Ingredients

  • Boneless chicken breast: Choose plump firm chicken and slice into even pieces for even cooking
  • Pasta: Penne or a similar short pasta holds the sauce beautifully and makes every bite satisfying
  • Broccoli florets: Use fresh for a little bite or lightly steam to keep the flecks bright green
  • Cajun seasoning: This is where all the bold flavor comes in so check your blend for a good balance of paprika garlic and cayenne
  • Heavy cream and milk: Go with full fat cream for the richest sauce and whole milk for a silkier finish
  • Grated mozzarella or Monterey Jack cheese: Freshly grated cheese melts better and gives a smoother sauce
  • Butter and olive oil: This combo brings both richness and a hint of savory flavor when sautéing chicken
  • Fresh garlic: Gives the sauce real depth make sure to use freshly minced cloves
  • Salt and freshly ground black pepper: Good seasoning makes everything pop so season at every stage

Step-by-Step Instructions

Season the Chicken:
Pat chicken dry and season generously with salt pepper and Cajun seasoning letting it rest for a couple of minutes so the spices start to lock onto the meat
Boil the Pasta and Prepare the Broccoli:
Bring a pot of salted water to a rolling boil and cook pasta just until al dente this gives a tiny bit of bite once baked Later strain and set aside Steam or lightly boil broccoli just until bright and crisp tender drain and set aside
Sauté the Chicken:
Heat butter and olive oil in a wide pan over medium high Add seasoned chicken in a single layer and cook without moving it too much for about five minutes per side until golden and cooked through Remove the chicken to a plate to avoid overcooking
Start the Alfredo Sauce:
In the same skillet reduce heat to medium Add minced garlic and stir constantly for about one minute until you can smell its aroma but avoid letting it brown
Blend in Cream and Milk:
Pour in heavy cream scraping up any browned bits for flavor then add milk slowly stirring to keep the sauce base silky and prevent burning
Add the Cheese:
Once the cream mixture is near simmering scatter in grated cheese and stir slowly letting it melt completely for a thick velvety sauce
Mix Everything Together:
Return cooked pasta chicken and broccoli to the pan Gently toss them in the hot sauce making sure every piece is thoroughly coated Adjust seasoning if needed with more Cajun or salt

I love watching my kids sneak the first bite straight from the pan while the cheese is still stringy This sauce is my unbeatable trick for getting everyone to devour broccoli without a single complaint

Storage Tips

Refrigerate leftovers promptly in an airtight container and they will stay luscious for up to three days If reheating add a spoonful of milk or cream and stir gently over low heat to bring back the creamy texture without curdling Avoid freezing as creamy sauces may separate and lose their silky appeal

Ingredient Substitutions

Swap the chicken for turkey breast or boneless thighs if you want a more robust flavor For a vegetarian twist double up on broccoli and add sautéed mushrooms or bell peppers If you need a lighter sauce you can use half and half in place of heavy cream and part skim mozzarella in place of full fat cheese

Serving Suggestions

Pair this spicy cheesy pasta with a crisp green salad and a slice of warm garlic bread For special occasions finish with a sprinkle of shredded parmesan and fresh parsley You can even toss roasted cherry tomatoes on top for juicy bursts of sweetness

Recipe FAQs

→ Can I use pre-cooked chicken for this dish?

Yes, you can add sliced or shredded pre-cooked chicken when combining the pasta and broccoli. Heat through gently in the sauce.

→ What's the best way to ensure the broccoli stays bright green?

Steam or briefly blanch the broccoli until just tender, then quickly rinse under cold water to set the color before adding it to the dish.

→ How can I make this meal spicier?

Increase Cajun seasoning to your taste, or add a pinch of red pepper flakes for additional heat during sautéing.

→ What other cheeses work well in the sauce?

Monterey Jack, Parmesan, or a blend of mozzarella and sharp cheddar can also give the sauce great flavor and creaminess.

→ Is it possible to substitute the pasta shape?

Absolutely; penne works well, but rotini, fusilli, or fettuccine are all great options for holding onto the creamy sauce.

Ingredients

01 1½ lb chicken breast, cut into bite-sized pieces
02 Salt and freshly ground pepper, to season
03 1 tablespoon butter

06 1 cup heavy cream (35%)

08 1¼ cup grated mozzarella or Monterey Jack cheese
09 1 cup broccoli florets, fresh or lightly steamed
10 1 cup pasta (penne recommended)
11 Cajun seasoning, to taste (approximately 1–2 tsp or more if desired)

Steps

Step 01

Season the chicken pieces with salt, pepper, and Cajun seasoning if using. Let them sit for a couple of minutes to absorb the flavors.

Step 02

Cook pasta al dente according to package directions, then drain. Meanwhile, steam or cook the broccoli until tender but still bright green. Set both aside.

Step 03

In a large pot or skillet, heat the butter and olive oil over medium-high heat. Add the seasoned chicken and sauté for about 5 minutes on each side, or until cooked through. Remove chicken from the pot and set aside.

Step 04

In the same pot, reduce heat to medium. Add garlic and cook until fragrant, about 30 seconds to 1 minute. Pour in heavy cream and gradually add milk while stirring constantly to prevent overheating. Bring the mixture just to a simmer.

Step 05

When the sauce is warm, stir in the grated mozzarella or Monterey Jack cheese until fully melted and the sauce is smooth and well blended.

Step 06

Add the cooked pasta, chicken pieces, and broccoli into the sauce. Stir well to combine everything, ensuring all ingredients are coated. Heat through and adjust seasoning with additional salt, pepper, or Cajun seasoning if needed.

Step 07

Serve immediately while the dish is hot and creamy. Optionally garnish with extra cheese, freshly cracked black pepper, or chopped parsley.
