Ingredients You’ll Need
- Frozen Green Beans (24 oz): These provide the vibrant color and crisp-tender texture. You can use fresh beans, but frozen offers a year-round convenience. Just make sure they’re thawed before using.
- Cream of Mushroom Soup (2 cans): This creamy base adds richness and flavor, binding the dish together. If preferred, you can substitute with cream of celery soup for a different twist.
- Milk (½ cup): This helps to thin the soup slightly while enhancing the creaminess. Dairy-free milk alternatives work here, too.
- Salt (½ tsp): Essential for enhancing all the flavors. You can adjust this based on your dietary preferences.
- Pepper (½ tsp): Adds a little spice and depth to the flavor. Freshly ground black pepper is always my recommendation for the best taste.
- French Fried Onions (6 oz can): The crowning glory of this dish, they provide a satisfying crunch. You can also use homemade crispy onions if you’re feeling adventurous!
How to Make Easy Green Bean Casserole
Preheat and Prepare: Start by preheating your oven to 350°F. While it heats, grab a 9×13 inch baking dish and give it a light coat of cooking spray or olive oil. This prevents sticking and ensures easy serving later. The anticipation of that bubbling goodness makes this step especially exciting!
Mix Together: In a large mixing bowl, combine the thawed green beans, cream of mushroom soup, milk, salt, and pepper. Stir gently until everything is well coated. The creamy concoction should feel rich and luscious. You’ll hardly be able to resist sneaking a taste at this point, but hold off- the best is yet to come!
Layer the Mixture: Pour the green bean mixture into your prepared baking dish, spreading it out evenly with a spatula. You’ll want the surface to be smooth and inviting, making sure every bean is nestled nicely in that delicious sauce. Each layer should look like a promise of warmth and comfort!
Top it Off: Now, it’s time to sprinkle the French fried onions generously over the top. They’re the golden crown of this dish, and their crunch is what makes each bite special. Feel free to add extra if you love a little more crunch; it only amplifies the deliciousness!
Bake Until Golden: Slide the dish into the preheated oven and let it bake for 30-35 minutes, or until the edges are bubbling and the onions are golden brown. As it bakes, the aroma will fill your kitchen, making it hard to wait for the final reveal. Trust me; it’s worth every minute of the wait!
Serve and Enjoy: Once out of the oven, allow it to cool slightly before diving in. This dish is best served warm, and leftovers are a delightful treat. Whether as a side or on its own, every bite of this **Easy Green Bean Casserole** is sure to become a new favorite!

Storing & Reheating
Leftovers can be stored at room temperature for up to 2 hours. After that, transfer it to an airtight container and refrigerate for up to 4 days. For longer storage, you can freeze it, placing portions in a freezer-safe container for up to 3 months. When reheating, place the casserole in the oven at 350°F for about 15-20 minutes until warmed through; you might want to freshen up that crunchy topping by adding a sprinkle of fresh fried onions. Keep in mind that the texture may soften a bit once reheated, but it will still be as tasty!
Chef’s Helpful Tips
- Avoid sogginess by not overcooking the green beans before baking.
- Use room temperature milk to help it blend effortlessly without clumping.
- Timing is key; if baking alongside another main dish, keep an eye on both to ensure they finish around the same time.
- If you prefer extra crunch, add the fried onions only during the last 10 minutes of baking.
- Making this ahead? Assemble the casserole but wait to bake it until just before serving. This keeps the texture perfect!
