This tilapia with roasted pepper sauce turns ordinary fish into a fancy dinner without much work. The bold sauce gives depth to mild tilapia, making it something your family will ask for over and over.
I whipped up this tilapia dish when unexpected guests showed up and I had to make do with what was in my kitchen. Everyone thought I'd spent ages cooking because of the beautiful color and smooth texture of the sauce, when it only took me a few minutes.
What You'll Need
- Tilapia fillets: go for fresh if possible, but thawed frozen ones work great too
- Roasted red peppers: the jarred kind save you time and still taste amazing
- Heavy cream: gives that smooth, rich feel that makes the sauce so good
- Smoked paprika: brings a hint of smokiness that goes well with the sweet peppers
- Garlic: use real cloves for a flavor kick that powder just can't give
- Butter: pick unsalted so you can control how salty your dish is
- Olive oil: stops the butter from burning and adds its own light flavor
- Red pepper flakes: you can skip these, but they add a nice warmth without too much heat
- Fresh parsley: adds color and a fresh taste that lifts the whole dish
Cooking Tilapia with Roasted Pepper Sauce
- Prep Your Fish:
- Dry your tilapia completely with paper towels - this helps it brown nicely. Sprinkle lots of salt and fresh black pepper on both sides so it sticks well to the surface.
- Get a Nice Brown Crust:
- Warm up olive oil and butter in a big pan until the butter stops bubbling but isn't brown yet. Put the fish in without crowding and don't move it for 3-4 minutes until golden. Flip once and cook another 3 minutes until it breaks apart easily.
- Start Your Sauce:
- Using the same pan with all the tasty fish bits, add butter and garlic, cooking just until you can smell it, about a minute. Watch carefully since garlic burns fast and gets bitter.
- Mix the Peppers:
- Toss roasted peppers into the buttery garlic mix and let them warm up. Put everything in a blender and mix until totally smooth for the best texture. You can use a food processor too but it won't get quite as smooth.
- Complete the Sauce:
- Pour the pepper mix back in the pan, stirring the whole time as you add heavy cream. You'll see it turn a pretty coral-orange color. Add smoked paprika and red pepper flakes if you want, and let it bubble until it's thick enough to coat a spoon.
- Bring It All Together:
- Put the cooked tilapia back in the sauce, spooning the creamy mix over the fish. Let everything warm together for a minute or two before putting on plates. Sprinkle lots of fresh parsley on top.

The roasted red peppers really make this dish special. I got the idea after visiting Spain where I couldn't get enough of their romesco sauce. My quick version brings those sunny Mediterranean flavors to your table without much fuss, and always reminds me of that sunny vacation when I cook it.
Prep Ahead Ideas
You can make the roasted pepper sauce up to three days early and keep it in the fridge in a sealed container. This makes dinner super quick on busy nights - just cook the fish and heat the sauce. The flavors actually get better after a day of sitting, so it's perfect for making ahead. When you warm it up, you might need to add a little cream or broth since it gets thicker in the fridge.

Great Side Dishes
This tilapia works best with sides that go well with it but don't steal the show. Lemon garlic orzo soaks up the sauce perfectly and keeps that Mediterranean feel. If you want fewer carbs, try roasted asparagus or cooked zucchini for a fresh contrast to the rich sauce. For a fancier look, serve the fish on a bed of wilted spinach which looks pretty and adds healthy greens. The bright sauce also tastes amazing with a cold glass of Pinot Grigio or Chardonnay that balances the creaminess.
Making Your Own Roasted Peppers
Jarred peppers work fine in this recipe, but making your own adds extra smoky sweetness. To do it yourself, put whole bell peppers right on a gas flame or under the broiler, turning now and then until the skin gets completely black, about 10 minutes. Put them in a bowl covered with plastic wrap and let them steam for 15 minutes. The skins will pull off easily, and the taste difference is noticeable. That bit of char works really well with the smoked paprika in the sauce.
Frequently Asked Questions

Yep, frozen tilapia works just fine! Just be sure to thaw it completely and pat it dry before you start cooking for the perfect sear.

Char whole red peppers on an open flame or bake them in the oven until the skin turns black. Let them cool in a covered bowl, peel the charred parts off, and remove seeds. They're ready to use!
