Preheat the oven to 350°F (175°C).
Heat olive oil in a skillet over medium heat. Add chopped onion, celery, and green bell pepper. Sauté for 5 minutes until vegetables are softened.

Add chicken broth to the mixture and stir until evenly combined.

Sprinkle the remaining 1/2 cup shredded cheddar cheese evenly over the top.
Cover the casserole with aluminum foil and bake for 30 minutes.
Remove the foil and bake for an additional 15 minutes, or until the cheese is melted and bubbly.
Let the casserole rest for 5 minutes before serving.
