- Shredded Cheese (2 cups): A blend of mozzarella and Parmesan is ideal, but you can use your favorite cheeses.
- Mayonnaise (1/2 cup): Adds creaminess and helps bind the dish together.
- Garlic Powder (1 teaspoon): For a subtle, savory flavor.

How to Make Tennessee Onions
Here’s a step-by-step guide to making this delicious Southern side dish:
Step 1: Preheat the Oven
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or non-stick spray.
Step 2: Prepare the Onions
- Peel the onions and slice them into thick rings, about 1/4 to 1/2 inch thick. Separate the rings and discard the small inner pieces.
Step 3: Layer the Onions
- Arrange the onion rings in a single layer in the prepared baking dish. Overlap them slightly if needed to fit.
Step 4: Make the Cheese Mixture
- In a medium bowl, combine the shredded cheese, mayonnaise, garlic powder, salt, and pepper. Mix until well combined.
Step 5: Assemble the Casserole
- Pour the melted butter evenly over the onion rings. Spread the cheese mixture on top, covering the onions as evenly as possible.
Step 6: Add Optional Toppings
- If desired, sprinkle crushed Ritz crackers or bacon crumbles over the cheese layer for added texture and flavor.
Step 7: Bake
- Bake the casserole in the preheated oven for 30-35 minutes, or until the cheese is melted and bubbly and the onions are tender.
Step 8: Garnish and Serve
- Remove the casserole from the oven and let it cool for a few minutes. Garnish with fresh herbs, if desired, and serve warm.
Variations of Tennessee Onions
While the classic recipe is a hit, there are plenty of ways to customize Tennessee Onions to suit your taste:
- Add Bacon: Sprinkle cooked, crumbled bacon over the cheese layer for a smoky, savory twist.
- Use Different Cheeses: Experiment with different cheese combinations, such as cheddar, Gruyere, or Monterey Jack.
- Make It Spicy: Add a pinch of red pepper flakes or diced jalapeños for a spicy kick.
- Add Vegetables: Mix in sliced bell peppers, mushrooms, or zucchini for added texture and flavor.
- Low-Carb Option: Skip the cracker topping to make the dish keto-friendly.
