I’m all about warm, comforting foods lately. Must be that fall weather … it’s finally arrived here in Texas. Yay!
The dropping temps are affecting all my choices lately, from clothes to meals. When it comes to my morning meal, I’m usually team breakfast sandwich, although I love oatmeal, too. Especially overnight oats, which are my favorite no fuss breakfast.
With cooler temps here to stay, I was still enjoying my fave oats … but I wanted a hot version. And one that I didn’t have to stand over the stove cooking. Have I mentioned that I’m lazy in the morning?
This Baked Oatmeal with Blueberries, Bananas, and Nuts is exactly what I’ve been craving! It’s hot, hearty, and heavenly on cold mornings … plus, it’s super healthy and beyond easy to make!
So what exactly is baked oatmeal?
It’s a breakfast casserole that’s made with everything you’d normally put into oatmeal (oats, milk, fruit, etc.). Except instead of cooking it on the stove, you bake it. Basically, an oatmeal casserole AND a lazy morning dream!
What I love about this recipe is that it fills you up, tastes amazing, and is sooo easy to make. And with all those oats and fruit, it’s very healthy.
This oatmeal is also very convenient … you can make the recipe on the weekend, then enjoy it all week long. Perfect if you like to breakfast meal prep, or if you just can’t deal with making breaking in the morning.
How to Make Baked Oatmeal
So let’s talk about how to make this blueberry baked oatmeal … it’s simple!
You’ll start by mixing together your dry ingredients (oats, cinnamon, brown sugar, baking powder, and salt) in one bowl and your wet ingredients (milk, eggs, and vanilla extract) in another bowl.
Make sure to use old-fashioned rolled oats, not instant or quick-cooking oats.
Next, add the wet ingredients to the oats. Give everything a good stir, then set it aside for a moment.
Grab a square pan, because the fruit comes next.
I chose blueberries and bananas for this baked oats casserole, but feel free to use any fruit you prefer. Raspberries, apples, strawberries, peaches, etc. would all be delicious.
If you have a crowd of picky eaters, you could skip the fruit and make plain baked oatmeal instead. Then, everyone can add their favorite toppings at the table.
You’ll place the blueberries in the bottom of your pan, then top with the bananas and nuts, reserving a bit of each for topping the oatmeal. I used walnuts here, but pecans would be good, too. Or skip the nuts altogether if you’re allergic or just don’t like them.
Pour the reserved oatmeal over the fruit next. Smooth out the top as you do, creating an even layer.
Then, sprinkle the top with your reserved blueberries and bananas.
Doesn’t that look so tasty already? I’m telling you, this is the BEST baked oatmeal!
Then, it’s time to cook your oatmeal breakfast bake.
You’ll want to bake this blueberry banana oatmeal until it’s set (no jiggling in the middle) and lightly browned on top. It should take about 40 to 45 minutes.
As the casserole cooks, the bottom gets a little custardy, but the oats on top stay chewy. Pretty much the perfect combination of textures.
And the fruit … oh yum! The blueberries become super juicy, making that bottom later even better. And the bananas add the ideal amount of sweetness.
How do you eat Baked Oatmeal?
This healthy baked oatmeal is totally enjoyable all on its own, no garnishing required. Just cut it into a square and enjoy … you can even eat it on the go.
However, I like serving it with a little Greek yogurt and extra fresh fruit. It’s pretty much the perfect breakfast!
Can Baked Oatmeal be reheated?
Meal preppers … you can make a batch of this easy baked oatmeal with fruit on Sunday, then eat it for breakfast during the week.
Simply reheat it in the microwave (or for about 20 minutes in the oven) before serving, and breakfast is done! Make sure to store any leftovers in the fridge until you’re ready to eat them.
