Good fish, good sauce, good Lord, let's eat.
Pat the tilapia fillets dry with a paper towel. Salt and pepper them with fresh ground pepper and let them sit a few minutes while you make the sauce.
Heat a cast-iron skillet over medium heat. Add the butter and olive oil, then sautΓ© the onion until soft. Add the garlic and cook about 30 seconds until it smells good.
Pour in the can of cherry tomatoes and use a slotted spatula to gently mash about ΒΌ of the tomatoes to start building the sauce.
Stir in the smoked paprika, capers, and a little fresh ground black pepper.
Lay the tilapia fillets right on top of the sauce. If you've got a lid for your skillet, put it on.
Cook about 3 minutes, then flip the fillets and cook about 3 minutes more, until the fish flakes easily.
Drizzle 1β2 teaspoons of lemon juice over the fish and sauce and sprinkle with parsley.
Right before serving, add one small knob of butter and gently swirl the pan until the sauce turns glossy.
Serve the fish and sauce over the parboiled rice and spoon plenty of sauce on top.
