The Ingredients and Their Impact


Rolled oats form the base of our granola, providing a hearty and nutritious foundation. When baked, they become wonderfully crisp, adding to the overall crunchiness. A huge key player in this recipe is pre-baking the oats for just a few minutes. This makes the final product even crunchier!

Sourdough Starter

The sourdough starter is the star of this recipe, lending a subtle tanginess that enhances the flavor profile. It also contributes to the crunchy texture, allowing us to use less sugar while still achieving a satisfying crunch.

You can use active starter or discard for this recipe, it really makes no difference! I do recommend a 100% hydration starter to maintain the proper moisture levels.

One thing to keep in mind is this sourdough recipe is not fermented for any extended length of time. So the addition of the starter is primarily for flavor and texture. You will still get some of the vitamins and minerals that call your starter home, but a lot of the digestive benefits of sourdough will not be present due to that lack of fermentation.

Maple Syrup or Honey

Both maple syrup and honey offer natural sweetness, making the granola delicious without being overly sugary. Maple syrup adds a rich, caramel-like flavor, while honey brings a floral sweetness. Both also add to the crunchy granola texture, but can be responsible for burnt oats if your oven is up too high or you leave them in too long.

Coconut Oil (or Avocado Oil)

Coconut oil helps bind the ingredients together and promotes even browning during baking. It also imparts a mild coconut flavor. Avocado oil is a great alternative, providing healthy fats and a neutral taste.

Brown Sugar

A small amount of brown sugar enhances the sweetness and helps in achieving the perfect crunch. Its molasses content adds depth to the flavor.

If you find the granola is not sweet enough for your taste, I don’t recommend increasing the sugar content. An increase could cause excessive burning of your oats. Instead, for more sweetness, consider adding more of the natural sweeteners or chocolate chips after cooling.

Vanilla Extract

Vanilla extract adds a warm, aromatic sweetness that complements the other ingredients perfectly.

Ground Flax Seed

Ground flax seed boosts the nutritional value with added fiber and omega-3 fatty acids. It also helps to bind the granola together.

Adding ground flax seed made a huge difference in the crunchiness of the granola when I was testing ingredients. Adding the flax helped me get those really big clusters loaded with crunch!


A pinch of salt balances the sweetness and enhances the overall flavor.


Cinnamon adds a warm, spicy note, making the granola comforting and aromatic. It can be omitted completely if cinnamon poses a problem in the allergy department.


Nuts add extra crunch and richness. You can use any nuts you like, such as almonds, pecans, or walnuts, for added texture and flavor. I recommend cooking the nuts with the oats for added flavor and crunch, but you may also add them raw after the granola has cooled.

Recipe Variations

While this crunchy sourdough granola recipe is delicious all by itself, you can step it up a notch by adding different flavors and additions! Experiment with what you like best, but here are some of our favorites!

Honey Oat

For a honey oat variation, simply replace the maple syrup with 1/2 cup of honey. This will make the granola even more naturally sweet and sticky.

Maple Pecan

Add more maple syrup (3/4 cup works wonderfully) and include chopped pecans in the mix. The pecans toast beautifully, adding a buttery crunch that pairs perfectly with the maple flavor.

Chocolate Coconut

Include coconut flakes and chocolate chips for a tropical twist. The coconut adds extra texture, while the chocolate chips melt slightly for a delightful indulgence. I love adding 75g of coconut flakes to the mix before baking, giving a toasted coconut flavor. I also add another handful or two to the cooled batch, along with the chocolate chips.

If you have a kiddo that is having a hard time cutting out the sugary cereal in the morning, this flavor could help! It is sweet, but not overpoweringly sweet.

Apple Cinnamon

Increase the cinnamon and add dried apple pieces. This combination creates a warm, spiced flavor reminiscent of apple pie. You can also add other warm spices such as clove or nutmeg.

Customize with Your Favorites

Feel free to add any nuts, seeds, or dried fruits you like. Chia seeds, sunflower seeds, dried cranberries, or raisins are all excellent additions. Drop a comment with your favorite combinations so we can try it out!

Storing Your Granola

To maintain the crunchiness of your granola, store it in an airtight container. A glass jar is ideal for preserving the texture and extending the shelf life. Alternatively, a ziplock bag or any airtight container will work. Keep the granola at room temperature, and it will stay fresh and crunchy for up to two weeks.
