French onion chicken is a riff on classic french onion soup. All of the delicious components of french onion soup are poured over pan-fried breaded chicken and baked in the oven to create a delicious, melt-in-your-mouth dinner.
I like to use yellow onions for their balance of sweet and pungent flavors. You can use also use sweet or white onions, or a mix of onions. I do not recommend using red onions.
Absolutely! Use an equal amount of boneless, skinless chicken thighs. You may need to increase the cooking time!
I recommend choosing a dry white wine. A dry white wine is any white wine that is not sweet. I like Sauvignon Blanc, Chardonnay, Riesling, or Pinot Grigio. You can also use white cooking wine, which can be found in the oil and vinegar aisle of the grocery store.
Recipe Tips and Tricks
Chicken naturally plumps up more when cooked, so be sure to pound it thin! You can also cut your chicken breasts in half horizontally to ensure the chicken cooks more quickly and evenly.
