Garlic and Tomato Tilapia

Ingredients

  • cloves garlic, crushed
  • cup peeled, seeded, and diced tomato
  • tablespoons sour cream
  • salt and pepper to taste
  • tilapia fillets

Instructions

  1. Step 1

    Preheat your oven to 325°F (165°C). In a mixing bowl, combine the crushed garlic and diced tomato. Using a fork, mash them together until the garlic is well blended into the tomato. Stir in the sour cream, then season generously with salt and pepper. I like to taste the sauce at this stage—it should be tangy and slightly sharp from the garlic. Place the tilapia fillets in a shallow baking dish. Slide them into the oven and bake for 10 minutes. The fish will turn opaque and begin to flake. Carefully remove the dish, then spoon the tomato-garlic mixture evenly over each fillet, letting some pool around. Return to the oven for another 10 to 12 minutes, until the fish is cooked through and flakes easily with a fork. The sauce will be bubbly and tempting. I sometimes broil for an extra minute to get a few golden spots. Serve the tilapia with the creamy sauce spooned over the top. A squeeze of lemon adds brightness, but it’s lovely as is.

Chef's Tip

For an extra layer of flavor, I quickly sauté the garlic in a bit of olive oil before mixing it with the tomato. This mellows the garlic and adds a subtle nuttiness to the sauce. Just cool it slightly before stirring into the sour cream.

Storage Tips

Store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently in the microwave or a covered skillet with a splash of water to keep the fish moist.

Variation Tips

For a dairy-free option, use coconut cream instead of sour cream. Scatter capers and lemon slices over the fish before broiling for a Mediterranean twist. This dish pairs beautifully with steamed green beans or cauliflower rice. For crunch, top with toasted almonds.
