- Blanch the green beans in salted boiling water for 3–4 minutes until just tender, then drain and set aside.
- Cook the gnocchi in the same boiling salted water according to package instructions until they float, about 2–3 minutes, then drain, reserving ¼ cup of pasta water.
- Heat olive oil in a large non-stick skillet over medium-high heat and add the gnocchi in a single layer, pan-frying for 2–3 minutes until golden and crispy on one side.
- Push the gnocchi to the side of the pan, reduce heat to medium, and add the butter and minced garlic, cooking for 30 seconds until fragrant.
- Whisk the miso paste into the reserved pasta water until dissolved, then pour into the pan and toss everything together to coat evenly.
- Add the blanched green beans and chilli flakes, tossing over medium heat for 1–2 minutes until well combined and saucy.
- Remove from heat, squeeze over a little lemon juice, and season with black pepper to taste.
- Plate immediately and top with freshly chopped parsley or mint before serving.
Tip: Dissolving the miso in warm pasta water before adding it to the pan prevents it from clumping and ensures it coats every piece of gnocchi evenly — avoid boiling the miso as high heat can diminish its complex flavour.
