So there's a first time for everything, and since this weekend turned out to be a pretty cold and windy one, this recipe was a welcomed surprise (and addition to my recipe collection).
2 lbs ground sirloin
4 slices bacon, diced
1/2 medium onion
1 pkg mushrooms, sliced
4 large potatoes
1 pkg blue cheese, crumbled
chives, diced - divided
1 egg yolk, slightly beatened
Brown bacon in a skillet with 2 tbsp olive oil, drain bacon pieces on paper towel. Add sirloin to bacon grease and brown up, seasoning with salt and pepper. Add onions and mushrooms, 1/2 way through cooking. Drain.
Meantime peel and boil potatoes until soft. Mash potatoes, add 1/4 c sour cream, chives and blue cheese to potatoes. Add egg yolk. Combine thoroughly.
In a casserole dish, layer the sirloin mixture at the bottom of the pan (spreading to all sides). Repeat this process with potatoes.
Brown the top of the dish in your oven (preheated to 375), uncovered for about 5-10 minutes - the egg will help the potatoes to brown.
Top with remaining chives and bacon pieces.
