This oven baked 3-ingredient chicken a la king casserole is the kind of dependable comfort food that earns a permanent spot in a family recipe box. It takes a few simple pantry and freezer staples and turns them into a creamy, cozy casserole with that old-fashioned chicken a la king flavor so many of us grew up loving. It is especially handy on busy nights, for church suppers, or any time you need something warm and filling without a lot of fuss.

This casserole is lovely served over toast points, biscuits, rice, egg noodles, or mashed potatoes to catch every bit of the creamy sauce. For a full meal, I like to add a simple green salad, buttered green beans, or roasted carrots on the side, and for a casual gathering it fits right in with fruit salad, iced tea, and a simple dessert bar.

Ingredients

3 cups cooked chicken, chopped or shredded

2 cans condensed cream of chicken soup, undiluted
1 package frozen mixed vegetables with peas and pimentos, about 10 to 12 ounces

Directions

1. Preheat the oven to 350°F and lightly grease an oval casserole dish or 9x13-inch baking dish.

2. In a large mixing bowl, stir together the cooked chicken, condensed cream of chicken soup, and frozen mixed vegetables until evenly combined.

3. Spread the mixture evenly into the prepared baking dish.

4. Bake uncovered for 30 to 35 minutes, until hot and bubbly around the edges and the vegetables are tender.

5. Let the casserole rest for 5 to 10 minutes before serving, then spoon it over toast, rice, biscuits, noodles, or mashed potatoes if desired.

Variations & Tips

Make it extra hearty: Stir in a cup or two of cooked rice or egg noodles before baking if you want this to be a one-dish supper. You may need to add an extra spoonful or two of soup if the mixture seems too thick.

For picky eaters: If peas and pimentos are not a favorite at your table, use frozen mixed vegetables your family already enjoys, or even just peas by themselves for a gentler flavor and color.

Use what chicken you have: This is a wonderful use for leftover roasted chicken, poached chicken, or store-bought rotisserie chicken. If the chicken is well seasoned already, give the mixture a little taste before baking so it does not need anything extra.

Easy make-ahead meal: Assemble the casserole earlier in the day, cover, and refrigerate until dinnertime. When baking straight from the refrigerator, add about 5 to 10 extra minutes so it heats through completely.

Serving tip: Because the sauce is rich and creamy, this casserole really shines with something underneath it to soak it up. Toast, split biscuits, or buttered noodles make it feel especially comforting and stretch the meal nicely for hungry families.
