Ingredients
- 1.5 pounds boneless, skinless chicken breasts (or thighs), cut into bite-size pieces
- 4 cups fresh broccoli florets (about 2 medium heads)
- 3 tablespoons butter
- 1 tablespoon olive oil
- 3–4 cloves garlic, minced
- 1 cup heavy cream
- 3/4 cup freshly grated Parmesan cheese (plus extra for serving)
- 1/2 cup chicken broth (low sodium preferred)
- 1/2 teaspoon Italian seasoning (optional)
- 1/4 teaspoon red pepper flakes (optional, for gentle heat)
- Salt and black pepper, to taste
- Fresh parsley, chopped (for garnish, optional)
- Lemon wedge (optional, a quick squeeze to brighten the sauce)
Step-by-Step Instructions
- Prep the broccoli: Cut broccoli into small, even florets. Rinse and pat dry.
This helps them cook quickly and stay crisp-tender.
- Season the chicken: Pat the chicken dry. Season with salt, pepper, and the Italian seasoning, if using. Dry chicken browns better and keeps the sauce from getting watery.
- Sear the chicken: Heat a large skillet over medium-high heat.
Add 1 tablespoon olive oil and 1 tablespoon butter. Add chicken in a single layer and cook 4–6 minutes, stirring once or twice, until golden and cooked through. Transfer to a plate and cover loosely.
- Cook the broccoli: In the same skillet, add another 1 tablespoon butter.
Add broccoli and a pinch of salt. Sauté 2 minutes. Pour in 1/4 cup chicken broth, cover, and steam 2–3 minutes until bright green and crisp-tender.
Transfer broccoli to the plate with chicken.
- Build the Alfredo base: Reduce heat to medium. Add the remaining 1 tablespoon butter and the garlic. Cook 30–60 seconds until fragrant (don’t brown it).
- Make it creamy: Stir in the remaining 1/4 cup chicken broth and heavy cream.
Bring to a gentle simmer. Let it bubble 2–3 minutes, stirring, to slightly thicken.
- Add the cheese: Lower heat to medium-low. Gradually whisk in the Parmesan until melted and smooth.
If the sauce feels too thick, splash in a bit more broth or cream. If too thin, simmer 1–2 more minutes.
- Season: Taste and add salt, pepper, and red pepper flakes if you like heat. A tiny squeeze of lemon brightens everything (optional but recommended).
- Combine: Return the chicken and broccoli to the skillet.
Toss gently to coat and warm through for 1–2 minutes. The sauce should cling to the chicken and veggies.
- Finish and serve: Sprinkle with extra Parmesan and parsley. Serve as is, or over zucchini noodles, spaghetti squash, or cauliflower rice for a heartier plate.
How to Store
- Refrigerate: Cool completely, then store in an airtight container for up to 3–4 days.
- Reheat: Warm gently on the stovetop over low heat or in the microwave at 50% power, stirring occasionally.
Add a splash of cream or broth to loosen the sauce.
- Freeze: Cream sauces can separate after freezing. If you freeze (up to 2 months), thaw overnight and reheat very gently, whisking in a bit of cream to help it come back together.

Common Mistakes to Avoid
- Overcooking the chicken: It turns dry fast. Pull it as soon as it’s no longer pink and let it rest while you make the sauce.
- Boiling the cream hard: High heat can cause the sauce to break.
Keep it at a gentle simmer.
- Using pre-shredded Parmesan: Pre-shredded often has anti-caking agents and doesn’t melt as smoothly. Freshly grated works best.
- Skipping the seasoning: Taste the sauce and adjust salt and pepper. Parmesan is salty, so season gradually.
- Overcooking broccoli: Soft, mushy broccoli waters down the sauce.
Aim for crisp-tender.
Recipe Variations
- Bacon and Mushroom Alfredo: Cook chopped bacon first, remove, then sauté sliced mushrooms in the drippings. Finish the sauce and fold everything together with the chicken and broccoli.
- Cajun Alfredo: Season chicken with Cajun spice instead of Italian seasoning. Add a pinch more red pepper flakes for a kick.
- Spinach and Sun-Dried Tomato: Stir in a couple of handfuls of fresh spinach and a few chopped sun-dried tomatoes when adding the chicken back to the sauce.
- Rotisserie Shortcut: Swap cooked rotisserie chicken for raw.
Start at the broccoli step, then warm the shredded chicken in the sauce.
- “Noodle” Options: Serve over zucchini noodles, shirataki noodles, spaghetti squash, or cauliflower rice to keep it low carb but more filling.
- Dairy Adjustment: For a slightly lighter sauce, replace up to 1/3 of the cream with unsweetened almond milk and simmer a bit longer to thicken.
FAQ
Can I use frozen broccoli?
Yes. Thaw and pat dry first to avoid watering down the sauce. Cook it briefly so it stays firm.
What can I use instead of heavy cream?
You can use half-and-half, but the sauce will be thinner.
Simmer longer to thicken, and add a bit more Parmesan. For the lowest carbs and best texture, heavy cream is ideal.
How do I prevent a grainy sauce?
Keep the heat medium-low when you add Parmesan, and add it gradually while whisking. Avoid boiling after the cheese goes in.
Is this gluten-free?
Yes.
There’s no flour or pasta in this recipe. Just make sure your broth and seasonings are certified gluten-free if needed.
Can I make it ahead?
You can cook the chicken and broccoli and mix the sauce up to a day in advance. Reheat gently with a splash of cream or broth to restore the silky texture.
What protein swaps work well?
Shrimp, turkey, or pork tenderloin slices work great.
If using shrimp, cook it quickly and add at the end to avoid overcooking.
