Easy and Quick Homemade Baked Oatmeal

What is baked oatmeal and why is it different than regular old boiled oats? I had the exact same questions, my friends.

Baked oatmeal is the thicker, almost custard-like cousin, to oatmeal. How can that not be good, right? Well, it took me a couple tries to get the recipe right but I’m happy to say that last weekend I had baked oatmeal success!

You can use any fruit on the bottom. Apples are always an economical choice but use whatever is in season (peaches were on sale this week). I also used some frozen blueberries because I keep a big bag of those in my freezer. You can also try adding things like nuts, ground flax seeds, or other spices. Banana would be incredible with dulce de leche drizzled on top… ooooh.

One word of warning: I don’t like things too sweet so I used a very minimal amount of sugar here. If you want a richer, more decadent, dessert-like baked oatmeal, double the brown sugar.

Baked Oatmeal

Baked oatmeal is a new way to get your oats. Old-fashioned oats are baked in slightly sweet, custard-like mixture for a dessert-like end product.

Prep Time: 15 mins
Cook Time: 45 mins
Total Time: 1 hr
Servings: 6


  • 2 med. peaches ($1.06)
  • 1/2 cup blueberries ($0.71)
  • 1 1/2 cups milk ($0.56)
  • 1 cup plain yogurt ($0.50)
  • 1 large egg ($0.18)
  • 1/4 cup brown sugar ($0.08)
  • 2 cups old-fashioned oats ($0.34)
  • 1/2 tsp baking powder ($0.02)
  • 1/4 tsp baking soda ($0.01)
  • 1/4 tsp salt ($0.02)
  • 1 tsp ground ginger ($0.05)
  • 1/4 tsp cinnamon ($0.02)


  • Preheat the oven to 350 degrees. Clean the peaches and cut them into chunks. Place the peaches and blueberries in the bottom of an 8×8 baking dish coated with non-stick spray.
  • In one bowl, whisk together the wet ingredients (milk, yogurt, egg, sugar). In a separate bowl, stir together the dry ingredients (oats, baking powder, baking soda, salt, ginger, cinnamon). Combine the two bowls and stir until evenly mixed. Pour the mixture over the fruit in the baking dish.
  • Cover the dish with foil (to keep the moisture in and steam the oats) and place in the preheated oven. Cook for 20 minutes. Remove the foil at 20 minutes and continue to bake until the top is golden brown (about 25 minutes more).
  • Serve warm with cold milk, whipped cream, vanilla yogurt or just plain!

Two whole big peaches
These big beautiful peaches were on sale this week so I had to grab ’em up! Use whatever fruit you want. You’ll need about 2 cups worth of chopped fruit.

fruit in baking dish
Preheat the oven and coat a baking dish with non-stick spray. Use an 8×8 inch dish or something close in size. A 9×13 dish will be too big and will make a very thin, flat baked oatmeal. Not good.

In a separate bowl, combine the dry ingredients (oats, baking soda, baking powder, salt, cinnamon, ginger). Stir until evenly mixed.

uncooked side view of pan
Here’s a side view before cooking. It’s not very thick now but as it cooks, it will plump up. Cover the dish with foil and bake for 20 minutes. Then remove the foil and bake for about 25 minutes more or until the top is golden brown.

side view of cooked oatmeal in pan
See how much thicker it got? The oats soaked up all of that moisture and the milk/yogurt/eggs created an almost custard like texture. Awww-yeah.

Serve it warm or keep it in the refrigerator for a quick breakfast every day of the week!

I like a cold/hot temperature contrast so I like to pour cold milk over top.

I love oats.
