    Oh my good golly gosh. My 6 year old nephew is a very picky eater and he destroyed this casserole. I have not made anything from this site that wasn’t fabulous. Thank you again Lauren.

    This is the best breakfast casserole I have ever had. This recipe is a keeper. I followed it to a T. Mine took 1 hour and 15 minutes to cook. I made it Christmas morning for 10 people and it got rave reviews.

  3. This recipe was delicious. I cut the recipe in half since was just for two people and it was amazing. I added a bit more red and green pepper than it required for halving the recipe and it was just simply delicious. I will make it again and placed in my favorite recipe file.

  4. 5 stars

    Thank you for sharing this recipe!
    I will definitely make this again and again!
