Ingredients Equipment Method Notes

Ingredients
  

  • 30 oz frozen broccoli florets (do not thaw)
  • 3 cups pre-cooked shredded chicken (rotisserie or leftover)
  • 2 tbsp butter
  • 1/2 onion, chopped
  • 2 tsp minced garlic
  • 1 1/2 cups heavy whipping cream
  • 1 cup unsweetened almond milk
  • 2 cups shredded sharp cheddar cheese
  • 1/4 cup chopped green onions
  • salt and pepper, to taste
  • crushed pork rinds or baked Parmesan (optional topping)

Equipment

  • 6-quart slow cooker
  • saucepan for cream sauce
  • wooden spoon
  • cutting board and knife
  • measuring cups and spoons

Method
 

  1. Add frozen broccoli florets, shredded chicken, and green onions to the slow cooker.
  2. In a saucepan, melt butter over medium heat. Add chopped onion and sauté for 5 minutes until soft. Stir in garlic and cook for 30 seconds until fragrant.
  3. Pour in heavy cream and almond milk. Season with salt and pepper. Simmer gently for 3–5 minutes, stirring constantly, until slightly thickened.
  4. Pour the thickened cream sauce over the chicken and broccoli in the crockpot. Top evenly with shredded cheddar cheese.
  5. Cover and cook on HIGH for 2 hours (or until cheese is melted and bubbly, and broccoli is tender).
  6. Serve hot, topped with optional crushed pork rinds, extra cheese, or chopped green onions.

Notes

Use pre-cooked shredded chicken and frozen broccoli for speed and convenience. Pre-simmering the cream sauce for 3–5 minutes ensures the perfect thick, velvety consistency. Add a crunchy topping of crushed pork rinds or baked Parmesan just before serving for extra texture and flavor.
