Parmesan Crusted Tilapia

Ingredients & Substitutions

Here I explain the best ingredients for my parmesan crusted tilapia recipe, what each one does, and substitution options. For measurements, see the recipe card.

Parmesan Crusted Tilapia:

• Tilapia Fillets – I’ve made this with both fresh and frozen tilapia — either one works! If yours is frozen, just rinse off any ice and pat it dry first. I usually use whole fillets, but loins are great too. You can even try other fish like flounder or haddock… or make my parmesan crusted salmon instead!
• Spices – Garlic salt, black pepper, and paprika are my go-to’s for flavor here. If you don’t have garlic salt, just mix garlic powder and sea salt instead. Lemon pepper works great too if you want a little zing!
• Herbs – I use dried regano and basil for that classic herby crust. Fresh herbs work too, but you’ll need to use about three times as much.
• Grated Parmesan Cheese – This is what gives the fish that golden, crispy crust. Don’t use shredded or shaved parmesan — it’ll melt instead of crisping up. I stick with the grated kind from a plastic can… it works best.
• Mayonnaise – I use my homemade avocado oil mayo, but whatever mayo you like will work just fine. It helps the crust stick and keeps the fish super moist.
• Lemon Juice – Totally optional, but I like to squeeze fresh lemon over the top right before serving for a little extra brightness.

Optional Veggies:

You don’t have to add veggies, but I usually do — it turns parmesan crusted tilapia into a super easy sheet pan meal. Here’s what I throw on the pan:

• Soft Veggies – I like using quick-cooking ones like zucchini, asparagus, green beans, or cherry tomatoes. Harder ones won’t cook in time.
• Olive Oil – I usually drizzle on olive oil, but avocado oil or melted butter work too — the cook time is short, so use whatever you’ve got.
• Sea Salt & Black Pepper – Just a sprinkle to season the veggies before they roast.

Sometimes I even roast parmesan Brussels sprouts alongside (just give them a head start before adding the fish).

How To Make Parmesan Crusted Tilapia

I have step-by-step photos here to help you visualize the recipe. For full instructions with amounts and temperatures, see the recipe card.

1. Season the fish. Lay the tilapia on a baking sheet, pat it dry, and sprinkle with garlic salt and pepper.
2. Add the mayo. Spread a thin layer of mayo over the top of each filet — it helps the topping stick and keeps the fish moist.

3. Make the topping. Mix the parmesan, oregano, basil, and paprika in a small bowl, then sprinkle it over each filet.
4. Toss on the veggies. If I’m making a full meal, I’ll add soft veggies around the fish. Just keep them in a single layer so they cook evenly.
5. Bake. Pop the parmesan crusted tilapia in the oven and bake until the fish flakes easily and the crust is golden. I like to squeeze some fresh lemon over the top before serving.

Serving Ideas

Not sure what to serve with parmesan crusted tilapia? Here are some of my favorite sides to round out the meal:

• Salads – When I want something fresh on the side, I usually make my kale crunch salad, but my creamy cucumber radish salad is a great option too.
• Vegetables – Like I mentioned above, I usually bake parmesan tilapia with veggies on the same pan, but you can definitely make sides separately too. Air fryer green beans and buttery sauteed broccoli are quick favorites — and I’m a big fan of sauteed eggplant with this one.
• Starches – Roasted potatoes or Instant Pot baked potatoes are always a hit (especially with my girls). But when I want something lighter, I’ll go for mashed cauliflower instead.
