Roasted Green Beans and Potatoes are a delectable and convenient way to serve two side dishes in one. Whether you’re preparing them for a holiday meal or tossing them together for a simple weeknight dinner, you’ll need just 5 simple ingredients and 10 minutes of active time. A simple technique ensures that both vegetables are cooked just right and ready to serve at the same time.

Roasted Green Beans and Potatoes

It might seem daunting to achieve crispy potatoes that are creamy within and tender, caramelized green beans when they’re roasted together at the same temperature. But it’s all about placement and time. Arranging each vegetable on one side of a baking sheet allows you to control the roasting times individually so that both are cooked to perfection.

Ingredients for Roasted Green Beans and Potatoes

  • Green Beans: small, thin French green beans (haricot verts) are best for this recipe
  • Potatoes: ideally Yukon Gold potatoes or other waxy or semi-waxy potatoes like fingerling potatoes or baby potatoes
  • Olive Oil: good quality extra-virgin olive oil
  • Garlic: fresh garlic cloves
  • Fresh Rosemary: or fresh thyme leaves
  • Kosher Salt and Freshly Ground Black Pepper

Seasoning this dish simply with good olive oil and fresh rosemary and garlic enhances the natural flavors and textures of the vegetables instead of overpowering them.

Why Fresh Aromatics are Best

Instead of dried or powdered spices, it’s best to use fresh garlic and rosemary in this dish. Because of the short list of ingredients, each one has the chance to shine. Finely mincing the two aromatics helps them evenly distribute throughout the vegetables.

That said, granulated garlic and a dried herb blend like Italian seasoning are fine substitutions for fresh herbs if that’s what you have on hand.

Key Steps

Partially cooking each vegetable separately is the first key step to ensuring that they cook properly during the roasting process. While the potatoes start roasting, the green beans get a quick steam to help them maintain their vibrant green color. Once the potatoes are a little over halfway cooked, the steamed green beans are added to soften and caramelize.

Keeping the vegetables on separate halves of the baking sheet is the second key step. This way it’s easy to adjust timing if one or the other needs a few more minutes. When the final timer goes off, you should have two beautifully roasted vegetables ready to serve.

How to Store and Reheat

Store in the refrigerator in an airtight container for up to 5 days. To reheat: heat a generous drizzle of olive oil in a large nonstick skillet over medium heat. Add leftover vegetables and cook, gently stirring until heated through.

How to Make Roasted Green Beans and Potatoes

Toss potatoes with olive oil, rosemary, salt and pepper in a large bowl. Spread on one half of a parchment lined baking sheet and bake 25 minutes, stirring once, in an oven preheated to 425°F.

While the potatoes roast, steam green beans until just bright green. Transfer to a bowl and toss with olive oil, garlic, salt and pepper.

Stir partially roasted potatoes and spread lightly steamed green beans on the baking sheet’s opposite half. Bake until potatoes are crispy and green beans lightly caramelized. Combine vegetables and season to taste; transfer to serving bowl and serve hot.

    What a great idea to combine these together into one side dish! We’ve been hunting for interesting side dishes lately, and roasted green beans sounds fantastic. We usually prepare them in a skillet, but I’ve gotten a bit tired of the same old method. Great recipe!
