Here are some helpful conversions: - 1 tablespoon = 3 teaspoons - 1 cup = 8 fluid ounces - 1 teaspoon = 5 milliliters - 2 tablespoons = 1 ounce - 1 pound = 16 ounces These conversions can help you adjust the recipe easily. Feel free to mix and match ingredients to suit your taste! {{ingredient_image_1}} To start, grab a large skillet. Heat two tablespoons of olive oil and two tablespoons of butter over medium heat. Once the butter melts, add two large onions that are thinly sliced. Cook the onions for about 15 to 20 minutes. Stir them often. You want them to turn caramelized and a nice golden brown. Near the end, add three cloves of minced garlic. Cook for one to two more minutes until it smells great. Now, let's prepare the chicken. Take four boneless, skinless chicken breasts and season them well. Use salt, pepper, and one teaspoon of fresh thyme leaves. Push the cooked onions to the side of the skillet. Place the chicken breasts in the center. Cook each side for about five minutes. You want the chicken to brown nicely. Next, pour in one cup of beef broth and one tablespoon of balsamic vinegar. This adds a rich flavor. Make sure to scrape the bottom of the skillet. This helps release all those tasty bits stuck to the pan. Bring the mixture to a gentle simmer. Cover the skillet and lower the heat. Let it cook for about 15 to 20 minutes. The chicken should reach an internal temperature of 165°F to be fully cooked. To get sweet, golden onions, start with medium heat. Use olive oil and butter for rich flavor. Stir the onions often. This helps them cook evenly. Aim for about 15 to 20 minutes. If they stick, add a splash of broth. This also helps lift the tasty bits from the pan. Keep going until they are soft and brown. To keep chicken moist, start with boneless, skinless breasts. Season them well with salt and pepper. Searing the chicken helps lock in juices. Cook it for about 5 minutes on each side. Make sure the heat is not too high. This prevents burning while keeping the inside juicy. After adding broth, cover the skillet. This keeps the steam in, making the chicken tender. For the best cheese melt, use Gruyère. It has a nice, creamy texture. After cooking, sprinkle it over the chicken. Cover the pan again for 2 to 3 minutes. This allows the cheese to get gooey and delicious. If you want more flavor, try adding a sprinkle of garlic powder or a dash of paprika before melting. Enjoy the cheesy goodness! Pro Tips Caramelization is Key: Make sure to cook the onions slowly over medium heat to achieve the perfect caramelization. This brings out their natural sweetness and enhances the dish's flavor. Deglaze for Depth: When adding the beef broth, don't forget to scrape the bottom of the skillet. This will lift the flavorful brown bits, adding depth to your sauce. Use a Meat Thermometer: To ensure your chicken is perfectly cooked, use a meat thermometer to check for an internal temperature of 165°F. Experiment with Cheese: While Gruyère is traditional, feel free to mix in other cheeses like Swiss or provolone for a unique twist on flavor. {{image_2}} To make a vegetarian version, swap the chicken for hearty mushrooms. Use portobello or cremini mushrooms for great flavor. Sauté them just as you would the chicken. They will soak up the broth and balsamic vinegar nicely. You can also add extra vegetables like bell peppers or zucchini for more texture. For a gluten-free dish, replace beef broth with a gluten-free version. Many brands offer gluten-free broth that works well. Always check the label to ensure it fits your needs. You can also use cornstarch or arrowroot to thicken the sauce if needed. To elevate the taste, try adding a splash of white wine along with the broth. This adds depth and richness. Fresh herbs like rosemary or sage can give a unique twist too. For a spicy kick, sprinkle in some red pepper flakes while cooking the onions. These small changes can make your dish stand out. After enjoying your French onion chicken, cool it down to room temperature. Place the chicken in an airtight container. Store it in the fridge for up to three days. Make sure to keep the onions and cheese with the chicken. This way, you keep all the great flavors together. To reheat, you can use a skillet or the microwave. If using a skillet, add a splash of broth to keep it moist. Heat over medium-low until hot. For the microwave, place the chicken on a plate. Cover it with a damp paper towel. Heat for 1-2 minutes, checking often. Both methods will help keep the chicken juicy. You can freeze French onion chicken too! Wrap each piece tightly in plastic wrap. Then place them in a freezer-safe bag. This will help avoid freezer burn. You can store it in the freezer for up to three months. When ready to eat, thaw it overnight in the fridge. Reheat as mentioned before for best results. French onion chicken is a savory dish. It combines tender chicken breasts with sweet, caramelized onions.
