This Vegan Lentil Spaghetti is a healthy, hearty pasta dish made with protein-rich lentils and simple tomato sauce. It’s perfect for a quick, plant-based meal that’s both filling and tasty.
I like to add a little extra garlic or fresh herbs on top—I think it makes the dish even better! Plus, it’s friendly to both your wallet and the planet.
I recommend serving it with a side of green salad for a complete, balanced meal. It’s easy to prepare and suits busy weeknights when you want something nutritious and satisfying.
Ingredients & Substitutions
Red Lentils: These cook quickly and add a hearty, protein-rich base. I prefer cooking them until soft but intact—if overdone, they can get mushy. You can swap in green lentils if you prefer a firmer texture, but adjust cooking times.
Spaghetti: Use your favorite vegan or gluten-free pasta for the perfect bite. I recommend al dente to prevent it from becoming mushy. For a different twist, try zucchini noodles—just add them briefly at the end for a fresh feel.
Garlic & Onion: Classic flavor builders. I always toast them lightly in a bit of olive oil for added depth. If you’re sensitive to garlic, reduce the amount or replace with garlic powder. Onion powder can also work in a pinch for convenience.
Tomatoes or Tomato Paste: Provide richness and flavor. Fresh chopped tomatoes add brightness, while paste creates a thicker sauce. If avoiding tomatoes, sauté some red bell peppers with spices for a sweet alternative.
Herbs & Spices: Basil, oregano, salt, and pepper give the dish its signature taste. I love fresh basil if available; otherwise, dried works great. Feel free to swap parsley or thyme based on your preference—use what you have on hand.
How do I cook lentils without overcooking them?
Start with rinsed lentils and enough water or broth. Bring to a boil, then reduce heat to a gentle simmer. Cook uncovered for 15-20 minutes, stirring occasionally. Check for doneness—lentils should be tender but hold their shape. Drain if needed.
- Use a timer to avoid overcooking.
- Keep an eye on them after 15 minutes—test regularly.
- If they get mushy, drain immediately and use for a different dish.
