Ingredients
4 boneless, skinless chicken breasts (about 2 pounds total)
1 (10.5-ounce) can condensed French onion soup
1 cup shredded Swiss or Gruyère cheese (or a blend)
1 tablespoon olive oil (or melted butter)
Salt and black pepper, to taste
Directions
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with a bit of the olive oil or nonstick spray.
Pat the chicken breasts dry with paper towels, then season both sides lightly with salt and black pepper.
Heat the olive oil in a large skillet over medium-high heat. Sear the chicken for 2–3 minutes per side, just until lightly browned. (This step adds flavor but you can skip it if you’re in a hurry.)
Place the chicken breasts in a single layer in the prepared baking dish.
Pour the condensed French onion soup evenly over the chicken, making sure each piece is coated and there’s some soup in the bottom of the dish.
Cover the baking dish tightly with foil and bake for 20 minutes.
Remove the foil, carefully stir or spoon some of the soup over the tops of the chicken, then sprinkle the shredded Swiss or Gruyère cheese evenly over each piece.
Return the dish to the oven, uncovered, and bake for another 10–15 minutes, or until the chicken is cooked through (internal temperature reaches 165°F/74°C) and the cheese is melted and bubbly.
Let the chicken rest for 5 minutes before serving so the juices settle. Spoon some of the oniony sauce from the pan over each piece when you plate it.
Variations & Tips
For picky eaters, you can use a milder cheese like mozzarella or provolone instead of Swiss or Gruyère, which can be a bit strong for some kids. If your family prefers darker meat, swap the chicken breasts for boneless, skinless chicken thighs and add a few extra minutes to the baking time if needed. To stretch the meal, tuck a layer of sliced onions or even canned mushrooms under the chicken before baking (this adds another vegetable without much extra effort). If you’d like a little crunch, sprinkle some seasoned breadcrumbs over the cheese for the last 5–10 minutes of baking. For a lower-sodium version, look for reduced-sodium French onion soup and season the chicken very lightly with salt. You can also turn this into a freezer meal: assemble the seasoned chicken and soup in a freezer-safe dish, cover well, and freeze; when you’re ready to bake, thaw in the fridge overnight, then bake as directed and add the cheese near the end. And if you have a slow cooker, you can adapt this by cooking the seasoned chicken and soup on LOW for 4–5 hours, then transferring to a baking dish, topping with cheese, and broiling just until melty and golden.
