Using Kelp Powder in Recipes

There are endless ways to cook with nutrient-packed kelp powder:

Seasonings and Condiments

Kelp powder makes an easy addition to:

  • Homemade veggie broths and soups
  • Salad dressings
  • Sauces
  • Dips like hummus
  • Marinades for tofu, tempeh, veggies
  • Nutritional yeast seasoning blends
  • Furikake rice seasoning
  • Homemade vegan fish sauce

It adds salty, savory umami flavor to anything it seasons. A little goes a long way, so start with 1⁄4 to 1⁄2 teaspoon kelp powder at first.

Veggies, Grains and Legumes

Mix kelp powder into:

  • Fried rice or veggie stir-fries
  • Curries, chili, stews
  • Soups like miso soup, ramen, chowder
  • Steamed or roasted vegetables
  • Whole grains like rice, quinoa, farro
  • Lentils, bean salads, chickpeas

It enhances any savory dish with extra nutrients and rich flavor. Use 1⁄2 to 1 teaspoon per serving.

Plant-Based Seafood

Harness the ocean-like taste of kelp powder to make vegetarian seafood recipes like:

  • Tofu fish sticks or cakes
  • Lentil tuna salad sandwiches
  • Walnut shrimp or scallops
  • Kelp noodle salad
  • Vegan crab cakes
  • Clamless chowder

The briny flavor mimics real shellfish. Use up to 1 tablespoon kelp powder per recipe batch.

Smoothies and Juices

Add just a pinch (1⁄8 teaspoon) of kelp powder into:

  • Green smoothies
  • Fruit smoothies
  • Vegetable juices
  • Nut milks like almond milk

It blends in smoothly, adding extra iodine and minerals. Too much makes drinks taste fishy.

Key Takeaway: Kelp powder can season dishes, mimic seafood flavors, and boost nutrition in smoothies/juices. Use small amounts to avoid overwhelming fishiness.

Kelp Noodle Salad Recipe

Kelp noodles are a unique low-calorie, gluten-free noodle option made from sea kelp. Combined with vegetables and kelp powder dressing, this recipe makes for a nutrient-dense salad.


  • 1 (12 ounce) package kelp noodles
  • 1 English cucumber, julienned
  • 1 red bell pepper, sliced
  • 3 green onions, chopped
  • 1⁄4 cup kelp powder
  • 3 tablespoons lemon juice
  • 3 tablespoons olive oil
  • 2 cloves garlic, minced
  • 1 teaspoon ginger, minced


  1. Rinse kelp noodles well under water. Cut noodles into shorter strands for easier eating.
  2. Whisk together dressing ingredients (kelp powder through ginger).
  3. Mix cucumber, bell pepper, green onions and kelp noodles together.
  4. Pour dressing over noodle vegetable mixture and toss well to coat evenly.
  5. Chill for 30 minutes and serve cold.

Adding extra kelp powder along with the noodles really punches up the salty umami seafood flavors. Cucumber, bell pepper and green onions add freshness and crunch.

While kelp powder can be purchased, it's also easy to make at home with dried kelp sheets. DIY kelp powder allows you to control quality and save money.


  • Dried kelp sheets
  • Blender or food processor


  • Break kelp sheets into smaller pieces.
  • Process in a high-speed blender or food processor until a fine powder.
  • Use as you would store-bought kelp powder in recipes.


When making your own kelp powder, use a strong blender to ensure the seaweed is finely ground. Store in an airtight container away from light.

Storing Kelp Powder

To retain maximum freshness and nutritional value, store kelp powder properly:

  • Keep kelp powder in an airtight container in a cool, dark place. Light, heat and air exposure causes fading.
  • Glass jars or reusable food pouches work well for storage.
  • Avoid plastic bags which allow more air transfer.
  • Store homemade kelp powder in the freezer to prevent clumping if you live in humid environments.
  • Properly stored, kelp powder keeps for 6-12 months. If color fades or it smells fishy, it has expired.

Key Takeaway: Store kelp powder in an airtight, opaque container in a cool, dark place. It keeps for up to one year when stored properly.

Health Benefits of Kelp Powder

Kelp powder offers an array of vitamins, minerals and health promoting compounds:

  • Iodine - Kelp has the highest amount of bioavailable iodine in any food. Iodine supports thyroid and metabolic health. Those avoiding salt may be low.
  • Antioxidants - Contains antioxidant pigments like chlorophyll (green) and fucoxanthin (brown) that fight cell damage by neutralizing free radicals.
  • Fiber - High soluble and insoluble fiber aids digestion and gut health. Fiber also helps regulate cholesterol and blood sugar levels.
  • Iron - Rich source of plant-based iron to prevent deficiency. Iron carries oxygen in the blood to cells.
  • Minerals - Dense in magnesium, potassium, zinc, manganese and more minerals that boost bone, muscle, nerve and enzyme function.
  • Vitamin K - Excellent source of fat soluble vitamin K. Required for proper blood clotting.
