21 Day Fix Skinny Smashed Sweet Potatoes 

Sweet potatoes are one of my favorite foods that I never actually make. Do you have any foods like this? Ones you love but never think to make? We don’t actually make any type of potatoes all that often. I usually reach for pasta or rice when I am putting together the starch component of our meal, but this side dish is so good and so healthy that I think I will have to add it to our normal repertoire!

When I do make potatoes, I usually make smashed potatoes (which is just my lazy version of mashed potatoes.) I normally use butter and milk to help moosh up my potatoes, but this time I decided to replace those with protein packed Greek yogurt. I was scared that this could end up in disaster, but after one bite, I knew I had stumbled on a winner! The yogurt made the potatoes creamy and tangy, which paired with a little agave nectar and cinnamon, was the perfect combination of tangy and sweet! These 21 Day Fix Skinny Smashed Sweet Potatoes are so good and are made even better because they are healthy and can be used for the popular diet, the 21 Day Fix by Beachbody.

Have you seen the sweet potatoes that you steam in the bag in the microwave?!

These have changed my life…seriously. If you see these at the grocery store, stock up! If you try these 21 Day Fix Skinny Smashed Sweet Potatoes, please let me know! And if you have other delicious Fix Approved recipes, please share them as well! I would love to have more in my arsenal!

As a mom who’s always searching for the perfect balance of healthy and hearty, skinny smashed sweet potatoes have quickly become one of my go-to side dishes.

What makes this dish so special is its versatility. With a few simple ingredients, you can turn these smashed roasted sweet potatoes into a savory, sweet, or spicy side dish that pairs beautifully with chicken, turkey, salmon, or even a plant-based main. Below are my favorite ingredient alternatives, optional toppings, and practical cooking tips that make this recipe even more adaptable—and more discoverable through Google search.

Ingredient Alternatives for Smashed Sweet Potatoes

  1. Sweet Potato Options
    Use classic orange sweet potatoes for their natural sweetness and soft texture. You can also experiment with:

  • Japanese sweet potatoes for a starchier, nutty flavor
  • Purple sweet potatoes for added antioxidants and a pop of color
  • Garnet yams for an extra creamy texture
  1. Salt Alternatives
    To reduce sodium, use:
  • Herb blends like rosemary, thyme, or garlic powder
  • Smoked paprika or chili powder for bold flavor without extra salt
  • A squeeze of fresh lemon juice or apple cider vinegar for brightness

Optional Add-Ons and Flavor Enhancements

The base recipe for skinny smashed sweet potatoes is simple and healthy, but there are plenty of ways to enhance the flavor based on your family’s preferences. Here are a few of my favorite variations:

  • Sprinkle cinnamon and a touch of maple syrup for a sweet twist
  • Add chopped fresh herbs like parsley, thyme, or rosemary
  • Top with a spoonful of Greek yogurt or cottage cheese for extra protein
  • Add crushed pecans or walnuts for a crunchy topping
  • Drizzle with balsamic glaze or tahini for a gourmet finish
  • Mix in roasted garlic or caramelized onions for rich, savory flavor
  • Sprinkle feta or goat cheese for a salty contrast (or use dairy-free alternatives)

These upgrades also help your post target more search-friendly terms such as “sweet and savory smashed sweet potatoes,” “low calorie sweet potato side dish,” or “healthy sweet potatoes with Greek yogurt.”

Cooking Tips for the Best Texture and Flavor

Here are a few mom-tested tips that help your smashed sweet potatoes turn out perfect every time:

  • Boil or roast the sweet potatoes until fork tender, then gently flatten with a spoon or fork
  • Roast in the oven at high heat (400–425°F) to get crispy edges and caramelized flavor
  • Use parchment paper for easy cleanup and to prevent sticking
  • Flip halfway through roasting for even browning
  • Serve immediately while warm and crispy

    1. Measure it out in your yellow container. Because of the amount of yogurt in it, I counted it as 1 yellow and 1 red. Thanks for stopping by!

      1. If it makes 6-8 servings and you only use 3/4 cup yogurt for the whole recipe – wouldn’t it be less than 1 full red per serving?

        1. Yes I am definitely overestimating when it comes to the red container. You can get 6-8 yellow sized containers of the recipe, depending on how big your sweet potatoes are. I didn´t want to just count the yellow though because of the protein in the yogurt, so I counted an entire red container. You could probably say it is only 1/2 a red, or even 1/4, depending on how much you eat, but I rather overestimate than under!

        1. Debbie, I use a miniscule amount. Just a sprinkle mostly for color. You could definitely leave it out!

  2. Hi,
    I love your recipes. Is there anyway to get them all at once instead of clicking on each individual one?
    Thank you for your blog.

    1. Hi kim! Thank you! I am not exactly sure what you mean, but if you would like to see an index of all my recipes at once you can click the recipe index at the top. At this time it is just the links to each individual recipe!

    1. Hi Amanda! It is hard to determine because everyone’s idea of a medium sized potato is different, but I would say 4 adult serving sizes as a side dish. If you are doing the 21 Day Fix, you could get easily get 6-8 containers full of sweet potatoes.

  4. You can also roast the sweet potato instead of boiling or steaming and it’ll add an extra layer of flavor without actually adding something to it. It makes them sweeter 🙂

    1. That would be delicious! I love roasted veggies but never thought of roasting a potato before mashing them! Thanks for sharing!!

  12. Hi Amanda, This recipe looks great. I LOVE sweet potatoes, I was just wondering how much brown sugar I should use in the recipe. Thanks.

    1. Hi! I just used a sprinkle across the top, it was probably around 1 tsp for the entire bowl.

  13. Hi! I love this recipe (found on pinterest) – how many calories would you say one serving would have?

    1. Hi Katie! I’m sorry but I’m not sure! I’m really not good at figuring out calorie counts and it would also depend on your brand of yogurt. I would add the calories of one sweet potato plus your brand of yogurt to determine the calorie count.

  15. There was way too much cinnamon for our taste, will cut it back next time but otherwise good!

    1. I tend to go heavy on the cinnamon because it is one of my favorite flavors, but I am glad you liked it otherwise and will try it again! Thank you so much for stopping by and letting me know!!

    1. Devon, I don’t include calorie counts in recipes because t I have no idea how to accurately count them! This recipe is for the 21 Day Fix, so a serving size is the size of one yellow container, or about 1/2 a cup.
