The 3-Step Soak: in practice
Understanding Lentils and Macros
Lentils are small, lens-shaped legumes that come in various colors. Brown and green varieties hold their shape well, while red lentils break down quickly into a puree.
They are naturally low-fat and high-fiber. For a low-carb diet, use them as a topper rather than a base, as they contain about 20 grams of net carbs per cup.
- Brown lentils: Best for vegetarian soups and stews.
- Red lentils: Perfect for thick curries or pureed dips.
- French Green lentils: Hold their shape best for salads.
Common Mistakes to Avoid
The biggest mistake is overcooking. Mushy lentils lose their texture and turn into a paste, which ruins the mouthfeel of your dish.
Another error is ignoring the sorting process. Always spread them on a baking sheet to check for small stones or debris before washing.
- Never add acidic ingredients like lemon juice until the end.
- Avoid high-heat boiling which causes skins to burst.
- Do not store raw lentils in damp containers or they will spoil.
Storage and Shelf Life
Dry lentils last up to 12 months in an airtight container in your pantry. Keep them away from direct sunlight to maintain peak flavor.
Cooked lentils stay fresh for up to 5 days in the refrigerator. You can also freeze them in portions for up to 3 months for quick meal prep.
- Use glass jars for long-term pantry storage.
- Freeze in 1-cup portions for easy recipe scaling.
- Label bags with the date of purchase.
Pros and honest limits
- Inexpensive and shelf-stable
- High plant-based protein
- Fast cooking compared to beans
- Higher carb count than meat
- Texture can turn mushy easily

Substitutes and Pairings
If you are out of lentils, split peas are the closest match for texture and cook time. They share similar protein profiles.
For a lower-carb profile, try cauliflower rice or chopped mushrooms to mimic the texture of lentils in ground meat recipes.
- Split peas: Best for split pea soup or thickening.
- Chickpeas: Good for salads but require longer cook times.
- Black beans: Use as a substitute in taco-style bowls.

How do I know when they are done?
Taste them at 15 minutes. They should be tender but not falling apart.
Are lentils keto-friendly?
They are generally not considered keto due to the carb content. Use them sparingly as a side dish.
