- 1/2 teaspoon kosher salt, plus more to taste.
- 1/4 teaspoon freshly ground black pepper.
- 1/4 cup finely grated Parmesan cheese (25 g). Sub: Pecorino Romano for a saltier bite, or nutritional yeast for dairy-free.

Step-by-Step Instructions to Make Roasted Green Beans With Garlic and Parmesan
Preheat the oven and pan
Place a large rimmed baking sheet on the middle rack and preheat to 425°F (220°C) for at least 10 minutes. A preheated pan jump-starts caramelization.
Prep and dry the beans
Rinse, dry thoroughly with towels, and trim the stem ends. Dry beans roast, wet beans steam, so take a minute here.
Season the green beans
In a bowl, toss beans with olive oil, salt, pepper, and minced garlic. If using panko, add it now so it toasts in the oven.
Roast until crisp-tender
Carefully add beans to the hot sheet pan and spread in a single layer with space between. Roast 14 to 18 minutes, shaking once halfway, until blistered in spots and tender-crisp.
Add Parmesan and finish
Sprinkle Parmesan over the hot beans and roast 1 to 2 minutes more to melt slightly. Finish with lemon zest and a squeeze of juice, plus red pepper flakes if you like.
Taste and serve
Season to taste with a pinch more salt and pepper. Serve immediately while the edges stay snappy.
Tips for Success
- Dry thoroughly so the beans roast instead of steam.
- Do not overcrowd. Use two pans if needed for a single layer.
- Preheat the sheet pan. It gives you those delightful charred spots.
- Add fresh garlic to the beans, not directly to the pan, to reduce burning. Garlic powder is a safe swap if your oven runs hot.
- Grate Parmesan finely so it melts quickly and clings to the beans.
Variations of Roasted Green Beans With Garlic and Parmesan
- Lemon-Almond: Add 1/4 cup toasted sliced almonds and extra lemon zest.
- Balsamic-Parmesan: Drizzle 1 to 2 teaspoons aged balsamic over the beans right after roasting, then add Parmesan.
- Spicy Parmesan: Toss with 1/2 teaspoon crushed red pepper or a pinch of cayenne before roasting.
- Herby Upgrade: Add 1 teaspoon Italian seasoning or 2 teaspoons chopped fresh thyme or rosemary.
- Garlic-Herb Panko: Mix panko with a teaspoon of olive oil and a pinch of garlic powder, sprinkle during the last 5 minutes.
Serving Suggestions: What to Pair with Roasted Green Beans With Garlic and Parmesan
- Roast chicken, pork tenderloin, or seared steak for a classic plate.
- Pan-seared salmon or lemony shrimp for a light, bright dinner.
- Creamy mashed potatoes or a parmesan risotto to echo the flavors.
- Pasta nights: toss leftover beans into aglio e olio or pesto linguine.
- Holiday spreads alongside turkey, stuffing, and cranberry sauce.
Storage & Reheating Instructions
Refrigerate leftovers in an airtight container for 3 to 4 days. For best texture, reheat on a sheet pan at 400°F (205°C) for 5 to 7 minutes, or in an air fryer at 375°F (190°C) for 3 to 4 minutes. Microwave works in a pinch but softens the beans. Freezing is not recommended as the texture becomes mushy.
Memories Made Around the Table
These beans are the side I make when friends text that they are five minutes away. I can trim, toss, and roast while setting the table, and that warm, garlicky aroma feels like a welcome all on its own.
FAQs
Can I use frozen green beans?
Yes. Do not thaw. Toss with oil and seasonings, then roast 5 to 7 minutes longer, flipping more often to drive off moisture. Texture will be slightly softer.
How do I make this dairy-free?
Skip the Parmesan and use 2 tablespoons nutritional yeast or a dairy-free grated Parmesan. A squeeze of lemon helps replace the savory pop.
Why are my beans soggy?
They were either wet, overcrowded, or roasted at too low a temperature. Dry them well, spread in a single layer, and keep the oven at 425°F.
Can I prep ahead?
Trim and dry beans up to 24 hours ahead and refrigerate in a towel-lined container. Toss with oil and seasonings just before roasting.
Can I make these in the air fryer?
Yes. Air fry at 380°F (193°C) for 8 to 10 minutes, shaking halfway. Add Parmesan during the last minute.
