Baked Oatmeal Recipe with Blueberries


This baked oatmeal with blueberries is jam-packed with nutrients to help you start the day off right. Not only is it high in fiber and protein, but it’s also free of processed sugars, so it will keep you energized and feeling full throughout your morning. If that didn’t convince you, you can prepare this meal the night before, which comes in handy on busy mornings where time seems to disappear.  

I always find myself skipping breakfast because I’m either rushing or lacking an appetite. Come late morning, I’m starving, and my blood sugar is low because I missed the most important meal of the day. A recipe as easy as this one will make it simpler (and more tempting) to fit in time for a well-balanced breakfast.

How To Make Blueberry Baked Oatmeal 

Preparing this tasty treat only takes about 10 minutes. You can prepare it in the morning and bake while you’re getting dressed, or do it all the night before and quickly reheat it in the morning. Just mix the wet and dry ingredients separately, combine them, and bake. Then, chow down!

Pretty much every ingredient in this delicious dish is good for you. Who needs donuts when you can have something both indulgent and good for you?

  • Old-Fashioned Oats: Oats are gluten-free and full of vitamins, minerals, and fiber. They keep you fuller longer, and unlike processed, refined grains, they aren’t just empty calories. Oats have nutrients that benefit just about every part of your body, including your heart!
  • Butter or Coconut Oil: Of course, coconut oil is the healthier option of the two. Both options will make the dish more rich and decadent, but butter is a bit more full-flavored. As they say, butter makes everything better.
  • Milk: Any milk will do the job in this recipe. You can use dairy milk, but I recommend coconut milk or oat milk for my lactose-intolerant folks. The oats are going to soak up whichever milk you choose.
  • Honey: When picking honey, look for something raw, unfiltered, and preferably local. Some “honeys” contain high-fructose corn syrup and aren’t pure honey by any means. Read the labels!
  • Pecans: Not only are pecans tasty, but they are also jam-packed with nourishing vitamins and minerals. Pecans contain calcium, potassium, magnesium, and even help lower cholesterol. Sneak these little nuts in and pat yourself on the back for feeding your family something heart-healthy!
  • Blueberries: In this dish, the blueberries are the star of the show. They’re the perfect combination of sweet and tart, especially after baking them. In all honesty, you can use a different fruit if you really want to. Baked oatmeal is pretty versatile. 
  • Bananas: The purpose of the bananas is to sweeten up the oatmeal without adding any extra sugar. They make it sweeter and creamier while also adding to the nutritional value. That sounds like a win, win to me!
  • Egg or Flaxseed: Eggs or ground flaxseed help to bind everything together and prevent it from being messy and crumbly. Both are excellent sources of protein. 

You don’t need any fancy supplies to make this recipe, either. Here’s what you’ll use:

  • 2 medium-sized mixing bowls
  • An 8×8 or 9-inch baking dish
  • Measuring cups/spoons
  • Large mixing spoon

Tips & Tricks 

  • You may have heard your mom say it as a kid, but don’t measure vanilla extract over your mixing bowl. Unlike most ingredients, if you over-pour vanilla and the excess falls into your bowl, the recipe is toast. Vanilla extract is exceptionally bold and can easily overpower any recipe if too much is added.
  • For this recipe, you can substitute old-fashioned oats for quick oats, but remember to decrease the time in the oven. Quick oats have the same nutritional value as regular oats, so don’t feel guilty if you want to make the swap.
  • Feeding a full house? This recipe can easily be doubled or tripled to add additional servings. Increase the time in the oven by about 10 minutes. If you aren’t sure whether or not it’s done, stick a toothpick in the middle and when you pull it out, it should be clean. 


Can you prepare baked oats the night before?

The answer is yes! You can leave your unbaked baking dish in the fridge overnight and bake the following morning.

Are baked oats good for weight loss?

Baked oats are a highly nutritious food that can be eaten if you’re trying to lose weight. This meal will keep you full, so you don’t feel the need to snack on sugary foods all day.
