Step 1: Cook the pasta
Boil a large pot of salted water.
Cook pasta to al dente (1 minute less than package).
Reserve ½ cup pasta water, then drain.
Step 2: Sear the chicken
Pat chicken dry.
Season with salt, pepper, and Italian seasoning.
Heat 1–2 tbsp olive oil in a large skillet over medium-high.
Add chicken in one layer; cook 4–6 minutes, stirring once, till browned and cooked through.
Transfer chicken to a plate; leave browned bits in the pan.
Step 3: Make the garlic-parm sauce
Turn heat to medium.
Add a touch more oil if the pan is dry.
Add minced garlic and cook 30–45 seconds till fragrant.
Pour in chicken broth and milk, scraping up the browned bits.
Simmer 2–3 minutes so it slightly thickens.
Sprinkle in parmesan a little at a time, whisking so it melts smoothly.
Step 4: Make it “healthy creamy”
Take the skillet off the heat.
Stir in 2–3 tbsp Greek yogurt — off the heat so it doesn’t curdle.
Add lemon juice, taste, and adjust salt and pepper.
Step 5: Bring everything together
Add the cooked pasta and the cooked chicken to the skillet.
Toss until everything is coated in sauce.
If it’s too thick, add a splash of pasta water.
Add spinach or broccoli now and let the heat wilt/cook it.
Sprinkle parsley and a bit more parmesan on top.
