Ingredients

Fish
4 (6 ounce) skinless white fish fillets, 1 inch thick
4 ounces frozen artichoke hearts, thawed, patted dry, and sliced in half lengthwise
1T cornstarch
3/4C olive oil
3 garlic cloves, minced
1/2 onion, peeled
Vinaigrette
4 ounces cherry tomatoes
1/2 small shallot, peeled
4t sherry vinegar
kosher salt
1/2t pepper
1T chopped fresh parsley
2 ounces cherry tomatoes, cut into 1/8" rounds

Steps:

1. FOR THE FISH: 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 1/4t salt. Let sit at room temperature for 20 minutes. 2. Meanwhile, toss artichokes and cornstarch in bowl to coat. Heat 1/2C 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, 2-4 minutes. Add garlic and continue to cook until golden - 30-60 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. 3. Return strained oil to skillet and add remaining 1/4C 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 15 minutes. 4. Remove skillet from oven. Using two spatulas, flip fillets carefully. Cover skillet, return to middle rack, and place plate with garlic and artichokes on lower-middle rack. Continue to cook fish until 130-135 degrees, 9 - 14 minutes longer.. Gently transfer fish to serving platter, reserving 1/2 C oil, and tent fish loosely with aluminum foil. Turn off oven, leaving artichokes in oven. 5. FOR THE VINAIGRETTE: Process whole cherry tomatoes, shallot, vinegar, 3/4t salt and pepper with reserved 1/2C fish cooking oil in blender until smooth, 1-2 minutes. Add any accumulated fish juice from platter, season with salt to taste, and blend 10 seconds. Strain sauce through fine-mesh strainer, pressing on solids to extract as much liquid as possible (discard solids). 6. To serve, pour vinaigrette around the fish. Garnish each fillet with warmed crisped artichokes and garlic, parsley, and tomato rounds.
