My family turns to this filling Tilapia in Roasted Pepper Sauce whenever we want something that's both light and totally satisfying. The tender fish works so well with the bold, smoky sauce, giving you a meal that feels fancy without taking forever to make.
I whipped this up when I was bored with the usual lemon and herb fish dishes. The pepper sauce was such a big hit that my family now asks for it at least twice every month.
What You'll Need
- 4 tilapia fillets: Go for firm pieces with a fresh smell and bright eyes if buying whole
- 2 red bell peppers: Pick ones that seem heavy and have shiny skin
- 1 small onion: White or yellow ones add just the right sweetness
- 2 cloves garlic: Use fresh for the strongest taste
- 1 tablespoon olive oil: Extra virgin gives better flavor
- 1 cup vegetable or chicken broth: Try making your own for a tastier sauce
- 1 tablespoon balsamic vinegar: Adds depth and cuts the sweetness
- 1 teaspoon smoked paprika: Gives that amazing smoky flavor
- 1 teaspoon dried oregano: The Mediterranean type packs more punch
- Salt and pepper: Add to your liking
- Fresh parsley: Sprinkle on top for color and freshness
Tasty Preparation Steps
- Get Those Peppers Roasted:
- Heat your oven to 400°F and put the whole peppers on a baking sheet. Let them cook about 20 minutes until they're black and bubbly all around. Flip them once so they char evenly. The darker they get, the smokier your sauce will taste without turning bitter.
- Make Them Easy to Peel:
- Put the hot peppers in a bowl and cover with a dish towel or plastic wrap. Let them sit for 10 minutes to soften the skin. Then pull off the blackened skin with your fingers. Cut out the stems and seeds. A little water helps wash away any stubborn seeds.
- Cook the Flavor Base:
- Warm olive oil in a pan over medium heat until it looks shimmery. Throw in your chopped onion and stir now and then for 4-5 minutes until they turn clear and soft. Add your chopped garlic and cook just another minute until it smells good. Keep an eye on it since garlic burns fast.
- Mix Up Your Sauce:
- Toss your cleaned peppers in the pan with broth, balsamic vinegar, smoked paprika, and oregano. Let it bubble gently for 5-7 minutes. The liquid will cook down a bit and the flavors will get stronger. Add salt and pepper until it tastes just right.
- Smooth It Out:
- Pour everything into a blender or use a stick blender right in the pan to make the sauce smooth as silk. A powerful blender makes it extra velvety. Pulse a few times then blend until completely smooth. Keep it warm on low heat if needed.
- Get the Fish Ready:
- In the same pan, heat a little more olive oil over medium-high heat. Season both sides of your tilapia with salt, pepper, and a tiny bit of smoked paprika. Cook them for 3-4 minutes per side. The fish is done when it looks white all through and flakes easily with a fork.
- Dish It Up:
- Ladle plenty of pepper sauce onto each plate. Place the cooked tilapia on top and spoon a bit more sauce over it. Scatter fresh chopped parsley on top just before you serve it for pretty color and fresh flavor.

Smoked paprika really makes this dish special. I found out how amazing it is during a trip to Spain where they use it all the time with seafood. Even my kids who usually say no to fish clean their plates when I make this sauce.
Prep Ahead Ideas
The dish gets even better when you do some work beforehand. You can make the roasted pepper sauce up to three days early and keep it in the fridge in a sealed container. The flavors actually get richer during this time. When you're ready to eat, just warm up the sauce slowly while cooking fresh fish. This trick has helped me enjoy countless dinner parties instead of being stuck in the kitchen.
What to Serve With It
This tilapia dish goes great with simple sides that don't fight for attention. I love serving it with lemon-flavored quinoa or couscous that soaks up the extra sauce. For a complete meal with Mediterranean vibes, add some quick garlic spinach or steamed asparagus with a squeeze of lemon. My husband says the must-have item is crusty bread for sopping up every drop of sauce—that's his favorite part.
Swap These Ingredients
Though I made this for tilapia, any mild white fish does the job well. I've tried it with sole, flounder, and even fancy sea bass for special dinners. The sauce works with different peppers too—yellow or orange bells make it sweeter and milder, or add a small hot pepper if you want some kick. Want a creamier dairy-free version? Blend in some soaked cashews. If you don't eat meat, try pouring this same sauce over grilled portobello mushrooms or roasted cauliflower slices for an equally tasty meal.
Food Heritage
This meal borrows from Mediterranean cooking styles, especially Spanish and Italian traditions where peppers show up in lots of seafood dishes. The mix of sweet peppers, smoky paprika, and tangy balsamic creates something like romesco sauce from Catalonia, often served with fish. Along the Spanish coast, folks make similar dishes, particularly in summer when peppers taste their best. I first tried something like this while traveling through tiny fishing villages on the Mediterranean where local cooks focus on letting fresh ingredients shine.
