This Spanish Tilapia is super easy and budget-friendly. I serve it with Saffron Rice and usually some sort of green veggie.

The truth is, we don’t eat a lot of fish or seafood at our house. Brian isn’t particularly fond of it … and I didn’t eat much of it growing up – so my knowledge of how to cook or prepare it is severely lacking compared to other things. However, this Spanish Tilapia, is one of the few fish dishes I adapted from a version my mom makes!
The extent of my fish or seafood experience growing up amounted to frozen fish sticks or clams, salmon patties and tuna sandwiches. No joke. I remember us having shark steak once ….. and something with shrimp maybe a handful of times? As a kid, I actually had it in my mind that “I didn’t like that kind of stuff” because, well, I never really had it.

As an adult, I am more adventurous in my eating (have I ever told y’all the story of my friend Ty and I at the Chinese restaurant?! Bahahaha!! If not, I’ll have to enlighten you to my shenanigans! Be forewarned, you may never want to be seen dining with me in public!) – and I have tried several fish and/or seafood dishes that I have enjoyed. Almost all of those experiences have been at restaurants – because I have no clue what I’m doing with those dishes. I’m learning, though! 🙂

Would you like to save this?
Ingredients
- 1 pound tilapia fillets
- salt & pepper, to taste
- a swirl of olive oil
- 1 small onion, chopped
- 2 cloves garlic, minced
- 1 can Italian-style diced tomatoes, 14.5 oz.
- ¼ cup sliced black olives
- ¼ cup sliced green olives
- ½ lemon, sliced
- cooked rice or pasta, for serving (optional)
Instructions
- Preheat your over to 400°F.
- Season the tilapia with salt and pepper and place it in a lightly sprayed or buttered baking dish or sheet pan.
- In a large skillet, heat the olive oil over medium-high heat. Add the onion and garlic and cook until the onion softens, about 4-5 minutes. Add the tomatoes, black and green olives, and lemon slices. Bring just to a boil and reduce heat to medium-low to maintain a simmer. Allow the mixture to simmer for 10 minutes.
- Divide the tomato mixture evenly over the tilapia.
- Bake for 10-13 minutes or until the fish flakes easily with a fork.
- Serve the tilapia with some of the tomato-olive mixture over the top with rice or pasta on the side.
Notes
To cook in a skillet on the stovetop:
- Season the tilapia with salt and pepper and set aside.
- In a large skillet, heat the olive oil over medium-high heat. Add the onion and garlic and cook until the onion softens, about 4-5 minutes. Add the tomatoes, black and green olives, and lemon slices. Bring just to a boil and reduce heat to medium-low to maintain a simmer. Allow the mixture to simmer for 10 minutes.
- Add the fish to the skillet and cook for 7-9 minutes or until the fish flakes easily with a fork. Discard the lemon slices.
- Serve the tilapia with some of the tomato-olive mixture over the top with rice or pasta on the side.

Your fish dish looks delicious, Jamie. Tilapia is not a fish that we get here in New Zealand, but I often make a similar dish with tomatoes, olives and potatoes using a local fish called tarakihi.
Great dinner idea!
I would love if you would link up with me and share!

Oh Jamie! It looks delicious I love Tilapia! Its funny because growing up I never had frozen fish or seafood. I didn't know what was that at all because obviously I lived in a country as small as an island and surrounded by 2 oceans but when I got to the US, well finding fresh seafood when you don't live anywhere near an ocean is close to impossible. I miss the good old fresh days and would love to go in a tasting adventure with you. I bet we would have a blast! lol…have you ever eaten sea urchin? Ha! hugs girl, Lizy
Hi Jamie,
