I came up with this recipe for people who love sweet things but also like a little heat in their lives! If preferred, replace the shrimp with chicken.

I followed the recipe exactly. It was delicious!
Anne Swanson
I made this today; I added onions and used fresh mushrooms and spinach. I extended the cooking time to extra 25 minutes so that the liquid and eggs could set firmly. Pleasantly surprised with the taste and presentation. I will definitely use this recipe in the future.

Merry Christmas! This is perfect for Christmas morning. I made it almost exactly to the recipe, but always vote for fresh ingredients whenever I have them, so I used 8 oz chopped fresh mushrooms, and roughly 10 oz. chopped fresh baby spinach. I added a chopped onion to the sausage, while cooking, along with half of the chopped mushrooms, added the remaining mushrooms at the very end without cooking them too much. I used four XL eggs, took the casserole out in the morning, roughly 1.5 hours before putting it into the oven while my teens were still sleeping and cooked covered in foil for about 45 minutes and another 20 minutes uncovered. Everyone like it a LOT!!Thank you!!

I used fresh mushrooms vs. canned. Added more eggs, cheese and bacon, it was a crowd pleaser.
Stephen Fleming

Phenomenal! Having it for Mothers Day breakfast. Fresh mushrooms instead of canned for the win! Yummm!!
Caitlin Stephenson
Now a requested addition at church breakfasts

This was excellent!!

I only changed the length of baking. It was as labor intensive as lasagna or anything else and totally inedible. Forget “popping it in the oven” on Christmas morning. Even after letting the casserole get to room temperature I had to bake it for an extra 25 minutes for the egg/cheese mixture to set.

Can’t believe how delicious this was. Made according to directions except sautéed fresh mushrooms with the sausage. Can’t wait to make again.
Ann Smith
Use 2 pounds sausage hot

This has become a new family favourite. I served this at our 2019 Christmas brunch, and everyone raved about it! I will be making this many times in the years to come; in fact, I think family will come to expect it. The only ingredient substitution I made was to use regular Cheddar cheese rather than sharp, as I am not a fan of sharp cheddar, and the Monterey Jack does have a distinctive flavour of its own. In future, I may also experiment with using fresh spinach – I like the idea of finding whole spinach leaves in the casserole.

WOW, this casserole was so easy and absolutely delicious! As suggested by another, I used stuffing/dressing mix instead of the croutons. I think the seasonings in the stuffing mix took this recipe over the top. I will definitely make this again and again.
Kendra Black
Hearty and exactly what I was expecting!! My family really liked it. Had some strawberries and melon on the side to “lighten” it up. Didn’t change a thing in the recipe. A+
Jodi Leach
I will totally make it again! I made this casserole for Christmas casserole and we all loved it.
Veronica Erickson
I took it to a Ladies Brunch and everyone raved about it! Followed the recipe exactly. Will definitely make again. Thanks for the recipe!
Stephanie Kelly
No changes. Definitely will make it again.

It was delicious, and my Sunday School class liked it! I added more croutons than the recipe called for, and it turned out too “bready” for me. Next time I’ll follow the recipe more closely. I may add pimentos next time for color. I used mild sausage instead of spicy because I don’t usually like spicy hot. I used black pepper instead of cayenne for the same reason.
Ashley Davis
Delicious! Big hit with my family.

Had family in town with kids, and everyone loved it. Prepped it the night before, got up and threw it in the oven, and Voila!
