I find the lentils take almost a hour to cook through, after 25 minutes they are still hard as rock??? Am I doing something wrong? Still delicious in the end, just take alot longer!!
I’m sorry, I wish I knew. They shouldn’t have taken that long. I’m am trying to think of why they would have taken that long.
The perfect cold-weather meal. Another great soup recipe, thanks!!
I have never tried lentils. Your recipe looks yummy. Is this spicy with the cajun seasoning, black pepper and 2 kinds of paprika? I don’t handle spicy very well. Would you suggest that I make an adjustment to the seasonings?
I am so excited about this recipe !!!!’ I love in Montana and it is certainly brisk now so perfect soup for today . It’s a plus that you have the Dutch oven recipe as it’s my favorite thing in the world to cook with!!! I stumble across your site on Pinterest looking for a cleaning checklist which I still haven’t found because I got side tracked with all the yummy recipes.
can you tell me how to make this recipe with out an instant pot?
It would be the same method, just on the stovetop in a large stockpot or Dutch oven. I generally simmer it all for 25 minutes. Hope that helps!
