Ingredients

  • One large onion: sliced into thick rings provides a sturdy base to hold the cheese without falling apart
  • Mozzarella cheese sticks: offer the perfect melt and stretch making every bite rich and creamy
  • Whole milk: adds moisture to the batter helping it cling nicely to the rings
  • A large beaten egg: acts as a binder for the batter to create a smooth coating
  • Panko breadcrumbs: give the exterior an extra crunchy finish that stays crisp after frying
  • Cooking oil: with a high smoke point is essential for frying to achieve that perfect golden color
  • Toothpicks: hold the layered onion rings together and keep the cheese securely inside during frying
  • All-purpose flour: mixed with baking powder and fine salt creates the initial dry dredge for a light crisp crust

These onion rings are best eaten fresh but can be kept in the refrigerator for up to a day and reheated in the oven to regain crispness avoid microwaving as it softens the coating

Ingredient Substitutions

For a dairy-free alternative use vegan mozzarella and plant-based milk with an egg replacer such as flax egg though texture will vary slightly Gluten-free flour and breadcrumbs can replace regular all-purpose and panko to accommodate gluten intolerance
