  • Measuring Cups
  • Measuring spoons
  • Knife
  • Cutting board
  • Colander

Ingredients
  

Pasta

  • 12 oz linguine or spaghetti Your favorite long pasta works perfectly here.

Chicken and Vegetables

  • 4 cups rotisserie chicken, shredded or diced This is your secret weapon for speed and flavor! Or, use about 1.5 lbs of chicken breast, cooked and shredded.
  • 2 Tbsp olive oil For sautéing our veggies.
  • 1 lb button mushrooms, thickly sliced Mushrooms add such a wonderful earthy depth.
  • 1 medium onion, finely chopped The flavor base for our creamy sauce.
  • 4 cloves garlic, minced Because garlic makes everything better, right?

Creamy Sauce Base

  • 4 Tbsp unsalted butter The start of our luscious sauce.
  • 0.33 cup all-purpose flour This will help thicken our sauce to creamy perfection.
  • 3 cups low-sodium chicken broth Adds body and savory notes to the sauce.
  • 1 Tbsp lemon juice A little brightness to cut through the richness.
  • 2 cups half & half This is key for that luxurious, velvety texture. (If you don't have it, equal parts milk and heavy cream work great too!)
  • 1.5 tsp sea salt, plus more to taste Always important to season as you go!
  • 0.25 tsp black pepper, freshly ground For a little kick.

Finishing Touches

  • 0.25 cup parsley, chopped, plus more for garnish Fresh parsley adds a pop of color and freshness.
  • 1.5 cups shredded mozzarella cheese For that irresistible cheesy pull.

Instructions
 

  • Cook the pasta according to the package directions. While that's bubbling away, let's get started on the sauce. Drain the pasta when it's done and set it aside – don't rinse it!

  • In a large skillet or Dutch oven over medium-high heat, add your olive oil. Once it's shimmering, toss in your sliced mushrooms. Let them cook, stirring occasionally, until they're beautifully browned and have released their moisture, about 5-7 minutes. Then, scoop them out and set them aside with your cooked pasta.

  • In that same skillet (no need to wash it!), add your chopped onion. Cook it until it's nice and soft, about 5 minutes. Then, add your minced garlic and cook for just one more minute until it smells amazing and fragrant.

  • Add the butter to the skillet and let it melt. Once it’s melted, sprinkle in the flour. Whisk it together with the butter for about a minute, stirring constantly. This is called a "roux," and it's the magic behind our thick, creamy sauce!

  • Slowly, and I mean slowly, whisk in the chicken broth. Keep whisking as you pour to make sure there are no lumps. Bring this mixture to a simmer and keep stirring until it starts to thicken up nicely.

  • Now for the luxurious part! Stir in the lemon juice, half & half, salt, and pepper. Let it gently simmer for another 2-3 minutes, just until everything is heated through and the sauce is wonderfully smooth.
