Common questions about this red lentil curry

Can I use green or brown lentils instead of red?

Red lentils are best here as they break down into a thick, creamy base within 15–20 minutes, while still providing plenty of iron from a plant-based source. Green or brown lentils will give a different texture as they hold their shape and take longer to cook, so if using them, add extra stock and simmering time.

Is this curry freezer-friendly?

Yes, it freezes very well for up to 3 months. The texture holds up better than most curries thanks to the lentils, though spinach may soften slightly further on reheating.

Can I make this curry less spicy for children?

Yes, simply reduce the Thai red curry paste to 2–3 tablespoons, or use a mild curry paste instead.

What can I use instead of coconut milk?

A single or half-fat coconut milk works for a lighter version, or use coconut cream diluted with vegetable stock if you prefer an even richer sauce.

    Wow.. your recipes are just the bomb!
    So easy, so tasty. I feel so many others are afraid of all the spices and so their recipes end up tasting just bland but yours.. wow. Absolutely amazing!
    So grateful I found your blog because I’ve never made so many recipes by one creator! Love them!
