Ingredients

- Green beans: Green beans adds a fresh, slightly crisp texture and vibrant color. These are rich in vitamins and fiber, making this dish both nutritious and delicious.
- Baby potatoes: These potatoes roast to a perfect golden brown, offering a creamy, hearty bite. They’re a great way to use up leftovers or the last of a potato bag.
- Olive oil: Ensures the vegetables roast evenly while adding a subtle richness.
- Garlic: Brings a punch of flavor and depth to the dish.
How to Make Leftover Roasted Potatoes and Green Beans
In a large bowl, combine the green beans and halved potatoes.

Drizzle with olive oil, then add minced garlic, thyme, rosemary, salt, and pepper. Toss until the vegetables are evenly coated.

Spread the vegetables in a single layer on a baking sheet.

Roast in the preheated oven for 30-35 minutes, stirring halfway through, until the potatoes are golden and tender, and the green beans are slightly crispy.

For a special touch, sprinkle some grated Parmesan cheese or a drizzle of balsamic glaze on top before serving.
