How to Make Tennessee Cheesy Onions
1. Preheat the Oven
Set your oven to 350°F (175°C). Lightly grease a baking dish.
2. Soften the Onions
Place sliced onions in a skillet with melted butter and sauté over medium heat for 5–7 minutes, just until slightly softened. Do not brown—they should stay sweet and tender.
3. Mix the Creamy Base
In a bowl, combine mayonnaise, sour cream, half of the shredded cheese, salt, pepper, and any optional seasonings.
4. Assemble the Dish
Spread the onions evenly in the prepared baking dish. Pour the creamy mixture over the top and gently stir to coat. Sprinkle the remaining cheese evenly over everything.
5. Bake Until Bubbly
Bake uncovered for 30–35 minutes, or until the cheese is melted, golden, and bubbling around the edges.
6. Rest and Serve
Let the dish rest for about 5 minutes before serving. This allows the sauce to thicken slightly and makes serving easier.
