Sauteed Green Beans and Mushrooms are a delicious and crunchy combination of green beans and mushrooms sautéed in olive oil and spiced with red peppers. It makes an excellent side dish for a simple meal at home or a holiday gathering!

This is one of my favorite go-to side dishes for potlucks and events. It is always a hit and so easy to make so I can whip it up pretty quickly.
I also really like that it works for most of the special diets out there: paleo, gluten-free, sugar-free, vegan, or vegetarian. Such a win-win for everyone!
I just love the crunchiness of this dish. Actually, that is what I love the most about green beans. It thirstily soaks up any flavors when it is cooked and becomes deliciously satisfying. One cup has 3.4g of fiber which makes you full very easily.
Mushrooms are considered a superfood, as they are known for their wonderful health benefits and healing properties. They are so versatile and can be eaten in so many ways.
They can be fried, grilled, boiled, roasted, sautéed, you name it. They also make an excellent substitute for meat or chicken in dishes since they are vegetarian and vegan-friendly.
Mushrooms also soak up flavors as well, just like green beans so you can just imagine how tasty this combo is!
Ingredients Used
- Green beans: fresh, frozen, or pre-packaged will work just fine.
- Mushrooms: I like to use pre-sliced mushrooms because it’s just more convenient.
- Red onions: I love the milder flavor of red onions and their bright color.
- Mini red bell peppers: because a little heat is good for the soul 🙂
- Coconut Aminos: a salty-sweet condiment with a buttery finish, that makes all the difference in my recipes. This is optional and you can leave it out if you wish.
- Olive oil: for sautéing.
- Spices: cayenne pepper, thyme, salt, and garlic powder. Feel free to substitute with your favorite spices.
How to prepare green beans and mushrooms
You can use frozen or fresh green beans in this recipe. If using fresh green beans, you have to cut off the ends of the green beans.
You can also buy pre-cut green beans with the ends already cut off. Wash the green beans and boil in a pot of water for about 10 minutes, till it becomes just crunchy and not too soft.
Use just enough water to cover the green beans and cover the pot so it can boil faster. Drain the water and set it aside.
Wash the mushrooms and leave them in a colander to drain. You can also pat dry if you prefer.
Chop the onions and mini bell peppers into smaller pieces. Add olive oil to a skillet, add onions and stir for a few minutes.
Add the pepper, mushrooms, coconut aminos, and spices and stir a bit more for about 5 minutes.
Add the green beans and stir for 5 more minutes. Serve and enjoy!

Absolutely delicious! I have made this recipe not only with green beans as written but substituted broccoli for the green beans and it's also delicious. Thanks for sharing this great recipe!
I'm so thrilled you enjoyed it, Martha. Thanks for the review!
For how long would you boil frozen beens for this dish? After boiling for 3-4 minutes they usually start getting soft in my experience 🙂
I've found the easiest way is to thaw it first under running water in a colander, then cook it normally. Thanks for stopping by, Camilla!
I made this as a treat for my hubby (I'm not a huge mushroom fan) and he absolutely loved it! I had to try it after he was raving about it and I ended up having seconds. Delish!
I'm so glad to hear that!
I love simple and easy recipes like this. Love the simple flavors in it too.
Thank you, Lathiya!
What a great combination of ingredients. The red peppers are a perfect addition. I always need new side dish recipes and this one is definitely getting added into the rotation. Thank you for sharing it!
Thanks, Kristin! The red peppers really do give a nice burst of flavor to it.
