Ingredients You Will Need

To ensure the cooking process is as seamless and enjoyable as possible, we suggest getting all your components ready before you begin. This small bit of organisation, often called ‘mise en place’, really does make all the difference. Here is the full list of what you will need:

For the Herb Roasted Chicken and Potatoes

4 bone-in, skin-on chicken thighs (about 1kg)
700g Maris Piper or other floury potatoes, scrubbed and cut into 2-inch chunks
1 large onion, cut into wedges
2 tablespoons olive oil
1 teaspoon dried thyme
1 teaspoon dried rosemary
4 cloves garlic, minced
Salt and freshly ground black pepper to taste

For the Creamy Mushroom Sauce

250g chestnut mushrooms, sliced
1 tablespoon butter
1 shallot, finely chopped
2 cloves garlic, minced
60ml dry white wine (like Sauvignon Blanc) or chicken stock
250ml double cream
1 tablespoon fresh parsley, chopped
A squeeze of fresh lemon juice (optional)

Step-by-Step Instructions to Create Your Cozy Dinner

Just follow our straightforward method below to create your own delicious herb-roasted chicken dinner. We’ll walk you through every step to guarantee a wonderful result.

Preheat and Prepare: To begin, set your oven to 200°C (180°C Fan/Gas Mark 6). You will need a large roasting tin or a substantial oven-safe skillet to cook everything in.
Season the Chicken and Potatoes: Place the potato chunks and onion wedges into a large bowl. Drizzle with olive oil and sprinkle over the dried thyme, dried rosemary, minced garlic, salt, and pepper. Mix well until everything is coated, then arrange them in a single layer in your prepared tin. For perfectly crisp skin, pat the chicken thighs completely dry with kitchen paper. Season them well all over before arranging them, skin-side facing up, over the potatoes.
Roast to Perfection: Put the roasting tin into your hot oven and cook for 45 to 55 minutes. You’ll know it’s ready when the chicken skin is golden and crisp, the meat is cooked through, and the potatoes are soft and beautifully browned. To be certain the chicken is done, a meat thermometer inserted into the fleshiest part should register 74°C. For additional advice on safe food preparation, we always refer to the NHS guidelines on food safety.
Create the Creamy Mushroom Sauce: While the chicken and potatoes are in the oven, it’s the perfect time to prepare the sauce. Heat a medium pan over a medium flame and melt the butter. Add the finely chopped shallot and sauté for 2-3 minutes until it has softened. Tip in the sliced mushrooms and continue to cook for 5-7 minutes, allowing them to release their moisture and turn golden brown. Finally, stir in the minced garlic and cook for one more minute until you can smell its aroma.
Deglaze and Simmer: Pour the white wine or chicken stock into the pan to deglaze it, using a wooden spoon to scrape all the flavourful stuck-on bits from the base. Allow this to bubble away until it has reduced by roughly half. Next, stir through the double cream and bring the mixture to a gentle simmer. Let it cook for another 3-4 minutes until it has thickened to a lovely consistency. Finish by seasoning with salt, pepper, and the chopped fresh parsley. We find that a small squeeze of lemon juice at this stage really lifts all the flavours.
Bring It All Together: When the chicken and potatoes are perfectly roasted, take the tin carefully out of the oven. Generously pour the creamy mushroom sauce over everything in the tin. Place it back in the oven for one last 5-minute burst, which gives all the delicious flavours a chance to mingle.
Garnish and Serve: Just before you bring it to the table, scatter over a little more fresh parsley. We think this dish is best served directly from the roasting tin for a wonderfully rustic, communal dining experience.

Our Top Tips for the Perfect Herb Roasted Chicken

Through making this dish many times, we’ve discovered a few simple pointers that can take it from very good to truly exceptional. Here are our most valuable tips for getting it just right.

Choosing the Right Chicken

For this recipe, we strongly suggest using bone-in, skin-on chicken thighs. The bone imparts so much flavour during cooking, while the skin crisps up beautifully for a wonderful textural contrast. You can certainly use chicken breasts if you’d rather, but be mindful to shorten the cooking time a little to ensure they remain moist and tender.

Getting the Potatoes Just Right

Your choice of potato can make a real difference here. We find that a floury type, such as Maris Piper or King Edward, roasts to perfection, yielding a soft, fluffy inside and a crisp golden outside. It’s also important to cut them into uniform 2-inch pieces so that they cook through at the same rate as the chicken.

Mastering the Creamy White Sauce

Patience is key to achieving a rich and velvety sauce. Give the mushrooms enough time to brown properly, as this is where their deep, umami flavour comes from. Once the cream is added, maintain a low heat and allow it to simmer gently until it thickens naturally. Should the sauce seem a little thin, simply let it reduce for a couple more minutes. If it gets too thick, a small dash of milk or stock will loosen it perfectly.

Storage and Reheating Instructions

While this meal is at its absolute best when served fresh from the oven, any leftovers are still a delight. Keep them in a sealed container in the fridge for up to three days. To reheat, transfer everything to an ovenproof dish, cover it with foil, and heat at 180°C (160°C Fan) for 15-20 minutes until piping hot. We sometimes find a splash of stock or milk helps to revive the sauce’s consistency.

What to Serve with Your Cozy Dinner

This creamy mushroom chicken is wonderfully complete by itself, though a couple of simple side dishes can elevate it even further. Our favourite accompaniments are:

A portion of steamed green beans or tenderstem broccoli.
A fresh green salad tossed in a light vinaigrette to provide a sharp contrast to the creamy sauce.
Some crusty bread, which is essential for soaking up every last bit of that wonderful sauce.

For those who enjoy hearty and comforting chicken meals, we think you’ll also adore our The Ultimate Marry Me Chicken Soup Recipe and The Best Creamy Ranch Chicken Recipe Easy Delicious. They both offer unique flavours but are just as satisfying.

Frequently Asked Questions (FAQ)

Can I use chicken breasts instead of thighs?

Of course. For the best results, we suggest using bone-in, skin-on breasts. They do cook more quickly than thighs, so a good tip is to let the potatoes have a 15-20 minute head start in the oven before you add the chicken. This helps everything finish cooking together.

How can I make this dish dairy-free?

Making this dish dairy-free is quite simple. You can swap the butter for olive oil or a dairy-free spread. For the sauce, a good-quality, full-fat coconut milk or another plant-based cream substitute makes an excellent replacement for the double cream. The taste will have a slightly different character, but it will be just as lovely.

What other vegetables could I add?

This recipe is incredibly adaptable. We encourage you to experiment! Root vegetables such as carrots and parsnips can be roasted from the start with the potatoes. Other additions like bell peppers, chunks of courgette, or even Brussels sprouts are wonderful if you toss them in for the final 20 minutes of cooking.

Can I prepare any part of this recipe in advance?

Yes, you can certainly get a head start. To make things easier on the day, you can prepare the vegetables and mix your herbs and seasonings ahead of time. Simply keep the chopped vegetables in a sealed container in the refrigerator. For the best flavour and texture, however, we suggest seasoning the chicken right before it goes into the oven.
