Cook macaroni according to package instructions and drain.
In a skillet, cook bacon over medium heat until crispy. Remove bacon and set aside, leaving the bacon fat in the skillet.
Add diced jalapeños to the skillet and sauté until softened, about 2 minutes.
Stir in butter and allow it to melt, then sprinkle in flour and whisk constantly for 1 minute to form a roux.
Gradually whisk in milk, ensuring there are no lumps. Cook and stir until the mixture thickens slightly, about 3-4 minutes.
Add cheddar cheese, mozzarella cheese, and parmesan cheese to the milk mixture, stirring until fully melted and smooth.
Add cooked macaroni and bacon to the cheese sauce, mixing until the pasta is fully coated.
Top with crispy onions and transfer the skillet to a preheated oven at 350°F (175°C) for 15 minutes, or until bubbly and golden brown on top.
Remove from oven and let cool for a few minutes before serving.
