bowl with the veggie mixture. Add spinach, mozzarella cheese, and rosemary to the mixture.
6 Gently whisk eggs, milk, and remaining kosher salt and black pepper together in a bowl until well combined. Pour over the sausage and veggie mixture and gently toss to combine.
7 Place roasted potatoes in the bottom of the prepared baking dish. Pour the veggie and sausage mixture evenly over top.
8 Bake, uncovered, in the preheated oven until eggs are set in the center, about 50 minutes. If the egg mixture starts to brown, put a loose sheet of aluminum foil over the baking dish to cover it.
