This little oven baked 4-ingredient cheesy Reuben chicken casserole is the kind of dish that shows up at card tables and church basements all over the Midwest. My best friend first brought it to our Thursday bridge game, and we all stopped shuffling when we smelled it. It has every bit of that Reuben sandwich flavor—tangy sauerkraut, creamy Thousand Island, and melty Swiss—without a pile of ingredients or fussy steps. It’s a practical, no-nonsense bake that tastes like you fussed all afternoon, even though it comes together in minutes.
I like to spoon this cheesy Reuben chicken over buttered egg noodles or alongside boiled or mashed potatoes to soak up the extra sauce. A simple green salad with a sharp vinaigrette or some steamed green beans balances the richness nicely. Rye bread or toast on the side really drives home that classic Reuben flavor, and a few dill pickles on the plate never hurt. It’s hearty enough for company but easy enough for a quiet weeknight supper.
Oven Baked 4-Ingredient Cheesy Reuben Chicken CasseroleServings: 4
Ingredients
4 boneless, skinless chicken breasts (about 2 pounds total)
2 cups drained sauerkraut, lightly squeezed dry
1 cup Thousand Island dressing
8 slices Swiss cheese (enough to cover the top)
Directions
Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch glass baking dish.
Arrange the chicken breasts in a single layer in the prepared baking dish. If they are very thick, you can pound them gently to an even thickness so they cook more evenly.
Spread the sauerkraut evenly over the chicken, making sure each piece is well covered. Lightly press it down so it stays in place.
Drizzle the Thousand Island dressing evenly over the sauerkraut and chicken, using the back of a spoon to spread it so most of the surface is coated.
Lay the Swiss cheese slices over the top, overlapping slightly as needed so the chicken and sauerkraut are mostly covered in a blanket of cheese.
Cover the baking dish loosely with foil and bake for 20 minutes.
Remove the foil and continue baking for another 15–20 minutes, or until the chicken is cooked through (internal temperature reaches 165°F/74°C) and the cheese is fully melted and bubbling around the edges.
Let the casserole rest for 5–10 minutes so the juices settle, then spoon the chicken breasts out with plenty of sauerkraut, sauce, and melted Swiss on top. Serve warm.
Variations & Tips
If your family likes a little extra sauce, add another 1/4 to 1/2 cup of Thousand Island dressing before baking. For a stronger Reuben flavor, use a darker, more pungent sauerkraut and don’t rinse it—just squeeze it lightly so the casserole doesn’t get watery. You can also cut the chicken into large chunks and scatter them in the dish if you prefer a scoopable casserole instead of whole breasts. If your chicken breasts are very large, slice them horizontally into cutlets so they cook more quickly and evenly. For a slightly browned top, run the casserole under the broiler for 1–2 minutes at the end of baking, watching closely so the cheese doesn’t burn. Leftovers reheat well; cover the dish with foil and warm in a low oven until hot, or reheat individual portions gently in the microwave so the chicken stays tender.
