Costco Garlic Chicken Recipe: Restaurant-Style Perfection at Home

I’ve cracked the code to recreating the beloved Costco garlic chicken at home, and it’s a game-changer. This recipe delivers restaurant-quality results with minimal effort, using simple ingredients and straightforward instructions.

By following this recipe, you’ll achieve perfectly cooked chicken with a rich, aromatic garlic sauce that’s sure to become a family favorite. The result is a dish that’s both comforting and impressive, perfect for a weeknight dinner or special occasion.

Ingredients for Costco Garlic Chicken

Simple ingredients come together to create restaurant-quality Costco garlic chicken at home easily.

For the best flavor, use high-quality Parmesan and fresh garlic. Costco’s version uses a generous amount of garlic, so don’t skimp. Kraft Parmesan works, but grating it yourself makes a difference. Fresh parsley adds a nice pop of color on top.

No heavy cream? Half-and-half is a good substitute, though it’s slightly richer. For an extra garlicky kick, add one more clove. The Italian seasoning blend can vary—some like Penzeys for its balanced flavor. If you prefer a lighter sauce, start with 3/4 cup cream and adjust.

This dish reheats beautifully in the microwave or oven. Store leftovers in an airtight container for up to 3 days. The sauce thickens when chilled, so add a splash of milk or cream when reheating to loosen it up.

Step-by-Step Instructions for Restaurant-Style Garlic Chicken

Here’s the method that delivers perfect, restaurant-style garlic chicken at home every time.

Step 1: Prepare the Chicken and Garlic

Start by pounding the 1.5 lb Boneless, Skinless Chicken Breasts to an even thickness between two sheets of plastic wrap. This ensures uniform cooking and prevents dry spots. Season both sides with 1 tsp Salt and 0.5 tsp Black Pepper—I like to press the seasoning into the meat to help it adhere.

Next, prepare the garlic butter by mixing 0.5 cup Unsalted Butter (softened to room temperature) with 12 cloves Garlic Cloves (peeled and minced), 1 tsp Italian Seasoning, and 0.5 tsp Garlic Powder in a bowl until well combined. The butter should be smooth and fragrant—this will be the flavor foundation of your dish.

Step 2: Dredge and Sear the Chicken

Dredge the seasoned chicken breasts in 1 cup All-Purpose Flour, shaking off any excess. I find that using a shallow dish makes this process neater. Heat 2 tbsp Olive Oil in a large skillet over medium-high heat until shimmering. Sear the chicken for 3-4 minutes per side until it develops a golden brown crust. Transfer the chicken to a plate and tent with foil to keep warm.

The key here is getting a good sear without burning the oil—watch the heat carefully and adjust as needed. You want the chicken to release easily from the pan when it’s ready to flip.

Step 3: Create the Garlic Cream Sauce

In the same skillet (don’t clean it—those browned bits are flavor gold), add the prepared garlic butter. Let it melt over medium heat, stirring occasionally, until it becomes fragrant and slightly bubbly. Pour in 1 cup Heavy Cream and bring the mixture to a simmer. Let it cook for 2-3 minutes until it thickens slightly and coats the back of a spoon.

Stir in 1 cup Parmesan Cheese until melted and smooth. The sauce should be creamy and rich with a beautiful garlic flavor. If it seems too thick, you can thin it with a splash of additional heavy cream.

Step 4: Finish and Serve

Return the chicken breasts to the skillet, spooning some of the garlic sauce over the top of each breast. Let them simmer in the sauce for 2-3 minutes to heat through and absorb the flavors. Garnish with 0.25 cup Fresh Parsley (chopped) just before serving. Serve the chicken with the remaining garlic cream sauce spooned over the top.

The final dish should have perfectly cooked chicken with a golden crust, swimming in a rich, garlicky cream sauce. Each bite should be moist and full of flavor, with the parsley adding a fresh contrast to the richness of the sauce.
