Hi! Do you think this could be cooked in a crock pot?
I make these for Christmas presents! Everyone luvs them. I add sautéed onions, mushrooms and red peppers. DELICIOUS!!
Perfect!!!
I made this for Christmas breakfast and it was incredible. I followed the recipe exactly. Delicious!
A wonderful place to start — and when I took to Bible study this morning it was very well received! I had not used Bisquick in YEARS. To avoid lumps when adding the Bisquick, I add it into the sausage after draining and it incorporates pretty much wihtout lumps of any kind I diced up ~2cups of portabella mushrooms & cooked in microwave ~45 seconds and added that + liquid to the sausage mixture along with some dried onions; Complete Seasoning and Adobo. Grated up New York Sharp Cheddar & added that. In separate bowl mixed up 8 eggs & half & half (subbed that for the milk) then poured into sausage mixture.
I froze my squares. All gone. Ready to bake another batch and printed the recipe so I can make many more batches to come. This is a keeper!
My picky grandson LOVES this recipe. Made just as it is printed!
