Step 1: Marinate the Chicken

In a mixing bowl, combine olive oil, lemon juice, garlic powder, smoked paprika, salt, black pepper, onion powder, and red pepper flakes.

Add the chicken bites and toss to coat evenly.

Cover and let the chicken marinate for at least 30 minutes (or up to 4 hours for deeper flavor).

Step 2: Grill the Chicken

Heat a grill pan over medium-high heat and lightly grease it.

Arrange the marinated chicken in a single layer.

Grill for 3-4 minutes per side, flipping halfway through, until golden brown and cooked through.

Remove from heat and set aside.

Step 3: Make the Creamy Garlic Sauce

In a small saucepan over medium heat, melt butter.

Add minced garlic and sauté for 30 seconds until fragrant.

Pour in chicken broth and let it simmer for 2 minutes.

Reduce heat to low, then stir in heavy cream and Parmesan cheese, mixing continuously.

Simmer for 3-4 minutes until the sauce thickens.

Stir in lemon zest, salt, and black pepper for flavor balance.

Step 4: Combine & Serve

Add the grilled chicken bites into the sauce and toss to coat evenly.

Let them simmer for 1-2 minutes to absorb the flavors.

Garnish with fresh parsley and serve hot.
