Ingredients for Chicken Spaghetti Recipe Paula Deen

This casserole combines tender chicken, al dente spaghetti, and velvety cheese sauce for ultimate comfort.

The cheeses are critical here. Sharp cheddar provides the tang, while Monterey Jack ensures that signature Paula Deen creaminess. For best results, buy blocks and shred yourself—pre-shredded contains anti-caking agents that affect melt. The soups form the base, so Campbell’s is the standard, though store brands work. Chicken breasts should be poached until just cooked through to prevent dryness.

No green chiles? Diced jalapeños (fresh or canned) add similar heat. For a milder version, pimiento peppers work. The bell pepper can be any color, but green gives that classic Southern flavor. Rotisserie chicken saves time—about 4 cups shredded. If using fresh pasta, reduce cooking time by 3-4 minutes. Whole wheat spaghetti works but may need extra liquid.

Assemble ahead and refrigerate overnight—bake straight from the fridge, adding 10-15 minutes to cooking time. Leftovers keep 4-5 days refrigerated or freeze for 3 months. Reheat covered to maintain moisture. The flavors deepen after a day, making this perfect for meal prep.

Step-by-Step Instructions for Creamy Chicken Spaghetti Casserole

This method delivers a rich, velvety texture with perfectly balanced flavors in every bite.

Step 1: Prepare and Cook the Chicken

Begin by cooking the 2 lb boneless skinless chicken breasts until fully done. I prefer poaching in 1 cup chicken broth for added moisture and flavor. Simmer gently for 15-20 minutes until the internal temperature reaches 165°F.

Once cooked, remove from the broth and shred using two forks. The chicken should pull apart easily with a tender, juicy texture. Set aside the shredded chicken and reserve the cooking liquid for potential adjustments to the sauce consistency later.

Step 2: Cook the Spaghetti and Sauté Vegetables

Cook the 12 oz spaghetti noodles according to package directions until al dente. Break them into 2-3 inch pieces before cooking for easier serving. Drain and set aside, tossing with a touch of oil to prevent sticking.

Meanwhile, in a large skillet, melt the 0.5 cup unsalted butter over medium heat. Add the finely diced yellow onion and green bell pepper, sautéing for 5-7 minutes until soft and translucent. This builds the aromatic base that enhances the casserole’s depth.

Step 3: Create the Creamy Sauce Base

In a large bowl, combine the 2 cans cream of chicken soup, 1 can cream of mushroom soup, and 1 can diced green chiles (undrained). Stir in the 1 tsp garlic powder, 1 tsp onion powder, 1 tsp salt, and 0.5 tsp black pepper.

Fold in 1 cup of the cheddar cheese and 1 cup of the Monterey Jack cheese, reserving the other 1 cup of each for the topping. The mixture should be thick and creamy, with visible flecks of green chiles throughout.

Step 4: Combine All Elements and Bake

In a large mixing bowl, combine the cooked spaghetti, shredded chicken, sautéed vegetables, and sauce mixture. Stir thoroughly to ensure every piece of spaghetti is coated in the creamy sauce. The mixture will be thick and hearty.

Transfer to a greased 9×13 inch baking dish. Top with the remaining 1 cup cheddar cheese and 1 cup Monterey Jack cheese, spreading evenly. Bake at 350°F for 25-30 minutes until the top is golden brown and bubbly.

Step 5: Rest and Serve

Remove from the oven and let rest for 10 minutes before serving. This allows the cheeses to set slightly, making for cleaner portions. The casserole should have a rich, creamy texture with visible layers of chicken, spaghetti, and melted cheese.

The final dish serves 6 generously, with each portion showcasing the perfect balance of tender chicken, al dente pasta, and a velvety cheese sauce that defines this classic comfort food.

Dietary Considerations for This Dish

Gluten-Free Option

Swap the 12 oz spaghetti noodles for gluten-free pasta like Barilla or Jovial brands. I’ve tested both with great results. Cook for 1-2 minutes less than package directions to prevent mushiness in the casserole. 💡

Dairy-Free Adaptation

Use dairy-free cheese like Violife cheddar and Miyoko’s mozzarella for the topping. Replace the soups with dairy-free cream of chicken and mushroom soups—Imagine Foods makes excellent versions. The texture will be slightly different but still delicious.

Lower-Carb Version

Replace spaghetti with zucchini noodles or spaghetti squash. For zucchini, salt and drain 10 minutes before mixing to remove excess water. This version bakes in 20 minutes since the veggies cook faster. Honestly, it’s a great way to sneak in more veggies.

Lactose-Intolerant Fix

Use lactose-free cheeses like Sargento Ultra Thin slices or Green Valley Creamery shreds. The soups can stay as-is since they contain minimal lactose. I’ve found the flavor difference is negligible, and it’s a simple swap that keeps the dish just as creamy.

Vegetarian Twist

Replace chicken with 1 lb mushrooms or chickpeas for protein. Sauté mushrooms with the onions and peppers for added depth. Use vegetable broth for poaching if using chickpeas. The dish keeps its hearty texture, and the green chiles still shine. 🌱

Sodium Reduction

Use low-sodium chicken broth and no-salt-added canned soups. Skip the added 1 tsp salt and let diners season at the table. The cheeses and chiles provide plenty of flavor without excess sodium. This is my go-to when cooking for family watching their intake.
