What Makes This Leftover Turkey Casserole Healthy

This recipe builds its creamy, savory flavor from a base of sautéed vegetables, unsalted broth, and low-fat milk, creating a rich sauce without relying on high-sodium canned cream soups. By using nutrient-dense chickpea pasta, the casserole also gets a significant boost in fiber and plant-based protein compared to traditional versions.

Key Health Highlights

  • No Canned Soups: Avoids the high sodium and preservatives found in many processed cream soups.
  • Good Source of Fiber: Features chickpea pasta, which provides more fiber than traditional white pasta, supporting digestive health.
  • Lean Protein: Uses boneless, skinless turkey breast for a high-quality, low-fat protein source.
  • Heart-Healthy Fats: The sauce is made with olive oil and just a small amount of butter, prioritizing unsaturated fats.
  • Gluten-Free: This recipe is naturally gluten-free thanks to the use of chickpea pasta and gluten-free flour and breadcrumbs.

FAQs About Healthy Leftover Turkey Casserole

The key is to have enough sauce to coat all the ingredients, as the pasta will absorb liquid while baking. Also, avoid overbaking—cook just until bubbly and heated through. Letting the casserole rest for 10-15 minutes before serving also helps the sauce settle and re-distribute.

A simple homemade cream sauce, like the one in this recipe, is a great substitute. It's made by creating a roux with a small amount of fat (butter/oil) and flour, then whisking in a liquid like milk and broth until it thickens.

Absolutely. You can use the same amount of any short pasta, like shells, rotini, or penne. Cook it al dente according to package directions before adding it to the casserole. Note that this substitution will mean the recipe is no longer gluten-free.

Stored properly in an airtight container, the casserole will last for up to 4 days in the refrigerator. Reheat individual portions in the microwave or a covered dish in the oven until warm.

Serving & Storage Tips

  • Serving: This casserole is a complete meal on its own, but it also pairs nicely with a simple green salad or steamed green beans.
  • Storing: Let the casserole cool completely before transferring to an airtight container. It will keep in the refrigerator for up to 4 days.
  • Freezing: For longer storage, you can freeze the casserole for up to 3 months. For best results, freeze it in the baking dish, tightly covered with both plastic wrap and foil.
  • Reheating: To reheat, thaw the casserole overnight in the refrigerator. Bake, covered with foil, at 350°F for 20-25 minutes or until heated through. You can also reheat individual portions in the microwave.

Ingredient Substitutions

If you don't have chickpea pasta, you can use whole wheat, regular, or any other gluten-free short pasta.

Feel free to add other vegetables to the mix. Mushrooms, green beans, or corn would all be delicious additions.

To make this recipe dairy-free, substitute the butter with more olive oil or a vegan butter, and use an unsweetened, plain plant-based milk like almond or cashew milk.

For extra flavor, you can add a tablespoon of grated Parmesan cheese to the breadcrumb topping.
