Preheat oven to 425°. Cook macaroni according to package directions; drain.
Meanwhile, sprinkle ¼ cup bread crumbs into 36 greased mini-muffin cups. In a large saucepan, melt butter over medium heat. Stir in flour and seasonings until smooth; gradually whisk in milk. Bring to a boil, stirring constantly; cook and stir until thickened, 1-2 minutes. Stir in 1 cup cheddar cheese and Swiss cheese until melted.
Remove from heat; stir in biscuit mix, eggs and ½ cup bread crumbs. Add macaroni; toss to coat. Spoon about 2 tablespoons macaroni mixture into each prepared mini-muffin cups; sprinkle with remaining cheddar cheese and seasoned bread crumbs.
Bake until golden brown, 8-10 minutes. Cool in pans 5 minutes before serving.
