1. Bring a large pot of salted water to a boil. Add penne and cook until al dente according to package directions. Drain and reserve 1/2 cup of pasta water.

2. While the pasta cooks, heat olive oil in a large skillet over medium-high heat. Toss beef with Cajun seasoning, garlic powder, onion powder, salt, and pepper. Sear beef for 2–3 minutes per side until browned and cooked through. Set aside.

3. In a small saucepan, melt butter over medium heat. Add heavy cream and bring to a gentle simmer. Stir in Velveeta Four-Cheese blend until smooth and fully melted.

4. Add drained penne and a splash of reserved pasta water to the cheese sauce. Stir to coat evenly. Fold in the Cajun beef bites and adjust seasoning if needed.

5. Serve immediately. Garnish with fresh parsley or extra cheese if desired.
