Ingredients

For the turkey

  • 2 bone-in (skin-on turkey thighs (about 1 lb total))
  • 3 tbsp butter (softened)
  • 1 tbsp olive oil
  • 1 tsp garlic powder
  • 1 tsp fresh thyme leaves
  • ½ tsp rosemary (minced)
  • ½ tsp sage (minced)
  • Salt and black pepper to taste

For the cauliflower mash

  • 1 medium head cauliflower (cut into florets)
  • 2 tbsp butter
  • 2 tbsp cream cheese
  • 2 tbsp heavy cream
  • 1 garlic clove (roasted or sautéed)
  • Salt and pepper to taste

For the creamy gravy

  • 2 tbsp turkey drippings (or butter if none)
  • ½ cup chicken or turkey broth
  • 2 tbsp heavy cream
  • ½ tsp xanthan gum or 1 tsp arrowroot powder (optional for thickening)
  • Salt and pepper to taste

Instructions 

  • Preheat the oven: Set to 400°F. Pat turkey thighs dry and season with salt and pepper.
  • Make herb butter: In a bowl, mix softened butter, olive oil, garlic powder, thyme, rosemary, and sage.
  • Prep the turkey: Loosen the skin and rub half the butter mixture under it. Rub the rest on top of the skin.
  • Roast: Place on a baking sheet and roast 40–50 minutes, until golden and internal temperature hits 165°F.
  • Start the mash: While turkey cooks, steam or boil cauliflower until tender (about 10 minutes). Drain well.
  • Blend: Add cauliflower, butter, cream cheese, heavy cream, garlic, salt, and pepper to a food processor. Blend until smooth and creamy.
  • Make the gravy: Once the turkey is done, remove it and pour drippings into a pan. Add broth and cream, whisk over medium heat. Sprinkle xanthan gum if using and whisk until thickened. Season to taste.
  • Serve: Plate creamy cauliflower mash, top with sliced turkey, and drizzle generous amounts of gravy.
