Baked Oatmeal

Baked OatmealHeidi Swanson

I've enjoyed oats a thousand different ways in my life, and this is my favorite. A layer of fruit lines the base of a well-buttered baking dish. The fruit is then topped with a blend of rolled oats, nuts, and spices. A wet mixture of milk, egg, melted butter, and vanilla is drizzled over the dry ingredients before baking to a golden-topped, fruit-scented finish. Be sure to use rolled oats and not instant oats.

Ingredients

Serves 6 generously, or 12 as part of a larger brunch spread

2 cups/7 oz/200 g rolled oats
1/2 cup/2 oz/60 g walnut pieces, toasted and chopped
1/3 cup/2 oz/60 g natural cane sugar or maple syrup, plus more for serving
1 teaspoon aluminum-free baking powder
1 1/2 teaspoons ground cinnamon
Scant 1/2 teaspoon fine-grain sea salt
2 cups/475 ml milk
1 large egg
3 tablespoons unsalted butter, melted and cooled slightly
2 teaspoons pure vanilla extract
2 ripe bananas, cut into 1/2-inch/1 cm pieces
1 1/2 cups/6.5 oz/185 g huckleberries, blueberries, or mixed berries

Preparation

  1. Step 1

    Preheat the oven to 375°F/190°C with a rack in the top third of the oven. Generously butter the inside of an 8-inch/20cm square baking dish.

    Step 2

    In a bowl, mix together the oats, half the walnuts, the sugar, if using, the baking powder, cinnamon, and salt.

    Step 3

    In another bowl, whisk together the maple syrup, if using, the milk, egg, half of the butter, and the vanilla.

    Step 4

    Arrange the bananas in a single layer in the bottom of the prepared baking dish. Sprinkle two-thirds of the berries over the top. Cover the fruit with the oat mixture. Slowly drizzle the milk mixture over the oats. Gently give the baking dish a couple thwacks on the countertop to make sure the milk moves through the oats. Scatter the remaining berries and remaining walnuts across the top.

    Step 5

    Bake for 35 to 45 minutes, until the top is nicely golden and the oat mixture has set. Remove from the oven and let cool for a few minutes. Drizzle the remaining melted butter on the top and serve. Sprinkle with a bit more sugar or drizzle with maple syrup if you want it a bit sweeter.

Cooks' Note

Although I love this huckleberry version, feel free to substitute your favorite in-season berries, or any other fruit for that matter. Another version I love is made with plump, amaretto-soaked golden raisins in place of the berries and sliced almonds in place of the walnuts.

  • I made this using blueberries and rum soaked raisins and dried cranberries. I also subbed the milk for almond milk and sugar free maple syrup to lower the calories. Although it doesn’t call for it, I added 1 cup of coconut flour so it would have a cake like consistency. It was so good. I take a helping to work for a filling breakfast and my son heats it up with a scoop of ice cream at night for a snack before bed. It is filling and delicious. I will absolutely make variations of this again.

  • I make this every week often adding unsweetened coconut. There are countless ways to modify.

  • Also, this can be simplified method-wise. Do it just like a muffin or cake recipe: all the wet ingredients mixed together (including mashed banana), then the dry ingredients (including blueberries or other berries), then mix the two together and pour into baking dish.

  • Good basic recipe. You can amend it as you please, of course. No need for the added sugar, in my mind, with the fruit.

  • Love this! I’ve used rum soaked and apple brandy soaked golden raisins in place of the the berries, pecans instead of walnuts and coconut sprinkled on top too. Today I added some dried pears briefly soaked in apple brandy. I think it’s going to be delicous!

  • Really enjoyed this as a comfort breakfast option. Didn't have the fruit mentioned in the recipe but saw someone mention in the reviews of using apples and raisins so I diced two apples and used Eden dried cranberries with no sugar (sweetened with unsweetened apple juice). Turned out great and had that fall feel with the apples/cranberries.

  • I absolutely love this recipe. It is so easy to make for a group, and addictively delicious! In the winter I make it with frozen berries. It is great any time of year.

  • I've been making this for five years. I'd love a suggestion on how to be able to serve as a square rather than the soft on the bottom creation it often becomes - always tasty just looking for better presentation. longer baking at lower temp? The reviewer who suggested mashing the banana into the oat meal suggest this may help too.

  • I love this recipe. It is perfect for my crazy week day mornings when I leave the house at 4:30. I make this on Sunday and divide it up among several containers. When I get to work I pop it in the microwave and it's delicious. I also don't add the sugar as the fruit is sweet enough. I mash the bananas into the oatmeal since I prep ahead. This way they don't get slimy.

  • P.S. to the comment I just wrote: delish when coconut oil is substituted for butter.

  • This is my 4th time to make this; the recipe is a keeper! I omit the sugar, as the bananas and blueberries are sweet enough. I've also made this with chopped apples and raisins (and a bit of stevia). Really, I think any fruit would work.

  • First time I made this I did exactly as the recipe called for (different fruit however) and it was excellent. But my family is a bunch of health nuts and much prefer steel cut oats. I found a comment from a previous reviewer and tried as recommended (3/4 oats and 3 cups milk). It was horrible. It spent 2 hours on the oven trying to reduce the milk because it was too much and it came out a sickly mess. Here are the changes I recommend based on my experience with making this with steel cut oats: keep everything the same but reduce the oats to 1 cup, assemble everything but the fruit for overnight oats (since steel oat are MUUUCH more chewy and take a very long time to cook), in the morning preheat the oven to 400F. Prepare the baking dish and add the fruit and oats. Bake 40-45 minutes, or until liquid is fully absorbed. Cool for 10 minutes. Enjoy!
