It’s especially welcome in Fall and Winter when the best, freshest apples are in season. Also, the satisfying texture and warming spices bring some cheer to a chilly morning.

Is Baked Oatmeal Healthy?

Yes, our baked oatmeal recipe is good for you! We designed it without oil and refined sugar to make it whole food plant-based. Instead of sugar, we use unsweetened apple sauce, date syrup and dried fruit. Also, ground flax seeds replaces chicken eggs, and creamy oat milk lets us delete the dairy. Finally, almond butter (pure almond butter, with no added sugar) provides healthy fats to replace refined oil.

But what about the star ingredient, oats? Well, in short – they’re amazing. One serve of this healthy baked oatmeal has:

  • 6-7% of your daily recommended protein 
  • 5-8% of your fiber
  • 5-12% of the B-vitamins Thiamin and Pantothenic acid
  • And big doses of several essential minerals (iron, magnesium, phosphorus, zinc, copper, manganese)

The Apple of your Eye

When the weather is crisp, so are the apples! Even though there are always apples in the supermarket, they’re actually in season during Fall and Winter. This is when you’ll get the freshest, sweetest apples for baked oatmeal. We love sweet apples for this recipe, like Gala, Red Delicious, or Fuji.

So, once you decide on the apple variety, it’s time to choose the best quality fruit. Here are a few tips for finding the best of the bunch:

  • Avoid apples with soft, bruised, or decaying spots. However, don’t ditch an apple just because it’s blemished – that’s a natural part of the growing process.
  • Is it firm? Give the apple a light squeeze – don’t buy it if it’s soft and squishy.
  • Check the color, the apple varieties we mentioned above should be mostly red. Lots of color means your apple drank up plenty of sunlight, making it ripe and delicious.
  • Have a sniff – an apple in good condition has a pleasant aroma. If the scent is nasty, put it back on the pile.

How to Make Baked Oatmeal

It’s time to get your healthy baked oatmeal started. First, mix rolled oats, almonds or walnut pieces, chopped raisins, cinnamon, baking powder, and salt in a large bowl. Next, add your wet ingredients: flax egg, oat milk, apple sauce, date syrup, almond butter, and grated apple. Be sure to stir everything together thoroughly.

Now, pour the oatmeal blend into a square baking dish lined with parchment paper. Smooth the surface out with a spoon and finish the dish by topping it with apple slices and cinnamon.

To wrap things up, bake it at 375F for about 45 minutes. To test its doneness, insert a wooden skewer, which should come out clean. Finally, let it cool for a while and cut into nine pieces. Enjoy it while it’s still warm – or store it in the fridge and enjoy it through the week.
