How to Make Vegan Sweet and Sour Meatballs

Preheat the oven to 350°F (175°C). Begin by setting your oven so it’s ready for those delicious meatballs.
Mix the ground flax or chia seed with water in a small bowl to create a flax/chia egg. Let it sit for 5 minutes to thicken up.
Sauté the chopped onion and minced garlic in a large skillet with olive oil over medium heat until translucent, about 4-5 minutes.
Add the quartered shiitake mushrooms to the skillet and cook until softened, approximately another 5 minutes. The earthy aroma will fill your kitchen!
Combine the toasted walnuts, oats, cooked beans, thawed tofu, miso, nutritional yeast, tomato paste, dried thyme, nutmeg, baking powder, salt, and pepper in a food processor. Pulse until a dough-like mixture forms, approximately 30-45 seconds.
Incorporate the flax/chia egg into the mixture and pulse again to combine everything well.
Form the mixture into meatballs, about 1-2 inches in diameter, and place them on a lined baking sheet.
Bake the meatballs in the preheated oven for about 25-30 minutes or until golden brown, checking at the 25-minute mark.
Prepare the sweet and sour sauce while the meatballs are baking. In a saucepan, combine ketchup, rice vinegar, soy sauce, mirin, sugar, and cornstarch. Heat over medium heat, stirring until thickened, around 5 minutes.
Serve the meatballs with the sweet and sour sauce drizzled on top, making your dinner table look vibrant and inviting!

Optional: Garnish with chopped green onions for a fresh touch.

Vegan Sweet and Sour Meatballs Recipe FAQs

How do I choose the right mushrooms for this recipe?
Absolutely! When selecting shiitake mushrooms, look for firm caps that are dry to the touch without any dark spots or excessive wrinkles. Fresh shiitakes should have a strong, earthy aroma. If they feel slimy or have dark spots all over, it’s best to skip them. Alternatively, you can also use portobello or cremini mushrooms if you prefer.

How should I store leftovers of the Vegan Sweet and Sour Meatballs?
Very! After cooking, let the meatballs cool completely. Store any leftovers in an airtight container and refrigerate them for up to 4 days. When reheating, cover them with a damp paper towel in the microwave to prevent them from drying out, or reheat in a skillet with a little water.

Can I freeze the meatballs, and if so, how?
Absolutely! To freeze the Vegan Sweet and Sour Meatballs, first place the baked meatballs on a baking sheet in a single layer and freeze them for about 1 hour until firm. Then, transfer them to a freezer-safe resealable bag, removing as much air as possible to prevent freezer burn. They can be stored for up to 3 months. When you’re ready to enjoy them, simply reheat from frozen in a 350°F (175°C) oven for around 20 minutes or until heated through.

What should I do if my meatballs are falling apart?
If your meatballs are falling apart, don’t worry! This can happen if the mixture is too dry or doesn’t have enough binder. Make sure you’re using the correct amounts of flax or chia egg and pressed tofu. You can add a little more oats or a splash of water to the mixture to help it hold together. Also, ensure to pulse the ingredients just until combined to maintain some texture without making it too mushy.

Are these meatballs suitable for gluten-free diets?
Yes, they can be! If you need to keep your Vegan Sweet and Sour Meatballs gluten-free, simply substitute the soy sauce with gluten-free tamari and use certified gluten-free oats. Always check the labels on all ingredients to ensure they are gluten-free, especially the ketchup and mirin.

Can I share these meatballs with my pets?
It’s best to avoid sharing the Vegan Sweet and Sour Meatballs with your pets. While most of the ingredients are safe, foods like garlic and soy sauce can be harmful to dogs and cats in larger quantities. Always opt for pet-safe treats when sharing with your furry friends!
