Typed recipe card for macaroni cheese casserole
Macaroni and cheese casserole is a comforting staple in American cuisine, beloved for its creamy texture and cheesy flavor. Originating from European pasta and cheese dishes, it became popular in the U.S. thanks in part to Thomas Jefferson, who encountered it in France and brought the concept home. This particular version, featuring green pepper, dry mustard, pimiento, and a blend of sharp cheddar, adds a Southern twist. Baked to golden perfection, it embodies the hearty, family-style meals that are central to American comfort food traditions. Ideal for weeknight dinners, potlucks, and holidays, it’s a warm, nostalgic dish that continues to bring people together.
