Ingredients

You’ll need a few simple ingredients to make this apple pie baked oatmeal:

• Chia seeds
• Ground flax seeds
• Brown sugar
• Plain whole milk Greek yogurt
• Whole milk
• Unsweetened applesauce
• Eggs

Recipe notes and substitutions

• I like to grind flax seeds fresh, but pre-ground flaxseed works just as well.

• Honeycrisp, Gala, Pink Lady, or Fuji apples all work well in this baked oatmeal.
• For extra texture and flavor, sprinkle chopped pecans, walnuts, or raisins over the oatmeal before baking.
• I love serving a slice with a drizzle of peanut butter or almond butter for an even more filling breakfast.

Tools you’ll need

• Large mixing bowl
• Measuring cups or a kitchen scale for less cleanup
• Measuring spoons
• 9×13 baking dish

How to make apple pie baked oatmeal

Preheat oven to 350°F and lightly grease a 9×13 baking dish. Add the oats, chia seeds, flaxseed, and brown sugar to a large mixing bowl. If you’re adding protein powder, mix it in now.

Add Greek yogurt, applesauce, milk, eggs, cinnamon, cloves, and vanilla to the dry ingredients. Mix everything together in the same bowl. Add chopped apple to the mixture and give it a final stir.

Pour into the baking dish and spread evenly. Add your toppings, if using.

Cover with foil and bake for 20 minutes. Remove foil and bake for another 15-20 minutes, until set. Let cool for 10–15 minutes if eating immediately. Cool completely before storing in the fridge.

How to store and reheat

Let it cool completely, then store it in an airtight container in the fridge for up to 5 days. When you’re ready to eat, reheat individual portions in the microwave for 30 to 60 seconds. You can also eat it cold, which is great for busy mornings.

For longer storage, slice into portions and freeze in a freezer-safe container for up to 3 months.

To freeze, slice into portions and store in a freezer bag or freezer-safe container for up to 3 months. Thaw in the fridge overnight before reheating in the microwave.

You can make this without eggs, but you would need to increase the Greek yogurt to 1.5 cups to make up for the moisture loss.

Can I add protein powder?

I’ve used up to 2 servings of whey protein isolate without changing the texture. This increases the protein to 21 grams per serving.
