Why Are Green Beans Used in Many Keto Recipes?

Green beans are one of those ingredients that just check all the boxes for a keto lifestyle. They’re low in net carbs, high in fiber, and surprisingly versatile. Their texture holds up well in casseroles, stir-fries, and soups, and they pair beautifully with savory and creamy sauces.

They also bring a subtle earthiness and crunch that makes a dish feel more substantial—without the starchiness of potatoes or other root veggies.

Plus, they’re easy to find year-round and are often already in your pantry or freezer. All of this makes them a natural favorite for keto-friendly comfort food.

What Is Keto Green Bean Hamburger Casserole?

At its heart, this casserole is a delicious blend of rich, seasoned ground beef and crisp green beans, all bound together with a luxuriously creamy sauce and topped with melty cheese. Think of it like a keto twist on classic green bean casserole, but with way more protein and flavor—and none of the carbs you’re trying to avoid.

The “hamburger” component is made with plant-based ground beef, which browns up just like traditional beef and adds that savory depth that makes this dish irresistible.

Cream cheese, coconut milk, and shredded cheeses bring the whole dish together into a perfectly baked casserole that’s gooey, golden, and dinner-table ready.

Ingredients for the Best Results

This recipe is all about using the right combination of ingredients to get that rich flavor and creamy texture while staying low in carbs. I start with already-cooked green beans—either steamed or blanched—because it cuts down on prep time and helps them stay tender without going mushy in the oven.

Sautéed onions and garlic bring aromatic depth, while a splash of soy sauce and paprika elevates the umami and gives it a cozy, smoky finish. The ground beef component cooks up quickly and brings satisfying protein to the dish.

Then it’s all pulled together with a creamy blend of non-dairy cream cheese and coconut milk, and finally topped with a mix of mozzarella and cheddar for that perfect bubbly, cheesy topping.

How to Make Keto Green Bean Hamburger Casserole

Making this casserole is as easy as it gets. I start by sautéing onions and garlic in a bit of oil until fragrant, then stir in the ground beef and let it brown. Once it’s cooked through transfer it to a large mixing bowl, mix with soy sauce and paprika. I add the green beans, coconut milk and cream cheese, hald of both cheeses, stirring until smooth and creamy.

When everything is mixed together in the bowl, transfer to a baking dish. I love the ease of layering everything and topping it generously with shredded cheese.

Then it’s just a quick bake in the oven until everything is bubbling and golden on top. The result? A dinner that looks and smells amazing—and tastes even better.

Tips and Tricks for Leftovers

Leftovers of this dish are a blessing. I often make a double batch just for that reason.

It keeps beautifully in the fridge for up to four days and reheats well in the microwave or oven. Sometimes the flavors even deepen after sitting overnight, making it even better the next day.

For meal prep, you can portion it into containers for quick lunches. And if you’re freezing it, let it cool completely before storing in an airtight container—just remember to thaw in the fridge overnight before reheating.

Ideas for Variations and Uses

This casserole is endlessly adaptable. Sometimes I’ll add chopped mushrooms or a handful of spinach for extra greens.

If you want more heat, a pinch of chili flakes or a dash of hot sauce does the trick. You can also swap the ground beef for other proteins—whatever fits your preferences or pantry.

I’ve even used the leftovers as a filling for lettuce wraps or topped with a fried egg for a high-protein keto breakfast. It’s one of those recipes that’s as flexible as it is flavorful.
