The Best Baked Oatmeal Recipe Ever!

This is the best Baked Oatmeal Recipe ever, and it's really healthy too, making it the perfect breakfast for meal prep or a crowd. Top with fresh berries for a well-rounded breakfast.  

Ingredients in baked oatmeal

Of course, the main ingredient in baked oatmeal is oats. I used rolled oats. Rolled oats are a whole grain. The grain has been separated from the tough outer hull then steamed and rolled flat. Because of this, rolled oats have a creamy and soft texture after they are baked.

Other ingredients you will need to make baked oatmeal are:

• Cinnamon and salt
• Baking powder
• Banana
• Coconut oil
• Milk
• Eggs
• Maple syrup
• Vanilla

I like to top my oatmeal with fresh berries but any fresh fruit, nuts, seeds or coconut will work!

How to make baked oatmeal

This baked oatmeal recipe makes six servings, but it’s easy to double or triple if you are feeding a crowd or want to meal prep healthy breakfast foods for your family. You can also serve smaller portions to a crowd then provide some sides like bacon, sausages and fresh fruit.

It only takes a little bit of prep time to make this hearty meal. Here's how to make it:

1. Mix rolled oats with baking powder, cinnamon and salt
2. Mix all the wet ingredients together in another bowl.
3. Fold the wet ingredients into the dry ingredients.
4. Add oatmeal to a greased 9×11 baking dish and bake at 350F for 45 minutes.
5. Top with berries, maple syrup or your favorite toppings.

Is baked oatmeal healthy?

Oatmeal is a fantastic breakfast food to add to your diet. It’s a whole grain that is naturally gluten free. Plus you will get all of these nutrients when you eat oatmeal:

• Fiber
• Iron
• Zinc
• Folate
• B vitamins
• Copper

While oatmeal is fairly high in carbs, it balances this out by also containing a high amount of protein, fiber and antioxidants. It is relatively low in calories and fat and will keep you feeling full for a long time.

The oatmeal itself is a very healthy choice. The toppings may change the nutritional content however. You can skip the fruit if it is too high in sugar for you or add nut butters for more protein and fat.

Instead of brown sugar which is usually found in oatmeal, I use maple syrup as a natural sweetener. You could also use other natural sweeteners like honey or date sugar.

Ingredient substitutions

If you use different kinds of oats, your cooking time will change. Steel cut oats, which are minimally processed oats, take slightly longer than rolled oats. Instant or quick oats have been cut into smaller pieces and will cut your baking time down considerably. If you use a different kind of oat, watch it carefully to ensure you don’t overbake and dry it out.

Try changing the flavor of the oatmeal by altering the spices you use. Instead of cinnamon, try pumpkin pie spice, brown sugar, ginger or give it a kick with cayenne.

If you prefer, you can use applesauce instead of the mashed banana.

You can offer lots of different options for toppings for this best baked oatmeal recipe as well. This is especially convenient if you are feeding a crowd. A bar with a variety of toppings to go with the baked oatmeal will make every guest happy. Try some of these toppings:

• Fresh or frozen berries
• Maple syrup
• Nuts such as almonds, pecans or walnuts
• Dried fruit
• Seeds like sunflower. pumpkin or chia
• Nut butters
• Coconut flakes
• Chocolate chips
• Bananas
• Jam
• Honey

Making it vegan

With two small ingredient substitutions this baked oatmeal dish can be vegan.

Use coconut milk or almond milk in place of the dairy milk.

For the egg, use a flax egg.

This recipe is already gluten free and nut free, unless you offer nuts or nut butters for optional toppings.
