Irresistible Sweet Potato “Meatballs” | Spanish-Style in Onion Sauce

These sweet potato “meatballs” in onion sauce are packed with flavors, made with simple everyday ingredients, and done in a little over 30 minutes. Serve them next to some roasted potatoes, a garden salad, and a bottle of Spanish wine for a fabulous meal.

Sweet Potato "Meatballs"

To make this recipe, I used 2 small sweet potatoes. You can also use 1 medium-sized one. Either way, you want to end up with 2 cups (220 grams) of shredded sweet potatoes. I also left the skins on, as it adds more nutrients and flavors. If you prefer, you can peel the sweet potatoes.

For the onion sauce, I used homemade vegetable broth. But you can also use chicken broth or even beef broth. I also added a little white wine to give the sauce a deeper depth of flavor. If wine is not your thing, you can sub for white grape juice or any broth of your choice with a squeeze of fresh lemon juice.

TIPS & TRICKS to Make this Recipe: The secret to these meatballs is to ensure the sweet potato mixture is well bound together. That way the meatballs don’t fall apart. Once you have the mixture ready, make sure to squeeze the mixture in your hands before shaping the meatballs. If you see it’s too dry, add in some whisked egg and mix until the desired texture.

    These were delicious. I hadn’t thought about squeezing the fluid out of the potatoes before – that made a big difference,
