Before you start
Before starting, make sure the slow cooker is clean and dry. If using fresh green beans, trim the stem ends and discard any that are wilted. If your turkey cutlets are very thick, slice them horizontally into 1-inch pieces.
Measure out the sour cream and shred the Swiss cheese if you bought it in a block. Have the condensed soup can open and ready. No need to preheat or brown anything — this recipe is truly dump-and-go.
Ingredients at a glance (5)
- 1 1/2 lb boneless skinless turkey breast cutlets
- 1 lb fresh French green beans, trimmed
- 1 can (10.5 oz) condensed cream of onion soup
- 1/2 cup sour cream
- 1 cup shredded aged Swiss cheese
Instructions
Layer and Top
- Layer the Turkey and Green BeansPlace the turkey breast cutlets in the bottom of a 7-quart slow cooker in a single layer. Scatter the trimmed green beans over and around the turkey, tucking them between the pieces so they are mostly covered by the liquid as it cooks.Look for The turkey and green beans should fill the bottom of the slow cooker evenly.Safe temperature 165°F (74°C) internal temperature (poultry)Tip If the cutlets are very thick, slice them horizontally into 1-inch pieces so they cook evenly.
- Add the Cream of Onion SoupDollop the condensed cream of onion soup over the turkey and green beans. Spread it gently with a spoon or spatula, but do not stir everything together — the soup will melt and create the sauce as it cooks.Look for The soup sits in thick dollops on top of the turkey and beans.Tip No need to add water or broth; the turkey and beans release enough liquid.
- Top with Sour Cream and Swiss CheeseSpoon the sour cream over the soup, then sprinkle the shredded Swiss cheese evenly across the top. Do not stir. Cover the slow cooker with the lid.Look for The top is covered with sour cream and a blanket of shredded cheese.Tip Use aged Swiss for a more pronounced flavor; younger Swiss is milder.
After this phase, the slow cooker contains raw turkey breast cutlets, green beans, and dollops of soup, sour cream, and shredded cheese. The top looks like a patchwork of white and golden-brown. The cheese is still in shreds, and the sour cream is in distinct spoonfuls. Everything is ready to cook.
Slow Cook and Shred
- Cook on Low Until Turkey Is TenderSet the slow cooker to LOW and cook for 4 to 5 hours, or until the turkey breast reaches an internal temperature of 165°F (74°C) and shreds easily with a fork. The sauce will be bubbling gently around the edges.Look for The sauce is bubbly, the cheese is melted, and the turkey is fork-tender.Safe temperature 165°F (74°C) internal temperature (poultry)Tip Check the temperature at 4 hours; cooking times can vary with the size of the cutlets.
- Shred the Turkey in the Slow CookerUsing two forks, shred the turkey breasts directly in the slow cooker. Stir the shredded turkey into the sauce and green beans so everything is coated. Let it sit for 5 minutes to absorb the sauce.Look for The turkey shreds easily and the sauce is creamy and thick.Tip Do not over-shred; large chunks keep the dish hearty.
The slow cooker is bubbling at the edges, and the sauce has turned a rich, creamy golden color. The cheese is fully melted and blended into the sauce.
The turkey is fork-tender and shreds easily, and the green beans are tender but not mushy. The aroma is deeply savory with notes of onion and Swiss cheese.
Serve
- Serve Over Mashed PotatoesSpoon the creamy turkey and green bean mixture over warm mashed potatoes on individual plates. The sauce will pool around the potatoes, soaking into them as you eat.Look for Each plate has a generous scoop of the turkey mixture over a bed of mashed potatoes.Tip For extra richness, drizzle a little of the sauce over the potatoes before adding the turkey.
The turkey and green beans are coated in the glossy sauce, and the mixture is steaming. When spooned over mashed potatoes, the sauce pools around the potatoes. Each plate holds a generous serving, and the dish is ready to eat immediately.
Common mistakes
One common mistake is stirring the ingredients before cooking. This can cause the dairy to curdle or the cheese to seize. Another is overcooking, which makes the turkey dry and stringy.
Check the temperature at the 4-hour mark. Also, do not add extra liquid — the turkey and beans release enough moisture. Finally, avoid using low-fat sour cream, as it can separate and make the sauce grainy.
How to tell it’s done
The dish is done when the turkey breast reaches an internal temperature of 165°F (74°C) on an instant-read thermometer. The turkey should shred easily with a fork, and the green beans should be tender but still have a slight bite.
The sauce will be bubbly, thick, and creamy, with the cheese fully melted. If the sauce looks too thin, let it cook uncovered for an additional 15–20 minutes to reduce.
