🥗🌟 Get ready to transform your holiday dishes with this homemade Keto Green Bean Casserole!
As a food blogger, crafting a spread that balances tradition and new flavors is always a delightful challenge, especially after transitioning to a low-carb lifestyle. Green bean casserole holds a special place in my heart, evoking memories from childhood feasts. Yet, traditional recipes featuring canned soup no longer fit my low-carb journey.
This year, trying out a low-carb version for Thanksgiving, I aimed to recreate the nostalgia of this beloved dish. The feedback from my husband's colleagues at their company Thanksgiving was overwhelmingly positive—the dish disappeared in a flash! Their response indicated I was on the right track.
I opted for canned green beans for convenience, but fresh or frozen work perfectly, with a suggested increase in cooking time for optimal tenderness.
As for the French's Fried Onions, their high carb content led me to create a homemade keto version. The process was a labor of love but resulted in an aromatic delight during baking. The house smelled incredible, and it received high praise from family members.
While the dish may not win awards for presentation, its creamy texture and fantastic taste truly shine through. And speaking of taste, the low-carb version holds a winning hand against the traditional recipe, offering fewer net carbs while maintaining richness and flavor.
If you're looking for a more carb-friendly alternative, this recipe is a wonderful addition to a low-carb/high-fat diet. Whether served during holiday meals or throughout the year, this keto rendition retains the essence of the classic dish while catering to dietary preferences.
In the end, it's the creamy delight and delicious flavors that matter most, making this homemade Keto Green Bean Casserole a warm and comforting addition to any festive spread!"

🔪Keto Green Bean Casserole Instructions
This is a basic breakdown of the steps involved in making Keto Green Bean Casserole. You will find the full directions in the recipe card at the bottom of the post.
Add the soup mixture to the mushrooms and stir to combine.
Pour half of the mushroom soup mixture into the bottom of a 2-quart baking dish and spread it out evenly.
Top with the drained green beans.
Then pour the remaining soup mixture on top, spreading it out with a rubber spatula.
Helpful Hint: 💡: Consider patting the canned green beans dry before layering them in the casserole. Removing excess moisture from the beans can prevent the dish from becoming overly watery and help maintain a desirable texture.
- Cheese Lover's Twist: Incorporate shredded cheese between the layers or on top of the casserole before baking. Cheddar, Parmesan, or a blend of your favorite cheeses can add extra richness and flavor.
- Crispy Bacon Addition: Fry or bake some bacon until crispy, crumble it, and sprinkle it over the casserole before serving. Bacon adds a savory crunch and an extra layer of taste.
- Fresh Herb Infusion: Enhance the flavors with fresh herbs. Adding a sprinkle of chopped parsley, thyme, or rosemary to the mushroom soup mixture or on top can elevate the dish's overall taste.
- Almond Flour Topping: Create a topping using a mixture of almond flour, butter, and a pinch of seasoning to replace or complement the fried onions. Sprinkle this over the casserole for a low-carb, crunchy alternative.
- Veggie Medley: Mix in additional low-carb vegetables such as bell peppers, broccoli, or cauliflower to the casserole for added variety and nutrients.
- Spice It Up: For a kick of heat, incorporate a dash of cayenne pepper or red pepper flakes into the mushroom soup mixture to give the casserole a spicy dimension.

Refrigerator: Once the Keto Green Bean Casserole has cooled completely, transfer any leftovers into an airtight container. Store it in the refrigerator for up to 3 to 4 days. Make sure to refrigerate within two hours of cooking to maintain freshness.
Freezer: This casserole can be frozen for longer-term storage. Place the completely cooled casserole in a freezer-safe container or resealable freezer bag, ensuring it's airtight to prevent freezer burn. It can last in the freezer for up to 2 to 3 months. When ready to use, thaw it in the refrigerator overnight before reheating.
Always label your containers with the date to keep track of freshness. Additionally, it's ideal to divide the casserole into smaller portions before freezing to make defrosting and reheating more manageable.
Experiment with different types of mushrooms to add variety to the casserole. Combining different varieties like shiitake or oyster mushrooms with cremini can create an interesting depth of flavors and textures in the dish.
