Crunchy Mexican coleslaw with a kick from jalapeño-infused avocado oil, lime zest, and cumin. 3.4g net carbs per serving. I toss it with fresh cilantro and red onion for a side that works with tacos, fish, or grilled anything.
Most coleslaws are an afterthought, something you grab from a deli tub and forget about. I wanted a slaw that actually earned its spot on the plate, and the answer turned out to be jalapeño-infused avocado oil. That one technique is what separates this from every pre-made version I’ve tried.
Here’s what I do: instead of mixing raw jalapeño into the salad, I let sliced jalapeño steep in avocado oil with lime zest, garlic, and cumin for at least 30 minutes (overnight is better). The oil pulls out a slow, warm heat that’s nothing like biting into a raw pepper. The lime zest is what gets people. Most coleslaws just use juice, but the zest is where the real citrus flavor lives. I didn’t figure that out until I accidentally left it out once and the whole batch tasted flat.
I serve this mexican coleslaw alongside cilantro lime chicken, piled on fish tacos, or next to grilled vegetables at cookouts. It pairs with practically any protein. My favorite combo is a big scoop of this slaw on top of a taco salad or served alongside grilled bacon burgers when we have people over.
The whole thing takes about 10 minutes of active prep. Toss a bag of coleslaw mix with red onion, fresh cilantro, and that infused dressing, and you have a keto side dish that holds its crunch for days. I’ve brought this to three cookouts now, and every time my bowl comes back empty before anything else on the table gets touched.
One thing I learned after making this dozens of times: the jalapeño keeps releasing heat into citrus-based dressings. By day three, leftovers are noticeably spicier. If you’re prepping for the week, pull the jalapeño out after infusing or cut the amount in half. The flavor stays, just without the creeping heat that surprises people.
At roughly 3.4g net carbs per serving, this is one of the easiest low carb sides I keep in rotation. No cooking, no heating up the kitchen, just sharp flavors and good crunch.
How to make it creamy
The base recipe is dairy-free on its own, but I’ve made creamy versions plenty of times when I want something richer. All you need is 1-2 tablespoons of one of these stirred into the dressing:
Greek yogurt (my favorite for a keto creamy slaw, adds tang without heaviness)
Sour cream
Mayonnaise
I usually go with Greek yogurt because it blends into the lime dressing without masking the jalapeño. Sour cream works too, it’s just a little heavier. Mayo gives you that classic creamy coleslaw texture if that’s what you’re after.
Ways I switch it up
I’ve tried a lot of swaps over the years. Here are the ones that actually worked:
Jicama or radish for extra crunch. I slice jicama thin and toss it in with the cabbage. It stays crisp even after sitting in dressing overnight.
Apple cider vinegar in place of some of the lime juice if you want a sharper, less citrusy tang. I use about a tablespoon.
Taco seasoning or adobo sauce instead of cumin for a different spice profile.
Shred your own green, purple, or red cabbage instead of the bagged mix. I prefer purple for the color contrast.
Swap red onion for green onion, red bell pepper, or celery if raw onion is too strong for you.
Skip the jalapeño entirely if you don’t want any heat. The lime and cumin dressing still holds up on its own.
Refrigerate: I keep leftover slaw in an airtight container for up to three days. The cabbage softens slightly by day two but still has good crunch if you used fresh-shredded.
Make the dressing ahead: I make the jalapeño-infused dressing up to a week in advance and store it separately. When I’m ready, I pour it over fresh coleslaw mix and toss. Keeping the dressing separate works best for meal prep because the cabbage stays crisp until you’re ready to eat.
Watch the heat: If you leave the jalapeño in the dressing for more than a day, the spice builds. By day three, it’s noticeably more intense. I pull the slices out after the initial 30-minute infusion when I’m prepping for the week. The flavor stays without the escalating heat.
What goes into this jalapeño lime slaw
These ingredients come together into a bright, tangy cabbage salad with a homemade dressing that takes about two minutes to stir together.
Avocado oil: I use avocado oil because it has a clean, neutral taste that lets the lime and cumin come through. It's the base of the infused dressing.
Jalapeño peppers: I keep the ribs and seeds on for maximum heat. The whole slices steep in the oil and get pulled out before tossing, so you get warmth without chunks of pepper in every bite.
Garlic, minced: One clove, minced fine. It mellows as it sits in the oil.
Lime zest and lime juice: Both. I can't stress this enough. The zest carries the real citrus punch; the juice adds the acid that softens the cabbage just enough.
Cumin: Half a teaspoon is all you need. It adds warmth without making this taste like a spice blend.
Coleslaw mix: A 14 oz bag works, or shred your own cabbage. I've started using fresh cabbage because it holds its crunch longer, especially when making this ahead.
Red onion, thinly sliced: Thin slices, not diced. You want ribbons that weave through the slaw.
Cilantro: A full cup of chopped cilantro stirred in right before serving. It wilts fast, so I always add it last.
How to make this cilantro lime coleslaw
There are only a couple of steps, and most of the time is hands-off while the dressing infuses.
Make the dressing: Add avocado oil, jalapeño slices, garlic, lime zest, lime juice, ground cumin, and salt to a small bowl. Stir it together.
Let it infuse: Cover and refrigerate for 30 minutes minimum. I usually make mine the night before and let it sit overnight. The longer it sits, the more heat the jalapeño releases.
Toss: Pull out the jalapeño slices and pour the dressing over coleslaw mix in a large bowl.
Finish: Add sliced red onion and cilantro, toss once more, and serve.
Add avocado oil, jalapeno slices, garlic, lime zest & juice, ground cumin and salt to a small bowl. Stir and let sit for 30 minutes or overnight to allow time for flavor from jalapeno to infuse into the oil.
For this step

1 garlic, minced
1 tablespoon lime zest
2-3 tablespoons lime juice
½ teaspoon ground cumin
½ teaspoon salt

Frequently Asked Questions
Can I use this Mexican coleslaw on tacos?
Yes, and it's my favorite way to use it. I pile it on grilled fish tacos, shrimp tacos, and pulled pork tacos on taco night, and I wrap it in keto tortillas with grilled chicken. The lime and cilantro in the dressing already match those flavors, so toss it right before serving and it stays crisp on the shell.
Can I use serranos instead of jalapeños?
I've tried both. Serranos are sharper and the heat hits faster, while jalapeño gives a slower, gentler warmth. If you like that kind of immediate kick, go for it. I'd start with 15-20 minutes of infusion instead of the full 30 since serranos release heat quicker into the oil.
Is this recipe Whole30 or paleo compliant?
Yes, as written. Avocado oil, jalapeño, garlic, lime, cumin, cabbage, red onion, and cilantro are all Whole30 and paleo approved, and the base dressing has no dairy and no sugar. Skip the Greek yogurt, sour cream, or mayo from the creamy version if you're keeping it Whole30. I've served this at dinners where half the table was paleo and nobody needed to modify anything.
I’ve made this a few times and the jalapeño oil does something vinegar dressings just can’t. Quick heads-up: raw garlic hits pretty sharp if you dress it right away. I let it sit about 10 minutes before serving now and the bite mellows out a lot. Everything else is right on, the lime zest especially.
Cut the red onion to about two tablespoons. I used the full quarter cup and the raw sharpness competed with the jalapeño oil rather than letting it shine. Lime zest and cumin are right though. That one change and this slaw is exactly what I wanted.
9.4g fat, all from that jalapeño oil, and somehow the cumin and lime zest land exactly like the coleslaw my mom used to make for carne asadas. Close enough that it actually got to me a little. Just grateful this recipe exists.
Confession: been stuck on the same creamy keto slaw for taco nights. Tried this with grilled fish and the avocado oil dressing keeps the cabbage way crunchier than mayo ever does. Not going back.
I used to make coleslaw for every taco night before I started keto, and then just stopped because it felt like one more thing to figure out. Made this last week with the jalapeño-infused avocado oil and the lime zest, and it hit exactly the way I remembered. Not a keto-consolation version, just coleslaw that actually tastes good. Really glad this one exists.
Ha. Smart kid. I pull mine out so the heat stays dissolved in the oil rather than biting into a whole slice, but he’s not wrong, those jalapeños soaked in avocado oil and lime zest are worth eating straight.
Tip for anyone who wants more jalapeño heat: leave the slices in the dressing for a few extra minutes before tossing. The oil picks up noticeably more kick. I usually prep the dressing while I slice the onion and cilantro, so by the time everything’s ready the infusion has had a solid 10-15 minutes. Makes a difference.
Left the jalapeño in the oil longer than the recipe says on my second batch, around 20 minutes, and the heat level jumped noticeably. Now I pull it at about 8 minutes when I’m making it for people who can’t handle much spice, leave it in longer when it’s just for me. Also tried thinly sliced napa cabbage instead of the bag mix and it held up better to the dressing, less waterlogged after sitting for an hour. The lime zest is doing more than I expected, almost worth zesting two limes if you’re into that brightness. Would bump the cumin up to 3/4 teaspoon next time, but that’s a small thing.
I made this on Friday to go with fish tacos and my husband, who picks cilantro out of literally everything, went back for more without saying a word about it. I kept waiting for him to push it around his plate. The lime zest must be doing something because it just tasted light and fresh instead of overwhelming, even with a full cup of cilantro in there. I’d never infused oil before and wasn’t totally sure I was doing it right, but you basically just let the jalapeno slices sit in warm oil for a few minutes and that’s it. Made the whole batch and there was nothing left by the end of dinner, which never happens with coleslaw at my house. Already putting it on the list for next taco night.
The lime zest does that. Without it the cilantro can go soapy. A cilantro skeptic going back for seconds without saying anything is better than any review.
Almost skipped the jalapeno thinking it’d be too spicy. It’s barely hot, just a little warmth in the back. Every store-bought coleslaw tastes flat after this.
Never made coleslaw from scratch before, always grabbed the bagged premade stuff. Made this for taco night last week and the lime zest in the dressing completely floored me. I stood at the counter eating it before I even finished plating dinner. One question: can I make the dressing a day ahead and just toss it right before serving, or does it need a little time to marinate together?
Yeah, make it ahead. The lime zest and cumin need a little time to settle anyway, so overnight is actually better. Just toss right before you serve so the cabbage stays crisp.
I’ve made this for years with mayo and lime, so I was skeptical an oil-based dressing could hit the same way. But avocado oil with cumin and lime zest (not just juice) does something unexpected. Brighter, lighter, less cloying. My old recipe is officially on pause.
This holds up for four days in the fridge if you wait to toss the dressing right before eating. Pull the jalapeno back to half if you’re prepping for the week since the heat builds by day three. Good enough to keep on rotation, just needed that one tweak.
Keep the dressing separate and it holds fine. The jalapeño keeps releasing heat in citrus-based dressing so by day three you’re getting twice the bite. Half makes sense for anything you won’t eat that day.
Made this on a Tuesday to go with chicken thighs and my youngest, who normally just pushes coleslaw to the side of her plate, was asking me what was in the dressing before she even finished her bowl. She’s not a person who notices food, so that stopped me. Something about the lime and that gentle heat from the jalapeno gives it this brightness I wasn’t expecting from a slaw, especially in the middle of winter. Going in the rotation for taco nights.
A kid asking what’s in the dressing before she’s even done. That’s the one. The jalapeño in this reads as brightness more than heat, which is why it surprises people. Taco nights are the right home for it.
