Just a handful of simple ingredients—juicy chicken, crisp broccoli, pasta, and plenty of melty cheese—come together for the ultimate cozy meal. Find ingredient notes (including substitutions and variations) below.
👉 Substitutions and Variations
Substitutions:
- Butter: Use olive oil or margarine if preferred.
- Flour: Swap with cornstarch or gluten-free flour for a gluten-free option.
- Whole milk & half and half: Use all whole milk, heavy cream, or a dairy-free alternative like oat or almond milk.
- Chicken broth: Vegetable broth works well, or just use water with a bouillon cube.
- Dijon mustard: Yellow mustard or a pinch of dry mustard powder can stand in.
- Garlic powder & onion powder: Fresh garlic and onion can be sautéed in the butter for added depth.
- Elbow pasta: Any short pasta like shells, rotini, or penne works great.
- Fresh broccoli: Substitute with frozen broccoli, cauliflower, peas, or spinach.
- Rotisserie chicken: Use leftover grilled, baked, or even canned chicken.
- Cheddar cheese: Swap with Gruyère, Colby Jack, or Monterey Jack.
- Yellow American cheese: Use Velveeta, provolone, or more cheddar for a different flavor.
Variations:
- Spicy Kick: Add red pepper flakes, hot sauce, or jalapeños.
- Extra Veggies: Stir in mushrooms, bell peppers, or zucchini.
- Crunchy Topping: Top with breadcrumbs or crushed crackers before baking.
- Lighter Version: Use whole wheat pasta and reduced-fat cheese.
- Indulgent Bake: Transfer to a casserole dish, sprinkle with extra cheese, and bake until bubbly and golden.
😋 Tips & Tricks for the Best Creamy Mac and Cheese with Chicken and Broccoli
- Shred your own cheese: Pre-shredded cheese often has anti-caking agents that prevent smooth melting—freshly grated melts creamier.
- Cook pasta al dente: Slightly undercook the pasta so it holds its shape once mixed with the sauce.
- Steam broccoli lightly: Keep broccoli bright green and slightly crisp—it will finish cooking in the hot sauce.
- Add broth gradually: Pour in broth slowly while whisking to prevent a thin or watery sauce.
- Season in layers: Taste the sauce before adding pasta and adjust salt, pepper, or mustard for balance.
- Serve right away: Creamy mac and cheese is best fresh; if reheating, add a splash of milk to loosen the sauce.
Expert Tip
For the creamiest sauce, whisk the milk and half-and-half slowly into the roux, then stir in cheese off the heat—this keeps it from separating and ensures a smooth, velvety finish.
