French onion chicken orzo casserole brings together the sweet depth of caramelized onions the coziness of baked pasta and the comfort of brothy chicken in one dish that is both impressive and fuss-free This is the kind of meal that tastes like you spent all day in the kitchen yet is weeknight-friendly My husband asks for this casserole after every chilly walk home and I love that it only gets better as leftovers

I first tried this casserole on a Sunday when we needed something hearty It quickly became my answer to both Sunday dinner and Monday lunch since everyone fights for leftovers

Gather Your Ingredients

• Unsalted butter: helps onions caramelize for a silky taste always use fresh for best flavor
• Olive oil: adds richness to the caramelization process choose a fruity one if you have it
• Large yellow onions: provide sweetness and depth slice them as thin as possible for best results
• Sugar: speeds up caramelization and brings out onion sweetness
• Salt: draws moisture from onions for that soft velvety texture
• Garlic cloves: add aromatic punch use fresh not pre-minced
• Orzo pasta: absorbs flavor and stays tender I look for bronze-cut brands for texture
• Cooked shredded chicken: uses up rotisserie chicken for convenience use moist dark and white meat mixed for more flavor
• Dried thyme: gives that subtle French herb note make sure your herbs are not expired
• Black pepper: brings gentle heat freshly ground is best
• Low-sodium chicken broth: keeps things juicy and lets you control the saltiness I like homemade or high-quality boxed
• Heavy cream: yields creaminess without being too rich use half and half for a lighter option
• Shredded mozzarella cheese: makes that coveted cheesy top buy whole milk blocks and shred for best melting
• Grated Parmesan cheese: adds depth and a nutty finish freshly grated tastes best

How to Make It

Caramelize the Onions:

In a large oven-safe skillet or Dutch oven melt butter and olive oil together over medium heat Add sliced onions sugar and salt Stir often and let them cook for twenty to twenty five minutes lowering the heat if the onions start to burn You want a rich deep golden brown result When the onions are almost ready stir in the garlic and cook for another minute or two The onions should be soft jammy and full of aroma

Add Orzo and Chicken:

Pour the orzo into the pan with the sunny onions Stir and let it toast for two minutes The orzo will pick up onion flavors and begin to smell nutty Add in the shredded chicken thyme and black pepper Mix so the chicken blends evenly with everything

Simmer with Broth and Cream:

Pour in the chicken broth and heavy cream Stir gently to combine Bring just to a simmer bubbling but not hard boiling Drop heat to low and cover Let it cook for eight to ten minutes stirring occasionally so the orzo cooks through and absorbs the sauce The mixture should be very creamy and the orzo soft

Stir in Cheese:

Remove the cover and add one cup of mozzarella and all of the Parmesan Stir well until all cheese melts making the casserole luscious and glossy

Bake the Casserole:

Heat the oven to three hundred seventy five degrees Fahrenheit Sprinkle the remaining mozzarella evenly on top Place the pan uncovered in the oven and bake for ten to fifteen minutes The casserole is ready when the top is melted deep golden and bubbling around the edges Let it sit for five minutes before serving so it sets and slices neatly

Caramelized onions are truly the hero here My entire family gathers in the kitchen as the onions cook nothing beats the smell and everyone helps taste until they are perfectly jammy Sometimes my daughter sneaks crispy bits from the pan once they cool

Flavor Boosters

In summer toss in a handful of spinach or sliced baby tomatoes for added freshness Winter calls for extra black pepper and a pinch more thyme for warmth During fall I sometimes top the casserole with a few sauteed mushrooms for earthiness

Serving Suggestions

Serve this casserole with a crisp green salad or simple roasted vegetables for a complete meal Its rustic flavors also go well with crusty bread Everything tastes as if it came from a French bistro yet is faster than ordering takeout

Creative Twists

Use turkey instead of chicken if you have holiday leftovers Substitute gruyere for mozzarella for even more French onion flavor Try whole wheat orzo for extra nutrition and a nutty bite

Letting the casserole rest makes the creamy texture and flavor shine We always hope for leftovers but there never seem to be any
