Crockpot Breakfast Casserole

Instructions

1. For easy cleanup, line a 6-quart slow cooker with a disposable slow cooker liner and coat the liner with nonstick spray.
2. In a large cast-iron skillet or similar large, thick-bottomed pan, cook the bacon over medium-low heat, until the fat has rendered and the bacon pieces are crisp, about 10 minutes. (Resist the temptation to rush it, or the bacon will burn.) With a slotted spoon, remove the bacon to a paper-towel-lined plate. Discard all but 1 tablespoon of bacon fat from the skillet.
3. Return the pan to the stove and heat over medium. Add the bell pepper and shallot. Sauté until the pepper is softened, about 6 minutes. Remove from the heat.
4. In a large bowl, whisk the eggs, milk, mustard, salt, black pepper, and cayenne until the whites and yolks are completely incorporated and the eggs are slightly foamy.
5. To assemble the casserole, arrange the bread cubes in the bottom of the slow cooker in an even layer. Top with half of the bell pepper mixture, then half of the spinach (break up any clumps to scatter it over the top), artichoke hearts, and fontina. Repeat with the remaining bell peppers, spinach, artichoke hearts, and fontina. Top with the feta.
6. Carefully pour the egg mixture over the top. If needed, use the back of a large spoon to push down the bread and cheese so that they are mostly submerged in the liquid. Sprinkle the bacon on top.
7. Cook on LOW for 7 to 8 hours, or until the eggs are set. Remove the casserole (still in the liner) from the slow cooker and transfer it to a large plate. Let cool in the liner for 10 minutes, then carefully remove the liner. Slice and serve.
