4 chicken leg quarters, cut in half at joint (about 3 pounds total)
Coarse salt and ground pepper
2 teaspoons vegetable oil
1 large yellow onion, halved and thinly sliced lengthwise
3 garlic cloves, roughly chopped
2 tablespoons sweet paprika
3 tablespoons all-purpose flour
1 3/4 cups low-sodium chicken broth
1 can (14 ounces) diced tomatoes
1/2 pound wide egg noodles
1/2 cup sour cream or thick plain yogurt
Parsley, for garnish, optional

Season chicken with salt and pepper. In a large Dutch oven or heavy pot, heat oil over high. Cook chicken, skin side down, until golden and crisp, 6 minutes. Flip chicken and cook until browned, 6 minutes more. Transfer to a plate. Discard all but 1 tablespoon fat from pot and reduce heat to medium. Add onion and cook, stirring frequently and scraping up any browned bits with a wooden spoon, until beginning to soften, 2 minutes. Add garlic and cook, stirring frequently, 3 minutes. Add paprika and flour, season with salt and pepper, and stir constantly until paprika is fragrant and mixture begins to stick, 1 minute. Add broth and whisk until smooth. Add tomatoes and bring to a boil over high. Return chicken to pot in a single layer, skin side up, and reduce heat to medium. Cover and cook until chicken is cooked through, 20 minutes. Meanwhile, in a large pot of boiling salted water, cook noodles according to package instructions. Drain noodles and divide among four bowls. Top with chicken. Remove pan from heat. Temper sour cream with a bit of the sauce, then stir sour cream into sauce, then ladle over chicken and noodles.
