For 4 servings
- prep
Preheat oven and prep the baking sheet.
1.Preheat the oven to 425°F (220°C).2.Line a large rimmed baking sheet with parchment paper or a silicone mat.TIPHigh heat is key for getting those slightly charred, blistered edges on the beans. - prep
Trim and season the green beans.
1.Rinse 500g green beans and pat completely dry with a kitchen towel.2.Snap off or trim the stem ends and place beans on the prepared baking sheet.3.Drizzle with 2 tbsp olive oil, sprinkle minced garlic, 1 pinch salt, and 1 pinch black pepper.4.Toss with your hands until every bean is evenly coated.TIPMake sure beans are bone-dry before oiling — moisture creates steam and prevents browning. - prep
Spread beans in a single layer.
Arrange the seasoned green beans in one even layer across the baking sheet. Crowding causes steaming instead of roasting, so use two sheets if needed.
- roast · ~20 min
Roast the green beans until tender and blistered.
Place the baking sheet in the preheated oven and roast for 15-20 minutes, tossing once halfway through. The beans are done when they're tender with lightly charred, wrinkled spots and deep green color.
TIPWatch closely after the 15-minute mark — thin beans can go from perfectly blistered to burnt quickly. - mix
Toss with lemon juice, zest, and parmesan.
1.Remove the baking sheet from the oven.2.Immediately squeeze juice from half the lemon over the hot beans.3.Sprinkle the lemon zest and freshly grated parmesan cheese on top.4.Toss gently to coat, letting the residual heat melt the cheese slightly.TIPZest the lemon before juicing it — it's nearly impossible to zest a squeezed lemon half. - serve
Transfer to a serving platter and serve hot.
Pile the roasted green beans onto a platter and finish with an extra crack of black pepper and a light dusting of parmesan if desired. Serve immediately while warm and crisp-tender.
