Step 1: Cook the Pasta
Bring a large pot of salted water to a boil.
Cook pasta 1 minute less than package instructions (it will finish in the sauce).
Reserve 1 cup of pasta water before draining.
Step 2: Prepare & Cook the Chicken
Flatten the chicken to an even 11.5cm thickness using a rolling pin and plastic wrap.
Season both sides with salt and black pepper, then lightly dust with flour.
Heat olive oil in a large frying pan over mediumhigh heat.
Sear the chicken for 2 minutes per side until golden brown (cook longer if thicker).
Wrap lightly in foil and set aside to rest.
Step 3: Make the Creamy Rosemary Sauce
Melt butter in the same pan over medium heat.
Sauté garlic for 1 minute (don’t let it brown).
Stir in rosemary and cook for 30 seconds.
Pour in the cream, lowering the heat to maintain a gentle simmer (do not boil).
Gradually add parmesan in 23 batches, stirring to melt each time.
Mix in black pepper and lemon juice.
Step 4: Finish the Pasta
Add ¼ cup of reserved pasta water to the sauce and let it simmer for 23 minutes.
Toss in the cooked pasta, stirring until well coated.
Let the pasta gently bubble for 12 minutes to thicken the sauce.
Step 5: Serve
Slice the chicken and serve it on top or tossed through the pasta.
Garnish with lemon zest, extra rosemary, and more parmesan.
Enjoy immediately!
