Ingredients for Chicken and Broccoli Cheesy Casserole
Main Ingredients:
- 1.5 lbs shredded chicken (rotisserie or cooked and shredded chicken breast)
- 1 lb broccoli, cut into florets
For the Cheese Sauce:
- ¾ cup heavy cream
- 8 oz cream cheese, softened
- ½ cup unsweetened almond milk (adds creaminess without extra carbs)
- 1 tbsp Dijon mustard (adds tangy depth of flavor)
- ¼ tsp ground black pepper
- 1 tsp garlic powder
- ½ tsp salt
For Topping:
- 1 cup shredded cheddar cheese
- ¼ cup fresh basil, chopped (optional, for extra flavor)
Step-by-Step Instructions
Step 1: Prep the Oven & Broccoli
- Preheat the oven to 390°F (200°C).
- Heat a large saucepan with water over high heat.
- Add the broccoli florets and boil for 3-5 minutes, or until tender.
- Drain very well and set aside.
💡 Pro Tip: Overcooked broccoli can become mushy in the casserole, so keep it slightly firm!
Step 2: Combine the Chicken & Broccoli
- In a large mixing bowl, add the shredded chicken and drained broccoli florets.
- Set aside while you prepare the cheese sauce.
💡 Pro Tip: Use rotisserie chicken to save time, or make shredded chicken in the Instant Pot!
Step 3: Make the Cheese Sauce
- In the same saucepan, reduce the heat to low.
- Add the heavy cream, cream cheese, Dijon mustard, garlic powder, almond milk, salt, and pepper.
- Whisk continuously until the cream cheese melts and the sauce becomes smooth.
💡 Pro Tip: Stir frequently to prevent the sauce from burning or clumping!
Step 4: Assemble the Casserole
- Pour the warm cheese sauce over the chicken and broccoli in the bowl.
- Add the chopped basil and mix everything together until well combined.
- Transfer the mixture to a 9×13-inch casserole dish.
Step 5: Add the Cheese & Bake
- Sprinkle 1 cup of shredded cheddar cheese evenly over the casserole.
- Place the dish in the preheated oven and bake for 20-30 minutes, or until the cheese is melted and the casserole is heated through.
- Optional: Broil for 1-2 minutes to make the cheese golden and bubbly.
Step 6: Serve & Enjoy!
- Let the casserole cool for 5-10 minutes before serving.
- Serve warm and enjoy this cheesy, comforting meal!
💡 Pro Tip: This dish tastes even better the next day as the flavors meld together!
