• Chopped fresh chives for garnish (optional)

Instructions

Prepare the Casserole:

1. Caramelize the Onions:
   • In a large skillet, melt the butter over medium heat. Add the sliced onions and cook, stirring occasionally, until the onions are soft and golden brown, about 25-30 minutes.
2. Preheat the Oven:
   • Preheat your oven to 350°F (175°C).
3. Assemble the Layers:
   • In a greased baking dish, layer half of the caramelized onions. Top with half of the shredded cheddar cheese and half of the crushed buttery crackers. Repeat the layers.
4. Mix the Creamy Mixture:
   • In a bowl, combine mayonnaise, sour cream, salt, and black pepper. Mix until well blended.
5. Pour the Creamy Mixture:
   • Pour the mayonnaise and sour cream mixture over the layered onions, cheese, and crackers, ensuring it evenly covers the casserole.
6. Finish with Toppings:
   • Sprinkle the remaining shredded cheddar cheese and crushed crackers on top.
7. Bake to Perfection:
   • Bake in the preheated oven for 25-30 minutes or until the casserole is hot and bubbly, and the top is golden brown.
8. Garnish and Serve:
   • Garnish with chopped fresh chives if desired. Allow the casserole to cool for a few minutes before serving.
