I know for many of you the arrival of the new year signals a return to stricter low-carb or more carb-conscious eating, so I always like to start out the year with a knock-your-socks-off low-carb recipe. And it seems like when it’s cold outside people crave low-carb casseroles, right? This Low-Carb Ground Beef Stroganoff Casserole is a recipe that was inspired by my Low-Carb Turkey Casserole with Mushrooms, Mozzarella, and Cauliflower Rice that so many people have loved, but there are a few twists to this one that give it much more of a beef stroganoff vibe.

When I was growing up Beef Strofanoff was one of my favorite family meals, and we absolutely swooned over this casserole when we tested the recipe. (I love a good low-carb ground beef casserole and I gobbled up my share of the leftovers, which is always the sign of a winner since food bloggers often have the unique problem of too much food in the fridge.)

When I  came up with the turkey and cauliflower rice casserole recipe with Kara we had to test it over and over to get a version that wasn’t watery. Sauteeing the cauliflower rice over very high heat to evaporate some of the water is one of the tricks to get rid of extra liquid, so please don’t skip that step. And another step that might seem finicky is making a concentrated beef stock that’s been cooked down so it’s thick; then that gets mixed into the sauce. Again, please do not skip that step.

This low-carb ground beef casserole is a casserole recipe with a few steps to put it together, but I promise it’s worth the trouble, and it makes enough that you should have some leftovers! Happy New Year everyone, and enjoy!

How to make this recipe:

(Scroll down for complete printable recipe with nutritional information.)

  1. Combine 1 tsp. Better Than Bouillon Beef Base (affiliate link) or a beef bouillon cube with 1/4 cup water, then simmer on the stove until it’s reduced to 1 tablespoon. (Edit: Shirley from Gluten Free Easily tells me that Better than Bouillon no longer guarantees their products are gluten-free, so that brand won’t work for people who have to avoid gluten.)
  2. While the beef stock reduces, brown the ground beef well.
  3. Put ground beef in the casserole dish, add a little more olive oil, then brown the quartered mushrooms and add to the casserole dish when they’re done.
  4. Mix together the sour cream and mayo and when the beef stock has reduced (and cooled a bit) pour it into that mixture.
  5. Heat a little more olive oil if needed and brown the onions.
  6. Then add the cauliflower rice, steak seasoning, salt, and pepper and cook about 3 minutes at very high heat so some water from the cauliflower is evaporated.
  7. Put the cauliflower rice mixture into the casserole dish.
  8. Mix the Mozzarella, Parmesan, and a little more steak seasoning into the sour cream-mayo-beef stock mixture.
  9. As you can see, we mixed together the ground beef, mushrooms, cauliflower rice-onion mixture, and the sauce right in the casserole dish, then patted it down and wiped off the edge of the dish.
  10. Top the casserole with a little more grated Mozzarella cheese and bake 30-40 minutes, or until it’s bubbling and nicely browned on the top.
  11. Serve hot and enjoy!
  12. This kept well in the fridge and can be reheated in the microwave or in a pan on the stove.

Total Time 1 hour 10 minutes

Start the new year out right with this amazing (and low-carb) Ground Beef Stroganoff Casserole with Cauliflower Rice!


  • 1 1/2 lbs. ground beef
  • 2 T olive oil
  • 1 lb. mushrooms, washed, drained dry, and cut into quarters (I used brown Crimini mushrooms)
  • 1 onion, chopped small
  • 4 cups cauliflower rice (see notes)
  • 1 tsp. steak seasoning
  • salt and fresh-ground black pepper to taste
  • 1 cup grated Mozzarella

Sauce Ingredients:

  • 1 tsp. Better Than Bouillon Beef Base (or a beef bouillon cube) mixed with 1/4 cup water and then simmered to reduce to 1 tablespoon thick stock
  • 1 cup sour cream
  • 1/2 cup mayo
  • 1 cup grated Mozzarella cheese
  • 1/4 cup freshly grated Parmesan cheese
  • 1/2 tsp. steak seasoning


  1. Preheat oven to 375F/190C. Spray a large glass or ceramic casserole dish with non-stick spray or brush with a little olive oil. (I used an oval-shaped dish that's 13 inches long and 10 inches wide at the widest part.)
  2. Mix the Better Than Bouillon Beef Base (or a bouillon cube) with 1/4 cup water; then simmer the mixture on the stove in a very small pan until it's reduced to 1 tablespoon thick stock. Let it cool.
  3. Heat a couple of teaspoons olive oil in a large heavy frying pan and cook the beef over medium-high heat until it's completely browned, breaking apart with the turner as it cooks. Put browned beef in the casserole dish.
  4. While beef browns, wash mushrooms and spin dry in a salad spinner, or let them drain well.
  5. Chop up the cauliflower and pulse in the food processor to make cauliflower rice if you're not using packed cauliflower rice.
  6. Cut drained mushrooms into quarters (or halves if they're small.) Heat a couple more teaspoons olive oil in the frying pan and cook mushrooms over medium high heat until they have lost all their liquid and are slightly browned. Put mushrooms in the casserole dish.
  7. Mix the sour cream and mayo and add the cooled and reduced stock and stir together.
  8. While mushrooms cook, chop an onion into small pieces. Heat two more teaspoons oil in the frying pan (if needed), add the onions, and cook over medium-high heat until onions are softened and starting to brown.
  9. Add the cauliflower rice, 1 tsp. steak seasoning, salt, and pepper to the frying pan with the onions. Turn heat to high and cook about 3 minutes, or until cauliflower is partly cooked and some liquid from the cauliflower has evaporated as steam.
  10. Add the onion-cauliflower rice mixture to the casserole dish and gently combine all the ingredients.
  11. Mix the 1 cup grated Mozzarella, Parmesan, and 1/2 tsp. steak seasoning into the mayo-sour cream mixture.
  12. Gently mix the sauce into the cauliflower rice-ground beef mixture in the casserole dish, patting it down when all the ingredients are well combined. Wipe off the edge of the casserole dish if it's messy.
  13. Top the casserole with 1 cup (or more) grated Mozzarella.
  14. Bake casserole 30-40 minutes, or until it's bubbling hot and the top is lightly browned.
  15. Serve hot. Leftovers of this will keep in the fridge for at least a week. It can be reheated in a microwave or in a small pan on the stove.


You can buy Better Than Bouillon Beef Base (affiliate link) at Amazon.com if you don't find it in your store. I used packaged fresh cauliflower rice. If you're chopping cauliflower in a food processor to make the cauliflower rice, start with 6 cups cauliflower pieces.

  1. Have you tried your recipe with ground turkey?

    • No, but I can’t imagine it would be good. I would probably still use the beef bouillon unless you have a good-flavored turkey bouillon. I’d love to hear how it works.

  2. Made this tonight and it turned out great! I reduced a can of beef consume soup instead of bouillon because that’s what I had for the beef flavor. Other than that, I followed the recipe. It was super delicious, satisfying and filling!
