Although kale is available year-round, it's typically sweetest from midwinter through spring. Related to broccoli and cauliflower, kale is loaded with many of the same cancer-fighting phytochemicals. Potatoes offer complex carbohydrates and generous doses of potassium, iron, and vitamin B6. Leave the skin on for extra fiber.

Recipe Summary



Ingredient Checklist


Instructions Checklist
  • Preheat oven to 450 degrees. Combine potatoes, onion slices, 1 tablespoon oil, and 3/4 teaspoon salt on a rimmed baking sheet. Season with pepper, and toss. Spread mixture in a single layer (use a second sheet if necessary). Roast, stirring potatoes and scraping bottom of sheet about every 10 minutes, flipping halfway through, until potatoes are brown and crisp, 40 to 45 minutes.

  • Combine mustard and lemon zest and juice in a bowl. Heat remaining 2 teaspoons oil in a large straight-sided skillet over medium-high heat. Add garlic, and cook, stirring constantly, until golden brown, about 2 minutes. Add kale, and cook, stirring occasionally, until wilted, about 6 minutes. Add mustard-lemon mixture; toss to coat. Cook until heated through. Sprinkle with 1/4 teaspoon salt, and season with pepper. Toss with potatoes.
