Method
- Cook pasta in heavily salted boiling water for 1 to 2 minutes under package directions. Drain and reserve ½ cup pasta water. Set aside.
- Heat olive oil in a large skillet over medium-high heat. Season steak cubes with salt, pepper, and smoked paprika. Sear in a single layer for 3 to 4 minutes until browned on all sides, aiming for medium-rare. Remove to a plate and tent with foil.
- Reduce heat to medium. Add butter to the same skillet with the drippings. Once melted, whisk in flour and cook for 1 to 2 minutes until golden and nutty-smelling.
- Add milk in a slow, steady stream while whisking constantly. Simmer over medium heat for 5 to 7 minutes, whisking frequently, until sauce thickens to coat the back of a spoon.
- Reduce heat to low. Add garlic powder and cayenne. Add shredded pepper jack and white cheddar in 2 to 3 small additions, stirring fully between each until the sauce is smooth. Fold in drained diced tomatoes and green chiles.
- Add drained pasta to the sauce and stir gently to coat. Add seared steak cubes with any accumulated plate juices and fold together.
- Cook over low heat for 1 to 2 minutes until piping hot. Add reserved pasta water a tablespoon at a time if sauce is too thick.
- Divide into bowls and garnish with fresh cilantro or green onions and red pepper flakes.
Notes
Storage: Refrigerate in an airtight container for up to 3 days. Add a splash of milk when reheating and warm over medium-low heat stirring frequently. Do not use pre-shredded cheese as it causes a grainy sauce. Add cheese in small additions over low heat for the smoothest result. Ground beef, spicy sausage, or chorizo can substitute for steak. For a milder version, replace pepper jack with Monterey Jack. For a baked version, top with extra cheese and breadcrumbs and broil at 425°F for 8 to 10 minutes.
