Chicken with Lemon, Tomatoes and Onions

Timeabout 20 minutes

Ingredients

Directions

Prepare

Squeeze the lemon thoroughly, then remove the seeds from the juice.
Marinate the chicken in lemon juice with pepper and basil (as much as you can afford) until you need it.

Brown the onions and chicken

Sauté the onions and garlic in a little butter over high heat until golden brown and tender, then remove them to a plate.
In the same skillet, with a bit more butter, sear the chicken on both sides until brown.
Return the onions and garlic to the skillet and turn down the heat.
Add a tablespoon of butter.

Simmer and serve

Stir in the mustard, vinegar, and lemon juice.
Add the tomatoes and a lot of pepper.
Cover the skillet and simmer until the chicken is no longer pink (about 20 minutes).
Serve over couscous.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Chicken thighs and drumsticks: Provides the main protein, which firms and turns opaque as it cooks through.
Onions: Soften and turn sweet and golden when sautéed, adding depth to the sauce.
Lemon: Its juice adds acidity that brightens the dish and tenderizes the chicken during marinating.
Tomatoes: Break down during simmering to add moisture and a fresh, tangy body to the sauce.
Mustard: Adds sharp flavor and helps emulsify the pan liquids into a smoother sauce.
Butter: Adds fat for browning the onions and chicken and a rich flavor to the sauce.

The step that matters

Searing the chicken until well browned. Browning builds flavor through the Maillard reaction, which needs dry surfaces and high heat. Crowding the pan or moving the chicken too early steams it instead, leaving the sauce flat and pale.
