Step-by-Step Instructions

Step 1: Preheat & Prepare

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish. This ensures your casserole doesn’t stick and achieves that golden-brown cheesy crust.

Step 2: Sauté the Aromatics

In a skillet, heat olive oil over medium heat. Add onion and bell pepper and cook for 3–4 minutes, stirring occasionally, until fragrant and tender. These veggies form the flavor base that gives your casserole its Southern depth.

Step 3: Mix the Creamy Base

In a large bowl, whisk together cream of chicken soup, cream of mushroom soup, sour cream, Rotel tomatoes, garlic powder, paprika, cayenne, salt, and pepper. This mixture is the heart of your casserole — rich, creamy, and slightly spicy.

Step 4: Combine All Components

Add the cooked spaghetti, shredded chicken, sautéed vegetables, and half of the cheeses to the creamy sauce. Toss until everything is evenly coated.

Step 5: Bake Until Bubbly

Transfer the mixture to the prepared baking dish. Sprinkle the remaining cheese evenly over the top. Bake uncovered for 25–30 minutes, or until the top is golden and bubbling.

Step 6: Garnish & Serve

Let it cool for 5–10 minutes before serving. Garnish with fresh parsley or crushed red pepper flakes for a pop of color and extra heat.

Common Mistakes to Avoid

• ❌ Overcooking the spaghetti: Keep it slightly al dente; it continues cooking in the oven.
• ❌ Adding too much liquid: Drain your Rotel tomatoes properly to avoid a soggy texture.
• ❌ Skipping the resting step: Allowing the casserole to rest 5–10 minutes helps it set and slice cleanly.
• ❌ Under-seasoning: The creamy base dulls flavors; be generous with salt, pepper, and paprika.

Tip: Always taste the sauce before baking — it’s your last chance to adjust seasoning.

Storing Tips for the Recipe

• Refrigerator: Store leftovers in an airtight container for up to 4 days.
• Freezer: Freeze unbaked casserole up to 3 months; thaw overnight before baking.
• Reheat: Warm in the oven at 325°F (160°C) for 15 minutes or microwave individual portions with a splash of milk to maintain creaminess.

Meal-prep bonus: Divide into single-serve containers for quick, protein-packed lunches.
