💡 Chef's Guide: Expert Tips

Drawing on a decade of experience in Michelin-starred kitchens and Cordon Bleu training, I have compiled my top tips for recipe success.

  • Garnishing: Top with a dollop of sour cream or yogurt for a creamy finish.
  • Thicker Consistency: For a thicker soup, mash some of the lentils and potatoes directly in the pot using a potato masher.
  • Umami Boost: A teaspoon of soy sauce or miso paste can deepen the savoury flavours without making the soup taste like soy or miso.

🍯 Storing and reheating leftovers

  • Fridge: Store the cooled soup in an airtight container in the fridge for up to 4 days.
  • Freezer: For longer storage, place the soup in a freezer-safe bag or container and freeze for up to 3 months.
  • Reheat: To reheat, warm the soup on the stove over low heat, stirring occasionally, until heated through. If frozen, thaw in the fridge overnight before reheating.

    I also had to add more soup and also added some cream I had in the fridge. As I wasn’t able to get pancetta I substituted guanciale. It’s very very tasty and the half is frozen for later.

    1. So happy you adapted this recipe to what you had available to use. This soup freezes so well, too! Thank you so much for taking the time to leave a comment. It's so appreciated! 🙂

    I had to almost double the vegetable stock because the lentils absorbed most of the liquid. The lemon juice was a bit much for me. Next time, I will probably just use the juice of half a lemon. But it was delicious.

    1. Sorry to hear that. If you're US based that may be why. Both items are very common in our shops. You can always substitute smoked bacon and use any soft herb. But rest assured the items I've seen in US Aldi stores are so inventive and fun. Most of our items here are very basic.

    When do you add the lardon bits? Presume at the end with the spinach? Super recipe, can't wait to taste it, it's simmering now.

    1. Hi Shannon. So sorry I missed that. Yes. Add them back to the pan at the end. I like to save a couple to add to the top of the bowls right before serving, but you can just add them all back in too. The recipe has been updated to reflect that. Enjoy! 🙂
