Ingredients
This Baked Oats recipe calls for simple, easy to find ingredients! Here's what you'll need:
- Berries - Of course, you'll want to gather some fresh fruit, and strawberries, blueberries, raspberries, and blackberries all work really well. You can easily customize the recipe by using a combination of berries, or just a one type ... it's up to you!
- Oats - You'll need old fashioned rolled oats for this breakfast bake. Avoid using instant oats and steel cut oats, because they absorb liquids differently and don't have the same cooking time.
- Nuts - Chopped nuts give the oatmeal a wonderful flavor and texture. I used walnuts this time, but pecans and other nuts may also be used. Feel free to skip the nuts if you're out, or if you have an allergy.
- Lemon - This recipe calls for fresh lemon zest, which brightens up the oatmeal casserole and pairs so well with the fruit.
- Maple Syrup - You'll use maple syrup to naturally sweeten the recipe.
- Vanilla - A little vanilla extract adds another layer of warm, cozy flavor to the recipe.
- Milk - For best results, choose 2% or whole milk. You can also use unsweetened plant based milks ... I usually make this recipe with my fave soy milk.
- Eggs - You'll need two large eggs, which are used bind the other ingredients together.
- Leavener - Baking Powder helps the oats rise as they cook, lightening the overall texture of the bake.
- Salt - A bit of kosher salt to pull all the flavors together.
This recipe is naturally vegetarian and gluten free! If you have an allergy, always read all labels carefully and make sure to use specifically marked GF oats to avoid cross-contamination. For a vegan / dairy free option, use plant based milk and skip the eggs, or use a vegan egg replacement.
You'll Also Need
You'll need a small bowl to lightly beat the egg, as well as a large bowl to mix the oatmeal ingredients together. A microplane zester is a really useful tool for zesting the lemon. To bake the oats, you'll use an 8 x 8-inch square baking dish. This Emile Henry Square Baker is my favorite ... it's looks lovely on the table, and it's easy to clean!
How to Make Berry Baked Oatmeal
This delicious Berry Oatmeal couldn't be easier to make! You'll find a detailed recipe card below, but here's an overview of the steps:
- Combine dry ingredients. Start by mixing together the rolled oats, baking powder, and salt.
- Add wet ingredients + berries. Next, you'll mix in the milk, eggs, maple syrup, lemon zest, and vanilla extract. When everything is well-combined, stir in the berries and chopped nuts. Tip: I like to reserve a few nuts and berries to decorate the top. You could even add some of these cute strawberry hearts!
- Transfer to a baking dish. Spray your baking dish with nonstick spray, then add the berry-oat mixture.
- Bake. Cook the oats until the center is set, and the top is lightly browned.
And that's all there is to it ... time to dig into your homemade Berry Baked Oatmeal!
Variations
These comforting Baked Oats are super easy to customize! Here are a few ideas to try:
- Frozen Fruit - Feel free to substitute frozen berries for the fresh.
- Other Fruits - Combine the berries with peaches, cherries, bananas, mango, apples, or other fruits.
- Nuts - I used walnuts for this recipe, but other nuts (such has pecans, almonds, pistachios, etc.) will also work great. You can skip the nuts, or substitute your favorite seeds too, if you prefer.
- Spices - For a more traditional flavor, leave out the lemon zest and add a teaspoon of ground cinnamon instead. Other warm spices, like ginger, cardamom, cloves, nutmeg, or allspice would also be tasty.
- Vegan + Dairy Free - For a vegan / dairy free version, use unsweetened plant based milk (this soy milk is my favorite) and skip the eggs (or use a vegan egg replacement).
- Gluten Free - Oats are naturally gluten free, so if you don't have an allergy any variety should work. If you do have a sensitivity, choose specifically marked GF oats to avoid cross-contamination (and read all other labels carefully).
- Cups - You can make single servings of this recipe by baking it in a nonstick muffin pan (or easy-to-clean silicone cups). Make sure to spray the cups well with nonstick spray, fill about ¾-full, and watch them closely as they bake (baking time will be about 10 to 15 minutes shorter).
Serving Suggestions
As you can probably tell from the photos, this Baked Berry Oatmeal has a different consistency than regular stovetop oatmeal! It's closer to a firm, bread pudding than the creamy porridge you may be used to.
Serve the oats hot, either plain or piled with toppings! A dollop of yogurt and extra fresh berries or nuts is always delicious, and some people even like to add a little milk. This recipe is lightly sweetened. If you find yourself craving more sweetness, drizzle maple syrup of honey over the top, or sprinkle the oats with a little brown sugar.
Storage
If you have leftovers, store them in an airtight container in your refrigerator, where they'll stay fresh for up to four days. Rewarm gently in your microwave before serving. The oats may also be frozen. I recommend dividing the bake into individual portions before freezing. That way, you can simply pull out a single serving.
This Mixed Berry Oatmeal Bake is an ideal make ahead breakfast! Make a batch on Sunday, then enjoy your cozy meal prep breakfast all week long.
