This is one of my favorite recipes from my mom, and she makes it almost weekly — sometimes as a warm salad with dinner, sometimes as a side dish for a bigger spread, sometimes as part of her meal prep for the week.
It’s the recipe I grew up eating and the one I still make more than almost anything else she taught me.
It’s delicious as a warm salad right when it’s made, and it’s just as delicious after a night in the fridge, when the beans have absorbed even more of the dressing and the whole thing tastes deeper and more flavorful.
The one thing that makes this recipe different from every other green bean side is the sesame.
Toasted sesame seeds get ground into a coarse, oily meal — the Japanese technique behind goma dare — and then whisked with soy sauce, sugar, and a little toasted sesame oil.
The ground sesame is what gives the dressing its body and depth. Whole sesame seeds sprinkled on top are just garnish. Both matter, but only one is the point.
Here’s the honest part: the grinding is an extra step, and you can skip it if you’re short on time or don’t have a mortar or a spice grinder.
It’ll still be good. But if you have two minutes and the tools, it’s the difference maker — the ground sesame is what turns this from a nice green bean side into something that tastes like it came from a restaurant. The aroma alone is worth it.
The recipe makes 4 side servings and takes about 10 minutes of prep and 8 to 10 minutes of cooking. It’s a warm salad that works as a side for grilled chicken, salmon, steak, or rice bowls, and it’s the kind of thing that converts people who thought they didn’t like green beans.
Why This Recipe Works
String bean salads go wrong in three specific ways: bland dressing, soggy beans, and beans that don’t hold the dressing. Here’s how this version solves each one.
1. Grind the Sesame Seeds Into a Coarse Meal
Whole sesame seeds sprinkled over green beans are a garnish, not a dressing. Grinding toasted sesame seeds into a coarse, oily meal releases their oils and turns them into the base of a real Japanese-style dressing. The ground seeds give the dressing body and depth, and the whole seeds on top give it texture. You need both, but the ground ones are doing the heavy lifting. This step is optional, but it’s the one that makes the biggest difference.
2. Toss the Hot Beans Into the Dressing
The beans go into the dressing while they’re still hot from the skillet. The residual heat helps the sugar dissolve, loosens the ground sesame paste, and lets the beans absorb the dressing as they cool. Cold beans tossed in dressing just sit there — the dressing pools at the bottom of the bowl. Hot beans absorb it.
3. Sear the Beans in a Dry-Enough Pan
The beans need to be completely dry before they hit the oil. Wet green beans steam instead of searing, and steamed green beans have no blistered spots, no texture, and no flavor. Pat them dry with a clean kitchen towel, and get the skillet hot before they go in.
Ingredients That Matter
Fresh string beans (green beans). One pound, ends trimmed and patted completely dry. Fresh beans are essential — frozen or canned beans won’t sear, and they’ll turn mushy when tossed with the dressing.
Avocado oil. One tablespoon. Avocado oil has a high smoke point, so it holds up to the sear without burning. Any neutral high-heat oil works.
Toasted white sesame seeds. Two tablespoons, divided. One tablespoon gets ground into the dressing; the other is reserved for finishing. Toasted seeds have more flavor than raw ones — if you only have raw sesame seeds, toast them in a dry skillet for 2 to 3 minutes before using.
Low-sodium soy sauce. One tablespoon. The salt and umami in the dressing. Low-sodium lets you control the final salt level.
Granulated sugar. Two teaspoons. The sweetness that balances the soy and sesame.
Toasted sesame oil. Half a teaspoon. The aroma. A little goes a long way — sesame oil is potent.
Fine sea salt. A small pinch, for the beans as they sear. Taste the finished dish before adding more — the soy sauce carries salt.

Tips and Troubleshooting
The beans turned out soggy. They were wet when they went into the pan, or the skillet wasn’t hot enough. Pat the beans completely dry and get the pan shimmering before they go in.
The dressing is too thick. The ground sesame paste absorbed more liquid than expected. Add a splash of water or soy sauce, 1 teaspoon at a time, until it reaches a pourable consistency.
The dressing is too thin. The sesame seeds weren’t ground enough, or the sugar wasn’t fully dissolved. Grind the seeds into a coarser meal and whisk the dressing until the sugar dissolves.
The beans are bland. The dressing didn’t have enough soy sauce or salt, or the beans weren’t hot when they went into the dressing. Toss hot beans into the dressing, and taste the dressing before pouring it on.
The beans are too firm. They were thick and needed longer to cook, or the pan wasn’t hot enough. Add 1 tablespoon of water and cover the pan for 1 to 2 minutes to steam them through without losing the sear.
The sesame flavor is weak. The sesame seeds weren’t toasted, or the sesame oil was skipped. Toast the seeds first, and use the full half-teaspoon of sesame oil.
The whole sesame seeds fell to the bottom. They were added to the dressing instead of sprinkled on top. Ground seeds go in the dressing; whole seeds go on top at the end.
The beans got mushy the next day. That’s expected — the beans keep absorbing the dressing as they sit. If you want them crisp for day two, dress them right before serving instead of ahead of time.
Substitutions and Swaps
String beans → haricots verts, wax beans, or long beans. Same quantity. Haricots verts are thinner and cook faster — check at 5 to 6 minutes. Long beans are the traditional choice for Chinese green bean recipes and need 2 to 3 extra minutes.
Avocado oil → canola or vegetable oil. Same quantity. Any high-heat neutral oil works.
Low-sodium soy sauce → tamari or coconut aminos. Same quantity. Tamari makes the recipe gluten-free; coconut aminos are sweeter and need a pinch of salt.
Granulated sugar → honey or maple syrup. Same quantity. Honey is slightly sweeter; maple syrup adds a deeper note.
Toasted white sesame seeds → black sesame seeds. Same quantity. Black sesame seeds have a slightly earthier flavor and make a striking gray-black dressing.
Skip the sesame grinding. If you don’t have a mortar and pestle or spice grinder, use 2 tablespoons of tahini in place of the ground sesame seeds. The dressing is smoother and slightly less textured, but the flavor is very close.
For a spicy version: add ½ teaspoon of red pepper flakes to the dressing, or a spoonful of chili crisp on top before serving.
For a Chinese green bean version: add 2 cloves of minced garlic to the skillet with the beans and a splash of rice vinegar to the dressing.
For a marinated beans version: dress the beans and refrigerate them for at least 2 hours, or overnight. They’ll absorb more of the dressing and the flavor will deepen.
For a string beans and potatoes version: boil 1 pound of baby potatoes until tender, halve them, and toss them with the green beans and dressing.
Storage and Reheat
Refrigerate leftovers in an airtight container for up to 4 days.
Meal prep: prepare the sesame dressing up to 4 days ahead and refrigerate separately. Cook and dress the green beans closer to serving time for the best texture.
Serving leftovers: enjoy chilled or allow the salad to come closer to room temperature before serving. The beans will soften slightly as they sit, and the flavor will be deeper than on day one.
No reheating needed. This is a warm salad — it’s best served warm or at room temperature, but it’s just as good cold from the fridge.
Food safety: store leftovers within 2 hours of cooking. Discard anything left at room temperature longer than 2 hours.
Notes
The ground sesame seeds are the dressing — whole seeds sprinkled on top are a garnish, not the base. Toss the hot beans into the dressing off the heat so they absorb the flavor as they cool.
Pat the beans completely dry before they hit the skillet; wet beans steam instead of searing.
The beans keep absorbing dressing as they sit, so they get more flavorful the next day — dress them 10 to 15 minutes ahead for the best flavor. If you don’t have a mortar and pestle or a spice grinder, use 2 tablespoons of tahini in place of the ground sesame seeds.
Serve warm or at room temperature. Leftovers keep 4 days in the fridge; store the dressing separately if you’re prepping ahead. Nutrition is an estimate and varies by soy sauce brand.
Warm String Bean Salad (Sesame Green Bean Salad)
Tender, skillet-seared green beans tossed in a savory-sweet sesame dressing made with freshly ground toasted sesame seeds, soy sauce, and a touch of sesame oil — a 20-minute warm salad that's just as good chilled the next day.
Ingredients
Green Bean Salad
- 1 lb fresh string beans (green beans), ends trimmed and washed
- 1 tablespoon avocado oil
- Small pinch of fine sea salt
Sweet Sesame Dressing
- 2 tablespoons toasted white sesame seeds, divided
- 1 tablespoon low-sodium soy sauce
- 2 teaspoons granulated sugar
- ½ teaspoon toasted sesame oil
Instructions
- Prepare the Green Beans: Wash the green beans and pat them completely dry with a clean kitchen towel. Trim the stem ends. If the beans are particularly long, cut them into about 2-inch pieces.
- Grind the Sesame Seeds: Place 1 tablespoon of toasted sesame seeds in a Japanese suribachi mortar or small spice grinder. Grind until the seeds are partially broken down into a coarse, slightly oily meal. You want some texture rather than a completely smooth paste. Reserve the remaining tablespoon of whole sesame seeds for finishing. If you don't have a mortar or grinder, see the substitution note — tahini works in place of the ground sesame.
- Make the Sesame Dressing: In a large mixing bowl, combine the ground sesame seeds, soy sauce, sugar, and toasted sesame oil. Whisk until the sugar begins dissolving and the mixture forms a thick, fragrant dressing.
- Sear the Green Beans: Heat the avocado oil in a large skillet over medium-high heat. Add the dry green beans and a small pinch of salt. Cook 7 to 9 minutes, tossing occasionally, until the beans develop lightly blistered brown spots and become tender-crisp. If the beans are particularly thick and still too firm, add 1 tablespoon of water and cover for 1 to 2 minutes to help finish cooking.
- Toss With the Sesame Dressing: Remove the skillet from the heat. Immediately transfer the hot green beans into the bowl with the sesame dressing. Toss thoroughly with tongs until evenly coated.
- Finish and Serve: Sprinkle the remaining whole toasted sesame seeds over the green beans. Serve warm or at room temperature as a flavorful side dish.

Frequently Asked Questions
What is a string bean salad?
A string bean salad is a salad made with green beans — usually blanched, steamed, or seared, then tossed with a dressing. This version is a warm salad: the beans are seared in a skillet, then tossed into a warm sesame-soy dressing while they’re still hot.
What is goma dare?
Goma dare is a Japanese sesame dressing made from ground toasted sesame seeds, soy sauce, sugar, and rice vinegar or dashi. It’s the base of this recipe, simplified to four ingredients.
Can I skip grinding the sesame seeds?
Yes. The grinding is the extra step that makes the biggest difference in aroma and flavor, but you can skip it if you’re short on time or don’t have a mortar or spice grinder. If you skip it, use 2 tablespoons of tahini in place of the ground sesame seeds — the dressing is smoother and slightly less textured, but the flavor is very close.
Can I use frozen green beans?
No — frozen green beans won’t sear and they’ll turn mushy when tossed with the dressing. Use fresh green beans for this recipe.
Can I make the dressing ahead of time?
Yes. The dressing keeps 4 days in the refrigerator in a sealed jar. Whisk it again before using — the ground sesame settles to the bottom.
Why did my green beans turn out soggy?
They were wet when they went into the pan, or the skillet wasn’t hot enough. Pat the beans completely dry with a clean kitchen towel and get the pan hot before they go in.
Can I make this spicy?
Yes. Add ½ teaspoon of red pepper flakes to the dressing, or a spoonful of chili crisp on top before serving.
Is this gluten-free?
Only if you use gluten-free soy sauce (tamari) or coconut aminos. Standard soy sauce contains wheat.

Closing
This warm string bean salad is one of my favorite recipes from my mom, and the thing that changed everything for me was learning to grind the sesame seeds instead of sprinkling them whole.
She always did it that way — I didn’t realize how much of the flavor came from that one step until I tried skipping it.
The ground sesame is the difference between a nice green bean side and something that tastes like a restaurant plate.
If you make it with tahini instead of grinding the seeds, or add chili crisp for a spicy version, let me know how it turns out in the comments.
