You can skip the recipe on the back of the package! Here's our best recipe—and some handy tips—for how to make baked oatmeal.

There’s nothing quite like waking up on a cold morning to a comforting breakfast that’s already been prepared. In my family, baked oatmeal is one of our favorite make-ahead breakfasts because it ticks all the boxes. It’s simple to prepare, saving you time and money each morning. Plus, baked oatmeal is healthy—and you can sweeten it up with your favorite fruit. Finally, it keeps well in the refrigerator or the freezer.

While making your morning oatmeal is simple, it’s not always foolproof. Here’s how to skip the mess and keep the comfort—with a warm pan of baked oatmeal.

How to Make Baked Oatmeal


  • 3 cups old fashioned oats
  • ½ cup packed brown sugar
  • 2 teaspoons baking powder
  • ½ teaspoon salt
  • 2 large egg whites
  • 1 large egg
  • 1 ¼ cups fat-free milk
  • ¼ cup canola oil
  • 1 teaspoon vanilla extract
  • 2 cups fruit of your choice
  • ⅓ cup chopped walnuts, optional
  • Additional fat-free milk, optional

You can add peaches and blueberries to your baked oatmeal—here’s how.

Step 1: Prep the Baking Dish

This recipe provides large servings, so keep it in mind for your next brunch with friends. Choose an 11×7-in. baking dish and coat it with cooking spray. Set it aside, and preheat the oven to 350°.

Keep that baking dish handy for these other make-ahead recipes, all perfect for 11×7 pans.

Step 2: Combine the Ingredients

In a large mixing bowl, combine the dry ingredients. Once you have mixed the oats, brown sugar, baking powder and salt, whisk in the egg whites, egg, milk, canola oil and vanilla extract. Allow the mixture to stand for about 5 minutes to thicken a bit.

Step 3: Add Your Fruit

Choose your favorite fruit and fold it into the oatmeal mixture. You can’t go wrong with any type of berry. Peaches and apples will also add some natural sweetness.

No fruit? No problem! This Amish baked oatmeal recipe is great without it.

Step 4: Bake It Up

Pour your oatmeal mixture into the prepared baking dish and sprinkle with chopped walnuts, if you’d like. Place the dish in the oven for 35 to 40 minutes, until the mixture is set and the top is slightly browned.

Oatmeal for days! Serve with additional milk and fruit and keep leftovers in the refrigerator for up to five days.
