Ingredients (with Pro Insights)
- 2 large sweet onions (Vidalia or yellow onion preferred)
Sweeter onions balance the saltiness of cheese. - 200 g low-moisture mozzarella cheese, cut into sticks
Low-moisture prevents sogginess; freeze slightly before use to avoid leakage. - 1 cup all-purpose flour
Helps the coating stick. Swap with chickpea flour for a gluten-free option. - 2 large eggs (lightly beaten)
Acts as a binder. For vegan versions, use flax eggs. - 1 ½ cups panko breadcrumbs
Provides maximum crunch. Use gluten-free panko if needed. - ½ cup grated Parmesan cheese (optional)
Boosts umami flavor and crispiness. - 1 tsp garlic powder
- 1 tsp smoked paprika
- Salt and black pepper to taste
- Cooking spray or a light drizzle of olive oil
Step-by-Step Instructions
Step 1: Prepare the Onions
- Peel onions and slice into thick ½-inch rings.
- Separate rings and pair similar sizes to create “sandwiches” for mozzarella.
Step 2: Stuff with Mozzarella
- Place a mozzarella stick inside one onion ring.
- Cover with another ring of similar size, creating a sealed “onion-cheese sandwich.”
- Repeat until all rings are stuffed.
Step 3: Dredge and Coat
- Dip stuffed rings in flour (shake off excess).
- Transfer to egg wash.
- Roll in panko + Parmesan + spices mixture.
- For extra crispiness, repeat egg + panko coating once more.
Step 4: Bake to Perfection
- Preheat oven to 425°F (220°C).
- Line a baking sheet with parchment paper.
- Arrange onion rings in a single layer, spray lightly with cooking oil.
- Bake for 18–20 minutes, flipping halfway for even crispiness.
Step 5: Serve Hot
- Let rest for 2 minutes (cheese sets slightly).
- Serve immediately with dipping sauces.
Chef’s Pro Tips
- Freeze mozzarella sticks for 10 minutes before stuffing to prevent leaks.
- Double-coat the onion rings for maximum crunch.
- Use an air fryer at 390°F (200°C) for 12–14 minutes as a faster, oil-free method.
- Don’t overcrowd the baking sheet—this ensures proper airflow for crispiness.

Frequently Asked Questions (FAQs)
Q1: Can I deep-fry instead of baking?
Yes, fry at 350°F (175°C) until golden brown (about 2–3 minutes). Baking is lighter but frying gives extra indulgence.
Q2: Can I use fresh mozzarella?
Not recommended—its high moisture content makes rings soggy. Stick to low-moisture mozzarella.
Q3: How do I prevent cheese from oozing out?
Freeze mozzarella slightly and double-coat with breadcrumbs for a tight seal.
Q4: Can I use red onions?
Yes, they add a sharper flavor, but sweet onions are more balanced.
Q5: Can I make them ahead?
Yes, coat the stuffed onion rings, freeze, and bake directly from frozen (add 5 minutes to baking time).
