Baked Oatmeal
If your mornings feel like a whirlwind, Baked Oatmeal might just become your new best friend. It’s warm, hearty, and packed with cozy flavors that make it feel like a little morning hug in every bite. Plus, it’s so easy to whip up that you might find yourself skipping the store-bought cereals altogether.
This recipe is everything I love in a breakfast—simple ingredients, easy prep, and a little versatility to make it your own. Whether you’re a fan of sweet bursts of raisins, the crunch of slivered almonds, or the juicy pop of apples, there’s a little something for everyone in this dish.
And the best part? You can make it ahead and reheat it during the week for those busy mornings. Or, if you’re like me, it’s equally perfect for a slow, lazy weekend breakfast with a steaming cup of coffee. Trust me, your kitchen is about to smell amazing!
Oats are delicious to cook with various sweet recipes such as overnight oats, oatmeal, sweet and warm apple crisp, strawberry coconut breakfast casserole, and these crumbly apple crisp bars.

Ingredients
The full printable recipe card with measurements and instructions is found at the bottom of the post.
- Sugar: I use regular granulated white sugar for this baked oatmeal recipe, but feel free to substitute with liquid sweetener or coconut sugar.
- Oil: Vegetable oil makes baked oatmeal moist and full of soft flavors.
- Eggs: Two whole eggs are used to bring everything together and make sure it bakes well.
- Milk: A little bit of dairy milk is used for these oats. You can use your favorite kind of dairy-free milk.
- Vanilla: Pure vanilla extract is rich and aromatic and a perfect addition to this cinnamon-baked oatmeal.
- Oats: I use “large flake oats” or old-fashioned oats for this oatmeal because they cook well and soak up all the flavors.
- Baking Powder: You will need some baking powder to make sure everything rises and sticks together.
- Salt: A little bit of sea salt balances everything out!
- Cinnamon: Ground cinnamon is rich, spicy, aromatic, and a great addition to these sweet oats.
- Almonds: Slivered almonds give this oat recipe a light nuttiness and crunch in addition to some protein.
- Raisins: Sweet plump raisins are mixed throughout the oats to create baked oatmeal full of sweet surprises.
- Apples: Freshly chopped apples allow this baked oatmeal to have natural sweetness. Any kind of apples, such as Granny Smith, Gala, Honeycrisp, Fuji, etc., will work.

Follow along to learn how to make baked oatmeal.
- Step One: Preheat oven to 350°F.

Variations and Substitutions
- Add More Fruit: Take this baked oatmeal to the next level with extra fruit! Try pears, strawberries, blueberries, peaches, bananas, or even a handful of dried cranberries for a burst of sweetness.
- Sweeten It Up: Sprinkle in chocolate chips, white chocolate chunks, or butterscotch chips for a dessert-inspired twist.
- Switch Up the Nuts: Not a fan of almonds? Chopped pecans, pistachios, walnuts, or even hazelnuts are great alternatives that bring their own unique flavor and crunch.
- Dairy-Free Option: Swap out the milk for almond milk, oat milk, or coconut milk to make it dairy-free.
- Lower the Sugar: Cut back on the sugar and add a little maple syrup or honey instead for a more natural sweetness.
- Spice It Up: Play around with spices like nutmeg, cardamom, or even pumpkin pie spice for a fun flavor boost.
- Texture Tweaks: Prefer a softer texture? Use quick oats instead of old-fashioned oats for a smoother consistency.
What To Serve With This
- Fresh Fruit: Serve it with a colorful fruit salad or a bowl of fresh berries for a refreshing side.
- Yogurt: A dollop of homemade plain yogurt or Greek yogurt on top adds a creamy, tangy contrast. For a little extra sweetness, drizzle with honey or maple syrup.
- Egg Dishes: Pair it with spinach and cheese egg muffins, scrambled eggs, or a hearty breakfast casserole for a well-rounded meal.
- Coffee or Tea: A steaming cup of coffee or a soothing mug of tea is a must to enjoy with this comforting breakfast.
- Breakfast Meats: For those who like a savory twist, bacon, sausage, or veggie breakfast patties complement the sweetness of the oatmeal.
Storage Instructions
- Refrigerator: Let the baked oatmeal cool completely before transferring it to an airtight container or covering the baking dish tightly with plastic wrap or foil. It will stay fresh in the fridge for up to 3 days.
- Freezer: For longer storage, slice the baked oatmeal into individual portions and wrap each piece tightly in plastic wrap, then place them in a freezer-safe bag or container. Freeze for up to 3 months.
- Reheating: To reheat, simply pop a portion in the microwave for 30–60 seconds or warm it in the oven at 350°F for about 10 minutes. If reheating from frozen, let it thaw overnight in the fridge first.

This sounds so very delicious. I love oatmeal so I know I’d really love this!
This looks so good because I love oatmeal! Printed and pinned.
I like to make my baked oatmeal in muffin tins with paper liners. My recipe makes a dozen so I can put the rest in the freezer and take them out as needed.
This sounds amazing! PINNED! 🙂

Healthy and delicious! I am always on the lookout of using oats in my diet rather than the same old fashioned way. This looks inviting!
This oatmeal casserole sounds delicious with the apples, raisins, and spices in it. I think it would be a great start to our day.
A friend of mine made an oatmeal casserole but I didn’t enjoy it as much as just having the oatmeal with some yogurt.
Interesting idea to make a casserole out of oatmeal
I haven’t enjoyed an oatmeal casserole before but I think that it would be great to make one to have on hand for quick daily breakfasts for a couple of days.
I think I’d enjoy oatmeal a little more this way!
