Make It Now:

  1. Preheat the oven to 350°F. Grease a 9×13 inch casserole dish or two 8×8 dishes with cooking spray.
  2. Cook the pasta according to the package instructions, until al dente (slightly undercooked). Be sure to generously salt the cooking water. When the pasta is done, drain it in a colander over the sink.
  3. While pasta is cooking, heat the oil in a large skillet over medium-high heat. When the oil is shimmery, add the bell peppers & onions and saute until they begin to soften, about 4-5 minutes. Season lightly with salt and pepper as they cook. Remove from the heat.
  4. In a large mixing bowl, gently stir together the cooked pasta with the cream of mushroom soup, chicken broth, chopped chicken, sautéed veggies, seasoned salt, cayenne, and 1 1/2 cups of the cheese. 
  5. Place the mixture in the dish (or dishes) and top with the remaining 1 cup of cheese. (Freezing instructions begin here.)
  6. Bake until bubbly around the edges, about 40-45 minutes. (If the cheese on top starts to get too dark, cover with foil.) Let cool slightly and serve warm. Taste and season with more salt and pepper as needed.

Freeze For Later: Follow steps 1-5 (do not bake). Cover the casserole dishes with a few layers of plastic wrap and foil. Squeeze out any excess air and freeze.

Prepare From Frozen: Thaw. (Here are three safe ways to thaw freezer meals.) Follow step 6. If it’s still slightly frozen in the middle, you’ll just have to cook it longer than the recipe calls for or defrost a bit in the microwave before baking. Cover it with foil if the top gets too brown in the oven.


Where We Get Our Chicken: We get our meat from ButcherBox. The chicken is organic and curated from small, trusted farms. We highly recommend this service to source healthy meat–like uncured bacon, wild salmon, and grass-fed beef–and have used it for years ourselves.
