Step 1: Preheat the Oven and Prepare the Baking Dish
Preheat your oven to 350°F (175°C). Lightly grease an 8×8-inch baking dish or a similarly sized pan with butter or cooking spray. This helps prevent sticking and ensures easy serving once baked.
Step 2: Prepare the Apples
Peel the apples, remove the cores, and dice them into small, evenly sized cubes. Smaller pieces will soften more evenly and distribute sweetness throughout the bake. Set the apples aside while you prepare the rest of the ingredients.
Step 3: Mix the Dry Ingredients
In a large mixing bowl, combine the rolled oats, ground cinnamon, ground nutmeg if using, salt, and brown sugar if desired. Stir well to evenly distribute the spices and sweetener throughout the oats.
Step 4: Mix the Wet Ingredients
In a separate bowl, whisk together the milk, eggs, maple syrup or honey, and vanilla extract until fully combined. Make sure the eggs are well incorporated so the mixture bakes evenly and sets properly.
Step 5: Combine Wet and Dry Ingredients
Pour the wet mixture into the bowl with the dry oat mixture. Stir until everything is evenly moistened and the oats begin to absorb the liquid.
Step 6: Add the Apples and Optional Mix-Ins
Gently fold in the diced apples, along with the chopped nuts and dried fruit if using. Mix just until evenly distributed, taking care not to overwork the mixture.
Step 7: Transfer to the Baking Dish
Pour the oatmeal mixture into the prepared baking dish. Use a spatula or spoon to spread it out evenly and smooth the top so it bakes uniformly.
Step 8: Bake
Place the baking dish in the preheated oven and bake for 35 to 45 minutes, or until the oatmeal is set and the top is lightly golden. The center should feel firm, and a toothpick inserted into the middle should come out mostly clean.
