Green beans are so versatile and can be made so many different ways. While I do love grilled green beans, roasting is one of my favorite ways to prepare them. When making roasted green beans in the oven, they develop a whole new delicious depth of flavor. And the balsamic marinated mushrooms add a pop of flavor and adds a nice tangy finish.
🛒 Ingredients You'll Need
- Green Beans - fresh is best. Using beans that are bright green and firm in texture is a must when making roasted green beans in the oven. If you use a canned beans, they will turn out mushy. Frozen beans become soggy due to the moisture they hold during the freezing process.
- Oil and Vinegar - use EVOO or a flavored olive oil. The balsamic vinegar helps to slightly marinates the mushrooms, which adds extra flavor to this recipe.
- Parmesan Cheese - it's important to use freshly grated Parmesan cheese. For the freshest, most robust flavor, grate your own cheese from a block of Parmigiano Reggiano Parmesan Cheese. It provides a slight salty taste and has a subtle nutty flavor. If in a hurry, use a bag of grated Parmesan cheese. Stay away from the canned and powdered Parmesan cheese.
See recipe card below for a full list of ingredients and measurements.
📋 Variations and Substitutions
This is a versatile side dish and tastes amazing as is but you can also add some simple additions.
- Fresh squeezed lemon juice after the beans have been roasted helps provide a burst of fresh flavor.
- Top with freshly chopped basil, parsley, chives, or mint.
- To add a bit of heat, add in a teaspoon of red pepper flakes right before roasting.
- After removing the dish from the oven, top with 2-3 slices of salted butter and then stir to coat.
- Top with sliced almonds
🔪 Step-By-Step Recipe Instructions
Start by preheating the oven to 450°F. Roasting requires a higher temperature, anything over 400°F. And to obtain that al dente and crispy tender texture, the oven temperature needs to be high.
While the oven is preheating, trim the tips off the fresh beans. Then, using a sharp knife cut the string beans 2 to 3 times so you have bite-size pieces. Place the cut beans in a colander. If you're not using pre-sliced mushrooms, use a sharp knife to slice them about ¼ of an inch thick.
Next, rinse the vegetables in a colander. Layer paper towels on a counter and pour the beans and mushrooms onto the paper towels. Using another paper towel, gently pat to remove any excess water.
Place the vegetables in a gallon sized plastic bag along with the olive oil and balsamic vinegar. Seal the bag and shake well.
In a 9x13 oven safe dish, add the green bean mixture and spread evenly.
Roast in the oven uncovered for 40-45 minutes. Once done, remove the dish and top with the freshly grated Parmesan cheese. And that's all it takes to make the most delicious roasted green beans made in the oven! Slight crispy and oh so flavorful, these roasted beans are an easy side dish and are incredibly simple to make. The flavors are absolutely delicious!
🙋 Recipe FAQs
The fastest way to trim off the ends is to line up 5-6 beans on a cutting board and then using a large sharp knife, cut the stems off all at once. It makes prep time much easier and a lot faster. You can even do this several days ahead of time and store them in the refrigerator until ready to roast.
Not for this recipe, no. Blanching helps make fresh string beans crisp tender, which is not necessary to do beforehand for this recipe because that's what happens when you roast them in the oven at a high temperature.
💭 Expert Tips
- To save even more time, be on the lookout for bags of green beans that have already been trimmed. These can sometimes be found in the produce section at your local grocery store.
- You can use french style string beans if you want. To make this version, simply cut the tips off in a diagonal direction. Then, slice the beans lengthwise and cut into bite-size pieces. Needa visual? Check out this video: How to Cut French Style Green Beans
- Make these ahead of time by letting all the ingredients marinate overnight in the plastic bag. After all the ingredients have been added to the plastic bag, seal and place in the refrigerator. The flavor is amazing when you let the ingredients marinate overnight in the balsamic vinegar and olive oil.
- For even more flavor, use a flavored olive oil and balsamic vinegar. Garlic infused olive oil with a raspberry balsamic vinaigrette is my favorite taste combination!
- To add even more crunch, roast these in the oven for 30 minutes instead of 45 minutes.
- Store any leftovers in a container with a lid in the refrigerator for 3-4 days. Reheat in the microwave or in the oven.

I made these and are delicious. Everyone loved them. I added almonds to them.
I have also put them in a slow cooker with onion powder and almonds another time. Both were delicious. Will serve to company next weekend.
Enjoy. Thanks for sharing this recipe!
