Ingredients and Preparation

Chicken Breasts
The star of the dish—chicken breasts are lean, quick to cook, and great at absorbing the flavors of the creamy sauce. For added juiciness, marinate them in salt and pepper before cooking. You can substitute with boneless thighs if you prefer richer meat.

Mushrooms
These add earthiness and a meaty texture. Button or cremini mushrooms work best, but you can use portobello or even rehydrated dried mushrooms if that’s what you have.

Garlic (Minced & Crushed)
Garlic is the soul of this recipe. The crushed clove infuses the oil early on, while the minced garlic boosts the sauce’s depth later.

Onion
Finely chopped onion creates a sweet-savory base that melds beautifully with the mushrooms.

Chicken Stock, Broth, or Water
Adds moisture and umami to the sauce. If using water, a stock cube can help deepen the flavor.

Heavy Cream (or Fresh Cream/Crème Fraîche)
This is what gives the sauce its velvety body. For a lighter option, you can use half-and-half or milk, though the sauce may be thinner.

Olive Oil and Butter
Olive oil is used to sear the chicken, while butter enriches the mushrooms and keeps the garlic from burning.

Dried Oregano & Fresh Parsley
Oregano gives a herbal note, while parsley brings freshness and color. You can sub with Italian seasoning or thyme.

Parmesan Cheese (or Other Cheese)
Melts into the sauce for extra savoriness. Grana Padano or shredded mozzarella can work in a pinch.

Salt and Pepper
Essential for seasoning both the chicken and sauce. Adjust to taste throughout cooking.

Step-by-Step Instructions

Step 1 Slice the chicken breasts into even 1/2-inch thick filets. This helps them cook quickly and evenly, especially important for beginner cooks avoiding underdone poultry.

Step 2 Season the chicken with salt and pepper and let it marinate for at least 15 minutes to deepen the flavor while you prep the rest of your ingredients.

Step 3 Clean and slice the mushrooms into chunky pieces and finely chop the onion, garlic, and parsley so everything is ready when the pan gets hot.

Step 4 In a skillet, heat olive oil over medium heat and add a crushed garlic clove to infuse the oil with flavor. After about a minute, remove the garlic if it starts to brown.

Step 5 Increase the heat to medium-high and sear the chicken for about 2 minutes per side, just enough to brown it without fully cooking. Then reduce the heat, cover, and let it cook for 3 more minutes.

Step 6 Remove the chicken and let it rest on a plate—this resting period helps lock in the juices and prevents dryness.

Step 7 In the same pan, add the mushrooms in a single layer. Let them brown without crowding the pan, stirring occasionally. Add more oil if needed.

Step 8 Once the mushrooms are golden, reduce the heat and add cold butter. This cools the pan slightly, preventing the garlic and onion from burning when you add them next.

Step 9 Add the onions and sauté until translucent, then stir in the minced garlic for just 30 seconds so it doesn’t become bitter.

Step 10 Pour in chicken stock (or broth or water) and your herbs, increasing the heat to reduce the liquid by half. This intensifies the flavor.

Step 11 Lower the heat and stir in the cream, a bit more pepper, and the grated cheese. Turn off the heat once it’s smooth and creamy.

Step 12 Return the chicken to the pan and nestle it into the sauce. Let it sit for 10 minutes so it absorbs all that garlicky, herby goodness.

Beginner Tips and Notes

If your mushrooms release too much water and start to steam instead of brown, just keep cooking them longer—the water will evaporate eventually. If your chicken browns too quickly, reduce the heat slightly and cover the pan to avoid burning.

When prepping ingredients, use small bowls to organize your chopped veggies, herbs, and liquids. This “mise en place” setup keeps you focused and prevents last-minute scrambling.

Don’t have a garlic press? Use the flat side of a chef’s knife to crush cloves. No heavy cream? Try Greek yogurt for a tangy, lighter twist—just add it at the end off-heat to prevent curdling.

Serving Suggestions

Serve this Best Creamy Garlic Mushroom Chicken over mashed cauliflower or buttery mashed potatoes for a full meal. It also pairs beautifully with roasted green beans or a simple arugula salad tossed in lemon vinaigrette.

For extra flavor, drizzle a bit of lemon juice over the chicken before serving. Want a carb-friendly side? A slice of keto garlic bread will do the trick.

Store leftovers in an airtight container for up to 3 days. The sauce thickens as it cools, so add a splash of broth or cream when reheating to loosen it up. This dish also freezes well—just store the sauce and chicken separately for best results.
