Decision guide
Choose Spaghetti

- You want to boost your protein intake without meat
Either works if
- You are simply craving pasta and will balance the rest of your day's nutrition
- You are adding a robust, protein-rich sauce that makes the pasta's protein difference less critical
Avoid both if
- You are on a strict very-low-carb or keto diet
- You have severe sensitivities to both gluten and legumes

Cook lentil pasta slightly less than the package says to avoid a mushy texture.
- 3
Rinse lentil pasta after cooking to remove excess starch that can make it gummy.
- 4
Pair spaghetti with a protein-rich sauce (like meat bolognese or lentil ragù) to balance its lower protein content.
- 5
If transitioning to lentil pasta, try mixing it half-and-half with regular spaghetti at first to adjust to the flavor and texture.
