Ingredients

4 tbsp butter
2 cups finely chopped onion from 1 large or 2 small
½ tsp kosher salt*
2 cloves garlic, minced
6 tbsp all-purpose flour
4 cups chicken broth
½ tsp freshly-ground pepper
½ cup sour cream
¼ cup mayonnaise
2 cups broccoli florets, cut small from 1 broccoli crown
2 cups cooked brown rice (or any other variety)
2 cups cooked chicken
1 cup grated cheddar
¼ cup breadcrumbs
1 tsp olive oil

Instructions

Preheat oven to 400ºF.
Heat butter in a large cast iron skillet over medium-high heat. Add onions and 1/2 tsp salt and stir. When onions soften (about 6 minutes), add the garlic and cook a minute more.
Sprinkle flour over the onions and stir. Whisk in the broth, 1/2 cup at a time to prevent lumps. Allow mixture to come to a boil and thicken up.
Once the sauce is bubbly and thick, turn off the heat. Whisk in the sour cream, mayo and black pepper. Taste and add more salt to taste (see recipe note below).
Gently stir in the broccoli, chicken and rice. Top with cheese.
Drizzle olive oil over breadcrumbs in a small bowl and use your fingers to combine until all the breadcrumbs are moistened. Sprinkle over cheese. Bake until bubbly and golden, about 20 minutes.

Notes

*If you use salted broth, you probably won't need more salt. If you use unsalted, you'll need about another 1 1/4 tsp kosher salt.
