If you’ve made and enjoyed any of the vegetarian recipes I’ve created and shared in the past, you can thank meatballs, at least in part. Meatballs are largely responsible for converting me to a vegetarian diet. You see, I loved to help out in the kitchen as a kid. I also loved to eat meatballs. When it came to preparing meatballs, there was a little disconnect. The whole messy process of getting to know my food by digging my hands into a bowl full of meatball-to-be mixture just didn’t do it for me.
Interestingly enough, meatballs spent a long time on my vegetarian food wish list. Commercial vegetarian meatballs eventually became available, but like lots of meat substitutes, they were a bit disappointing.
Silver lining: homemade veggie meatballs are incredibly easy to make! There are a ton of options for replacing the meat part of meatballs, and my general rule is that if it works in a veggie burger, it’s at least worth a try in a meatball. The final dish that my meatballs end up in usually dictates what type of base I decide to go with. In this particular dish, sweet and sour flavors both come on pretty strong, as the name indicates.
These tempeh meatballs would work with most flavors and sauces, but with party season approaching, a pineapple sweet and sour seemed the way to go. (Sorry if you were holding out for grape-jelly meatballs!) In this recipe, just throwing some pineapple chunks into the sauce infuses it with loads of flavor. I also added a little Sriracha sauce, because if we’re doing sweet and sour, why not go all out and add some spicy to the mix?
Even better, these meatballs are incredibly quick and easy. The sauce is of the toss-everything-in-a-pot type, and it simmers for just a short time while the meatballs bake. It can also be made ahead of time, along with the tempeh meatball mixture. If you opt to go this route, just refrigerate everything until you’re ready to bake. When the time comes, roll your meatballs, bake them, and warm the sauce up on the stove just before the baking time is up.

Ingredients
For the tempeh meatballs:
- 2 tablespoons grapeseed oil or other neutral-flavored vegetable oil, divided
- 1 small onion peeled and quartered
- 3 garlic cloves
- 1 8-ounce package tempeh, broken into 1-inch chunks
- 1/2 cup panko breadcrumbs
- 2 tablespoons unflavored soy or almond milk
- 1 tablespoon soy sauce
- 1/4 teaspoon black pepper
For the sauce:
- 1 cup diced fresh or drained canned pineapple
- 1/2 cup vegetable broth
- 1/4 cup apple cider vinegar
- 1/4 cup brown sugar
- 2 tablespoons tomato paste
- 1 tablespoon soy sauce
- 1 teaspoon Sriracha sauce or to taste
- 2 tablespoons cold water
- 1 tablespoon cornstarch
Instructions
Make the meatballs:
- Preheat oven to 400°F. Coat a baking sheet or large cast-iron skillet with 1 tablespoon of grapeseed oil.
- Place the onion and garlic into the bowl of a food processor fitted with an S-blade. Pulse a few times until coarsely chopped. Add the tempeh and pulse a few more times until finely chopped. Add the remaining 1 tablespoon of oil, panko, milk, soy sauce and pepper. Pulse until mixed, scraping down the sides of the bowl as needed.
- Roll the mixture into 20 balls about 1 1/2 inches in diameter. Place the meatballs on the baking sheet or skillet and bake, turning twice while they bake, until golden brown, about 20 minutes.
Make the sauce:
- Place a medium saucepan over medium heat. Add the pineapple, broth, cider vinegar, brown sugar, tomato paste, soy sauce and Sriracha and stir to combine. Bring to a simmer, then lower heat to maintain the simmer and cook, stirring occasionally, for 10 minutes.
- Combine the water and cornstarch to a small bowl and whisk until smooth. Add the cornstarch mixture to the sauce and stir just until combined. Add the meatballs to the sauce and cook, stirring frequently, until sauce becomes thick and coats the meatballs, 1-2 minutes. Transfer the meatballs to a serving platter and spear with decorative toothpicks for serving.

October 29, 2014 at 8:44 pmThanks Karishma! Tempeh worked out great as a meatball base – easy and delicious. 🙂

October 30, 2014 at 12:34 pmI was JUST craving sweet & sour take out yesterday…but wasn’t sure how go about it in a meat-free way; this is perfect and looks insanely delicious! Thanks for the recipe, I’ve got to try these! 🙂
Alissa
October 31, 2014 at 10:36 pmI know the feeling! I think these will definitely satisfy your sweet and sour craving – hope you enjoy them! 🙂

October 30, 2014 at 3:53 pmHas anyone served these at room temperature? I was wondering if they would work for a work potluck where I won’t be able to heat beforehand. Thanks for any input!
Alissa
October 31, 2014 at 10:38 pmI didn’t try them at room temperature, but I did eat reheated leftovers after making these, and they were still good. Like more things, they’re probably best hot but I think they’d still be tasty at room temperature. 🙂

October 31, 2014 at 11:52 amI would happily make a whole meal of these! I really don’t cook with tempeh enough, but love the sound of it mixed into “meat”balls. It definitely has the right texture for it!
Alissa
October 31, 2014 at 10:47 pmHaha! I did make a meal of them and it was awesome! The tempeh worked perfect as a meatball base – it crumbles up really nicely.

November 11, 2014 at 8:29 amDo you steaM the temps first or use right from package?
Alissa
November 11, 2014 at 5:35 pmYou can use it right from the package! Some recipes call for steaming tempeh to cut the bitterness, but there’s a lot of other flavors going on here, so it’s not really necessary.

November 18, 2014 at 1:50 pmI really enjoyed making and eating these! I didn’t have breadcrumbs so I used chickpea flour instead. It came out nice and moist. I really like the sauce here too.. Great job!
Alissa
November 26, 2014 at 9:14 pmYay!!! Good to know that chickpea flour works as a substitute. Thanks so much for sharing – I’m very happy to hear you enjoyed them! 🙂

January 22, 2015 at 6:44 amThank you so much for this wonderful recipe!
We tried tempeh years ago and totally hated it – I thought of it as the most disgusting thing I ever ate. Thanks to your recipe, I became eager to give it another try and it turned out to be very delicious! Maybe I have to revise my opinion on tempeh 😉
Alissa
January 22, 2015 at 11:54 amAwesome! So glad you liked them! My husband is kind of finicky when it comes to tempeh – I think the key is to use it in recipes where it’s covered in really flavorful sauce, which is why I think it worked so well here. Thanks so much for sharing. 🙂

December 21, 2016 at 8:28 pmCan you make this the night before then freeze?
Alissa
December 22, 2016 at 9:43 amYou can make them the night before, and no need to freeze – everything should be fine in the fridge. I’d store the meatballs and the sauce separate, and then heat them up and combine on the day of serving.

January 10, 2017 at 9:15 pmIt would be nice if you included how firm they should be out of the oven. I think I just ruin everything because they were not that firm at all. Still moosh. I followed this recipe to the letter.
Alissa
January 11, 2017 at 10:13 amThey should be pretty firm when they come out of the oven – about the firmness of regular meatballs. Make sure you’re not over-blending the ingredients in the food processor – that will make them too soft, and it’s usually where I go wrong myself! Also, if you roll them too big, they’ll be soft in the middle. Otherwise, I’d suggest just giving them a few more minutes of bake time.

January 15, 2017 at 6:57 pmHi – the only tempeh I found where I was shopping today was maple bacon flavored, which I thought would be a terrible taste combo! I bought a sesame ginger marinated baked tofu package instead – do you think that would be firm enough for the meatballs, or would you recommend I go search for regular tempeh I need it?? I’ve never had tempeh and only occasionally tofu, so I’m not sure of all the differences. Thanks!
Alissa
January 16, 2017 at 9:28 amHi Stephanie! I’d hold off until you can get your hands on some regular tempeh. Tempeh has quite a different texture from tofu – it’s grainy and much firmer. I’d be afraid they wouldn’t hold together with tofu.
