Start by browning the turkey sausage in a skillet over medium-high heat, breaking it apart as it cooks for 8-10 minutes until fully cooked and no pink remains. While the sausage cooks, dice the bell pepper and red bell pepper into ½-inch pieces, mince the garlic (if using fresh instead of powder), slice the green onions, and chop the cilantro. Drain the excess fat from the cooked sausage and set aside. Having all your prep work done before assembly ensures smooth operation once you start layering the casserole.

Spray your crockpot with cooking spray to prevent sticking. Layer the slightly thawed hash browns on the bottom, breaking up any large clumps to distribute evenly. Scatter the browned sausage from Step 1 over the hash browns, then add the diced bell peppers. Sprinkle the cumin, garlic powder, chipotle powder, and season with sea salt and black pepper to taste. I like to taste the dry mix by pinching a tiny bit—this helps you nail the seasoning before the eggs go in, which is harder to adjust later.

In a bowl, whisk together the 8 large eggs with ½ cup water until well combined and no streaks of yolk remain. Pour this mixture evenly over the casserole base from Step 2, making sure the liquid distributes throughout and reaches into the crevices. Top with both shredded cheddar and Monterey Jack cheese, distributing evenly across the surface. I recommend using the full amount of both cheeses—the combination creates a richer, more complex flavor than using just one.

Cover the crockpot and cook on low heat for 4-6 hours. The casserole is done when the eggs are fully set and no longer jiggle in the center when you gently shake the pot—it should feel firm but still moist. Cooking times vary depending on your specific crockpot, so start checking around the 4-hour mark.

Turn off the crockpot and let the casserole rest for 5 minutes before serving. Spoon portions onto plates and top with fresh cilantro, sliced green onions, a dollop of sour cream, and additional shredded cheese if desired. The fresh toppings add brightness and texture that contrast beautifully with the warm, creamy casserole.
