Kitchen Tools You’ll Need
Before starting, gather these tools to streamline your cooking process:
- Sharp knife or mandoline
- Mixing bowls (at least 3)
- Deep fryer or heavy-bottomed skillet
- Tongs or slotted spoon
- Cooling rack or paper towel-lined tray
- Small saucepan (for garlic butter)
Having the right tools on hand ensures efficiency and minimizes kitchen mess.
Step-by-Step Instructions for Perfect Mozzarella-Stuffed Onion Rings
Step 1: Slice the Onions and Form Rings
- Peel and slice onions into thick, uniform ½-inch rounds.
- Separate the rings carefully, keeping pairs that nest snugly inside each other.
- Use the larger outer rings as your base and match them with a smaller inner ring to create a space for cheese.
Tips:
- Select onions with wide diameters.
- Avoid using the smallest rings; save those for soups or salads.
Step 2: Add the Mozzarella Cheese
- Cut mozzarella into strips slightly thicker than the ring width.
- Fit cheese between each onion ring pair to form a filled circle.
- Ensure the mozzarella doesn’t poke out; trim as needed.
- Once assembled, place the rings on a tray lined with parchment paper and freeze for 30 minutes.
Benefits of freezing:
- Prevents cheese from leaking during frying
- Helps onion rings keep their shape
Step 3: Set Up Your Breading Station
You’ll need three shallow bowls to create your breading system:
- Bowl 1 (Flour): Add flour, salt, and pepper.
- Bowl 2 (Egg Wash): Beat the eggs until smooth.
- Bowl 3 (Breadcrumbs): Combine panko, Italian breadcrumbs, paprika, and garlic powder.
Tips for success:
- Use one hand for dry ingredients and the other for wet to avoid sticky fingers.
- For extra crunch, double-dip the rings by repeating the egg and breadcrumb steps.
Step 4: Bread the Stuffed Onion Rings
- Dredge frozen onion rings in flour first.
- Dip into egg wash, coating completely.
- Roll in the breadcrumb mixture until fully covered.
- Repeat egg and breadcrumb steps for extra crispiness.
- Return to freezer for another 10–15 minutes.
Double freezing trick:
- Locks in the cheese
- Ensures an ultra-crispy coating when fried
Step 5: Fry to Golden Perfection
- Heat oil in a fryer or heavy pan to 350°F (175°C).
- Test oil with a small breadcrumb—if it sizzles, you’re ready.
- Fry onion rings in batches to avoid overcrowding.
- Cook each ring for 2–3 minutes per side or until golden brown.
- Remove using tongs or a slotted spoon and drain on a paper towel-lined tray or rack.
Important frying tips:
- Maintain oil temperature between 340°F–360°F.
- Overcrowding drops oil temp and results in soggy rings.
Step 6: Prepare the Garlic Butter Sauce
- Melt butter in a small saucepan over low heat.
- Add minced garlic and cook for 1–2 minutes until fragrant.
- Stir in chopped parsley and a pinch of salt.
- Remove from heat and set aside.
Optional twist:
- Add red chili flakes for a spicy kick
- Squeeze in a bit of lemon juice for brightness
Step 7: Serve and Enjoy
- While still hot, brush or drizzle the garlic butter over the onion rings.
- Serve on a platter with dipping sauces like marinara, ranch, or sriracha mayo.
- Garnish with extra parsley for presentation.
These are best enjoyed immediately while still warm and crispy.
