Step-by-Step Instructions
Step 1: Prepare Your Beef Foundation
-
Heat a large skillet over medium-high heat and brown the ground beef thoroughly, breaking it into small, uniform pieces. Season generously with salt and pepper while cooking. This process should take 8-10 minutes, ensuring no pink remains visible. Drain excess fat but reserve 2 tablespoons for added flavor depth. The key here is achieving a golden-brown color that will contribute rich, savory notes throughout your breakfast casserole.
Step 2: Sauté the Aromatic Vegetables
-
Using the same skillet with reserved beef drippings, add diced onions and bell peppers. Cook for 5-6 minutes until softened and fragrant. Add minced garlic during the final minute to prevent burning. This technique builds layers of flavor that will permeate every bite of your finished dish.
Step 3: Create the Egg Custard Base
-
In a large mixing bowl, whisk together eggs, milk, and softened cream cheese until completely smooth. Season this mixture with salt, pepper, and dried herbs. The cream cheese addition is a professional secret that creates an incredibly creamy texture that sets your breakfast casserole apart from ordinary versions.
Step 4: Assemble the Foundation Layer
-
Generously butter a 9x13 inch baking dish. Arrange bread cubes evenly across the bottom, creating a sturdy foundation. Distribute the cooked beef and vegetable mixture over the bread, followed by fresh spinach leaves and half of the grated cheese.
Step 5: Unite All Components
-
Pour the egg custard mixture slowly over the assembled ingredients, ensuring even distribution. Gently press down with a spatula to help the bread absorb the liquid. Top with remaining cheese and chopped bacon pieces for a beautiful golden finish.
Step 6: The Perfect Bake
-
Preheat your oven to 350°F and bake the breakfast casserole for 45-50 minutes. The center should be set but slightly jiggly when gently shaken. The top will develop a gorgeous golden-brown color that signals doneness.
