Start by seasoning the chicken breasts with salt and pepper. In a large pot, melt the light butter over medium heat until it is bubbly. Cook the chicken for about 6 to 8 minutes on each side until it is golden brown and no longer pink inside. Keep an eye on it to avoid dryness.
Once the chicken is cooked, toss in the minced garlic and stir for 1 minute until you smell that aromatic goodness. Then pour in the chicken broth, scraping up any tasty bits from the bottom of the pot. Let it simmer for a bit before moving on.
Add the pasta right into that broth. Give it a good stir to coat every piece. The pasta should start to soften and absorb the flavors. Stir occasionally to prevent sticking.
While the pasta cooks, whisk together the almond or skim milk with the cornstarch in a bowl until smooth. This gives your sauce a creamy texture without extra calories.
Once the pasta is al dente and has soaked up a lot of the broth, stir in the milk mixture. Continue cooking for a few more minutes until everything is heated through and the sauce thickens nicely.
Remove the pot from heat and sprinkle the fresh grated Parmesan cheese into the mixture. Stir until melted for a creamy sauce. Taste before adding more salt, as the cheese adds flavor too.
Dish up the Lightened Up Alfredo and sprinkle with fresh parsley and crispy bacon crumbles, if desired. Serve hot for the best experience.
