From Start to Finish: Creamy Mushroom Chicken with Rosemary Potatoes

Step 1: Prep and Roast the Potatoes
Preheat your oven to 400°F (200°C). Wash and halve the baby potatoes, then toss them in 1 tablespoon of olive oil, the fresh rosemary, salt, and pepper. Spread them out on a baking sheet in a single layer and roast for about 25-30 minutes, or until golden and crisp on the outside and tender inside. Give them a toss halfway through cooking to ensure even roasting.
Step 2: Sear the Chicken
While the potatoes roast, heat the remaining tablespoon of olive oil in your skillet over medium-high heat. Season the chicken breasts generously with salt, pepper, and dried rosemary. Add the chicken to the hot pan and sear for about 5-6 minutes per side until golden brown and cooked through. Remove the chicken from the pan and set aside to rest.
Step 3: Cook the Mushrooms and Garlic
In the same skillet, add the minced garlic and sliced mushrooms. Sauté for 5-7 minutes until the mushrooms are browned and tender, and the garlic is fragrant. Be sure to stir frequently to avoid burning.
Step 4: Make the Creamy Sauce
Lower the heat to medium and pour in the heavy cream. Stir well to combine with the mushrooms and garlic. Let the sauce simmer gently for 3-5 minutes until it thickens slightly. Taste and adjust the seasoning with salt and pepper as needed.
Step 5: Bring It All Together
Return the seared chicken breasts to the skillet, nestling them in the creamy mushroom sauce. Spoon some sauce over the chicken and let everything warm together for a minute or two. This helps the flavors meld and ensures the chicken stays juicy.
Step 6: Plate and Serve
Serve the creamy mushroom chicken alongside a generous helping of rosemary potatoes. Garnish with extra fresh rosemary if desired for a lovely presentation and a burst of herbal aroma.
Holiday-Friendly Variations

- Add a splash of white wine to the mushroom cream sauce for a festive touch.
- Swap baby potatoes for sweet potatoes or butternut squash for a sweeter contrast.
- Incorporate sautéed spinach or kale into the sauce for extra greens.
- Top with freshly grated Parmesan cheese to elevate the creamy mushroom sauce.
- For a smoky twist, add a pinch of smoked paprika to the chicken seasoning.
Don’t Do This
- Don’t skip seasoning the chicken well — it’s key to building flavor.
- Avoid overcrowding the pan when searing chicken; it prevents proper browning.
- Don’t rush the sauce—let it simmer enough to thicken for that perfect creamy texture.
- Refrain from using pre-cooked chicken; fresh chicken breasts yield the best texture.
Storage Pro Tips
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over low heat, adding a splash of cream or broth if the sauce has thickened too much. For the best texture, avoid microwaving as it can dry out the chicken. The rosemary potatoes reheat well in the oven or an air fryer to regain their crispiness.
Creamy Mushroom Chicken with Rosemary Potatoes FAQs
Can I use chicken thighs instead of chicken breasts?
Absolutely! Boneless, skinless chicken thighs work wonderfully in this recipe and tend to stay juicier. Just adjust the cooking time slightly as thighs may take a bit longer to cook through compared to breasts.
What can I substitute for heavy cream?
If you’re looking for a lighter alternative, coconut cream or full-fat coconut milk are great substitutes that maintain creaminess and add a subtle sweetness. For a dairy-free option, oat cream also works well. Just keep in mind the flavor profile will shift slightly.
How do I keep the mushrooms from becoming soggy?
Make sure your mushrooms are dry before cooking and avoid overcrowding the pan. Cooking mushrooms in batches if needed helps them brown nicely rather than steam. Also, cook them on medium-high heat to evaporate moisture quickly.
Can I make this dish gluten-free?
Yes! This recipe is naturally gluten-free as it contains no wheat or gluten ingredients. Just ensure any additional seasoning or broth you use is certified gluten-free if you’re particularly sensitive.
