Step 1: Preheat the Oven Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or cooking spray to ensure easy removal of the casserole after baking.

Step 2: Whisk the Egg Mixture In a large mixing bowl, whisk together the eggs, milk, and heavy cream until fully combined. Add the ranch seasoning mix, garlic powder, onion powder, smoked paprika, salt, and pepper. Stir well to incorporate the seasonings.

Step 3: Layer the Ingredients Spread the thawed hash browns evenly across the bottom of the prepared baking dish. Sprinkle the crumbled bacon and shredded cheddar cheese evenly over the hash browns. Add the chopped green onions if desired.

Step 4: Pour the Egg Mixture Slowly pour the egg mixture over the layered ingredients, ensuring it evenly covers the hash browns, cheese, and bacon.

Step 5: Bake the Casserole Place the baking dish in the preheated oven and bake for 45–50 minutes, or until the eggs are set and the top is golden brown. Check for doneness by inserting a knife into the center—it should come out clean.

Step 6: Cool and Serve Allow the casserole to cool for 5–10 minutes before slicing and serving. Garnish with additional green onions or a dollop of sour cream if desired.
