How to make blackberry basil baked oatmeal
Make the blackberry topping
Combine blackberries, sugar, lemon zest, and lemon juice in a small saucepan. Mix the cornstarch with water and a little lemon juice to make a slurry, then add it to the pan. Add about 1/4 cup water and cook over medium to medium-high heat for roughly 10 minutes, until the berries break down into a thick, jammy compote with some larger pieces remaining. If the mixture is too thin, continue cooking until thickened. Stir in chopped fresh basil, then set the compote aside to cool while you prepare the oats.
Make the baked oats
Preheat the oven to 375°F. Grease a baking or casserole dish. In a mixing bowl, mash the bananas and add applesauce. Stir in baking powder, salt, cinnamon, vanilla, and sugar, then add lemon zest and lemon juice. Mix in the milk, then fold in the oats and chia seeds until combined. Pour the oat mixture into the prepared dish and spread the cooled blackberry topping evenly over the surface. Bake for 35 to 40 minutes, until the oatmeal is set and lightly golden.
Let the bake rest for about 10 minutes before cutting so it firms up. Garnish with additional chopped basil if desired and serve warm.
Storage and reheating
Store leftovers in the refrigerator. Individual portions freeze well — wrap portions tightly and freeze. Reheat from frozen or thawed in the microwave until warmed through. This recipe is ideal for meal prep whenever you have ripe bananas on hand.
