Easy Baked Oatmeal Recipe
I love oatmeal. Quick oats, old-fashioned oats, steel cut oats. I love it with fresh fruit, dried fruit, nuts. Warm, cold…and now baked! After years of hearing about baked oatmeal, and swearing I was going to make it, I finally did. It did not disappoint!
This version includes blueberries and almonds, but those items can easily be switched out with a different fruit and nut to keep the dish interesting every week.
Baked oatmeal is a really great go-to, especially if you have portions tucked away in the fridge for the busiest of mornings!
Ingredients Needed
This baked oatmeal is a great pantry recipe! Here’s what you need:
(Scroll below to the printable recipe card for details and measurements.)
- Dry Ingredients: old-fashioned rolled oats, brown sugar, baking powder, kosher salt, and cinnamon.
- Wet Ingredients: vegetable oil, eggs, and whole milk.
- Mix-ins: blueberry and sliced almonds.
- For serving: heavy cream or maple syrup.
Recipe Tips
- Use whole old-fashioned oats for the best texture and optimal results.
- Stick with whole milk. The fat in whole milk helps hold the oatmeal together. 2% works ok, but not ideal.
- Blueberries can be fresh or frozen. If blueberries are not your thing, choose a different berry.
- Try a different nut! Swap out the almonds for pecans.

Proper Storage
- Make ahead. Assemble as directed, but instead of baking, cover it tightly and store in the fridge the night before. Let it sit at room temperature for about 30 minutes before baking or you might need to increase the bake time by a few minutes.
- Storing leftovers. Prepare as directed, allow to cool completely, then slice into portions. Store in the refrigerator in a large airtight container or in individual plastic bags, for up to 3 days.
- To reheat. Place portions in a bowl with a tablespoon of water; pop in the microwave for about 15-20 seconds or until desired temperature is reached.
- Can you freeze baked oatmeal? Yep! It will keep for up to 3 months if stored wrapped and in an airtight freezer-friendly container.

Delicious! Super easy. I used almond milk, and it worked fine. Recipe is not too sweet, and I ate it plain. Great new way to eat oatmeal.
