Cooking Methods Comparison

Recommended Method: Air fryer for crispy texture in under 8 minutes without deep frying.

Method 1: Air Fryer (Recommended)

Air frying these frozen dumplings produces a crispy, golden exterior similar to restaurant-style wontons. Takes 6-8 minutes at 380F. Cook 10-15 wontons per batch.

Step 1: How Do You Prepare the Wontons?

No thawing required. Cook them straight from frozen for best results.

Instructions:

1. Remove desired amount of frozen wontons from bag
2. Spray lightly with cooking oil on both sides
3. Arrange in a single layer in the air fryer basket

Equipment: Air fryer, cooking spray (olive oil or vegetable oil)

Step 2: What Temperature and Time Do You Use?

Set your air fryer to 380F. Most models take 6-8 minutes, but check at the 6-minute mark.

Instructions:

1. Preheat air fryer to 380F for 3 minutes
2. Cook for 6-8 minutes total

Temperature: 380F (some recipes suggest 360-400F depending on your model)

Time: 6-8 minutes

Step 3: When Do You Shake or Flip?

Shake the basket or flip wontons at the halfway point. This gets both sides crispy and prevents sticking.

Instructions:

1. At 3-4 minutes, pull out the basket
2. Shake or use tongs to flip each wonton

Checkpoint: At 3-4 minute mark

Step 4: How Do You Know When They’re Done?

Look for golden brown color and crispy edges. The wrapper should feel firm when tapped.

Instructions:

1. Check color at 6 minutes
2. Add 1-2 minutes if not golden enough
3. Remove when edges are crispy

Visual Indicator: Golden brown exterior, crispy to the touch

Method 2: Pan Fry

Pan frying creates a crispy bottom with a slightly softer top. Takes about 5 minutes on medium heat. Great if you don’t have an air fryer.

Step 1: How Do You Prepare the Pan?

Use a nonstick frying pan and enough oil to coat the bottom. Don’t overcrowd.

Instructions:

1. Add vegetable oil to cover the bottom of a nonstick pan
2. Heat on medium until oil shimmers

Equipment: Nonstick pan, vegetable oil, spatula

Step 2: What Temperature and Time Do You Use?

Medium heat works best. High heat burns the outside before the inside warms through.

Instructions:

1. Add 10-12 frozen wontons to the heated oil
2. Cook for 5-7 minutes total

Temperature: Medium heat (setting 5 out of 10)

Time: 5-7 minutes

Step 3: When Do You Flip?

Once the bottoms turn golden brown, flip to crisp the other side. Usually around the 3-minute mark.

Instructions:

1. Check bottom color at 3 minutes
2. Flip when golden brown appears

Checkpoint: At 3 minute mark

Step 4: How Do You Know When They’re Done?

Both sides should be golden brown with some char marks. Steam should rise when you cut one open.

Visual Indicator: Golden brown on both sides, steaming when pierced

Method 3: Microwave

The fastest option at just 1-2 minutes. Texture is soft and steamed rather than crispy. Perfect for a quick lunch or when you’re in a rush.

Step 1: How Do You Prepare for Microwave?

Wet paper towels are the key here. They create steam and prevent the wrapper from drying out.

Instructions:

1. Place a wet paper towel on a microwave-safe plate
2. Arrange 10-12 frozen wontons in a single layer
3. Cover with another wet paper towel

Equipment: Microwave-safe plate, paper towels

Step 2: What Power Level and Time?

High power for 1-2 minutes. Start with 1 minute and add time if needed.

Instructions:

1. Microwave on HIGH for 1-2 minutes
2. Check if hot throughout

Power Level: HIGH (100%)

Time: 1-2 minutes

Step 3: How Do You Know When They’re Done?

The wrapper should look slightly translucent and the filling should be steaming hot.

Visual Indicator: Wrapper appears slightly translucent, steam rising

Method 4: Wonton Soup / Boil

Adding these to broth or boiling water takes 1-2 minutes. The filling heats through while the wrapper stays tender.

Step 1: How Do You Prepare the Broth?

Use chicken broth, vegetable broth, or plain boiling water.

Instructions:

1. Bring 4-6 cups of broth or water to a boil
2. Reduce to a gentle simmer

Equipment: Pot, slotted spoon

Step 2: How Long Do You Cook Them?

Just 1-2 minutes in boiling liquid. Don’t overcook or the wrapper gets mushy.

Instructions:

1. Add 10-12 frozen wontons to simmering broth
2. Cook for 1-2 minutes
3. Remove with slotted spoon or serve in soup

Time: 1-2 minutes

Step 3: Serving Suggestions for Soup

For a complete wonton soup, add bok choy, green onion, and a drizzle of sesame oil. Ramen or udon noodles turn it into a full meal. If you’re making an Asian-inspired dinner, pair with Costco fried rice or Costco egg rolls.

Troubleshooting Common Issues

Issue: Wontons are soggy, not crispy

Cause: Overcrowding in air fryer basket or not using oil spray

Solution: Arrange in single layer without overlapping. Always spray with cooking oil before air frying.

Issue: Wontons stick to air fryer basket

Cause: No oil on the basket or wontons

Solution: Spray basket and wontons with cooking spray. Use parchment paper with holes designed for air fryers.

Issue: Uneven cooking (some crispy, some soft)

Cause: Forgot to flip or shake halfway through

Solution: Set a timer for the halfway point. Shake basket or flip each wonton with tongs.

Issue: Wrapper burned but filling cold

Cause: Temperature too high

Solution: Lower temperature to 360-380F. All air fryer models run slightly different.

FAQ on How To Cook Costco Wontons

How Long Do You Cook Costco Wontons in an Air Fryer?

Cook frozen Bibigo mini wontons at 380F for 6-8 minutes in your air fryer.

Shake the basket halfway through. Check at 6 minutes. Add time if you want them crispier.

No preheating required for most models.

Do You Need to Thaw Bibigo Wontons Before Cooking?

No. Cook them straight from frozen.

Thawing actually makes the wonton wrapper soggy and causes sticking. The frozen dumplings crisp up better when they go directly into heat.

This applies to all cooking methods.

What Temperature Should I Air Fry Frozen Wontons?

Most recipes recommend 380F, though some air fryer models work better at 360-400F.

Start at 380F. If your wontons burn before cooking through, lower to 360F next time.

Can You Microwave Costco Mini Wontons?

Yes. Place 10-12 frozen wontons on a plate lined with a wet paper towel. Cover with another wet towel.

Microwave on HIGH for 1-2 minutes. The texture is soft rather than crispy.

How Do You Make Costco Wontons Crispy?

Air frying or pan frying gives the crispiest results.

Spray wontons with cooking oil before air frying. For pan frying, use enough vegetable oil to coat the bottom of a nonstick pan. Cook until golden brown.

What Dipping Sauce Goes With Bibigo Wontons?

These chicken wontons pair well with soy sauce, sweet chili sauce, or chili crisp.

Mix soy sauce with rice vinegar and sesame oil for a classic dipping sauce. Sriracha adds heat if you want it.

How Many Wontons Are in a Costco Bag?

The 3-pound bag contains approximately 150 mini wontons.

A serving is 4 pieces at 50 calories. Most people eat 8-13 wontons per sitting. That gives you roughly 10-12 full servings per bag.

Can You Boil Costco Wontons for Soup?

Absolutely. Add frozen wontons to boiling chicken or vegetable broth for 1-2 minutes.

Toss in bok choy and green onion. Drizzle with sesame oil. Add Costco udon noodles for a heartier meal.

Are Bibigo Mini Wontons Already Cooked?

Yes. These are fully cooked frozen wontons made by CJ Foods.

You’re just reheating them. That’s why cooking times are so short. No food safety concerns about undercooked chicken here.

How Do You Store Leftover Cooked Wontons?

Refrigerate in an airtight container within 2 hours. Eat within 3-4 days.

Reheat in the air fryer at 350F for 2-3 minutes. Don’t refreeze cooked wontons. The texture suffers.

Conclusion

Now you know how to cook Costco wontons using four different methods. The air fryer delivers the crispiest results at 380F in under 8 minutes.

Pan frying works great for golden brown bottoms. Microwave when speed matters most.

For wonton soup, just drop the frozen Bibigo dumplings into simmering broth for 1-2 minutes.

Pair these bite-sized appetizers with soy sauce, chili crisp, or sweet chili for dipping.

At roughly 7 cents per wonton, this CJ Foods product is solid for meal prep, party trays, or quick dinners.
