Ingredient insights: what makes these green beans special.
- Green beans: Fresh and bright green—look for firm, unblemished beans with a snap. They’re the backbone of this dish, giving that perfect bite.
- Lemon: Adds a fresh, zesty brightness that cuts through the smokiness. Use freshly squeezed for the best zing. You can swap with lime for a different citrus note.
- Olive oil: A good drizzle helps the beans crisp up and enhances flavor. Use extra virgin for richness, or avocado oil for a neutral, high-heat option.
- Salt: Enhances the natural sweetness. Adjust to taste, but don’t skimp. A finishing sprinkle makes all the difference.
- Parmesan or herbs: Optional but adds umami and freshness. Use freshly grated cheese or chopped herbs for maximum flavor.
