When I made Roasted Green Beans with Mushrooms, Balsamic, and Parmesan I didn’t ever guess that they’d end up being such an enormous hit on the blog. But this recipe has been viewed and pinned literally millions of times. 

I love this recipe and I like to use the lovely thin French beans from Costco. And I do think roasting vegetables is the greatest trick to add to your cooking repertoire, because nothing concentrates and sweetens the flavor of vegetables more than roasting, and these beans are one of the all-time most popular Holiday Recipes on Kalyn’s Kitchen.

What ingredients do you need? 

• mushrooms
• fresh green beans
• Olive Oil (affiliate link)
• Balsamic Vinegar (affiliate link)
• salt and  black pepper
• parmesan cheese

What if you don’t like Mushrooms?

If mushrooms are not a go in your family, instead of roasted green beans with mushrooms I recommend you make Garlic Roasted Green Beans with Shallots and Almonds; those roasted beans are amazing as well!

How to make Roasted Green Beans with Mushrooms, Balsamic, and Parmesan:

(Scroll down for complete printable recipe with nutritional information.)

1. Cut mushrooms into slices that are about 1/2 inch thick. It’s fairly important that mushrooms are the same thickness.
2. Trim both ends of the beans and cut in half.
3. I put the beans and mushrooms into a Ziploc bag, then whisked together the olive oil and balsamic vinegar, poured it into the bag, and squeezed the veggies around until they were all coated with the oil-balsamic mixture.
4. Spray a baking sheet lightly with non-stick spray and spread out beans and mushrooms.
5. Bake in a preheated 450f/230C oven for 20-30 minutes, starting to check then after 20 minutes.
6. When the veggies are done to your liking, put on a platter, season with salt and fresh-ground black pepper to taste, sprinkle with finely grated Parmesan, and devour!

Roasted Green Beans with Mushrooms, Balsamic, and Parmesan are one of the most popular Thanksgiving side dishes on this blog!

Ingredients

• 8 oz. mushrooms
• 1 lb. fresh green beans, preferably thin French style beans
• 1 1/2 T olive oil
• 1 T balsamic vinegar
• salt and fresh ground black pepper to taste
• 2 T finely grated parmesan cheese

Instructions

1. Preheat oven to 450F/230C. Lightly spray a large baking sheet with non-stick spray.
2. Wash mushrooms and let drain (or spin dry in salad spinner, which is what I did.)
3. Cut mushrooms into slices 1/2 inch thick when they are dry.
4. While mushrooms are drying, trim ends of beans and cut beans in half so you have bite-sized pieces. (An easy way to trim them is to gather a small handful of beans, stand them up on cutting board, holding loosely so they will fall down and have ends ends aligned, then trim. Repeat with other end.)
5. Put cut beans and mushrooms into a Ziploc bag or plastic bowl.
6. Whisk together olive oil and balsamic vinegar and pour over, then squeeze bag or stir so all the beans and mushrooms are lightly coated with the mixture.
7. Arrange on large cookie sheet, spreading them out well so beans and mushrooms are not crowded.
8. Roast 20-30 minutes, starting to check for doneness after 20 minutes.
9. Cook until beans are tender-crisp, mushrooms are cooked, and all liquid on the pan from mushrooms has evaporated.
10. Season beans to taste with salt and fresh ground pepper, then sprinkle with finely grated Parmesan. Serve hot.

Notes

I used brown Cremini mushrooms, but any mushrooms will work for this recipe.
