Easy Breakfast Casserole Ole

READY IN: 1hr 20mins
Recipe by Chef1MOM-Connie

I needed to make a brunch type casserole for a crowd of 8. I also did not want to have to get up to a mess so threw this recipe together to make ahead. Very simple to put together either that morning or the night before. I have done both ways now and am glad this comes out so good. Heat is up to you for taste.

I just made this a second time, and I think it was even better than the first time. <br/><br/>I was having a guest for breakfast with our family, and I halved the recipe. Even though the recipe doesn't say it, I cooked the sausage (seems a given), then I sauteed the pepper, onion, and O'Brien potatoes in the sausage grease on medium heat for about 8 minutes, and added the garlic at the end. I put the pepper, onion, potato mixture on the bottom of the pan, then put the sausage over it evenly.<br/><br/>I mixed the eggs, milk and spice in a separate bowl and put both in the fridge overnight. <br/><br/>I quickly re-mixed the egg mixture and finished the prep (I used half the butter and it was plenty!), and put it in the oven before going running and I wasn't sure if I would be back in 45... so I baked it at 300 degrees and bumped the heat up to 350 for about 15 minutes when I got back. It was PERFECT! I forgot to cook it covered, and since it worked out so well, this is how I'll bake it in the future.<br/><br/>Along with it I served fresh fruit and sticky buns.
