A smoky, crunchy, creamy dip built for corn off the grillThis one belongs next to burgers and sausages
Some dips are there to cool things down. This one is there to pile on flavour. Grilled sweetcorn brings little pops of sweetness, jalapeño adds a green chilli edge, and mayo gives the whole thing a glossy, spoonable richness that feels right at home beside burgers, sausages and chicken. I make it when I want a dip that can double as a topping, because it’s just as useful dolloped into buns as it is scooped up with bread or crisp potatoes.
Sweetcorn gives texture as much as flavour
What I like most here is the bite. Once the corn has picked up colour on the BBQ, the kernels stay juicy but gain a slight chew and a whiff of smoke. That makes the dip feel busy in a good way, not flat and creamy from start to finish. It lands very differently from my fire-roasted red pepper feta dip for grilled spreads and it’s miles away from the smoother shape of a smoked tomato harissa Greek yoghurt dip. This one is chunkier, richer and made for messy BBQ plates.
Jalapeño and Cajun seasoning do different jobs
The jalapeño gives fresh, pointed heat, while Cajun seasoning rounds the dip out with paprika, garlic and savoury spice. I like that combination because it tastes lively without becoming muddled. If I’m after a sweeter chilli profile, I’d go for the mango habanero creamy lime dip instead. If I want smoke with a stickier feel, I’d put out the chipotle honey cream cheese dip from my BBQ dip collection. This bowl sits in a different lane, more picnic-table comfort, more crunch, more creamy swagger.
The sort of dip that disappears first
I’ve made this for enough barbecues to know what happens. It starts as a dip, then someone spoons it into a burger, then someone else adds it to a hot dog, and before long the bowl is scraped nearly clean. That’s why it sits happily in my guide to the best spicy BBQ dips to serve with grilled food. It’s practical, full of texture and exactly the kind of thing that makes plain grilled food taste more considered without any extra fuss.

Ingredient notes
Corn is the main event here, so I use fresh cobs when I can. Frozen corn works in a pinch, though you do miss the pleasure of blistering whole cobs over the grate and slicing the kernels off afterwards. Fresh corn has more bounce and sweetness, and once charred it brings a flavour that frozen kernels struggle to match. I grill the cobs until they’ve got dark freckles rather than full black patches, because I want sweetness first and smoke second.
Mayonnaise gives the dip most of its body, so I use a decent full-fat one. Sour cream lightens it slightly and adds tang, which keeps the finish from feeling greasy. Parmesan is a small addition, though it does useful work by adding savoury depth without making the dip cheesy in an obvious way. The jalapeño can be raw or lightly grilled first, depending on whether you want a fresher or softer heat. I like it raw here for contrast.
Equipment needed
You’ll want a BBQ with a hot section for grilling the corn and toasting the bread, plus a cooler edge if you’re also cooking sausages, burgers or potatoes at the same time. Tongs are essential for turning the cobs, and a sharp knife with a stable chopping board makes slicing the kernels off much easier once they’ve cooled a bit.
A mixing bowl is enough for the dip itself, which is one reason I like this recipe so much. No blender, no processor, no extra pan to wash up. A spoon or spatula will do the job. If you’ve got a wide shallow bowl for serving, use that. It shows off the corn nicely and makes it easier for people to scoop up plenty of kernels with each bite.
Instructions
Step 1, heat the BBQ
Set your BBQ for medium-high direct heat with a cooler section to one side. Lightly oil the grate if needed.
Step 2, grill the corn
Place the corn cobs over direct heat and cook for 10 to 12 minutes, turning every couple of minutes, until lightly charred in patches and tender.
Step 3, cool and slice
Move the corn aside to cool slightly. Stand each cob upright on a board and slice the kernels off with a sharp knife.
Step 4, prep the jalapeño
Finely chop the jalapeño. Remove the seeds and white ribs if you want a milder dip. Slice the spring onions and grate the garlic.
Step 5, mix the creamy base
In a bowl, stir together the mayonnaise, sour cream, lime juice, Dijon mustard, Cajun seasoning, smoked paprika, salt and black pepper until smooth.
Step 6, fold in the chunky bits
Add the grilled sweetcorn kernels, chopped jalapeño, spring onions, Parmesan and most of the coriander. Fold gently until everything is coated.
Step 7, let it sit briefly
Leave the dip for 10 minutes so the seasoning settles into the corn and the jalapeño mellows slightly.
Step 8, grill the dippers
Toast the baguette slices or burger buns on the BBQ. Grill the baby potatoes until crisp on the edges. If using lettuce leaves, char them very quickly for a little smoke.
Step 9, finish and serve
Spoon the dip into a bowl, scatter with the remaining coriander and serve with toasted bread, grilled potatoes and burgers or sausages if using.
Cooking technique notes for creamy Cajun sweetcorn jalapeño mayo BBQ dip
Corn benefits from proper contact with the grate. I don’t wrap it in foil for this recipe because steaming it would soften the kernels without adding the grilled character I want. Direct heat gives the corn a few blistered spots and keeps the kernels lively. Once cut from the cob, they hold their shape in the dip and provide that mix of sweetness and chew which makes the whole bowl more interesting than a plain creamy sauce.
The resting time matters too. Ten minutes might not sound like much, but it gives the Cajun seasoning a chance to bloom into the mayo and lets the jalapeño soften slightly without losing its freshness. Straight after mixing, the flavours can feel a bit separate. After a short pause, the dip tastes more coherent, and the sweetcorn seems to carry the spice better through each spoonful.
What to serve with this delish dip
This is one of the best dips in the set for burgers, hot dogs and sausages. It behaves almost like a relish, especially once spooned into a bun. I also love it with grilled baby potatoes, because the crisp outsides and fluffy middles work beautifully with the creamy sweetcorn. Toasted baguette slices are useful if you’re serving it as a proper dip, though lettuce leaves and grilled peppers make good lighter options too.
It’s also excellent with chicken thighs, pork chops and grilled halloumi. Because the dip is rich and textured, it suits simple, straightforward BBQ mains rather than anything already drowning in sauce. I think that’s why it disappears so quickly. People find ways to use it beyond dipping, and suddenly the bowl has become part condiment, part side dish, part excuse to eat another sausage.
FAQ
Can I use tinned or frozen sweetcorn in Cajun corn dip?
Yes, though fresh grilled corn gives the best texture and BBQ flavour. If using frozen, thaw it fully and grill it in a basket or pan until lightly charred.
How spicy is Cajun sweetcorn jalapeño dip?
It’s mild to medium in my version. The mayo and sour cream soften the jalapeño nicely.
Can I make sweetcorn mayo dip ahead of time?
Yes. Make it a few hours in advance, keep it chilled and stir before serving. Add the final coriander just before it goes on the table.
What can I use instead of jalapeño?
Try green chilli for more heat, or mild green pepper for a gentler version with no real kick.
Is this dip good on burgers?
Very. It works almost like a creamy corn relish and is especially good on beef burgers and hot dogs.
Why add Parmesan to a corn dip?
Parmesan adds savoury depth and helps the creamy base taste fuller without needing loads more seasoning.
Can I make this without mayonnaise?
You can use all sour cream or Greek yoghurt instead, though the finished dip will be tangier and less rich.
Tips for success with creamy Cajun sweetcorn jalapeño mayo BBQ dip
The key to creamy Cajun sweetcorn jalapeño mayo BBQ dip is getting proper colour on the corn without drying it out. I keep turning the cobs so they char in patches rather than burning in one strip. That way you get sweetness, smoke and juicy kernels all in the same cob. Once the corn is sliced off, don’t mash it or stir too aggressively. The shape of the kernels is part of the pleasure.
I also think it pays to be careful with the seasoning blend. Cajun mixes vary wildly. Some are salty, some are mild, some have loads of paprika. Start with a modest amount, mix, rest, taste, then add more if needed. That’s especially important if you’re serving the dip with salty grilled meats or bread, because the full plate can build in intensity very quickly.
Recipe variation suggestions
For a more street-food sort of feel, add extra lime zest, a touch more coriander and a spoonful of crumbled feta or cotija-style cheese on top. That takes the dip in a slightly elote-inspired direction without turning it into something else entirely. A little smoked chilli powder also works if you want the heat to feel deeper and more rounded than fresh jalapeño alone.
You can make it heartier by folding in diced grilled bacon, chopped charred red pepper or even black beans. That version is very good spooned into wraps with grilled chicken. For a fresher angle, use more spring onion and swap some of the mayo for Greek yoghurt. It won’t be quite as rich, though it makes a nice companion for lighter meats and a hotter afternoon.
Storage and reheating for creamy Cajun sweetcorn jalapeño mayo BBQ dip
Store leftovers in the fridge in an airtight container for up to 2 days. Because the dip is mayonnaise-based, I keep it well chilled and avoid leaving it sitting in the sun for too long at a barbecue. Stir it before serving again, as the dressing can tighten slightly once cold.
This dip is not for reheating. Serve it chilled or cool rather than hot. If it seems a little stiff from the fridge, let it sit out for 10 minutes and add a small squeeze of lime juice to freshen it up. Freezing won’t help the texture, so I’d avoid it.
Alternatives for dietary needs
For a lighter version, replace some of the mayonnaise with Greek yoghurt. For a vegetarian version, use a vegetarian Parmesan-style hard cheese. If you need it gluten-free, serve it with grilled potatoes, gluten-free buns or vegetable dippers.
For an egg-free version, use a good vegan mayo. You can also make the whole recipe dairy-free by skipping the Parmesan or using a dairy-free alternative and swapping the sour cream for a plant-based version. If you want less heat, reduce the jalapeño and let the Cajun seasoning provide most of the spice.
