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 that also has mushrooms, cauliflower rice, and cheese.

This ground beef stroganoff 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!
