Preheat the oven to 350°F. Start by melting the unsalted butter and pouring it into the bottom of a 9x13 baking pan, ensuring a rich flavor and a crispy base for your chilaquiles.

Whisk together the large eggs, kosher salt, coarse ground black pepper, and whole milk in a large bowl. This creates a fluffy, creamy mixture that will form the base of your dish.

Pour the egg mixture carefully into the buttered baking pan. Place it in the oven and bake uncovered for 12-15 minutes, just until it begins to firm up around the edges.

Stir gently. After the initial bake, take it out and give the mixture a light stir. This helps to ensure even cooking throughout.

Layer the tortilla chips evenly over the partially baked eggs, following with fresh salsa and then the generous sprinkling of cheddar cheese on top.

Bake for an additional 15 minutes, or until the eggs are fully set and the cheese is beautifully melted and bubbly. The aroma will be irresistible!
