Instructions

Step 1
Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
Step 2
In a small bowl, mix ground flaxseed with water. Let sit for 5 minutes to form a flax egg.
Step 3
Heat olive oil in a skillet over medium heat. Sauté onion and garlic until soft, about 3 minutes.
Step 4
In a food processor, combine cooked lentils, sautéed onion and garlic, oats, breadcrumbs, tomato paste, nutritional yeast, flax egg, smoked paprika, oregano, cumin, salt, and pepper. Pulse until the mixture holds together but still has some texture.
Step 5
Form mixture into 16 golf ball-sized balls. Place on the prepared baking sheet.
Step 6
Bake for 20–22 minutes, flipping halfway, until golden and firm.
Step 7
While meatballs bake, heat olive oil in a saucepan over medium heat. Add onion and garlic, sauté 2–3 minutes. Stir in crushed tomatoes, tomato paste, basil, oregano, red pepper flakes, salt, and pepper. Simmer for 15–20 minutes, stirring occasionally.
Step 8
For the zucchini noodles, heat olive oil in a large skillet over medium-high heat. Add spiralized zucchini and a pinch of salt. Sauté for 2–3 minutes until just tender. Drain any excess liquid.
Step 9
Add baked lentil meatballs to the marinara sauce and simmer for 5 minutes to warm through.
Step 10
To serve, divide zucchini noodles among plates, top with lentil meatballs and spoon over marinara sauce.

Zusatztipps für die Zubereitung

To achieve the best consistency, ensure your lentils are well-drained before processing. Use a food processor to pulse the meatball mixture just enough so it holds together; over-processing may lead to a mushy texture. Make sure the flax egg has thickened for the full 5 minutes to ensure proper binding.

Varianten und Anpassungen

If you prefer a more traditional bite, you can easily swap the zucchini noodles for spaghetti or your favorite gluten-free pasta. To amplify the depth of the meatballs, consider adding a drop of liquid smoke to the mixture before baking.

Serviervorschläge

Enhance the final dish by garnishing with a sprinkle of vegan parmesan or fresh basil leaves. This meal is best served immediately after the zucchini noodles are sautéed to enjoy their tender-crisp texture before they release too much moisture.
