• 2 cups milk (dairy or unsweetened non-dairy)
• 1 tablespoon olive oil
• 1 teaspoon garlic powder
• 1 teaspoon dried thyme or oregano
• ½ teaspoon smoked paprika
• Salt and pepper, to taste

Vegetables (customizable):

• 1 cup baby spinach, chopped
• 1 cup mushrooms, sliced
• 1 small onion, finely chopped
• 1 red bell pepper, diced
• 1 small zucchini, diced

For the Topping:

• 1 cup shredded cheddar cheese (or mozzarella)
• Fresh parsley or chives, chopped, for garnish

How to Make Hearty Savory Oatmeal Bake

Preheat oven to 375°F (190°C). Grease a medium baking dish with olive oil. In a skillet, sauté onion, mushrooms, bell pepper, and zucchini until softened; add spinach last to wilt. In a large bowl, whisk eggs, milk, garlic powder, thyme, smoked paprika, salt, and pepper. Stir in rolled oats and sautéed vegetables. Pour mixture into prepared baking dish. Sprinkle with shredded cheese. Bake 35–40 minutes until set and golden on top. Let rest for 10 minutes before slicing. Garnish with parsley or chives and serve warm as a main or side dish.

Instructions:

1. Preheat the Oven:
   Set your oven to 375°F (190°C). Lightly grease a medium baking dish with olive oil or nonstick spray to prevent sticking.
2. Prepare the Vegetables:
   Heat a skillet over medium heat with a drizzle of olive oil. Add onion and sauté for 2–3 minutes until softened. Stir in mushrooms, red bell pepper, and zucchini. Cook for another 5 minutes, stirring occasionally, until vegetables release moisture and begin to caramelize. Add chopped spinach last and cook for 1 minute until just wilted. Remove from heat.
3. Mix the Egg and Oat Base:
   In a large mixing bowl, whisk together eggs, milk, garlic powder, dried thyme, smoked paprika, salt, and pepper. This custard-like mixture will bind the oats and vegetables together while baking.
4. Combine Ingredients:
   Stir rolled oats into the egg mixture, then fold in the sautéed vegetables until evenly distributed. The oats will absorb the liquid and soften during baking, creating a fluffy, casserole-like texture.
5. Assemble the Bake:
   Pour the mixture into the prepared baking dish, spreading it evenly with a spatula. Sprinkle the top with shredded cheddar cheese (or mozzarella for a milder flavor).
6. Bake the Dish:
   Transfer the dish to the oven and bake for 35–40 minutes, until the center is set and the top is golden brown with bubbling cheese. If needed, broil for 1–2 minutes for extra browning.
7. Cool and Serve:
   Remove the dish from the oven and let it rest for 10 minutes before slicing. This helps the bake firm up and makes cutting easier. Garnish with fresh parsley or chives for a bright finish. Serve warm as a main course with salad or as a hearty side dish with soup.
