Tennessee Onions – Better Than Onion Rings

by

Description

Tennessee Onions are a southern classic side dish that take simple sweet onions and transform them into a bubbling, golden, cheesy casserole. Unlike onion rings that are deep-fried, this baked dish layers sweet Vidalia (or other mild) onions with butter, seasonings, and plenty of gooey cheese. The result is a melt-in-your-mouth, savory side that pairs beautifully with grilled meats, barbecue, or even holiday dinners. Crispy on top and tender inside—many say it’s even better than onion rings!

Ingredients for Tennessee Onions – Better Than Onion Rings

  • 3–4 large Vidalia onions (or other sweet onions), thinly sliced into rings

  • ½ cup (1 stick) unsalted butter, melted

  • 1 tsp garlic powder

  • 1 tsp Italian seasoning (or dried thyme/oregano)

  • ½ tsp salt (adjust to taste)

  • ½ tsp black pepper

  • 1 ½ cups shredded sharp cheddar cheese

  • 1 cup shredded mozzarella cheese

  • ½ cup grated Parmesan cheese

  • ½ cup crushed Ritz crackers or panko breadcrumbs (optional for topping)

  • Fresh parsley for garnish (optional)

Instructions

  1. Prep the oven & dish: Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish.

  2. Slice onions: Cut onions into ¼-inch rings and separate them.

  3. Layer onions: Place onion slices evenly in the dish.

  4. Add butter & seasoning: Drizzle melted butter over the onions. Sprinkle with garlic powder, Italian seasoning, salt, and pepper. Toss gently to coat.

  5. Cheese it up: Evenly sprinkle cheddar, mozzarella, and Parmesan cheeses over the onions.

  6. Optional topping: Add crushed Ritz crackers or panko for extra crunch.

  7. Bake: Bake uncovered for 35–40 minutes, until the onions are tender and the top is golden and bubbly.

  8. Serve: Garnish with parsley if desired. Serve warm as a side dish.

Notes

  • Vidalia onions are ideal because of their natural sweetness, but any sweet or yellow onion works.

  • For extra depth, mix in a pinch of smoked paprika or cayenne for spice.

  • This dish reheats well—just cover with foil and bake at 325°F until warmed through.

  • It’s a perfect potluck or holiday side since it feeds a crowd.

Tips

  • Slice onions evenly so they cook at the same rate.

  • Let the dish rest 5 minutes before serving for easier scooping.

  • If you want a creamier version, stir ½ cup sour cream into the onions before baking.

  • For a smoky twist, add crumbled bacon on top before serving.

Servings

  • Serves: 6–8 people as a side dish
