I have been trying all sorts of breakfast casseroles to pick just the right one to fix for Christmas morning. Since we always have my homemade sausage bread (an old secret family recipe) this Mexican Cheese Puff casserole, sans meat, seemed like the perfect main dish. And if you love Mexican food, this casserole has exactly what you’re looking for! The flavors of salsa, cheese and heat are definitely reminiscent of south of the border and, if you like your Mexican a little milder, just use regular Monterey Jack instead of the Jalapeno version.

This dish surprised my husband a little because I just packed it up for him to bring to work without telling him what it was. He took one bite and called to say how much he loved it! Of course our house is crazy about Mexican so it was a safe bet that he would enjoy it.

Need gluten-free? Just substitute an all-purpose gluten-free flour for the regular flour and you are good to go. Since we’ll be spending the holidays with my daughter, who is gluten intolerant, this will please one and all.

Oh, and just a quick note, you can also serve this as a side to any Mexican meal, such as Carne Asada.

If you are in a hurry on Christmas morn, you can make up the cheese mixture ahead of time and store in the refrigerator in the bottom of the prepared pan (less dishes – yay!)
