Step-by-Step Preparation Guide

Follow these simple, numbered steps for a flawless result. Preheat your oven to 400°F (200°C) before you begin.

Step 1: Prepare and Season the Base

1. Pat the chicken breasts completely dry with paper towels. This is crucial for achieving a good sear.
2. In a large bowl, toss the halved baby potatoes and mushrooms with 1 tablespoon of olive oil, ½ teaspoon of salt, ¼ teaspoon of black pepper, and the smoked paprika (if using).
3. Season both sides of the chicken breasts generously with the remaining salt and pepper.

Step 2: Sear the Chicken & Start the Roast

1. Heat the remaining 1 tablespoon of olive oil in a large, oven-safe skillet or cast-iron pan over medium-high heat.
2. Once the oil is shimmering, add the chicken breasts. Sear for 3-4 minutes per side, until you have a beautiful golden-brown crust. The chicken will not be cooked through at this point. Remove the chicken from the skillet and set it aside on a plate.
3. To the same hot skillet, add the seasoned potatoes and mushrooms. Give them a quick stir to coat them in the pan juices.

Step 3: Roast to Perfection

1. Place the skillet with the potatoes and mushrooms in the preheated oven.
2. Roast for 15 minutes. Then, carefully remove the skillet from the oven (handle will be hot!), push the vegetables to the sides, and place the seared chicken breasts in the center.
3. Return the skillet to the oven and roast for another 15-20 minutes, or until the chicken is cooked through (internal temperature of 165°F / 74°C) and the potatoes are fork-tender and crispy on the edges.

Step 4: Create the Luxurious Sauce

1. Remove the skillet from the oven. Transfer only the chicken and vegetables to a clean plate, leaving any drippings in the pan.
2. Place the skillet back on the stovetop over medium heat. Add the butter and minced garlic. Sauté for about 1 minute until the garlic is fragrant but not browned.
3. Pour in the chicken broth and use a wooden spoon to scrape up all the flavorful browned bits from the bottom of the pan (this is called deglazing and adds incredible depth).
4. Stir in the Dijon mustard and heavy cream. Bring the mixture to a gentle simmer, then reduce the heat to low.
5. Gradually whisk in the grated Parmesan cheese until the sauce is smooth and slightly thickened. Stir in the fresh parsley, thyme, and rosemary. Taste and adjust seasoning if needed.

Step 5: Bring It All Together

1. Return the cooked chicken, potatoes, and mushrooms back to the skillet, nestling them into the creamy sauce.
2. Spoon some of the sauce over the chicken. Let everything heat together for 2-3 minutes on low heat so the flavors meld.

Pro Tips for the Best Creamy Garlic Chicken

These expert tips will ensure your dish is perfect every single time.

• Chicken Consistency: For even cooking, try to select chicken breasts of similar size and thickness. If one end is very thick, you can gently pound it to an even thickness.
• Don’t Crowd the Pan: When searing the chicken, ensure you don’t overcrowd the skillet. Cook in batches if necessary to avoid steaming the chicken instead of searing it.
• Herb Freshness: Using fresh herbs makes a significant difference in the brightness of the sauce. If you must use dried, reduce the amount by about two-thirds (dried herbs are more potent).
• Sauce Thickness: If your sauce is too thin after adding the cheese, let it simmer for a few more minutes. If it’s too thick, simply add a splash of chicken broth or cream to reach your desired consistency.
• Vegetable Variations: Feel free to add other vegetables like asparagus (in the last 10 minutes of roasting) or sun-dried tomatoes for a different twist.

Serving Suggestions & Storage

Serving: This dish is a complete meal on its own! For a finishing touch, garnish with extra chopped fresh parsley and a sprinkle of Parmesan cheese. A simple side of crusty bread is ideal for soaking up every last drop of the delicious sauce.

Storage: Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over low heat or in the microwave, adding a small splash of broth or cream to loosen the sauce if it has thickened.
