The sharp cheddar is my secret favorite for this recipe because it gives each bite a bold tang that stands up to the spicy jalapeños. My kids love helping to sprinkle the bacon on top before baking and the kitchen always fills with the best cheesy aroma.
Storage Tips
Let your cheese squares cool completely before covering the dish with foil or plastic wrap and storing in the fridge. They keep well for three days and reheat gently in the oven to restore crisp edges. If you plan to freeze cool first cut into squares and wrap well in layers of parchment then tuck in a zip top bag. Thaw overnight in the fridge and warm up in the oven for best texture.
Ingredient Substitutions
Feel free to swap Monterey Jack for mozzarella for a milder flavor or use pepper jack if you want extra spice. Turkey bacon or a vegetarian bacon substitute adds similar smokiness for non pork eaters. For a gluten free version simply use a good quality gluten free flour. A handful of fresh jalapeños adds even more kick if you have them on hand.
Serving Suggestions
These squares pair beautifully with a crisp salad or a big bowl of tomato soup for a simple lunch. For party spreads set out a platter with salsa sour cream and sliced radishes. Try making them slightly smaller for bite sized appetizer portions or even add them to brunch with eggs and fruit on the side.
