This brown sugar baked oatmeal is a warm, comfort food breakfast that’s a perfect way to serve a crowd or to re-heat for those busy mornings.

I have been a huge fan of baked oatmeal for years. One morning, we went over to my Mom and Dad’s house for brunch and she served a big dish of warm baked oatmeal with brown sugar, fresh raspberries, strawberries, and walnuts. I was hooked! I asked her for the recipe and have been making it ever since.

- Great for meal prep and make-ahead breakfasts.

- Add your favorite fruit or nuts on top to make it your own.

What is Baked Oatmeal?
It is made with rolled oats, brown sugar (or real maple syrup), milk, eggs, vanilla, your favorite fruits and nuts and baked until warm and the oatmeal is softened. It can be topped with fresh berries. I love serving it to my family on busy mornings or when I am hosting a breakfast with friends.

Ingredients:
- Rolled Oats – The hearty base that gives structure and texture.
- Walnuts – Add crunch and nutty flavor.
- Brown Sugar – Provides warmth and sweetness.
- Baking Powder – Helps the oatmeal puff slightly.
- Milk – Creates a creamy texture.
- Eggs – Bind everything together.
- Vanilla Extract – Enhances sweetness.
- Melted Butter – Adds richness and moisture
- Fresh Fruit – Adds natural sweetness. My favorites to add are berries — strawberries, blueberries and raspberries.
- Cinnamon
- Salt
Years ago, my Dad went to get an annual check-up, and part of it included cholesterol screening. His numbers came back, and his cholesterol was way out of the healthy range. He was told he needed to change up his diet and part of it included eating oatmeal for breakfast in the morning. Oatmeal is one of the foods that is known for its cholesterol-lowering properties. When you add fresh berries and walnuts, you have a heart-healthy breakfast.

How to make Baked Oatmeal:
- Start with rolled oats. These are the old-fashioned rolled oats, not to be confused with the 5-minute oats. Stir rolled oats, brown sugar, nuts, baking powder, salt, and cinnamon, if so desired, together in a bowl. Reserve 1/4 cup of brown sugar for the topping.
- In another bowl, whisk together milk, eggs, and vanilla. In a small microwave-safe bowl, melt butter in the microwave.
- Add all ingredients together and place in an 8 or 9-inch baking dish. If you want to add fruit to the baked oatmeal, place it at the bottom of the baking dish. Some of the best fruits to use are apples, raspberries, strawberries, blackberries, etc. I would suggest using about 1 1/2 cups of fresh fruit.
- Sprinkle the remaining 1/4 cup of brown sugar all over the top of the oatmeal. This helps to create a sugary crust when it is baked. Once it is baked, top with fresh berries or your favorite fruits.
