Preheat your oven to 350°F (175°C). Grease a 9x13-inch casserole dish with the butter.
In a large skillet over medium heat, cook the breakfast sausage, breaking it into crumbles, until browned and fully cooked. Remove from heat and drain any excess grease. Set aside.
In the same skillet, lightly sauté the diced onion until softened, about 3-4 minutes. Set aside.
In a large mixing bowl, whisk together the eggs, whole milk, salt, and black pepper until well combined.
Add the cubed bread to the greased casserole dish, spreading it out evenly.
Layer the cooked sausage and sautéed onions over the bread cubes.
Sprinkle the shredded cheddar cheese and mozzarella cheese evenly over the top.
Pour the egg and milk mixture evenly over the contents of the casserole dish, ensuring all the bread is soaked. Gently press down the mixture with a spatula if needed.
Cover the casserole dish with aluminum foil and bake in the preheated oven for 30 minutes.
Remove the foil and continue baking for another 15 minutes, or until the top is golden and the casserole is set in the center.
Remove from the oven and let it rest for 5-10 minutes before slicing and serving. Enjoy!
