Traditional Refried Beans vs. Lentil Soup: Which Is the Better Protein-Packed Side?

Quick Answer

Both traditional refried beans and lentil soup are solid protein-packed sides, but they serve different needs. Refried beans deliver more fiber per serving and a thicker, taco-friendly texture, while lentil soup offers more protein with a lighter, brothy consistency. Choose beans when you want a hearty side for Mexican dishes; choose lentil soup when you want a warming bowl that doubles as a main.

When you're staring at your pantry, deciding between a can of traditional refried beans and a can of lentil soup can feel surprisingly tough. Both are vegetarian, vegan, and gluten-free, and both pack a decent protein punch. But they're not interchangeable on your plate, and the better choice depends on what you're cooking and what you need nutritionally.

We compared two pantry staples from Amy's—Traditional Refried Beans, Light in Sodium and Lentil Soup, Light in Sodium—side by side. Here's how they stack up on protein, fiber, sodium, and real-world kitchen use.

Protein and Fiber: The Nutritional Core

Protein is the headline for both, but they reach it differently. Lentil Soup, Light in Sodium provides 6g of protein per serving, plus 4g of dietary fiber. That's a solid amount for a side, and it comes from organic green lentils, carrots, celery, onion, potatoes, and spices. The fiber count is respectable but not huge for a legume-based product.

Traditional Refried Beans, Light in Sodium, on the other hand, gives you 6g of dietary fiber per serving—more than the lentil soup—and also counts as a good source of iron and potassium. The protein content isn't listed in the catalog facts, but the fiber advantage makes beans the better choice for digestive health and staying full longer.

If you're focused strictly on protein numbers, the lentil soup has a clear stated advantage. But if you're looking at the full nutritional picture—fiber plus micronutrients—the refried beans pull ahead on fiber and potassium. Neither is a bad pick; it's about what your meal needs.

• Check the label: serving sizes differ between canned soups and beans, so compare per serving, not per can.

Sodium and Flavor: Light But Not Tasteless

Both products are Light in Sodium versions, with 50% less sodium than Amy's regular counterparts. That makes them friendlier for anyone watching salt intake. But lighter sodium doesn't mean bland. The Traditional Refried Beans are seasoned with organic onion, garlic, and spices, offering a savory, Southwestern flavor that works in burritos, tacos, or as a base for nachos.

Lentil Soup, Light in Sodium brings a different taste—earthy lentils with the sweetness of carrots and celery. It's less of a side and more of a mini-meal. The lower sodium helps the vegetables' natural flavors come through, but if you're used to high-salt canned soups, you may want to add a pinch of salt or a splash of hot sauce.

Flavor-wise, both are versatile, but they marry to different cuisines. Beans lean Mexican and Tex-Mex; lentil soup leans Mediterranean or simply homey. Think about what's already on your plate before you open a can.

Texture and Versatility: From Side to Meal

Texture dictates how you'll use each. Refried beans are thick and spreadable, making them ideal as a base or filler. They hold up in tacos, tostadas, and quesadillas, or as a simple side scooped up with tortilla chips. They're also easy to warm on the stovetop or microwave, and their density means they satisfy like a creamy side.

Lentil soup is brothy and chunky. It's more of a bowl food—perfect for pouring into a mug on a cold morning or serving alongside a grilled cheese. Because it's lighter, it works as a first course or a light lunch. It's less likely to be a 'side' in the traditional sense, and more often becomes the main event.

The trade-off is clear: beans give you more structural versatility in composed dishes; soup gives you a complete, hydrating meal with minimal effort. Both are pantry-friendly and ready in minutes, but they'll occupy different spots on your plate.

The Trade-Off at a Glance

• Fiber content: Refried beans offer 6g of fiber per serving, while lentil soup has 4g per serving. Choose beans if you're aiming to boost daily fiber intake.
• Protein content: Lentil soup provides a stated 6g of protein per serving; protein amount isn't listed on the beans. Pick lentil soup if you want a guaranteed protein number.
• Practical use: Beans are thick and spreadable for tacos and burritos; soup is brothy and bowl-ready for a quick meal. Decide based on what you're cooking tonight—not just nutrition.

What the Labels Say

• Traditional Refried Beans, Light in Sodium: 6g dietary fiber per serving, good source of iron and potassium, 50% less sodium than Amy's regular traditional refried beans, seasoned with organic onion, garlic, and spices. You get more fiber per serving, which helps with satiety and digestion. The lower sodium is a bonus for heart health, but check the serving size—it's easy to eat more than a single serving when beans are this tasty.
• Lentil Soup, Light in Sodium: 6g protein and 4g dietary fiber per serving, good source of iron, made with organic green lentils, carrots, celery, onion, potatoes, and spices, 50% less sodium than Amy's regular lentil soup. Protein is the standout here—6g per serving helps you hit daily targets, especially if you're plant-based. The broth adds hydration, but you might want a side of bread or a salad to make it a full meal.

Which One Fits Your Plate?

Best for

• People building high-fiber, plant-based meals who want a versatile side for Mexican-inspired dishes.
• Anyone who prefers a thicker, more filling side that can double as a spread or base.

Not ideal for

• Those looking for a brothy, soup-like option to serve as a main or light starter.
• Cooks who need a side with a listed protein content per serving.

Both the Traditional Refried Beans, Light in Sodium and the Lentil Soup, Light in Sodium are worthy pantry staples. If you need more fiber and a taco-friendly texture, reach for the beans. If you want a stated protein boost and a warming bowl that works as a meal, the lentil soup is your pick. Either way, you're getting a clean, plant-based side that fits a healthy kitchen.
