Based on a cheesy, creamy gratin, this dish will have your waistline thanking you. This gratin is light, with no cream or cheese in sight, just flavored with fresh herbs.
Sweet potatoes are sliced thin, covered with oil and rosemary then baked.
The halibut is quickly sautéed stove top, then placed on top of the sweet potatoes. Halibut is my favorite fish. With it’s beautiful, meaty white flesh is remarkably delicate but still weighty on the palette, it works very well with the creamy sweet potatoes. If you cannot find halibut any of your favorite firm fish would work, cod, sea bass, even salmon, so the choice is yours.
The halibut is topped with chopped tomatoes, fresh basil, kalamata olives and fresh lemon zest. If you are not a fan of olives, you can omit them from the recipe. The dish is then baked for 8-10 minutes until fully cooked. This is a lovely, light and healthy, quick meal.
