Make the most of your prime rib leftovers with this easy, creamy Prime Rib Quiche! Tender beef, melty cheese, and a buttery crust make the perfect brunch.
Use a fork to poke holes in the bottom of the crust to release steam while baking. Bake for 10 minutes in preheated oven.
In a large mixing bowl, add the eggs, heavy cream, mustard, Worcestershire sauce, salt, and pepper, and whisk to combine. Mixture will be slightly frothy. Set aside.
Evenly distribute the prime rib, cheese, and chopped onions to the bottom of the pie shell. Carefully pour the egg mixture over the top, making sure not to overfill. Tent with foil and bake for 30 minutes.
Remove foil, bake another 45-55 minutes. Quiche is finished baking when there is only a slight jiggle in the middle. Remove from oven and let cool for 15 minutes so the quiche sets.
Top with green onions, if desired, slice, and serve.
Notes
Note 1 - You can use a total of 2 cups of any meltable cheese, such as cheddar, Monterey Jack, Pepper jack, mozzarella, or havarti.
