Reese Witherspoon’s Slow Cooker Lentil Soup: Great for Winter, Needs *These* Toppings

Reese Witherspoon’s been known for introducing the masses to the next it book, but it turns out she’s also ahead of the game when it comes to food trends. Fibermaxxing—aka getting in the recommended 25 grams for women, 38 grams for men each day—may be all over Instagram today, but she’s been (perhaps unintentionally) advocating fiber-rich meals since 2021.

You see, back in the late-stage pandemic era when we were all pretending to be Ina Garten on social media, Witherspoon shared a lentil soup recipe, and it really took off. The slow cooker concoction called for roughly 11 ingredients, and it didn’t provide measurements or directions, but that didn’t stop people from guesstimating, riffing and making their own versions, just because it sounded so hearty, healthy-ish and simple. (On the fiber front, the lentils alone provide 31 grams, along with a solid amount of protein, iron and vitamin B6.)

Admittedly, I was equally intrigued, so after seeing our former food editor’s approximation of the recipe, as well as others online, I decided to try it myself. It turns out, it’s the cold-weather staple I never knew I needed—and I bet you didn’t either (until now).

How To Make Reese Witherspoon’s Slow Cooker Lentil Soup

Essentially, you’re chopping up a mirepoix of carrots, celery and onion, sautéing them, and adding them to a slow cooker with rinsed green lentils, vegetable stock, garlic and a host of seasonings. Simple—yet I still uttered a minor groan. Sautéing? So I need to dirty a frying pan first?!

When it comes to slow cooker meals, I am lazy. I want to dump things in that Crockpot and let the machine work its magic. But, in the interest of channeling my inner type-A Elle Woods, I heeded her instructions. Even when she went rogue—and in that instance, I took some creative liberties too.

“OK, I also decided to add a little bit of sausage, so who knows, man? I’m just going off recipe,” she says in the Instagram video. “We’ll see how it turns out.”

From there, the screen flashes to an empty bowl, devoured so quickly she never got footage of the completed soup. That was enough of a sign to me to add sausage.

In this case, I browned mild Italian sausage first, seasoning it with the same seasonings Witherspoon uses in her soup—cumin, ground coriander and paprika. I used the leftover grease from the sausage to sauté the carrots, onion and celery, infusing them with a stronger savory flavor and letting them caramelize. This extra step was well worth it—it gives the soup a richer, more complex flavor, otherwise it tastes like a mild bean stew.

From there, all of the ingredients were dumped into the slow cooker and set to low for the next 6 hours.

The Verdict: It Needs a Toppings Bar

The one measurement Witherspoon specifically provides is two cups of lentils. Based on that, most recipes recommend 8 cups of vegetable stock (or you could do 6 cups vegetable stock, 2 cups of water), though the end result is less of a soup, more of a chili-like thickness. It makes for an incredibly hearty meal, though if your slow cooker is big enough, you may want to boost the vegetable stock by 2 more cups for a more soup-like consistency.

The sausage adds a meatiness that makes the lentils taste more robust, and the dish is well balanced, without skewing too salty. It’s very much like a mild chili, honestly, so anyone looking for a little zing may want to add a squeeze of lemon juice or a dash of hot sauce.

I recommend serving it with a toppings bar, letting people customize it as they see fit. Some sour cream, grated Parm or shredded cheese, sliced chives or crumbled tortilla chips could all be nice additions, just to take things to the next level. (My husband liked the flavor, but wanted a little crunch or textural variety, hence the crumbled chips.) Heck, I've even swirled in a spoonful of Good Foods Cucumber Feta dip for a briny, creamy twist. (It was excellent, BTW.) But it’s pretty satisfying served as is with a hunk of crusty bread for dipping.
