Tennessee Onions - The Cheesy Baked Side Recipe

5 from 7 reviews

Tennessee Onions is a cheesy baked onion side dish that surpasses traditional onion rings by layering sweet onions with a blend of mozzarella, provolone, and Parmesan cheeses, seasoned with Italian herbs and baked to golden bubbly perfection.

Ingredients

Scale

Vegetables

  • 2 large sweet onions (Vidalia or yellow), sliced ½ inch thick

Dairy

  • 4 tablespoons butter, cut into small pats
  • 1 cup shredded mozzarella cheese
  • 6 slices provolone cheese
  • ½ cup grated Parmesan cheese

Seasonings

  • 1 teaspoon Italian seasoning
  • ½ teaspoon salt
  • ¼ teaspoon black pepper

Instructions

  1. Preheat Oven: Preheat your oven to 375°F (190°C) and lightly butter a baking dish to prevent sticking and add extra richness to the dish.
  2. Arrange Onions: Place the sliced onions in a single even layer inside the prepared baking dish to ensure even cooking and uniform cheese coverage.
  3. Season and Butter: Sprinkle the onions evenly with salt, pepper, and Italian seasoning for a balanced flavor profile. Dot the top with the small pats of butter to melt throughout the onions during baking.
  4. Add Cheeses: First, sprinkle the shredded mozzarella cheese over the onions. Next, layer the slices of provolone cheese, and finally top everything off with the grated Parmesan cheese for a rich, melty, and flavorful cheese crust.
  5. Bake: Place the dish in the oven uncovered and bake for 25 to 30 minutes, or until the cheese is golden and bubbling, and the onions are tender.
  6. Optional Broil: For an extra crispy top, broil the dish for 2 minutes, watching carefully to avoid burning.
  7. Rest and Serve: Remove from the oven and let the dish rest for about 5 minutes to allow it to set slightly, making it easier to serve and enhancing the flavors.

Notes

  • Use sweet onions like Vidalia for optimal natural sweetness and milder flavor.
  • Adjust cheese quantities to preference for a lighter or richer casserole.
  • Broiling is optional but enhances crispiness on top.
  • Serve as a side dish with grilled meats or Vegetarian main courses.
  • Make sure to slice the onions evenly to ensure consistent cooking.
  • Leftovers can be refrigerated and gently reheated in the oven.
