This Buffalo chicken & rice casserole recipe is an easy weeknight dinner with just a bit of extra spice.
Preheat oven to 400°. In a medium skillet over medium heat, heat oil. Add onion, carrots, and celery and cook, stirring occasionally, until softened, 7 to 8 minutes. Add garlic and cook, stirring, until fragrant, about 1 minute more. Add garlic powder and onion powder; season with salt and pepper. Add rice and cook, stirring frequently, until slightly toasted, about 2 minutes.
Transfer rice mixture to a 13"-by-9" baking dish. Add cream cheese and stir until combined. Add broth, chicken, and Buffalo sauce and stir again to combine; season with salt and pepper.
Cover dish with foil and bake casserole until rice is tender, 40 to 45 minutes.
Carefully remove foil. Stir casserole, then top with crackers and cheddar. Continue to bake, uncovered, until cheese is melty and crackers are darkened, about 10 minutes. Let cool slightly.
Top with scallions and blue cheese. Serve with sour cream alongside.
