An easy hamburger green bean casserole with mushrooms that uses all-natural ingredients and is so full of flavor it'll instantly become a family favorite. The low carb ground beef recipe makes a healthy main dish in less than 30 mins! It's a WHOLE LOTTA YUM!
Why You'll Love This!
During the summer heat when people simply crave more produce or possibly have garden veggies coming out of their ears, making a quick one dish stovetop casserole is an easy dinner that won't heat up your kitchen. This recipe is seriously a winner and one of our favorite casserole recipes on our site; our teen son literally ate half of the dish himself!
- The entire recipe cooks in under 30 minutes, just saute and then melt the cheese. So easy!
- The casserole sneaks in lots of veggies that picky eaters won't even notice.
- It uses all natural ingredients instead of using processed cream of mushroom soup
- Do you feel like you only eat green beans in the classic Thanksgiving green bean casserole? This unique main dish option is something you will love year-round.
- This is a gluten free, low carb, and keto hamburger casserole too.
Not sure what else you can do with green beans? Be sure to also try them in the air fryer and roasted with cheese.
While it might at first seem like the hamburger casserole recipe has a lot of ingredients, the majority of them are kitchen basics that most people probably have on hand.
- ground beef- We used an 80/20 blend since the higher fat content gives the meat even more flavor. A lower fat content ground beef would also work.
- green beans- Buying a bag of pre-washed and pre-trimmed green beans will save you time, if you use garden green beans or buy them by the bundle, you'll need to trim them first. Drained canned green beans or defrosted frozen green beans is another alternative.
- Worcestershire sauce - coconut aminos or wheat-free tamari make a good substitute
- cheese- We used a Colby-Jack blend, using one variety like cheddar or Monterey Jack tastes great too.
- other dairy- While we highly recommend full-fat sour cream and cream cheese for best flavor, low-fat should also work in this recipe.
Any quick-cooking vegetables make a good alternative to green beans, using zucchini to make a ground beef zucchini casserole is also delicious. Or get creative by increasing the mushrooms, using eggplant, or steamed microwave broccoli.
Ground turkey or ground chicken would be a great substitute for hamburger meat. Sometimes when we use leaner ground meats for beef we have to increase the salt and pepper seasoning a little bit.
- Gluten-Free- Be sure the brand of Worcestershire sauce you're buying is gluten-free, many brands are not. Both coconut aminos or wheat-free Tamari sauce can be used instead.
- Keto/Low Carb- Substitute coconut aminos or Tamari if you're following strict keto. Use full-fat dairy products since low-fat adds in fillers with hidden carbs. Likewise, be sure to shred your cheese from a block since pre-shredded cheese adds potato starch.
- Vegetarian- Beyond Meat makes a plant-based ground "beef" option for nights you want to cut back on meat.
- Lower fat option- While low-fat cream cheese, sour cream, and shredded cheese will also work, please don't use the non-fat varieties.
Step by Step Instructions
In a large skillet over medium heat, add 1 tablespoon of olive oil to heat. Brown the ground beef until cooked through, this will take about 5 minutes. Remove from heat and set aside. Reserve 1 tablespoon of grease to cook the vegetables in.
Saute the onion until they're just starting to soften in the 1 tablespoon of grease that was left in the pan; this will take about 3-4 minutes. Add the mushrooms to the pan and cook for 2 minutes more. Add in the green beans, garlic, and chicken broth, cook for 2-3 more minutes until the green beans and the other vegetables are softened.
Turn the heat down to medium-low and mix in the cream cheese and then sour cream.
Add the beef back into the pan along with the salt, pepper, dried thyme, and Worcestershire sauce. Stir gently to combine.
Sprinkle with the cheddar cheese over the top.
Place the entire dish in the oven and broil for 2 minutes until the cheese is browned and melted. Or, add a lid to skillet and cook for 3-4 minutes until the cheese melts. Using the stovetop, your cheddar cheese won't be crispy, but it will melt.
- Using a cast-iron skillet makes it easy to turn this into a one-pan meal since it can go in the oven too. If you don't have a cast iron skillet, use whatever kind you have and then transfer it to an oven proof baking dish or casserole dish.
- Instead of broiling the cheese - leave it in your skillet, turn the heat down to low, and cover the hamburger casserole, until the cheese is melted for 3-4 minutes.
- Be sure to drain off the grease after cooking the hamburger meat, but don't forget to save a little for cooking the veggies.
- Add extra broth if you prefer a saucier casserole.
Can You Freeze Casseroles?
While we haven't tried freezing this ground beef casserole recipe, generally, casseroles with dairy in them don't freeze well since it often turns grainy or separates when it gets defrosted. Freezing casseroles is best left for ones that don't have added cream or sour cream in them. It's best to make it fresh and eat it within 4 days.
What to Serve it With?
Since this already includes a protein, dairy, and 3 different vegetables, it could technically be considered a one-dish skillet recipe. Our favorite sides are something simple like a green salad, herbed potatoes, or bread (if you can eat bread).
Can it be Doubled?
To double the recipe, use a larger skillet and then transfer all of the ingredients to a 9x13 baking pan before melting the cheese.

added more cream cheese and sour cream Lil more thyme and garlic was delish oh a Lil more green beans too
This was very good. I had some grape tomatoes that needed to be eaten, so I cut them in half and sautéed them for a few minutes with a lid, so they would break down and soften. . I also added half of a diced bell pepper. I sautéed everything ahead of time and then put the ingredients together, except for the cheese, in the iron skillet and baked it for 15 min at 350, then added the cheese for another 15 min. Then broiled it for 5 min. Perfect but very hot. Had to let it sit for 5 minutes.
Really love this recipe. Make it a lot.
This was really good!, I didnt have any cream cheese, and replaced it with cream of chicken/mushroom soup, almost a whole can, green beans, canned carrots, garlic minced , bell peppers chopped, , very good! Thank you!
We made this dish last night and it was delicious! We didn’t have any thyme so we left it out and no Worcestershire sauce so we subbed Dale’s low sodium. We have added to our keepers recipe box !

Finally getting back to Keto. We really enjoyed this recipe. I cooked the onions with the hamburger because we like ours cooked through. I was out of thyme so I used Italian seasoning. We loved the use of Co-Jack cheese. I will definitely be making again!

This recipe was delicious I must say. I have tried a different recipe in the past that I really like too. It calls for whipping cream instead of sour cream with the cream cheese. I substituted basil instead of thyme as I didn’t have any . I used 1 cup mozzarella and 1 cup of marble to my dish and let it broil for a few minutes in the oven. I definitely will make this again. Thank you so much .

If you like the onions with less crunch you may want to cook them a little longer before adding the mushrooms. Also, a little shredded cheddar within the meat mixture gives it an added bonus.
