Clear Potato and Onion Soup for One: Slice Potatoes to 3 mm
The thickness of the potatoes matters just as much as the cooking time in potato soup. Simmer thinly sliced potatoes and onion together, then finish seasoning when the potatoes split easily under the tip of a spoon. The trick is not to stir the pieces vigorously before ladling the soup.
Before cooking for one
Start with an ingredient you already have, then check the recipe's full ingredient list, quantities and equipment before choosing your meal. For a solo meal, use its one-serving quantities.
Halve the peeled potatoes and place the cut side on the cutting board to make them easier to slice. Cut them to 3 mm thick, and thinly slice the onion too. If some potato pieces are thick, a few may still be firm after 8 minutes. Prepare the garlic and green onion before turning on the heat.
Ingredients for 1 serving
- Potato: 1 small potato
- Onion: 1/8 medium onion
- Green onion: 1/8 stalk
- Garlic: 1 clove
- Water: 2 paper cups (180 mL each)
- Soy sauce: 1/2 household eating spoon
- Salt: 1 pinch
These amounts are based on the 1-serving ingredient list in the app. Household eating spoons and pinches are everyday measures and have not been converted to exact grams or milliliters. Check the package size and cup capacity shown in parentheses as well.
Instructions
- Step 1. Rinse and peel the potatoes, halve them, and place the flat side down. Slice them 3 mm thick, thinly slice the onion, and cut the green onion into 0.5 cm pieces. Mince the garlic.
- Step 2. Add the water, potatoes, onion, and garlic to a pot. Once it comes to a boil, reduce the heat to medium-low and simmer for 8 minutes.
- Step 3. When a potato splits easily as you press it with the tip of a spoon, add the soy sauce and green onion. Add half of the prepared salt to start, and simmer for another 1 minute.
- Step 4. Turn off the heat and ladle the soup into bowls without breaking up the potatoes. Let each spoonful cool before eating.
When the potatoes are still firm after cooking
Before turning off the heat, press a piece of potato with a spoon. If it is firm, check whether it needs more cooking. Conversely, potatoes that have softened will break apart if you keep stirring them. Add the soy sauce and green onion, then start with half of the prepared salt and adjust the seasoning to finish.
How to ladle the clear broth
Support the potatoes from underneath as you transfer them with a ladle, and let each spoonful cool before eating. The ingredient list calls for one small potato and two cups of water, using a 180 mL cup. If you count a large potato as one small potato, the ratio of solids to broth may change.
