The soup I make when summer asks for something light and quick is this one – luffa tofu egg soup, and this home cook’s version is the ten-minute bowl that uses one pot. A home cook wrote it in five steps with the timing in the title: fry the eggs, soften the luffa, simmer three minutes. I made it as written, and it is the fresh, clean summer soup that is ready before the rice.
Si gua dou fu ji dan tang (丝瓜豆腐鸡蛋汤) is luffa tofu egg soup – golden fried eggs, luffa, and tofu simmered in a light, seasoned broth.
What Is Luffa Tofu Egg Soup?
This is the simplest summer soup: two eggs are fried golden and set aside, luffa is stir-fried briefly in a little oil until soft, water joins and comes to a boil, and the tofu and fried eggs return for a three-minute simmer with salt and pepper. It is the light, clean soup that lets the luffa’s own sweetness carry the bowl.
For the mushroom-egg soup sibling of the same light pot, my tofu mushroom soup with egg trades the luffa for mushrooms.

Ingredient Notes
Eggs: Fried golden first – the rich note. My tofu mushroom soup with egg uses eggs the same way. Luffa: The summer gourd, sweet and light. Tofu: Cubed and simmered last so it stays tender. My types of tofu explained sorts the blocks.

Common Mistakes When Making This Dish
1. A greasy soup. Cause: too much oil for the eggs. Fix: a light hand. 2. Raw luffa. Cause: skipping the stir-fry. Fix: soften it first. 3. A cloudy, overcooked broth. Cause: simmering too long. Fix: three minutes. 4. Broken tofu. Cause: hard stirring. Fix: gentle. 5. A bland bowl. Cause: timid salt. Fix: season to taste.
Variations
More greens: A handful of spinach with the luffa. My tofu mushroom soup with egg is the mushroom version. Silken tofu: Use silken for a softer bite.
Frequently Asked Questions
Why fry the eggs first? The golden eggs add a rich note to the light broth. Can I use frozen luffa? Fresh is best. How long does it take? About 10 minutes. Is it spicy? Not at all. What else goes in? Salt and white pepper are enough – the luffa is the flavor, and my silky shrimp and tofu is the fuller seafood soup beside it.
How to Serve
Serve hot – with tofu mushroom soup with egg, silken tofu potage, and home-style tofu for a soup table, or with braised tofu with bok choy and savory tofu and egg stir-fry for variety.

About the Author & Recipe Development
I am Jason Guo, a Chinese chef who has cooked professionally for more than five years – including time as a head chef – and now runs my own small restaurant in China, where tofu appears on the menu almost every day. This xiachufang cook’s luffa tofu egg soup is the ten-minute bowl of my summer, and the recipe’s light touch is exactly why the luffa’s sweetness carries it. I tested it as written. I have not tested the spinach version, so that is your experiment, not my claim.
