Step 5: Add the cooked mushroom mixture to the soup base and stir until everything is evenly blended.
Step 6: Place green beans into the slow cooker and pour the creamy mixture over them, stirring gently to coat.
Step 7: Sprinkle salt and black pepper on top, ensuring the seasoning is evenly distributed.
Step 8: Cover and cook on low for four to five hours or on high for two and a half hours until the beans are tender.
Step 9: Once cooked, sprinkle crispy fried onions and parmesan cheese evenly over the top.
Step 10: Cover again and let it sit on warm for about fifteen minutes before serving so the topping becomes crisp and golden.
Tips for Customizing the Recipe
The slow cooker green bean casserole can easily be adapted to fit your preferences or dietary choices. If you want a lighter option, use low-sodium soup or homemade cream sauce made with almond milk and whole wheat flour. For a vegan twist, swap the cream soup for a dairy-free mushroom blend and use vegan fried onions. Adding chopped bell peppers or crumbled turkey bacon can add flavor and texture variety. You can even sprinkle a bit of shredded cheddar or mozzarella just before adding the crispy onions for a more indulgent finish. Adjusting spices like paprika or nutmeg also gives the dish a unique twist while keeping it comforting and familiar.
