Ingredients

2 lbs boneless chicken breasts (about 3 large breasts), cut into cubes
5 medium sweet potatoes, cut into small cubes (skin on or off)
2 heads broccoli, cut into small florets
1 cup buffalo sauce (such as New Primal or Frank’s)
1/2 cup avocado oil or olive oil
1/2 tsp salt
1 tsp pepper
2 tsp garlic powder
1 cup shredded cheddar cheese
1/4 cup chopped green onion
Drizzle of ranch dressing (optional)

Instructions

Step 1: Preheat your oven to 425°F and grease a 9×13-inch casserole dish.
Step 2: Prepare the chicken, sweet potatoes, and broccoli by cutting them into small, bite-sized pieces.
Step 3: In a small bowl, mix together the buffalo sauce, avocado or olive oil, salt, pepper, and garlic powder.
Step 4: Place the sweet potatoes in a large bowl and add half of the buffalo sauce mixture. Toss until the potatoes are well coated.
Step 5: Spread the coated sweet potatoes evenly in the prepared casserole dish. Roast in the oven for 30 minutes, flipping halfway through cooking.
Step 6: While the sweet potatoes roast, add the chicken and broccoli to the bowl the sweet potatoes were in. Pour in the remaining buffalo sauce and toss until everything is fully coated.
Step 7: After 30 minutes, remove the casserole dish and add the chicken and broccoli mixture evenly on top of the roasted sweet potatoes.
Step 8: Return the casserole to the oven and bake for 20–25 minutes, or until the chicken reaches an internal temperature of 165°F.
Step 9: Take the dish out of the oven. Sprinkle shredded cheddar cheese and chopped green onions over the top. Place back in the oven for 5 more minutes, until the cheese melts.
Step 10: Let the casserole cool for a few minutes before serving. Add a drizzle of ranch or blue cheese dressing if desired.

Tips & Variations

For extra heat, add a pinch of cayenne pepper to the buffalo sauce mixture.
Substitute chicken thighs for a juicier texture.
Use sweet potato fries if short on time; just roast longer with the chicken and broccoli.
Try swapping broccoli for cauliflower or green beans if preferred.
For a dairy-free version, omit the cheese or use a plant-based alternative.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave until warmed through, adding a little water if needed to keep the sweet potatoes moist.

How to Serve

Four white bowls filled with a dish are arranged on a white marbled surface. Each bowl has a base layer of roasted orange sweet potato cubes and green broccoli florets that have a little char. On top, there are chunks of cooked chicken with a light golden color and crispy bacon pieces. The dish is garnished with small bits of white cheese crumbles and bright green chopped scallions scattered around. Smooth white sauce is drizzled over the top in uneven thin lines, adding a creamy touch. To the right of the bowls, there is a small white bowl filled with chopped scallions and a white pitcher with extra sauce on a matching white saucer. Photo taken with an iphone --ar 4:5 --v 7
