Ingredients
Fish
4 (6-ounce) skinless white fish fillets, 1 inch thickKosher salt 4 ounces frozen artichoke hearts, thawed, patted dry, and sliced in half lengthwise1 tablespoon cornstarch ¾ cup olive oil 3 garlic cloves, minced½ onion, peeledVinaigrette
4 ounces cherry tomatoes ½ small shallot, peeled4 teaspoons sherry vinegar Kosher salt ½ teaspoon pepper 1 tablespoon chopped fresh parsley 2 ounces cherry tomatoes, cut into ⅛-inch-thick roundsBefore You Begin
Fillets of meaty white fish like cod, halibut, sea bass, or snapper work best in this recipe. Just make sure the fillets are at least 1 inch thick. A neutral oil such as canola can be substituted for the pure olive oil. The onion half in step 3 is used to displace the oil; a 4-ounce porcelain ramekin may be used instead. Serve with couscous or steamed white rice.
Instructions
- Adjust oven racks to middle and lower-middle positions and heat oven to 250 degrees. Pat fish dry with paper towels and season each fillet with 1/4 teaspoon salt. Let sit at room temperature for 20 minutes.
- Meanwhile, toss artichokes and cornstarch in bowl to coat. Heat 1/2 cup oil in 10-inch nonstick skillet over medium heat until shimmering. Shake excess cornstarch from artichokes and add to skillet; cook, stirring occasionally, until crisp and golden, 2 to 4 minutes. Add garlic and continue to cook until garlic is golden, 30 to 60 seconds. Strain oil through fine-mesh strainer into bowl. Transfer artichokes and garlic to ovenproof paper towel–lined plate and season with salt. Do not wash strainer.
- Return strained oil to skillet and add remaining ¼ cup oil. Place onion half in center of pan. Let oil cool until it registers about 180 degrees, 5 to 8 minutes. Arrange fish fillets, skinned side up, around onion (oil should come roughly halfway up fillets). Spoon a little oil over each fillet, cover skillet, transfer to middle rack, and cook for 15 minutes.
- Remove skillet from oven. Using 2 spatulas, carefully flip fillets. Cover skillet, return to middle rack, and place plate with artichokes and garlic on lower-middle rack. Continue to cook fish until it registers 130 to 135 degrees, 9 to 14 minutes longer. Gently transfer fish to serving platter, reserving 1/2 cup oil, and tent fish loosely with aluminum foil. Turn off oven, leaving plate of artichokes in oven.
- Process whole cherry tomatoes, shallot, vinegar, 3/4 teaspoon salt, and pepper with reserved 1/2 cup fish cooking oil in blender until smooth, 1 to 2 minutes. Add any accumulated fish juice from platter, season with salt to taste, and blend for 10 seconds. Strain sauce through fine-mesh strainer, pressing on solids to extract as much liquid as possible (discard solids).
- To serve, pour vinaigrette around fish. Garnish each fillet with warmed crisped artichokes and garlic, parsley, and tomato rounds. Serve immediately.

Why This Recipe Works
This restaurant-style dish requires a pot of pricey olive oil and promises super-moist, delicately cooked fish. Using a small skillet and flipping the fish halfway through allowed us to cut back to 3/4 cup of oil, which we employed to crisp flavorful garnishes and finally blended into a creamy vinaigrette.
