Ingredients List for Crockpot Green Bean Casserole

To make this crockpot green bean casserole, you'll need the following basic ingredients. These items are easy to find and can be sourced from any grocery store:

• Fresh or Frozen Green Beans: 2 lbs. Fresh green beans give a crispier texture, but frozen green beans work just as well if you're short on prep time.
• Cream of Mushroom Soup: 2 cans (10.5 oz each). This is the creamy base of the casserole. You can also use cream of chicken or celery soup if you prefer.
• Milk: ¾ cup to thin the soup a bit and create a creamy sauce.
• Soy Sauce: 2 tablespoons for added depth and savory umami flavor.
• Black Pepper: ½ teaspoon or to taste for seasoning.
• Garlic Powder: ½ teaspoon to add a bit of warmth and flavor.
• Fried Onions: 1 can (6 oz), divided. These are essential for that classic crispy topping. You'll stir some into the casserole and save the rest for the topping.
• Optional Add-Ins: Shredded cheese (like cheddar or mozzarella), bacon bits, or sautéed mushrooms.

Step-by-Step Cooking Instructions

This Crockpot Green Bean Casserole is incredibly simple to prepare. Follow these instructions for a perfectly creamy and flavorful dish.

1. Prep the Green Beans: If you are using fresh green beans, wash them and trim off the ends. You can cut them into smaller pieces if desired. If you're using frozen green beans, no need to thaw them—just add them straight to the crockpot.
2. Mix the Sauce: In a mixing bowl, whisk together the cream of mushroom soup, milk, soy sauce, garlic powder, and black pepper until smooth. This creates the creamy, flavorful base of the casserole.
3. Assemble the Casserole in the Crockpot: Add the green beans to the crockpot, and then pour the creamy sauce over them. Stir to coat the beans evenly. Add half of the crispy fried onions into the mixture and stir again to combine.
4. Cook on Low: Cover the crockpot and cook on Low for 4-5 hours or on High for 2-3 hours. The slow cooking process will allow the flavors to meld together while keeping the green beans tender but not mushy.
5. Add the Topping: About 15-20 minutes before serving, sprinkle the remaining crispy fried onions over the top of the casserole. Cover again and let them heat through for the final 15 minutes. This will give the onions time to crisp up without losing their texture.
6. Serve and Enjoy: Once the casserole is cooked and topped with crispy onions, it’s ready to serve. Give it a quick stir to redistribute the sauce if necessary, or simply scoop it out and enjoy!

Common Mistakes to Avoid

1. Not Using Enough Liquid: Make sure you add enough milk to thin the soup, or the casserole may turn out too thick. If you prefer a creamier consistency, add an extra splash of milk or even some heavy cream.
2. Overcooking the Green Beans: While the crockpot makes cooking easy, be careful not to overcook the green beans. Cooking them on Low for too long can make them mushy.
3. Adding Fried Onions Too Early: If you add the fried onions at the beginning, they may lose their crunch by the time the casserole is done cooking. Always reserve some onions for the final topping added just before serving.
4. Skipping Seasoning: Don’t forget to season the dish! The cream of mushroom soup and fried onions are savory, but they won’t add all the flavor you need. Soy sauce, garlic powder, and black pepper are essential for depth.
