Ingredients

  • 2 cups large shell macaroni
  • 3 cups diced chicken or ham
  • 2 cans cream chicken soup
  • 2 cans chicken broth or milk
  • 1 chopped onion
  • 1 cup Velveeta cheese
  • 3 cups chopped celery
  • 1/2 cup green pepper (optional)

Instructions

  1. Combine all ingredients in a large dish and soak overnight.
  2. Bake uncovered at 350°F for 1 hour.

Tips & Substitutions

For best results, use leftover chicken or ham to save time. If you prefer a lighter option, substitute the cream chicken soup with a homemade white sauce. Feel free to add other vegetables like mushrooms or carrots for extra flavor and nutrition. Make sure to let the casserole soak overnight to allow the pasta to absorb the flavors. This dish is also great for potlucks or family gatherings.

Serving Suggestions

Serve the casserole hot, garnished with fresh herbs like parsley or chives for added color. It pairs beautifully with a side salad, such as Celery Almondine, or crusty bread to soak up the creamy sauce. For a heartier meal, consider serving alongside grilled vegetables or a light soup. This comforting dish is perfect for family gatherings or a cozy weeknight dinner.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, simply place in the oven at 350°F until warmed through, about 20-25 minutes. You can also microwave individual portions, but be sure to cover them to retain moisture. This dish can also be frozen for up to 2 months, though the texture may change slightly upon reheating.

Frequently Asked Questions

Can I use a different type of cheese instead of Velveeta?

Absolutely! While Velveeta provides a creamy texture, you can substitute with shredded cheddar, mozzarella, or a blend of your favorites. Just be sure to adjust the quantity to maintain the creaminess. Remember that different cheeses can alter the flavor profile, so choose one that complements your other ingredients.

Can I make this casserole vegetarian?

Yes, you can easily adapt this recipe for a vegetarian option. Omit the chicken or ham and replace it with additional vegetables like bell peppers, spinach, or mushrooms. You could also add beans for protein. Additionally, swap the cream chicken soup with a vegetable-based cream soup or a homemade white sauce to keep it rich and flavorful.

How do I know when the casserole is done baking?

The casserole is done when it is bubbly and the pasta is tender. You can check the internal temperature; it should reach at least 165°F. If the top is browning too quickly, cover it loosely with foil for the remaining baking time. Let it sit for a few minutes after baking to firm up before serving.
