Whether served as a side dish, holiday casserole, or topping for grilled meats, Tennessee Onions are sure to steal the spotlight at your dinner table.

Ingredients You’ll Need

Before we begin, let’s gather everything for this mouthwatering side:

• 3–4 Sweet Onions (Vidalia recommended) – Mild, sweet flavor perfect for caramelizing.
• 4 Tbsp Butter – Adds richness and helps soften the onions.
• 1 tsp Salt – Enhances natural sweetness of the onions.
• 1 tsp Garlic Powder – Adds savory depth.
• ½ tsp Oregano – For a subtle herbal note.
• 1 cup Italian Blend Cheese – Melty goodness with mozzarella and provolone.
• 1 cup Cheddar Cheese – Sharp, bold flavor.
• ½ cup Parmesan Cheese – For a salty, nutty finish.

Step-by-Step Instructions

1. Prepare the Onions

• Peel your onions and slice into ½-inch thick rings.
• Preheat oven to 375°F (190°C).

2. Sauté with Butter & Seasonings

• In a large skillet, melt the butter over medium heat.
• Add onion rings and cook until translucent and lightly caramelized (about 10–12 minutes).

3. Assemble the Dish

4. Bake to Perfection

• Pair with grilled chicken, steak, pork chops, or even burgers for a side dish that elevates the meal.

Tips for the Best Tennessee Onions

• Choose Vidalia Onions: Their natural sweetness makes this dish shine.
• Keep Cheese Freshly Shredded: Pre-shredded cheese has additives that prevent smooth melting.
• Customize Your Cheese: Try gouda, pepper jack, or Swiss for unique variations.
• Make Ahead: Assemble up to a day in advance and bake just before serving.

• BBQ Companion: Serve with ribs, brisket, or pulled pork.
• Burger Topping: Add a scoop on top of a burger for a gourmet twist.
• Vegetarian Main: Serve with crusty bread and salad for a meatless comfort meal.
