Expert Tips for Caramelized Onion Sourdough Biscuits
-
Chill Your Butter: Ensure the butter is very cold before cutting it into the flour. This is key to achieving those flaky layers in your biscuits.
-
Don’t Over-Mix: Gently fold the dough. Over-mixing can lead to tough biscuits, so just combine until everything is mixed nicely.
-
Cool Onions: After caramelizing, let the onions cool completely in the fridge before adding them to the dough. This prevents the butter from melting and keeps your biscuits fluffy.
-
Use Fresh Baking Powder: Check that your baking powder is fresh for the best rise. Old baking powder can lead to dense biscuits.
-
Experiment with Herbs: Feel free to add other fresh herbs like rosemary or thyme for a unique flavor twist in your Caramelized Onion Sourdough Biscuits!
How to Store and Freeze Caramelized Onion Sourdough Biscuits
Room Temperature: Keep the biscuits in an airtight container for up to 2-3 days to maintain freshness and prevent them from drying out.
Fridge: For longer storage, you can refrigerate them in a sealed container for up to a week. Reheat in the oven for a few minutes to restore warmth and texture.
Freezer: Freeze the biscuits individually wrapped in plastic wrap and then placed in a freezer-safe bag for up to 3 months. Reheat directly from frozen at 350°F (175°C) for about 15 minutes.
Reheating: To enjoy the best texture, reheat in the oven to bring back their flaky quality. Avoid microwaving as it can make them chewy.
Make Ahead Options
These Caramelized Onion Sourdough Biscuits are perfect for meal prep enthusiasts!

When you’re ready to serve, combine the components, shape the biscuits, and bake them fresh for a delightful, flaky treat that’s just as delicious as if made on the spot. This thoughtful prep saves you time on busy mornings!
Caramelized Onion Sourdough Biscuits Recipe FAQs
What type of onions should I use for caramelizing?
For the best results, I recommend using yellow onions as they become sweet and flavorful when caramelized. If you prefer a milder taste, shallots are a great alternative.
How should I store leftover biscuits?
Store the Caramelized Onion Sourdough Biscuits in an airtight container at room temperature for 2-3 days. If they are still fresh after that, refrigerate them in a sealed container and enjoy them within a week.

What should I do if my dough is too sticky?
If you find that your biscuit dough is overly sticky, don’t worry! Simply sprinkle a small amount of flour on your work surface and your hands while shaping the dough.
