Most red lentil pastas list the same thing: about 6 grams of fiber and 14 grams of protein per 2 ounce serving, according to USDA FoodData Central branded records. That’s double the fiber and nearly double the protein of classic semolina spaghetti.
The twist is how closely those numbers match plain dry lentils. Below, we break down lentil pasta fiber by brand and color, flag why yellow lentil boxes deserve a second look, and show how to build a bowl that really delivers.
Lentil pasta fiber by brand
Here’s what several lentil pastas list in their USDA branded foods records, per 2 ounce (56 gram) dry serving:
| Pasta | Ingredient | Calories | Fiber | Protein | Carbs |
|---|---|---|---|---|---|
| Barilla Red Lentil Penne | Red lentil flour | 190 | 6 g | 14 g | 34 g |
| Tolerant Organic Red Lentil Penne | Organic red lentil flour | 200 | 6 g | 14 g | 33 g |
| Bentilia Red Lentil Rotini | Red lentil flour | 200 | 6 g | 14 g | 35 g |
| Tolerant Organic Green Lentil Penne | Organic green lentil flour | 210 | 6 g | 14 g | 35 g |
| Pasta Lensi Yellow Lentil Spaghetti | Yellow lentil flour | 200 | 3 g | 13 g | 35 g |
| Barilla Classic Spaghetti (for comparison) | Semolina | 200 | 3 g | 8 g | 41 g |
Four of the five lentil pastas land at exactly 6 grams. Every one of them uses a single ingredient, lentil flour, with nothing added.
The outlier is the yellow lentil spaghetti, at 3 grams. Its record dates from 2018, so the current box may differ, but it’s a reminder that “lentil” on the front doesn’t guarantee a fiber number.
Red lentil pasta fiber vs plain lentils
Red lentil pasta is essentially dry lentils, milled and shaped. The numbers show it:
| Per 56 grams, dry | Calories | Fiber | Protein | Carbs |
|---|---|---|---|---|
| Raw lentils (USDA FoodData Central) | 197 | 6.0 g | 13.8 g | 35.5 g |
| Barilla Red Lentil Penne | 190 | 6 g | 14 g | 34 g |
| Tolerant Organic Red Lentil Penne | 200 | 6 g | 14 g | 33 g |
Raw lentil values are scaled from USDA’s per 100 gram record. The pasta and the raw legume line up almost gram for gram, which tells you the milling and shaping don’t strip out the fiber.
Cooked lentils are a slightly different story. USDA’s cooked lentil record shows more fiber per calorie than its raw record, about 6.8 grams per 100 calories versus 3.0, and the database doesn’t explain the gap, so treat any pasta versus cooked lentil comparison as rough.
Lentil pasta as a high protein pasta
For anyone looking for a high protein pasta without protein isolates, lentil pasta is one of the simplest options. At 14 grams per serving, it beats classic spaghetti’s 8 grams by a wide margin.
The protein comes from the lentils themselves, not from added pea or wheat protein. Most of these boxes also list 0 milligrams of sodium and 3 to 4 milligrams of iron, about 17 to 22% of the Daily Value.
Tolerant’s red lentil record lists 520 milligrams of potassium per serving too, about 11% of the Daily Value, and its green lentil penne lists 480 milligrams.
Harvard’s Nutrition Source describes pulses like lentils as a source of protein, folate, iron and phosphorus with very little saturated fat. Lentil pasta carries that profile into a familiar dinner.
Reading a plant based pasta label
The FDA’s Daily Value for fiber is 28 grams, and a food with 20% of the Daily Value or more per serving counts as high in fiber. That line sits at about 5.6 grams.
Red and green lentil pastas at 6 grams clear it. Yellow lentil pasta at 3 grams doesn’t, and neither does classic wheat spaghetti.
Not every plant based pasta is a lentil pasta, either. Some boxes blend lentil flour with rice, corn or wheat, and those blends usually list less fiber than a single ingredient box.

Lentil pasta vs other high fiber pastas
Lentil pasta sits in the middle of the high fiber pasta range. Per 2 ounce dry serving, using USDA branded records:
- Barilla Chickpea Spaghetti: 8 g fiber, 12 g protein
- Red or green lentil pasta: about 6 g fiber, 14 g protein
- Barilla Whole Grain Spaghetti: 6 g fiber, 8 g protein
- Barilla Classic Spaghetti: 3 g fiber, 8 g protein
Lentil pasta ties whole grain wheat on fiber but wins clearly on protein. Chickpea pasta edges ahead on fiber, while lentil pasta has a little more protein and less fat.
Mayo Clinic’s fiber chart lists a cup of cooked whole wheat spaghetti at about 6 grams, which matches the dry serving numbers here. Any of these is a real upgrade from white pasta.
A red lentil pasta dinner, counted
Picture a bowl of Barilla Red Lentil Penne, one 2 ounce serving, tossed with marinara, a half cup of cooked spinach and a sprinkle of parmesan.
The pasta brings 6 grams of fiber and 14 grams of protein. The Dietary Guidelines for Americans list a cup of cooked spinach at 4.3 grams, so a half cup adds about 2.2, for a bowl near 8 grams.
Stir in a half cup of cooked lentils, which the Dietary Guidelines put at 7.8 grams, and the same bowl climbs to roughly 16 grams. That’s more than half of the Daily Value in one dinner, built entirely on lentils and greens.

Lentil pasta in a cold pasta salad
Lentil pasta isn’t only for hot dinners. Chilled and dressed, it makes a lunch that holds its fiber all week.
Picture a meal prep container with one 2 ounce serving of cooked green lentil penne, a cup of chopped raw red bell pepper, a handful of cherry tomatoes and a lemon and olive oil dressing.
The pasta brings about 6 grams of fiber. The Dietary Guidelines list a cup of raw red bell pepper at 3.1 grams, so the container lands around 9 grams before the tomatoes, with about 14 grams of protein from the pasta alone.
Make four of them on Sunday and you’ve covered about a third of the 28 gram Daily Value at lunch, Monday through Thursday. Toss the pasta with a little dressing while it’s still warm so it doesn’t stick together in the fridge.
Red, green or yellow: a quick color guide
Lentil pastas come in three main colors, and each behaves a little differently in the kitchen:
- Red lentil: mild and slightly sweet, the most common, 6 grams of fiber in the records above
- Green lentil: deeper and earthier, also 6 grams in Tolerant’s record
- Yellow lentil: mild and buttery looking, but 3 grams in the one record we found
If you only buy one, red lentil pasta gives you the most consistent fiber numbers across brands.
Cooking lentil pasta well
Lentil pasta cooks faster than wheat pasta and can turn soft if you leave it too long. It also tends to foam in the pot.
- Bring a large pot of water to a rolling boil before adding the pasta
- Stir in the first minute so the pieces don’t stick
- Taste a minute or two before the time on the box
- Drain promptly and sauce right away
Red lentil pasta has a mild, slightly earthy flavor that works well with tomato sauces, pesto and roasted vegetables. Green lentil pasta tastes a little deeper, which suits mushroom or garlic and greens sauces.
Lentil pasta and your gut
Lentils contain fermentable carbohydrates that gut bacteria break down, and Harvard’s Nutrition Source notes that legumes can cause gas and bloating in some people.
Doubling the fiber of your usual pasta in one go can be noticeable. Start with a smaller portion, pair it with plenty of water, and let your gut adjust over a couple of weeks.
If your digestion needs a gentler path, our gut health guides walk you through it step by step.
Which lentil pasta to buy
A quick rule for the pasta aisle:
- If fiber is the goal: pick a single ingredient red or green lentil pasta with 6 grams or more
- If you see yellow lentil: check the label, since some list only 3 grams
- If you want the most fiber of any legume pasta here: chickpea pasta at 8 grams edges ahead
- If protein matters most: lentil pasta’s 14 grams is among the highest without added isolates
Whichever you pick, compare boxes at the same 2 ounce serving. A quick glance at the fiber line takes seconds and saves you from the 3 gram surprise.
One swap to make this week
Next time you cook spaghetti or penne, buy one box of red lentil pasta and use it for a single pasta night. Same sauce, same toppings, and the bowl doubles its fiber from 3 to 6 grams per serving.
If the family likes it, add a half cup of cooked lentils to the sauce the following week. That one change pushes the bowl past 13 grams.
Lentil pasta questions
How much fiber is in lentil pasta?
Most red and green lentil pastas list about 6 grams of fiber per 2 ounce dry serving. Some yellow lentil pastas list as little as 3 grams.
Is red lentil pasta high in fiber?
Yes. Single ingredient red lentil pastas from Barilla, Tolerant and Bentilia each list 6 grams per serving, above the FDA’s 5.6 gram line for high fiber.
Is lentil pasta high in protein?
Yes. Most lentil pastas list about 14 grams of protein per serving, compared with 8 grams in classic spaghetti.
Does lentil pasta have as much fiber as lentils?
Close to it. A 2 ounce serving of red lentil pasta matches 2 ounces of raw lentils almost exactly, at about 6 grams of fiber.
Is lentil pasta gluten free?
Single ingredient lentil pastas contain no wheat. Look for a gluten free claim on the box if you need to avoid gluten strictly.
Which has more fiber, lentil or chickpea pasta?
Chickpea pasta can edge ahead. Barilla Chickpea Spaghetti lists 8 grams per serving, while most lentil pastas list 6.
Is lentil pasta good for weight loss?
It can help. Its fiber and protein make it more filling than white pasta at about the same calories, roughly 190 to 210 per serving.
