About the Ingredients

Cooked Chicken, Shredded

This tender chicken serves as the heart of the casserole, providing protein and flavor that melds beautifully with the creamy sauce.

Dry Spaghetti

Broken into pieces, the spaghetti adds a comforting texture and absorbs the rich flavors of the sauce as it bakes.

Cream of Mushroom Soup

A key ingredient that enhances the creaminess and adds depth of flavor, making the sauce luscious and rich.

Grated Sharp Cheddar Cheese

The star of the show! Its sharpness brings a delightful contrast to the creamy sauce, creating a mouthwatering topping.

Green Pepper and Onion

These veggies add a subtle crunch and fresh flavor, balancing the richness of the dish.

Diced Pimentos

These little bits of goodness add a pop of color and a slight tang, elevating the overall taste experience.

Tips & Tricks

Boil the Chicken with Aromatics

Add herbs or garlic to the boiling water for extra flavor in your chicken and broth.

Don’t Overcook the Spaghetti

Cook it just until al dente to ensure it doesn’t become mushy when baked.

Use Freshly Grated Cheese

For the best melting quality, opt for freshly grated cheese instead of pre-shredded.

Cover If Necessary

If the cheese is browning too quickly, loosely cover the casserole with foil to prevent burning.

Pro Tips

  • Choose the Right Chicken: A whole fryer chicken gives the best flavor and moisture for this dish.
  • Customize the Veggies: Feel free to add or substitute your favorite vegetables to suit your taste.
  • Let It Rest: Allow the casserole to sit for a few minutes after baking to help it set before serving.
  • Double the Recipe: This casserole freezes beautifully, so make a second dish for later!

Step-by-Step Instructions

Prepare the Chicken

Boil a whole fryer chicken in water until tender. Once cooked, shred the meat and measure out 2 cups, reserving the broth for later use.

Cook the Spaghetti

In the reserved chicken broth, cook the spaghetti until al dente. Drain well, ensuring not to overcook it, as it will finish cooking in the oven.

Combine Ingredients

In a large mixing bowl, combine the cooked spaghetti, shredded chicken, cream of mushroom soup, 2 cups of cheddar cheese, diced green pepper, onion, pimentos, and reserved chicken broth. Season with seasoned salt, cayenne, salt, and black pepper.

Assemble the Casserole

Pour the creamy chicken mixture into a greased casserole dish. Top generously with the additional cup of cheddar cheese, creating a deliciously gooey topping.

Bake to Perfection

Bake in a preheated oven at 350°F (175°C) for 45 minutes or until the casserole is bubbly and the cheese is golden. If it browns too quickly, cover loosely with foil.

Delicious Variations

Vegetable Medley

Add your favorite seasonal vegetables like broccoli or spinach for added nutrition and color.

Spicy Twist

Incorporate jalapeños or a dash of hot sauce for a kick that spice lovers will adore.

Gluten-Free Option

Substitute regular spaghetti with gluten-free pasta to make this dish suitable for gluten-sensitive individuals.
