This lentil and red pepper sauce recipe started off life as a soup, but by making it a little thicker, it makes a lovely, creamy sauce. It’s versatile and works well with pasta, made into a mild curry (with a few tweaks), or simply as a sauce to pour over your favourite protein and vegetables!

Nicky’s Recipe Notes
It seems to me that most sauces fall into 3 categories:
- Tomato-based and/or tangy/spicy
- Creamy and/or cheesy sauce
- Gravy
I’m a big fan of all three. This sauce though? I think it needs its own category. It uses red lentils for a velvety earthy flavour, plus red peppers and garlic for a fresh, fragrant hit. It’s all finished off with a little creme fraiche, just to add a little richness.
Keep a stash of it in the freezer and you can use it in so many ways!
