Why You Will Love This Recipe
These blistered green beans with scallion oil are a labor of love that takes minimal effort. The high heat used for blistering creates a wonderful slight char, enhancing the natural sweetness of the beans while softening them just enough to remain crisp-tender. The homemade scallion oil permeates every bite, delivering an aromatic punch of fresh onion flavor that complements nearly any main course, from roasted chicken to grilled steaks. It’s fast, visually appealing, and easily scalable for entertaining.
Ingredients
- 1 pound fresh green beans, trimmed
- 1/2 cup neutral oil (such as canola, vegetable, or grapeseed oil)
- 1 large bunch scallions (green onions), thinly sliced, white and green parts separated
- 2 cloves garlic, thinly sliced
- 1/4 teaspoon kosher salt, plus more for seasoning
- Freshly ground black pepper to taste
- Optional: 1/2 teaspoon toasted sesame seeds, for garnish
Step-by-Step Instructions
- Prepare the Scallion Oil: Combine the neutral oil and the white parts of the sliced scallions in a small, heavy-bottomed saucepan. Heat over medium-low heat.
- Infuse the Oil: Slowly bring the oil mixture to a gentle simmer. You want the scallions to slowly infuse the oil without burning. This should take about 5 to 8 minutes.
- Add Aromatics: Once the white parts of the scallions are slightly softened, add the sliced garlic. Continue to heat gently for another 1 to 2 minutes, watching very carefully to ensure the garlic does not brown or burn—burnt garlic becomes bitter.
- Strain the Oil: Remove the saucepan from the heat. Carefully strain the hot oil through a fine-mesh sieve into a heatproof bowl. Discard the solids (or save them for another use, like mixing into fried rice). Set aside the fragrant scallion oil.
- Blister the Beans: Heat a large skillet (cast iron works best for intense heat) over high heat until very hot. Add about 2 tablespoons of the prepared scallion oil to coat the bottom of the pan.
- Cook the Beans: Add the trimmed green beans to the hot skillet in a single an even layer if possible (work in batches if necessary to avoid overcrowding the pan, which steams them). Cook undisturbed for 3 to 4 minutes until the beans develop significant char and blistering on one side.
- Toss and Season: Toss the beans and continue to cook for another 2 to 3 minutes until they are tender-crisp throughout and nicely blistered on several sides.
- Finish the Dish: Transfer the blistered green beans to a serving platter. Drizzle generously with more of the warm scallion oil, and season immediately with kosher salt and freshly ground black pepper.
- Garnish: Sprinkle with the reserved green parts of the scallions and the toasted sesame seeds, if using, before serving immediately.
Expert Tips / Pro Tips
Achieving the perfect blister on your green beans is crucial for this recipe’s success. Use the highest heat your pan can handle. A cast iron skillet retains heat exceptionally well, which promotes immediate searing rather than steaming. If your pan isn’t hot enough, the beans will release too much moisture and become soggy. Work in batches if necessary to ensure the beans sit directly on the hot surface; crowding the pan is the enemy of blistering!
Variations & Substitutions
For an added layer of umami, substitute 1 tablespoon of the neutral oil with toasted sesame oil when creating the scallion oil infusion—though this change should be done sparingly as sesame oil is potent. If you enjoy spice, add a few dried red pepper flakes to the oil along with the garlic for a subtle kick. For a richer flavor profile, use brown butter instead of neutral oil for the initial sauté, though this technique makes achieving a clean “blister” slightly harder.
Serving Suggestions
These blistered green beans with scallion oil are versatile. They pair beautifully as a bright, fresh counterpoint to rich roasted meats like Prime Rib or Herb Roasted Chicken. For a vegetarian meal boost, serve them alongside crispy tofu or alongside a simple miso-glazed salmon. They also make an excellent addition to a main-course grain bowl featuring quinoa or rice.
Storage, Freezing & Reheating
It is best to enjoy these beans fresh immediately after preparation, as the texture deteriorates upon refrigeration. If you have leftovers, store them in an airtight container in the refrigerator for up to 2 days. To reheat, the best method is to toss them back into a dry, very hot skillet for 1-2 minutes to refresh the char. Freezing is generally not recommended as the texture will become mushy upon thawing.

FAQ
Can I use frozen green beans instead of fresh?
While fresh green beans yield the best flavor and texture for blistering, you can use frozen ones in a pinch. However, you must completely thaw them and pat them extremely dry before introducing them to the hot skillet. Even then, the chance of achieving a true blister is significantly reduced compared to fresh beans.
How do I keep the scallion oil from burning?
The key to preventing scorching is low and slow heat when infusing the oil. Keep the temperature at a gentle simmer over medium-low heat. The scallion whites and garlic should soften and become fragrant, not brown quickly. Once infused, remove the solids immediately to stop the cooking process.
What is the best way to trim green beans?
To trim green beans, snap off or use a knife to cut off the tough, woody stem end (the very tip where they attached to the plant). If the bottom tip is also ragged or woody, trim that off as well. The middle section is what you want for this recipe.
Blistered Green Beans with Scallion Oil
Ingredients
Method
- Prepare the Scallion Oil: In a small saucepan, pour the 1/2 cup of neutral oil. Add the sliced scallions and garlic. Heat over medium-low heat, allowing the scallions and garlic to slowly infuse the oil. This should take about 8-10 minutes. Do not let them brown or burn, just soften and turn pale golden.
- Once the scallions are softened, remove the pan from the heat. Stir in the soy sauce and toasted sesame oil. Set aside to steep while you cook the beans.
- Blister the Green Beans: Heat 2 tablespoons of neutral oil in a large, heavy-bottomed skillet (cast iron works best) over medium-high heat until shimmering.
- Add the trimmed green beans to the hot skillet in a single layer. Do not overcrowd the pan; cook in batches if necessary. Let the beans cook undisturbed for 3-4 minutes until the bottoms are significantly charred and blistered. Toss them lightly and cook for another 2-3 minutes until tender-crisp.
- Season the beans immediately with kosher salt and black pepper while they are still hot in the skillet.
- To serve, transfer the blistered green beans to a serving platter. Strain the flavorful scallion oil (discarding the solids, or reserving them for garnish if preferred) and drizzle generously over the hot beans. Toss gently to coat and serve immediately.
