Creating One-Skillet Buffalo Ranch Steak & Pasta is straightforward. Follow these steps for a delicious meal:

1. Cook the Pasta: In a large skillet, bring salted water to a boil. Add the pasta and cook according to package instructions until al dente. Drain and set aside.
2. Sauté the Vegetables: In the same skillet, heat olive oil over medium heat. Add sliced bell peppers and onions, cooking until softened, about 5 minutes. Stir in minced garlic and cook for an additional minute.
3. Cook the Steak: Push the vegetables to the side of the skillet. Add the sliced steak to the skillet, seasoning with salt and black pepper. Cook until browned, about 3-4 minutes.
4. Combine Ingredients: Once the steak is cooked, reduce heat to low. Stir in the buffalo sauce, ranch dressing, and cooked pasta. Mix until everything is well coated.
5. Add Cheese: Sprinkle the shredded cheese over the top. Cover the skillet and let it sit for 2-3 minutes until the cheese melts.
6. Garnish and Serve: Remove the skillet from heat. Garnish with chopped green onions before serving.
