For a vegetarian option, substitute the sausage with plant-based sausage or an additional cup of roasted vegetables like mushrooms or zucchini. Feel free to experiment with different cheeses! Gruyere, cheddar, or provolone would all be delicious in this casserole. If you're making this ahead of time, assemble the casserole but do not bake. Cover tightly and refrigerate overnight. Add about 10-15 minutes to the baking time when baking from cold.

01
StepPreheat the oven to 400 degrees F (200 degrees C). Lightly grease a 9x13-inch baking dish. (5 minutes)
02
StepCombine 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. (5 minutes)
03
StepBake in the preheated oven until slightly browned, about 30 minutes.

StepMeanwhile, 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. (10 minutes)
05
StepHeat 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. (15 minutes)
06
StepGently 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. (5 minutes)
07
StepPlace roasted potatoes in the bottom of the prepared baking dish. Pour the veggie and sausage mixture evenly over top. (2 minutes)
