Stuffed cucumber soup is a broth-based soup where hollowed cucumber cylinders are packed with seasoned ground chicken and simmered alongside enoki mushrooms and soba noodles in a miso-chili broth. It comes together in under an hour and uses one pot for the broth, which keeps cleanup manageable. The real reason to make it: cucumbers are cheap year-round, ground chicken is one of the more affordable proteins, and the pantry-based broth does most of the flavor work.
Substitutions that actually work
- Cucumbers: English cucumbers hold their shape best, but standard field cucumbers work fine — just peel them and scoop out the seeds more thoroughly since they’re waterier. Zucchini is a solid swap if cucumbers are expensive or out of season.
- Ground chicken: Ground turkey works identically here. Ground pork also works and adds a little more fat, which keeps the filling moist.
- Five spice powder: If you don’t have it, use a small pinch each of ground cinnamon, ground cloves, and ground anise or fennel seed. It won’t be identical but it gets you close enough.
- Miso paste: White or yellow miso both work. No miso at all? Add an extra splash of soy sauce and a small spoonful of tahini or peanut butter for body.
- Fish sauce: Soy sauce is a direct substitute. Worcestershire sauce works in a pinch — use about half the amount.
- Enoki mushrooms: Shiitake, oyster, or cremini all work. Dried shiitake rehydrated in warm water are a good budget option and the soaking liquid can go straight into the broth.
- Soba noodles: Rice noodles, ramen noodles, or thin spaghetti all work. Cook them separately and add at the end so they don’t absorb all the broth.
The technique that matters
The single technique worth getting right is how you pack the filling into the cucumber. The ground chicken mixture needs to be pressed in firmly with no air pockets — loose filling falls out during simmering and clouds the broth. Mix the chicken filling until it starts to feel slightly sticky (about 60 seconds of stirring), which means the proteins are binding. Then use the back of a small spoon or your finger to push the filling all the way through the cucumber cylinder, checking both ends. Once stuffed, sear the cut ends of the cucumber in a hot pan for about 90 seconds before adding them to the broth. That brief sear sets the filling surface so it holds together through the full simmer. Skip that step and you risk the filling loosening and breaking apart in the pot.
Troubleshooting
- Filling falls out into the broth: The chicken wasn’t mixed long enough to bind, or the cucumbers were added to boiling rather than gently simmering broth. Keep the heat at a low simmer — visible bubbles but not a rolling boil.
- Cucumbers turned mushy: They simmered too long. Cucumber goes from tender to soft quickly; 12–15 minutes in the broth is usually enough. Pull them out and rest them while you finish the noodles.
- Broth tastes flat: Miso loses its punch if it boils. Add miso off the heat or at the very end, whisking it into a ladleful of broth first before stirring it back in.
- Filling is dry or crumbly after cooking: Ground chicken is very lean. If this happens, mix a teaspoon of sesame oil or a small amount of finely minced mushroom into the filling next time — both add moisture without changing the flavor profile.
- Noodles soaked up all the broth overnight: Soba absorbs liquid fast. Store noodles separately from the broth and cucumbers, and add fresh noodles when reheating.
Leftovers and meal prep
Store the stuffed cucumbers, broth, and noodles in separate containers — combined, the noodles will absorb the broth and the cucumbers will soften further. The broth keeps in the fridge for up to 4 days and freezes well for up to 3 months. Stuffed cucumbers keep refrigerated for 2 days; they don’t freeze well because the cucumber texture breaks down. Reheat the broth gently on the stovetop over medium-low heat, add the cucumbers back in for 3–4 minutes to warm through, and cook fresh noodles to order. Ground chicken must reach 165°F (74°C) internal temperature when first cooked — use a thermometer on the first batch to get a feel for timing, then you’ll know by sight on repeat cooks.
Filling Stuffed Cucumber Soup With Chicken and Mushrooms
Ingredients
Stuffing Ingredients
1 pound ground chicken (minced chicken)
1 teaspoon salt
1 teaspoon ground black pepper- 1 teaspoon five spice - Chinese
1 tablespoon ginger - freshly grated
1 tablespoon soy sauce
5 cloves garlic - diced
1 medium green onions (scallions or green shallots) - diced
Soup Ingredients
- 4 large cucumbers - peeled
- 2 ounces Enoki mushrooms
8 cups chicken stock (chicken broth or chicken bouillon)
1 medium onion - diced- 4 tablespoons chili paste
- 1 tablespoon miso paste
1 teaspoon fish sauce- 2 bundles soba noodles
- 2 tablespoons green onions (scallions or green shallots)
2 tablespoons cilantro (coriander)- 1 whole garlic - slivered
1 medium lime
3 tablespoons rice vinegar - for topping
Instructions
- Halve each of the cucumbers through the middles. Using a long butter knife, scoop out the innards of each, scraping well and removing all the seeds until you have a nice hollow cucumber cave.
- In a large bowl, mix all the stuffing ingredients ’til combined. With a small spoon, begin stuffing each cucumber halves, bumping them on the counter to help get the air out and pack the filling in nicely.
- Once the cukes are well-filled, refrigerate them. Depending on the size of the cukes, there might be a good amount of leftover chicken mix. Make some quick mini meatballs to drop into the soup. Set these aside as well.
- Get a large dutch oven going over med-high heat with a light slick of oil or butter. Saute the onion for 5 minutes until it starts turning translucent. Add the mushrooms; they’re very delicate; look for a bit of browning. Remember to season as things go into the pot.
- Stir in the sambal, miso, fish sauce, and chicken stock. Bring to a boil.
- Take the cukes out of the fridge and slice each into 2 to 3 pieces to make them more manageable for serving later. Slide the cucumbers and mini meatballs in, reduce heat, and simmer for 30 minutes.
- Add the soba noodles and simmer for another ten minutes.
- To serve, ladle up big bowlfuls and give each serving a scattering of chopped scallions and herbs and a swirl of rice vinegar or lime juice for brightness.

Your questions, answered
Can I prep the stuffed cucumbers ahead of time?
Yes — stuff the cucumbers up to 24 hours ahead and keep them covered in the fridge. Don’t sear them until you’re ready to cook, since the raw cut ends help seal in the filling during that step.
What if I can’t find soba noodles at my store?
Any thin noodle works here — rice vermicelli, ramen noodles, or even thin spaghetti are all fine substitutes. Cook them separately according to package directions and add them to the bowl at serving time rather than simmering them in the broth.
How do I know the chicken filling is fully cooked inside the cucumber?
Use an instant-read thermometer inserted into the center of the filling — it needs to read 165°F (74°C). If you don’t have a thermometer, cut one cucumber in half after the recommended simmer time; the filling should be completely opaque with no pink remaining.
