Kale or Spinach: Which Green to Cook, Use & Store

Kale and spinach are two of the most versatile leafy greens, but they behave very differently in the kitchen. This guide breaks down exactly when to use each, how to cook them so they taste great, and how to store them so they last. Whether you’re sautéing, adding to soups, or making a salad, you’ll know which green to grab and how to handle it.

Ingredients

  • 1 bunch kale (about 12 oz / 340 g) or 10 oz (280 g) baby spinach
  • 2 tablespoons (30 ml) olive oil
  • 2 cloves garlic, thinly sliced
  • 1/4 teaspoon salt, plus more to taste
  • 1/4 teaspoon black pepper
  • 1 tablespoon (15 ml) lemon juice (optional)
  • 1/4 cup (25 g) grated Parmesan cheese (optional)

Instructions

  1. If using kale, wash the leaves and strip them from the tough stems. Tear or chop the leaves into bite-sized pieces. If using spinach, just rinse and drain well.
  2. Heat the olive oil in a large skillet over medium heat. Add the garlic and cook until fragrant, about 30 seconds, being careful not to brown it.
  3. Add the kale (or spinach) to the skillet. If using kale, add 2 tablespoons (30 ml) of water to help it steam. If using spinach, no water is needed—it will release its own.
  4. Cook, tossing occasionally, until the greens are wilted and tender. Kale will take about 5–7 minutes; spinach will take 2–3 minutes.
  5. Season with salt and pepper. If using, stir in the lemon juice and Parmesan. Serve warm.

Tips

  • Substitutions: For kale, you can use Swiss chard or collard greens—just adjust cooking time. For spinach, arugula or beet greens work but will cook faster.
  • Storage: Store unwashed greens in a plastic bag with a paper towel in the fridge. They’ll keep for 3–5 days. Wash just before using.
  • Common mistake: Overcooking spinach turns it mushy and watery. Cook it just until wilted, then remove from heat. For kale, not removing the stems makes it chewy—always strip them.
  • Flavor boost: Add a pinch of red pepper flakes or a splash of balsamic vinegar at the end for extra depth.

Serving Suggestions

Serve sautéed greens as a side dish with grilled chicken, fish, or tofu. They also make a great topping for pasta, polenta, or scrambled eggs. For a light meal, toss them with cooked quinoa and a drizzle of tahini.

Variations

  • Creamed spinach: After sautéing, stir in 1/2 cup (120 ml) heavy cream and simmer until thickened.
  • Garlicky kale with chili: Add 1/2 teaspoon red pepper flakes with the garlic for a spicy kick.
  • Asian-style: Use sesame oil instead of olive oil, add a splash of soy sauce and a sprinkle of sesame seeds.
  • Raw salads: For kale, massage with lemon juice and olive oil for 2 minutes to soften. Spinach is tender enough to use as-is.

Storage and Reheating

Refrigerate cooked greens in an airtight container for up to 4 days. Reheat in a skillet over medium heat until warmed through, or microwave in 30-second bursts. For best texture, add a tiny splash of water when reheating. Freeze cooked greens for up to 3 months—thaw overnight in the fridge before reheating.

Frequently Asked Questions

Can I eat kale and spinach raw? Yes, both are great raw in salads. However, kale is tougher and benefits from massaging with dressing for a few minutes to soften. Spinach is tender and can be used straight from the bag.

Which is more nutritious? Both are nutrient-dense. Kale is higher in vitamins A and C, while spinach has more iron and folate. Neither is “better”—vary your intake.

Do I need to remove kale stems? Yes, the stems are fibrous and chewy. Hold the leaf at the base and pull upward to strip the leaf from the stem, or use a knife to cut around the stem.

Can I substitute frozen spinach in cooked dishes? Yes, but thaw it first and squeeze out excess water to avoid a watery dish. Frozen spinach is already blanched, so add it near the end of cooking.

Why is my sautéed spinach watery? Spinach releases a lot of water. Cook it in batches over high heat, and don’t cover the pan—the steam will escape. Remove it as soon as it wilts.

How do I keep cooked greens from turning bitter? Overcooking can concentrate bitterness. Cook just until tender, and add a squeeze of lemon or a pinch of sugar to balance flavors.
