How This Recipe Can Support Inflammation & Endometriosis

This casserole brings together several ingredients that can be supportive for inflammation-conscious eating:

  • Sweet potatoes are rich in fiber and antioxidants, helping support gut health and stable blood sugar, which are both important when managing inflammation.
  • Broccoli is a cruciferous vegetable that supports natural detox pathways and hormone balance, which can be especially helpful for those navigating endometriosis symptoms.
  • Chicken thighs provide high-quality protein to support muscle repair, satiety, and steady energy throughout the day.
  • Avocado oil offers healthy fats that may help reduce inflammatory responses and support overall hormone health.

While buffalo sauce brings the heat, pairing it with grounding ingredients like sweet potatoes and optional cooling toppings (ranch, avocado, celery) helps create a balanced dish that feels satisfying without being overwhelming.

Ingredients
  

Casserole
  • 3 boneless skinless chicken thighs, cubed
  • 3 medium sweet potatoes peeled and cubed
  • 12 oz broccoli florets bite-size
  • 1 cup buffalo sauce
  • ¼ cup avocado oil
  • 1 tsp salt
  • 1 tsp black pepper
  • 2 tsp garlic powder
  • 1 tsp onion powder
  • 1 cup shredded cheddar cheese
Topping Recommendations (Optional)
  • ranch or blue cheese dressing for drizzling
  • chopped green onions or chives
  • crispy chopped bacon
  • Blue cheese crumbles
  • cilantro
  • diced tomatoes or halved cherry tomatoes
  • shredded carrots
  • chopped Celery
  • avocado

Method
 

  1. Preheat oven to 425°F and lightly grease a 9×13 casserole dish.
  2. Wash and cube the sweet potatoes and chicken. Cut broccoli into bite-size pieces. Season chicken lightly with salt and pepper and set aside (you can refrigerate while prepping everything else).
  3. In a small bowl, whisk together buffalo sauce, avocado oil, salt, pepper, garlic powder, and onion powder.
  4. Add sweet potatoes to the casserole dish. Pour half of the sauce over them and toss until evenly coated.
  5. Bake uncovered for 30 minutes, stirring halfway through for even browning.
  6. Remove dish from oven. Add chicken and broccoli, then pour remaining sauce over everything. Toss gently to combine.
  7. Return to oven and bake for 25 minutes, or until chicken is cooked through and sweet potatoes are fork-tender.
  8. Sprinkle cheddar evenly over the top and bake an additional 3–5 minutes, just until melted.
  9. Drizzle with dressing and add toppings, if desired. Serve warm.

Notes

Cheese: Swap cheddar for pepper jack or mozzarella for a different flavor profile.
Toppings: This casserole is delicious on its own, but toppings take it to the next level. Try drizzling with ranch or blue cheese, then add fresh green onions, chopped bacon, avocado,  or even a sprinkle of blue cheese crumbles. You can keep it a classic buffalo-style with celery and carrots. The possibilities are endless!
Add toppings right before serving for the best texture and flavor.
For meal prep: divide into containers and store in the fridge up to 4 days.
