Red Lentil Sweet Potato Curry with Tarragon


Serving up the best Red Lentil Sweet Potato Curry with Tarragon this weekend! I know what you’re thinking…not another red lentil curry recipe. But this delightful vegetarian main is not like the others. For one, we didn’t use red curry paste or coconut milk, we instead used a few classic Indian dried spices and vegetable broth. Second, ours gets tossed with fresh tarragon instead of cilantro. This lends a sweet and light licorice taste that pairs wonderfully with the spices. And third, we roast the vegetables for tons of flavour. All this adds up to a quick (45 minutes!) and healthy plant based meal!When we were doing a bit of research into making a red lentil curry, we noticed many recipes used red curry paste and coconut milk. Nothing wrong with that, we just didn’t want to put another recipe on the internet that was already done. So we decided on using a medium yellow curry powder, cumin and nigella seeds and left the coconut milk out entirely. Now if you’re like us, you may be new to nigella seeds, but don’t let that deter you from giving this a shot. We ordered ours online, through Jacobson’s (not sponsored, just sharing). The seeds have a somewhat toasted onion flavour, but with a herbaceous element, similar to oregano. A delightful flavour in curry – trust us.

Finally, the use of tarragon here may seem unusual. Our previous knowledge of tarragon was that it was common in French cooking, and that it had a licorice flavour. Which isn’t wrong, but definitely limited our understanding of how it could be used. I recently made a curried egg and cauliflower dish from Ottlenghi’s cookbook Simple, and it used fresh tarragon. I loved the flavour and couldn’t wait to use it again, and that’s coming from someone who hates black licorice (the red kind is okay).
