First, pre-heat your oven to 400 degrees.
Second, place the chicken breasts on a sheet pan sprayed lightly with olive oil cooking spray.
Next, scatter the potatoes as evenly as possible onto the sheet pan.
Then, smother the chicken and potatoes with half of the butter using a brush.
After that, you will want to sprinkle the chicken and potatoes with salt & pepper to taste.
Next, place the sheet pan in the oven and bake for 45 minutes.
When your timer beeps, use potholders to remove the sheet pan from the oven.
Then, place the asparagus onto the sheet pan with the chicken and potatoes.
After that, you will want to smother the asparagus in the rest of the butter and sprinkle the Italian dressing seasoning all over everything on the sheet pan.
Lastly, place the sheet pan back into the oven for another 8-10 minutes.
Serve & enjoy!
