Step 1: Cook the Pasta and Broccoli. Boil the pasta in salted water according to the package instructions. In the last 5 minutes of cooking, add the broccoli florets to the pot. Drain and set aside.
Step 2: Cook the Chicken. Season the chicken breast with garlic granules, Italian herbs, and onion granules. Heat a frying pan with a spray of oil and cook the chicken until it has some color and is cooked through. Remove from the pan and set aside.
Step 3: Make the Sauce. In the same pan, add a little more oil if needed and fry the diced onion and crushed garlic until softened. Add a splash of the reserved pasta water, then stir in the Elmlea cream, Philadelphia, and Parmesan. Mix well until the sauce is smooth. Add the sundried tomatoes and bring the sauce to a gentle simmer.
Step 4: Combine Everything. Add the cooked pasta, broccoli, chicken, and spinach to the sauce. Stir everything together until evenly coated. Transfer the mixture to a baking dish.
Step 5: Add the Topping and Bake. Sprinkle the grated cheddar evenly over the top of the pasta. Bake in a preheated oven at 180°C (350°F) for 10 minutes, or until the cheese is melted and golden.
Step 6: Serve. Let the pasta bake cool slightly before serving. Enjoy it warm with your favorite side dish!
