If you’ve been hanging around here long enough, then you might remember that I haven’t always been a fan of oatmeal.
Oatmeal has to have a lot of flavor, otherwise it’s too plain and boring for me. Even the instant oatmeal, as flavorful as it seems, just isn’t my thing.
And that’s why I’ve been on a mission to create those sweet, yet hearty oatmeal dishes. Have you tried my pumpkin pie oatmeal yet? It’s so warm and cozy! And since breakfast ideas are always floating around in my mind, it was time to put another oatmeal creation to good use.
And, yes, baked oatmeal definitely hits the spot for me. I just love the texture, flavor, and all-around taste. It’s like a hug on a plate, friends! This blueberry baked oatmeal recipe is my latest (and greatest) creation to add to my breakfast rotation.
Not only is this blueberry baked oats recipe a breeze to whip up (a requirement around here!), but it’s full of good-for-you ingredients and low in sugar. It’s very easy to customize this recipe depending on your tastes, too.

Can Baked Oatmeal be Made the Night Before?
Absolutely! This baked oatmeal with blueberries is perfect for meal prepping. You can make and bake this oatmeal ahead of time and then slice and serve for a quick breakfast during the week.
You can also prepare the baked oatmeal beforehand, refrigerate (cover and keep for up to two days) and then bake when ready to serve. Be sure to let the oatmeal sit at room temperature for 10-15 minutes before baking, otherwise you will need to increase cooking time.
How to Store and Reheat Baked Oatmeal
Store the blueberry oatmeal bake in the fridge — tightly covered with foil or in an airtight container — for up to five days.
To reheat, microwave a slice on high heat in 30-second increments until heated through. Or, reheat larger portions in a 350ºF oven for roughly 10 to 15 minutes.
Can You Freeze Baked Oatmeal?
You sure can! Simply let the oatmeal come to room temperature and then store in a a freezer-safe container for up to three months. When ready to serve, let thaw in the refrigerator before baking.
Can You Substitute Quick Oats for Old-Fashioned Oats?
You can, but the texture will be different. In recipes that call for old-fashioned (or rolled) oats, it provides a more chewy, nutty texture and flavor. Quick oats provide a softer, moister texture. In all of my oatmeal recipes, I use old-fashioned oats, as I prefer the hearty texture over the finer, quick oats.
Recipe Substitutions to Try
This blueberry oatmeal bake is very straightforward, so feel free to tweak the ingredients list to your liking.
- Spices: I used ground cinnamon and nutmeg, but you can play around with pumpkin pie spice, gingerbread spices, and other spice blends.
- Milk: Any kind of milk will work! Dairy or non-dairy, sweetened or unsweetened, flavored or unflavored.
- Sweetener: I used honey, but maple syrup or another liquid sweetener will work.
- Vanilla bean paste: I love the richness it adds to baked goods, but regular vanilla extract is fine too.
- Blueberries: Use fresh or frozen, or substitute another berry altogether.
How to Serve Blueberry Baked Oatmeal
