What Is Baked Oatmeal?
Baked oatmeal is a breakfast casserole made by combining oats, milk, eggs, a touch of sweetener, and mix-ins like fruit or nuts, then baking until set. Unlike traditional oatmeal, which is typically cooked on the stove or in the microwave, baked oatmeal is more cake-like in texture, making it easy to portion and serve. The addition of almonds and berries in this recipe adds both crunch and bursts of flavor, making the dish appealing even to oatmeal skeptics.

Ingredients
| Ingredient | Amount |
|---|---|
| Nonstick cooking spray | For coating the pan |
| Sliced almonds | 1 cup (reserve 1/4 cup, chop remainder) |
| Old-fashioned rolled oats | 2 cups |
| Baking powder | 1 tsp. |
| Ground cinnamon | 1 tsp. |
| Ground ginger | 1/2 tsp. |
| Kosher salt | 1/2 tsp. |
| Milk | 2 1/2 cups |
| Maple syrup | 2/3 cup (plus extra to serve) |
| Egg | 1 large |
| Unsalted butter, melted | 3 tbsp. |
| Vanilla extract | 2 tsp. |
| Fresh blueberries | 1 cup, divided |
| Fresh raspberries | 1 cup, divided |
| Greek yogurt | To serve |
Step-by-Step Directions
- Preheat the oven to 375°F (190°C). Lightly coat a 2-quart baking pan with nonstick cooking spray to prevent sticking.
- Toast the almonds: Line a baking sheet with foil and spread the almonds on top. Toast in the oven until lightly golden (about 7–9 minutes). Reserve 1/4 cup sliced almonds for topping; coarsely chop the remainder.
- In a large bowl, combine dry ingredients: oats, chopped almonds, baking powder, cinnamon, ginger, and salt.
- In a medium bowl, whisk wet ingredients: milk, maple syrup, egg, melted butter, and vanilla extract.
- Pour the wet mixture into the dry mixture and stir to combine. Add about 3/4 of the blueberries and raspberries and fold gently to distribute.
- Transfer mixture to the prepared baking pan. Top with remaining berries and reserved sliced almonds.
- Bake for 55–60 minutes, until the oatmeal is set and golden brown on top.
- Let the oatmeal cool for about 10 minutes before serving; this allows it to firm up for easier slicing or scooping.
- Serve warm with additional maple syrup and a spoonful of Greek yogurt for a creamy finish.
Tips for the Best Baked Oatmeal
- Toast your nuts for maximum flavor and crunch.
- Let your oatmeal rest before serving for a better texture.
- Use any berry you like: strawberries, blackberries, or even a mix! Cut larger berries (like strawberries) into 1/2-inch pieces for even baking.
- For richer flavor, use whole milk; for a lighter casserole, choose your favorite non-dairy milk.
Ingredient Substitutions & Variations
- Swap almonds for pecans, walnuts, or leave out for a nut-free option.
- Try other fruits: Chopped apples, pears, or bananas work well.
- Change up spices: Cardamom, nutmeg, or pumpkin pie spice offer new flavors.
- Use quick oats for a softer texture or old-fashioned rolled oats for a heartier bite.
- Sweeteners: Replace maple syrup with honey or brown sugar if preferred.
Serving Suggestions
- Top baked oatmeal with Greek yogurt or a drizzle of cream for added richness.
- Serve with fresh berries and an extra splash of maple syrup.
- The casserole pairs perfectly with coffee, tea, or fresh orange juice on weekend mornings.
- Make it ahead: Refrigerate unbaked oatmeal overnight, then bake fresh in the morning!
