This simple slow cooker lentil soup is flavored with tart apple and hearty smoked sausage, and finished with a little sour cream and mustard. If you don’t have time to sauté the onions and apples, you can skip that step, going straight to Step 2 and putting the ingredients directly into the slow cooker. Small green lentils (also called French lentils or lentils du Puy) have a peppery flavor and keep their shape when cooked instead of falling apart, giving the soup an appealing texture. However, you could also use black lentils or easier-to-find brown lentils, but keep in mind that brown lentils will fall apart as they cook, creating a thicker stew. (Here is the stovetop version of this soup.)

Preparation

  1. Step 1

    Melt the butter in a large (12-inch) skillet over medium-high heat. Add the onion, season with salt, and cook, stirring, until the onion is translucent, about 5 minutes. Add half the diced apples and cook, stirring until softened, adjusting the heat as necessary to avoid scorching, about 5 minutes. Add the celery, garlic, sage and thyme, and stir to combine. Pour in the cider and let it come to a bubble. Scrape the mixture into a 6- to 8-quart slow cooker.

  2. Step 2

    Add the sausage, lentils, nutmeg, 1 teaspoon salt and a generous amount of black pepper to the slow cooker; pour in 3 cups water. Cover and cook on low until the lentils are tender and the flavors are mellowed and blended, about 8 hours. The soup holds well on the warm setting.

  3. Step 3

    Just before you are ready to eat, add the vinegar. Stir together the sour cream with the mustard, then stir the mixture into the soup. Taste and add more salt and pepper if necessary. Serve in bowls topped with the scallions and remaining chopped apple.

Tip
  • Any sparkling or still dry hard cider works well in this recipe. In a pinch, you can substitute dry white wine and mix in a few spoonfuls of apple juice, if you have it. For a nonalcoholic option, use chicken or vegetable stock, but increase the vinegar a bit at the end for tartness.

Cooking Notes

This soup was very good with an interesting complexity of complimentary flavors. But it required a LOT of prep time--get up early! I'm eating it for dinner. Used plain brown lentils, and it was fine. Chop only ONE apple as you prep your ingredients: otherwise, your other chopped apple will have to sit in the fridge all day.

This recipe is so hearty and satisfying in the winter. I’ll be honest, I skipped the prep cooking and just chopped and threw everything in the slow cooker. It’s delicious.

The cider in this soup is hugely aromatic and flavorful and lasted through the week as I ate leftovers for lunch. I used a local Chicago brand, Right Bee. This soup was so flavorful that since I had leftover cider I am making it again. I already love lentils and lentil soup, and this recipe took the flavors over the top in a positive way. Highly recommended: make this soup while apples are in season!

A cup and half is definitely not enough liquid. I probably added another 2-3 cups of water and broth to even have the lentils covered, and over the course of cooking almost all of that liquid evaporated out. Good soup though!

This was actually quite a lot of work for a slow cooker recipe. I found myself scrambling to chop and sauté the apples and onions to get it in the Crock-Pot at a reasonable hour. I used double-smoked kielbasa sausage from a Polish market and served it with crusty French bread and stuffed cabbage. In the end, it was a hearty and tasty meal, but my spouse and I didn’t feel there was much flavor there. I would not make this again.

I didn’t have time to prep in the morning, so I opted to use my instant pot instead. I used the sauté function at the beginning, then cooked for 25 minutes on high pressure. The soup turned out perfectly, very flavorful!

I live at 7500 ft and cooking any kind of legume is difficult to get to a softened stage on the stove top and have to use a pressure cooker. I cooked this on the hi setting for 15 minutes and then allowed a gradual release. I followed recipe as written, with the exception of chicken broth instead of water and one bunch of kale for some greens. This recipe is excellent and may be my new lentil one pot go to meal for a while. A keeper for sure.

I made this with Field Roast Smoked Apple and Sage vegetarian sausage, and it was delicious! I cooked it in the slow cooker on high. It was done in about 3-3 1/2 hours. I left it on “keep warm” for a couple more hours, but should have added more water. Definitely a keeper for me!

The additions of apple juice/wine and all the add-ons in Step 3 elevated my usual lentil soup to a revelation of Oh My! Didn't know it could be this awesome! I'll be sure to get some apple cider next time. Can't wait.

I thought this turned out great. I used a chicken andouille sausage. I omitted sage due to a lack of any in my pantry, used allspice in place of nutmeg, added a dash of cumin, and used two cups of chicken broth and one cup of water instead of three cups of water. Very tasty. I also paired the soup with a Ginger-Scallion Steamed Mahi-Mahi (recipe by Connie Chung, adapted by Ali Slagle on NYTCooking). Everything was very satisfactory. The soup is being added to the rotation.

Echoing the need for significantly more liquid. Everything across the surface was burnt black when I got home. But mixed all together it was still tasty.

This was great! Used black lentils and Firld Roast vegetarian apple-sage sausages in place of the andouille. Also subbed white for black pepper because I thought it married well with the nutmeg. My only comment is that there isn't nearly enough liquid in the recipe as written. But that's an easy fix!

The flavors on this are lovely—hearty but not overpowering. I got a late start on this so I cooked on high for 2hrs and then low for 4 more. Don’t skip the garnishes, they add a really nice fresh lift to the end result.

The finished soup was flavorful and delicious. A possible amendment would be to add some Worchester, or some anchovy paste to deepen the flavor profile. While it had sharpness, it lacked depth. To make it more of a stew, I added cubed avocado and croutons. I intend to experiment with making this into pot pie, as I think it benefits from something crusty. Alternately, I'll serve it with a crusty french bread.

We used vegan Italian sausage and found that the flavor overwhelmed any other flavor nuance in the soup. It was certainly hearty and satisfying, but I would try a less flavorful sausage next time in hopes of tasting the other layers.

Three cups of water is way too much and will turn this soup into a bland bouillon. One cup will do.

Tasty, though it takes a long time to cook the actual prep was quick and easy. I liked it a bit better before putting the vinegar sour cream and mustard in it before serving. Next time I might skip or use 1/2 the recommended amount of these last ingredients.

We loved this! Used a spicier vegan sausage, red lentils, skipped the sour cream (dairy allergy), kept the mustard. Accidentally added both apples at the beginning. I was worried bc didn’t have time to sauté anything - just dumped it all in the slow cooker - and used veggie broth bc I didn’t have cider. Maybe the extra apple made up for the cider? Anyway we loved it!

Loved it, but am going to try with red lentils next time.
