Why We Love Fish in Tomato Sauce
Feeeeeeeesh!
Most of us have a strong reaction to fish. We either love all things seafood and can’t get enough. Or we sneer at the sheer thought of it.
Well, I’ve got a simple, healthy recipe today that will please fish lovers and might even turn a few haters over to our side.
This Fish in Tomato Sauce recipe is a quick and easy midweek meal consisting of pan-seared fish and zesty pomodoro sauce with herbs.
It’s a gluten-free, dairy-free, low-fat, paleo dinner option with rich Italian cuisine appeal!
What is the Best White Fish for Fish in Pomodoro?
The key to any good fish dish is to be very selective when purchasing your fish. Then prepare it right away.
Fresh fish is never stinky. Period.
Some types of fish indeed have a stronger flavor than others, but if they are fresh, they will not smell bad or have a twangy flavor.
Make sure to buy wild, fresh-caught fish when possible. If you have difficulty finding fresh fish where you live, ask the person behind the seafood counter to get you completely frozen fish fillets from the back.
Never (ever) buy the fish that has been thawed and sitting out in the case all day.
This Italian Fish in Red Sauce recipe calls for “white fish,” meaning whatever kind of light, flaky white fish you like best!
I used grouper fillets in the photos, however it tastes amazing with monkfish and even cod.
What is Pomodoro Sauce?
Pomodoro sauce is a quick-made tomato sauce that is heavy on basil.
This time of year, I like to use canned crushed tomatoes in my Pomodoro sauce, but you can make it with sweet vine-ripened tomatoes during the summer!
The pomodoro sauce offers a fresh, vibrant note and rustic texture to the fish that is unique from most fish recipes.
Low-Carb White Fish Pomodoroย tastes amazing on its own, or pair it with fresh zucchini noodles to round out the meal!

Italian Fish in Tomato Sauce
Ingredients
- 3-4 skinless white fish fillets (grouper, cod, monkfish, halibut)
- 1 tablespoon olive oil
- 3 cloves garlic, minced
- 1 shallot, peeled and finely chopped
- 28 ounces crushed tomatoes (1 can)
- 1/2 cup roughly chopped basil
- 1 teaspoon honey
- Salt and pepper
Instructions
- Place a large skillet over medium heat. Add the oil. Salt and pepper the fish fillets on both sides. Once the oil is hot, sear the fish fillets until cooked through. For thin fillets like grouper, cook 2 minutes per side. For thicker fillets like cod, cook 4 minutes per side. Remove from the skillet and set aside.
- Add the garlic and shallots to the skillet. Saute for 2-3 minutes to soften. Then add in the crushed tomatoes and honey. Stir and simmer for 5 minutes. Taste, and salt and pepper as needed.
- Stir in the fresh basil and add the fish fillets back to the skillet. Simmer another 1-2 minutes to reheat the fish. Serve warm as-is or with a side of raw zucchini noodles.

Hi Sommer,
Would it be OK to poach the fish in the pomodoro sauce? Thank you for all of your great recipes! I really enjoy your web site and blog!

Hi Kristen,
Absolutely! The only reason I don’t do that is because the fish is more visually pleasing when it’s cooked separately. It turns pinkish-red when cooked in the sauce. That’s probably not a big deal to most people, but I like to eat pretty food. ;)
