Cook the shell pasta according to package directions until al dente. Drain well and set aside.

While the pasta cooks, season the cubed sirloin steak generously with fajita seasoning.

Heat olive oil in a large skillet over medium-high heat. Add the seasoned steak and cook, stirring occasionally, until browned and cooked through, about 5 to 7 minutes. Remove the steak from the skillet and set aside.

In the same skillet, add the sliced bell pepper and yellow onion. Sauté until softened and slightly caramelized, about 5 to 7 minutes. Remove from the skillet and set aside with the steak.

In a large saucepan or Dutch oven, melt the unsalted butter over medium heat. Whisk in the all-purpose flour and cook for 1 minute, stirring constantly, to create a roux.

Gradually whisk in the whole milk until smooth. Bring the mixture to a gentle simmer, stirring constantly, until the sauce thickens, about 3 to 5 minutes.

Reduce the heat to low. Stir in the softened cream cheese until it is completely melted and smooth. Add the shredded sharp cheddar cheese, Monterey Jack cheese, and grated Parmesan cheese, stirring until all the cheeses are fully melted and the sauce is creamy. Season with kosher salt, freshly ground black pepper, and cayenne pepper (if using).

Add the cooked pasta, cooked steak, and sautéed bell peppers and onions to the cheese sauce. Stir gently to combine all ingredients thoroughly, ensuring the pasta and steak are well coated in the creamy sauce.

Serve the Fajita Steak Mac n Cheese hot, garnished with fresh chopped cilantro.
