    Are you ready for an amazing sweet potato side dish? You're going to love these Rosemary Garlic Smashed Sweet Potatoes! While mashed potatoes and mashed sweet potatoes are both traditional holiday side dishes, these crispy smashed sweet potatoes make a nice change!

    ❤️ Why you'll love this recipe

    • Oven-roasted. Perfect for Thanksgiving or any holiday meal, these smashed sweet potatoes caramelize and brown as they roast in the oven.
    • So much flavour! They're drizzled with a flavourful rosemary garlic butter, topped with fresh cracked pepper and Parmesan cheese then returned to the oven to become perfectly browned and crispy.
    • An easy-make ahead savory side dish. Mashed sweet potatoes are a popular holiday side. I've never been a fan of sweet potato side dishes topped with marshmallows. Savory sweet potato recipes have always been my favourite, as sweet potatoes are naturally sweet.
    • One pan meals are life-savers, especially for holiday dinners. These Italian-inspired sweet potatoes are cooked on one baking sheet. Minimal clean-up. No boiling required!
    • No need to boil first! Not only does roasting the potatoes add more flavour and texture, it eliminates the need to boil the potatoes first, which can result in overcooking and the risk of having the potatoes fall apart.

    I make these Make-Ahead Duchess Sweet Potatoes for special dinners, and these Baby Hasselback Sweet Potatoes whenever I can find those baby ones in the supermarket. Smoky Sweet Potato Wedges are my choice to serve with burgers.

    But are you ready to make one of the best savoury Thanksgiving sweet potato side dishes?

    🛒 Ingredients

    • sweet potatoes:  medium sized. Leaving the skins on adds nutrition and fiber and prevents the sweet potatoes from falling apart.
    • olive oil: for even browning and a crispy exterior
    • butter: for amazing flavour
    • garlic: because . . .  garlic!
    • rosemary:  to infuse the butter with wonderful herb flavour
    • Parmesan cheese: makes a crispy, chewy topping
    • Italian herbs:  thyme, oregano, parsley for garnishing

    How to make smashed sweet potatoes

    1. Begin by cutting the sweet potatoes into rounds approximately 1 inch thick. Cut them all the same size so they cook evenly.
    2. Toss with olive oil, season with salt and pepper and roast in the oven until fork-tender.
    3. While they're roasting, heat butter and cook gently with garlic and rosemary to make herb-infused garlic butter.
    4. Remove the sweet potatoes from the oven, smash with the base of a drinking glass, then drizzle with the rosemary-garlic butter.
    5. Top with more freshly cracked pepper and Parmesan cheese and return to the oven to melt the cheese and crisp the edges.
    6. Garnish with fresh herbs and serve hot!
    • Two medium sweet potatoes and a knife
      1. Slice into rounds 1 inch thick.
    • smashed sweet potatoes ready for the oven
      2. Roast in the oven.
    • rosemary garlic butter in a saucepan
      3. Make herb-infused garlic butter.
    • Baked Smashed Sweet Potatoes on baking sheet
      3. Smash and drizzle with rosemary-garlic butter.

    👍🏼 Tips and FAQ's

    What's the difference between mashed sweet potatoes and smashed sweet potatoes?


    Mashed sweet potatoes are boiled, then mashed or pureed with butter and milk to make a creamy side dish. Sometimes they're topped with brown sugar or marshmallows. Smashed sweet potatoes are roasted, then gently pressed and topped with butter or sometimes cheese before being returned to the oven. They have a crispy texture.´

    What's the best way to smash a potato?

    Gently pressing down with the base of a drinking glass works well for me. You want to squash them until they are about ¾ inch thick, so they will become crisp in the oven. Don't worry if you smash them too thin or if they don't end up in perfect rounds! They'll still be delicious!

    🔁 Possible variations

    Besides drizzling with rosemary-garlic butter, you can add extra toppings to these smashed sweet potatoes.

    1. You'll make a whack of new friends when you bring a tray of these to a potluck topped with crumbled bacon bits.
    2. Add thinly sliced green onions or chives.
    3. Add thin strips of prosciutto before putting back in the oven. Crispy prosciutto adds a ton of flavour!

      I have three things: a fondness for sweet potatoes, a deep love of garlic, and a ridiculously oversized rosemary bush. Needless to say, these are calling to me! I really like the way you've prepared these as rounds too - it's not something I normally do with sweet potatoes, but it's a great way to serve them and speed up cooking. Plus, more surface area for crisping!

      I love these! I'm a big fan of sweet potatoes, and the garlic butter, rosemary, and parmesan only take them up a notch. They're much better than marshmallows!

      I'm so with you on the marshmallows. I think sweet potatoes are sweet enough already, and I love the additions of rosemary and garlic. Pinning to try!
