Why we love this recipe 🥰
Before I get into the specifics of these super easy roasted string beans with walnuts, can I just ask if anyone else out there is continually stumped by side dishes?
I have more ideas for main courses and appetizers and of course desserts than I can possibly make, but then I inevitably get to that moment where I think oh yeah – vegetables. A vegetable would be good.
And immediately I draw a complete blank that never happens when I am figuring out which of my one million cookie recipes to make next.
As a result, I tend to make what I think of as Old Faithful veggie recipes over and over again. And this plate of green beans with walnuts is one of those – good and good for you and easy and phew! Done with thinking about the side dish for one more supper.
Green beans are happily one of those veggies that you can find all year long, and while of course I love the fresh local beans the best when the seasons start to change and the local beans start to get scarce, this is when I pull out this recipe again and again.
There is something about roasting veggies that brings out every last morsel of flavor.
And I am all about last morsels.
What is the difference between green beans and string beans? 🫛
Nothing! Green beans and string beans are exactly the same thing, and are also sometimes called snap beans or French beans. Whatever you call them, they are pods that are harvested while the seeds inside are still immature and the pod is tender.

Ingredient notes and substitutions 📝
- Green beans: You are looking for the fresh ones in your produce section, and most supermarkets will have them already trimmed and ready for you! If not, just snap off the end bit with the stem on it.
- Walnuts: Look for shelled walnuts in the baking aisle. And you can swap out the walnuts for cashews or pecans or (swoon!) macadamia nuts if you like.

STEP 3: Lay the bean mixture in a single layer on the baking dish and roast them for 12 minutes…give them a toss about halfway through if you can.

Recipe FAQs 🧐
Frozen yes, in a pinch – thaw them out first. Canned, nope. They are too, well, soggy. But honestly, it’s rare that your supermarket won’t have string beans – sometimes already trimmed for you!
Chopped pecans would be delicious in this dish (and if you have a different favorite kind of nut, odds are those will work too). And if you need to leave the nuts out, the roasted beans will still taste marvelous!
You can prep the beans and get everything out and ready to go, but the bean and walnut mixture does need to be roasted ahead of time for the best flavor and texture.

I am THE WORST at side dishes. Seriously. I do love roasted string beans though, so these have my name written all over them!
Somehow I don’t believe you on the whole side dish thing, seeing as you are one of the best cooks I know! :P
Mindy says
Funny, I have an endless list of side dishes that I’m always trying to come up with main dishes for. I’m definitely a sides girl. :)
I made similar beans the other night, but with almonds. We had grilled tri-tip and gratin potatoes to go with. Mmmmmm.
That sounds like my kind of meal! I’m giving almonds a whirl with my string beans next time.
Ala says
As far as side dishes go, I’m actually far better at coming up with a bajillion ideas for them โ and virtually no ideas for a suitable entrรฉe! So I guess we’re in opposite boats here โ maybe we should cook together sometime so that we can fill out the entire menu, right? But the string beans would definitely need to be on the menu, Kate! Hope you’re having a lovely weekend!
Oh my gosh, cooking together would be SO much fun!! Hope you are having a wonderful weekend too. :) xx
grace says
i definitely have a very short list of side dishes that i prepare until either i or my fiance (or both of us) get sick of them. right now, i do my green beans with peppers, basil, and balsamic vinegar, but this is a great option for a replacement dish! :)
Oooh, I love that summery take on green beans – I have to try that one before the snow flies!
Alice @ Hip Foodie Mom says
I love anything roasted. . this side looks fabulous! My go-to for the kids is probably roasted broccoli and cauliflower! my kids love it!
Oh, roasted cauliflower – my heart be still! That’s a great one!
Gayle @ Pumpkin 'N Spice says
I love that you roasted these green beans, Kate! And I’m always stumped by side dishes, too. But these sound just perfect!
Why are side dishes so haaaard? I did come up with an apple potato hash that I am going to post this week, so now I have two current faves!
Nancy Stern says
Was just going to roast the beans from my CSA box but I love the addition of the walnuts. My favorite side dish is Cherry tomatoes sauteed with minced garlic and thyme..
I’m with you on the cherry tomatoes – that’s one of our faves as well!
