As I have mentioned many times, I am a total Southern girl. I love casseroles, veggies, and easy homemade recipes. When I was a little girl, my best friend lived next door, and her mom made the best ground beef casserole with potatoes and green beans. I always wanted to eat dinner with them when she was making it.

When I was trying to brainstorm a new recipe idea, this came to mind. It’s funny how our minds work. I hadn’t thought of it in years, but suddenly, I started craving it.

I could easily make a low-carb version by omitting the potatoes and adjusting a few other ingredients in place of the cream of mushroom soup that she used in the sauce. Instead of canned soup, I used a mixture of heavy whipping cream and cream cheese to make a thick creamy sauce for the ground beef; then I topped it with green beans and cheese.

My little girls absolutely devoured it! Before I knew it, they had each put down two servings. I knew then it would be a hit!!

Ingredients

Ground beef – the protein for this casserole adds sso much yummy flavor

Here is a step-by-step pictorial to help you make the recipe. For the complete list of ingredients and detailed instructions, scroll to the bottom of the post to the printable recipe card.

Step 1: Brown the Ground Beef

Preheat your oven to your oven to 350°F.

In a large skillet, cook your ground beef over medium heat until browned. Next, you’ll want to drain it unless you prefer to keep the extra fat.

Tip: One of my favorite time-saving meal prep tips is to brown ground beef in advance and keep it in the freezer. I usually buy several pounds at brown it all at once. It makes recipes like this so quick and easy!

Step 2: Make the Yummy Creamy Base

Add the cream cheese to the browned ground beef and melt over low heat. Next, add the beef broth, heavy cream, Bragg’s Aminos (or soy sauce), and seasonings. Reduce the heat and simmer for 5 minutes, letting the mixture thicken slightly. Keep the lid off for it to thicken properly.

Tip: Make sure your cream cheese is at room temperature. Otherwise, it doesn’t blend as smoothly.

Step 3: Add Green Beans, Cheese, and Bake

Drain the green beans and dump them in the skillet. I used canned because that’s what I had on hand, but feel free to use frozen if you prefer. Top with generous amounts of cheddar and mozzarella cheese. Pop in the oven and bake for 25 minutes until melted, hot, and bubbly.

Step 4: Serve

As hard as it will be to wait, allow it to rest for 5 minutes before serving. Garnish with parsley or bacon crumbles. Bacon makes everything better, right?

FAQ’s

Do I Need a Cast Iron Skillet for This Casserole?

You can prepare this in any oven-safe baking dish or skillet, but I love using cast iron skillets for even heating from stovetop to oven. For this recipe, I used a 10.25″ cast iron skillet. Cast iron skillets last forever. I have several that were my grandmothers that are over 50 years old!

What’s the difference between 80/20 and lean ground beef?

The 80/20 refers to the meat’s fat-to-protein ratio. 80% lean ground beef contains 20% fat, creating juicier, more tender, and flavorful casserole recipes. Lean or 95% beef is lower in fat at 5%, making it healthier but drier! I always use 80/20 for the best flavor.

Can I make this casserole ahead of time?

Sure! It’s a great way to save time! Simply assemble the casserole, cover it tightly, and refrigerate it for up to 24 hours before baking. Then, when ready to enjoy it, pop it in the oven.

Is this Easy Low-Carb Ground Beef Casserole Gluten-Free?

Yes, it is naturally gluten-free. The main ingredients – ground beef, cream cheese, cheddar cheese, green beans, and seasonings – do not contain gluten. Make sure, though, to check the ingredients you use in your kitchen. Sometimes, gluten can be sneaky.

Can I make this casserole keto-friendly?

It already is at less than 4g net carbs per serving.

What Can I Serve With It?

I keep it simple and serve it with a leafy garden salad. It would also be yummy with Keto Cheddar Bay Biscuits or Creamy Keto Cauliflower Mash.

Storing and Freezing This Low Carb Casserole

It stays fresh in the refrigerator in an airtight container for 3-4 days.

Freezer:

For longer-term freezing, up to 3 months, wrap the cooled casserole tightly in plastic wrap, then foil. This prevents freezer burn. Dairy may cause a slight texture change upon thawing, but it won’t affect taste.

Thawing & Reheating:

Thaw overnight in the fridge before gently reheating in 325°F oven until heated through, about 30 minutes. You can also reheat it in the microwave.

While this low-carb version may be a bit different than my childhood friend’s mom’s original recipe with potatoes, it still has all the comforting flavors I remember. I hope your family enjoys this hearty, cheesy casserole as much as mine does!

Instructions

  • Preheat your oven to 350°F (175°C) degrees.
  • Grab a skillet and cook the ground beef. When it's done, use a strainer to remove any extra grease.
  • Add the room temperature cream cheese to the cooked beef in the skillet. Stir it until the cheese melts and mixes with the beef. Yum!
  • 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.
  • Reduce the heat to low and let it simmer. That means keeping it gently bubbling but not boiling too hard.
  • Drain the green beans and add them to the beef mixture.
  • Sprinkle some cheddar cheese and mozzarella cheese on top of the green beans.
  • Finally, pop the skillet into the preheated oven and bake it all together for 25 minutes. It will come out golden and bubbly.

    1. Hey Tashanta, it all depends on how much you want to add. Some may like to add more than others. Just remember that deviating from the recipe will change the nutritional information a bit. Hope you enjoy it.

    1. Hey Tracie, I’ve never used fresh green beans for this recipe. I would think that they would need to be cooked somewhat before using in this recipe. Let me know how it turns out.

  1. 5 stars
    I’ve just made this for about the 6th time since finding it and taking a chance. I can’t believe how delicious and simple this is! Perfect combo of flavors, we can never eat just one serving! Leftovers are sooooo yummy too!

    1. I don’t measure serving sizes by oz. Instead, I eyeball it to divide the casserole evenly into the number of servings listed at the top of the recipe card.

  2. 5 stars
    WOW! Made this today, exactly as posted, and my husband said, “This is absolutely fantastic!” 😲Now THAT is a compliment! He doesn’t give out compliments very often, 8f at all!! Also, the man who doesn’t like leftovers asked if there was enough for leftovers! 😲 I was SHOCKED!!

    This has become part of our regular keto meal rotation for the last 6+months, featured at least twice a month now (that’s saying a LOT since I rarely make the same recipe more than once for the last year and a half of this way of eating!).

    Quick and easy to throw together: CHECK!
    Delicious comfort food: DOUBLE CHECK!

    1. The number of servings is listed at the top of the recipe card. I divide the recipe evenly into that number of servings. The nutritional facts are per serving.
