These potatoes saved me on more than one chaotic evening when Ellie would not stop asking for snacks and I had nothing planned. I made this smashed sweet potato dish with what was in the pantry and it turned into a family favourite almost by accident.
The real game changer is the garlic parmesan smashed sweet potatoes: that garlicky butter slips into all the little cracks and the parmesan goes golden and salty on top. It pulls the whole thing together without any fuss.
You boil until fork tender, you smash gently so they keep some shape, then you broil until the edges get seriously craggy and good. It is simple. Really simple.
Preheat the oven to broil.
Place the sweet potatoes in a large pot of salted water and bring to a boil. Cook, covered, for 20 to 25 minutes or until just fork-tender, then drain well.
Arrange the sweet potato pieces on a large, lightly greased baking sheet. Using a fork, lightly flatten each piece, being careful not to press too hard, as this will cause them to break.
In a small bowl, mix together 3 tablespoons melted butter, 4 minced garlic cloves and 1 tablespoon fresh chopped parsley.
Pour the prepared garlic butter mixture over each sweet potato. Sprinkle with salt and black pepper, and lightly spray the tops with olive oil.
Broil the sweet potatoes until golden and crispy, about 15 minutes.
Remove the baking sheet from the oven, sprinkle over the shredded Parmesan cheese and return to the oven until the cheese has melted.
Sprinkle with a little extra salt and fresh chopped parsley, and serve right away.
Large pot for boiling, a colander for draining, a fork for smashing or a potato masher if you prefer, and a rimmed baking sheet. Line it with parchment if you do not enjoy scrubbing later. A small bowl for the garlic butter, a sharp knife and cutting board for the garlic and parsley, and oven mitts. I often lay everything out because cooking with a toddler underfoot is a performance art.
Oh and a quick note: if your broiler is temperamental like mine, do a quick test first so you do not get surprises. Trust me.
Right, let us talk technique. Pick medium to large sweet potatoes with smooth skins so they boil evenly. Tiny ones can overcook and go mushy, and that is not fun. I learned this the hard way.
Salt the boiling water like you mean it. My mum used to say the same thing about her bread at the bakery: you have to salt early to wake the flavour up. It helps the potatoes taste like themselves, not just like plain starch.
When you smash, press gently so you get those crispy bits. The butter and garlic pool in the ridges and then toast under the heat. Do the butter first: melt the butter, stir in the minced garlic and parsley while it is warm so the garlic loses that sharpness and becomes mellow. Broil but keep an eye on them; fifteen minutes can become charred in a blink. Actually, scratch that. Peek early and often.
This is also a solid healthy potato recipe because you are not deep frying. You get the texture without a lot of oil. If you want them lighter still, use a little less butter and a bit more herb.
Add chopped rosemary or thyme with the parsley so the herbs crisp up under the heat and cut through the sweetness. If you broil them longer the herbs will get slightly crisp and give tiny flavour bursts.
If you have people who like a bit of a kick, sprinkle chili flakes or smoked paprika over them before the butter drizzle. It turns these into a proper crispy potato side dish with a warm aftertaste that plays well with the sweet base.
For full on comfort, add extra cheese like cheddar or a scattering of feta with the parmesan so it melts in gooey pockets. Ellie and I once tried this on a rainy afternoon and it felt like a tiny celebration in a bowl. For a lighter take, go low fat, but honestly the full fat sings louder.
Want those viral tiktok potatoes vibes? Make the smashing dramatic on camera and finish with colourful herbs or cheese shards. Ellie thought it was theatre, and the photos looked great. It is showy, but it still tastes like the same simple thing that saved dinner.
They are brilliant with roast chicken, or next to a fresh green salad tossed in vinaigrette. They hold up at barbecues beside burgers or veggie skewers and they are an excellent thanksgiving side dish that adds colour and texture to the table.
For small people, a dollop of sour cream or ketchup is never a bad idea. For grown ups try a herby yogurt dip or a scattering of chopped pecans for crunch. Or serve them with eggs in the morning; they soak up yolks nicely.
No broiler, no problem. Bake at 425 degrees Fahrenheit for about 20 minutes and flip halfway to get even crisping. It will not be exactly the same as broiled edges, but you still get golden texture.
Yes. Sweet potatoes have a natural sweetness that draws kids in, and the crispy bits make it fun to eat. If garlic is a problem, leave it out or make it milder. Let kids help smash and they will often eat more just because they were involved.
You can boil and smash up to a day ahead, store covered in the fridge, then finish with the butter and broil just before serving. Reheating fully assembled tends to soften the crisp, so finish at the last minute.
Make the smash satisfying on camera, add dramatic toppings, and capture the gooey cheese moment. It is fun, but flavour still matters. Keep the basics right and the rest is for show.
Definitely. It scales easily, pairs with turkey, and brings a fresher note to the usual spread. Make extras because they vanish fast.
Say goodbye to traditional mashed sweet potatoes. These Garlic Butter Smashed Sweet Potatoes boast a delightful contrast: the perfect combination of softness on the inside and crispy edges that add a wonderful texture. Did you make this recipe?
