I love alfredo sauce. Especially my homemade sauce. But it’s even better when I can use it in a variety of ways to make new meals. This was a meal that we came up with during the COVID19 pandemic. We were trying to limit visits to grocery stores which meant a lot of “pantry week” meals.

One of those times, I was looking at all the food we had. What needed to be used first? We almost always have some chicken in the freezer. And there was spinach in the refrigerator that was going to go bad soon. I tend to have half-full boxes of pasta in the pantry a lot. The boys don’t eat a lot of pasta, so it leaves me with bits here and there.

So, put all that together with some of the cheese we had and we have the ingredients for chicken and spinach alfredo! I decided it needed to be in a casserole to make it easier. Plus, there was a lot of it.

Step by Step

Preheat the oven to 400F. In a large saucepan, bring the water to a boil and add the pasta. Cook for about 6 minutes then add the spinach.

Cook for 2 minutes, until the spinach is wilted. Drain and place the pasta and spinach mixture in a large mixing bowl.

Meanwhile, heat the oil in a large skillet over medium-high heat. Cut the chicken into bite-sized pieces and sprinkle with the salt and pepper then add to the pan. Cook for about 8 minutes. Or until the chicken is cooked through.

Leftovers

Cover any leftover chicken and spinach alfredo bake in the casserole dish or move to a container. Refrigerate for up to 3-4 days. To reheat, place back in the oven for about 5 minutes, until heated through. Or you can add a small amount of milk and warm it in a saucepan over medium heat.
