Ingredients

For the Chicken and Broccoli:

1.5 lbs. boneless, skinless chicken breasts (cut into bite-sized pieces)
3 cups broccoli florets (fresh or frozen, about 12 oz.)
2 tablespoons olive oil or avocado oil
Salt and black pepper to taste

For the Creamy Garlic Sauce:

4 tablespoons unsalted butter
6 cloves garlic (minced, for maximum aromatic impact)
1 cup heavy cream (full-fat for richest texture)
1 cup chicken broth (low-sodium preferred)
¾ cup freshly grated parmesan cheese (avoid pre-shredded for smoother sauce)
1 teaspoon Italian seasoning
½ teaspoon red pepper flakes (optional, for gentle heat)
2 teaspoons xanthan gum or 1 tablespoon cream cheese (for thickening, optional)

The quality of your garlic and parmesan makes a tremendous difference in this creamy garlic chicken dish, so choose fresh garlic cloves and real parmesan cheese rather than the shelf-stable varieties.

Pro Tips

Low Carb Creamy Garlic Chicken & Broccoli

Achieve Perfectly Tender Chicken: Cut your chicken into uniform, bite-sized pieces to ensure even cooking. Pat the chicken completely dry with paper towels before seasoning and cooking—this crucial step allows the chicken to develop a beautiful golden sear rather than steaming in its own moisture. Avoid overcrowding the pan, which traps steam and prevents proper browning; cook in batches if necessary.

Master the Cream Sauce Consistency: Add your heavy cream at room temperature to prevent breaking or curdling when it hits the hot pan. If your sauce seems too thin, don’t panic—let it simmer gently for a few extra minutes to reduce naturally, or whisk in a small amount of xanthan gum (start with ½ teaspoon) for instant thickening without added carbs. Always add parmesan off the heat or on very low heat while whisking constantly to prevent the cheese from clumping or separating.

Perfect Your Broccoli Texture: Nobody wants mushy broccoli in their low carb creamy chicken and broccoli. Add the florets during the last 5-7 minutes of cooking so they become tender-crisp while absorbing the garlic cream sauce. If using frozen broccoli, there’s no need to thaw—just add an extra minute or two to the cooking time.

Step-by-Step Instructions

Step 1: Prepare Your Ingredients

Begin by cutting the chicken breasts into uniform 1-inch pieces and patting them thoroughly dry with paper towels. Season generously with salt and black pepper on all sides. Cut the broccoli into bite-sized florets, keeping the sizes consistent for even cooking. Mince the garlic cloves finely—this releases more of the aromatic oils that make this dish so irresistible. Having everything prepped before you start cooking ensures smooth execution since the recipe moves quickly once you begin.

Step 2: Sear the Chicken

Heat a large skillet or deep sauté pan over medium-high heat and add the olive oil. Once the oil shimmers, add the chicken pieces in a single layer, working in batches if your pan isn’t large enough to avoid overcrowding. Let the chicken cook undisturbed for 3-4 minutes until a golden-brown crust forms on the bottom. Flip each piece and cook for another 3-4 minutes until the chicken is cooked through with an internal temperature of 165°F. Transfer the chicken to a plate and set aside—don’t worry if it seems slightly underdone as it will finish cooking in the sauce.

Step 3: Build the Aromatic Base

Reduce the heat to medium and add the butter to the same skillet, scraping up any flavorful browned bits from the chicken. Once the butter melts and begins to foam, add the minced garlic and sauté for 60-90 seconds until fragrant and just beginning to turn golden. Watch carefully during this step because garlic can burn quickly, which would make the sauce bitter. The kitchen should smell absolutely amazing at this point.

Step 4: Create the Creamy Sauce

Pour in the chicken broth and use a wooden spoon to scrape up any remaining browned bits stuck to the pan—these add tremendous flavor to your creamy garlic chicken with broccoli. Add the heavy cream, Italian seasoning, and red pepper flakes if using. Bring the mixture to a gentle simmer, stirring occasionally. Let it bubble gently for 3-4 minutes to allow the flavors to meld and the sauce to reduce slightly. The sauce will thicken more once you add the cheese.

Step 5: Add Cheese and Vegetables

Remove the pan from direct heat or reduce to the lowest setting. Gradually whisk in the parmesan cheese, stirring constantly until it melts completely into the sauce and creates a silky texture. Return the cooked chicken to the skillet along with any accumulated juices. Nestle the broccoli florets into the sauce, stirring gently to coat everything evenly. Return to medium-low heat and simmer for 5-7 minutes until the broccoli reaches your desired tenderness and the chicken is heated through.

Step 6: Final Adjustments

Taste the sauce and adjust seasoning with additional salt and black pepper as needed. If the sauce seems too thin for your preference, let it simmer for another 2-3 minutes, or whisk in a small amount of xanthan gum or cream cheese for immediate thickening. The Low Carb Creamy Garlic Chicken & Broccoli should have a luxurious, coating consistency that clings to the chicken and vegetables. Serve immediately while hot and creamy.

Variations

Keto Garlic Parmesan Chicken with Vegetables: Expand beyond broccoli by adding cauliflower florets, sliced mushrooms, or baby spinach for variety. The mushrooms add an earthy depth while spinach wilts beautifully into the cream sauce. You can also substitute chicken thighs for breasts if you prefer darker, more succulent meat with additional fat content.

Dairy-Free Version: Replace the heavy cream with full-fat coconut cream and substitute the parmesan with nutritional yeast for a cheesy flavor without dairy. Use ghee instead of butter or stick with olive oil. The result won’t be identical but still delivers a creamy, satisfying low-carb meal.

Sun-Dried Tomato and Basil: Add ⅓ cup chopped sun-dried tomatoes (oil-packed and drained) and 2 tablespoons fresh basil to the sauce for a Mediterranean twist on this garlic cream chicken recipe. The tomatoes add tangy sweetness while the basil brings freshness that balances the rich cream sauce.

Storage and Serving

Store leftover Low Carb Creamy Garlic Chicken & Broccoli in an airtight container in the refrigerator for up to 4 days. The sauce may thicken considerably when chilled, so add a splash of chicken broth or heavy cream when reheating. Reheat gently on the stovetop over medium-low heat or in the microwave in 60-second intervals, stirring between each interval. This dish freezes reasonably well for up to 2 months, though the broccoli texture may soften slightly upon thawing. Freeze in individual portions for quick low-carb lunches.

Serve this creamy garlic chicken over cauliflower rice, zucchini noodles, or shirataki noodles for a complete low-carb meal. For those not following a strict low-carb diet, it pairs beautifully with wild rice or whole wheat pasta. Garnish with extra parmesan cheese, fresh parsley, or a squeeze of lemon juice to brighten the rich flavors. A simple side salad with vinaigrette provides a fresh, crisp contrast to the creamy main dish.

Frequently Asked Questions

Can I use frozen broccoli instead of fresh?

Absolutely! Frozen broccoli works perfectly in this recipe. There’s no need to thaw it first—simply add the frozen florets directly to the sauce and extend the cooking time by 2-3 minutes. Frozen broccoli may release slightly more water, so your sauce might need an extra minute of simmering to thicken properly.

Can I use frozen broccoli instead of fresh?

How can I make the sauce thicker without adding carbs?

Xanthan gum is your best friend for thickening low-carb sauces. Start with just ¼ teaspoon sprinkled over the sauce while whisking vigorously to prevent clumping. Alternatively, cream cheese (1-2 tablespoons) adds thickness and tanginess without many carbs. Simply letting the sauce simmer longer also reduces it naturally.

What’s the carb count per serving?

This recipe typically contains 6-8 grams of net carbs per serving (based on 4 servings total), with most carbs coming from the broccoli and small amounts from the cream and aromatics. The exact count depends on portion sizes and any modifications you make.

Can I use chicken thighs instead of breasts?

Yes, boneless, skinless chicken thighs work wonderfully and remain incredibly juicy. They contain slightly more fat, which makes them even more suitable for keto diets. The cooking time remains approximately the same since you’re cutting them into bite-sized pieces.

Why did my sauce separate or look grainy?

This typically happens when cheese is added to sauce that’s too hot or when using pre-shredded cheese containing anti-caking agents. Always remove the pan from direct heat before adding parmesan, whisk constantly, and use freshly grated cheese for the smoothest results.
