Ingredients

• 500 grams baby potatoes
• 4 tablespoons olive oil
• 2 teaspoons fresh rosemary
• 1.5 teaspoons kosher salt
• 1 teaspoon black pepper
• 300 grams green beans
• 1 medium red onion
• 3 tablespoons red wine vinegar
• 1 teaspoon whole-grain mustard
• 1 teaspoon honey
• 1 clove garlic
• 2 tablespoons parsley (optional, for garnish)

Directions

Step 1

Preheat your oven to 200°C (400°F) and line a baking sheet with parchment paper.

Step 2

Wash the baby potatoes and cut them into bite-sized pieces. In a large mixing bowl, toss the potatoes with 2 tablespoons of olive oil, 1 teaspoon of rosemary, 1 teaspoon of kosher salt, and 0.5 teaspoon of black pepper.

Step 3

Spread the seasoned potatoes in an even layer on the prepared baking sheet and roast them in the oven for 25-30 minutes, tossing halfway through, until they are golden and crispy.

Step 4

While the potatoes are roasting, trim the ends of the green beans and blanch them in boiling salted water for 2-3 minutes until they are tender-crisp. Immediately transfer them to an ice bath to stop cooking, then drain and set aside.

Step 5

Peel and thinly slice the red onion. Heat 1 tablespoon of olive oil in a skillet over medium heat and sauté the onions with a pinch of salt until caramelized, about 8-10 minutes. Set aside.

Step 6

In a small mixing bowl, whisk together the remaining 2 tablespoons of olive oil, red wine vinegar, whole-grain mustard, honey, minced garlic, 1 teaspoon of rosemary, 0.5 teaspoon of kosher salt, and 0.5 teaspoon of black pepper to make the vinaigrette.

Step 7

In a large salad bowl, combine the roasted potatoes, green beans, and caramelized onions. Drizzle the rosemary vinaigrette over the top and gently toss to combine.

Step 8

Taste and adjust seasonings if needed. Garnish with fresh parsley (optional) before serving.
