The Best Ever Baked Oatmeal Recipe

In this video, I'm sharing a super easy baked oatmeal recipe that’s perfect for breakfast, brunch or lunch. This baked oatmeal is made in two simple stages and is packed with wholesome ingredients like oats, apples, and your choice of fresh or frozen fruit. I love how versatile this recipe is-you can easily swap out the fruits or sweeteners to suit your taste.
One thing to note: this recipe isn’t overly sweet, which I personally love. But if you prefer a bit more sweetness, feel free to add extra sugar, honey, or maple syrup-whatever works best for you!
I’ll walk you through each step, from prepping the buttermilk to baking it to golden perfection. The best part? This recipe freezes beautifully, so you can have a healthy, delicious breakfast ready to go whenever you need it. Plus, I’ll show you how to make a quick and tasty berry coulis to serve alongside.
Whether you’re enjoying it with Greek yogurt and maple syrup or on its own as a healthy snack, I think you’ll love this baked oatmeal as much as I do. Thanks for watching, and I hope you give this recipe a try!
