Ingredients for Tennessee Onions Bake
Main Ingredients
- 3 large yellow or sweet 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

How to Make Tennessee Onions Bake
Step 1: Preheat Oven and Prepare Pan
Preheat your oven to 400°F. Line a baking sheet with parchment paper or lightly grease with cooking spray.
Step 2: Slice and Prep Onions
Peel onions and cut into ½-inch thick rings. Separate the rings gently.
Pat the onion rings dry with a paper towel — this helps the coating stick better.
Step 3: Prepare Coatings
- Place flour in a shallow bowl.
- Beat eggs in another shallow bowl.
- Mix panko breadcrumbs, cheddar, Parmesan, garlic powder, smoked paprika, salt, and pepper in a third bowl.
Step 4: Coat the Onion Rings
- Dredge each onion ring in flour, shaking off excess.
- Dip into the beaten eggs.
- Press into the breadcrumb-cheese mixture, coating evenly.
Arrange the coated rings on the prepared baking sheet in a single layer. Drizzle with olive oil or melted butter for extra crispiness.
Step 5: Bake Until Golden
Bake at 400°F for 20–25 minutes, flipping halfway through, until the onions are tender inside and the coating is golden and crispy.
For extra crunch, broil for 1–2 minutes at the end — but watch carefully to prevent burning.
Tips for Perfect Tennessee Onions Bake
- Use sweet or yellow onions for natural sweetness
- Pat onions dry before coating to ensure crispy coating
- Don’t overcrowd the baking sheet — air circulation is key for crispiness
- Add smoked paprika or cayenne for a subtle smoky kick
- Serve immediately for the best texture
Make It Healthier
- Use whole wheat panko or gluten-free breadcrumbs
- Swap half the cheese for nutritional yeast
- Use cooking spray instead of drizzling oil
- Serve with a side of roasted vegetables or salad
You’ll still get that irresistible crunch with fewer calories.
Serving Suggestions
- As a side for burgers, sandwiches, or steaks

- Topped with fresh herbs like parsley or chives
- Paired with baked chicken or fish for a complete meal

Storage and Leftovers
Refrigerator

Freezer
Freeze unbaked coated onion rings in a single layer on a tray, then transfer to a freezer bag for up to 2 months. Bake directly from frozen, adding 5 extra minutes to cooking time.
Frequently Asked Questions
Can I use red onions?

Can I make this vegan?
