Tips for the Best Baked Oatmeal

Use rolled oats, not quick oats, for the best texture. Quick oats can become mushy once baked.
If using frozen berries, do not thaw them first to prevent excess moisture.
For extra richness, use whole milk or a creamy plant-based milk like oat milk.
Let the baked oatmeal rest briefly after baking so it sets properly and slices cleanly.

Common Mistakes to Avoid

Overbaking is the most common issue. Keep an eye on it during the last five minutes to avoid a dry result.
Using too much liquid can make the oatmeal soggy, so measure carefully.
Skipping the baking powder will result in a dense texture instead of a light, fluffy bake.

Variations and Substitutions

You can easily customize this recipe based on what you have on hand. Swap the mixed berries for chopped apples, peaches, or bananas. Add a handful of chopped nuts like walnuts or almonds for crunch. Stir in chocolate chips for a sweeter version, or add shredded coconut for extra texture. To make it vegan, use plant-based milk and replace the egg with a flax egg.

How to Store and Meal Prep

Once cooled, store baked oatmeal in an airtight container in the refrigerator for up to five days. For meal prep, slice into individual portions and store separately. Reheat in the microwave for 30 to 60 seconds, adding a splash of milk if needed. You can also freeze portions for up to three months and thaw overnight in the fridge.

Serving and Presentation Ideas

Serve warm with a drizzle of maple syrup or honey. A dollop of Greek yogurt or a splash of cold milk pairs perfectly. For a brunch-worthy presentation, top with fresh berries and a light dusting of cinnamon just before serving.
