Kelp Powder Uses

Kelp powder is a versatile ingredient that can be used in a variety of dishes. Derived from dried kelp seaweed, this powder packs a nutritional punch and adds savory umami flavor to foods.

Kelp Powder Uses

So what are some of the best ways to use kelp powder in cooking and baking?

What Is Kelp Powder?

Kelp is a type of brown algae that grows in shallow, nutrient-rich saltwater. It's most often found in cool coastal climates like the Pacific Northwest and New England in the United States, as well as Northern Europe and East Asia.

Kelp has been used as a nutritional supplement and cuisine ingredient, especially in Asian cultures, for centuries. Today it's gaining popularity worldwide due to modern research that touts its health benefits.

To make kelp powder, mature kelp plants are harvested and sun-dried. The dried kelp leaves are then milled into a fine greenish-brown powder that has a mildly briny, ocean-like flavor.

Kelp powder is low in calories and fat but high in nutrients like iodine, potassium, iron, calcium and vitamin K. It also contains glutamic acids that provide savory umami flavor.

Here's a nutritional breakdown of kelp powder per 100 grams:

  • Calories: 248
  • Fat: 0.5g
  • Carbs: 49.5g
  • Protein: 7.9g
  • Fiber: 0g
  • Sodium: 3100mg

With its concentration of minerals and antioxidants, kelp powder supplementation may provide health benefits like:

  • Boosted thyroid function
  • Reduced inflammation
  • Lower blood pressure
  • Increased immunity
  • Improved digestion

Beyond being healthy, kelp powder is also sustainable and eco-friendly. Kelp absorbs carbon dioxide from the atmosphere, so harvesting it may help reduce ocean acidification. Plus, kelp can be grown and harvested year-round without the need for fresh water, fertilizers or feed like land crops require.

Using kelp powder is an easy way to get a nutrient boost while also helping the planet! The flavor pairs well with Asian cuisine in particular, but works in many types of savory dishes.

Seasoning Blends

One of the easiest ways to use kelp powder is as part of a versatile seasoning blend. Mix it with ingredients like sesame seeds, salt, pepper and red pepper flakes. Sprinkle the kelp blend on vegetables, eggs, meats, fish, grains and more to add flavor.

Some kelp powder seasoning mixes to try:

  • Toasted sesame seeds, kelp powder, salt, sugar, bonito flakes - sprinkle on rice, noodles or steamed veggies
  • Kelp powder, basil, savory, celery seed, sage, thyme, marjoram - use like salt to season soups, eggs and meat
  • Kelp powder, nutritional yeast, garlic powder, onion powder, salt, pepper - sprinkle on popcorn or roasted veggies

Key Takeaway: Make your own seasoning blends with kelp powder and other spices or dry ingredients. They're incredibly versatile options for turning up flavor in savory dishes.

Soups, Stews & Broths

Another fantastic way to enjoy the taste of kelp powder is in warm brothy dishes like soups, stews and broths. The kelp adds a hit of umami depth while infusing the dish with valuable nutrients.

Simply whisk a teaspoon or two of the powder into the pot as the soup simmers. Lentil, miso, vegetable, seafood stews are all nicely elevated with some kelp. An easy homemade dashi broth can be made with just water, kelp and bonito flakes too.

Some recipe ideas that pair beautifully with kelp powder:

  • Miso soup - Combine dashi stock, miso paste and kelp powder
  • Seafood stew - Simmer fish, shellfish, veggies and seasonings with kelp
  • Vegetable soup - Puree veggies with broth and kelp powder for flavor
  • Bean soup - Boost canned or cooked dried beans with kelp richness

Key Takeaway: Kelp powder makes a nutrient-packed addition to warm brothy dishes like soups, stews and homemade broths.

Salad Dressings & Dips

The briny flavor of kelp teams up deliciously with acidic and creamy ingredients like lemon juice, vinegar and olive oil. Take advantage of this by spiking your favorite salad dressing or dip recipes with kelp powder.

Simply add about 1/4 to 1/2 teaspoon kelp powder per batch of dressing or dip. Whisk vigorously so it incorporates well and doesn't get clumpy. Bottled dressings can also be jazzed up by adding a pinch of kelp powder right before serving and shaking or whisking to distribute it.

Some salad dressing and dip ideas perfect for experimenting with kelp powder:

  • Lemon-kelp vinaigrette
  • Kelp green goddess dressing

Noodle & Rice Bowls

In Asian cuisine, kelp is traditionally used to make dashi stock that flavors and fortifies noodle broths or rice porridge. You can bypass making dashi yourself by just sprinkling kelp powder straight onto finished noodle and rice-based dishes.

Toss the kelp powder with hot ramen, udon or soba noodles right before serving. Mix it into fried rice or bibimbap along with other seasonings like sesame oil and soy sauce. Stir some into congee or jook savory rice porridge too.

Fish & Seafood Dishes

It's only natural that dishes featuring fish and shellfish pair fabulously with the ocean-y essence of kelp. Sprinkle kelp powder over simply prepared seafood before serving. Or add it into the sauce, crust or stuffing you're cooking the fish or shellfish with.

Some recipes that complement kelp's briny flavor:

  • Broiled fish fillets or steaks with lemon-kelp drizzle
  • Shrimp scampi - add kelp to buttery wine sauce

Key Takeaway: Seafood servings like fish, shrimp and shellfish become supercharged with flavor and nutrition when enhanced with umami-rich kelp powder.

Meat & Poultry

While kelp powder shines in seafood preparations, its savory flavor can also ramp up meat and poultry dishes. Use it anywhere you'd normally use salt or other seasonings.

Stir kelp powder into ground meat mixtures for burgers or meatloaf. Combine it with breadcrumbs or flour when coating chicken, beef or pork cutlets before pan-frying. Rub kelp spice blends containing the powder onto roasts or chops before grilling or broiling.

Even a dash of the powder into the water when boiling eggs adds complementary flavor to simple hard boiled egg snacks.

  • Turkey or beef meatloaf or meatballs

My name is Sarah and I'm a baker who loves trying out new recipes and flavor combinations. I decided to challenge myself to use a new spice or ingredient powder in my baking each week for a year. Some successes were the cardamom sugar cookies, vivid turmeric cake, and beetroot chocolate cupcakes. Failures included the bitter neem brownies and overwhelmingly hot ghost pepper snickerdoodles. Through this experience I've discovered amazing additions to spice up desserts while learning how to balance strong flavors. Follow my journey as I push the boundaries of baking with unique powders!
