Instructions

Cook sausage mixture: On the stovetop, cook and crumble the breakfast sausage in a large skillet over medium-high heat until browned, about 8-10 minutes. Add the diced onion and cook until translucent, 3-4 minutes. Stir in the chopped green chilies and cook for an additional 1 minute. Remove from heat.
Prepare English muffins: Tear the English muffins into bite-sized pieces, approximately 1 inch in size.
Assemble casserole layers: Grease a 9×13-inch baking dish. Evenly layer half of the torn English muffin pieces at the bottom, then half of the sausage mixture, followed by half of the shredded cheese. Repeat these layers once more.
Mix egg and salsa: In a separate bowl, beat together the eggs, milk, and salsa until well combined. Pour this mixture evenly over the assembled layers in the baking dish.
Refrigerate overnight: Cover the dish tightly with aluminum foil and refrigerate overnight to allow the flavors to meld and the bread to absorb the egg mixture thoroughly.
Preheat oven and prepare to bake: Remove the casserole from the refrigerator 45 minutes to 1 hour before baking to come to room temperature. Preheat oven to 350°F (175°C).
Bake casserole: Keep the casserole covered with foil and bake in the preheated oven for 60 minutes. Then uncover and bake for an additional 10 to 15 minutes until the eggs are set and the cheese is melted and bubbly. Let the casserole rest for 5-10 minutes before serving.

Notes

For added flavor, you can sprinkle fresh cilantro on top before serving.
Feel free to substitute the breakfast sausage with turkey sausage for a leaner option.
Use your favorite salsa variety – mild, medium, or hot – depending on your spice preference.
This casserole can be assembled and frozen before baking; just thaw overnight in the refrigerator before baking.
Letting the casserole rest before cutting helps it set for cleaner slices.
