Lentil Soup (Plant-Based Protein, 18g Protein)

2026-02-268 min read + cook time 40 min

[!TIP] Canned lentils work

  • No sorting, no soaking, cook time 15 min vs 45 min
  • Slightly more expensive, huge time savings
  • For GLP-1 low-energy days: Use canned

Why This Works

Lentils advantages:

  • Plant protein: 18g per bowl without animal products
  • Fiber: 12-15g per bowl (excellent for digestion, satiety)
  • Inexpensive: $2-3 for entire pot (4+ meals)
  • Comfort food: Soups feel substantial, warm, satisfying
  • Long shelf life: Dry lentils last 1+ years in pantry

GLP-1 specific:

  • One bowl = legitimate meal (18g protein)
  • Soups are easy to digest (cooked thoroughly)
  • Fiber = satiety = you feel satisfied with less
  • Plant protein = no heavy feeling of dense meat

Base Recipe (Dry Lentils)

Ingredients (makes 4 bowls):

  • 1 cup dry lentils (brown or green lentils)
  • 6 cups vegetable broth (or chicken broth if not vegetarian)
  • 1 onion, diced

  • 2 cloves garlic, minced
  • 2 tbsp olive oil
  • 1 tsp dried thyme OR fresh thyme sprigs

  3. Add lentils + seasonings: Add lentils, thyme, bay leaf.
  4. Add broth: Pour in 6 cups broth+ can of tomatoes (if using).
  5. Simmer: Bring to boil, reduce heat, simmer 35-40 min.

Flavor Variations

Classic Tomato Lentil

  • Add 1 can diced tomatoes
  • 1 tsp tomato paste for depth
  • Fresh basil at the end

Spicy Red Lentil Soup

  • Use red lentils (thickens naturally)
  • Add 1 can diced tomatoes + 1 tsp cumin + 1 tsp paprika
  • Optional: Cayenne pepper to taste

Italian Style

  • Add 1 can diced tomatoes
  • Fresh rosemary + thyme
  • Finish with grated parmesan (adds 3g protein + flavor)

Curry Lentil

  • Replace thyme with curry powder (1-2 tbsp)
  • Add 1 tsp turmeric + 1 tsp coriander
  • Coconut milk splash (1/4 cup) adds creaminess

Serving Ideas

As meal (18g protein per bowl):

  • Pure: Just soup (filling enough for GLP-1 portion)
  • With side: Small crusty bread (100 cal), or croutons
  • Protein boost: Add 1-2 oz shredded chicken or 1 egg boiled (adds 10g protein per egg = 28g total protein)

As side:

  • Half bowl = 9g protein (great alongside main protein)
  • Pair with smaller protein + veggies

Garnishes:

  • Fresh herbs: Parsley, thyme, basil (adds freshness)
  • Crusty bread: Dip in broth, adds substance
  • Yogurt dollop: Plain Greek yogurt (adds protein + creaminess)

Meal Prep & Storage

Making ahead:

  • Soups actually taste better next day (flavors meld)
  • Make a big batch (double above recipe).
  • Portion into 4 containers.

Freezing:

  • Lentil soup freezes well (3-6 months)
  • Leave slight headroom for expansion (don't fill to brim)
  • Reheat from freezer in microwave 3-4 min + stir halfway.

Reheating:

  • Fridge to microwave: 2-3 min
  • Freezer to microwave: 3-4 min + stir
  • From freezer to fridge overnight = faster reheating

Lentil Varieties

| Lentil Type | Cook Time | Texture | Best For | |-------------|-----------|---------|----------| | Brown lentils | 35-45 min | Holds shape | Soups, stews | | Green lentils | 35-40 min | Holds shape | Salads, soups | | Red lentils | 20-25 min | Softens/thickens | Thick soups, curries | | French green/Puy | 30-40 min | Texture | Salads, fancy dishes |

Recommendation:

  • Brown or green lentils for most soups (texture holds up)
  • Red lentils if you want thicker, creamier texture
  • French green are similar to green but more expensive

Buying & Storing

Storage:

  • Dry lentils: Cook for 1+ years in pantry, cool dry spot
  • Canned lentils: Keep 1+ years in pantry
  • Cooked lentils: 3-4 days fridge, 3-6 months frozen

Where to buy:

  • Grocery store: Bulk bins or packaged
  • Bulk stores (Costco): Large bags (good if you cook weekly)
  • Online: Sometimes organic/imported lentils

Quality:

  • Whole, unbroken lentils cook evenly (sort out debris/discolored)
  • Check for expiration date (old lentils take forever to cook)

[!WARNING] Check labels on canned lentils

  • Some are pre-seasoned (adds sodium, extra flavor you may not want)
  • "Simple" or "plain" = just lentils in water = best flexibility
  • Rinse canned lentils to remove canning brine sodium

[!NOTE] Lentils + rice = complete protein

  • Lentils = plant protein but not complete (missing some amino acids)
  • Rice has complementary amino acids
  • Lentils + small portion rice = complete protein profile
  • NOT necessary daily, but good occasionally for variety

[!BONUS] Lentils are inexpensive

  • 1 lb dry lentils = $2-3
  • Makes 4+ generous bowls
  • Compare: 6 oz chicken = $4-5 for one meal
  • Plant protein = budget friendly
