Preheat your oven to 375°F (190°C). Grease a 9x13 inch baking dish with a bit of olive oil.
In a large skillet, heat the olive oil over medium heat. Add the diced bell peppers and onion, and sauté for about 5 minutes until they start to soften.
Add the chopped mushrooms and sauté for an additional 5 minutes until all vegetables are tender.
Stir in the spinach and minced garlic, cooking for another 2 minutes until the spinach is wilted. Remove from heat and let it cool slightly.
In a large mixing bowl, whisk together the eggs, milk, salt, black pepper, oregano, and thyme until well combined.
Spread the bread cubes evenly in the prepared baking dish. Top with the sautéed vegetables, distributing them evenly over the bread.
Pour the egg mixture over the vegetables and bread, ensuring everything is well soaked.
Sprinkle the shredded cheddar cheese and grated Parmesan cheese evenly over the top of the casserole.
Cover the dish with aluminum foil and bake in the preheated oven for 25 minutes.
Remove the foil and bake for an additional 20 minutes, or until the cheese is bubbly and golden brown, and the egg is fully set.
Remove from the oven and let it cool for 5 minutes before slicing and serving. Enjoy your hearty vegetarian breakfast casserole!
