Ingredients

Everyday kitchen measurements
For 2 servings. Use a small 180 ml paper cup, a level eating spoon (about 15 ml) and a small teaspoon (about 5 ml).
How to fill the cup and spoons
Use the same cup and spoons throughout. Their sizes vary, so these amounts are approximate. Spoon flour in loosely and level the top without pressing. Measure vegetables after chopping, without packing them down. The amounts in g/ml are the original reference quantities. For part of a pack, use the specified pack weight and divide the contents evenly.

- Use instead
- Unsweetened oat drink
- Substitute quantity
- 1 small paper cupReference quantity: 180 ml
If milk is unavailable, use this amount of plain unsweetened oat drink. It may taste slightly sweeter or thicken differently; keep the heat gentle. Butter still contains milk unless you also use its listed oil replacement. Check the drink label for allergens; do not use a sweetened or flavored drink.

Substitute available
If Korean doenjang soybean paste is unavailable
- Use instead
- Mild miso soybean paste
- Substitute quantity
- 1 level tablespoonReference quantity: 18 g
If doenjang is unavailable, use this amount of mild miso. Dissolve it in warm soup before adding, at the same final step. The flavor is milder and this version loses some distinctly Korean doenjang character. It still contains soy; check the label for wheat. Do not add both pastes.

Step 1

Choose firm potatoes without green patches. Wash and peel 2 medium potatoes, about 300 g, then cut into even 1.5 cm cubes. Peel and finely chop half an onion and 2 garlic cloves. Set aside the milk and doenjang; do not add them yet.
-
Step 2

Melt 1 level tablespoon unsalted butter in a medium saucepan over medium-low heat. Add the onion and cook for 4 minutes, stirring, until softened but not brown. Add the garlic and stir for 30 seconds. Lower the heat if it starts coloring.
-
Step 3

Add the potato cubes and 2 paper cups water, keeping the remaining half cup aside. Bring to a boil, partly cover and simmer gently for 12–15 minutes until a fork passes easily through the potatoes and they crush without resistance. If still firm, simmer a few minutes longer; do not mash undercooked potatoes.
-
Step 4

Turn off the heat and keep the saucepan steady on a heatproof surface. Mash the potatoes directly in their cooking liquid with a hand masher or sturdy fork until mostly smooth with a few soft pieces. Do not drain the liquid. Take care around steam and splashes; an electric blender is unnecessary.
-
Step 5

Stir in 1 paper cup milk. Mix 1 level tablespoon doenjang with 2 tablespoons warm soup in a small bowl, then stir it back into the pan. Heat gently for 3–5 minutes, stirring, until evenly hot and lightly simmering; avoid a hard boil. If too thick, add some or all of the reserved half cup water and heat through again. Divide into two bowls and add optional pepper.
Finished dish

2 soup servings. Paper cup 180 ml; level tablespoon 15 ml; small teaspoon 5 ml. Contains milk and soy; some doenjang contains wheat. This is a fusion potato soup, not traditional doenjang jjigae. No cream or extra salt is required. Refrigerate within 2 hours at 4°C or below and eat within 2 days; reheat gently until hot throughout, adding a little water if thick.
