Choosing Your Ingredients for the Best Flavor
Onions are key: Yellow onions bring a balance of sweetness and acidity, ideal for developing that classic French onion taste. You can experiment with sweeter onions, but the yellow onion’s flavor holds up nicely when sautéed.
French Onion Chicken Recipe
Ingredients
- 6 (4 oz.) skinless, boneless chicken breasts, raw
- 1/4 tsp paprika
- 1/4 tsp garlic powder
- 1/4 tsp seasoned salt
- 2 Tbsp Land o’Lakes light butter made with canola oil
- 1 yellow onion, peeled & sliced
- 1 cup beef broth
- 1 cup low sodium beef broth
- 1 tbsp apple cider vinegar
- 1/2 cup fat free or light mozzarella (I use Market Pantry reduced fat mozzarella)
Instructions
- Preheat oven to 350 degrees.
- In a skillet pan (or cast iron grill skillet) melt butter and add sliced onions. Sauté the onions in butter until softened and translucent.
- When onions become soft, place onions on a plate and set aside.
- Using the same skillet, spray the skillet with non stick cooking spray.
- Season each chicken breast with paprika, garlic powder, and seasoned salt. Place seasoned chicken breasts into prepared skillet.
- Cook for 5-7 minutes on medium high, on both sides or until chicken breasts are golden brown.
- Add onions back into the skillet with the chicken breasts.
- Pour in 1 cup beef broth and 1 cup beef broth. Add 1 tbsp apple cider vinegar. Simmer the chicken and onions for 2-3 minutes—this will allow the broth to caramelize the chicken.
- If using a cast iron skillet pan top each chicken breast with light mozzarella cheese. (Otherwise, transfer chicken, onions, and sauce into an oven safe baking dish—and top with light mozzarella cheese.)
- Place skillet or baking dish in preheated oven.
- Cook for 10-15 minutes or until bubbly.
Using both regular beef broth and low sodium beef broth allows flavor control. The regular broth adds richness, while the low sodium prevents the dish from becoming too salty, keeping the sauce balanced and savory.
Mozzarella cheese is mild and melts beautifully on top without overpowering the dish. For a more traditional twist, Gruyère or Provolone can be delicious options, adding a nuttier or sharper profile depending on your preference.
Essential Equipment for Success
A large, oven-safe skillet such as a cast iron or stainless steel pan is essential for searing the chicken and finishing the dish in the oven, achieving a perfect one-pan meal.
If you don’t own an oven-safe skillet, simply sear the chicken and onions in a regular skillet, then transfer everything to a 9×13 inch baking dish before baking.
The Secret to Perfect Onions
Softening the onions in butter until they are translucent is a must for building deep flavor. It’s not a full caramelization, but this step releases the onions’ natural sweetness and enhances the buttery richness essential to French onion chicken. Beginners, don’t worry—this is an easy step that really transforms the dish.
Tips for the Best French Onion Chicken
- Don’t overcrowd the pan when searing chicken to ensure a golden-brown crust.
- Make sure your skillet is hot before adding chicken to get that perfect sear.
- Use both beef broths to keep the sauce flavorful but balanced in salt.
- Let the chicken simmer briefly in the broth to thicken and deepen the sauce flavor.
Recipe Variations & Substitutions
| Substitution | Original Ingredient | Alternative & Notes |
|---|---|---|
| Chicken | Boneless, Skinless Chicken Breasts | Boneless, skinless chicken thighs can be used. They are more forgiving and won’t dry out as easily. Cook time may vary slightly. |
| Broth | Beef Broth & Low Sodium Beef Broth | You can use all regular beef broth, but be mindful of the final saltiness. Chicken broth can also work but will result in a lighter flavor. |
| Low-Carb | Natural sauce reduction | The sauce is naturally low-carb, but to make it thicker, you can create a slurry with 1/4 tsp of xanthan gum and 1 tbsp of cold water and whisk it in during the simmer. |
What to Serve with Your Dish
Pair this French onion chicken with creamy mashed potatoes, cheesy scalloped potatoes, or roasted green beans to soak up the rich sauce. Roasted green beans, or even ultimate roasted carrots, add a fresh, crisp contrast, and a crusty bread is perfect for mopping up every last bit.
Storage, Freezing, and Reheating
- Storing Leftovers: Keep in an airtight container in the fridge for up to 3 days.
- Making Ahead: Slice onions and prepare broth mixture in advance to save time.
- Reheating: Warm gently in the oven or stovetop to maintain the chicken’s tenderness and avoid rubberiness.
