Chicken

Heat 1 tablespoon butter and 2 tablespoons olive oil in a large skillet over medium-high heat
Season both sides of each chicken breast with seasoned salt and a pinch of pepper
Add the chicken to the skillet and cook 5–7 minutes per side until cooked through
Bring a large pot of water to a boil, season with kosher salt, add the pasta, and cook until al dente; reserve 1/2 cup pasta water and drain
Remove the chicken from the pan and transfer to a cutting board to rest
Turn heat to medium and add the remaining 1 tablespoon butter and 1 tablespoon olive oil to the pan
Add squash, broccoli, mushrooms, red pepper, onion, and red pepper flakes and stir to coat; cook until veggies are tender, about 5 minutes
Add the garlic and a generous pinch of salt and pepper and cook 1 minute
Deglaze the pan with the white wine and cook until reduced by half, about 3 minutes
Stir in the milk and heavy cream, bring to a gentle boil, and simmer 2–3 minutes
Turn off the heat and add the Parmesan cheese and cooked pasta, then season with salt and pepper to taste
Garnish with additional Parmesan and chopped parsley if desired
