What Are Cheesy Baked Tennessee Onions?

Cheesy Baked Tennessee Onions are a southern staple that turns simple ingredients—sweet onions, melted cheese, and buttery crackers—into a decadent dish bursting with rich flavors. This bake relies on the sweetness of Vidalia onions, balanced by the sharpness of cheddar, the meltiness of mozzarella, and the nutty undertones of Parmesan.

While this might sound like an unusual combination, trust us—once you try it, you’ll be hooked. The dish is baked until the cheese is bubbly and golden, and the onions are sweet and tender. A topping of crushed buttery crackers provides the perfect crunch in every bite.

Ingredients Breakdown

Let’s dive into each component of this flavorful dish and understand why it’s essential:

• 3 large sweet onions: Vidalia onions are preferred for their mild, sweet flavor.
• 2 tablespoons melted butter: Adds richness and helps everything caramelize.
• 1/2 teaspoon garlic powder: Enhances flavor without overpowering the onions.
• Salt and black pepper: Basic seasoning to bring everything to life.
• 1 cup shredded cheddar cheese: Sharp and flavorful.
• 1 cup shredded mozzarella cheese: Adds a stretchy, melty texture.
• 1/4 cup grated Parmesan cheese: Brings a salty, nutty punch.
• 1/4 cup crushed Ritz crackers: The crunch factor.
• 1 tablespoon fresh parsley (optional): For a pop of color and freshness.

Step-by-Step Instructions

1. Preheat Oven

Start by preheating your oven to 375°F (190°C). Grease a 9×9-inch baking dish to prevent sticking and to help with even browning.

2. Prep the Onions

Peel and slice the onions into thick rings, about 1/2 inch each. Separate the rings and place them into the greased baking dish.

3. Season & Coat

Drizzle the melted butter over the onions. Sprinkle with garlic powder, salt, and pepper. Toss the rings gently to make sure every slice is well coated.

4. Layer the Cheese

Evenly sprinkle the cheddar, mozzarella, and Parmesan cheeses on top of the onions. Don’t skimp here—the cheese is the star!

5. Add Crunch

Top the cheesy onion layers with crushed Ritz crackers for that golden-brown, crispy finish.

6. Bake

Place the dish in your preheated oven and bake uncovered for 25–30 minutes, or until the onions are tender and the cheese is bubbling and golden.

7. Garnish and Serve

Once out of the oven, let it cool for a few minutes. Garnish with fresh parsley if using, and serve warm.
