Ingredients

  • 4 cups cooked and Shredded Chicken
  • 2 tbsp olive oil
  • 2 heads broccoli florets removed
  • 10 cremini mushrooms sliced
  • 1/2 small onion diced
  • 1 cup chicken broth
  • 1 recipe Vegan Alfredo Sauce
  • salt and pepper to taste
  • rosemary for garnish

Instructions

  • Make the Vegan Alfredo Sauce and set aside. This can also be made the day before and stored in the fridge.
  • Preheat the oven to 400 degrees fahrenheit.
  • Heat the olive oil in a large sauté pan over medium heat. Add the sliced mushrooms and diced onion and stir for 3 minutes. Add the broccoli florets (make sure they're in bite-sized pieces and not too large) and stir for another 3 minutes or until the broccoli is crisp-tender and bright green.
  • Place the shredded chicken in a 9x13-inch casserole dish, covering the bottom. Add the sautéed mushrooms, onions and broccoli in a flat layer on top.
  • Stir the chicken broth into the Vegan Alfredo sauce, then pour on top of the broccoli in the casserole dish. Use a spatula if needed to make sure everything is well coated.
  • Cook the casserole for 20-25 minutes. The sauce should be bubbling and slightly reduced and thickened. Garnish with fresh rosemary if desired and serve immediately.
