This easy make-ahead breakfast recipe is ideal for feeding a crowd! Naturally gluten-free, this baked oatmeal is made with oats, eggs, berries, and a little bit of maple syrup.

Breakfast time isn’t always leisurely but that doesn’t mean you have to resort to cold cereal. Since we are almost always pressed for time during the morning routine, I love relying on hearty and healthy make-ahead breakfast recipes such as baked oatmeal that I can prep the night before or on the weekend.

To serve, simply cut out a piece and enjoy warm with a dollop of vanilla Greek yogurt. It also tastes great at room temperature or chilled. To be honest, it takes just like a cookie!


Frequently asked questions:
What is baked oatmeal?
Baked oatmeal is simply oats baked with fruit and nuts then sliced into squares to serve. You can use any nuts or fruit you have on hand. For added flavor, we love cinnamon and nutmeg but this will be just as delicious without any spices.
How do you toast nuts?
I like to toast my nuts in a 425 degree oven until fragrant, about 4-5 minutes. While we love using walnuts any type of nuts you have on hand work great including pecans or almonds. The primary goal is to add a crunchy texture and a warm, toasted flavor that pairs well with the berries and vanilla.
Can I substitute honey in lieu of maple syrup?
Absolutely! Either works but I prefer the flavor of maple syrup.
Can I use other types of fruit if I don’t have berries?
Of course! This baked oatmeal would also be delicious with peaches, cherries, nectarines, or plums.
How far in advance can I make this baked oatmeal?
It will last in the refrigerator in an air-tight container for up to 5 days.
