Is Pepper Casserole Keto Friendly? 

As with most vegetables, bell peppers are healthy and low carb. As far as pepper casserole being keto friendly, because this casserole dish has white rice in it, its not a low carb dish. Instead of rice, try to substitute white riced cauliflower or even quinoa. Whether or not this casserole is a great choice for your particular diet needs is up to you.

  1. Can you make this ahead of time and freeZe?!

    1. Nicole, I havent personally frozen this dish to give you a custom experience (my freezer is always packed w/ like ice cream and waffles, haha!) but on some research, it appears it should be fine, however cooked rice can get “mushy” or a bit dry (as left over rice does) when frozen and then unfrozen and recooked. You might be best just freezing the peppers and sausage portion and adding fresh rice at the cook level if possible.

  2. This recipe is a definite “keeper”. I used Sweet Italian Turkey Sausage, Jasmine Rice and Pepper Jack Cheese. It was delicious!

      Thank you for your awesome feedback! So glad you enjoyed this pepper casserole!

  3. I have made this several times now using turkey breakfast sausage since I must eat low fat and low salt. I also hate oregano so I use 1/2 teaspoon each of rosemary, basil thyme and sage. It has worked well. Salt free tomatoes and brown rice are the only other changes. Really love sausage stuffed pepper casserole!
