What is caponata?
Caponata is a traditional Sicilian dish with fresh vegetables and a sweet and sour sauce. One of my favorite things about the food from this region is that they’re full of fresh ingredients and are so naturally healthy!
Caponata is somewhat similar to the French ratatouille. They both feature eggplant, tomatoes, and onions cooked in olive oil. Unlike ratatouille, though, caponata also includes olives, capers, and vinegar that gives the dish a delicious tang. It usually has a sweet component, like raisins or brown sugar, that adds another layer of flavor.
Ingredients
Onion – A red or white onion pairs best with the other flavors in the skillet.
Celery stalks – celery is consistently listed on the on the Dirty Dozen list put out by the Environmental Working Group, so you might want to opt for the organic celery.
Garlic cloves – use fresh garlic cloves for this recipe for the best flavor.
Eggplant – any type of eggplant will do for this recipe.
Tomatoes – use any variety of tomato, but you’ll probably need to drain off some of the juice before you add the remaining ingredients. Roma tomatoes are a great option since they’re so meaty.
Tomato passata – tomato puree could also be substituted.
Red wine vinegar – this helps add a savory depth of flavor to the vegetables.
Capers – these go great with the tomatoes and onion.
Olives – start with canned chopped olives or chop them yourself. Use black olives or ripe green olives, your choice!
Cod – 4-6 cod fillets
Almonds – use as many as you like!

How to make eggplant caponata
Once you’ve diced your veggies, you’ll cook the onion and celery, then add the eggplant and garlic. Some people prefer to cook the veggies separately before combining them, but I love the way the different flavors come together when you cook them together!
Add the tomatoes, tomato paste, passata, vinegar, and garnishes to your skillet, and let it simmer for about 15 minutes with the lid on. While you’re waiting for your caponata to finish, this is the perfect time to throw your cod fillets in the oven. Make sure you keep an eye on them because they cook quickly!
Next, remove the lid on the skillet and stir two tablespoons each of the fresh parsley and the toasted almonds into the caponata. Season the skillet to your own preference.
Finally, combine the skillet with the cod fillets and garnish with remaining parsley and almonds. Enjoy!

Baked Cod with Eggplant Caponata
Flaky, delicious cod fillets plated on top of a hearty eggplant caponata that is full of nutritious vegetables and savory flavors.
Ingredients
- 1/4 cup extra virgin olive oil, divided
- 1 medium white onion, diced
- 2 large celery stalks, diced
- 2-3 garlic cloves, minced
- 1 medium eggplant, peeled and cubed
- 2 medium tomatoes, diced
- 2 tablespoon tomato paste
- 1 cup tomato passata (or tomato puree)
- 3 tablespoons red wine vinegar
- 2 tablespoons capers
- ¼ cup green olives, pitted and sliced
- ¼ cup raisins
- 4 6-oz. cod fillets
- 3 tablespoons fresh parsley leaves, chopped, divided
- 3 tablespoons sliced almonds, toasted, divided
- Sea salt and black pepper, to taste
Instructions
1. Preheat oven to 400°F and line a large, rimmed baking sheet with parchment paper or a silicone baking mat. Set aside.
2. Heat 2 tablespoons olive oil in a large skillet over medium heat. Add the onion and celery, and season with salt and black pepper, to taste. Cook, stirring occasionally, until the onion is soft and translucent, approximately 4-5 minutes.
3. Add another tablespoon of olive oil to the skillet, along with the garlic and eggplant. Cook, stirring occasionally, until the eggplant begins to cook down, around 6-7 minutes.
4. Add the tomatoes, tomato paste, passata, vinegar, capers, green olives, and raisins. Stir to combine and cover skillet with a lid. Reduce heat to low and simmer gently for 15 minutes.
5. Meanwhile, lightly brush each cod fillet with the remaining olive oil and season with salt and black pepper on both sides. Place the fillets on the prepared baking sheet and place in the pre-heated oven to roast until the fish turns opaque and flakes easily with a fork, approximately 12-13 minutes. (Test after 10 minutes. Do not overcook.)
6. Remove lid and stir two tablespoons each of the fresh parsley and the toasted almonds into the caponata. Taste and adjust seasonings, as desired.
7. Transfer to individual serving plates and garnish with remaining parsley and almonds. Serve immediately with the cod fillets. Enjoy!
