Notes

  • Mix with ground pork: You can use ground pork in addition to beef for even more flavor. Use a mixture of 1 pound ground beef and 5 ounces ground pork if you would like to use pork.
  • Sugar-free tomato paste: Make sure your tomato paste is sugar-free. You can substitute it with sugar-free ketchup.
  • Using frozen green beans: If using frozen green beans, you do not need to thaw them. They will cook completely when baking the casserole.
  • Other veggies to use: Not a fan of green beans? You can still make this easy keto hamburger recipe! Try using cauliflower or broccoli instead. Broccoli is one of our personal favorites!
