What You’ll Need
Here’s everything you’ll need to make this easy French Onion Chicken Bake:
- 4 boneless, skinless chicken breasts (about 1¾ pounds)
- 1 teaspoon salt, divided
- ½ teaspoon ground black pepper
- ½ cup all-purpose flour
- 2 tablespoons olive oil
- 1 tablespoon salted butter
- 2 large yellow onions, thinly sliced
- 2 cloves garlic, minced
- 1½ cups beef broth
- 2 teaspoons Worcestershire sauce
- 1 teaspoon fresh thyme leaves, chopped
- 4 ounces gruyère or Swiss cheese, grated
Pro Tips
Before you get started, here are a few tips from my own kitchen that’ll make this recipe a breeze:
- Pound the Chicken for Even Cooking: To make sure your chicken cooks evenly and stays juicy, pound the breasts to an even thickness. It makes a big difference!
- Caramelize Slowly: Don’t rush the onions. The longer they cook, the sweeter and more flavorful they get. It might take 20-25 minutes, but it’s totally worth it.
- A Little Wine Never Hurt: If you’re feeling fancy, a splash of red wine can really elevate the flavor when you deglaze the pan. But if you’re not into wine, just use extra beef broth.
- Use a Cast Iron Skillet: If you have one, a cast iron skillet is perfect for this dish. It gives great heat distribution, and you can go straight from stovetop to oven without any issues.
- Let it Rest: After baking, give the chicken a few minutes to rest. This helps lock in all those juices for a super tender bite.
Tools You’ll Need
Here’s a quick rundown of the tools I use to make this easy French Onion Chicken Bake:
- A large oven-safe skillet (preferably cast iron)
- A meat mallet or rolling pin to pound the chicken
- A sharp knife and cutting board
- A wooden spoon or spatula
- Oven mitts (because we’re working with hot pans!)
Substitutions and Variations
This dish is super flexible, so feel free to get creative. Here are a few substitutions and variations you can try:
- Cheese: If you’re not a fan of gruyère, Swiss cheese or even mozzarella works great here. Go with what you like!
- Herbs: If you don’t have fresh thyme, you can use dried thyme—just half the amount since dried herbs are more concentrated.
- Wine: Red wine adds depth, but if you’re not into it, extra beef broth is a great alternative.
- Chicken: You can swap out the chicken breasts for bone-in thighs, but just make sure to adjust your cooking time.
Make-Ahead Tips
Sometimes it’s nice to have things ready to go before you actually cook. Here are a few make-ahead tips:
- Onions: You can caramelize the onions ahead of time and store them in the fridge for up to 3 days.
- Fully Assembled: You can prep the whole dish (without baking) and store it in the fridge for 24 hours. Just pop it in the oven when you’re ready.
- Freezing: If you have leftovers, you can freeze the chicken bake for up to 3 months. Just make sure it’s well wrapped and store it in an airtight container.
Instructions
Now, let’s get cooking! Here’s how you make this French Onion Chicken Bake:
- Preheat the Oven: Start by preheating your oven to 400°F (200°C).
- Prep the Chicken: Season your chicken breasts with ½ teaspoon of salt and pepper, then dredge them in flour. Shake off any excess.
- Sear the Chicken: Heat the olive oil in a large oven-safe skillet over medium-high heat. Add the chicken and cook for 6-7 minutes on each side until golden brown. Remove the chicken and set it aside.
- Caramelize the Onions: In the same skillet, melt the butter. Add your onions and cook, stirring occasionally, for 20-25 minutes, until they’re beautifully caramelized and brown.
- Add Garlic and Thyme: Toss in the garlic and thyme, cooking for 1-2 minutes until fragrant.
- Deglaze: Pour in a splash of red wine (if you’re using it) and scrape up any brown bits stuck to the skillet. Let it cook down for 2-3 minutes.
- Combine Everything: Put the chicken back in the skillet and pour in the beef broth and Worcestershire sauce. Bring it to a simmer.
- Top with Cheese: Sprinkle the grated cheese on top of the chicken and onions.
- Bake: Transfer the skillet to the oven and bake for 10-15 minutes, or until the cheese is melted and bubbly.
- Rest and Serve: Let the dish rest for a few minutes before serving. It’ll help everything come together perfectly.
