This 5-ingredient stovetop fish stew is one of those cozy, throw-it-in-the-pot dinners that makes weeknights feel special without a lot of fuss. You start with solid frozen tilapia fillets and let them simmer right in a simple, vibrant red tomato sauce made from basic pantry staples. It’s the kind of meal you can pull together when you forgot to thaw anything, but still want your family gathered around the table, dipping bread and asking for seconds.
Serve this fish stew ladled into warm bowls with crusty bread, garlic toast, or buttered rolls for soaking up the red sauce. A simple green salad or steamed green beans on the side keeps it light but satisfying. If your family likes a heartier meal, spoon the stew over hot cooked rice, egg noodles, or mashed potatoes. A squeeze of extra lemon at the table and a sprinkle of shredded Parmesan or crumbled feta can make it feel a little more special on a busy night.
5-Ingredient Stovetop Fish Stew with Frozen TilapiaServings: 4
Ingredients
1 tablespoon olive oil
2 cloves garlic, minced (or 1 teaspoon garlic powder)
1 (24-ounce) jar marinara or plain pasta sauce (about 3 cups)
1 cup low-sodium chicken or vegetable broth
1 1/2 pounds frozen tilapia fillets (solid, not thawed)
1/2 teaspoon salt, or to taste
1/4 teaspoon black pepper, or to taste
1 tablespoon fresh lemon juice (optional, but brightens the flavor)
Directions
Set a medium or large Dutch oven on the stovetop over medium heat. Add the olive oil and let it warm for about 1 minute.
Add the minced garlic to the pot and cook, stirring, just until fragrant, about 30 seconds. (If using garlic powder instead, wait and add it with the broth in the next step so it doesn’t burn.)
Pour in the jar of marinara or pasta sauce and the chicken or vegetable broth. If using garlic powder, stir it in now. Season the sauce with the salt and black pepper. Stir well to combine.
Bring the red sauce to a gentle simmer over medium heat, stirring occasionally, about 3 to 5 minutes. You want it bubbling lightly but not boiling hard.
Once the sauce is simmering, carefully lay the solid frozen tilapia fillets right into the Dutch oven in a single layer as much as possible. It’s fine if they overlap a bit; just nestle them down into the sauce so they are mostly covered.
Cover the Dutch oven with a lid, reduce the heat to medium-low, and let the fish cook undisturbed for 10 minutes. The sauce should be gently bubbling, not vigorously boiling. Adjust the heat as needed to keep a low simmer.
After 10 minutes, remove the lid and use a spoon or spatula to gently break the tilapia into large, rustic chunks, turning them in the sauce so they cook evenly. Be gentle so the fish doesn’t completely fall apart.
Continue to simmer the stew uncovered for another 5 to 10 minutes, stirring occasionally, until the tilapia is opaque and flakes easily with a fork and the sauce has thickened slightly. Total cook time for the fish from frozen is usually 15 to 20 minutes, depending on thickness.
Taste the sauce and adjust the seasoning with more salt and pepper if needed. Stir in the lemon juice, if using, for a bright finish.
Ladle the hot fish stew into bowls, making sure everyone gets plenty of both fish and sauce. Serve right away while cozy and steamy, with your favorite bread or sides for dipping.
Variations & Tips
For picky eaters, you can break the tilapia into smaller pieces and serve it more like a chunky pasta sauce over noodles or rice; kids often like it better that way. If your family doesn’t love strong tomato flavor, use half marinara and half broth for a milder red sauce. You can also add a drained can of white beans or chickpeas to the sauce when you add the broth to stretch the stew for more servings and extra protein. For a little heat, stir in a pinch of red pepper flakes with the garlic. If you prefer a slightly creamier stew, swirl in a splash of heavy cream or half-and-half at the very end, just before serving. Food safety tips: Keep the tilapia frozen until you’re ready to cook and use it by the date on the package. It is safe to cook tilapia directly from frozen as long as it reaches an internal temperature of 145°F (63°C) in the thickest part; if you’re unsure, use an instant-read thermometer. Make sure the stew returns to a good simmer after adding the frozen fillets, and adjust the cooking time if the fillets are especially thick. Refrigerate leftovers within 2 hours in a shallow container and use within 2 days; reheat gently on the stovetop until steaming hot all the way through, and avoid reheating more than once for best quality.
