Ingredients Notes
To make this recipe you will need the following ingredients:
- Onion: Adds sweetness and flavour to the base of the sauce as it cooks down.
- Garlic: Fresh garlic adds lots of savoury flavour and works perfectly in a rich tomato based sauce.
- Carrot: Adds natural sweetness and helps give the bolognese a lovely hearty texture.
- Zucchini (Courgette): Blends beautifully into the sauce while adding extra vegetables and goodness.
- Sweet Potato: Adds a subtle sweetness and helps make the sauce extra rich and comforting.
- Fresh Tomatoes: Add freshness and extra flavour to the sauce as they cook down.
- Dried Brown Lentils: The star of the dish, adding protein, fibre and a delicious hearty texture. Make sure to rinse well before cooking.
- Passata or Crushed Tomatoes: Forms the rich tomato base for the bolognese sauce.
- Vegetable Stock: Adds depth of flavour and helps cook the lentils until perfectly tender. Be sure to use the right ratio of stock cubes or paste to water for a balanced, tasty broth. Too little and it'll taste flat; too much and it can become overly salty.
- Tomato Paste: Adds richness and helps intensify the tomato flavour.
- Mixed Herbs: Add extra savoury flavour and work perfectly with the tomato sauce.
- Salt and Black Pepper: Important for seasoning and balancing the flavours.
- Balsamic Vinegar: Just a small splash helps balance the acidity and adds extra depth to the sauce.
- Olive Oil Spray: Used for softening the vegetables without needing lots of oil.
- Fresh Italian Parsley and Basil: Add freshness and the perfect finishing touch when serving.
Once you've gathered all the ingredients and prepared them accordingly, you're all set to create this easy and delightful recipe.

Jenny Robinson says

lucie42 says
can I check tomato paste is tomato puree?
bubbyk says
yes they are the same thing lucie
frugalfifer says
looks great, I too am trying to introduce more pulses into my diet, one to try later in the week. thanks for posting
Terry Heath says
Is 2 hours coking time on the stove the right time - thought the veg would disappear in that time?
Siobhan (Slimming Eats) says
yes it is 2 hours cooking time, on a very low heat. The slow cooking improves the flavour, you could cook it for a shorter time if you prefer on a slightly higher heat.
disqus_S1Y0q928HW says
Could you use red lentils instead?
Jade says
I've just made a massive batch of this! Is it onto freeze some portions? Thank you! X
Siobhan (Slimming Eats) says
yep this is fine to freeze 🙂
Emzy says
This sounds amazing. Do you know the calories per portion please?
Many thanks x x x
Shevy (Slimming Eats) says
This is one of my older recipes, where I haven't got round to adding nutritional info etc yet, I will hopefully get it worked out soon.
Betsie says
Can I check if the calorie count includes the pasta, or is this just for the sauce?
Shevy (Slimming Eats) says
the approx calorie count, is always only for what is in the ingredients list. So for this it will be just the bolognese 🙂
Caroline says
Can you use red split lentils? I can’t seem to find brown ones. X
Shevy (Slimming Eats) says
Chunky lentils like brown or green are best, as they hold their shape.
Sam says
Can I do this in a slow cooker? If so, what time do you recommend?
Claza says
How long would you do this in the instant pot for?
Shevy (Slimming Eats) says
I haven't had a chance to test this out in the instant pot, but I would brown as per normal and cook for 12-15 minutes with a quick release.
Katie Davies says
Stupid question. (New to lentils). If I use green lentils and soak overnight, is it 150g measures when dried and unsoaked? Thanks !
Shevy (Slimming Eats) says
no need to soak the lentils overnight, green or brown are fine. If you do prefer to soak, I recommend weighing before soaking.
LRV says
Just made this recipe. Really delicious and very filling. Added some chopped mushrooms near the end and a few drops of Worcester sauce. Delicious!
