Baked Halibut with Cherry Tomatoes

Halibut has a firm, meaty flake that holds up remarkably well in the oven, especially when paired with simple aromatics that let the fish stay center stage. In this recipe, halved cherry tomatoes break down as they roast, releasing their juices to mingle with minced garlic, olive oil, and dried oregano. The entire preparation comes together in a single baking dish with minimal prep work. Once in the oven at 400°F, the tomatoes soften and sweeten while the fillets cook through gently, creating a fragrant pan sauce that is ready to serve right away.
Why this one works
- Halibut bakes into firm, tender flakes without drying out easily.
- Cherry tomatoes release rich, sweet pan juices as they blister in the oven.
- Requires only ten minutes of active preparation before baking.
- Garlic, olive oil, and oregano create a fragrant, savory seasoning base.
- Cooks entirely in one baking dish for easy cleanup.

What you’ll need
- 2 fillets (340g) fresh halibut Choose fresh, firm fillets of uniform thickness so they bake through evenly in the dish.
- 2 cups (300g) cherry tomatoes, halved Halving the tomatoes allows their natural juices to release around the fish as they roast.
- 2 tablespoons (30ml) extra virgin olive oil Drizzled over the top to keep the fish moist and help the aromatics bloom in the oven heat.
- 2 cloves (10g) garlic, minced Finely minced garlic spreads evenly over the fillets and surrounding tomatoes for balanced flavor.
- 1 teaspoon (5g) dried oregano Provides an earthy, herbaceous note that complements the sweet roasted tomatoes.
