Step timeline inside the pot six to eight
First you hit saute mode on your six quart pressure pot for about 8 minutes.
Add a tablespoon olive oil, the chopped onion, and a pinch of salt to coax the onions soft and sweet. Remember to stir occasionally so they don’t stick.
Cancel saute once onions are translucent. Next toss in celery, carrots, garlic, and one teaspoon salt. Stir it good, then add in the lentils, diced tomatoes, stock, and bay leaf. Give it a stir to combine.

Seal the lid and bring your cooker up to pressure. When the timer dings, go for a slow release by lettin the pressure ease naturally for 15 minutes. This helps broth depth and texture in the soup.
Open the lid and fish out that bay leaf. Stir in the teaspoon red wine vinegar which brightens the flavors up real nice.
If the soup looks thick you can thin it out with a cup or two more stock. Taste then add the other teaspoon of salt. You recall that seasoning can always be late to the party so adjust as you go.
Next grab your immersion blender or safe blender and blitz just a few seconds, 5 to 10 tops. This adds creaminess but keeps some lentils and veggies texture alive.
Finally fold in the baby spinach leaves. Stir ’em through till they wilt slightly in the warm soup. Serve it up with a drizzle of olive oil or any topping you like.
Shortcut valve tricks three to five
This one’s all about knowin your cooker valves to get dinner ready fast and tasty. You gotta watch for the steam cues.
Want to speed things up at the end use quick release. Just carefully push the valve so the steam hisses out fast. But beware it might thin your broth if you do this too early cause all that steam carries flavor.
Slow release is your go to for soups cause it keeps the broth rich and flavors melded. Letting the pot release pressure on its own for 15 minutes or so is perfect.
If you see too much broth boiling out or the soup is thicker than you like, just add more stock during the last stir. You recall soup texture’s a personal thing so feel free to adjust it to your liking.
First spoonful story
That first spoonful is a real moment worth savin.

Leftover jar guide
Got leftovers? You did good cause lentil soup tastes even better the next day.
Fill up airtight jars or containers with the cooled soup. If you like the broth deep, keep the spinach separate and stir it in fresh each time while reheating.
When ready to eat, heat gently on stove medium low, stirring now and then so the lentils don’t stick to the pan.
If you notice soup holds too thick after chilling, add a splash of stock or water when warming to loosen it up to your liking.
Pro tip keep your leftover soup for up to 4 days in the fridge or freeze for longer storage. Just thaw in the fridge overnight before warming up again.
And remember the quick release trick when reheating in pressure cookers, better to use stove or microwave for gentle warming.

What if I dont have baby spinach can I use something else
Yeah sure you can swap in kale, Swiss chard, or even arugula if you want. Just add it at the end like spinach to keep that fresh vibe.
How do I adjust cooking time for brown lentils instead of green ones
Brown lentils work great too but sometimes need a bit less cooking, keep an eye after 20 minutes at pressure to see if they are tender enough.
Can I make this soup vegetarian or vegan
Totally it’s super flexible use veggie stock in place of chicken stock to keep it plant based.
What if my soup is too thick after cooking
Just add more stock or water little by little and stir it through till you hit your preferred broth depth.
Is it okay to quick release pressure for this soup
You can but the slow release really helps bring out flavors and keeps lentils from breaking down too far so I recommend that most.
Can I freeze leftover soup
Yep it freezes beautifully. Just thaw overnight in the fridge and reheat gently on the stove or microwave so the lentils stay tender without getting mushy.
