Ingredients List
You only need a few pantry staples and some mozzarella sticks to make these mozzarella-stuffed onion rings with garlic butter:
- 2 large yellow onions, sliced into 1/2-inch rings
- 8 mozzarella sticks, cut to fit the onion rings
- 1 cup all-purpose flour
- 3 large eggs
- 1 cup panko breadcrumbs
- 1/2 cup grated Parmesan cheese
- 1 tsp garlic powder
- 1 tsp dried oregano
- 1 tsp salt
- 1/2 tsp black pepper
- Oil for frying
For the Garlic Butter:
- 4 tbsp unsalted butter
- 2 cloves garlic, finely minced
- 1 tbsp fresh parsley, chopped
- Pinch of salt
Step-by-Step Instructions
1. Build Your Rings
- Separate onion slices into individual rings.
- Pair similar-sized rings and stuff a piece of mozzarella between them.
- Use toothpicks to hold them together if needed, and freeze for 20 minutes. This step helps the cheese stay inside when frying.
2. Bread Them Up
- Set up a dredging station: one bowl of flour, one bowl of beaten eggs, and one bowl of the breadcrumb mix (panko, Parmesan, garlic powder, oregano, salt, pepper).
- Dip each ring in flour, then egg, then breadcrumbs. For extra crunch, dip in egg and breadcrumbs again.
- Chill in the fridge for 10–15 minutes to set the coating.
3. Fry Until Golden
- Heat oil to 350°F (175°C).
- Fry the rings in batches for 2–3 minutes per side until golden and crispy.
- Let them drain on paper towels.
4. Add the Garlic Butter Magic
- In a small pan, melt butter and cook garlic until fragrant. Add a pinch of salt and parsley.
- Drizzle the garlic butter over the hot onion rings right before serving.
Expert Tips
Get the Best Results
- Freeze Before Frying: This locks in the mozzarella and prevents it from oozing out too soon.
- Double Breading: Want an ultra-crispy coating? Do two rounds of egg and breadcrumb.
- Use Panko for Extra Crunch: It makes a big difference in texture.
Avoid These Mistakes
- Don’t skip the freeze step—your cheese might melt right out.
- Make sure the oil is hot enough, or you’ll end up with soggy rings.
- Fry in batches to avoid overcrowding and uneven cooking.
Storage & Reheating
- To Store: Keep leftover mozzarella-stuffed onion rings with garlic butter in an airtight container in the fridge for up to 3 days.
- To Reheat: Use an oven or air fryer at 350°F for 6–8 minutes to get them crispy again. Avoid the microwave—it makes them soggy.
