1-Start your adventure: by getting your kitchen ready for some fun assembly. Begin with preheating your oven or heating oil, then move on to slicing the onions. This guide walks you through each part to ensure success on the first try.

2-Follow these clear steps: to build and cook the rings: Peel and cut the onions into 1-centimeter (½ inch) rings, then separate the rings. Slice the mozzarella cheese into 4 even strips and place a smaller onion ring inside a larger one, filling the gap with mozzarella strips; for extra cheesiness, use two layers of cheese. Repeat with the remaining onion rings and freeze for 1 hour.

3-Next, set up three separate bowls: one with flour, one with eggs, and one with breadcrumbs. Coat each prepared ring in flour, then dip into the eggs, then breadcrumbs, followed by eggs again, and a final coat of breadcrumbs. Repeat with the remaining rings and return them to the freezer before frying.

4-Heat oil in a large pot: to 350˚F (175°C) and fry the rings until golden brown, taking care not to over-fry to avoid cheese leakage. Drain on paper towels and serve with marinara sauce for the best results. Try pairing with other simple desserts like apple crisp for a full meal.
