These grilled sweet potatoes with herbs have become my go-to whenever I need a colorful and healthy side dish that wins over everyone at the table. The herby yogurt sauce brings incredible freshness and pairs beautifully with the smoky charred edges of the potatoes. It is a recipe I reach for during BBQs and summer picnics when I want something that looks stunning and is just as easy to pull together.
When I first served these sweet potatoes at a family dinner my friends had never tried grilling sweet potatoes before and now they ask for them every time we cook outdoors together
Ingredients
- Sweet potatoes: Choose three medium ones that feel heavy for their size and look vibrant with no mushy spots The thickness of the cut gives that firm grilled texture with creamy insides
- Extra-virgin olive oil: For golden edges and a luscious mouthfeel go for a fruity fresh bottle if you can
- Kosher salt: A must for seasoning both potatoes and the tangy sauce It draws out natural sweetness and enhances every bite Maldon or Diamond Crystal brands work well
- Greek yogurt: Greek yogurt forms a velvety base for the dressing Use full fat for a rich taste and extra smoothness
- Green onions: These bring a mellow onion flavor without being too sharp I like to pick ones with strong green tops for more color and zip
- Fresh dill: Fresh dill adds an unmistakable burst of flavor plus extra for garnish makes the plate pop Choose dill that smells fragrant and has no wilted tips
- Garlic: Adds earthy depth A couple of cloves go a long way Look for bulbs that are plump and tight skinned
- Fresh basil: Basil gives a sweet peppery lift to the sauce Grab leaves that are bright green and not bruised
- Lemon juice: Fresh rather than bottled is best for zing Avoid lemons with dry or wrinkled skins

I absolutely love the contrast of smoky sweet potato with the cool tangy yogurt Dill from my garden is always my favorite touch and seeing my kids help with the garnish makes this dish extra meaningful for me
Storage tips
Keep leftovers in an airtight container in the fridge for up to three days Store the yogurt dressing separately if possible so the sweet potatoes stay firm If you see the sauce thickening after refrigeration a quick stir or dash of water brings it back to drizzling texture
Ingredient substitutions
If dill is out of season swap in flat leaf parsley or a mix of soft herbs like tarragon and chervil No Greek yogurt on hand Plain coconut yogurt makes this recipe dairy free and still delicious You can also use baby potatoes or Japanese yams instead of sweet potatoes but watch for cooking time changes
