Chicken and Stuffing Casserole from Scratch
This chicken and stuffing casserole puts tender chicken and vegetables under a golden bread topping, with a simple homemade sauce holding everything together. The bread stays soft underneath and crisp around the edges. It is a good way to turn cooked chicken into a generous family dinner without opening a can of condensed soup.
Think of the filling as a close cousin of chicken pot pie, with herb-scented bread in place of pastry. You make the sauce in a saucepan, moisten the bread separately and bring the two together in a baking dish. Keeping those steps separate gives you control over both textures.
Start with bread that can absorb broth
Use six loosely filled cups of dry bread cubes, about eight ounces. A plain white country loaf or ordinary sturdy sandwich bread works well. Cut it into three-quarter-inch pieces. If the bread is fresh, spread it on a sheet pan and dry it at 300°F for fifteen to twenty minutes, stirring once. It should feel dry on the outside without becoming deeply toasted.
Very airy bread and dense sourdough do not absorb exactly the same amount of liquid. Add the broth gradually and stop when the cubes are moist but still distinct. You should be able to press one gently without releasing a puddle. This is a topping, not a smooth bread paste.
The flavour is simpler than my bread stuffing with bacon. Sage, thyme, celery and onion provide the savoury base here. There is no bacon in this version, which keeps the chicken flavour clear and avoids adding another salty ingredient.
A creamy filling that is not soupy
The filling uses three cups of cooked chicken, two cups of chicken broth and one cup of milk. Butter and flour thicken those liquids into a sauce that can support the bread. The sauce should coat a spoon before it goes into the dish. It will loosen a little around the vegetables as the casserole bakes.
Cut or shred the chicken into bite-sized pieces. Long strands are harder to serve neatly. Remove skin, bones and any cartilage. Plain roast chicken is ideal; leftovers from maple roast chicken also work if you leave most of the sweet skin and glaze out of the filling.
Cooked turkey is equally useful. If you have made roast turkey with bread stuffing, keep the leftover meat separate from its original stuffing and use fresh bread topping for this casserole. The storage time of the meat still counts when you turn it into another dish.
Assemble the casserole
Soften the vegetables for the filling
Heat the oven to 375°F and butter a nine-by-thirteen-inch baking dish. Melt three tablespoons of butter in a large saucepan over medium heat. Add one diced onion, two diced carrots and one diced celery stalk. Cook eight to ten minutes, stirring, until the vegetables begin to soften. Add two minced garlic cloves and stir for thirty seconds.
Sprinkle in a quarter cup of flour and stir for one minute. Gradually whisk in two cups of low-sodium chicken broth, followed by one cup of milk. Simmer gently for three to five minutes, stirring along the bottom, until the sauce coats a spoon. Add half a teaspoon of dried thyme and a quarter teaspoon of pepper.
Add chicken and peas
Fold in the chicken and one cup of frozen peas. Taste the sauce and add salt only as needed. Transfer to the prepared dish and spread evenly. The vegetables should be coated generously, with sauce visible between the pieces, rather than sitting in a clear broth.
If the sauce is very thick before the chicken goes in, add a tablespoon or two of broth. If it is thin, simmer it a little longer first. It is easier to correct the sauce in the saucepan than to compensate by adding extra bread after assembly.
Make the bread topping and bake
In a skillet, melt the remaining three tablespoons of butter. Add half a diced onion and one diced celery stalk. Cook five to seven minutes until softened. Stir in one teaspoon of dried rubbed sage and half a teaspoon of dried thyme. Toss with the bread cubes, then add three-quarters of a cup of broth. Rest two minutes and add up to another quarter cup if the bread still feels dry in the centre.
Scatter the moistened bread loosely over the filling. Do not press it into a dense layer. Bake uncovered for thirty to forty minutes, until the filling bubbles and the centre reaches 165°F. If the top colours early, cover loosely with foil. Rest ten minutes before serving so the sauce settles around the chicken.
Chef tips
I recommend a shallow dish of the stated size so each portion gets some crisp bread. A deep, narrow dish takes longer to heat through and gives you less crisp topping per serving. Place a sheet pan on the rack underneath if your dish is particularly full, but do not crowd the casserole with other pans that block hot air.
The bread should look uneven on top. Those little ridges brown more readily than a compressed flat surface. If you like a soft topping, cover for the first twenty minutes and uncover for the rest. Always check the centre temperature rather than judging readiness from the browned bread alone.
For a different one-dish chicken dinner, try creamy chicken pasta or garlic butter chicken pasta. This casserole takes longer in the oven but needs very little attention once assembled.
Substitutions
If you have cooked turkey to use up, I’d substitute it for the chicken measure for measure. Small diced cooked green beans can replace the peas. Use fresh herbs if you have them, allowing about one tablespoon of chopped fresh sage for the teaspoon of dried sage and one tablespoon of fresh thyme for the total teaspoon of dried thyme.
Avoid sweet brioche unless you want a noticeably sweeter topping. A strongly flavoured stuffing mix also changes the salt and herb balance; the quantities here are for plain bread. For a meal built around individually filled chicken breasts instead, see stuffing-stuffed chicken breast.
Frequently asked questions
Can I assemble it ahead?
Make the filling a day ahead, cool promptly and refrigerate. Keep the bread dry and prepare its broth mixture shortly before baking. Add the topping just before the dish goes into the oven. A cold filling needs extra baking time, often ten to fifteen minutes; check for 165°F in the centre.
Can I freeze it?
Freeze cooled portions for up to two months. Thaw in the refrigerator, then reheat covered at 350°F until the centre reaches 165°F. Uncover near the end to refresh the bread. The topping will be softer than it was on the first day, but the flavour holds well.
How long do leftovers keep?
Refrigerate promptly in shallow containers and use within three days, or sooner if the chicken was already stored before assembly. Reheating does not reset its storage clock. A splash of broth helps keep individual portions moist when reheated.
What to serve alongside
A romaine and endive salad provides a crisp contrast. Creamy coleslaw is another option if you prefer a cold side. Keep portions of extra starch modest because the bread is already part of the main dish. For dessert, a small serving of apple crisp fits the same relaxed family-table mood.
