How to Make Tex Mex Chicken Spaghetti

Step-by-Step Instructions

1. Preheat & Prep: Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish. Cook your spaghetti according to package directions until al dente; drain and set aside.
2. Sauté Aromatics: In a large skillet or Dutch oven, heat olive oil over medium heat. Add onion and bell pepper and cook until softened, about 5-7 minutes. Stir in garlic and cook for another minute until fragrant. This forms the delicious base of our Creamy Chicken Pasta Bake.
3. Build the Sauce: Reduce heat to low. Stir in the cream of chicken soup, undrained Rotel, softened cream cheese, chicken broth, chili powder, cumin, and cayenne pepper (if using). Cook, stirring constantly, until the cream cheese is fully melted and the sauce is smooth and combined, about 5-8 minutes. Season with salt and pepper to taste.
4. Combine Ingredients: Add the cooked shredded chicken, cooked spaghetti, and 1.5 cups of the shredded cheese to the sauce. Stir gently until everything is evenly coated and well mixed.
5. Bake to Perfection: Pour the entire mixture into your prepared baking dish. Sprinkle the remaining 1/2 cup of shredded cheese over the top.
6. Serve: Bake for 20-25 minutes, or until the cheese is bubbly and lightly golden and the casserole is heated through. Garnish with fresh cilantro, if desired. Serve your glorious Tex Mex Chicken Spaghetti hot and enjoy every flavorful bite!

Fun Twists & Serving Ideas

• Spice it Up: Add a diced jalapeño to the sautéed veggies or a pinch more cayenne. A dash of hot sauce in the sauce wouldn’t hurt either!
• Veggie Boost: Stir in a can of drained black beans, corn, or even some spinach for extra nutrients and texture.
• Cheese Please: Experiment with different cheeses! A blend of Monterey Jack, cheddar, and a little smoked gouda could be divine.
• Make it Meatier: Brown some ground beef or turkey with taco seasoning and substitute or add to the chicken.
• Serving Suggestions: This dish is fantastic on its own, but also pairs wonderfully with a simple green salad, some warm tortilla chips, or a side of crusty bread to sop up all that amazing sauce.

Common Questions (FAQs)

• Can I make this ahead of time? Yes! Assemble the casserole in the baking dish, cover, and refrigerate for up to 24 hours. Add an extra 10-15 minutes to the baking time if baking from cold.
• What kind of chicken should I use? Leftover rotisserie chicken works beautifully for speed. Otherwise, boil or bake chicken breasts/thighs and shred them.
• Can I freeze Tex Mex Chicken Spaghetti? Absolutely! Once baked, let it cool completely, then cover tightly with foil and freeze for up to 3 months. Thaw in the fridge overnight before reheating.
• Is it very spicy? The recipe as written has a mild Tex Mex flavor from the Rotel and chili powder. You can control the heat by adjusting the cayenne pepper or using a mild vs. hot Rotel.
