Why Sourdough?
Sourdough certainly seems to be growing in popularity due to the nutritional benefits. Using basic ingredients, sourdough makes one of the healthiest breads. Sourdough bread has a lower glycemic index than whole wheat bread or white bread, and the baked goods typically contain less gluten than regular yeast breads.
Sourdough is a fermented bread. Fermented bread is great for an anti-inflammatory diet, can improve gut health, and contains higher levels of vitamins, minerals, and antioxidants.
Sourdough starter discard recipes typically take no more time or effort than other similar recipes (recipes that do not contain the sourdough discard ingredient). We all know that most store-bought processed sweets contain preservatives and have almost a rubbery sort of texture, so definitely not the good stuff containing natural ingredients.
Maintaining a Sourdough Starter
I had dabbled in the world of sourdough over the years, but never fully jumped in until a client of mine had gifted me a sourdough starter. It is easiest to get started with sourdough by using an already established starter, however, it is possible to create a starter from scratch as well.
A sourdough starter takes a little bit of maintenance - feeding and discarding daily. Typically, it is a 1:1:1 ratio of an established starter, all purpose flour (unbleached) and distilled water. The consistency should be that of pancake batter, so sometimes less water is appropriate.
For a sourdough beginner, I highly recommend starting with sourdough discard recipes, such as this one. Baking with leftover sourdough discard is a great way to keep any of the extra sourdough starter from going to waste. In my opinion, the sourdough starter discard recipes are much easier to follow than recipes calling for active starter.
Recipes calling for active sourdough starter typically require multiple steps to ensure sufficient rising and proofing, which complicates the process and can be overwhelming for a beginner.
Most discard recipes, on the other hand, do not. Also, to utilize active starter you have to catch the starter when it is in fact active. This can be intimidating to someone new to sourdough or in the beginning, so getting the hang of daily feeding and utilizing the discard in recipes can be a great place to get started.

Ingredients
- Canned Apple Pie Filling (or 32 oz store bought apple pie filling)
- Old Fashioned Oats (or rolled oats)
- Flour
- Brown Sugar
- Salt
- Sourdough Discard (or active sourdough starter)
- Butter
See recipe card for quantities.
Instructions
Preheat the oven to 350 degrees. Grease a 9x9 baking dish and add the apple pie filling.
To make the apple crumble topping, first melt the butter. Next, combine the wet ingredients (melted butter and sourdough discard). In a separate large mixing bowl, mix the dry ingredients (oats, flour, salt and brown sugar). Add the wet ingredients to the dry ingredients and mix well.
Evenly cover the apples with the apple crisp topping mixture.
Bake for 30-35 minutes, or until the topping is a delicious golden brown and the apples are bubbling.
Hint - serve with a scoop of vanilla ice cream or a dollop of whipped cream.
Substitutions
During peak apple season we have an abundance of fresh apples, and in the winter months we have a pantry filled with homemade canned apple pie filling. Fresh apples can be substituted for the apple pie filling in this recipe. Honey crisp is a naturally sweet apple and a great option.
To use fresh apples - peel, slice and core 8 medium to large apples. Arrange the apples in the bottom of the greased baking dish. Sprinkle 4 tablespoons of brown sugar and 1 tablespoon of cinnamon on top of the prepared apples.
