Step-by-Step Instructions: How to Make Spanish Halibut

  1. Preheat the Oven

  4. Bake the Fish
    • Bake in preheated oven for 13–17 minutes depending on fillet thickness.
    • Thicker fillets may require closer to 15–17 minutes; thinner ones about 13 minutes.

  5. Finish and Serve
    • Remove from oven and garnish with freshly chopped basil.
    • Serve immediately with your choice of sides.
