How To Make Trader Joe’s Green Bean Casserole
- Prep and Mix: Preheat the oven to 350°F. In a 1.5-quart casserole dish, stir together the cream of mushroom soup, milk, and soy sauce until smooth.
- Combine Ingredients: Gently fold in the green beans and 2/3 cup of the French fried onions. Season the mixture with salt and pepper to taste.
- First Bake: Bake the casserole for 25 minutes, or until the sauce is hot and bubbling around the edges.
- Top and Final Bake: Remove the casserole from the oven and stir the mixture. Sprinkle the remaining 2/3 cup of fried onions evenly over the top. Return to the oven and bake for another 5 minutes, until the onions on top are golden brown. Let the casserole rest for a few minutes before serving.

Recipe Tips
- What are the best green beans for this casserole? For the most classic, authentic texture, canned cut green beans, drained well, are the traditional choice. You can also use frozen cut green beans (thawed and drained) or fresh green beans (steamed or blanched until crisp-tender).
- How do you make this ahead of time? This is the perfect make-ahead holiday side. You can assemble the entire casserole (the soup, beans, and the first 2/3 cup of onions), cover it, and refrigerate for up to a day. When ready to bake, you may need to add 10-15 minutes to the initial bake time. Add the final onion topping just before the last 5 minutes of baking.
- Can I add cheese? Yes! A cheesy green bean casserole is a delicious variation. Stir in 1 cup of shredded sharp cheddar cheese along with the soup and milk mixture.
- How do I prevent a watery casserole? The most important step is to make sure your green beans are well-drained. If you are using canned beans, drain them thoroughly. If using frozen, let them thaw and pat them dry to remove excess moisture.
What To Serve With Green Bean Casserole
This is the quintessential American holiday side dish. It is a must-have on the table for any Thanksgiving or Christmas feast, served alongside:
- Roast Turkey and Gravy
- A glazed Holiday Ham
- Creamy Mashed Potatoes
- Soft Dinner Rolls
How To Store Green Bean Casserole
- Refrigerate: Cover leftovers tightly with foil or transfer to an airtight container. It will keep well in the refrigerator for up to 4 days. Note that the onion topping will soften.
- Reheat: For the best results, reheat the casserole in a 350°F oven for 15-20 minutes, until warmed through. This will help re-crisp the topping slightly.
