Ingredients for Your Garlic Mushroom Chicken
You’ve got this! Here’s what you’ll need to whip up this amazing Garlic Mushroom Chicken. It’s all about simple, good-quality stuff that comes together fast.
Here’s the rundown:
- Olive oil: Just 1 tablespoon to get things started.
- Chicken: Four skinless, boneless chicken breasts. I like to slice them lengthwise so they cook up nice and even.
- Salt and pepper: Always to taste, my friends!
- Mushrooms: About 250g of button mushrooms. Halve them if they’re small, or slice them if they’re bigger.
- Shallots: Two small ones, finely chopped. They give a lovely subtle oniony sweetness.
- Garlic: Three cloves, minced up. Don’t be shy with the garlic here!
- Rosemary: Two sprigs of fresh, or if you don’t have fresh, about 1 teaspoon of dried rosemary works great too.
- Flour: Just 1 tablespoon. This is what helps thicken our dreamy sauce.
- Dry white wine: 80ml. It’s great for deglazing the pan and adds a wonderful depth. If you don’t cook with wine, a little extra chicken stock or even water will work in a pinch.
- Chicken stock: 80ml. Use good quality if you can!
- Double/heavy cream: 375ml. This is the magic that makes the sauce super rich and creamy!
- Dijon mustard: 1 tablespoon. Or go for wholegrain mustard if you like a little more texture and bite!

Essential Equipment for Garlic Mushroom Chicken
You really don’t need much for this Garlic Mushroom Chicken, which is another reason I love it! All you really need is one good, sturdy large skillet. If you have a cast-iron skillet, even better – it holds heat beautifully and gets a gorgeous sear on the chicken. That’s pretty much it!
How to Prepare Garlic Mushroom Chicken: Step-by-Step
Alright, let’s get this amazing Garlic Mushroom Chicken made! It really is as simple as it sounds, and before you know it, you’ll have a gorgeous, restaurant-worthy dinner ready to go. Trust me, your kitchen will smell incredible!
Browning the Chicken
First things first, grab those chicken breasts. Slice them lengthwise so they’re thinner – this helps them cook up nice and even. Sprinkle them with salt and pepper to taste. Now, heat up your olive oil in that large skillet over medium heat. Pop the chicken in, but don’t overcrowd the pan; do it in batches if you need to! Sear them for about 3-4 minutes per side until they’re lovely and golden. They won’t be cooked all the way through yet, and that’s exactly what we want!
Sautéing Aromatics and Mushrooms
Once the chicken is browned, take it out of the pan and set it aside on a plate for a moment. Don’t you dare clean that pan! All those browned bits are pure flavor gold. Now, toss in your halved or sliced mushrooms, a little more salt and pepper, and those fresh rosemary sprigs (or dried, if that’s what you have). Let them cook down and get nice and golden for about 2-3 minutes. Then, add your chopped shallots and minced garlic. Stir and cook for another minute or two until you can really smell that garlic goodness. Next, sprinkle in the flour and give it a good stir. Now for the fun part: pour in the white wine and scrape up all those yummy bits from the bottom of the pan. Let that bubble for half a minute. Pour in the chicken stock, heavy cream, and Dijon mustard. Stir it all together until it’s smooth and starting to look like a dreamy sauce.

Simmering to Perfection
Okay, bring those lovely browned chicken pieces back into the pan, along with any juices they’ve released. Make sure they’re mostly submerged in that glorious sauce. Bring the whole thing up to a gentle boil, then immediately turn the heat down to low. Let it all simmer away, uncovered, for about 10 minutes. This is when the chicken will finish cooking and the sauce will thicken up perfectly. Give it a taste and adjust the salt and pepper if needed. That’s it! Your Garlic Mushroom Chicken is ready to rock! For more delicious skillet meals, check out this recipe.

Tips for the Best Garlic Mushroom Chicken
Want to make your Garlic Mushroom Chicken absolutely sing? Here are a few little tricks I swear by. First off, don’t skimp on the mushrooms! Use fresh, good-quality ones, and don’t be afraid to let them get a nice golden-brown sear. That’s where a lot of nutty flavor comes from. Also, a quick note on the chicken: browning it is key, but remember, it doesn’t need to be *fully* cooked at that first stage. It finishes cooking in the sauce, which keeps it super tender and juicy. And please, taste that sauce before serving! A little extra salt or pepper can make all the difference.

Ingredient Notes and Substitutions
So, let’s chat about a couple of things in this Garlic Mushroom Chicken recipe you might have questions about! First, the mushrooms. While button mushrooms are fantastic and super easy to find, feel free to mix it up! Cremini (baby bella) or even shiitake mushrooms would add an amazing depth of flavor. Just remember to slice any larger ones. And about that white wine? Don’t worry if you prefer not to use it. You can absolutely substitute it with a bit more chicken stock or even some chicken broth for a similar effect.
