Eru is a rich, dark-green soup from Cameroon, made with finely ground okazi (wild spinach) leaves and waterleaf, cooked with palm oil, meat, fish, and traditional spices. It is a beloved staple in many Central and West African homes, known for its thick, hearty texture and savory, slightly earthy flavor. This recipe gives you a genuinely useful, step-by-step guide to making a delicious eru at home, with practical tips for sourcing ingredients and adjusting the heat.
Ingredients
- 2 cups (240 g) dried okazi leaves (or 4 cups / 120 g fresh okazi, finely shredded)
- 4 cups (300 g) waterleaf, chopped (or substitute 3 cups / 250 g fresh spinach + 1 cup / 100 g chopped celery for texture)
- 1/2 cup (120 ml) red palm oil (or substitute 1/2 cup / 120 ml vegetable oil + 1 tbsp tomato paste for color)
- 1 lb (450 g) beef stew meat, cut into 1-inch cubes
- 1/2 lb (225 g) smoked fish (like mackerel or cod), deboned and flaked
- 1/2 lb (225 g) cow skin (kanda) or beef tripe, cleaned and cut into pieces (optional, for authenticity)
- 1 large onion (150 g), finely chopped
- 2 cloves garlic, minced
- 1-2 Scotch bonnet peppers (or habanero), minced (adjust to taste)
- 2 tbsp ground crayfish (or 1 tbsp shrimp paste)
- 2 beef bouillon cubes
- 1 tsp salt (or to taste)
- 1/2 tsp black pepper
- 4 cups (960 ml) water or beef broth
Instructions
- Prepare the greens: If using dried okazi, soak in warm water for 15 minutes, then drain and squeeze dry. Finely shred or grind to a powder using a food processor or mortar and pestle. If using fresh okazi, wash thoroughly, remove stems, and shred into very fine strips. Chop the waterleaf (or substitute) into small pieces.
- Cook the meat: In a large pot, add the beef, cow skin (if using), onion, garlic, bouillon cubes, salt, and black pepper. Add 2 cups (480 ml) of water. Bring to a boil, then reduce heat to medium-low, cover, and simmer for 45 minutes, or until the meat is tender. If using cow skin, it may need an extra 15 minutes; check for tenderness.
- Add the palm oil: Once the meat is tender, stir in the red palm oil. Let it simmer for 5 minutes, allowing the oil to incorporate and color the broth.
- Add the greens: Stir in the shredded okazi and waterleaf. Mix well. The greens will reduce significantly. Add the remaining 2 cups (480 ml) of water or broth, stir, and bring to a gentle boil.
- Season: Add the ground crayfish and Scotch bonnet pepper. Stir to combine. Taste and adjust salt if needed.
- Simmer: Reduce heat to low, cover, and let the eru simmer for 20-25 minutes, stirring occasionally, until the greens are soft and the soup has thickened to a stew-like consistency.
- Add the fish: Gently fold in the flaked smoked fish. Cook for another 5 minutes, just until the fish is heated through. Do not stir too vigorously to avoid breaking up the fish.
- Rest and serve: Remove from heat and let the eru rest for 5 minutes before serving. It is traditionally eaten with fufu, pounded yam, or garri.
Tips
- Okazi substitution: If you can’t find okazi, use an equal amount of finely shredded kale or collard greens. The texture will be slightly different, but the soup will still be delicious.
- Palm oil flavor: Red palm oil gives eru its characteristic color and earthy flavor. If you substitute with vegetable oil, add a teaspoon of paprika or achiote powder to mimic the color.
- Heat control: Scotch bonnet peppers are very hot. Start with half a pepper and taste before adding more. You can also remove the seeds to reduce heat.
- Don’t overcook the fish: Smoked fish can become tough and salty if boiled for too long. Add it at the end and heat just until warmed through.
Serving Suggestions
Eru is traditionally served with a starchy side to soak up the rich sauce. Fufu (made from cassava or plantain flour), pounded yam, eba (garri), or boiled white rice are all excellent choices. For a lighter meal, serve it with steamed plantains or crusty bread.
Variations
- Vegetarian Eru: Omit the beef and fish. Use vegetable broth and add 1 cup (150 g) of diced eggplant or mushrooms for texture. Add the greens and season with extra crayfish or a teaspoon of smoked paprika for a savory depth.
- Chicken Eru: Replace the beef with 1 lb (450 g) of chicken thighs, cut into pieces. Cook until the chicken is done (165°F / 74°C safe minimum internal temperature).
- Spicy Seafood Eru: Add 1/2 cup (75 g) of cleaned shrimp or calamari along with the smoked fish during the last 5 minutes of cooking.
- Thicker Eru: If you prefer a very thick stew, mash some of the waterleaf before adding, or stir in 1 tablespoon of ground egusi (melon seeds) with the greens.
Storage and Reheating
Store leftover eru in an airtight container in the refrigerator for up to 3 days. The flavors will meld and often taste even better the next day. To reheat, place in a saucepan over medium-low heat, adding a splash of water or broth to loosen the sauce. Stir frequently until heated through. You can also freeze eru for up to 3 months; thaw overnight in the refrigerator before reheating.
Frequently Asked Questions
Can I use fresh okazi instead of dried? Yes, but you’ll need more. Fresh okazi is less concentrated, so use about 4 cups (120 g) of shredded leaves. You may also need to increase the simmering time slightly to soften them.
What is waterleaf and what can I substitute? Waterleaf is a succulent green with a slightly tangy flavor. If unavailable, a combination of spinach and celery works well, as the celery mimics the crunch and the spinach provides the leafy texture.
Is eru supposed to be soupy or thick? Traditional eru is thick and stew-like, almost like a hearty spinach dip. The amount of water can be adjusted; start with less and add more if it seems too dry.
Can I make eru without palm oil? Yes, you can use any neutral oil, but the flavor will be different. Palm oil adds a unique, slightly nutty taste that is hard to replicate. A good substitute is a mix of vegetable oil and a teaspoon of smoked paprika or annatto.
How do I reduce the bitterness of the greens? If your okazi or waterleaf is bitter, blanch them in boiling water for 2 minutes, then drain and squeeze out the excess water before adding to the pot. This also helps soften them faster.
Can I use fresh fish instead of smoked? Yes, you can use fresh mackerel or cod. Add it at the same time as the smoked fish, but ensure it is fully cooked through to 145°F (63°C) safe minimum internal temperature. Fresh fish will not have the same smoky flavor, so you may want to add a drop of liquid smoke.
