Ingredients You’ll Need
Gathering your ingredients is the first step to culinary success. Most of these items are pantry staples, making this a convenient dish to whip up whenever the craving strikes.
- For the Chicken and Rice Base:
- 2 tablespoons olive oil
- 1 ½ pounds boneless, skinless chicken breasts or thighs, cut into 1-inch cubes
- 1 large yellow onion, thinly sliced (about 2 cups)
- 2 cloves garlic, minced
- 1 teaspoon dried thyme
- ½ teaspoon dried rosemary, crushed
- Salt and freshly ground black pepper to taste
- 1 ½ cups uncooked long-grain white rice, rinsed
- 4 cups vegetable broth (ensure it’s low sodium if preferred)
- 1 cup heavy cream
- 1 cup shredded Gruyere cheese (or a blend of mozzarella and Swiss cheese for a similar melty texture)
- ½ cup grated Parmesan cheese
- For the Crispy Topping:
- 2 cups crispy fried onions (store-bought or homemade)
- Fresh parsley or chives, chopped, for garnish (optional)
Step-by-Step Instructions
Follow these simple steps to create your own delicious Rustic French Onion Chicken & Casserole.
Step 1: Prepare the Chicken and Onions
- Heat the olive oil in a large oven-safe Dutch oven or a large skillet over medium-high heat.
- Add the cubed chicken and season with salt and pepper. Cook for 5-7 minutes, stirring occasionally, until browned on all sides. The chicken doesn’t need to be cooked through at this stage, as it will finish cooking in the oven. Remove the chicken from the skillet and set aside.
- Add the thinly sliced yellow onion to the same skillet. Reduce the heat to medium-low and cook, stirring frequently, for 15-20 minutes, or until the onions are deeply caramelized and tender. This step is crucial for developing the rich, sweet flavor of the casserole, so don’t rush it! If the onions start to stick, add a tablespoon or two of water or broth to deglaze the pan.
- Once the onions are beautifully caramelized, add the minced garlic, dried thyme, and crushed rosemary to the skillet. Cook for another minute until fragrant.
Step 2: Assemble the Casserole Base
- Add the rinsed long-grain white rice to the skillet with the caramelized onions and garlic. Stir to coat the rice evenly with the aromatic mixture.
- Pour in the vegetable broth and heavy cream. Bring the mixture to a gentle simmer, stirring constantly to prevent the rice from sticking.
- Return the browned chicken to the skillet. Stir everything together well.
- Remove the skillet from the heat. Stir in the shredded Gruyere cheese and grated Parmesan cheese until well combined and the cheese begins to melt into the sauce. Taste and adjust seasoning with additional salt and pepper if needed.
Step 3: Bake the Casserole
- If your skillet is oven-safe, simply transfer it to the oven. If not, transfer the entire mixture to a 9×13 inch baking dish.
- Cover the casserole dish tightly with aluminum foil.
- Bake in a preheated oven at 375°F (190°C) for 25-30 minutes, or until the rice is tender and has absorbed most of the liquid.
- Remove the foil. Sprinkle the crispy fried onions evenly over the top of the casserole.
- Return the casserole to the oven, uncovered, and bake for another 5-10 minutes, or until the crispy fried onions are golden brown and warmed through. Keep a close eye on them to prevent burning.
Step 4: Garnish and Serve
- Once baked, remove the casserole from the oven and let it rest for 5-10 minutes before serving. This allows the flavors to meld and the casserole to set slightly.
- Garnish with fresh chopped parsley or chives, if desired, for a pop of color and freshness.
- Serve hot and enjoy!
Tips for Success
- Caramelization is Key: Don’t skimp on the time for caramelizing the onions. This step truly builds the foundation of flavor for the entire dish. Low and slow is the way to go.
- Rinsing the Rice: Rinsing the rice helps remove excess starch, preventing the casserole from becoming gummy.
- Evenly Cut Chicken: Cutting the chicken into uniform pieces ensures even cooking.
- Cheese Choices: While Gruyere offers that authentic French onion soup flavor, a combination of mozzarella and Swiss cheese can be a great substitute for a lovely melt.
- Homemade Crispy Onions: If you’re feeling ambitious, you can make your own crispy fried onions. Thinly slice onions, toss with a bit of flour, and fry in hot oil until golden and crisp. However, store-bought works perfectly and saves time!
- Adjusting Consistency: If the casserole seems too dry after baking, you can stir in a splash more broth or cream. If it’s too wet, continue baking uncovered for a few more minutes.
Serving Suggestions
This Rustic French Onion Chicken & Casserole is a complete meal on its own, but it pairs wonderfully with a few simple sides:
- A Simple Green Salad: A crisp salad with a light vinaigrette provides a refreshing contrast to the rich casserole.
- Steamed Green Beans or Asparagus: These vegetables add a touch of freshness and color to the plate.
- Crusty Bread: While the casserole has rice, a piece of crusty bread is always welcome for soaking up any extra creamy sauce.
Storing and Reheating Leftovers
Leftovers of this casserole are just as delightful!
- Storage: Store any leftover casserole in an airtight container in the refrigerator for up to 3-4 days. The crispy onions may soften slightly upon storage.
- Reheating: To reheat, spoon individual portions into a microwave-safe dish and heat until warmed through. For larger portions or to crisp up the onions again, reheat in an oven-safe dish at 300°F (150°C) for 15-20 minutes, or until hot. You might want to add a fresh sprinkle of crispy fried onions during the last few minutes of oven reheating for extra crunch.
