Roasted Tilapia with Caramelized Onion and Lemon

Instructions

1. 1

   Preheat your oven to 400°F (200°C). While it heats, prepare a large baking sheet by lining it with parchment paper or lightly oiling it.

   Tip: Parchment paper prevents sticking and makes cleanup easier.

2. 2

   Heat 3 tablespoons of olive oil in a large skillet over medium heat. Add the sliced onions and cook for 8-10 minutes, stirring occasionally, until they begin to soften and turn golden brown.

   Tip: Don't rush the onions; low and slow cooking creates natural sweetness.

3. 3

   Add the minced garlic to the softened onions and cook for another 2 minutes until fragrant. Stir in the vegetable broth and balsamic vinegar, then continue cooking for 3-4 minutes until the onions are deeply caramelized and the liquid mostly reduces.

   Tip: The broth adds depth while the vinegar balances the sweetness.

4. 4

   Arrange the tilapia fillets on the prepared baking sheet in a single layer. Season each fillet with salt, pepper, and fresh thyme on both sides.

   Tip: Pat the fillets dry before seasoning so they roast better.

5. 5

   Drizzle the remaining 2 tablespoons of olive oil and the fresh lemon juice over the tilapia fillets.

   Tip: The lemon juice will infuse flavor as the fish roasts.

6. 6

   Spoon the caramelized onion mixture evenly over each tilapia fillet, dividing it equally among the four portions.

   Tip: Leave some onions to spoon over the top for an attractive presentation.

7. 7

   Place the baking sheet in the preheated oven and roast for 12-15 minutes, until the tilapia is opaque and flakes easily with a fork.

   Tip: Avoid overcooking; tilapia cooks quickly and becomes dry if left too long.

8. 8

   Remove from the oven and transfer each fillet to a serving plate. Garnish with fresh lemon slices and any remaining thyme, then serve immediately while hot.

   Tip: Serve with roasted vegetables or a light salad for a complete meal.
