In a large pot, bring salted water to a boil. Add the uncooked pasta and cook according to package instructions until al dente. In the last 3 minutes of cooking, add the broccoli florets to the pot. Drain and set aside.
In a large skillet, heat the olive oil over medium heat. Add the diced chicken and season with garlic powder, onion powder, salt, and pepper. Cook for about 5-7 minutes until the chicken is cooked through and no longer pink.
In the skillet with the cooked chicken, add the drained pasta and broccoli. Pour in the ranch dressing and half of the shredded cheddar cheese. Stir well to combine all the ingredients.
Lower the heat and sprinkle the remaining cheddar cheese on top. Cover the skillet with a lid and let it sit for 2-3 minutes until the cheese is melted and bubbly.
Once the cheese has melted, remove the lid and give everything a gentle stir. Taste and adjust seasoning if necessary.
Serve the cheesy ranch chicken broccoli pasta warm, garnished with chopped fresh parsley for a pop of color.
Notes
Feel free to add more vegetables or adjust the cheese to your liking.
