  • Author: Luciana

  • Yield: 8 servings 1x

Description

A simple, healthy weekend brunch recipe featuring old-fashioned oats, tender apples, and warm spices baked to golden perfection. This set-it-and-forget-it dish offers a crispy top and creamy center, ready in about 45 minutes.


Ingredients

Scale
  • 3 cups old-fashioned rolled oats
  • 3 cups milk (whole milk recommended)
  • 2 large eggs
  • 1/2 cup real maple syrup
  • 4 tablespoons unsalted butter, melted
  • 3 medium apples (Granny Smith or Honeycrisp), peeled and diced
  • 2 teaspoons ground cinnamon
  • 1/4 teaspoon nutmeg
  • 1/2 teaspoon salt
  • 1 tablespoon butter (for topping, optional)
  • 1/2 cup chopped pecans or walnuts (optional)

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×13 inch baking dish with butter or cooking spray.
  2. Peel and dice the apples into 1/2-inch cubes.
  3. In a large mixing bowl, whisk together the eggs, milk, maple syrup, melted butter, cinnamon, nutmeg, and salt until smooth.
  4. Add the rolled oats and diced apples to the wet mixture. Stir until oats are fully coated.
  5. Pour the mixture into the prepared baking dish and spread evenly.
  6. If using, sprinkle chopped nuts over the top and dot the surface with small pieces of cold butter.
  7. Bake for 40-45 minutes, or until the top is golden brown and the edges are bubbling.
  8. Remove from oven and let rest for 10 minutes to allow the oatmeal to set.
  9. Slice into squares and serve with extra maple syrup if desired.

Notes

For best results, use old-fashioned rolled oats, not instant or steel-cut. Let the oatmeal rest for 10 minutes after baking to ensure it sets properly. You can make this ahead by mixing ingredients the night before and refrigerating; add 5-10 minutes to baking time if baking from cold. Leftovers can be stored in the fridge for up to 5 days or frozen for up to 3 months.
