Make up a big pot of this comforting Bacon and Lentil Soup today - it's hearty, filling and perfect for a cold winter's day. Packed with chunky brown lentils, carrots, onion, celery and the smoky flavour of bacon, it's finished with a little Worcestershire sauce and balsamic vinegar for just the right amount of tanginess.

I always keep lentils in my pantry because they are great for bulking out soups without needing lots of expensive or complicated ingredients. Brown lentils work perfectly in this recipe as they keep a little bite and make it feel like a proper meal in a bowl. It's also great for freezing, so you can enjoy a cosy, homemade bowl of soup whenever you need something warming and delicious.

Ingredients Notes
To make this recipe you will need the following ingredients:
- Bacon: Use lean back bacon or bacon medallions with all visible fat removed. It adds a lovely smoky flavour to the soup and works perfectly with the earthy lentils.
- Brown lentils: Dried brown lentils are best for this soup as they hold their shape and keep a little bite, making the soup hearty and filling. Rinse them well before adding to the pan.
- Vegetables: Onion, garlic, celery and carrot create a simple flavour base for the soup.
- Stock: Vegetable stock keeps the flavour light while still adding plenty of depth.
- Tomato paste: This adds richness and helps deepen the flavour of the broth. It also gives the soup a lovely colour and works really well with the bacon, lentils and herbs.
- Mixed herbs: Dried mixed herbs are perfect here for an easy all-round seasoning. Italian herbs or herbes de Provence can also be used.
- Balsamic vinegar and Worcestershire sauce: Just a splash of each adds a little tanginess and depth to the soup, balancing the smoky bacon and earthy lentils.
- Fresh parsley: A sprinkle of chopped Italian parsley at the end adds freshness and a lovely pop of colour.
- Olive oil spray: Used for sautéing the bacon and vegetables without needing lots of oil. Make sure the pan is nicely heated before adding the ingredients so they soften and lightly colour rather than steam.
Once you've gathered all the ingredients and prepared them accordingly, you're all set to create this easy and delightful recipe.
See the recipe card for specific quantities and instructions.
Variations and Substitutes
This soup is easy to adapt depending on what you have on hand.
- Swap the lentils: Replace the brown lentils with canned cannellini beans, butter beans, chickpeas or mixed beans. Add canned beans towards the end of cooking as they are already cooked.
- Use chicken instead of bacon: Diced chicken breast or thigh works well for a lighter version. A little smoked paprika can help replace the smoky flavour of the bacon.
- Try sausage: Lean pork, chicken or turkey sausages add plenty of flavour and make the soup even heartier. Smoked sausage is especially delicious.
- Make it vegetarian: Omit the bacon and add extra beans, mushrooms or vegetables. A pinch of smoked paprika adds great depth of flavour.
- Add extra vegetables: Potatoes, sweet potatoes, butternut squash, kale, spinach, leeks or peppers are all great additions and make the soup even more filling.
- Adjust the texture: Blend a portion of the soup for a thicker, creamier consistency, or add a little extra stock if you prefer it thinner.

Side Suggestions
This soup is hearty enough to enjoy on its own, but there are plenty of ways to turn it into an even more satisfying meal.
- Crusty bread or a warm bread roll for dipping into the rich broth.
- A slice of wholemeal or sourdough toast topped with a little butter.
- Homemade soda bread or cheesy spring onion oat bread
- A grilled cheese sandwich for the ultimate cosy lunch or dinner.
- A simple green salad with a light vinaigrette to balance the richness of the soup.
- Crackers or crispbreads for a little crunch on the side.
- A sprinkle of grated cheddar or parmesan over the soup before serving.
- Extra fresh parsley and a twist of black pepper for a simple finishing touch.
Storing, Freezing and Reheating
Storing: Allow the soup to cool completely, then transfer to an airtight container and store in the refrigerator for up to 4 days. The lentils will continue to absorb liquid as the soup sits, so it may thicken slightly.
Freezing: This soup freezes really well. Portion into freezer-safe containers and freeze for up to 3 months. Leave a little space at the top of the container to allow for expansion.
Reheating: Defrost overnight in the refrigerator if frozen. Reheat on the stovetop over a medium heat until piping hot, stirring occasionally. You can also reheat individual portions in the microwave. If the soup has thickened during storage, simply add a splash of stock or water to loosen it to your preferred consistency.

How many days will a soup like this last without freezing. Can you refrigerate and have it the next 2 days?

Shevy (Slimming Eats) says
Hi Sophie, my general rule is no more than 4 days for something in the fridge, so if I think it won't get used in that time, I will freeze it. Hope that helps 🙂

Fantastic, my husband and I have just finished 2 bowls each!! I added one fresh tomato chopped, and a chopped yellow pepper just to use them up. Went very well together. Also I only had normal vinegar, which tasted fine. Goes perfect with feta cheese on the side and plenty of bread (obviously that's adding calories though)... Thanks very much, I will be making this again!
Shevy (Slimming Eats) says
mmmm that does sounds good, thanks for sharing. Could always save a healthy extra B of bread to do that too, but just with the feta sounds yum!!.
Moira Fox says

Just delicious and so healthy too. I added a couple of handfuls of chopped spinach that needed using up, went very well. Thanks for all the lovely recipes
Hannah says
Just made this and enjoyed it for lunch! I did it in the instant pot because I wash pushed for time And it turned out great! Followed the recipe but then just cooked on high pressure for 14 mins and then NPR. I might just go and get another bowl! 🙂
Shevy (Slimming Eats) says
so glad you enjoyed it, it is definitely one of my go-to soups.
Emma says
I only have a tin of green lentils (not dried). Can I use these and reduce down the stock?
