Crispy Parmesan Onion Chips

These Crispy Parmesan Onion Ring Chips have become one of my favorite snacks to whip up whenever friends come over. The combination of a crunchy, flavorful coating with tender onion inside makes them irresistible and perfect for sharing.

I first made these for a casual game night and everyone kept going back for more. Now they’re a regular request whenever I bring out the fryer.

Ingredients

• Large onions sliced into thin ¼ inch rings: choosing firm, fresh onions ensures flavorful, evenly cooked chips
• Buttermilk: softens onions and improves adhesion of the coating
• All-purpose flour mixed with garlic powder, paprika, salt, and black pepper: this seasoned flour layers flavor and helps create a light crust
• Grated Parmesan cheese blended with seasoned breadcrumbs: the key to that crispy nutty texture and robust taste use freshly grated Parmesan for best results
• Vegetable or canola oil: ideal for frying due to their neutral flavor and high smoke points

Instructions

Begin by slicing the onions into uniform rings about one quarter inch thick:

Carefully cutting even slices ensures they cook at the same rate, preventing some from burning while others stay undercooked.

Pour the buttermilk over the onion rings in a large bowl:

Let them soak for at least 30 minutes. This step softens the onions slightly and helps the flour mixture stick better, which is essential for a crispy coating.

Set up a dredging station by combining the flour with the garlic powder, paprika, salt, and black pepper in one bowl:

Mix thoroughly to distribute the spices evenly throughout the flour.

In a second bowl, mix the grated Parmesan cheese together with the seasoned breadcrumbs:

This mixture forms the flavorful crunchy layer that makes these chips special.

After soaking, remove the onion rings from the buttermilk, allowing any excess liquid to drip back into the bowl:

Too much moisture can prevent the coating from adhering properly.

Dip each ring first into the seasoned flour mixture, coating it well:

Then press the ring gently but firmly into the Parmesan-breadcrumb mixture so the coating clings tightly. Working in batches prevents sogginess and overcrowding.

Heat oil about one to two inches deep in a heavy skillet over medium heat until it reaches roughly 350 degrees Fahrenheit:

Using a thermometer helps maintain the right frying temperature for crispiness without greasiness.

Carefully add the coated onion rings to the hot oil in small batches:

Fry for three to four minutes on each side or until the chips turn golden brown. Turn gently to keep the coating intact and ensure even cooking.

Transfer the fried onion ring chips to a paper towel-lined plate to drain excess oil:

This keeps them crisp rather than greasy.

Serve immediately while hot and crunchy:

These go great with any dipping sauce from classic ketchup to spicy aioli.

Parmesan cheese is my favorite ingredient here because its salty, nutty flavor contrasts beautifully with the sweet onion. I remember making these for a family movie night once and everyone raved about how much better they tasted compared to ordinary onion rings.

Storage Tips

Store leftover chips in a sealed container lined with paper towels to absorb moisture. They keep well for up to two days in the refrigerator. Reheat gently in an oven or air fryer to regain crispness, avoiding microwaves that make them soggy.

Ingredient Substitutions

If you don’t have buttermilk, a mixture of milk and a splash of lemon juice or vinegar works as a substitute to mimic acidity needed for softening. Gluten-free flour and breadcrumbs can be swapped to accommodate dietary needs without sacrificing texture much. Parmesan can be replaced with Pecorino Romano or a sharp aged cheese for a slightly different flavor profile.

Serving Suggestions

These onion ring chips shine as a side to burgers, sandwiches, or grilled meats. They are also fantastic on their own with dips like ranch, spicy mayo, or even a balsamic glaze for a gourmet twist.

These crispy onion ring chips are perfect for any occasion and always impress. Enjoy the process and the delicious results!
