If you’re looking for an easy vegetable side dish for Thanksgiving or a weeknight dinner, try these roasted garlic parmesan green beans. I toss the veggies in a mix of garlic, lemon juice, olive oil, salt and pepper before they go in the oven. Then in the last few minutes of roasting time, I sprinkle them with grated parmesan, which quickly melts into the crisp-tender green beans.

Why You’ll Love This Recipe
There is something so wonderful about a simple single vegetable side dish that delivers on taste, and these roasted greens do just that. Inspired by classic green beans almondine, this recipe is an oven-roasted version with lemon, garlic and toasted almonds.
It’s the perfect way to include fresh green beans at Thanksgiving. I know I’m not the only one who says no thanks to green bean casserole. This green bean side is much lighter and healthier and it really showcases the vegetables. The melted parmesan adds a touch of creaminess and umami.
You can repurpose leftovers. I add them to an Italian chopped salad, or I toss them with cooked grains. You could use them in this green bean and white bean quinoa recipe.
The Ingredients

This is what you need:
- Green beans: You can find trimmed green beans in packages at the grocery, but it is also easy to trim them if necessary. Just put the green beans in a row on a cutting board and slice off the stem ends with a sharp chef’s knife.
- Garlic: Roasting garlic tones down it’s flavor, so this recipe won’t turn out too garlicky. To avoid the burning the garlic, you have to finely mince it into a paste. I do this with a microplane or the fine holes of a grater. Please don’t substitute with garlic powder.
- Parmesan cheese: There are brands that make plant-based, dairy-free cheese if you need the recipe to be vegan.
- Almonds: Toast the sliced almonds on a baking sheet in a 350-degree F oven for 5-7 minutes. This will bring out their fantastic nutty flavor.
- Lemon: I use the juice in the marinade, and I toss the zest with cheese, nuts, fresh herbs and roasted green beans.
- Parsley: I use chopped parsley for herbs in this recipe. If you like onion flavor, you can also include minced chives.
- Olive oil: Use extra-virgin olive oil for the best flavor.
- Kosher salad and black pepper season the raw green beans before roasting.
How To Make These Roasted Garlic Parmesan Green Beans
Preheat the oven to 425 degrees F.
1. Make the marinade. Whisk the oil, lemon juice, garlic, salt and pepper in a bowl big enough for the green beans.
2. Stir the green beans into the garlic-oil mixture.

3. Put the green beans on a rimmed baking sheet. They should be in a single layer without overlapping. Leave the extra garlic-oil mixture in the bottom of the bowl.
4. Roast the green beans. Give them 10 minutes before scattering grated parmesan on top. Continue roasting for 2-3 minutes. The cheese will melt, and the green beans should be tender, but still crisp with some brown spots.

5. Toss the green beans with almonds, parsley and lemon zest. I do this on the sheet pan, so I don’t have wash another bowl. Then I spoon the green beans in a serving dish and garnish with additional Parmesan.

Serving
These roasted green beans are great with spring, summer and fall dinners with Mediterranean flavors. They go really well with proteins like roasted chicken, salmon or steak. As mentioned, they are wonderful for holidays such as Thanksgiving, Christmas or Easter and work with my go-to roasted turkey breast recipe.
Leftovers & Storage
This green bean side dish is best served warm. If you do have leftovers, let them cool to room temperature. Then transfer them to an airtight container saving them up to 3 days in the fridge. You can reheat them in a 350-degree F oven.
You can repurpose the leftovers in egg dishes like frittatas, scrambles and omelettes. Chop them into bite-sized pieces, so they warm quickly in the skillet with a little oil before you add eggs. I also like eating them cold in salads.
Recipe Tips
- You can use French green beans. Just keep in mind that they are more slender than regular green beans, so they will roast more quickly.
- Toast the nuts in advance. When I buy a bag of nuts like almonds, walnuts or pine nuts, I roast all of them on a sheet pan (350 degrees F for 5-7 minutes). Then I put them to a storage container, so I have toasted nuts ready for salads, sides and snacking.
- Mince the garlic into a paste. By doing this, the garlic almost disappears into the oil. If you have tiny pieces of minced garlic, they will burn in the oven.
- You don’t have to line the baking sheet with aluminum foil or parchment paper. The oil that you toss the green beans in will prevent them from sticking to the pan. Also, the green beans will be more like to blister when they make direct contact with the hot metal of the pan.
- Because this side cooks quickly, you can make it the last thing on your to-do list. Just have all the ingredients prepped. Then when you finish cooking the main in the oven, you can do the green beans.
