Ingredients

Here’s what you’ll need to make these mouthwatering Mozzarella-Stuffed Onion Rings with Garlic Butter:

For the Onion Rings:

  • Large onions: The foundation of the dish! Choose onions that are big enough to slice into rings but not so big that they overwhelm the cheese filling.
  • Mozzarella cheese sticks: These are the key to creating the ooey-gooey, melty center.
  • All-purpose flour: For dredging the onion rings before frying, giving them that crispy golden crust.
  • Cornstarch: Helps to create an extra-crunchy coating.
  • Eggs: A little egg wash helps the flour mixture adhere to the onion rings.
  • Panko breadcrumbs: Adds that extra crispiness to the coating. They’re perfect for a satisfying crunch.
  • Salt and pepper: For seasoning the onion rings and the breadcrumb mixture.

For the Garlic Butter:

  • Unsalted butter: The base for our rich garlic butter sauce.
  • Garlic: Fresh garlic is essential for that bold, savory flavor.
  • Fresh parsley: Adds a little pop of color and freshness to the garlic butter.
  • Salt: To bring all the flavors together.

Instructions

Follow these steps to make these irresistible mozzarella-stuffed onion rings:

1. Prep the Onions and Mozzarella

Start by peeling and slicing the onions into thick rings. Try to make each slice around 1/2 inch thick for the best balance of crispy crust and tender onion. Carefully cut the mozzarella sticks into smaller pieces to fit inside the onion rings. You’ll want the mozzarella to be just a bit smaller than the diameter of the onion ring.

2. Stuff the Onion Rings

Place a slice of mozzarella inside each onion ring. Press gently to secure the cheese inside the onion. Set the stuffed onion rings aside on a plate.

3. Prepare the Coating

In one shallow dish, combine flour, cornstarch, salt, and pepper. In another dish, whisk the eggs until smooth. In a third dish, add the panko breadcrumbs.

4. Coat the Onion Rings

Dip each stuffed onion ring into the flour mixture, coating it evenly. Then dip it into the egg wash, and finally, coat it in the panko breadcrumbs. Press gently to make sure the breadcrumbs stick well. Repeat with all the onion rings.

5. Heat the Oil

In a large skillet or deep fryer, heat about 2 inches of vegetable oil over medium-high heat. You can test if the oil is hot enough by dropping a small piece of bread into it—if it sizzles immediately, it’s ready for frying.

6. Fry the Onion Rings

Carefully place the coated onion rings into the hot oil, a few at a time, making sure not to overcrowd the pan. Fry the onion rings for about 3-4 minutes, or until they are golden brown and crispy. Remove them from the oil and place them on a paper towel-lined plate to drain excess oil.

7. Make the Garlic Butter

While the onion rings are frying, melt the unsalted butter in a small saucepan over medium heat. Add the minced garlic and sauté it for about 1-2 minutes, or until fragrant and golden. Stir in the fresh parsley and a pinch of salt. Remove from heat.

8. Drizzle and Serve

Once the onion rings are fried and crispy, drizzle the warm garlic butter over them, making sure each one gets a nice coating. Serve immediately, and enjoy the cheesy, crispy goodness!

How to Serve Mozzarella-Stuffed Onion Rings with Garlic Butter

These mozzarella-stuffed onion rings are perfect on their own as a snack or appetizer, but you can also serve them alongside a variety of dishes:

  • With Dipping Sauces: Serve with marinara, ranch, or spicy mayo for dipping.

  • Pizza Night: These onion rings are the perfect companion to a slice of pizza—cheese and onion rings, what could be better?

Additional Tips

  • Cheese Tip: Use fresh mozzarella sticks for the best stretchiness. Avoid shredded mozzarella, as it won’t melt as nicely.
  • Make Them Ahead: You can prepare the onion rings in advance and freeze them before frying. Just place them on a baking sheet, freeze until solid, then transfer to a bag. Fry them from frozen for a crispy treat.
  • Make It Spicy: If you like a little heat, sprinkle some cayenne pepper into the flour mixture or the breadcrumbs.
  • Try Different Cheeses: You can experiment with different cheese varieties like cheddar, provolone, or pepper jack for a unique twist on the flavor.

Ingredients

Scale


  • For the Onion Rings:


    • 2 large onions, peeled and sliced into 1/2-inch thick rings


    • 8 oz mozzarella cheese, cut into sticks or cubes


    • 1 cup all-purpose flour


    • 1 tsp salt


    • 1/2 tsp black pepper


    • 1 tsp garlic powder


    • 1 tsp paprika


    • 2 large eggs, beaten


    • 1 1/2 cups breadcrumbs (panko or regular)


    • 1/2 cup grated Parmesan cheese


    • Vegetable oil, for frying




  • For the Garlic Butter Sauce:


    • 1/4 cup unsalted butter


    • 3 cloves garlic, minced


    • 1 tbsp fresh parsley, chopped


    • 1/4 tsp red pepper flakes (optional, for heat)


    • Salt, to taste





Instructions

  1. Prepare the onion rings:

    • Cut the onions into 1/2-inch thick rings and separate them carefully. Set aside.

    • Cut the mozzarella cheese into sticks or cubes that are about the size of the onion rings, as these will be stuffed inside.

  2. Stuff the onion rings:

    • Take a few onion rings and stuff each one with a piece of mozzarella cheese. Stack the rings, so you have a filled onion ring with cheese in the center. Repeat until all onion rings are stuffed.

  3. Prepare the breading station:

    • In one shallow bowl, mix the flour, salt, pepper, garlic powder, and paprika.

    • In a second shallow bowl, beat the eggs.

    • In a third shallow bowl, combine the breadcrumbs and Parmesan cheese.

  4. Coat the onion rings:

    • Dredge each stuffed onion ring in the flour mixture, making sure it’s evenly coated.

    • Dip it into the beaten eggs, and then coat it in the breadcrumb mixture, pressing lightly to ensure the breadcrumbs stick.

  5. Fry the onion rings:

    • Heat vegetable oil in a deep pan or fryer to 350°F (175°C).

    • Fry the coated onion rings in batches for 2-3 minutes, or until golden brown and crispy on all sides. Use a slotted spoon to remove them from the oil and place them on a paper towel-lined plate to drain excess oil.

  6. Make the garlic butter sauce:

    • While the onion rings are frying, melt the butter in a small saucepan over medium heat.

    • Add the minced garlic and cook for 1-2 minutes until fragrant, but not browned.

    • Stir in the chopped parsley, red pepper flakes (if using), and salt to taste. Remove from heat.

  7. Serve:

    • Once the onion rings are done, drizzle the garlic butter sauce over the crispy onion rings. Serve immediately, garnished with extra parsley if desired.

Notes

  • Oven-baked option: To make a healthier version, bake the breaded onion rings in a preheated oven at 400°F (200°C) for about 15-20 minutes, flipping halfway through until golden brown.

  • Cheese options: You can substitute mozzarella with other meltable cheeses like cheddar, provolone, or gouda for a different flavor.

 

  • Dipping sauces: Serve these onion rings with a variety of dipping sauces like marinara, ranch, or blue cheese for added flavor.
