Prepare Ingredients: Chop chicken into bite-sized pieces and cut broccoli into florets. Grate Parmesan cheese and mince garlic.

Boil Pasta: In a pot, bring salted water to boil, add pasta and cook until nearly al dente. Add broccoli in the last 3 minutes of cooking.

Cook Chicken: Heat olive oil in a skillet. Season chicken with salt and pepper, sauté until golden brown and cooked through, about 5-7 minutes.

Make Sauce: In the same skillet, melt butter, add garlic, and sauté briefly. Add heavy cream and simmer, then stir in Parmesan until smooth.

Combine: Return pasta and broccoli to skillet, add chicken, and gently toss everything with the sauce.

Serve: Dish out into bowls and garnish with parsley or basil. Add more Parmesan if desired.
