Ingredients You’ll Need

• For Seasoning the Fish:
• 1 filet of fish (cod, tilapia, or halibut work well)
• 1 tsp paprika
• 1 tsp Italian seasoning
• 1 tsp Cajun or Old Bay seasoning
• ½ tsp red pepper flakes
• ½ tsp salt
• ¼ tsp black pepper
• 3 tbsp cooking oil
• For the Tomatoes and Olives:
• 2 cups cherry tomatoes
• ½ cup olives (Kalamata or green)
• 2 sprigs fresh parsley
• 2 sprigs fresh thyme
• 3 cloves garlic, minced
• 1 tsp reserved seasoning mix
• 2 tbsp water
• 3 tbsp salted butter
• A pinch of salt and pepper

Substitution Options

If you don’t have certain ingredients, no worries! Swap the fish for shrimp or chicken breast if seafood isn’t your thing. Use dried herbs instead of fresh ones—just reduce the amount by half since dried herbs are more potent. If you’re avoiding butter, olive oil works beautifully too. For those who aren’t fans of spicy food, skip the red pepper flakes and use mild seasoning blends instead. Flexibility is key here!

Step 1: Preheat and Prepare

Start by preheating your oven to 400°F (200°C). While the oven heats up, grab a small bowl and mix all the seasonings for the fish. Set aside 1 teaspoon of this blend for the tomatoes later. Rub the fish generously with the seasoning on both sides. Pro tip: Let the fish sit for a few minutes while you prep the other ingredients—it helps the flavors sink in.

Step 2: Sear the Fish

Heat the oil in a large oven-safe skillet over medium heat. Once hot, add the fish and sear for about 1 minute per side until golden brown. Don’t worry if it’s not fully cooked through—that’ll happen in the oven. Remove the fish and set it aside on a plate. The crispy exterior adds texture and locks in moisture, making every bite heavenly.

Step 3: Cook the Tomatoes and Olives

In the same skillet, toss in the cherry tomatoes, olives, garlic, and reserved seasoning. Stir everything together and cook for about 3 minutes until the tomatoes start to soften and release their juices. Their sweetness balances the salty olives perfectly. Imagine the sizzle and pop of these colorful ingredients—they smell divine already!

Step 4: Bake Everything Together

Place the fish back in the center of the skillet, nestling it among the tomatoes and olives. Dot the top with butter for richness, then transfer the skillet to the preheated oven. Bake for 10 minutes or until the fish flakes easily with a fork. Chef’s tip: Adding a splash of lemon juice before serving enhances the brightness of the dish.

Quick enough for a weeknight but elegant enough for company.

Chef’s Secret

Here’s a little trick: Pat the fish dry with paper towels before seasoning. Excess moisture can prevent that beautiful sear we’re aiming for. Also, don’t overcrowd the pan when cooking the tomatoes—they need space to caramelize slightly for maximum flavor.

Extra Info

Did you know that cherry tomatoes are packed with lycopene, an antioxidant linked to heart health? Pairing them with omega-3-rich fish makes this dish not only delicious but also a nutritional powerhouse.

Necessary Equipment

You’ll need a sturdy oven-safe skillet or baking dish, a cutting board, a sharp knife, and measuring spoons. If your skillet isn’t oven-safe, simply transfer everything to a baking sheet lined with parchment paper.

Storage Tips

To store leftovers, let the dish cool completely before transferring it to an airtight container. It keeps well in the fridge for up to 2 days. Reheat gently in the oven or microwave to preserve the fish’s texture. Avoid freezing, as the tomatoes may become watery upon thawing.

When reheating, sprinkle a bit of water over the fish to keep it moist. Never reheat more than once, as this can compromise the quality.

For meal prep enthusiasts, consider doubling the recipe. Portion it out with quinoa or roasted veggies for a complete lunchbox option.

Tips and Advice

• Choose fresh, firm fish fillets for best results.
• Use high-quality olives for a richer taste.
• Don’t skip the fresh herbs—they elevate the dish significantly.

Presentation Ideas

Garnish with extra parsley or a drizzle of olive oil for a pop of color. Serve alongside crusty bread to soak up the sauce or a bed of fluffy couscous. A wedge of lemon on the side adds a touch of elegance.

Healthier Alternatives

Try these variations to switch things up:

1. Baked Salmon Version: Use salmon fillets and swap olives for capers.
2. Low-Carb Option: Serve with zucchini noodles instead of grains.
3. Vegan Twist: Replace fish with tofu or chickpeas.
4. Spice-Lover’s Delight: Add extra red pepper flakes or harissa paste.
5. Herbaceous Touch: Experiment with rosemary or basil instead of thyme.
6. Mediterranean Mashup: Include artichoke hearts and sun-dried tomatoes.

Mistake 1: Overcooking the Fish

Fish cooks quickly, and overdoing it leads to dry, rubbery results. To avoid this, check for doneness after 8 minutes in the oven. The fish should flake easily but still feel moist. Pro tip: Use a meat thermometer—the internal temp should reach 145°F (63°C).

Mistake 2: Skipping the Sear

Searing might seem optional, but it’s crucial for locking in juices and creating a flavorful crust. Without it, the dish loses its depth. Make sure your skillet is hot before adding the fish.

Mistake 3: Using Dull Knives

Dull knives crush tomatoes instead of slicing them cleanly, releasing too much juice and making the dish soggy. Invest in a good knife and sharpen it regularly.
