BAKED VIDALIA ONIONS

Steps:

GREEK BAKED FISH WITH TOMATOES AND ONIONS

Steps:

• Pat the fish dry and season to taste with salt and pepper. Oil one or two baking dishes large enough to accommodate the fish in one layer. Lay the fish in the dish and pour on the lemon juice. Refrigerate for 30 to 60 minutes while you prepare the remaining ingredients.
• Preheat the oven to 375 degrees. Heat the oil over medium heat in a large, heavy skillet and add the onions. Cook, stirring often, until they have softened and begun to color slightly, 8 to 10 minutes. Add a generous pinch of salt and the garlic and cook, stirring, until the garlic is fragrant, 30 seconds to a minute. Stir in the tomatoes, sugar, paprika, cinnamon, dissolved tomato paste, wine, half the parsley and more salt and pepper to taste and bring to a simmer. Simmer uncovered, stirring often, until the sauce has cooked down a bit and is very fragrant, about 15 minutes. Remove from the heat and pour over the fish. Sprinkle on the remaining parsley.
• Place in the oven and bake until the fish is opaque and pulls apart easily with a fork, about 30 minutes. Baste the fish every 10 minutes if it is not submerged in the sauce. Serve hot or warm, with rice, bulgur, or potatoes.

BAKED COD WITH TOMATOES AND ONIONS

Steps:

• Preheat the oven to 400 degrees F.
• Place the fish in a large colander and rinse under cold running water. Place in a large non-reactive baking dish, and make 5 horizontal 3-inch slits on each side. Season the fish on both sides with 2 tablespoons olive oil, 3 teaspoons kosher salt, and 1/2 teaspoon black pepper.
• In a mixing bowl, toss together the sliced tomatoes, onions, garlic, remaining 1 tablespoon olive oil, 1 teaspoon kosher salt, and 1/2 teaspoon black pepper. Set aside until needed.
• Place the fish, skin side down, in a roasting pan. Thickly coat the top side of the fish with the olive spread. Layer the tomatoes and cilantro flat on top of the tapenade like scales, then top with the onions and garlic. Place the fish in the oven and bake until the juices run clear and the onions are beginning to crisp and slightly blacken along the edges, about 20 minutes.
• Remove the fish from the oven and let rest for 15 minutes. Place the fish on a platter and serve, garnished with cilantro sprigs.

Whisk heavy cream and cornstarch together in a small bowl. Stir gently into the sauce in the skillet. Place chicken back into the skillet and spoon some of the sauce over the chicken.
• Return skillet to the oven and bake, uncovered, until the chicken is no longer pink at the bone and the juices run clear, and an instant-read thermometer inserted near the bone reads 165 degrees F (74 degrees C), about 15 minutes more. Serve chicken and apples with the sauce.

Place seasoned thighs in the skillet and cook until browned, about 3 minutes. Turn thighs and brown the other side, about 2 minutes. Transfer browned thighs to a plate and keep warm.
• Add remaining 1 tablespoon olive oil to the same skillet. Add mushrooms; cook and stir for about 2 minutes. Add smashed garlic cloves and herbes de Provence; cook and stir for 1 more minute.
• Move mushrooms to one side of the skillet and place 3 onion slices into the skillet. Place a browned chicken thigh on top of each onion slice. Move mushrooms to create an empty space in the skillet, and place the remaining onion slices and chicken thighs in the skillet.
• When all the onion slices and chicken thighs are placed, redistribute the mushrooms evenly around the skillet. Pour white wine over all and cover.
• Transfer skillet to the preheated oven and bake until chicken thighs are no longer pink in the center and the juices run clear, about 15 minutes. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).

BALSAMIC-BAKED ONIONS AND POTATOES WITH ROAST PORK

Steps:

• Preheat the oven to 400 degrees F. Put the potatoes into a pan of boiling, salted water and cook for around 8 minutes, then drain and return to the pan. Chuff them up a bit by shaking the pan.
• To prepare the meat, scatter a handful of finely chopped rosemary leaves over a large chopping board. Sprinkle over some salt and pepper and the ground fennel seeds. Roll the pork across the board, pressing down hard so all the flavorings stick to it.
• Get a large roasting pan that your pork will fit snugly into, and place it on a burner over a medium-high heat. Pour in a little olive oil and place the pork in, fat side down, sprinkled with any flavorings remaining on the board. After a few minutes, when the pork fat is lightly golden, turn it over and add the garlic cloves, onion, celery and bay leaves to the pan. Place on the bottom shelf of your preheated oven for 1 hour, basting it halfway through. (For the last 20 minutes of cooking, you may need to cover the pork with a bit of damp waxed paper to stop it coloring too much.)
• Get another roasting pan, into which you can fit the potatoes in 1 layer, and heat it on the stove. When hot, pour a glug of olive oil into it and add the butter, rosemary and garlic. Add the potatoes and toss them in all the flavors. Add the onions and all the balsamic vinegar and season with salt and pepper. Cook for 5 minutes on the burner to reduce the balsamic vinegar a little. Place the pan on the top shelf and cook for around 50 minutes, until the potatoes and onions are dark, sticky and crispy - removing the pan to toss the onions and potatoes halfway through.
• After 1 hour, the meat should be cooked. Prick it with a sharp knife - if the juices run clear, it's done; if not, pop it back in the oven for another 10 to 15 minutes, keeping the potatoes warm. Remove it from the oven and let it rest on a plate for 10 minutes. Pour away most of the fat from the pan and mash up the garlic and onion. Place the pan over the burner and add the white wine. Simmer until the liquid has reduced by half, scraping all the meaty, marmitey goodness off the bottom to make a tasty little sauce, and season if necessary. Pass through a sieve into a serving pitcher. Then slice the pork and serve it with your incredible baked onions and potatoes, drizzled with the pan juices. This meal goes great with some nice greens or an arugula salad.
