Preheat your oven to 350 degrees Fahrenheit.

Grease an 8x8-inch oven-safe baking dish thoroughly to prevent sticking.

In a large mixing bowl, combine the rolled oats, almond milk, beaten egg, maple syrup, olive oil, diced apples, chopped pecans, ground cinnamon, ground ginger, and ground nutmeg.

Stir the mixture well until all ingredients are evenly distributed and combined.

Transfer the mixture into the prepared baking dish.

Place the dish in the oven and bake uncovered for 35 to 40 minutes.

The oatmeal is ready when the top turns golden brown and the liquids are fully absorbed.

Enjoy the baked oatmeal warm or cold.

Serve with a dollop of Greek yogurt or a drizzle of extra maple syrup, alongside fresh fruit like berries or bananas.

Store leftovers in an airtight container in the refrigerator for up to one week.

Reheat individual portions in the microwave or oven until heated through.

For freezing, cut into squares, freeze in a single layer, then transfer to a freezer-safe container.
