Description

A cozy, set-it-and-forget-it baked oatmeal featuring firm apples, cinnamon, and maple syrup. It tastes like deconstructed apple pie and is perfect for fall brunches or meal prep.

Ingredients

Scale

6 cups (500g) old-fashioned rolled oats
3 medium firm apples (such as Granny Smith and Honeycrisp), peeled and diced
4 tablespoons (60g) unsalted butter, melted
½ cup (120ml) pure maple syrup
2 teaspoons ground cinnamon
½ teaspoon ground nutmeg
1 teaspoon pure vanilla extract
2 large eggs
1 ½ cups (360ml) milk (whole, buttermilk, or dairy-free alternative)
1 teaspoon baking powder
½ teaspoon kosher salt
Optional: ½ cup walnuts or pecans, ½ cup chopped dates or raisins, 1 tablespoon chia seeds

Instructions

Preheat oven to 350°F (175°C). Grease a 9×13 inch baking dish with butter or non-stick spray.
Peel, core, and dice the apples into ½-inch cubes. Place them in a large mixing bowl. Add optional nuts or dried fruit if using.
In a separate bowl, whisk together the melted butter, maple syrup, eggs, milk, vanilla extract, cinnamon, nutmeg, salt, and baking powder until smooth.
Pour the wet mixture over the apples. Add the rolled oats and stir until the oats are evenly coated and apples are submerged.
Pour the mixture into the prepared baking dish and spread evenly.
Bake for 45-50 minutes, or until the top is golden brown, edges are bubbling, and the center is set. Tent with foil if browning too quickly.
Let cool in the pan for at least 10-15 minutes to allow it to set before cutting into squares.

Notes

Do not use instant or steel-cut oats; old-fashioned rolled oats are required for the correct texture. Use firm apples like Granny Smith or Honeycrisp to prevent mushiness. Let the oatmeal cool completely before cutting to ensure clean slices. Can be made ahead and refrigerated overnight before baking.
