All the Pieces for This Meal
- 1 tablespoon butter, ghee, or coconut oil for sautéing the base.
- 1 small yellow onion, chopped nice and fine to melt into the soup.
- 2–3 tablespoon Thai red curry paste, your flavor powerhouse.
- 1–2 cloves garlic, minced for that extra punch.
- 1 inch knob of fresh ginger, grated fresh for zing and warmth.
- 5 cups good quality broth – veggie or bone broth works great here.
- 1 ½ cups red lentils, soaked and rinsed so they cook perfect in no time.
- 2 cups chopped sweet potatoes for natural sweetness and hearty texture.
- 3 cups kale, de-stemmed and thin ribbons for a nice leafy bite.
- ½ cup full fat coconut milk to round it all out smooth and creamy.
- Juice from 1 lime and salt to taste, plus cilantro and lime wedges for garnish.

Walking Through Every Single Move
Start by heating your butter, ghee, or coconut oil right in the pressure cooker on medium heat. You wanna get that nice melt so the onion cooks evenly.
Add your chopped onion and cook it until it’s translucent and soft. It usually takes about 5 minutes. You’ll notice the smell start to build here, so dang, you’re already winning.
Now stir in your red curry paste, minced garlic, and grated ginger. Keep everything moving for 1 to 2 minutes until you can really sense the spices getting fragrant. That’s your cue.
Pour in your broth, then add the soaked and rinsed red lentils along with the chopped sweet potatoes. Give everything a good stir to combine.
Lock the lid on the pressure cooker making sure your sealing ring is set right. Then bring to high pressure. When it hits pressure, you’ll hear the valve hiss – that’s your timer to reduce heat.
Let it cook for about 20 to 25 minutes, enough time for lentils and sweet potatoes to get soft but not mushy. Once done, use the natural release method so the steam vents slowly and the soup thickens nicely.
Open the lid and toss in your kale with the coconut milk. Stir it well and let it cook for another 5 minutes on low heat until the kale wilts and gets tender.
Finish with a squeeze of lime juice and salt to taste. You’re ready to serve up a bowl of this delicious soup, garnish with fresh cilantro and more lime wedges if you want that fresh pop.
Smart Shortcuts for Busy Days
- Use pre-chopped onions and garlic from the store if you’re rushing.
- Grab pre-soaked lentils or soak a batch ahead so you’re ready anytime.
- Frozen sweet potatoes already chopped save you a step without losing flavor.
- Keep a jar of good quality red curry paste in your fridge for all quick meals.
- Use canned coconut milk that’s BPA free and give it a quick stir before measuring.
The Flavor Experience Waiting for You
When you take the first spoonful, you’ll notice that spicy warmth from the red curry. It’s bold but not overwhelming, kinda comforting like a hug in a bowl.
The lentils soak up all those rich broth and curry flavors, making every bite hearty and satisfying. The sweet potato adds a subtle sweetness that balances out the heat just right.
The kale gives a fresh, slightly bitter crunch that contrasts nicely with the creamy coconut milk. It’s like a little green surprise that keeps things interesting.
You finish it off with a squeeze of lime, brightening up the whole soup and leaving you wanting more. Trust me, you’ll be licking the bowl clean.

How to Store This for Later
If you got leftovers, pour your soup into airtight containers and pop ’em in the fridge. It lasts about 4 to 5 days and tastes even better as the flavors meld.
For longer storage, freeze in single or family-sized portions. Use freezer-safe containers so your soup stays fresh and ready for quick meals.
When you reheat, warm it over medium heat on the stove or use your microwave. Give it a stir so the coconut milk mixes back in good and even.
If the soup thickens too much after chilling, add a splash of broth or water and stir it while warming. It loosens the texture without losing any punch.
What People Always Ask Me
- Can I use other lentils instead of red? You can but red lentils cook fastest and give that creamy texture. Brown or green ones take longer and might need more water.
- What if I don’t have fresh ginger? Powdered ginger works in a pinch, but fresh grated gives way better flavor and brightness.
- Can I skip the coconut milk? You can, but coconut milk makes the soup creamy and smooth. Without it, the soup is more brothy and less rich.
- How do I know when the pressure cooker is done? Usually 20-25 minutes under high pressure does it. You’ll hear the valve hiss when it reaches pressure, then count down your timer.
- What’s the sealing ring for? It keeps the lid sealed tight so the cooker builds pressure. If it’s misplaced or worn, steam will leak and cooking won’t be right.
- Is the natural release important? Yep, it helps the soup thicken and prevents hot steam blasting out too fast. Quick release can mess with texture here.
