The beauty of this beginner kimchi is its flexibility. Here are the core ingredients and easy swaps so you can still make a delicious batch with what you have on hand.
Cucumbers: Kirby or Persian cucumbers are best for their crunch and few seeds. If you only have English cucumbers, they work too; just peel them if the skin is thick.
Gochugaru (Korean red pepper flakes): This gives authentic flavor and a mild heat. Use medium or fine grind. Substitute with crushed red pepper flakes (spicier) or paprika (milder).
Fish sauce: Adds savory umami. For a vegan version, swap with soy sauce or kelp powder.
Garlic and ginger: Freshly minced is best. They bring that pungent, aromatic kick.
Green onions (scallions): Use the whole scallion, chopped.
Sugar: Balances the heat. A teaspoon is usually enough.
Rice vinegar (optional): Adds a gentle tang if you like.

How Do I Ferment My Cucumber Kimchi Properly?
Fermenting cucumber kimchi is not complicated, but a few tricks make all the difference. Because cucumbers are mostly water, they can get mushy quickly if you’re not careful. Here’s how to do it right.
Press out air pockets: After mixing your seasoned cucumbers, pack them tightly into a clean jar. Use a spoon or your hand to press down so there are no big air gaps. This helps prevent spoilage.
Leave headspace: Fill the jar but leave about an inch of space at the top. As the kimchi ferments, it may produce a little liquid and expand slightly.
Taste daily: Leave the jar at room temperature (out of direct sunlight) for 1 to 2 days. Open the lid each day and taste a piece. When it reaches your desired level of tanginess, it’s time to move it to the fridge.
Refrigerate to stop fermentation: Once you like the flavor, pop the jar in the refrigerator. The cold slows down the fermentation, so the flavor continues to develop but at a much slower pace.
Tip: If you prefer a quick, non fermented version, skip the room temperature step and refrigerate immediately. It will be more like a spicy cucumber salad, still delicious and crunchy!
To keep your cucumbers crunchy, don’t over mix the paste; use a gentle tossing motion. Also, brining the cucumbers for 30 minutes draws out excess water, which helps them stay crisp.
FAQ: Easy Cucumber Kimchi Recipe
Can I use English cucumbers for kimchi?
Yes, English cucumbers work well. They have thin skin and few seeds, but they are less firm than Kirby or pickling cucumbers. For best crunch, remove some seeds and salt the slices briefly before mixing.
How do I keep cucumber kimchi crunchy?
Salt the cucumber slices and let them sit for 15 20 minutes, then rinse and squeeze gently. This draws out excess water. Also, use a firm cucumber variety like Kirby and avoid over fermenting. Refrigerate and eat within a few days for maximum crunch.
Do I need to ferment cucumber kimchi?
No, you can make a quick, non fermented version by mixing salted cucumbers with the seasoning paste and refrigerating. This is easier for beginners and still very flavorful. Fermented versions take 1 2 days at room temperature.
What is gochugaru and can I substitute it?
Gochugaru is Korean red chili pepper flakes with a mildly smoky, sweet heat. A good substitute is a mix of crushed red pepper flakes and a pinch of paprika, but flavor will differ. For best results, buy gochugaru at an Asian market or online.
How long does cucumber kimchi last in the fridge?
Quick cucumber kimchi lasts 3 5 days in an airtight container. Fermented versions keep 1 2 weeks, but cucumbers soften over time. For best texture, eat within a few days.
How can I make cucumber kimchi less spicy?
Reduce the amount of gochugaru to 1 teaspoon or omit it altogether. Add extra garlic, ginger, and sesame seeds for flavor. You can also mix in a little sugar to balance heat.
