Vegan Banana Blossom Salad (Goi Bap Chuoi) to Serve With Banh Mi

Short answer: Vegan gỏi bắp chuối (banana blossom salad) is made by slicing the pale inner bracts of a banana flower paper-thin, soaking them in acidulated water so they stay white, then tossing them with herbs, carrot, crispy tofu or mushrooms, roasted peanuts and a sweet-sour lime and soy dressing. It serves 4 in about 40 minutes. The result is crunchy, slightly astringent and very fresh, a perfect side for a rich banh mi. Canned banana blossom works when fresh ones are unavailable.

What banana blossom is

The banana blossom, or banana flower, is the large teardrop-shaped bud that hangs at the end of a banana bunch. Under its tough purple outer layers are pale, tightly wrapped bracts and rows of small florets. In Vietnam, bắp chuối is sold at markets almost everywhere and appears in salads, as a shredded garnish for noodle soups and in braises. Its flavour is mild and slightly bitter, and its texture when finely sliced is crisp and a little fibrous, a bit like a cross between cabbage and artichoke.

Vegetarian versions of the salad are common in Buddhist restaurants and on vegetarian days, using tofu, mushrooms or soy "chicken" instead of meat. As a side with banh mi it brings a different kind of crunch from the pickles inside the sandwich, and it looks spectacular on a table. More pairings are in our sides, soups and salads section.

Fresh or canned?

Fresh banana blossoms are sold in many Asian groceries, especially Vietnamese, Thai and Filipino shops, and sometimes in large supermarkets. Canned banana blossom in brine has become widely available in recent years, partly because of its popularity as a plant-based "fish" substitute. The two behave differently:

Ingredients (serves 4 as a side)

• Banana blossom: 1 medium fresh blossom, or 2 cans in brine plus 150 g finely shredded white cabbage
• Acidulated water: 2 litres cold water with the juice of 1 lime or 2 tbsp white vinegar
• Carrot: 1 medium, julienned
• Firm tofu: 200 g, pressed and cut into thin strips, or 200 g oyster mushrooms torn into strips
• Herbs: a large handful each of rau răm (Vietnamese coriander) and mint; Thai basil or cilantro if needed
• Roasted peanuts: 50 g (1/3 cup), crushed
• Fried shallots: 3 tbsp
• Toasted sesame seeds: 1 tbsp (optional)

Dressing

• Lime juice: 3 tbsp
• Sugar: 2 1/2 tbsp
• Light soy sauce or vegan fish sauce: 3 tbsp
• Warm water: 3 tbsp
• Garlic: 2 cloves, minced
• Fresh chili: 1–2, finely chopped

Method

1. Prepare the water (2 minutes). Fill a large bowl with the cold water and lime juice or vinegar. Have it ready before you cut, because banana blossom browns within a minute of slicing.
2. Peel the blossom (5 minutes). Wear gloves or rub your hands with a little oil, since the sap is sticky and stains. Peel away the tough dark purple outer bracts and the florets underneath until you reach the pale, tightly packed inner core, usually after removing a third to half of the blossom.
3. Slice (5 minutes). Halve the core lengthwise and slice it crosswise as thinly as you can, ideally 1–2 mm. Drop the slices straight into the acidulated water as you go and push them under.
4. Soak and squeeze (15 minutes). Leave the slices in the water for 15 minutes, swishing occasionally to release the sap. Drain, then squeeze firmly by the handful and pat dry. This reduces bitterness and keeps the strands crisp.
5. Cook the protein (8 minutes). Pan-fry the tofu strips in 2 tbsp oil until golden and chewy, about 6–8 minutes, splashing with 1 tsp soy sauce at the end. For mushrooms, sear in a hot pan until browned and dry, then season with salt and pepper.
6. Make the dressing (3 minutes). Dissolve the sugar in the warm water, then stir in the lime juice, soy sauce, garlic and chili. Taste for a clear sweet-sour-salty balance.
7. Toss and serve (3 minutes). Combine banana blossom, carrot, protein and most of the herbs, pour over three-quarters of the dressing and toss well. Top with peanuts, fried shallots, sesame and the remaining herbs. Serve within 15 minutes.

Using canned blossom: drain, rinse and squeeze it, tear it into thin strips, and mix it with finely shredded cabbage before dressing. Skip the soaking step.

Common mistakes and fixes

• Brown, grey slices: they sat in the air too long. Slice directly into acidulated water, and work quickly.
• Too bitter or astringent: slices were too thick or not soaked enough. Slice thinner and soak a full 15 minutes.
• Tough, chewy strands: outer bracts were included. Use only the pale inner core.
• Watery salad: the blossom was not squeezed dry, or it was dressed too early.
• Stained hands: wear gloves next time, or rub hands with oil before peeling; lemon juice helps remove stains.

Nutrition and allergens

Banana blossom is low in calories and adds fibre and bulk to a meal, but nutrition data for it is limited, so we do not quote figures here. Most of the energy and protein in this salad come from the tofu and peanuts: USDA FoodData Central lists firm calcium-set tofu at about 17 g protein per 100 g, so 200 g shared among four adds about 8–9 g of protein per serving, and the peanuts add a few grams more along with healthy fats. Peanuts are a common allergen; toasted sunflower or pumpkin seeds make a good swap. If anyone avoids soy, replace the tofu with seared mushrooms and use coconut aminos in the dressing instead of soy sauce. Anyone with a known latex or banana allergy should check with a doctor before eating banana blossom.

Variations

For a more substantial salad, add 100 g cooked rice vermicelli and turn it into a light main course. For extra crunch, add shredded cabbage, bean sprouts or jicama. Store-bought vegan "chicken" strips or soy curls, rehydrated and fried, are popular in vegetarian restaurants in Vietnam. A spoonful of chili sauce or chili oil makes a bolder dressing; see our sauces and spreads section for homemade versions. If you cannot find rau răm, a mix of mint and cilantro gives a similar fresh, peppery lift; our pickles and herbs guides cover more herb swaps.

Serving with banh mi

Serve the salad in a shallow bowl in the centre of the table with the banh mi cut in halves, so everyone takes a little of each. Its gentle bitterness and crunch reset the palate between bites of a rich mayo-and-pâté sandwich. For a light lunch for four, two banh mi cut in half plus a big bowl of this salad is enough for most appetites; for dinner, add a soup. Leftover dressed salad softens and darkens, so dress only what you will eat; undressed sliced blossom keeps in acidulated water in the fridge for up to a day.
