Ingredients for Tennessee Onions Bake
Main Ingredients
- 3 large sweet or yellow onions
- ½ cup all-purpose flour
- 2 large eggs, beaten
- 1 cup panko breadcrumbs
- ½ cup shredded cheddar cheese
- ¼ cup grated Parmesan cheese
- 1 teaspoon garlic powder
- 1 teaspoon smoked paprika
- Salt and pepper, to taste
- 2 tablespoons olive oil or melted butter
Optional Extras
- ½ teaspoon cayenne pepper for a little heat
- Chopped parsley for garnish
- Ranch dressing or spicy mayo for dipping
How to Make Tennessee Onions Bake
Step 1: Preheat Oven
Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper or lightly grease with cooking spray.
Step 2: Slice the Onions
Peel the onions and slice into ½-inch thick rings. Separate the rings gently. Pat them dry with a paper towel — this helps the coating stick.
Step 3: Prepare the Coating
- Place flour in a shallow bowl.
- Beat the eggs in a separate shallow bowl.
- Mix panko breadcrumbs, cheddar, Parmesan, garlic powder, smoked paprika, salt, and pepper in another bowl.
Step 4: Coat the Onions
- Dredge each onion ring in flour, shaking off excess.
- Dip into beaten eggs.
- Press into breadcrumb-cheese mixture, coating evenly.
Arrange the coated onion rings in a single layer on the prepared baking sheet. Drizzle lightly with olive oil or melted butter for extra crispiness.
Step 5: Bake
Bake for 20–25 minutes, flipping halfway through, until the onions are tender inside and the coating is golden and crispy.
Optional: Broil for 1–2 minutes at the end for extra crunch, watching carefully to prevent burning.
Tips for Perfect Tennessee Onions Bake
- Use sweet onions for natural sweetness and flavor

Make It Healthier
- Use whole wheat or gluten-free panko breadcrumbs
