Step-by-Step Preparation of French Onion Chicken Orzo Casserole
Creating a French Onion Chicken Orzo Casserole brings the warmth of a home-cooked meal right to your table. This dish harmonizes sweet, caramelized onions with tender chicken and creamy orzo for a delightfully comforting experience. Let’s dive into the step-by-step preparation of this delicious casserole.
Caramelize the Onions
Start by melting 2 tablespoons of unsalted butter and 1 tablespoon of olive oil in a large oven-safe skillet or Dutch oven over medium heat. Once the fat is sizzling, add 2 large yellow onions, thinly sliced, along with 1 teaspoon of sugar and ½ teaspoon of salt. This is where the magic begins! Cook them for 20–25 minutes, stirring occasionally, until they reach that beautiful, deep golden color we're looking for.
Just as the onions are about to become perfect, toss in 3 minced garlic cloves and let them cook for an additional 1–2 minutes. The aroma will have your mouth watering! For more tips on caramelizing onions, check out this resource from Serious Eats.
Add Orzo and Chicken
With your onions nicely caramelized, it’s time to introduce the other hearty ingredients. Stir in 1 ½ cups of orzo pasta and toast it lightly for about 2 minutes. The toasting adds a lovely flavor! Once the orzo is fragrant, add in 2 cups of shredded cooked chicken (rotisserie chicken works beautifully here), ½ teaspoon dried thyme, ¼ teaspoon black pepper, and if you’re feeling adventurous, a dash of Worcestershire sauce for some depth.
Pour in Chicken Broth and Cream
Now, let’s create that creamy sauce! Pour in 2 cups of low-sodium chicken broth and 1 cup of heavy cream (or half and half if you prefer a lighter option). Bring the mixture to a gentle simmer, then reduce the heat to low, cover, and allow it to cook for about 8–10 minutes. This will give the orzo time to absorb some liquid and cook through. Remember to stir occasionally, observing the transformation unfold!
Incorporate the Cheeses
Next up is the cheese—because what dish isn't better with cheese? Stir in 1 cup of shredded mozzarella and ½ cup of grated Parmesan cheese. Mix until everything melts into a creamy, dreamy sauce. This is the heart of your French Onion Chicken Orzo Casserole.
Bake the Casserole to Perfection
To finish things off, preheat your oven to 375°F (190°C) and sprinkle the remaining ½ cup of mozzarella on top of the casserole. Pop it into the oven uncovered for about 10–15 minutes until the top is bubbly and golden brown.
Don’t rush this part—let it rest for 5–10 minutes before serving to allow the flavors to meld beautifully. Garnish with fresh thyme or parsley for an extra touch. A delicious meal like this is sure to impress your friends or family, so invite them over for dinner!
