As a Southern girl who loves casseroles and homemade recipes, I fondly remember my best friend’s mom making a delicious ground beef casserole with potatoes and green beans. The smell filled the house, and it was always my favorite meal. Those dinners always felt so cozy.
This dish came to mind recently, and I could not wait to make it. I wanted to create a low-carb version that still captures all the flavor. By omitting the potatoes and tweaking a few ingredients, I managed to whip up this easy keto hamburger casserole that my family absolutely devoured.
I could easily make a low-carb version by omitting the potatoes and adjusting a few other ingredients instead of the cream of mushroom soup 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!!

How to make Keto Ground Beef Casserole with Green Beans
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: Preheat your oven to your oven to 350°F. Start by grabbing your favorite skillet—mine’s a cast iron that’s been in the family for years! There’s just something about it that makes everything taste better.
Brown the ground beef over medium heat, and don’t rush this step! Let it cook until nicely browned, and you see those little crispy bits forming. Trust me, those bits are pure flavor gold. After that, go ahead and drain off the extra fat unless you like a little extra richness in your dish—totally your call!
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: Once your ground beef is browned and smelling, add the softened cream cheese. Toss it in and stir until it melts into the beef! Then, pour in your beef broth, heavy cream, and a splash of Bragg’s Aminos (or soy sauce if that’s what you have). Don’t forget the seasonings—they’re the secret to all that flavor!
Let it simmer on low for about 5 minutes, uncovered, so it thickens up just right.
Tip: Make sure your cream cheese is at room temperature. Otherwise, it doesn’t blend as smoothly.
Step 3: 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: I know it’s tough, but trust me—you’ll want to let this casserole rest for about 5 minutes before diving in. This little break helps all those amazing flavors combine and lets the casserole set. While waiting (and trying not to sneak a bite), why not get creative with some toppings? A sprinkle of fresh parsley adds color, or go all out with crispy bacon crumbles—because, let’s be real, bacon makes everything better!
Top Tips for making this recipe
Browning the Ground Beef
When you’re cooking the ground beef, don’t crowd it in a small skillet. If it’s packed in too tight, it won’t brown properly—it’ll steam instead, and that’s not what we want. Let it get a nice brown crust before you flip it.
Melt Your Cream Cheese
For a smooth, creamy sauce without lumps, make sure the cream cheese is at room temperature before tossing it in the pan. Cold cream cheese doesn’t melt well and can make your sauce lumpy. If you’re in a hurry, pop it in the microwave first and cut it into small pieces to help it melt faster and more evenly.
How to Check if Your Sauce is Perfectly Thickened
To check if your sauce is thickened perfectly, dip the back of a spoon into it and run your finger through the sauce on the spoon. If the line stays clear and doesn’t fill in quickly, it’s ready! The sauce should be creamy and coat the spoon nicely.
What to Do if the Sauce is Too Thin
If your sauce seems a bit too thin, don’t worry—it’s an easy fix! Keep simmering it on low heat for a few more minutes, stirring occasionally. This will help some of the liquid evaporate, making the sauce thicker. If it’s still not thickening up, you can mix a tiny bit of extra cream cheese into the sauce or even sprinkle in a small amount of shredded cheese. Both will add thickness and extra creaminess.
What to Do if the Sauce is Too Thick
If your sauce looks too thick and you’re having trouble stirring it, just add a splash of beef broth or heavy cream. Start with a little, stir it in, and see if it reaches the consistency you like. You can always add more liquid, but it’s harder to remove it, so go slow!
FAQ’s
What’s the Best Pan for This Casserole??
Any oven-safe dish or skillet will do the trick. But if you’ve got a cast iron skillet lying around, definitely use it—it heats evenly and adds a little extra something to the dish. I used my trusty 10.25″ cast iron skillet for this recipe, and I swear by it.
Fun fact: Some of mine are over 50 years old and were passed down from my grandmother. They’re still going strong!
What’s the difference between 80/20 and lean ground beef?
What’s the difference between 80/20 and lean ground beef (such as 95% lean)? 80/20 refers to the meat’s fat-to-protein ratio. 80% lean ground beef contains 20% fat, creating juicier, more tender, and flavorful keto casserole recipes.
Can I make this casserole ahead of time?
Absolutely! If you’re like me and love having dinner ready to go on those crazy, busy nights, this casserole is a lifesaver. Just put it all together, cover it up, and stash it in the fridge for up to a day. Then, when you’re ready for a cozy, no-fuss dinner, pop it in the oven. It’s like having a homemade meal on standby—perfect for those days when you’re running around like crazy!
Is this Easy Low-Carb Ground Beef Casserole Gluten-Free?
Yep, it sure is! This casserole is naturally gluten-free since we’re using simple ingredients like ground beef, cream cheese, cheddar, and green beans. Just double-check your ingredients, especially any seasonings or sauces, because gluten can sneak in where you least expect it.
Can I make this casserole keto-friendly?
Good news! It already has less than 4g net carbs per serving, so you can enjoy this delicious low-carb beef bake without worrying about going off plan.
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 Your Low-Carb Casserole
Refrigeration:
After you’ve enjoyed your casserole, store any leftovers in an airtight container in the fridge. It’ll stay fresh and tasty for about 3-4 days. Perfect for those quick meals later in the week!
Freezing:
If you want to keep your casserole for a bit longer, freezing is a great option. Once cooled, wrap it tightly in plastic wrap and then foil. This double-wrap helps prevent freezer burn. It should stay good in the freezer for up to 3 months. Just a heads-up—dairy might slightly alter the texture after thawing, but don’t worry, it won’t affect the flavor!
Thawing & Reheating:
When you’re ready to enjoy your frozen casserole, let it thaw overnight in the fridge. To reheat, pop it in a 325°F oven for about 30 minutes until it’s heated all the way through.
If you’re in a hurry, you can use the microwave too. Microwave cooking time will depend on how much you are warming. If I rewarm an individual serving, I always start in 30-second intervals, stirring in between, to make sure it warms up evenly.
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!

Our favorite Keto recipe! I use 8 ounces of sliced portobello mushrooms since we don’t like canned green beans. Just the best!!!
I’m glad it’s your favorite!
I’m not Keto, but I saw this recipe and I thought it sounded good. It definitely did not disappoint. It was absolutely amazing!!! I used two steamer bags of green beans instead of cans and I added a boat load of Trader Joe’s onion salt (because it’s amazing in everything).
Awesome! Sounds delish.
This stuff is delicious! I have to put tater tots on top of half it for my husband. He thinks it just tater tot casserole, lol!
Great idea for the non-keto eaters in your family.
My husband and I loved it. We will be using this again!
I’m so glad ya’ll loved it!
Yummmmm reminds us of stroganoff with green beans as the noodles.
Loved it a ton, will include in our winter repoirtoire of casseroles.
Thank you. We added additional pepper, maybe add crushed red pepper next time.
You’re so welcome! I’m glad you enjoyed it.
Thank you for such a simple and delicious recipe! I am new to keto and I made this today, but added 1/4 cup of chopped onions and it turned out very tasty. !
I’m glad you enjoyed it!
I added chili flakes to give a little heat.
That works!
I was unsure of this recipe before trying it, but I was hungry and had all the ingredients! Well, I was surprisingly pleased with how it turned out! It was awesome! Total comfort food. The only change I made was I added some steamed broccoli and one can of green beans.
I’m glad you enjoyed it!
Do you know if you can make and freeze this recipe?
I’ve included that information in the post.
I’ve just made this recipe as written and it is delicious! Trying to portion it out into 8 servings to freeze for later, about how much is one serving?
I never really measured it out. I just divided it into eight servings as we ate it.
This was delicious!! Made exactly as written and my family LOVED it.
That’s awesome! Glad your family loved it.
This is delicious!! That being said, dividing this recipe into 8 servings is almost impossible. I divided it into 6 and it was like 5 heaping bites at max. Unfortunately for enough to be full, the carbs are pretty high 😥
I make a nice garden salad to go with it and the fat content from the casserole always keeps me full for a long time.
Tried this last night. Was really good but would double recipe as it wouldn’t feed 4. Thanks
I’m glad you enjoyed it!
I added onion and celery…SO good! Thank you for sharing!
You’re so welcome!
NO canned green beans !! Use fresh
Sure, you can do that. I love to use fresh green beans but, with four kids, I don’t always have the time to use fresh.
Thanks Kasey! This was the second keto meal I ever made when I began the keto journey back in July. Everyone, this is such a building block of a recipe. You can replace the green beans with squash, onions, celery, peppers or mushrooms. You can make it slightly different every week so your family doesn’t get bored with it.
You’re welcome, Amanda. I love this recipe and I’m glad you do, too!
Could probably just melt cheese an all on stove top as well and avoid the extra step
You probably could but, in testing the recipe, baking it was the best outcome.
Did u use regular Beef broth or Beef bone broth?
I use beef broth.
