This sounds absolutely divine, but I was wondering where you get the mustard powder, or can you use something else instead? My husband is not a fan of mustard, but he really loves his mayo. I think this would be great for all of us because we like to eat a lot for brunch instead of eating two meals on the weekends. That way we can sleep in.

Hi SissieSass, dry mustard can usually be found in the spice aisle. However, if you're not crazy about the mustard flavor, I think leaving it out would be fine. - Natalie, Editor of AllFreeSlowCookerRecipes

Hubby and I don't do much cooking especially on the weekends but sometimes want a home cooked breakfast meal. This is an awesome breakfast meal without standing over a hot stove. I will definitely make this recipe next weekend. My hubby will be surprised to have such a delicious breakfast before he goes to work.

A MUST make for this Christmas brunch with my large crew of family! Huge bonus that it's make-ahead slow cooker!!

I will indeed be making this for Christmas morning. I made it for Thanksgiving and it was a big hit!

This looks great, but I have a lot of 'make ahead breakfast casserole' recipes saved that I haven't tried yet. I like that this one adds hot sauce and hot sausage.

I would try this without the pork. Maybe substitute with turkey )

I like home fries w/sauted onions, eggs, biscuit sausage gravy. The casserole looks like a winner also!

I love easy breakfasts when there's company. This is very similar to one I make, and our friends and family absolutely love it! (We use diced, partially cooked potatoes instead of bread.) My first crock pot was a Hamilton - I bought a new one last year when my husband accidentally dropped the liner and broke it (after 34 years - no, really - 34 years!)

Cinnamon rolls and Cajun Coffee

This would be great to make ahead to serve on Christmas morning.
