FAQs

Can I bake the sweet potatoes instead of grilling?

Yes. Roast them at 425°F (220°C) for about 25–30 minutes, flipping halfway, until tender and slightly crisp.

Can I make the yogurt sauce in advance?

Yes, the sauce can be made up to 3 days ahead and stored in the refrigerator in an airtight container.

Do I need to peel the sweet potatoes?

No, the peel is edible and adds texture and nutrients. Just scrub them well before cooking.

Can I use other herbs besides dill?

Absolutely. Try parsley, mint, cilantro, or chives depending on your taste preference.

Is this dish vegan?

It can be made vegan by using a dairy-free yogurt alternative.

What should I serve this with?

It pairs well with grilled proteins, veggie burgers, grain salads, or as part of a mezze platter.

How do I know when the sweet potatoes are done?

They should be tender when pierced with a fork and have visible grill marks or charring on the surface.

Can I use regular yogurt instead of Greek?

Yes, though the sauce may be slightly thinner. Strain it if you prefer a thicker consistency.

Will the sweet potatoes stay crispy?

They will soften slightly over time, but the charred exterior helps maintain some texture even after cooling.

Can I freeze leftovers?

It’s not recommended, as the sweet potatoes and yogurt sauce both change texture after freezing and thawing.
