Brown lentils, if the question is value. They returned 77.7 grams of protein per dollar against 56.0 for red lentils in our July 2026 pricing, and that gap has almost nothing to do with the lentils. It’s the price sticker. A 16 ounce bag of brown cost $1.44 and the same size bag of red cost $1.94.
Per 100 grams, the two are nearly identical. You’re paying 35 percent more for a bag that gets processed differently.

| Red lentils | $1.94 | 23.91 g | 10.8 g | 56.0 g | 25.3 g |

Which lentils are the best for the money?
Brown, and it isn’t close. At $1.44 the bag holds about 112 grams of protein and 49 grams of fiber, which puts brown lentils fourth in our whole protein per dollar ranking of 49 foods. Only pinto beans, whole wheat flour, and dry black beans beat them.
Red lentils are the same food with the hulls removed and the seeds split, which costs money to do and shows up on the shelf. You’re not buying more nutrition. You’re buying a different texture, and sometimes that’s exactly what you want.
Two limits worth stating plainly. We priced brown lentils, red lentils, and green split peas. We did not price French green lentils, beluga lentils, or yellow split peas, so if you came here for those, we genuinely don’t know. And these are single store prices from one July, not a national average.
Brown lentils vs red lentils: what actually differs
In the pot, everything. On the label, almost nothing.
Red lentils fall apart. That’s not a flaw, it’s the whole reason they exist. They collapse into a thick, creamy base without you doing anything clever, which is why they carry a lentil curry so well. Nothing else in the aisle thickens a sauce that willingly.
Brown lentils stay recognizable. They give you something to chew, they hold up in a salad the next day, and they don’t turn a soup into a puree by accident. If you want lentils that still look like lentils on the plate, that’s the bag.
So the honest advice is not “buy brown, red is a ripoff.” It’s that red lentils carry a convenience premium of about 50 cents a bag, and you should know you’re paying it.
Which lentils are best for soup?
Depends what you want the soup to be. Red for creamy and thick. Brown for brothy with texture.
And then there are green split peas, which quietly beat both. At 22.2 grams of fiber per 100 grams they carry more fiber than anything else in this table by a distance, and at $1.42 a bag they returned 71.0 grams of fiber per dollar. That’s second only to whole wheat flour in our fiber per dollar ranking, ahead of every bean we priced.
A single $1.42 bag holds roughly 101 grams of fiber. The same size bag of brown lentils holds about 49 grams, so you’re getting more than double the fiber for two cents less. It also becomes split pea soup with no soaking step at all, which makes it the least demanding pulse in the aisle.
If your fiber intake is currently low, don’t celebrate by eating a whole pot. Ramping up fast is uncomfortable, and gradual works better.
Do lentils have more protein than meat?
Per dollar, yes, by a lot. Brown lentils returned 77.7 grams of protein per dollar against 24.5 for boneless skinless chicken breast. That’s about 3.2 times more protein for the same money, and we ran the full comparison in lentils versus chicken breast.
Per 100 grams the two foods sit much closer together, and animal proteins carry a better amino acid profile. Legumes and grains complement each other on that front, which is the argument for eating lentils alongside rice or bread rather than by themselves. The cheapest versions of that pairing are in complete protein pairs.
Which bag should you buy first?
Brown lentils if you want the best protein per dollar and a pulse that behaves predictably. Green split peas if you want fiber and one very good soup. Red lentils if you want a sauce that thickens itself and you’re fine paying for it.
If you’re stocking a cupboard from scratch, buy brown lentils and split peas, skip red for now, and add a bag of dry black beans. That’s roughly $5 of food that goes a long way, and it keeps for a long time if you store it properly, which we covered in how long dried beans last. The wider comparison across ten beans and pulses is in the nutritional value of beans, and where all this sits against canned convenience is in canned beans versus dried beans nutrition.
