Roasted Green Beans and Mushrooms (2024)

Who doesn’t love a side dish two-fer? Roasted Green Beans and Mushrooms make a dynamic duo. With just the right touch of bold flavor from garlic and balsamic, they’re an elegant but easy side dish. Fit for any meal, this healthy side dish really shines when paired with beef.

I know I’ve called cauliflower the “current reigning champion in the vegetable world” but I’m second guessing myself now. Because beans, yo.

No, green beans are not as versatile. We can’t mash ’em, we can’t rice ’em, we can’t turn ’em into pizza crust (or hell, maybe we could, but we don’t), but with every new flavor I come up with – and combination thereof, plus switching up the cooking method to suit the ingredients – they just seem to get better and better. Honestly, I don’t know how. Maybe Jack was right and there are really magic beans.

Green beans with garlic are good on every level. Then I added shallots, and leveled up from that. Then I added bacon, and leveled up again. Now I feel like I just beat the proverbial big boss with roasted mushrooms, but I KNOW in my heart, this little game that green beans is playing with me will go on forever. Like Minecraft. (I assume. I have no clue what Minecraft entails. Does it end? Comment below. Really. With two young sons, I need to know this because it absolutely feels like it’s the song that never ends.)

I didn’t set out to beat my high score with this roasted green beans recipe. I just did. (But I’m not calling this my best green bean recipe yet. Because that’s reserved for Princess Crispy Shallots.)

But I promise, I will add crispy shallots (and possibly bacon) to roasted green beans with mushrooms at some point and see if there is an acceptable ratio that doesn’t put me squarely in “I girl-bossed too close to the sun” territory. So check back in 6-8 weeks, which is usually how long it takes me to stop being completely obsessed with a new favorite.

How to Roast Green Beans and Mushrooms

Don’t sleep on this cozy little side dish. Oven Roasted Green Beans with Mushrooms is actually a taste and texture bonanza. Fresh green beans and crimini mushrooms get roasted with toasty pecans and a soy garlic and balsamic marinade for a burst of surprise flavor.

1. PREHEAT. Set oven to 425°F. Line a baking sheet with foil.
2. PREP. Combine fats, liquids and garlic in a dish. Whisk until well combined. Pour half the sauce over mushrooms in bowl and toss until coated. Pour the other half over green beans in a second, separate bowl, and toss.
3. ROAST. Arrange mushrooms on baking sheet in a single layer, then roast mushrooms 30 minutes, tossing once halfway through.
4. ADD GREEN BEANS. Add the green beans to the baking sheet. Return to the oven, and roast the vegetables 10 minutes more.
5. CRUNCH. Add the pecans, return to the oven, and roast 5 minutes.
6. FINISH. Season with salt and pepper, and serve immediately.

Chef’s Tips

• Not all veggies roast at the same rate (we covered this in detail here). And that’s okay! This is still one a one sheet pan recipe, but done in stages – start the mushrooms first, then add the green beans about halfway through. Trust the process and be rewarded.
• If you want to save yourself some cleanup, use the same bowl to sauce the green beans after you’ve put the mushrooms in the oven.
• You don’t need to toast the pecans prior to roasting, unless they were raw to begin with. If you have raw pecans, spread them over a small baking sheet and roast separately. Add them to the oven along with the green beans for 10 minutes until lightly browned and fragrant. Don’t cook the final 5 minutes, simply toss toasted pecans with the roasted vegetables.
