Equipment

  • 1 8X8 Baking dish
  • 1 Medium mixing bowl
  • 1 large mixing bowl

Ingredients
  

Ingredients:

  • 2 cups rolled oats
  • 1 tsp. baking powder
  • 1 tsp. cinnamon
  • ½ teaspoon nutmeg
  • ¼ tsp. salt
  • 1 ¾ cups almond milk
  • 2 large eggs
  • ⅓ cup pure maple syrup
  • 2 teaspoons pure vanilla extract
  • 1 ½ cups gala apples chopped into ½ inch cubes
  • ½ cup chopped pecans or other nut

Instructions
 

Instructions:

  • Preheat your oven to 375 degrees F and generously grease an 8 x 8 inch baking dish with butter.
  • Add the rolled oats, cinnamon, nutmeg, salt, and baking powder to a large mixing bowl.
  • Stir the dry ingredients together until they are evenly combined.
  • In a separate small bowl, add the almond milk, eggs, maple syrup, and vanilla extract.
  • Whisk the wet ingredients until the eggs are fully incorporated, and the mixture is smooth.
  • Pour the wet ingredients into the bowl with the dry ingredients.
  • Stir until the oat mixture is evenly moistened and fully combined.
  • Add the diced apples and chopped pecans into the mixture.
  • Fold in the apples and pecans until evenly distributed.
  • Transfer the oatmeal mixture to the prepared baking dish and spread it into an even layer. Place the baking dish on the center rack of the preheated oven and bake uncovered for 40 to 45 minutes, or until the oatmeal is set and lightly golden brown.
  • Remove the baked oatmeal from the oven and let it rest for 5 minutes before serving warm with maple syrup, Greek yogurt, or your favorite toppings.

Notes

Ingredient Substitutions
  • Rolled oats are the best choice because they maintain their texture during baking, but quick oats can be substituted if you prefer a softer consistency. Substitute gluten-free rolled oats to make the recipe gluten-free.
  • Honeycrisp, Gala, Fuji, Pink Lady, Granny Smith, or Braeburn all work well as apple varieties to be used in this recipe. Or, swap in diced pears for a different fall flavor.
  • Replace almond milk with whole milk, 2% milk, Oat milk, Soy milk, or Coconut milk.
  • Honey, Brown sugar, and coconut sugar can be used in place of maple syrup.
  • If you’re not a fan of pecans, walnuts, sliced almonds, or even sunflower seeds provide great texture. Or simply leave the nuts out for a nut-free breakfast.
 
Recipe Variations
  • Apple Crisp Baked Oatmeal: Top the oatmeal with a buttery cinnamon oat streusel before baking for a crisp, crumbly topping that tastes just like apple crisp.
  • Apple Walnut Raisin: Mix in chopped walnuts and raisins for extra texture and natural sweetness.
  • Caramel Apple: Drizzle warm caramel sauce over the baked oatmeal before serving for a decadent breakfast or brunch.
  • Protein Packed: Add vanilla protein powder to the wet ingredients or stir in Greek yogurt before serving for a protein boost.
  • Cranberry Apple: Mix dried cranberries into the batter for a tart, festive twist that’s perfect for fall and the holidays.
  • Double Apple: Use diced fresh apples and stir in unsweetened applesauce for even more apple flavor and extra moisture.
  • Apple Pie Cheesecake: Swirl softened cream cheese into the oatmeal before baking for a rich, cheesecake-inspired variation.
  • Dessert Style: Serve warm with a scoop of vanilla ice cream and a drizzle of caramel sauce for a comforting dessert that tastes just like apple pie.
 
Chef Tips
  • Choose firm apples that hold their shape during baking, such as Honeycrisp, Fuji, Gala, Pink Lady, or Granny Smith.
  • Dice the apples into evenly sized pieces so they cook uniformly.
  • Toast the pecans before folding them into the batter to deepen their flavor.
  • Don’t overmix the oatmeal mixture or it can become dense.
  • For crisp, caramelized edges, bake in a ceramic or glass baking dish.
  • Let the baked oatmeal rest for 10 minutes before slicing for cleaner portions.
  • Add extra cinnamon sugar on top before baking for a lightly caramelized crust.
If you’re serving this for guests, reserve a handful of diced apples and chopped pecans to scatter over the top just before baking.
Finish the casserole with a light sprinkle of coarse cinnamon sugar. The apples stay slightly firmer, the pecans toast beautifully, and the golden top gives the finished dish a bakery-quality appearance.
 
Serving Suggestions
For holiday brunches, create a breakfast board featuring slices of baked oatmeal, bowls of Greek yogurt, maple syrup, toasted nuts, fresh berries, apple butter, whipped cream, and warm cinnamon apples. Let everyone customize their own serving.
  • Serve warm with a dollop of vanilla Greek yogurt and a sprinkle of granola for a creamy, protein-packed breakfast.
  • Top with chopped toasted pecans or walnuts for added crunch and drizzle with warm maple syrup or honey for extra sweetness.
  • Pair with crispy bacon or breakfast sausage for a hearty morning meal.
  • Add a side of scrambled eggs to create a balanced breakfast.
  • Serve with fresh berries or sliced bananas for a pop of freshness.
  • Dust with a little extra cinnamon before serving for an apple pie-inspired finish.
 
Beverage Pairing
  • A cinnamon latte or medium roast coffee complements the warm apple and spice flavors beautifully.
  • Chai tea or hot cinnamon spice tea enhances the cozy apple pie flavor.
  • Fresh apple cider or freshly squeezed orange juice adds a bright, refreshing contrast.
  • Cold whole milk, oat milk, or vanilla almond milk makes a simple and satisfying pairing.

Recipe FAQs
Can I make baked oatmeal ahead of time?
Yes. It’s one of the best make-ahead breakfast recipes and reheats beautifully throughout the week.
Can I use steel-cut oats?
No. Steel-cut oats require much more liquid and a significantly longer cooking time.
Can I double the recipe?.
Yes. Bake it in a greased 9×13-inch baking dish and increase the baking time by about 5 to 10 minutes.
