Each ingredient plays a significant role in crafting the flavor profile and health benefits of this casserole. For example, rolled oats not only provide a hearty texture but are also rich in dietary fiber, which aids in digestion and may help maintain a healthy weight. Enjoying a bowl can keep you feeling full longer. Berries not only add natural sweetness but are also packed with antioxidants, making this dish a wonderful powerhouse of nutrients. Additionally, you can easily swap regular milk for almond, soy, or oat milk to enhance its nutritional value.

How Do You Make This Delicious Baked Oatmeal Casserole?

If you’re wondering how to make this casserole, it’s simpler than you might imagine! Follow these easy steps:

Step 1

Preheat your oven to 350°F (175°C) and grease a baking dish. Greasing it will ensure your casserole doesn’t stick and makes cleanup easier.

Step 2

In a large bowl, combine the rolled oats, baking powder, and salt. Stir these dry ingredients together until mixed evenly.

Step 3

In another bowl, whisk together the milk, honey or maple syrup, eggs, and vanilla extract until fully combined. Pour these wet ingredients into the dry mixture and stir until everything is well incorporated.

Step 4

Gently fold in the mixed berries and cinnamon (if using), making sure they are evenly distributed throughout the mixture. Having an even distribution will ensure every bite has deliciousness.

Step 5

Pour the mixture into your prepared baking dish, spreading it evenly to ensure even cooking.

Step 6

Bake in the preheated oven for 25 to 30 minutes or until the top appears golden and the mixture has set. You might want to rotate the dish halfway through baking for consistent heating.

Step 7

Once done, let it cool slightly before cutting it into squares. Serve warm for an exceptional breakfast experience!
