Creating Pan-Seared Cod with Tomato Basil Sauce is straightforward if you follow these easy steps:

1. Prepare Ingredients: Rinse and pat dry the cod fillets. Season both sides with salt and pepper.
2. Heat Oil: In a large skillet, heat 2 tablespoons of olive oil over medium-high heat until shimmering.
3. Cook Cod: Add the cod fillets to the skillet, searing for about 4-5 minutes on one side until golden brown. Flip carefully and cook for another 3-4 minutes, until the fish is opaque and flakes easily.
4. Remove Cod: Transfer the cooked cod to a plate and cover to keep warm.
5. Make Sauce: In the same skillet, add minced garlic and sauté for about 30 seconds until fragrant.
6. Add Tomatoes: Add the diced tomatoes (with juices) to the skillet. Stir well and let it simmer for about 3-4 minutes.
7. Season Sauce: Stir in the chopped basil, balsamic vinegar, and optional crushed red pepper flakes. Cook for another 1-2 minutes.
8. Combine: Return the cod to the skillet, spooning some of the tomato basil sauce over the top. Allow it to heat through for about a minute.
9. Serve: Remove from heat and serve immediately.
