    grilled tilapia with avocado sauce over it

    This fajita-spiced stovetop tilapia with a quick avocado sauce is the weeknight dinner of our dreams. If you've ever wondered How to Grill Tilapia on the Stovetop...keep reading!

    This recipe uses a flavorful shortcut of store-bought fajita spice mix for the seasoned tilapia, then simply sear the fish in a little neutral oil. Make the creamy sauce and dinner is ready!

    Before we get to the step by step directions, a few notes about the ingredients:

    Tilapia: tilapia fillets are a popular choice for simple fish dishes, but any mild white fish fillets will work for this recipe. Haddock, hake, cod, catfish, snapper, sea bream or branzino fillets are all flaky fish that would take work well in this recipe.

    Fajita seasoning: I have used Old el Paso, a local store blend, and even made my own spice rub using chili powder, cumin, garlic powder, onion powder, black pepper, brown sugar, cornstarch and a touch of oregano. If you have a packet of taco seasoning in your cabinet, that's a similar spice blend and it would work well as a substitute in this recipe.

    Cotija (or feta): a salty, crumbly, tangy cheese is the perfect addition to the sauce in this easy dinner. If cotija is hard to come by in your neighborhood, substitute feta cheese. 

    Full ingredient list and measurements included in the printable recipe card below.

    Step by step instructions:

    1. Make avocado sauce

    Begin your dish by making avocado crema. Combine avocado, Greek yogurt, Cotija (or feta), cilantro, mayo, lime zest and pickled jalapeños in a food processor and pulse until smooth. Refrigerate until ready to serve.

    2. Prep fish

    Dry fish fillets well using paper towels or an absorbent tea towel. Sprinkle top of fish generously with fajita seasoning.

    3. Pan-sear fish

    Heat 2 tablespoons of neutral oil in a skillet over medium-high heat. When hot, place seasoned tilapia (spice side down), in the skillet. Sprinkle bottom of fillets with remaining fajita seasoning.

    Let fish cook undisturbed for about 4 minutes, until it is cooked about 70 percent through. Use a fish spatula to turn the fillets and cook for remaining 2-3 minutes, until opaque and easily flaked with a fork.

    FAQ's and Serving Suggestions:

    Can I use frozen tilapia for this recipe?​

    Yes, you can use frozen tilapia for this recipe. Just make sure to thaw it completely before cooking. Pat the fish dry with paper towels to remove excess moisture before seasoning and grilling.

    What other seasonings work well with grilled tilapia?​

    Seasonings like lemon pepper, BBQ rub, Cajun seasoning and even Old Bay Seasoning work well with grilled tilapia. You can adjust the seasonings based on your preferences.

    How do I prevent the fish from sticking to the pan?​

    To prevent sticking, make sure your pan is properly preheated and oiled before adding fish fillets to the pan. You might also consider using a grill pan with raised ridges to create those nice grill marks and prevent direct contact between the fish and the pan.

    Can I use this recipe for other types of fish?​

    Yes, this recipe can be adapted for other types of flaky white fish with similar cooking times such as cod, haddock, hake, grouper or snapper.

    Can I use a non-stick skillet for grilling tilapia?​

    ​Yes, a non-stick skillet can be used for grilling tilapia on the stovetop.

    Why does my tilapia always stick to the pan?

    When the fish touches a hot metal pan, the heat forms a chemical bond with the muscle proteins in the fish, causing them to stick. To prevent sticking, make sure your pan is properly preheated and oiled before adding fish to the skillet.

    What's a good side dish to serve with grilled tilapia?​

    Grilled asparagus, Mexican Red Rice, Crispy Roasted Baby Potatoes, or Napa Cabbage Slaw make excellent side dishes to complement grilled tilapia. Check out my full post on What Sides Go With Tilapia for 28 of my favorite sides for fish.

    Can I use an outdoor grill instead of a stovetop grill pan?

    Absolutely! If you have an outdoor grill, you can follow the same recipe and grill the tilapia fillets on the grill grates. Just make sure to oil the grates before placing the fish to prevent sticking. For even easier grilling, cook fish in a grill basket for a slightly smoky flavor without the stress of turning fish over an open flame.

    How to store leftover grilled tilapia?

    To store grilled fish, transfer to an airtight container and keep in the refrigerator for up to 3 days.
