Ingredients

To prepare this delicious meal, you’ll need the following ingredients:

2 tablespoons unsalted butter
1 tablespoon olive oil
2 large yellow onions, thinly sliced
1 teaspoon sugar
1/2 teaspoon salt
3 garlic cloves, minced
1 1/2 cups orzo pasta
2 cups cooked shredded chicken
1/2 teaspoon dried thyme
1/4 teaspoon black pepper
2 cups low-sodium chicken broth
1 cup heavy cream (or half and half for a lighter option)
1 1/2 cups shredded mozzarella cheese
1/2 cup grated Parmesan cheese
Optional: 1/2 teaspoon Worcestershire sauce or balsamic glaze

Directions

Prepare Ingredients: Peel and thinly slice the 2 large yellow onions. For the best results, use a mandoline to ensure uniform slices. Mince the 3 garlic cloves and measure out the dried thyme. If needed, grate the mozzarella and Parmesan cheeses. Make sure you have your cooked shredded chicken ready.
Caramelize the Onions: In a large Dutch oven or heavy-bottomed pot, melt 2 tablespoons of unsalted butter and 1 tablespoon of olive oil over medium-low heat. Add the thinly sliced onions, along with 1/4 teaspoon salt and 1 teaspoon sugar. Toss to coat the onions, cover, and cook for 10-15 minutes, stirring occasionally to release moisture and soften. Uncover and continue cooking over medium-low heat, stirring about every 5-10 minutes, for 45-90 minutes until the onions are deeply golden brown and incredibly tender. If at any point the onions start to stick, add a tablespoon of water or broth to deglaze the bottom. Spoon out about 1/2 cup of the caramelized onions and set aside for topping, leaving the remaining onions in the pot.
Build the Flavor Base: To the pot with the remaining caramelized onions, add the minced garlic and 1/2 teaspoon dried thyme. Sauté for about a minute until fragrant. Pour in 1/2 cup of the low-sodium chicken broth to deglaze the pot, scraping up any browned bits at the bottom. If you’re using it, stir in the optional 1/2 teaspoon Worcestershire sauce or balsamic glaze. Allow the broth to simmer and reduce by half for about 2-3 minutes. Stir in 1 tablespoon of all-purpose flour and cook for 1 minute while stirring to eliminate the raw flavor of the flour.
Simmer the Orzo: Gradually add in the remaining 1.5 cups of low-sodium chicken broth while stirring continuously to prevent lumps. Bring the mixture to a gentle simmer, then stir in 1 cup of heavy cream (or half and half for a lighter option). Add in the 1 1/2 cups of orzo pasta and stir well to combine, making sure that the orzo is submerged in the mixture. Allow it to simmer, stirring frequently, for 8-10 minutes or until the orzo is about two-thirds cooked and has absorbed much of the liquid, reaching a very al dente texture while still remaining saucy. Season with 1/4 teaspoon of black pepper and adjust salt if necessary.
Assemble the Casserole: Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish. Stir the 2 cups of cooked shredded chicken into the pot with the partially cooked orzo mixture. Pour half of the chicken and orzo mixture into the prepared baking dish, spreading it evenly. Sprinkle half of the 1 1/2 cups of shredded mozzarella cheese over this layer. Spoon the remaining chicken and orzo mixture over the cheese and top with the rest of the mozzarella cheese, the 1/2 cup of grated Parmesan cheese, and the reserved 1/2 cup of caramelized onions.
Bake to Golden Perfection: Cover the baking dish tightly with aluminum foil and bake for 20 minutes. After this time, remove the foil and continue baking for another 15-20 minutes, or until the casserole is bubbling around the edges, the orzo is tender, and the cheese is beautifully golden and bubbly.
Rest and Serve: Take the casserole out of the oven and let it rest for 10-15 minutes before serving. Allowing it to rest lets the sauce thicken and the flavors meld beautifully. Consider garnishing with fresh chives or parsley if desired. Serve hot alongside a simple green salad or a loaf of crusty bread.

Tips to Make French Onion Chicken Orzo Casserole

Here are some quick tips to ensure your dish turns out perfectly every time:

Use Good Quality Cheese: Don’t skimp on the cheese; high-quality cheeses can make a world of difference in flavor and creaminess.
Adjust for Spice: If you like things spicy, consider adding a pinch of red pepper flakes when you’re sautéing the garlic.
Vegan Option: Swap out the chicken for cooked lentils or chickpeas and use vegan cheese for a plant-based version.

Variations or Substitutions

If you’re looking to switch things up or accommodate specific dietary preferences, here are a couple of great options:

Protein Swap: Instead of chicken, you could use cooked turkey, or for a vegetarian option, consider mushrooms or cooked lentils, which add hearty texture.
Herb Choices: Feel free to experiment with other herbs like rosemary or oregano for a different flavor profile.

FAQs

Q: Can I make this casserole ahead of time?

A: Absolutely! You can prepare it a day in advance and store it in the refrigerator. Just remember to let it come to room temperature before baking.

Q: Can I use chicken thighs instead of breasts?

A: Yes, chicken thighs will add even more richness to the dish due to their higher fat content.
