Packed with gooey cheese and punchy garlic, this take on green beans will have even veggie skeptics coming back for seconds. Roasted until they're lightly crisp but still tender, these beans get topped with melty cheese and garlicky goodness, perfect for sprucing up any weeknight or holiday table.
I first threw this dish together when my nephew, who's famous for turning up his nose at anything green, came over. He took one bite, and suddenly he was all smiles, asking for more every visit. It felt like a total win for me as his aunt who just wants him to eat something besides pasta.
Tasty Ingredients
- Fresh green beans: Choose beans that are firm and vivid green. Those will roast up best
- Olive oil: Go for a decent extra virgin bottle for flavor
- Shredded mozzarella cheese: Use whole milk mozzarella if you can—grate it yourself for max gooey-ness
- Minced garlic: Chop up fresh garlic cloves for the strongest flavor (skip the powder!)
- Kosher salt: Its chunky texture spreads flavor evenly
- Fresh ground black pepper: Crack your own pepper for the freshest taste
- Parmesan cheese: Use freshly grated Parmesan to up that nutty, savory vibe
Easy Step-by-Step Instructions
- Get Your Oven Blazing:
- Flip your oven on to 425°F. Give it time to really heat up. While that happens, use cooking spray to coat your baking sheet corner to corner so the beans don’t stick.
- Lay Out Your Beans:
- Spread trimmed green beans out on your pan. One flat layer works best. Give them space—if they're crowded, you'll just end up steaming them, not roasting.
- Mix Up Your Garlic Oil:
- In a bowl, stir together olive oil, Parmesan, garlic, salt, and pepper. Mix it well until it’s a little thick. You want the bits of cheese through the oil so it’ll stick to the beans nicely.
- Coat Those Beans:
- Drizzle your garlicky oil mix all over your beans. Use your hands or a spatula to toss them so every one gets covered. Don’t rush—coating them well means every bite tastes great.
- Put Them in the Oven:
- Roast in your hot oven for 20 minutes. They should stay nice and green, with a few toasty edges. Test by poking one with a fork—it should be soft with just a little snap left.
- Cheese Time:
- Take out the beans and sprinkle them evenly with mozzarella. Spread it so there’s cheese all over—no one likes a cheeseless corner. The heat under will start melting it already.
- Broil for Bubbly Cheese:
- Switch your oven to broil, and move the baking sheet up top. Watch closely—it goes from golden and bubbly to burnt super fast. Pull them when you see deep golden brown spots.
- Dive In and Serve:
- Move the hot, cheesy beans to your serving bowl. When you pull them apart, you’ll see those awesome cheese strings. Dish it up right away for best crunch and gooey melt.

This dish owes everything to garlic. Trust me, fresh-chopped garlic adds a kick you can't get from those jars. My grandma would squish the garlic with salt, turning it into a garlicky paste that made the whole kitchen smell amazing. I still make it her way, and people always rave about the flavor.
Handy Make-Ahead Choices
Want to get a head start? You can trim your beans and mix up the garlicky oil a day ahead. Just stash each in the fridge, keeping them separate. When it’s time to cook, let the oil warm up on the counter before tossing the beans in it and baking as usual. This move is especially clutch when your oven’s already packed for the holidays. The green color stays bright, and the garlicky notes deepen after a chill in the fridge.

Ingredient Swaps
No fresh beans on hand? Go with frozen—just thaw well and dry them off. Need to ditch dairy? Nutritional yeast stands in for Parmesan, and plant-based mozzarella shreds melt up just fine. The taste changes a bit, but it’s still tasty! Want a kick? Toss in a pinch of crushed red pepper flakes to the oil. However you swap things, this side is easy to fit to your needs while keeping its main charm.
Tasty Serving Ideas
This cheesy green bean side sits perfectly next to grilled steak or roast chicken—anything hearty and savory works. Want to keep it meatless? Serve with quinoa and roasted mushrooms for a full meal. Skip the green bean casserole at your next gathering and go with this for fresh flavor and better texture. If you’re hosting, plate the beans hot on a warm platter, shower them with more Parmesan and a scatter of fresh parsley before you bring it out.
Storing & Warming Up
Got leftovers? They last up to three days in a sealed container in the fridge. Forget the microwave—it’ll just make them mushy. Pop them back on a baking tray and heat in a 350°F oven for about 10 minutes to get them hot and revive the cheese. They won’t be as snappy as fresh ones, but still tasty. If you want to meal prep, you can roast the beans and store them without cheese, then add cheese and broil just before serving for the freshest texture.
