Vegan Meatballs in Tomato Sauce
  1. Start by making the flax egg. Mix the flax meal with 3 tablespoons water, give it a good stir, and set it aside for about 5 minutes while you get everything else moving.
  2. Preheat your oven to 350°F (180°C) and line a large baking sheet with parchment paper.
  3. Heat 1 tablespoon olive oil in a skillet over medium heat. Add the diced onion and cook for around 3 minutes, until it starts to soften.
  4. Add the minced garlic and chopped mushrooms. Cook for another 2–3 minutes, stirring occasionally, until the mushrooms soften and some of their moisture cooks away.
  5. Transfer the cooked onion and mushroom mixture to a food processor. Add the walnuts and drained kidney beans.
  6. Pulse until you have a coarse mixture. Don’t blend it into a smooth paste. A little texture helps the bean balls hold together and gives them a better bite.
  7. Transfer the mixture to a bowl. Add the breadcrumbs, prepared flax egg, tamari, tomato paste, lemon juice, oregano, basil, salt, and smoked paprika.
  8. Mix everything together until evenly combined.
  9. Shape the mixture into walnut-size balls, aiming for roughly 16–20, and arrange them on the prepared baking sheet.
  10. Bake for 25–30 minutes, carefully turning the bean balls halfway through, until they’re firm and golden on the outside.
  11. While the bean balls are baking, bring a pot of water to a boil and cook the spaghetti according to the package directions. Drain when ready.

Make the Tomato Sauce

  1. Heat 1 tablespoon olive oil in a medium saucepan over medium heat.
  2. Add the chopped onion and cook for about 5 minutes, until softened.
  3. Add the crushed garlic and cook for another 1 minute, just until fragrant.
  4. Stir in the chopped tomatoes, tomato paste, crumbled ½ vegetable stock cube, and fresh basil.
  5. Reduce the heat and simmer for about 5–10 minutes, until the sauce thickens slightly.
  6. Taste before adding salt, since the stock cube and tomato paste already bring plenty of seasoning. Add black pepper and extra salt only if needed.
  7. Once the bean balls are baked, gently add them to the tomato sauce.
  8. Fold them through carefully so they get coated without breaking apart.
  9. Divide the spaghetti between four plates or bowls.
  10. Spoon the tomato sauce and bean balls over the pasta.
  11. Finish with nutritional yeast and extra basil if you like, then serve warm.

Easy Ingredient Swaps

Kidney beans: Black beans or cannellini beans can work.

Walnuts: Pecans, sunflower seeds, or pumpkin seeds are good alternatives.

Breadcrumbs: Use certified gluten-free breadcrumbs if needed.

Tamari: Soy sauce works if gluten-free preparation isn’t necessary.

Spaghetti: Penne, linguine, rigatoni, or another pasta works just as well.

Fresh basil: Use parsley if that’s what you have.

Mushrooms: Cremini, button, or baby portobello mushrooms all work.

Some Twist and Tweak Ideas

Add red pepper flakes to the tomato sauce for a little heat.

Mix nutritional yeast directly into the bean-ball mixture for extra savory flavor.

Add finely chopped spinach to the tomato sauce.

Use Italian seasoning instead of oregano.

Stir roasted red peppers into the tomato sauce before serving.

Add a little fennel seed to the bean balls for a more sausage-like flavor.

Serve the bean balls in a sub roll with tomato sauce for a vegan meatball sandwich.

Skip the pasta and serve them over creamy polenta.

Some Helpful Tips

Drain the beans thoroughly. Extra liquid can make the bean balls too soft.

Cook some moisture out of the mushrooms. Mushrooms contain a lot of water, so don’t rush that skillet step.

Don’t over-process the mixture. You want coarse crumbs, not bean paste.

Let the flax egg thicken. It needs a few minutes to become sticky enough to help bind the mixture.

Make evenly sized balls. They’ll cook more consistently.

Flip gently. Vegan bean balls are more delicate than meat-based meatballs, especially before they fully set.

Let them bake completely before saucing. This gives them a firmer outside so they’re less likely to break apart.

Some Budget-Friendly Tips

Kidney beans are inexpensive, especially if you buy store-brand canned beans or cook dried beans yourself.

Button mushrooms are usually cheaper than specialty mushroom varieties.

Walnuts are one of the more expensive ingredients, so sunflower seeds can be a lower-cost substitute.

Use dried basil in the bean mixture if fresh basil is expensive, and save a little fresh basil for serving.

Store-brand canned tomatoes, pasta, and breadcrumbs all work perfectly well here.

You can also stretch the meal further by serving it with garlic bread or a simple salad.

Some Serving Ideas

Vegan Meatballs in Tomato Sauce

Serve these vegan bean balls with:

  • Spaghetti
  • Penne
  • Linguine
  • Creamy polenta
  • Mashed potatoes
  • Garlic bread
  • Green salad
  • Roasted vegetables
  • Zucchini noodles
  • Crusty bread

For the classic version, spaghetti is hard to beat.

For something different, spoon the bean balls and tomato sauce over polenta or tuck them into toasted rolls.

Great for Meal Prep

The bean balls can be prepared ahead of time and refrigerated before baking.

You can also bake them completely, let them cool, and store them separately from the tomato sauce.

Keeping the balls and sauce separate helps them maintain a firmer texture.

When you’re ready to eat, warm the sauce first, then gently add the bean balls.

Some Storage and Reheating Tips

Store leftover bean balls and tomato sauce in an airtight container in the refrigerator for up to 3 days.

For the best texture, keep leftover pasta in a separate container.

Reheat the bean balls and sauce gently in a covered saucepan over low to medium heat.

Add a splash of water if the tomato sauce has thickened too much.

Individual portions can also be reheated in the microwave.

The baked bean balls can be frozen separately for up to 2 months. Freeze them on a tray first, then transfer them to a freezer-safe container once firm.

Final Thoughts

These Vegan ‘Meatballs’ in Tomato Sauce are hearty enough to stand up to a proper bowl of spaghetti while still keeping everything completely plant-based.

Kidney beans give them structure, mushrooms add savory flavor, walnuts bring a little richness, and the herbs and smoked paprika keep them far from bland.

Add that simple basil tomato sauce and you’ve got a classic comfort-food dinner with a plant-based twist that doesn’t feel like it’s missing anything.
