  1. I made this tonight and it is very good… I could not find any curry paste so I just added 2 tsp curry and it's good too…

  2. I made this and it was really good… I turned the crock pot off for an hour while I went to the gym… OMG it was DELICIOUS when I cam back home from a good workout! I put it on a bed of brown rice…

    1. Jamie, Yes, cool this to room temperature and place in an airtight container to freeze. This should last in the freezer for 4 months.

        1. llyse, Allow it to thaw enough to remove it from the container, and then place in a partially covered heavy bottomed pot on the stove top over low to medium low heat. Enjoy:)!

  3. Does this really make 8-10 servings. Planning to make it for friends and there will be 6 total. Wondering if I should double it?

    1. Katie, Yes, but the servings are smaller. If you're making it for a gathering where guests will probably eat larger servings, I would double it. You can always freeze or refrigerate the leftovers.

  4. Hi! I want to make this during the week, but don't have a timer on my crockpot or six hours when I get home from work in the evening. Can it be cooked on high for less time? Thanks!

    1. Anne, You can cook this on the stovetop in 1-1/2 hours or leave it in the slow cooker for 8 hours on low.

  5. I am so glad I tasted and cut the red curry paste in half before adding it to the mix, because 3tbsp would have been way too spicy (and I eat a lot of spicy food). Next time I make this recipe, I'll be cutting down on the paste even more. Perhaps the red curry paste I picked up at the Thai grocery store is spicier than what's in a regular grocery store? (The brand is Mae Ploy). Anyway, may be a good idea to have folks taste the paste for spice level before adding it to the mix. I've seen other recipes call for 5tbsp, and I'm just like "nope."

  6. I am making this now and adding chicken to up the protein. Thank you soooooo much for my my food life more tasty! ?????

  7. Hi! I’m experimenting with lentils in a bolognese sauce in the crockpot. I used 1 cup of lentils and 1 3/4c water on low for 6 hours. My lentils are still crunchy and the time is almost up. Do you have any suggestions?

    1. Oh dear, I’m guessing the recipe is done? Lentils generally only take about 20 minutes to cook on the stove top and no more than a few
      hours in the slow cooker. How long did you have to cook for?

  8. I’ve made this recipe 3 times and I love it! I serve it with basmati and green onions or cilantro. I add a little bit more coconut milk than it calls for but follow everything else exactly. It freezes well so my household of 3 gets 2 meals out of the recipe. Thank you!

  9. Stumbled upon this recipe looking for slow cook lentil recipes. It. Is. AMAZING. Proper 9/10. I didn’t add the coconut milk (as i didn’t have any) but followed it apart from that and we just ate it with a naan. Will definitely be making a massive batch next time I have people round. Great sharing dish. Thanks for this. Bookmarked!

  10. I made this today and we all loved it! I did add some cooked chicken, cut up. I don’t think anything else is needed (like Rice) it was very filling and flavorful! Thanks!
