Recipe Overview

Step-by-Step Instructions

The process of creating this dish is straightforward and rewarding, focusing on layering flavors and allowing time for the magic to happen in the refrigerator.

Step 1: Preparation

1. ○Preheat your oven to 350°F (175°C) so it is ready for the baking process. Grease a 9×13 inch baking dish generously with butter until the surface feels slick and smooth to the touch.
2. ○Spread the cubed bread evenly across the base of the dish. The bread should feel slightly dry and firm, as this texture is ideal for soaking up the custard without losing its structure.
3. ○In a large mixing bowl, whisk together the milk, eggs, heavy cream, dry mustard, salt, and black pepper. Continue whisking until the mixture is uniformly yellow and frothy, with a smooth, consistent liquid texture.

Step 2: Assembling the Layers

1. ○Pour the prepared egg mixture evenly over the bread cubes in the baking dish. Use a spatula to press down gently, ensuring every piece of bread is submerged and feels spongy as it begins to absorb the liquid.
2. ○Scatter the diced turkey and crumbled turkey bacon over the top of the bread. Ensure the meat is evenly distributed, creating a consistent savory flavor profile throughout the dish.
3. ○Finish by sprinkling the shredded cheddar cheese over the surface. The cheese should form a uniform, beautiful layer that will melt into a golden crust during baking.

Step 3: Overnight Resting

1. ○Cover the dish tightly with aluminum foil to protect the ingredients. Place the dish in the refrigerator for at least 8 hours, allowing the bread to fully soak up the custard and develop deep, complex flavors.
2. ○On the morning of, remove the dish from the refrigerator. Let it sit at room temperature for 30 minutes so it feels cool but not ice-cold before going into the oven.
3. ○Ensure your oven is still preheated to 350°F (175°C) while the casserole rests. This gentle transition helps the ingredients bake evenly throughout the entire dish.

Step 4: Baking and Serving

1. ○Bake the casserole covered with foil for 30 minutes. This traps heat to cook the center of the dish thoroughly.
2. ○Remove the foil and bake for another 20-25 minutes until the top is golden brown and puffed. The aroma will be warm and savory, filling your home with holiday cheer.
3. ○Check that the casserole is set in the center and jiggles slightly. A knife inserted near the middle should come out clean. Let it rest for 5 minutes before garnishing with fresh green onions and slicing.

Frequently Asked Questions

Can I use a different type of bread?

Yes, you can absolutely use different types of bread such as sourdough, brioche, or whole wheat. Sourdough adds a nice tang, while brioche provides a softer, richer texture to the final dish. Just ensure the bread is cubed and slightly dry so it absorbs the custard without becoming overly soggy.

Why is it important to use day-old bread?

Using day-old or slightly stale bread is crucial because it has less moisture content than fresh bread. This allows the bread to act like a sponge, soaking up the egg and cream mixture without breaking down into a mushy consistency. It ensures that the casserole maintains a beautiful structure when you slice and serve it.

Do I really need to refrigerate it for 8 hours?

While you can bake it sooner, the 8-hour rest period is highly recommended for the best results. This long soak allows the custard to fully penetrate each cube of bread, ensuring a consistent texture throughout. It also allows the flavors of the mustard, salt, and pepper to meld perfectly with the protein.

Can I add vegetables to this recipe?

Absolutely, adding vegetables is a great way to customize this casserole to your liking. You can incorporate sautéed spinach, mushrooms, bell peppers, or onions. Just make sure to sauté them beforehand to remove excess moisture, as this prevents the casserole from becoming watery during the baking process.

How do I know when the casserole is fully cooked?

The casserole is done when the top is golden brown and the center is set. You can check this by giving the dish a gentle shake; it should jiggle slightly but not appear liquidy. Additionally, a knife inserted near the center should come out clean, indicating that the custard has fully set.
