Ingredients To Make Tilapia Recipe
- Extra virgin olive oil — Avocado oil will also work great!
- Produce — White onion and canned diced tomatoes or chopped cherry tomatoes.
- Seasonings — I like to keep things simple with salt and black pepper. But of course, you can add some paprika, red pepper flakes, cayenne pepper and other kind of spices you prefer.
- Optional — For a bit of extra flavor and color you can add some chopped parsley and sliced green olives if desired. Also, lemon slices are good here too or even a little bit fresh lemon juice or lemon zest.
Instructions to Make Tilapia Recipe
Heat olive oil:
- Place a skillet on the stovetop over medium-high heat, then add olive oil and let it heat up.
Sauté onion:
- Slice up your onion and add to the skillet. Stir and sauté for about 5 minutes until it softens and becomes translucent.
Add tilapia and tomatoes:
- Finally, add diced tomatoes (with juices), thawed tilapia fillets, salt and black pepper.
- Mix ingredients together really well, then cover and simmer for 7-10 minutes until the fish is fully cooked.
Garnish and serve:
- Do a quick taste test and add more salt/pepper if needed, then garnish with fresh chopped parsley and green olives.
- Plate, squeeze a little bit of lime juice, serve and enjoy!
Recipe Tips
- You can use frozen tilapia in this recipe! It’s a lot easier to find in many places, compared to fresh. Just be sure you let the fish thaw before cooking.
- Look for tilapia fillets that are similar in size when you do your shopping. This helps with quick, even cooking!
- Don’t overcook your tilapia fish. It really doesn’t take long at all for these thin fillets to cook all the way through and if overdone, they can become dry.
- You’ll know the tilapia is done when it easily flakes at the thickest part of the fillet and loses its translucent appearance. You can also use a meat thermometer to check for an internal temperature of 145°F.
How To Store Leftovers
To Store: Allow leftovers to cool and transfer them to an airtight container, refrigerate for up to 4 days.
To Freeze: Leftovers are also freezer friendly. Let them cool and place in a Ziploc bag or airtight, freezer-safe container and store frozen for up to 3 months.
To Reheat: Thaw leftovers in the refrigerator overnight (if reheating from frozen). Gently reheat sauce and fish in a pan on the stovetop until warmed through completely.
What To Serve With this Tilapia Recipe
Wondering what to serve with your tilapia recipe? Thankfully this quick main course meal pairs seamlessly with many sides.
- Soak up extra sauce with white rice, fluffy quinoa, garlic bread, dinner rolls or creamy mashed potatoes. You can also serve this saucy recipe over some fresh roasted spaghetti squash “noodles!”
- Make a quick veggie side! Garlic butter green beans, air fryer brussels sprouts or air fryer asparagus would all be tasty.
- You can’t go wrong with a simple arugula salad, spinach fruit salad, red cabbage salad or Mediterranean salad.
- A few more fun ideas: I also love this skillet with a side of leek kalamata rice, broccoli tots, cheesy cauliflower tots or baked sweet potato fries.
Recipe Variations
Substitute another kind of fish: This recipe would be great with either cod or halibut, both are white fish with a similar mild and sweet flavor profile.
Use flavored diced tomatoes: Instead of plain, canned diced tomatoes use fire roasted or Italian flavored! And if you’ve got some fresh tomatoes hanging around, feel free to dice them up and toss them in.
Experiment with spices: I typically use a simple salt and pepper blend for this tilapia recipe but you can certainly mix things up and use additional spices from your cabinet.
Recommended Tools
- Large Skillet: Use one with a lid and a large one to cook evenly your tilapia recipe!
- Sharp Knife: For prepping produce and cut all really well.
- Cutting Board: For chopping onion/cilantro. I like to use a wooden one
Frequently Asked Questions
Tilapia has a mild taste, which means it can be seasoned with pretty much anything! Here we’re using simple salt and pepper, though the tomatoes in this recipe add a ton of additional flavor.
Both salmon and tilapia are packed with protein and nutrients. They also both contain a decent amount of omega-3 fatty acids, however, salmon has a lot more.
You can use either fresh or frozen (I generally use frozen). Just be sure to thaw your fish before using it in this recipe.
