Ingredients

1 (22 ounce) jar Alfredo sauce (or 1 ½ 15-ounce jars) (approximately 2 ½ cups total)
3 cups chicken broth
¼ cup white wine (or sub with additional chicken broth or water)
¼ cup prepared basil pesto
2 teaspoons Italian seasoning
½ teaspoon crushed red pepper flakes (use less, or omit entirely if you don’t like it spicy)
½ teaspoon garlic powder
¼ teaspoon onion powder
2 cups diced rotisserie chicken (or other diced cooked chicken)
1 (16 ounce) package uncooked mezzi rigatoni pasta (or other similar short pasta shape such as rotini or penne)
1 (14.5 ounce) can petite diced tomatoes, well drained
2 cups fresh baby spinach leaves, coarsely chopped
1 cup shredded Italian cheese blend or mozzarella cheese
Optional: Parmesan cheese and fresh chopped herbs such as basil, oregano, and parsley for garnish

Instructions

Preheat oven to 425°F. Grease a 13 x 9-inch baking dish or spray with nonstick cooking spray. In the prepared baking dish (or in a separate large bowl), whisk together the Alfredo sauce, broth, wine, pesto, Italian seasoning, red pepper flakes, garlic powder, and onion powder. Stir in the chicken, uncooked pasta, and diced tomatoes. Cover tightly with aluminum foil and bake for 40 minutes.
Uncover; stir gently with a fork. At this point you should check the pasta to make sure that it is al dente (firm but just about finished cooking). If it’s still too hard, cover the dish and return to the oven until pasta is al dente. Then move on to the next step.
Stir the spinach into the pasta. Sprinkle the cheese over the top. Place the dish under the broiler for 1-2 minutes, just until the cheese melts and starts to get crispy on top. Watch the dish the entire time since the food can burn quickly under the broiler! Garnish with chopped fresh herbs and serve.

Notes

Total cooking time will vary depending on the type of pan that you use, your brand of pasta, and your individual oven. Glass or ceramic baking dishes will take longer than metal pans, for instance. To know when your casserole is done, taste a bite of the pasta. The noodles should be tender and much of the liquid should be absorbed.

You’ll need at least one large 22-ounce jar of Alfredo sauce. If you can’t find this larger size jar in your store, purchase two smaller (15 ounce) jars and measure out about 2 ½ cups of sauce total. One smaller jar won’t be quite enough.

Don’t have mezzi rigatoni? You can substitute with other similar short pasta shapes such as penne, rotini, or elbows. Just pick a pasta that has a similar cooking time as the mezzi rigatoni (about 8-10 minutes recommended on the package) — otherwise you’ll need to adjust the casserole’s baking time in the oven.
