Creamy, comforting and packed with chicken, broccoli and rice, this one-skillet casserole is the perfect blend of flavour and texture.

Ingredients

  • 1/4 cup butter

  • 2 cups finely chopped onions

  • 1/2 tsp kosher salt

  • 2 tsp minced garlic

  • 6 tbsp all-purpose flour

  • 3 to 4 cups chicken broth, divided

  • 1/2 cup sour cream

  • 1/4 cup mayonnaise

  • 1/2 tsp pepper

  • 2 cups small broccoli florets

  • 2 cups chopped cooked chicken

  • 2 cups cooked brown rice

  • 1 cup grated cheddar cheese

Instructions

  • Position rack in centre of oven, then preheat to 400F.

  • Melt butter in a large oven-safe frying pan over medium-high. Add onions and salt. Cook, stirring often, until softened, about 6 min. Add garlic and cook for 1 min, until fragrant.

  • Sprinkle flour evenly over cooked onions. Stir to coat. Gradually whisk in 3 cups chicken broth, ½ cup at a time, to avoid lumps. Bring to a boil, stirring often, until sauce is thick and bubbly. Add more broth, as needed, if sauce seems too thick.

  • Whisk sour cream and mayo with a spoonful of sauce in a medium bowl until smooth. Then whisk sour cream mixture into sauce in pan. Stir in pepper; taste and add more salt, if desired.

  • Set aside a few broccoli florets. Stir in remaining broccoli, chicken and rice into sauce. Sprinkle cheese and scatter reserved broccoli overtop.

  • Bake until casserole is bubbly and cheese is melted and golden, about 20 min.
