Mozzarella-Stuffed Onion Rings with Garlic Butter are the ultimate combination of crispy, savory, and cheesy goodness. These onion rings are taken to the next level by stuffing them with gooey mozzarella cheese, then deep-frying them to golden perfection. Once they’re crispy and hot, they are generously drizzled with a flavorful garlic butter sauce, adding a rich, buttery finish that makes each bite irresistible. Perfect for serving at parties, as an appetizer, or just as a fun snack, these mozzarella-stuffed onion rings are a guaranteed crowd-pleaser.
The contrast between the crunchy, lightly seasoned onion rings and the melty, stretchy mozzarella inside is pure magic. The garlic butter takes it over the top, giving it that extra layer of flavor that makes this dish so special.
🧀 Ingredients:
For the Onion Rings:
- 2 large yellow onions (or sweet onions), peeled and cut into 1-inch thick rings
- 8 oz fresh mozzarella cheese, cut into small sticks (about 2-inch long pieces)
- 1 cup all-purpose flour
- 1 teaspoon paprika
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- ½ teaspoon salt
- ½ teaspoon freshly ground black pepper
- 2 large eggs
- 1 cup breadcrumbs (preferably panko for extra crunch)
- 1 cup buttermilk (or regular milk)
- Vegetable oil, for frying (about 2 cups, or enough for deep-frying)
For the Garlic Butter:
- 4 tablespoons unsalted butter
- 3 cloves garlic, minced
- 1 tablespoon fresh parsley, chopped (optional, for garnish)
- Salt, to taste
- Freshly ground black pepper, to taste
👨🍳 Instructions:
1. Prepare the Onion Rings:
Start by peeling the onions and slicing them into 1-inch thick rings. Carefully separate the rings, and set the smaller ones aside (you’ll just be using the larger rings for stuffing). Discard any loose or broken rings.
2. Stuff the Onion Rings:
Take each of the larger onion rings and stuff them with the mozzarella cheese sticks. You can use the inner rings to “sandwich” the cheese inside. Make sure the cheese is well-hidden inside each ring, and gently press the onion around it so it stays in place.
3. Set Up the Breading Station:
In one shallow bowl, combine the flour, paprika, garlic powder, onion powder, salt, and black pepper. In a second shallow bowl, whisk the eggs and buttermilk together until smooth. In a third bowl, place the breadcrumbs.
4. Bread the Onion Rings:
Dredge each mozzarella-stuffed onion ring first in the seasoned flour, making sure it’s well coated. Then dip it in the egg mixture, letting any excess drip off, and finally coat it in the breadcrumbs. Press gently to make sure the breadcrumbs adhere well. Repeat with all the onion rings.
5. Heat the Oil:
In a large, deep skillet or Dutch oven, heat vegetable oil over medium-high heat. You’ll want enough oil to fully submerge the onion rings, about 2 inches of oil. The oil is ready when it reaches 350°F (175°C). If you don’t have a thermometer, you can test the oil by dropping a small amount of breadcrumbs in—if they sizzle immediately, the oil is ready.
6. Fry the Onion Rings:
Carefully place the breaded onion rings into the hot oil, making sure not to overcrowd the pan. Fry in batches for 2–3 minutes, turning occasionally, until the rings are golden brown and crispy on all sides. Use a slotted spoon to remove the onion rings from the oil and transfer them to a paper towel-lined plate to drain any excess oil.
7. Make the Garlic Butter:
While the onion rings are frying, prepare the garlic butter. In a small saucepan, melt the butter over medium heat. Add the minced garlic and sauté for 1–2 minutes, until fragrant and golden brown. Be careful not to burn the garlic. Once done, remove from heat and season with a pinch of salt and freshly ground black pepper to taste.
8. Serve:
Once all the onion rings are fried, drizzle them with the prepared garlic butter and sprinkle with fresh chopped parsley for a pop of color and freshness. Serve immediately while they’re hot and crispy.
🍴 Serving Suggestions:
- Dipping Sauces: Serve with a variety of dipping sauces such as marinara sauce, ranch dressing, or even a spicy aioli for a flavor-packed experience.
- Pair with a Salad: These mozzarella-stuffed onion rings can be paired with a light salad or coleslaw for a balanced meal.
- For Game Day: Serve these as an appetizer at your next game day party with cold drinks and other finger foods.
🔁 Tips & Variations:
- Mozzarella Substitute: If you want a stronger cheese flavor, try using provolone, cheddar, or a mix of cheeses.
- Baking Option: If you want to reduce the amount of oil used, you can bake these onion rings at 400°F (200°C) for 15–20 minutes or until golden and crispy, flipping halfway through.
- Spicy Kick: Add a pinch of cayenne pepper to the breading mixture or sprinkle some red pepper flakes in the garlic butter for extra heat.
- Air Fryer Version: Preheat your air fryer to 375°F (190°C). Lightly spray the breaded onion rings with cooking spray and air fry in batches for 8–10 minutes, flipping halfway through for even crispness.
