Kale greens shrink dramatically when cooked, so plan for more than you think. If you’re wondering how to cook kale greens, you’ve come to the right place. This leafy green can be tough and bitter raw, but with the right techniques, it turns tender, flavorful, and downright delicious. Whether you’re a beginner or a seasoned cook, this guide covers everything from washing to seasoning.
Kale is packed with vitamins A, C, and K, plus fiber and antioxidants. But let’s be honest—eating a raw kale salad isn’t for everyone. Cooking mellows the bitterness and softens the leaves. Plus, it makes the nutrients easier to absorb. So let’s get started.
Why Cook Kale Greens?
Raw kale can be chewy and hard to digest. Cooking breaks down the tough cell walls, making it gentler on your stomach. It also reduces the oxalates, which can interfere with mineral absorption. The flavor changes too—from grassy and sharp to nutty and sweet.
Another reason? Volume. One bunch of kale might look huge, but after cooking, you’ll get about one cup. That’s why you need to start with more than you think. A 12-ounce bag of pre-chopped kale yields roughly 1.5 cups cooked.
Best Cooking Methods For Kale
There are several ways to cook kale, each giving a different texture and taste. Here are the most popular methods:
- Sautéing: Quick and easy, perfect for weeknights.
- Steaming: Retains nutrients and keeps kale tender.
- Boiling: Good for soups and stews, but loses some nutrients.
- Roasting: Turns kale crispy like chips.
- Braising: Slow-cooked with liquid for deep flavor.
Each method works well, but sautéing is the fastest and most versatile. Let’s dive into the step-by-step process.
How To Cook Kale Greens
Step 1: Choose The Right Kale
Not all kale is the same. Curly kale is the most common—it’s sturdy and holds up well to cooking. Lacinato kale (also called dinosaur kale) is flatter and slightly sweeter. Red Russian kale is more tender and has a milder flavor.
For cooking, curly kale is a great choice because it doesn’t turn mushy. But any variety works. Just make sure the leaves are dark green and crisp, not wilted or yellow.
Step 2: Wash Thoroughly
Kale grows close to the ground, so it can have dirt and grit. Fill a large bowl with cold water and submerge the leaves. Swish them around, then let them sit for a minute. Lift the kale out, leaving the dirt behind. Repeat if needed.
Dry the leaves with a salad spinner or pat them with a clean towel. Wet kale will steam instead of sauté, so dry it well for best results.
Step 3: Remove The Stems
The stems are tough and fibrous. Hold a leaf by the stem, then run your fingers down the length to strip the leaves off. You can also fold the leaf in half and cut the stem out with a knife.
Don’t throw the stems away—they’re edible! Chop them finely and cook them first, or save them for stock. But for tender kale, remove them.
Step 4: Chop The Leaves
Stack the leaves and slice them into ribbons or bite-sized pieces. Smaller pieces cook faster and are easier to eat. Aim for 1-inch wide strips. If you’re using pre-chopped kale, skip this step.
Step 5: Cook Using Your Preferred Method
Here are detailed instructions for each method:
Sautéed Kale
- Heat a large skillet over medium-high heat. Add 1-2 tablespoons of olive oil or butter.
- Add aromatics like garlic, onion, or red pepper flakes. Cook for 30 seconds until fragrant.
- Add the kale in batches if needed. It will wilt quickly.
- Toss with tongs to coat the leaves in oil. Cook for 3-5 minutes until tender.
- Season with salt, pepper, and a squeeze of lemon juice. Serve immediately.
Tip: Add a splash of water or broth to create steam if the kale looks dry. This helps it cook faster.
Steamed Kale
- Place a steamer basket in a pot with 1 inch of water. Bring to a boil.
- Add the kale and cover. Steam for 5-7 minutes until tender.
- Drain and season with salt, olive oil, and vinegar.
Steaming preserves more nutrients than boiling. It’s also hands-off and foolproof.
Boiled Kale
- Bring a large pot of salted water to a boil.
- Add the kale and cook for 3-5 minutes until tender.
- Drain and squeeze out excess water. Season as desired.
Boiling leaches some vitamins into the water, but it’s great for soups. Use the cooking liquid as a broth base.
Roasted Kale Chips
- Preheat oven to 350°F (175°C).
- Toss dry kale pieces with olive oil and salt. Spread in a single layer on a baking sheet.
- Bake for 10-15 minutes, flipping halfway. Watch closely—they burn fast.
- Cool for a few minutes before eating. They crisp up as they cool.
Roasted kale chips are a healthy snack. But they don’t keep well, so eat them the same day.
Braised Kale
- Heat oil in a Dutch oven over medium heat. Cook onion and garlic until soft.
- Add the kale and stir until wilted.
- Pour in 1/2 cup of broth, wine, or water. Cover and reduce heat to low.
- Cook for 20-30 minutes until very tender. Season with salt, pepper, and a splash of vinegar.
Braising makes kale silky and rich. It’s perfect for winter meals or as a side dish.
Step 6: Season And Serve
Kale pairs well with bold flavors. Try these combinations:
- Garlic and lemon
- Soy sauce and sesame oil
- Bacon and red pepper flakes
- Balsamic vinegar and Parmesan
- Coconut milk and curry spices
Add salt early to help break down the leaves. Acid like lemon or vinegar brightens the flavor. Don’t overseason—kale has a strong taste on its own.
Common Mistakes When Cooking Kale
Even experienced cooks make errors. Here’s what to avoid:
- Not drying the kale: Wet leaves steam instead of sauté, leading to soggy results.
- Overcooking: Kale can go from tender to mushy quickly. Keep an eye on it.
- Underseasoning: Kale needs salt and fat to taste good. Don’t be shy.
- Using too much heat: High heat can burn the leaves before they cook through. Medium-high is ideal.
- Skipping the stems: They’re tough and chewy. Remove them for better texture.
Another common mistake is not cooking enough. Remember, kale shrinks a lot. A full bunch might serve only two people as a side dish.
How To Store Cooked Kale
Cooked kale keeps well in the fridge for 3-5 days. Let it cool completely, then store in an airtight container. Reheat in a skillet or microwave. Add a splash of water if it seems dry.
You can also freeze cooked kale. Portion it into freezer bags and press out the air. It will keep for up to 3 months. Thaw in the fridge overnight and reheat. Frozen kale works best in soups and stews.
Nutritional Benefits Of Cooked Kale
Cooking kale makes its nutrients more bioavailable. For example, beta-carotene (vitamin A) is easier to absorb after cooking. The fiber stays intact, aiding digestion. And the calcium becomes more accessible when the oxalates are reduced.
One cup of cooked kale has about:
- 36 calories
- 5 grams of fiber
- 3 grams of protein
- 206% of your daily vitamin A
- 134% of vitamin C
- 684% of vitamin K
It’s also a good source of manganese, copper, and B vitamins. Adding a little fat (like olive oil) helps absorb the fat-soluble vitamins.
