Preparing Ground Beef - A close-up image of ground beef being cooked in a cast iron skillet. How to Make This Easy Low-Carb Casserole

Step 1: Preheat your oven to 350°F. In a large skillet, cook the hamburger meat over medium heat until it’s browned. Make sure to break it up into small pieces as it cooks. You can add some salt and pepper for extra flavor if you’d like! Strain your ground beef and return it to the skillet.

Tip: I keep ground beef already browned in the freezer. It makes recipes like this so quick and easy. You can find the details in 5 Meal Prep Ideas That Save You Time on a Keto Diet.

Step 2: It’s time to make the creamy sauce. Add the cream cheese to the cooked beef in the skillet. Pour the beef broth, heavy whipping cream, Bragg’s Aminos, and seasonings.

Step 3: Reduce the heat to low and let it simmer. As it simmers, the liquid will reduce, and the mixture will thicken.

Tip: The cream cheese will mix best with the ground beef if it is at room temperature.

Step 4: Add the green beans to the ground beef mixture. Don’t forget to drain them first, as it will add moisture to the sauce.

What is the Best Cast-Iron Skillet?

I prefer to use a cast-iron skillet when I make this keto recipe with ground beef, as it goes from stove to oven with only one dish. If you don’t have a cast-iron skillet, they are affordable and last forever. This 10.25 Cast Iron Skillet works perfectly with this recipe.

Do I have to have a Cast Iron Skillet to Make this Keto Ground Beef Casserole?

No, it is not necessary. Any skillet will do. If your skillet isn’t oven-safe, transfer the keto ground beef mixture to a baking dish before adding the green beans and cheese. Most everyone has casserole dishes that can be used for any skillet meal if a cast-iron skillet isn’t available.

Can I use any ground beef for this casserole?

Absolutely! You can use any ground beef you prefer, whether lean or with a higher fat content. Just keep in mind that higher fat content can add more flavor and richness to your casserole.

How do I make sure my casserole doesn’t turn out dry?

To prevent your casserole from turning out dry, make sure to use enough moisture-rich ingredients like heavy cream and cheese. You can also add a bit of chicken or beef broth to keep it moist. Additionally, avoid overcooking the casserole, as it can dry out the meat.

Can I add other vegetables to my ground beef casserole?

Absolutely! You can add any low-carb vegetables you enjoy. Some popular options include bell peppers, zucchini, spinach, or diced tomatoes. Just make sure to adjust the cooking time accordingly, as different vegetables may require other cooking times.

How long does it take to bake a keto ground beef casserole?

The baking time can vary depending on the recipe and the thickness of your casserole. As a general guideline, most keto ground beef casseroles bake at around 350°F (175°C) for 25 minutes. However, it’s always best to follow the specific recipe instructions for accurate baking times.

Can I make this casserole ahead of time?

Absolutely! Making the casserole ahead of time can be a great time-saving option. You can assemble the casserole, cover it tightly, and refrigerate it for up to 24 hours before baking. This way, you can pop it in the oven when ready to enjoy it.

Is it Gluten Free?

Yes, beef and green bean casserole can be gluten-free. It is important to check all of the ingredients you use in your kitchen to ensure each is gluten-free.

  • 1 pound ground beef
  • 3 ounces cream cheese
  • 1/2 cup beef broth
  • 1/2 cup heavy whipping cream
  • 2 tsp Bragg's Aminos
  • 1 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 2 cans green beans, drained
  • 3/4 cup cheddar cheese
  • 3/4 cup mozzarella cheese
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper


  • First, turn on your oven and set it to 350°F (175°C) degrees.
  • Next, grab a cast-iron skillet (a sturdy pan) and cook the ground beef in it. When it's done, use a strainer to remove any extra grease.
  • Now, it's time to make things creamy and yummy! Add the cream cheese to the cooked beef in the skillet. Stir it until the cheese melts and mixes with the beef. Yum!
  • Time to add some more flavor! Pour in the beef broth, heavy whipping cream, Bragg's Aminos, garlic powder, onion powder, and a pinch of salt and pepper. Stir everything together well.
  • Bring the mixture to a boil by turning up the heat a bit. Keep an eye on it and let it cook on medium heat until it starts to thicken up a little. This will make the casserole nice and creamy.
  • Now, reduce the heat to low and let it simmer. That means keeping it gently bubbling but not boiling too hard.
  • Great job! The ground beef mixture is thick and ready. Now, it's time to add those green beans! Open the cans and drain the water from them. Place the green beans on top of the beef mixture in the skillet.
  • Sprinkle some cheddar cheese and mozzarella cheese on top of the green beans. This will make the casserole extra cheesy and delicious!
  • Finally, pop the skillet into the preheated oven and bake it all together for 25 minutes. It will come out golden and bubbly.

    This is one of my most favorite recipes. I make it often! I usually add a little onion powder and use reduced sodium tamari sauce instead of coconut amino. I also double it and sometimes replace 1 can of green beans with some mushrooms. So tasty! ❤️

    1. So glad you love it! I love hearing how people take and personalize these recipes! They all sound so good!

    1. Hey Kate, I haven’t used fresh green beans in this recipe, so I cannot tell you for certain. Softening them up a little seems to make sense, but again I have never tried fresh green beans. Let me know what you decide and how it turns out.

    1. Hey Ebony, everyone’s serving sizes can be different. I divide this up into 8 equal servings. If you would like, you can divide it into 4 servings but will have to adjust the nutritional info. Hope you enjoy it!

    Soooooo good! Non-keto hubby approved!
    I didn’t have any aminos and wasn’t sure what to sub. Wound up using Worcestershire sauce. Yummy!
    Thanks so much!

    I love this recipe, I make it often! I usually make tater tots on the side for my family because it reminds me of tater tots casserole as well.

    1. Great idea, Jessica! I am not a fan of cooking multiple options at dinner since our kids aren’t low-carb. Great way to add something to the meal so the entire family can enjoy it!
