👩🍳 How to Make Sourdough Mozzarella Sticks
-
Prep the cheese: Cut mozzarella sticks in half if you prefer smaller pieces. Place them on a tray and freeze for at least 1 hour — this helps prevent the cheese from oozing out while frying.
-
Set up your breading station:
-
In one bowl: place the flour.
-
In a second bowl: whisk the eggs with milk or water.
-
In a third bowl: mix the breadcrumbs, garlic powder, onion powder, oregano, salt, and pepper.
-
-
Coat the mozzarella:
-
First, roll each frozen cheese stick in flour.
-
Next, dip into the egg wash.
-
Then, roll in the breadcrumb mixture.
-
Finally, dip the stick into the sourdough discard and coat again with breadcrumbs. This double-coating method gives it an ultra-crispy crust.
-
-
Chill (optional but recommended): Place the breaded sticks back in the freezer for 20–30 minutes to help the coating set.
-
Heat the oil: In a deep pan or fryer, heat oil to 350°F (175°C).
-
Fry: Carefully fry the mozzarella sticks in small batches for 1–2 minutes, or until golden brown. Do not overcrowd the pan.
-
Drain and serve: Remove with a slotted spoon and place on a paper towel-lined plate. Serve hot with dipping sauce.
📝 Notes
-
Freezing the sticks before frying is essential to prevent the cheese from melting too fast.
-
Want to bake or air fry? Brush lightly with oil and bake at 400°F (200°C) for 10–12 minutes or air fry for 8–10 minutes.
-
Use panko for extra crunch or gluten-free breadcrumbs if needed.
-
Sourdough discard adds a light tang and helps bind the coating — a great alternative to using just egg or batter.
❓ FAQs
Q: Can I make these ahead of time?
A: Yes! After breading and freezing, store them in a zip-top bag for up to 1 month. Fry directly from frozen when ready to eat.
Q: Can I use fresh sourdough starter instead of discard?
A: Yes, but discard is recommended for a more developed flavor and to avoid interrupting your feeding schedule.
Q: What type of cheese works best?
A: String cheese is ideal because it holds shape and melts well. Avoid fresh mozzarella — it releases too much moisture.
Q: Can I make them dairy-free?
A: Try using dairy-free mozzarella sticks and egg substitutes, though results may vary in texture.
