To ensure this berry baked oatmeal recipe is delicious and nutritious, I opted to sweeten it with natural sugars from a combination of berries, maple syrup, and a little cinnamon. For this reason, it’s not overly sweet, however, you can add a little extra flavor and sweetness once it is baked by serving it with milk or yogurt, a sprinkle of cinnamon, and/or an extra drizzle of maple syrup help to make it a sweet and delicious morning meal.

FAQs

Is baked oats actually healthy?

Yes, baked oats are a healthy breakfast choice. Baked oats are made of oats, which are whole grains rich in fiber, vitamins, and minerals. When paired with fruit and a source of protein, baked oats can be a healthy and balanced meal.

Is baked oatmeal high in carbs?

Baked oatmeal is high in carbs given the primary ingredient is rolled oats, which is a source of carbohydrates. However, oats are a source of complex carbohydrates and are high in fiber, which helps to balance blood sugar, aid in digestion, and increase levels of satiety.

Why are my baked oats mushy?

The most common reason for baked oats being mushy is undercooking. Fully cooked oatmeal should be brown on top and around the edges. To ensure your baked oats are not soggy or mushy, check for doneness by inserting a knife into the center of the baked oatmeal to see if has set. If the knife comes out clean, they’re done, if the knife comes out wet, it needs more time in the oven.

Can I eat baked oats as a snack?

Absolutely. Baked oatmeal is a healthy snack on its own or paired with a source of protein and fruit for a healthy sweet snack.
