How to Make Keto Beef Stroganoff Casserole
Brown the ground beef in a large pot, then remove and set aside.
Add the butter to the pan and sauté the mushrooms over medium heat, until you have some good color on them.
Remove and sauté the onions for a few minutes. Then add in the garlic for about 20 seconds. Careful not to burn the garlic!
Pour in the white wine to deglaze the pan, scraping up any brown bits of flavor.
Preheat your oven to 400F.
Add in the remaining ingredients, except for the cheesy mashed cauliflower and stir until well combined.
Stir in the ground beef and sautéed mushrooms and allow to cook for 5 minutes.
Add the cheesy mashed cauliflower over the top in large dollops, and spread using an offset spatula and bake for 10 minutes.
The top of the casserole will be slightly browned when done. Allow to cool slightly before cutting into and serving.
Are There Carbs in Keto Stroganoff?
Traditional stroganoff that uses pasta has way too many carbs to even consider for those on Keto or low carb diets.
With this Keto beef stroganoff casserole, that worry is taken away by replacing the pasta with cheesy cauliflower, which adds so much flavor but removes all but 5 net carbs per serving!
Another key component to the texture and richness of this Keto stroganoff recipe are the baby bella mushrooms. Of course you can use any of your favorite mushrooms in their place.
Are Mushrooms Keto?
Mushroom are excellent for Keto and low carb diets. The amount of carbs depend on the variety of mushroom but for baby bella mushrooms, there's only one net carb per ½ cup serving.
Not only are mushrooms low carb they are loaded with nutrients. They're a great source of antioxidants, vitamin B, potassium and riboflavin. To read all about the health benefits of mushrooms, check out this article.
Tips for Low Carb Beef Stroganoff
- You can make this recipe a day before you need it. Just assemble it and store in the fridge. Baking time will increase due to it being chilled.
- If you don't have Mascarpone, you can use cream cheese. The macros will be different because there are more carbs in cream cheese, so make sure you adjust accordingly.
- If you have leftovers, this casserole will freeze well. Place it in an airtight freezer safe container and store up to a couple of months. To thaw, place in the fridge overnight.
- Because mushrooms shrink considerable when cooked, be sure to slice them rather thick, preferable ¼ inch.
- If you'd rather skip the white wine, just substitute with additional broth.
- If you want extra cheesiness, add a little shredded cheddar to the top, right before you remove it from the oven.
- Beef bone broth can be used to substitute the beef both in this recipe.
