Ingredients for Instant Pot Kimchi
Traditional Korean flavors meet modern convenience with these carefully selected components for authentic fermentation.
| Ingredient | Amount | Notes |
|---|---|---|
| Napa Cabbage 🥬 | 2 lb | Cored and cut into 2-inch pieces |
| Kosher Salt 🧂 | ½ cup | Diamond Crystal preferred for texture |
| Korean Red Pepper Flakes 🌶️ | ¾ cup | Gochugaru for authentic heat |
| Garlic Cloves 🧄 | 8 cloves | Peeled and minced finely |
| Fresh Ginger 🌿 | 2 tbsp | Peeled and grated |
| Scallions 🧅 | 8 whole | Cut into 2-inch pieces |
| Korean Radish 🥕 | 8 oz | Peeled and julienned |
| Fish-Free Soy Sauce 🫒 | ¼ cup | Use tamari for gluten-free option |
| Rice Flour 🌾 | 2 tbsp | For thickening the paste |
| Sugar 🍚 | 2 tbsp | Organic granulated preferred |
| Vegan Fish Sauce 🫒 | 2 tbsp | Substitute with soy sauce if unavailable |
| Carrots 🥕 | 2 whole | Peeled and julienned |
| Water 💧 | 1 cup | For rinsing cabbage |
The napa cabbage must be fresh and crisp—look for heavy heads with tight leaves at Asian markets or well-stocked grocery stores. Korean red pepper flakes (gochugaru) are essential and available at H Mart or online retailers. Avoid pre-shredded cabbage; the texture suffers. For best results, use Diamond Crystal kosher salt as its coarse grains dissolve evenly during brining.
No gochugaru? Crushed red pepper plus a pinch of paprika approximates the flavor, but authenticity may suffer. For fish-free soy sauce, tamari is the best gluten-free substitute. Vegan fish sauce can be replaced with additional soy sauce and a dash of seaweed flakes. The rice flour thickens the paste—cornstarch works in a pinch but may alter the texture slightly.
Store unopened gochugaru in a cool, dark place for up to 1 year. Once opened, keep it sealed tightly and use within 6 months. Fermented kimchi stays fresh in the fridge for 1-2 weeks in a sealed container. The flavor deepens over time, so taste as it ages.

Step-by-Step Instructions for Instant Pot Kimchi
This streamlined method delivers authentic flavor with the convenience of your pressure cooker.
Step 1: Salt and Rinse the Napa Cabbage
Cut the 2 lb Napa Cabbage into 2-inch pieces and place it in a large bowl. Sprinkle the 0.5 cup Kosher Salt evenly over the cabbage, massaging it between the leaves to ensure full coverage. Add the 1 cup Water and toss to distribute the salt evenly.
Let the cabbage sit for 1-2 hours, turning occasionally, until the leaves wilt and release liquid. Rinse thoroughly under cold water 3 times to remove excess salt, then drain well in a colander. Squeeze out as much water as possible—this prevents a watery final product.
Step 2: Prepare the Kimchi Paste
In a medium bowl, combine the 0.75 cup Korean Red Pepper Flakes, minced 8 cloves Garlic Cloves, grated 2 tbsp Fresh Ginger, 2 tbsp Sugar, 2 tbsp Rice Flour, 0.25 cup Fish-Free Soy Sauce, and 2 tbsp Vegan Fish Sauce. Stir until a thick, vibrant paste forms.
The rice flour acts as a binder, while the sugar balances the heat of the gochugaru. I mix this paste 10-15 minutes before using it to allow the flavors to meld. The consistency should resemble a spreadable chili sauce—thick but not dry.
Step 3: Combine Vegetables and Paste
In a large bowl, add the drained cabbage, 8 whole Scallions cut into 2-inch pieces, julienned 8 oz Korean Radish, and julienned 2 whole Carrots. Pour the kimchi paste over the vegetables and wear gloves to mix thoroughly, ensuring every piece is evenly coated.
Work the paste into the crevices of the cabbage leaves and between the layers. The vegetables should glisten with the red paste, and there should be no dry spots. This step is crucial for even fermentation and flavor distribution throughout the batch.
Step 4: Ferment in the Instant Pot
Transfer the kimchi mixture to your Instant Pot, pressing down gently to fit. Secure the lid and set the valve to Venting. Use the Yogurt function on Low for 8-12 hours, checking at the 8-hour mark for your preferred tanginess.
The Instant Pot maintains a consistent 110-115°F, ideal for rapid fermentation. You’ll notice bubbles forming and a tangy aroma developing—this signals the fermentation is active. The longer it ferments, the sourer it becomes, so taste periodically to achieve your desired flavor profile.
Pro Tips For Making Instant Pot Kimchi
- Salt the Cabbage First: I learned this the hard way—toss your quartered Napa cabbage with kosher salt and let it sit for 1-2 hours before mixing in other ingredients. It draws out excess water so your kimchi stays crisp, not soggy.
- Use Fine Gochugaru: Sounds weird, but it works: pulse your Korean red pepper flakes in a spice grinder for 5 seconds. The finer texture clings better to the cabbage and distributes flavor evenly.
- Skip Overpacking: Resist the urge to stuff your Instant Pot to the brim—fill it no more than halfway. Kimchi expands as it ferments, and I’ve had to clean up overflow more times than I’d like to admit.
- Add Ginger Last: Grate your fresh ginger just before mixing it in, not 30 minutes early. It keeps the flavor bright and sharp instead of letting it mellow out while you prep the rest.
Regional Styles of These Flavors
Northern Korean Style
This version uses more radish and less cabbage, with a watery consistency. I add 1 cup extra Korean radish and reduce the cabbage by ½ lb. The brine includes 1 tbsp apple juice for subtle sweetness. 🗺️
Southern Korean Style
Here, kimchi is saltier and spicier. I increase the gochugaru to 1 cup and add 1 tbsp extra salt. The fermentation time is shorter, around 6 hours in the Instant Pot, to preserve the crisp texture.
Vegan Fusion Style
For a modern twist, I swap the fish-free soy sauce with coconut aminos and add 1 tbsp miso paste to the kimchi paste. This creates a deeper umami flavor while keeping it vegan.
Quick Ferment Style
When I’m short on time, I use the Instant Pot’s High Pressure setting for 30 minutes. This speeds up fermentation significantly, but the texture may soften slightly. The flavor is still tangy and delicious.
Traditional Pogi Style
This version focuses on whole cabbage leaves. I use 1 large napa cabbage (about 3 lbs), leaving the leaves intact. The paste is stuffed between the leaves, and it ferments for 10 hours. 💛
Spicy Extra Kick
For heat lovers, I add 1 tbsp extra gochugaru and 1 tsp cayenne pepper to the paste. The Instant Pot helps distribute the heat evenly, ensuring every bite has a consistent spicy flavor.
Nutrition Facts
Frequently Asked Questions
Can I use regular cabbage instead of napa?
Regular green cabbage works but produces a crunchier texture. Use 2 lb and reduce salting time to 45 minutes as it softens faster than napa.
Why does my kimchi taste bland?
Under-fermentation is the most common cause. Extend the Yogurt setting to 12 hours or add an extra 1 tbsp sugar to boost flavor development.
How do I store leftover kimchi?
Transfer to an airtight container and refrigerate. It continues fermenting slowly, so consume within 2 weeks for best flavor and texture.
Is the Instant Pot method faster than traditional?
Yes! Traditional fermentation takes 1-5 days at room temperature. The Instant Pot’s controlled 110-115°F environment produces similar results in just 8-12 hours.
