Tennessee Onions (Air Fryer Style) – Better Than Onion Rings

These Tennessee Onions are a Southern comfort classic, made even easier and crispier in the air fryer. Layers of sweet onions smothered in a cheesy, buttery seasoning mix create a side dish or snack that’s bold in flavor, golden on top, and utterly addictive. Think of it as a cheesy, caramelized version of onion rings—without all the deep-frying!

Ingredients

2 large sweet onions (like Vidalia), sliced into ¼-inch rings

2 tbsp unsalted butter, melted

½ tsp garlic powder

½ tsp onion powder

½ tsp Italian seasoning (or dried thyme)

¼ tsp smoked paprika (optional for extra depth)

Salt & pepper to taste

1 cup shredded mozzarella cheese

1 cup shredded sharp cheddar cheese

¼ cup grated Parmesan cheese

Cooking spray or oil mist

Instructions (Step-by-Step)

Prep the Onions (5 minutes)

Peel the onions and slice into ¼-inch thick rounds. Separate the rings gently.

Pat the onion rings dry using a paper towel to help them crisp.

Season and Layer (5 minutes)

In a mixing bowl, toss onion rings with melted butter, garlic powder, onion powder, Italian seasoning, paprika, salt, and pepper.

Spray the bottom of an air fryer-safe baking dish (or use foil/parchment-lined tray) with cooking spray.

Layer half of the onions in the dish. Sprinkle with half the cheddar, mozzarella, and Parmesan.

Repeat with the remaining onions and cheese.

Air Fry (15–18 minutes)

Preheat your air fryer to 375°F (190°C) for 3 minutes.

Place the prepared dish in the air fryer basket.

Cook for 15–18 minutes, or until cheese is bubbly, golden, and onions are soft with crisped edges.

Optional: For extra crisp on top, air fry an additional 2–3 minutes uncovered at 400°F.

Rest and Serve (3–5 minutes)

Let cool slightly to firm up the melted cheese.

Scoop out and serve as a side dish, burger topping, or dip with crusty bread or chips.

Tips & Variations

Spicy kick? Add crushed red pepper or jalapeños.
