Home Fries With Red, White, and Green Onions

Original recipe came from the Williams-Sonoma Potato book. I made some adjustments.

• Ready In: 1 hr 30 mins
• Serves: 4

Ingredients

• 1 1⁄2 lbs yukon gold potatoes
• 2  tablespoons butter
• 1  tablespoon olive oil
• 1  cup red onion, diced
• 1  cup  white onion, diced
• 1  teaspoon salt
• 1⁄2 teaspoon ground pepper
• 1  cup green onion, chopped

Directions

1. Steam the unpeeled whole potatoes until tender when pierced with a fork. Let them cool, and refrigerate them until cold, at least 2 hours or up to 1 day. Peel the potatoes and cut into 1/2-inch cubes.
2. In a large, heavy nonstick frying pan, melt 1 tablespoon of the butter with the oil over medium-high heat. Add the potatoes, red onion, and white onion and toss to coat. Saute, tossing every 3 or 4 minutes, until the potatoes are light brown and the onions are just beginning to brown, about 15 minutes total.
3. Sprinkle with 1 teaspoon salt and 1/2 teaspoon pepper. Toss to blend.
4. Cook until the potatoes and onions are golden brown, about 5 minutes longer.
5. Add the green onions and remaining 1 tablespoon butter. Toss until the butter melts and the green onions just wilt, about 1 minute.
