Normally, the 5 components of a casserole are protein, starch, vegetables and cheese. However, if you’re following a low carb or keto diet the starch has got to go!

Luckily you can use one of my favorite keto casserole recipes using lean ground beef that is still hearty and delicious and perfect for meal prep.

🐄Ingredients You’ll Need To Make Keto Ground Beef Casserole

  • Lean Ground Beef: You could use a ground beef with a higher fat content, but I find that sticking with 90% or more keeps the casserole from getting too watered down with fat in the beef mixture. If you have meat with a higher fat content, feel free to drain it beforehand or, you could also try using ground turkey or ground bison for this recipe. 
  • Canned Green Beans: This is a quick way to add a dose of nutrients from low carb vegetables in this casserole. 
  • Cream Cheese: This will pull together all the ingredients and make everything creamy and delicious.
  • Coconut Aminos or Soy Sauce: Either of these go well with a beef dish adding a great depth of flavor. Coconut Aminos are a great gluten and soy free alternative. 
  • Dijon Mustard: Adds another layer of flavor that goes fantastic with ground beef.
  • Grated Parmesan and Cheddar Cheese: The combination of these 2 cheeses makes this true keto comfort food when it gets melted on top.
  • Crumbled Bacon: This is optional but really makes this keto casserole pop!

📖How To Make Keto Ground Beef Casserole

1️⃣ Preheat Your Oven: Preheat your oven to 350 to prepare for the skillet to go in the oven.

2️⃣ Cook Ground Beef and Onions: Heat avocado oil in an oven safe skillet over medium high heat. Add in sliced onions and saute for 5 minutes or until they begin to turn translucent. Add in ground beef and cook until no longer pink.

3️⃣ Stir In Seasonings: Cut cream cheese into blocks and add to ground beef and onion mixture as well as the Coconut Aminos, Coarse Grain Mustard and black pepper. Turn heat down to medium and gently stir until cream cheese is melted and everything is combined. Once mixture is combined, fold in drained green beans.

4️⃣ Top and Bake In Oven: Evenly top green bean casserole with shredded cheddar, crumbled bacon and Parmesan cheese. Add skillet to preheated oven and bake for 10-12 minutes or until cheese is melted on top. Serve hot. 

🔁Variations

  • Bulk up the veggies in this dish by tossing in some cauliflower rice or sautéed mushrooms into the mix before baking.
  • Make this recipes using fresh green beans. Just make sure you blanch them first to make sure they are par-cooked before adding to the meat mixture.
  • Cheddar and parmesan are a great mixture of cheese to add, but feel free to use your favorites including pepperjack, or gouda.
  • This dish does not need to be made in a cast iron skillet. You can prepare the casserole, then transfer it to a casserole dish and bake in the oven.
  • Season this casserole with your favorite herb blend or a mix of salt, pepper, and garlic powder.

Storing Leftovers

If you have any leftover keto hamburger casserole, store it in an airtight container in the fridge for 3-4 days. Reheat in a skillet over medium heat until warmed through.

Can you make it ahead? This recipe can be made 24 hours ahead of time. Follow the instructions up until adding to the oven. Wrap the casserole in plastic wrap once cooled, then bake in the oven when read.

  1. Hi there!
    Where does the minced garlic go in this recipe? I noticed it listed in the ingrediants, but cannot for the life of me find where it is noted in the instructions? Does this maybe go into the saute onion step?

Only Change I made was to add about 3tbs of Worcestershire sauce and to sauté about a quarter cup of zucchini and red bell pepper with the onions.. (to add more veg) Will absolutely be making again! Thx so much.

      I subbed the soy sauce for Worcestershire sauce. I also used a low carb honey mustard instead of Dijon mustard. I added some French fried onions on top when I put it in the oven because they weren’t very high in carbs. I only used about half the container. SO GOOD. I’ll be making it again!

  6. Karen, thanks for the added spices. It came out rather bland, so I added the Rotel and a few spices. I love it. Thanks to both of you!!!
