How to Cook Costco Edamame Easily

The fastest way to cook frozen edamame. Takes under 5 minutes and the bags are microwave-safe right out of the package.

Perfect for a quick protein snack or last-minute appetizer.

Step 1: How Do You Prepare the Edamame?

Almost no prep needed.

Instructions:

1. Remove one 8oz bag from the freezer
2. If using the steamable bag, leave it sealed with a small vent
3. If transferring to a bowl, add 1-2 tablespoons of water

Equipment: Microwave-safe bowl with lid (or use the steamable bag directly)

Step 2: What Power Level and Time Do You Use?

High power works best. The steam cooks the soybeans evenly.

Instructions:

1. Microwave on HIGH (100% power)
2. Cook for 2-3 minutes for a single serving
3. For a full 8oz bag, cook 4-5 minutes

Power Level: HIGH (100%)

Time: 2-5 minutes depending on quantity

Step 3: When Do You Check or Stir?

Stirring helps distribute heat evenly.

Instructions:

1. Pause at the halfway mark
2. Carefully open and stir the edamame
3. Resume cooking for remaining time

Checkpoint: At 2-minute mark for full bags

Step 4: How Do You Know When It’s Done?

The pods should be bright green and steaming.

Instructions:

1. Test one pod by squeezing it gently
2. The beans inside should pop out easily
3. They should be tender but not mushy

Visual Indicator: Bright green color, steam rising, beans pop out easily when squeezed

Method 2: Stovetop Boiling

Classic method for cooking larger batches. Simple and reliable.

Good option when you want to cook the entire 6lb package for meal prep or a party.

Step 1: How Do You Prepare the Water?

You need enough water to fully cover the edamame.

Instructions:

1. Fill a large pot with water
2. Add 1 teaspoon of salt per quart of water (optional)
3. Bring to a rolling boil

Equipment: Large pot, colander for draining

Step 2: What Temperature and Time Do You Use?

Boiling water cooks edamame quickly.

Instructions:

1. Add frozen edamame directly to boiling water
2. Return to a boil
3. Cook for 4-5 minutes

Temperature: Rolling boil (212°F)

Time: 4-5 minutes

3. Transfer to serving bowl
4. Sprinkle with sea salt while still warm

Checkpoint: Beans should be tender but firm

Step 4: How Do You Know When It’s Done?

Instructions:

1. Test one pod after 4 minutes
2. Squeeze to check if beans release easily
3. Cook 1 more minute if needed

Visual Indicator: Vibrant green color, pods slightly softened, beans pop out with light pressure

Method 3: Air Fryer

Produces a crispy, roasted texture different from traditional steamed edamame.

Takes longer but gives you that restaurant-style appetizer vibe. Great for snacking.

Step 1: How Do You Prepare the Edamame?

Frozen edamame works directly in the air fryer. No thawing needed.

Instructions:

1. Remove edamame from packaging
2. Pat dry with paper towel if there’s excess moisture
3. Toss with 1 teaspoon of oil (optional, helps with crispiness)
4. Season with salt, garlic powder, or your preferred seasoning

Equipment: Air fryer, mixing bowl, paper towels

Step 2: What Temperature and Time Do You Use?

Higher temperatures produce crispier results.

Instructions:

2. Spread edamame in a single layer in the basket
3. Cook for 8-12 minutes total

Temperature: 380-400°F

Time: 8-12 minutes

Step 3: When Do You Shake the Basket?

Shaking redistributes the pods for even cooking.

Instructions:

1. Shake the basket every 3-4 minutes
2. Check for browning at the 8-minute mark
3. Continue cooking if you want more crispiness

Checkpoint: Shake at 4-minute mark, then again at 8 minutes

Step 4: How Do You Know When It’s Done?

3. Add 2-3 more minutes for extra crispiness

Visual Indicator: Golden brown spots, slightly charred edges, crispy exterior

Method 4: Steaming

Steaming preserves the most nutrients and gives you the brightest green color.

Takes a bit longer than microwaving but produces superior texture.

Step 1: How Do You Set Up the Steamer?

Any steam basket setup works fine.

Instructions:

1. Add 1-2 inches of water to pot
2. Place steam basket inside (water should not touch the basket)
3. Bring water to a boil

Equipment: Pot with lid, steam basket or steamer insert

Step 2: What Time Do You Steam For?

Steaming takes slightly longer than boiling.

Instructions:

1. Add frozen edamame to steam basket
2. Cover with lid

Time: 5-7 minutes

Step 3: How Do You Know When It’s Done?
