Understanding the Magic: Onion + Mozzarella

The beauty of this recipe lies in contrast:

Onions become sweet and tender when baked

Mozzarella melts into creamy, stretchy perfection

Breadcrumb coating crisps up beautifully in the oven

The trick is sealing the cheese between two onion rings—creating a pocket that keeps the mozzarella inside while it melts.

Ingredients Overview

For the Onion Rings

2 large sweet onions (Vidalia or yellow)

8 oz mozzarella cheese (block, sliced)

1 cup all-purpose flour

2 large eggs

2 tablespoons milk

1½ cups seasoned breadcrumbs (panko recommended)

½ teaspoon salt

½ teaspoon black pepper

½ teaspoon garlic powder

½ teaspoon paprika

Olive oil spray or brush

Optional Add-Ins

Italian seasoning

Grated Parmesan cheese

Red pepper flakes

Choosing the Right Ingredients

Onions

Sweet onions are best because they soften and caramelize slightly in the oven, balancing the saltiness of the cheese.

Cut onions into thick rings—about ½ inch thick—for stability.

Mozzarella

Use low-moisture, block mozzarella, not fresh mozzarella. Fresh mozzarella releases too much water and can cause sogginess.

Slice mozzarella into thin rounds that fit snugly between onion rings.

Breadcrumbs

Panko breadcrumbs provide the crispiest texture. Seasoned breadcrumbs work too, but panko gives superior crunch.

Step-by-Step Instructions

Step 1: Prepare the Onions

Peel the onions

Slice into thick rings

Separate rings carefully

Pair similar-sized rings together (one slightly larger, one slightly smaller)

Step 2: Assemble the Cheese-Stuffed Rings

Place a slice of mozzarella inside a larger onion ring

Top with a smaller onion ring to “sandwich” the cheese

Press gently to secure

Repeat until all rings are assembled.

Step 3: Set Up the Breading Station

Prepare three shallow bowls:

Bowl 1: Flour

Bowl 2: Eggs + milk, whisked

Bowl 3: Breadcrumbs mixed with salt, pepper, garlic powder, and paprika

This classic breading process ensures even coating and maximum crunch.

Step 4: Bread the Onion Rings

For each stuffed ring:

Dredge in flour (shake off excess)

Dip into egg mixture

Coat thoroughly in breadcrumbs, pressing gently

For extra crispiness, repeat the egg and breadcrumb step a second time.

Step 5: Bake to Crispy Perfection

Preheat oven to 425°F (220°C)

Line a baking sheet with parchment or a wire rack

Arrange rings in a single layer

Lightly spray or brush with olive oil

Bake for 15–18 minutes

Flip and bake another 10–12 minutes

They’re done when golden brown and crisp.

Pro Tips for Perfect Results

✔ Freeze breaded rings for 15 minutes before baking
