Yes! Halibut is an ideal protein for the Mediterranean diet because it is lean, nutrient-dense, and pairs perfectly with plant-based ingredients like olive oil and vegetables.
Both work well. If using frozen, ensure the fish is completely thawed and patted dry with paper towels before roasting to ensure it sears properly rather than steaming.
While many enjoy butter-based sauces, a tomato-based sauce (like the one in this recipe) is a much heartier and healthier choice that provides moisture without high saturated fat.
The fish is done when it is opaque throughout and flakes easily with a fork. It should reach an internal temperature of 145°F.

Halibut is a nutrient-dense "superfood" of the sea, prized for its mild flavor and firm texture. Beyond being a high-quality protein, it is a significant source of selenium—a powerful antioxidant that helps reduce inflammation and supports heart health. It also contains niacin and magnesium, minerals essential for maintaining a steady heartbeat and improving circulation.
Recipe yields 6 servings
Lightly coat a medium pot with nonstick cooking spray and heat over low heat. Add garlic, anchovies and red-pepper flakes and cook, breaking up anchovies, until garlic is softened, 3 minutes. Add tomatoes and wine and increase heat to medium. Cook, stirring occasionally, until sauce thickens, about 20 minutes. Stir in olives and black pepper and simmer for 5 minutes.
Meanwhile, preheat oven to 425°.
In a bowl, toss potatoes and eggplant with oil, shallots and black pepper to taste. Spread mixture in a single layer in a 13 x 9-inch baking dish. Sprinkle salt over mixture and roast for 15 minutes. Turn potatoes and eggplant over and roast for 20 minutes longer, or until potatoes and eggplant are soft.
Remove baking dish from oven, add fish and season with black pepper. Place on bottom oven rack and roast until fish is just opaque in center, potatoes are golden brown and tender, and shallots are crispy, about 10 minutes.
Spoon sauce on plates before serving and top with fish and vegetables. Garnish with capers and parsley.
This dish is a complete meal on its own thanks to the included potatoes and eggplant. However, to stretch the meal further or add more fiber, consider serving it alongside a bowl of nutty whole grains or a crisp green salad with our creamy tzatziki dressing.
If fresh plum tomatoes aren't available, you can use one 28-ounce can of whole peeled tomatoes. Be sure to choose a "no salt added" variety to keep the sodium low.
If you cannot find halibut, other firm white fish like cod, sea bass, or snapper make excellent heart-healthy substitutes.
For those on a strictly low-sodium diet, rinse the olives and capers thoroughly under cold water to remove excess brine, or substitute with chopped artichoke hearts.
