Instant Pot Jain Tomato Soup (No Onion, No Garlic)

On the nights when I want something warm and red in a bowl but my kitchen is in a no onion, no garlic season, I still want depth. Not a thin broth that tastes like missed steps, but a real soup that carries tomato tang, a little natural sweetness, and enough body to count as dinner beside toast or khichdi.

That is how this Instant Pot Jain tomato soup landed in our rotation. It leans on Roma tomatoes for acidity and color, dudhi (bottle gourd, lauki) for a silky base once blended, and carrot for a quiet sweetness that rounds the tomatoes without leaning on alliums. The pressure cooker does the long simmer in one sealed go, then I blend right in the pot or in a jar blender until the texture feels like a cafe-style tomato soup, not a watery puree.

If you want a Jain-friendly bowl that still feels like a treat, come cook it with me.

What does “Jain-style” mean in this soup?

In many Jain homes, everyday cooking skips onion, garlic, and often underground vegetables depending on how your family observes. This recipe is written without onion and garlic, and the savoriness comes from cumin, gentle turmeric, optional Kashmiri chili for color, and the slow release of tomato flavor under pressure.

Some households also skip hing (asafoetida) or certain root vegetables. I use carrot here for a little natural sweetness that balances sharp tomatoes. If your table avoids root vegetables, swap the carrot for more peeled dudhi or diced zucchini and you will still get a lovely bowl.

If you want a grain pairing from the same no-onion-garlic headspace, I often serve this beside jowar sabudana khichdi on a light dinner night.

Why Roma tomatoes, dudhi, and carrot together

Roma tomatoes give a more reliable soup base than oversized salad tomatoes: less water per bite, quicker collapse, cleaner color. Dudhi adds volume and a mild note that disappears into a creamy mouthfeel once blended, which helps when you are not using cream or cashew paste. Carrot lifts sweetness so you need less sugar or jaggery trickery at the end.

Why you’ll love this recipe

• True Jain-friendly base: No onion, no garlic in the ingredient list as written.

• Silky without dairy: The blended dudhi does the heavy lifting for body.
• Meal-prep friendly: Flavors meld overnight; thin with a splash of water when reheating.
• Easy to tune: More lemon at the end, a pinch of sugar only if your tomatoes are sharp, chili only if you want heat.

Ingredients

Serves 4 as a light main with bread or rice

Tempering

• 2 tbsp neutral oil (sunflower or grapeseed)
• 1 tsp cumin seeds
• 1 bay leaf (optional)
• ⅛ tsp hing (asafoetida), optional (skip if you do not use it)

Vegetables

• 500 g Roma tomatoes (about 5 medium), cores removed, roughly chopped
• 250 g dudhi (bottle gourd / lauki), peeled, seeds scooped if very mature, diced
• 80 g carrot (about 1 small), peeled and diced small

Spices and liquid

• ½ tsp turmeric powder
• ½ to 1 tsp Kashmiri red chili powder (optional, for color and very mild heat)
• 1¼ to 1½ tsp fine salt, plus more to taste after blending
• 2½ to 3 cups water (use the higher amount if tomatoes look firm or small)

Finish

• 1 to 2 tsp lemon juice, to taste
• 2 tbsp chopped cilantro (optional)
• ¼ tsp sugar or a tiny pinch of jaggery, only if tomatoes are very sharp

Equipment: 6-quart Instant Pot or similar electric pressure cooker, immersion blender or countertop blender, heat-safe silicone spatula.

Pro tip: If your tomatoes are very juicy on the board, start with 2½ cups water. You can always thin after blending. Dry winter Romas sometimes want the full 3 cups.

How to make Instant Pot Jain tomato soup

Temper and soften tomatoes

1. Set the pot to Sauté (Normal). When the display reads Hot, add oil. Add cumin seeds and optional bay leaf. Let cumin sizzle 20–30 seconds until fragrant, not brown.
2. If using hing, add it and stir 5 seconds off the heat or on Low sauté so it does not scorch.
3. Add chopped Roma tomatoes with a small pinch of the measured salt. Cook 4–6 minutes, stirring often, until the tomatoes slump and release liquid. Scrape the bottom so nothing cakes before pressure.

Add vegetables, spices, pressure

1. Stir in dudhi and carrot. Add turmeric, optional Kashmiri chili, and remaining salt.
2. Pour in water. Stir once, level the mixture, and scrape any tomato bits from the pot sides back into the liquid.
3. Cancel Sauté. Seal the lid, valve to Sealing. Cook on Manual / Pressure Cook on High for 6 minutes.
4. When the timer ends, let pressure natural release for 10 minutes, then quick-release any remaining steam. Open the lid away from your face.

Blend and finish

1. Cool slightly if you are using a countertop blender; never fill a blender jar to the top with hot liquid. With an immersion blender, blend directly in the pot until completely smooth.
2. If you want a restaurant-fine texture, pass the soup through a fine mesh strainer using the back of a ladle. I often skip straining for a home-style bowl.
3. Set Sauté on Low if you need to reheat after blending. Stir in lemon juice. Taste salt and acidity. Add the tiny sugar or jaggery pinch only if the soup still tastes harsh.
4. Serve hot, scattered with cilantro if you use it.

Tip from experience: If the soup tastes flat right after blending, salt is usually the fix before sugar. Lemon wakes tomato soups more than extra chili.

Tips for the best texture and flavor

• Dice dudhi evenly so nothing stays crunchy while carrots are already soft.
• Do not skimp the post-pressure rest. A short natural release keeps foamy tomato soups calmer when you first open the lid.
• Blender safety: blend in batches, vent the lid, cover with a towel, and start on low speed.
• Thickness: if the soup is too thick after blending, stir in hot water ¼ cup at a time.

FAQs

Q1. Can I make this strictly without root vegetables?

Yes. Omit carrot and use an extra 100 to 150 g peeled dudhi or diced zucchini. Cook time stays the same.

Q2. Can I skip hing?

Absolutely. The bay leaf and cumin still carry a clear Indian tempering line.

Q3. Can I make this on the stovetop?

Yes. Simmer covered until everything is very tender, 25 to 35 minutes depending on dice size, then blend. Stir occasionally so the bottom does not catch.

Q4. How do I store leftovers?

Cool completely, refrigerate in a clean airtight container up to 3 days. The soup thickens as it sits. Reheat gently with a splash of water.

Q5. Can I freeze it?

You can, up to about 6 weeks in a freezer-safe container with headspace. Texture may separate slightly; re-blend after thawing for the smoothest result.

Q6. What pairs well with this soup?

Buttered toast, plain khichdi, or a simple jeera rice on the side. A thin dal rounds the meal nicely: palak dal is an easy match. For a no-onion-garlic rice idea from the same pressure-cooker family, bookmark Instant Pot jeera rice for another calm dinner night.

Closing

Instant Pot Jain tomato soup is the recipe I pull out when I want color and comfort without building flavor from alliums. It asks for honest tomatoes, a patient blend, and one good squeeze of lemon at the end.

If you try it, tell me: do you prefer yours with a little Kashmiri chili for blush-pink heat, or completely mild and lemon-bright?
