Kitchen Tip:  The Hot Spot on your Slow Cooker
Every slow cooker seems to have a hot spot in it.  It is usually on the side opposite of the controls, or somewhere on the back part.  From now on notice where food sticks on and gets crusty.  Then use a foil collar to prevent burning and sticking.  I like to use foil collars when I make a casserole-type recipe in the slow cooker; it ensures that the casserole will cook evenly. 
Here is how to make a foil collar:
Layer and fold sheets of heavy duty foil until you have a six-layered foil rectangle.  Press the collar into the back side of your slow cooker insert (or wherever your hot spot is); the food will help hold the collar in place during cooking.

I served this hearty breakfast casserole for dinner.  It hit the spot...there were so many layers and delicious ingredients.  This would be great for a brunch or Christmas morning or as I served it--for dinner.  Feel free to add in whatever veggies you want.  3 1/2 stars


  1. Sounds delicious! And easy if you have company and it's hectic.

  2. It doesn't look like this comes up very far in your crockpot. Do you think I could I double or at least 1 and 1/2x it and still have it cook through?

  3. I bet you could 1 1/2 times it no problem! I don't know about doubling it though.

  4. I'm gonna surprise the folks with this tomorrow. Such simple ingredients yet looks absolutely delicious. I wish I had the knack for putting these combos together to make something great. Thanks

  5. You just gotta love an easy recipe. Prepared this last night for a family get-together and they absolutely loved it. Another hit for me. Thanks for the wonderful recipe.

  6. I have massacred your beautiful dish on my first try. I made it right after reading your recipe and needed to substitute for what I have on hand. Had to use frozen bag hash browns, a piece of beef smoked sausage cut up & browned, fresh onions & green bell peppers, no fresh spinach - thought I had a box of frozen but it turned out to be chopped broccoli and too old to use anyway. I only had 4 eggs, so reduced recipe by eyeballing. It ended up being baked, as I didn't have the 2 hrs. to do in the crock pot, at 350 for 45 minutes. Thank you for the lovely pictures and meal idea. My variation was delicious. I'll try yours next.
