Cooking Techniques and Times
Kale generally requires less cooking time than collard greens. When steaming, cook kale for 5-7 minutes instead of the 8-10 minutes typically needed for collards.
For sautéing, kale cooks in 5-8 minutes, while collards may take 10-15 minutes. Stir-frying kale takes about 3-5 minutes, compared to 5-7 minutes for collards.
When boiling, kale needs only 5-10 minutes, whereas collards usually require 15-20 minutes. For soups and stews, add kale later in the cooking process to prevent overcooking.
Roasting kale creates crispy chips in just 10-15 minutes at 350°F (175°C). This method isn’t typically used for collards but works well with kale’s texture.
Substituting Kale for Collard Greens
Kale can be an excellent substitute for collard greens in many recipes. Its similar nutritional profile and versatile nature make it adaptable to various dishes.
In Salads and Raw Dishes
Kale works well as a substitute for collard greens in salads and raw preparations. When using kale raw, massage it with a bit of olive oil and salt to soften the leaves and reduce bitterness. This technique mimics the tenderness of collard greens.
For a crisp texture similar to collards, choose Lacinato or dinosaur kale. Its flat leaves are easier to chop into thin strips for salads. Baby kale can replace collards in recipes calling for young, tender greens.
Consider these alternatives if kale isn’t available:
- Baby spinach
- Arugula
- Watercress
These options provide a fresh, slightly peppery flavor that complements many salad combinations.
In Soups, Stews, and Southern Cuisine
Kale can replace collard greens in cooked dishes like soups, stews, and traditional Southern recipes. Curly kale holds up well during long cooking times, making it ideal for these applications.
When substituting kale in Southern cuisine:
- Add kale later in the cooking process than you would collards
- Use slightly less cooking liquid, as kale releases less water
- Increase cooking time by 5-10 minutes for tougher kale varieties
To enhance kale’s flavor profile:
- Add smoked meats like bacon or ham hock
- Use chicken or vegetable broth instead of water
- Season with garlic, onion, and red pepper flakes
These adjustments help kale mimic the rich, savory taste of collard greens in traditional Southern dishes.
Alternative Leafy Greens and Substitutes
Several nutritious leafy greens can stand in for collard greens or kale in recipes. These alternatives offer similar textures and flavors while providing comparable nutritional benefits.
