Chicken Rice Casserole

From-scratch cream sauce, not canned soup

Chicken-rice casserole is a mid-century American standard that has been made in home kitchens for decades for good reason. Cooked chicken and rice in a homemade cream sauce with mushrooms, green bell pepper, pimientos, and slivered almonds, baked until bubbly. The technique is simple enough that it reads as assembly, but the from-scratch cream sauce makes a real difference compared to the canned-soup version many people grew up with.

This is a recipe for using leftover or rotisserie chicken. The chicken goes in already cooked; the casserole is about the sauce and the bake, not about cooking the protein. Forty-five minutes of actual cooking, twenty minutes of prep, serves six with modest effort.

The cream sauce

A quarter cup of butter melted in a two-quart saucepan over medium heat. Stir in a third of a cup of flour, three-quarters of a teaspoon of salt, and an eighth of a teaspoon of pepper, then cook, stirring constantly, until the mixture bubbles. This is a roux: fat and flour cooked together until the raw flour taste cooks out, which takes about one to two minutes of steady stirring. Remove from the heat before adding the liquid.

Stir in one and a half cups of milk and a cup of chicken broth, return to heat, and bring to a boil, stirring constantly. The constant stirring is what keeps the sauce smooth rather than lumpy; starch granules need to stay dispersed as they hydrate and thicken. Boil and stir for one minute once the sauce reaches a full boil. At this point it should be smooth, thick, and glossy.

Add everything else directly to the sauce: the two cups of cut-up cooked chicken, the one and a half cups of cooked white rice, the sliced mushrooms, chopped green bell pepper, slivered almonds, and pimientos. Stir to combine. The sauce is the binder that holds the whole casserole together as it bakes.

The almonds and their options

The slivered almonds can go two ways. Mixed into the casserole before baking, they soften during the forty-five-minute bake and provide a mild crunch in each forkful. Held back and scattered over the top ten minutes before the casserole is done, they toast in the oven and become genuinely crunchy, adding a different textural element to the top of each serving. Both are good; the second approach produces a more dramatic contrast and is worth trying if you haven’t.

Assembly and the bake

Pour the filled sauce into an ungreased two-quart casserole dish or an eight-by-eight baking pan. Bake uncovered at 350 degrees for forty to forty-five minutes until the casserole is bubbling around the edges and heated through. Casseroles need that bubbly stage because it tells you the center has reached temperature rather than just the edges. A casserole that’s hot at the edges and cold in the middle is undercooked.

Garnish with fresh parsley if you have it. The green against the pale cream casserole adds a visual note that’s minor but worth doing if you’re serving guests.

The pimientos

Two tablespoons of chopped pimientos sounds like an afterthought and is not. Pimientos are mild, sweet red peppers preserved in jars, available in the olive and condiment aisle of most grocery stores. They add a pop of red color to the casserole and a slight sweet note that the green bell pepper doesn’t provide. They’re not essential, but they’re the ingredient that makes the casserole look like something rather than a beige dish.

Variations the recipe suggests

The recipe itself notes three variations that work in the same method. Canned drained tuna in place of chicken gives you a tuna-rice casserole that uses pantry ingredients with no need for leftover chicken. Cooked turkey in place of chicken and wild rice in place of white rice produces a turkey-wild rice version with a deeper, earthier flavor, well suited to post-Thanksgiving leftovers. Canned mushroom pieces, drained, work in place of fresh mushrooms. All of these keep the roux-based cream sauce and the bake method identical.

Casseroles and their place in the kitchen

There’s a category of American cooking that gets dismissed as unfashionable that I find genuinely interesting, not for nostalgia but because these recipes are often more technically considered than they appear. A roux-based cream sauce from scratch, rather than a can of condensed soup, is real cooking. The technique of cooking the roux until it bubbles before adding liquid is classical French method applied to a midwestern casserole. The result is a sauce with body and flavor that doesn’t have the metallic edge of canned cream of chicken soup.

This casserole makes good use of cooked chicken that might otherwise be turned into a sandwich or discarded. It serves six from one dish and reheats well the next day with a splash of broth to loosen the sauce. Calories per serving: 300, total fat 15g, protein 19g, carbohydrates 22g.

Make it ahead

Prepare the sauce and combine with all the fillings, pour into the casserole dish, cover, and refrigerate for up to 24 hours before baking. Add 10 minutes to the bake time if starting from cold. The casserole can also be frozen before baking; thaw completely overnight in the refrigerator before putting it in the oven.

Frequently Asked Questions

Expand All:

Why make the sauce from scratch instead of using canned cream of chicken soup?

A from-scratch roux-based sauce has a cleaner, less metallic flavor and you control the seasoning. It takes about 5 minutes more than opening a can and makes a meaningful difference in the finished dish.

Can I use canned mushrooms instead of fresh?

Yes. One 4-ounce can of mushroom stems and pieces, drained, substitutes directly for the fresh mushrooms.

What is the best way to handle the almonds for a crunchy topping?

Hold the almonds back from the main mixture. Scatter them over the top of the casserole about 10 minutes before it finishes baking so they toast and stay crunchy rather than softening inside the sauce.

Can I substitute tuna or turkey for the chicken?

Yes. One 12.5-oz can of drained tuna works in place of chicken. Cooked turkey works as a direct substitution. Wild rice can replace white rice for a heartier, earthier result.
