One of the best things about this recipe, is that it uses such basic ingredients ... you probably already have most of them in your pantry! Here's what you'll need:
- Oats - This recipe was created using old fashioned rolled oats. Avoid instant oats and steel cut oats which both absorb liquids differently and have different cooking times.
- Cinnamon - Fragrant ground cinnamon gives this oatmeal bake a classic flavor.
- Brown Sugar - This recipe is lightly sweetened with brown sugar, which gives it a rich, warm flavor.
- Vanilla - A little vanilla extract adds another layer of tasty flavor to the recipe.
- Milk - For best results, use 2% or whole milk. Plant based milks also work great (I used soy milk).
- Eggs - The recipe calls for two large eggs, which help bind the ingredients together.
- Leavener - A bit of baking Powder helps the oats rise a bit, lightening the overall texture.
- Salt - A little kosher salt brightens and enhances all the flavors.
- Add-Ins - These Baked Oats are delicious as-is, but you can also add nuts, fruit, and more for extra flavor. Check out the Variations section below for ideas.
This recipe is naturally vegetarian, as well as gluten free. Of course, if you have an allergy, use oats specifically marked gluten free to avoid cross-contamination. For a vegan option, use plant based milk and skip the eggs, or use a vegan egg replacer.

You'll need a small bowl to beat the eggs, a large bowl to mix the oatmeal ingredients together, and an 8 x 8-inch square pan to bake the casserole. I used my beautiful Emile Henry Square Baker ... it's easy to clean and looks so pretty on the table!
How to Make Baked Oatmeal
This recipe couldn't be easier to make! You'll find a detailed recipe card below, but here's an overview of the steps:
- Mix the dry ingredients. Start by mixing together the rolled oats, brown sugar, baking powder, cinnamon, salt, and nuts (if using) in a large bowl.
- Add the wet ingredients. Next, add the milk, eggs, and vanilla extract.
- Bake. Transfer the oatmeal mixture to a square baking dish, then bake until firm and lightly browned on top.
- Serve with your favorite toppings. While this oatmeal casserole is tasty plain, it's even better served with fresh fruit, yogurt, and other toppings.
Wasn't that simple? And it tastes great, too ... you are going to love this easy Baked Oatmeal recipe!
This tasty breakfast is about as basic as it gets ... which means it's easy to customize! Here are some easy ideas to inspire you:
- Fresh Fruit - Stir in two cups of your favorite fruit along with the wet ingredients. Apples, blueberries, bananas, peaches, strawberries, raspberries, blackberries, and more will all work.
- Dried Fruit - You could also add ½ cup dried fruit, such as cranberries or raisins. A little diced crystallized ginger would also be a super tasty addition.
- Nuts - Mix in ½ cup nuts for added texture and flavor. Walnuts, pecans, pistachios, almonds, and more would all be delish.
- Chocolate - Treat yourself by stirring in ½ cup chocolate chips or chunks.
- Spices - This recipe uses cinnamon for a classic flavor, but other warm spices, like cardamom, cloves, ginger, nutmeg, or allspice, would also be delicious. You could even use a spice blend, like apple pie spice, pumpkin spice, or chai spice.
- Sweetener - Substitute ¼ cup maple syrup for the brown sugar for a natural sweeter.
- Vegan - To make this recipe vegan, simply use plant based milk and skip the eggs (or use a vegan egg replacement).
- Cups - Want to portion the recipe into single servings before baking? Bake it in a muffin tin instead of a square pan. Make sure to spray the cups with nonstick spray, and watch them closely, because the baking time will be about 10 to 15 minutes less.
As you can probably tell from the photos, Baked Oatmeal has a different texture from the creamy porridge you get when making stovetop oats. It's more of a breakfast casserole and has a firmer, bread pudding-like consistency.
You can keep things simple and serve this oatmeal as-is, or you can top it with fresh fruits, nuts, and yogurt. Some people even like it with milk. If you like a sweeter breakfast, sprinkle it with a little brown sugar or drizzle with maple syrup.
Baked Oats are a wonderful make ahead breakfast that's perfect for meal prep! Prepare the recipe on Sunday, then enjoy it all week! Refrigerate leftovers in an airtight container (they'll stay fresh for four days), then reheat gently in your microwave before eating.
You can also freeze leftovers for one to two months. I recommend wrapping individual portions separately, then storing them in a larger airtight container. That way, you can easily pull out exactly what you need.
