Season the chicken: Pat the chicken dry. Season generously with salt, pepper, and the onion powder.
Sear the chicken: Heat the oil in a large skillet over medium-high.
Add chicken in a single layer and cook 5–7 minutes, stirring once or twice, until browned and cooked through. Transfer to a plate.
Steam the broccoli: Add the broccoli to the empty skillet with a splash of water. Cover and steam 2–3 minutes until bright green and crisp-tender.
Remove to the plate with the chicken.
Build the sauce: Lower heat to medium. Add butter to the skillet. When melted, stir in garlic and cook 30 seconds until fragrant.
Add liquids: Pour in the chicken broth and heavy cream.
Stir, scraping up any browned bits. Simmer 3–4 minutes to slightly reduce.
Cheese time: Whisk in the Parmesan a little at a time until smooth and glossy. Add red pepper flakes if using.
Taste and adjust salt and pepper.
Combine: Return chicken and broccoli to the skillet. Toss to coat and warm through for 1–2 minutes. The sauce should cling to everything.
Serve: Garnish with chopped parsley or basil and extra Parmesan.
Serve as-is or over zucchini noodles, shirataki, or spaghetti squash.

Keeping It Fresh

Storage: Refrigerate in an airtight container for up to 4 days.
Reheating: Warm gently on the stove over low heat. Add a splash of cream or broth to loosen the sauce.
Freezing: You can freeze it, but the cream sauce may separate slightly. If you do, thaw overnight and reheat slowly with a bit of cream.
Make-ahead tip: Cook the chicken and broccoli in advance.
Reheat with the sauce right before serving for the best texture.

Health Benefits

Low carb, high satiety: The balance of protein and fat helps keep you full and steady on a keto plan.
Broccoli power: Offers fiber, vitamin C, vitamin K, and antioxidants.
Protein-rich: Chicken supports muscle maintenance and recovery.
No added sugars or starches: The sauce thickens naturally with cream and Parmesan.

What Not to Do

Don’t boil the sauce hard: High heat can cause the cream to split and the cheese to turn grainy.
Don’t skip seasoning: Under-salted sauce tastes flat. Taste as you go.
Don’t overcook the broccoli: Mushy florets water down the sauce and lose their bite.
Don’t use pre-shredded Parmesan if you can help it: Anti-caking agents can make the sauce less smooth.

Alternatives

Protein swaps: Use shrimp, salmon, or rotisserie chicken. For shrimp, cook quickly until pink; for salmon, flake it in at the end.
Dairy adjustments: Replace some cream with mascarpone or cream cheese for extra richness.
For lighter texture, use half cream and half unsweetened almond milk, then reduce longer.
Veggie mix-ins: Add spinach, mushrooms, or asparagus tips. Sauté before making the sauce.
Spice profile: Try lemon zest and black pepper for a bright kick, or Italian seasoning for a herby note.
Serving ideas: Spoon over zucchini noodles, spaghetti squash, or a simple cauliflower mash.

FAQ

How many carbs are in this dish?

Exact carbs vary by brand and portions, but a serving generally lands around 6–8 net carbs without low-carb noodles. Using zucchini noodles adds minimal carbs per serving.

Can I use frozen broccoli?

Yes.

Thaw and pat dry first, or steam briefly and drain well. Excess water can thin the sauce.

How do I prevent a grainy sauce?

Keep the heat moderate, add cheese gradually, and whisk until smooth. Use freshly grated Parmesan for the best melt.

Is there a dairy-free option?

For a non-dairy twist, use full-fat coconut milk and a dairy-free Parmesan alternative.

The flavor will be different but still creamy and satisfying.

Can I make it in advance?

Yes. Cook everything and cool quickly. Reheat gently with a splash of cream or broth before serving to restore the silky texture.

What skillet works best?

A large, heavy skillet (stainless or cast iron) retains heat well and helps brown the chicken nicely without crowding.
