COOKING SLICED POTATOES IN OVEN RECIPES

Steps:

• Heat oven to 400 degrees. Peel potatoes, and cut them into slices about 1/8-inch thick (a mandoline comes in handy here). Toss the potatoes in an 8-by-12-inch or similar size baking pan with 4 tablespoons of the oil or butter. Season the potatoes liberally, spread them evenly and place the pan in the oven.
• Cook for about 40 minutes, checking once or twice, until the potatoes are tender when pierced with a thin-bladed knife and have begun to brown on top. Remove the potatoes from the oven. Turn on the broiler, and adjust the rack so that it is 4 to 6 inches from the heat source.
• Top the potatoes with the fish, drizzle with the remaining oil or butter and sprinkle with some more salt and pepper. Broil until the fish is done, 6 to 10 minutes, depending on its thickness (a thin-bladed knife will pass through it easily). If at any point the top of the potatoes begins to burn, move the pan a couple of inches farther away from the heat source.

Steps:

• Season steak generously with salt and pepper. Sprinkle with sliced garlic and rosemary and set aside to marinate, 20 to 30 minutes.
• Heat oven to 450 degrees. Meanwhile, bring a pot of well-salted water to a boil. Add potatoes and cook at a brisk simmer until just done, 10 to 15 minutes. Drain and keep warm.
• Heat a cast-iron or other heavy skillet over high heat. Remove and discard sliced garlic from steak. (If left on, it will burn in the skillet.)
• When pan is hot, put in the steak and let brown well on one side, 4 to 5 minutes. Wait until steak forms a crust and comes away cleanly from the bottom to move it.
• Flip steak and transfer pan to oven, uncovered. Roast until juices begin to rise on surface of steak (you will see the droplets) and internal temperature is 120 degrees, 8 to 10 minutes. Remove steak from pan and let rest, tented with foil, for 5 to 10 minutes. (Residual heat will continue to cook the meat to medium-rare as it rests.) Warm a serving bowl for the potatoes and plates for the steak.
• Melt butter in a wide skillet over medium-high heat. Add potatoes and toss to coat and heat through. Sprinkle with salt and pepper. Add minced garlic and cook, stirring, until softened but not browned, 1 minute or less. Gently stir in parsley and lemon zest and transfer to serving bowl.
• Cutting on a slight diagonal, slice steak into 1/2-inch slices, then transfer to plates. If using, place a handful of greens next to the steak. Serve immediately, passing potatoes at the table.
