Ingredients

• 2 tablespoons olive oil
• 1 medium onion, diced
• 3 garlic cloves, minced
• 12 ounces vegetarian sausage, crumbled
• 8 cups baby spinach, fresh
• 6 large eggs
• 1 cup milk
• 1 cup cheddar cheese, shredded
• 1 cup parmesan cheese, grated
• 6 cups bread, cubed
• 1 teaspoon salt
• 0.5 teaspoons ground black pepper
• 0.25 teaspoons crushed red pepper flakes (optional)

Directions

Step 1

Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch casserole dish.

Step 2

In a large skillet, heat the olive oil over medium heat. Add the diced onions and cook until softened, about 3-4 minutes.

Step 3

Add the minced garlic to the skillet and cook for 1 additional minute, stirring to prevent burning.

Step 4

Stir in the crumbled vegetarian sausage and cook for 4-5 minutes, until heated through and slightly browned.

Step 5

Add the fresh spinach to the skillet, a handful at a time, and cook until wilted. Remove the skillet from the heat and set aside.

Step 6

In a large mixing bowl, whisk together the eggs, milk, salt, pepper, and red pepper flakes (if using).

Step 7

Stir in the shredded cheddar cheese, grated parmesan cheese, and cubed bread, ensuring that the bread is evenly coated with the mixture.

Step 8

Fold the sausage-spinach mixture into the bread mixture until everything is evenly combined.

Step 9

Transfer the mixture into the prepared casserole dish, spreading it out evenly.

Step 10

Bake the casserole in the preheated oven for 40-45 minutes, or until the top is golden brown and the casserole is set in the center.

Step 11

Remove the casserole from the oven and let it rest for 5-10 minutes before slicing and serving.
