Baked oatmeal has become a go-to of ours. It’s easy to make, great for meal prep, and also makes for a delightful and scrumptious breakfast or brunch. Paired with our Turkey Apple Sausage Patties it makes for a nicely balanced meal to start the day. While we prefer to serve baked oatmeal warm, it also tastes great cold if you need a breakfast quick.  Add this healthy breakfast recipe to your weekend meal prep session and you’ll have a hearty breakfast bursting with juicy blueberries ready for the week.

How to make Blueberry Baked Oatmeal

• Step 2: In a bowl, combine all of the ingredients and mix.
• Step 3: Transfer to the baking dish. Top with a few additional frozen berries and sliced almonds, if desired.
• Step 4: Bake for 30-35 minutes or until center is set. 
• Step 5: Let it sit for 10 minutes before serving.
• Step 6: Top with whipped topping or plain yogurt and a drizzle of maple syrup if you please.

Can you freeze Baked Oatmeal?

Absolutely. Oatmeal bakes are perfect for freezing and enjoying as a future meal. We love to double the recipe and stash one away in the freezer. You can also make them into oatmeal cup muffins as we did in our Zucchini Banana Baked Oatmeal Cups.

Can fresh blueberries be used instead of frozen?

You sure can. In fact, you can use any berries you like or have on hand. Strawberries, blackberries, raspberries, or a mix like we did in our Mixed Berry Baked Oatmeal recipe.

How to make Blueberry Baked Oatmeal nut-free and dairy-free.

Simply omit the almonds for a nut-free option. For dairy-free, we like to use unsweetened almond milk and melted coconut oil in place of the butter.
