Sounds lovely but concerned Cajun seasoning would make it inedible
for me as I am sensitive to too much pepper in anything
What other seasoning can I use as a sub?
Hi Rosalee, If you are sensitive to pepper I would omit the pepper and Cajun seasoning. There are other spices in the recipe that are more mild and it will still taste great!
Good, but unless you want it ready soupy, I recommend less broth., maybe 6-6 1/2 cups instead of 8. Everything just seemed to come together in like a puree, and I prefer a bit more substance.
This soup is amazing! We love lentil soup too particularly Indian Lentil Soup with Hot Homemade Naan. Since we live in “Cajun Country” we use a variety of Cajun seasonings but the overall favorite here in Lafayette Louisiana is Tony’s Chachere’s. It’s available at WalMart in huge supply and Amazon and many other grocery stores here. We never run out! Tony Chachere’s also makes a variety of dinner mixes which are quite good for a box dinner.
Reminded me of my grandmother’s Hungarian lentil soup, probably because of all of the paprika. So I gave it a couple of other Hungarian tweaks at the end by adding a splash of red wine vinegar and serving it with a dollop of sour cream. I’ve had three servings so far and I’m seriously tempted to have another.
Your additions sound delicious.
