    Rosemary Garlic Fettuccine Alfredo with Chicken and Peas

    Am I the only one who had tons of half and half and butter left over from Thanksgiving?

    I bet not.

    I used a generous pour of half and half in my Thanksgiving mashed potatoes, but still had a few cups left over, and I pretty much always have a block of parmesan cheese in the fridge waiting to be pulsed in the food processor for freshly grated cheese.

    I spent a fortune on Thanksgiving, so I'm trying to be really resourceful in using up the extra ingredients.

    So what came to mind when I saw half and half and cheese?

    Why, fettuccine alfredo, of course!

    But you know what else also goes great with creamy cheesy sauce? Freshly minced rosemary & thinly sliced garlic, which I also happened to have on hand. YUM.

    The rosemary and garlic infuse the creamy sauce & elevates it to a higher level. Add some green peas for a pop of freshness and some tender chicken breasts for a satisfying protein, and call it a day!

    Ingredients 

    • 2 large boneless skinless chicken breasts (fresh or frozen)
    • ¾ lb dried fettuccine pasta
    • 1 stick unsalted butter (½ cup)
    • 1 tablespoon minced rosemary, divided
    • 5 cloves garlic, peeled and thinly sliced
    • 2 cups half and half
    • 1 cup freshly grated parmesan cheese, plus extra for garnish
    • Freshly cracked salt and black pepper
    • 1 heaping cup frozen peas, defrosted in the microwave

    Instructions

    • Preheat the oven to 400 degrees Fahrenheit. Place the chicken breasts (either fresh or frozen) in an 8×8 inch pyrex or ceramic baking dish. Season with freshly cracked salt & pepper, and cover the baking dish with foil.
    • Bake the chicken in the oven until an instant read thermometer inserted into the thickest part of the breast registers 165 degrees Fahrenheit. This could take anywhere from 20 to 50 minutes, depending on the size of your chicken breasts and whether your breasts were frozen or not when you put them in (it will take longer if you put them in frozen). Check them at 20 minutes, and go from there.
    • When the chicken breasts are done, remove from the oven, transfer to a cutting board, and let rest until the rest of the meal is done.
    • While the chicken is cooking, bring a large pot of salted water to a rolling boil. Add the fettuccine and cook according to package directions until al dente (usually about 10 minutes). When the pasta is done, drain and set aside.
    • As the pasta cooks, melt the butter in a large nonstick skillet over low heat, stirring constantly to prevent browning. Add the sliced garlic and ½ tablespoon of rosemary (reserving the other half for garnish) and stir until fragrant. Add the half and half & bring to a simmer. Whisk constantly with a rubber whisk for about 5 minutes, until slightly thickened. Turn off the heat and stir in the parmesan cheese. Season liberally with salt and pepper.
    • Add the pasta and peas to a large serving bowl and toss with the alfredo sauce. Slice the chicken breasts crosswise into slices. Plate the pasta and top each serving with chicken. Sprinkle with the extra minced rosemary, season with freshly cracked salt and pepper and extra cheese, if desired.

      I made this tonight and it rivals any Alfredo I've ordered at restaurants!

      Will be making this again. It's also very simple to make. Thanks 😊
