California Walnut Meatless Meatballs present a plant-forward twist on a classic Italian comfort food, providing a satisfying texture and rich flavor without using beef. Finely chopped walnuts serve as the base, adding richness, structure, and umami when combined with aromatics, grains, and herbs. Baked until just firm, these versatile meatballs work well as an appetizer, a main course, or part of a menu, paired with walnut pesto or Muhammara. Designed for both foodservice flexibility and home cooking, they demonstrate how California walnuts can support familiar dishes while meeting the growing demand for tasty meat alternatives.

Preheat oven to 400°F (200 °C) and line a baking sheet with a nonstick mat or parchment paper.
Heat oil in a small saute pan over medium heat. Add onion and garlic and sauté for 1 minute. Add tomato paste and cook, stirring constantly, for 1 minute more.
Set aside to cool.
In a food processor workbowl, pulse walnuts 5-10 times until semi-finely ground, with pieces no larger than a pea.
Add the cooked mixture to walnuts, then add rice, peppers, breadcrumbs, parmesan cheese, parsley, eggs, thyme, oregano, chilies, salt, and pepper.
Pulse until combined, retaining a ground texture and not pasty.
Transfer mixture to bowl, mix well with spatula, and check the seasoning and consistency. If the mixture is too wet, add more ground walnuts and breadcrumbs.
If it’s too dry, moisten with olive oil, roasted red pepper juice, or egg.
Form into 16 equal balls and place on the prepared baking sheet. Cook for 12 minutes or until firm to the touch.
Serve with California Walnut Pesto or Muhammara Sauce.
