Chicken and Beans Ingredients
- Chicken thighs: Make sure to use chicken thighs here and not chicken breasts. Why not use chicken breasts? Because they are so lean, you will get dry results. Chicken thighs, on the other hand, will produce melt in your mouth chicken. That's what we want here.
- Green beans: Use French beans or string beans.
- Heavy cream: If you worry about this dish being too fatty, you can use half-and-half, or milk, and flour instead of heavy cream. But I you like it to be more creamy and not runny, definitely go for heavy cream.

How to cook creamy green beans and chicken
This one pan recipe is really simple, but I will provide you with all the tips you need.
- Prepare the green beans: Arrange green beans in a microwave-safe dish with ½ cup (125ml) water. Cook in the microwave for 8-10 minutes, until almost done but still crisp.
- Cook chicken: In your large skillet, add olive oil and melt butter, then add sliced chicken thighs. Brown on the first side, then flip and a keep cooking a little longer.
- Add beans and mushrooms: Next, you will move all the chicken to the side and let it cook while you add your beans, garlic and mushrooms in the empty part of the pan. Cook for about 5 minutes until mushrooms are soft, green beans warmed up and the chicken is fork tender!
- Make creamy sauce: Now it's time to add heavy cream and Parmesan. Mix it well with beans, garlic and mushrooms making sure to coat them with sauce. Cook the sauce over medium-high heat for 3-4 minutes, letting it bubble away a little. Stir it frequently and watch it thicken slightly over time.

How to Choose Green Beans
- Green beans is a general name that covers many related types of beans. And it is also used to describe the most common type, which are a variety called Blue Lake. Those are the classic green beans. Yes, the ones we all grew up with and that our grandmothers called string beans! They are very long at 5-7 inches in length.
- French beans, also known as Haricot vert are a thinner, shorter variety. They usually measure about 4-inches long and shorter than regular green beans. The big plus is that they cook in about half the time, and are more tender than Blue Lake green beans.
- I prefer to use French beans, but string beans will work in this recipe as well. Just make sure to cook them slightly longer as they are of a tougher variety than French beans.
Popular substitutions
- Instead of lemon pepper, you can use Umami Seasoning Blend or garlic powder mixed with Italian seasoning.
- Per another reviewer's suggestion, several readers added sherry with the cream & broth.
- If you like to thicken the sauce, create a slurry of cornstarch mixed with existing sauce. Start with 1 teaspoon of cornstarch and stir until smooth paste forms. This is your slurry. Bring to a boil and simmer slightly until any starchy taste has been cooked away. Don't cook longer, though, to avoid cornstarch cooking out.
- Sliced cooked bacon is a great addition and will introduce more flavor and texture.
- For a dairy-free version, try making these with coconut cream instead.
FAQ
- Lower fat alternatives: Evaporated milk or light cream.
- What if my sauce too thin? If sauce is too thin for your taste at the end, then dissolve 1 teaspoon cornflour/cornstarch in 2 teaspoon water and stir that in.
- Sauce thickness - it gets thicker once it cools a bit. I like the sauce to be syrupy and thin so it doesn't stick to the beans thickly which I find a bit too rich for my taste. But if you want the sauce to coat the beans thoroughly, just simmer the cream sauce for extra 2-4 minutes. You can make it so thick that the beans are completely covered in the sauce.
- No microwave? Then bring a large pot of salted water to a boil and add the green beans and cook for 5 minutes until they are tender-crisp. Drain the green beans under cold water to retain their vibrant green colour. You can also plunge them in a bowl of ice water.
What to serve Creamy Beans and Chicken with
Serve over mashed potatoes, of course! I like Buttery Mashed Potato Pie with Herb and Garlic Cream Cheese or Homemade Instant Pot Mashed Potatoes.
Storage/Reheating
- Refrigerate: Store any leftovers in an airtight container in the refrigerator for up to 4 days.
- Reheat gently on the stovetop or in the microwave. Add a splash of broth or heavy cream to the chicken and beans skillet (milk will do too) to add some moisture back (refrigeration is very dehumidifying).

C says
How thin/thick do you slice your chicken?
Olya says
I like to use slices similar to chicken tenders, even half that size.
Jessica Vandyke says
I love this and have made it twice (with a little extra chicken and mushrooms) but my sauce is always so watery-it never thickens. What am I doing wrong??
Olya says
Does the chicken you use have injected with sodium solution (from the manufacturer)? I only use Bell and Evans chicken because I know they air chill them - so no chlorine, no injected liquids (which will both come out during cooking).
Helen says
I made this it was so delicious everyone loved it will be making again and again so easy for me to make after a hard day at work. Thanks Helen
Olya says
Thank you Helen - I am glad it was easy!
Amy says
This recipe was really good, will definitely make again! I didn't have any green beans so threw in fresh spinach instead. Also substituted fresh onions for the onion powder. Can't wait to pick up some green beans and try them in this recipe!
Olya says
Thank you, Amy. Fresh onions win!
Sallie says
Delicious! I skipped the heavy cream /half and half and just thickened the broth with 1 tbsp of gf flour. So good! I also used chicken and mushroom bone broth in place of the chicken broth. Yummy!
Olya says
I liked the idea of using gf flour for thickening!
Linda says
We liked this. Next time I might boost the lemon pepper with some added fresh lemon zest. Or maybe a splash of sherry for added flavor. Thank you for sharing your recipe.
Olya says
Great touch with a splash of terry for the future, Linda!
Corinne Dennie says
Very tasty! However, as it was a 1-skillet meal, and I don't always have a starch with my dinner, I thought it would be plenty for 3 adults, as it's advertised for 4. Guess we just eat more than most? No biggie - will make again, but increase the amount of chicken and use 12oz mushrooms.
Olya says
Wonderful feedback, Corinne, - the more protein we eat, the better it is for our bodies!
Tracey Gordon says
Very tasty midweek meal, made as per the recipe, will make it again but add a chilli and some spinach and see what flavour difference that makes.
Linda says
Followed the recipe exactly. The only change I would make is reduce the cook time for the beans as I prefer them a little crunchier. Still delicious though. I am definitely moving the recipe from my “recipes to try” board to my “favourites” board. Thank you for sharing.
Linda
Olya says
Crunchier beans are amazing! Sounds like you nailed both them and the chicken!
Wade says
This looks amazing, do you use fresh or frozen mushrooms? Frozen is the only way I can find 10oz of mushrooms, not that I mind adding more to the mix lol
Olya says
I used fresh mushrooms, but frozen ones are great as well!
