Instructions
- Prep. Dice all the vegetables and prepare all the ingredients you need for the recipe. You can start with the onions, celery and carrots as those get cooked first, giving you a few minutes to do the rest of the veggies. If using vegetable stock cubes, prepare the stock first.
- Sauté. Turn the Instant Pot and press the Sauté button. It should say Normal on the display (this indicates heat level). Allow the bottom to heat up for a couple of minutes, then add the olive oil, onions, carrots and celery and cook for 2-3 minutes, stirring a couple of times. Press Cancel or Keep Warm/Cancel to stop the Sauté.
- Add ingredients. Then add the garlic, spices, salt and pepper followed by zucchini, sweet potatoes and dry lentils (no need to soak the lentils for this recipe!).
- Pour in the stock and stir. Add the tomato paste and diced canned tomatoes and stir slightly.
- Set & cook. Secure and lock the lid; make sure the pressure handle is pointing to Sealing on Duo Classic. Select Manual/Pressure Cook and adjust the timer to 8 minutes on HIGH pressure.After a few beeps/seconds, the ON sign will come on indicating the pot is heating up and the pressure is building; pressurizing will take about 12 minutes and then the 8-minute timer will begin.
- Once the timer is done, allow the pressure to release naturally for about 10 minutes. Then use the quick release method to let off the remaining pressure (press the steam knob down or point to Venting on older models).
- Finish the stew. Open the lid and stir in 1 teaspoon of lemon zest, 1-2 tablespoons chopped parsley and 2 tablespoons lemon juice. Taste for salt and pepper.
Notes
- Saute time: 3 minutes | Pressurizing: 12 minutes | Cooking at pressure: 8 minutes | Release: 10 minutes natural followed by quick release | Total cooking time: 23 minutes.
- Storage: You can store this lentil stew for up to 4 days in the refrigerator or freeze it for up 3 months. Make sure to cool down before storing. Defrost in a fridge overnight or in a microwave and reheat well.
- Serving suggestions: Serve as is with a side of crusty bread, dinner rolls or buttered toast; top with croutons; you can stir in some cheese, sour cream, or yogurt on top. The stew can also be served over rice, pasta, couscous, quinoa, or cauliflower rice/vegetables.

Ee
I accidentally put 7mins to pressure cook and the lentils came out a little underdone ,would 1minute have really made much difference? (I want to make this recipe again) I also let the pressure release naturally, not sure if that counts for some amount of cooking time.... I ended up not chopping the courgettes at all (just the hard tips )which worked fine, they would be cut when cooked when I mixed with a large spoon. I used chopped frozen veg but had to guess because I didn't know what the average weight of a carrot onion etc... are . Would have been great to have weights and non cup measurements such as millimetres and grams... mainly because I also have the 6quart IP & wouldn't want to overfill it. I did try to cook it after but because I had mixed the food more at that stage got the burn warning, which apparently gets triggered by tomato.

Can this recipe be doubled or even trebled? What is the maximum that I could cook in one lot.

This depends on the size of your Instant Pot. When we made this recipe, we fed 8 people with it so it's already quite a large batch. It as made in the 6-quart Instant Pot and I remember when I put everything in the pot before cooking, I still had a bit of space before the Max line but not enough for a double the volume. I could have added another quarter of all ingredients. If you have an 8-quart Instant Pot, then you can easily double it. As long as your food/liquid volume stays below the Max line of the Instant Pot, you can make a bigger batch.
