    Roasted Green Beans & Mushrooms with Walnuts [close]
    This Roasted Green Beans and Mushrooms recipe is one from my side dish arsenal.

    Side dish arsenal? Yes! It's my collection of fast, effortless side dishes--things that can be thrown together quickly so when my main dish requires a little more work, I can make a side that's pretty much hands-off. They're also a little bit lower in calories, so they pair perfectly with heavier entrees. I've shared a lot of these recipes here already--Barbecue Zucchini Fries, Roasted Broccoli, and Roasted Cauliflower & Kalamata Olives are a few of my favorites. I make sides like this all the time--I used to rely on frozen veggies in such cases, but I've been working on building a collection of go-to recipes that take only a few more minutes than those frozen vegetables, but taste a million gazillion (actual number!) times better.

    Green Beans & Mushrooms
    This recipe really couldn't be much easier--the most time-consuming part is trimming the green beans. (And trust me, if you've never had roasted green beans before, the 5 minutes of trimming and cutting is well-worth the effort.) Once you've cut the beans and mushrooms, you throw them onto a baking sheet with the walnuts, spray them with cooking spray, and 15 minutes later, you have a fresh, delicious (not to mention healthy!) side dish that your whole family will love.

      I need to build up my side dish arsenal. More often than not I pop a bowl of frozen peas in the microwave to go with my meals. To me its super tasty, but not so exciting 😀

        Yeah, I used to do the same thing, except with other frozen veggies instead of peas. Then I got tired of them and started adding fresh herbs, flavored oils, etc. And then I got to the point where I couldn't even look at frozen veggies without getting a little sick. 😉

      Love this twist on a basic green been dish! I bet the truffle oil tastes great with it, so I'll have to go find it.

        Truffle oil is one of those things you either love or hate! Personally, I can't get enough of it and I love that you can add a tiny bit of it to something and that's all you need.

      I love these easy side ideas cuz I'm stuck in the frozen veggie rut. My kids pretty much only eat peas or broccoli but I get so bored with that! Thanks for more roasted yumminess!

        I used to make Trader Joe's frozen broccoli, asparagus, or haricot vert at least a few times a week and I got SO sick of them, which is why I started trying to find and come up with recipes like this one. I know a lot of kids are grossed out by mushrooms, but roasted green beans with just a little olive oil and sea salt are pretty kid friendly!

        I'm a little bit obsessed with roasting veggies--I do it at least once a week. When I added this to my recipe index, I was kind of embarrassed by the number of roasted veggie recipes I had listed. 😉

      These look so good. I would have never thought of walnuts and they are such a healthier choice in the nut family.

        I love walnuts with green beans and mushrooms--they have a nice, earthy flavor that goes well with both of those veggies.

        I have a big bag of walnuts in the pantry, so I'm constantly trying to put walnuts into random recipes. 😉

      That is something I should have done ages ago....(insert a lightbulb) Terrific idea! I will be compiling my list of dependable and quick and of course easy side dishes for when the need arises. This will definitely be in there. Thanks!

      I've never been fond of mushrooms (except with hominy) but that looks really good. I've never roasted green beans before but I must definitely try this soon.

        You can always omit the mushrooms and double the green beans. They are so delicious when you roast them!

        You can serve them with just about anything! I mean, I wouldn't pick an ethnic main dish like something Thai or Indian, but pretty much any main dish will work with green beans & mushrooms.

      Wow, what a savory, delicious dish! I used a mix of mushrooms from the farmer's market and purple podded pole beans with my walnuts. Then I ate a whole bowl for dinner. Thanks for this marvelous recipe, I'll definitely be making it again soon!

      So I have some interest in making this at a youth camp I'll be cooking at in a few weeks. But I'll be cooking for 100, not 4. Don't really want to spend the time trimming green beans and quartering fungus for 100 servings. Is this likely to still be decent using frozen green beans and sliced mushrooms?
