Nicole says
Where did you find sugar free tomato paste? I am making this recipe tonight but don’t see any in stores.
Em Beitel says
Hi Nicole! The can itself might not say 'sugar-free' on the front, but generally the organic tomato paste varieties won't have any sugar added (it will say no sugar added on the back of the label). You can also order tomato paste if you're not able to find it! Sugar-free ketchup works too! Hope this helps - please enjoy!
Linda Holland says
I don't like the bitter taste of tomato paste. Can I use tomato sauce. Do I drain the hamburger grease or leave it in?.
Em Beitel says
Hi Linda! You can absolutely use tomato sauce if you prefer. Tomato paste has a thicker consistency, though, so a better choice might be ketchup or tomato puree. Please enjoy!
Ernesto Fuentes says
Hello, do you drain the grease from pan after you're finished browning the meat? Thank you
Em Beitel says
Hi Ernesto! There is no need to drain the beef! Thank you for your question and please enjoy!
Lisa McBroom says
Should it actually be a 9 x 13 pan and not 8 x8? Thank you
Em Beitel says
Hi Lisa! Yes, that was an error on our part. We recommend a 9x13 pan. Thank you!
Johnie Pitts says
I make this same recipe except I spread mashed potatoes over the top then I put it in the oven at 375° for 45 minutes. I know to be "Keto" correct you wouldn't use the mashed potatoes but I've been fixing this for my family for years. It's a family favorite
Em Beitel says
That sounds absolutely delicious! If you're not on a keto diet that sounds like a perfect way to enjoy this dish. Thank you for sharing with us, Johnie!
Gail Patterson says
You could still be keto using caulimash. Both ways sound great!
Emily O’Brien says
You didn’t answer Lisa Holland’s 2nd question about whether to drain the grease from the meat or leave it in. I,too, would like an answer? Thank you for your consideration.
Em Beitel says
Hi Emily - I apologize! There is no need to drain the beef. Thank you and please enjoy!
