Need an easy breakfast that will save you time in the mornings AND is healthy for you?

Enter: baked oatmeal.

Now, oats are a serious powerhouse of nutrition. They contain fiber and a bit of protein, both of which keep you full for longer periods of time.

Not only that, but oats are also heart-healthy. They’ve been shown to help lower cholesterol- which is super relevant for my family!

Most people are just familiar with a regular bowl of oatmeal. But baked oatmeal is almost like a cake- soft, sweet, and delicious! And they’re perfect for busy mornings.

This is a healthy breakfast the whole family can enjoy.

Can you use quick oats in this recipe?

I typically use old-fashioned oats in my recipes, but you can use quick oats too if that’s what you have.

The difference is that quick oats will have a softer, less chewy texture than old fashioned oats. That’s because quick oats are chopped up smaller so they cook more quickly.

I don’t recommend steel cut oats as they cook much differently and couldn’t be used as a replacement for old fashioned oats.

Can this recipe be made vegan?

This is such a versatile recipe! There are many ways to modify this, especially to make it vegan! Here are some substitutions:

  • Use a flax egg instead of a regular egg. To make a flax egg, use 1 tablespoon ground flaxseed and 3 tablespoons water.
  • Use almond milk, coconut milk, oat milk, or your favorite non dairy milk instead of cow milk.
  • Use olive oil or coconut oil as the fat. A lot of baked oatmeal recipes use melted butter; I use olive oil in this recipe, but you could do either.
  • Use pure maple syrup instead of honey as the sweetener.

What other recipes help lower cholesterol?

Oats can certainly help lower cholesterol, but there are many other breakfasts that don’t use oats!

What can you serve with baked oatmeal?

A lot of times you can eat this by itself. I like a drizzle of maple syrup on top for extra sweetness, too.

If you need more food to go with it, like for a brunch, I recommend the following:

  • Protein (Sausage links or patties, bacon, Greek yogurt, cottage cheese, eggs)
  • Fresh fruit (Bananas, apples, oranges)

How do you make Blueberry Baked Oatmeal?

Here are the main ingredients:

  • Walnuts (Other nuts are fine too, but omit if needed)
  • Old fashioned oats
  • Ground flax
  • Milk
  • Eggs
  • Honey/maple syrup
  • Vanilla extract
  • Cinnamon
  • Baking powder
  • Salt
  • Olive oil
  • Blueberries (Fresh blueberries or frozen blueberries would work just fine- no need to thaw the frozen ones)

Start by preheating the oven to 375 degrees and greasing an 8×8 casserole dish.

In a large bowl, combine the oats, walnuts, cinnamon, baking powder, and salt.

In a medium bowl, combine the milk, eggs, honey, vanilla, and olive oil.

Pour the wet ingredients into the dry ingredients and stir to combine.

Gently fold in the blueberries using a spatula.

Pour the oat mixture into the casserole dish and bake for 35-40 minutes until the top is browned.

Once the baked oatmeal is done and cooled slightly, cut into 6 pieces and serve. Let any leftovers come to room temperature before storing in the fridge for 5-6 days.

You can also reheat it the next morning; either in the microwave, oven, or toaster oven. Sometimes I put a piece in a bowl and pour a bit of extra milk on top!

This is such a great recipe to meal prep on a Sunday afternoon and have it ready the rest of the week.
