How to Make Spicy Cream Cheese Jalapeño Chicken Spaghetti Bake

You’ll be surprised how fast this comes together—just 40 minutes from start to finish!

Step 1: Prep the Oven and Pasta

Set your oven to 375°F (190°C) and lightly coat a 9×13-inch baking pan with grease. Cook the spaghetti according to package instructions, then drain and set it aside.

Step 2: Sauté the Veggies

In a large skillet, melt 2 tablespoons of butter over medium heat. Stir in the finely chopped onion, minced garlic, and diced jalapeños. Cook, stirring occasionally, for 3 to 4 minutes until the ingredients become tender and aromatic.

Step 3: Make the Creamy Base

Stir in the softened cream cheese, sour cream, and milk.Whisk the ingredients until they become smooth and delightfully creamy.

Step 4: Add the Flavor

Gently combine the shredded chicken, cheddar cheese, mozzarella, and smoked paprika, then add salt and black pepper to taste. Stir until the cheese melts and the whole mixture feels like a warm, spicy hug.

Step 5: Combine and Assemble

Add the cooked spaghetti into the skillet and toss until fully coated. Pour the entire mixture into the baking dish you have ready.

Step 6: Top and Bake

Mix crushed buttery crackers with melted butter in a small bowl. Sprinkle evenly over the top of the casserole. Bake for 20–25 minutes, or until it’s bubbly and golden on top.

Step 7: Garnish and Serve

Add a sprinkle of chopped green onions or extra jalapeño slices if you prefer a spicier kick. Serve hot and prepare for compliments!

What to Serve with It

This dish is great by itself, but if you want to create a more complete meal, here are some of my favorite side options:

• Crisp green salad with a citrus vinaigrette
• Roasted broccoli or asparagus for some vibrant greens
• Cornbread muffins to soak up every bit of creamy sauce
• Pickled veggies or slaw to add a cool crunch against the spicy backdrop

Tips for Success

• Leave jalapeño seeds in for more heat, or use fewer peppers for a milder dish.
• Grate your own cheese for better melting and to skip any anti-caking ingredients.
• Allow the cream cheese to come to room temperature before adding it, ensuring it blends seamlessly into the sauce.
• Mix the topping last minute to keep it crispy and buttery, not soggy.
• Let it rest for 5 minutes before serving—it sets slightly and is easier to serve.

How to Store It

• Refrigerator: Keep in a sealed container for up to four days.
• Freezer: Seal it securely and store in the freezer for up to two months. Thaw overnight in the fridge.
• To reheat: Microwave individual portions or cover and bake at 350°F until heated through.
