Blueberry Baked Oatmeal is an easy, healthy breakfast you can prep the night before. Perfect for a stress-free weekday breakfast!

Blueberry Baked Oatmeal Recipe (1)

We love oatmeal around here – in baked oatmeal, in overnight oats, in breakfast cookies… I have a few versions of baked oatmeal here on the blog that are super delicious already, but a blueberry one was definitely missing!

This works great with both fresh or frozen blueberries, so it’s a wonderful make ahead breakfast all year round. You can even switch up the berries if you’re feeling adventurous – raspberry is a firm favorite over here, too!

You can prep this the night before for an easy morning, but if you want to bake it right away, I’ve included some instructions below.

Ingredient notes

  • Eggs:Instead of whole eggs, you can also use 3 large egg whites. I have never tried making a vegan version without eggs, so I can’t recommend any substitutions here.
  • Sweetener:Use 1-2 tablespoons of a Stevia or Erythriol blend to sweeten the oatmeal if you want to make it sugar-free.
  • Oats: I always use old fashioned. Quick oats work OK, too, they’re just a little moister. Please do not use instant oats.
  • Blueberries: I always use frozen because they’re more budget-friendly. You can use fresh if you want to.
  • Milk: Cow’s milk or unsweetened almond work best here.

Recipe tips

  • No grey oatmeal:I usually don’t stir the blueberries into the oats, but but sprinkle them on top, to keep the oatmeal from turning all weirdly grey.
  • Bake without soaking overnight: Make sure to use quick-cooking oats, let the assembled oats sit on the counter for 10 minutes while you preheat the oven, and live with the fact that it’s a little less cake-like ?

Serving suggestions

Some of my family members prefer theirs in a bowl with milk and use a spoon to eat their oatmeal.

Others like it cake-style, with a few spoonfuls of Greek yogurt and a fork. And one particular tiny person might like it best cold, slathered with peanut butter ?

I let them do whatever they want, as long as they get their own stuff and put it back again after breakfast, ha!

I just use a large bowl, measure out all my ingredients, dump them in the bowl and stir with a wooden spoon until they’re combined. Well, that’s pretty much the recipe ?

Blueberry Baked Oatmeal Recipe (11)

I’m using a 7×11 rectangular baking dish. You could also do individual muffin cups! I prefer layering my baked oatmeal vs stirring the blueberries into the whole mix. This a) helps prevent blueberries sticking to the bottom of the baking dish like glue and b) doesn’t turn your baked oatmeal a ghastly grey color.

First, I spread half the oat mix in the bottom of the baking dish. It’s smart to just lightly grease the dish, but I often forget.Then I layer on most of the blueberries.

THEN I add the rest of the oat mixture…
