How to Make Monterey Chicken Spaghetti Bake

Step 1: Prepare the chicken and pasta

Start by cooking your chicken breasts thoroughly—either by boiling or pan-searing—and then shredding or dicing them into bite-sized pieces. Meanwhile, boil the spaghetti until it’s just al dente, then drain and set aside to prevent overcooking later in the oven.

Step 2: Sauté aromatics and mix the sauce

In a large skillet, melt butter and sauté finely chopped onions and garlic until fragrant and translucent. Stir in the evaporated milk and sour cream to form a creamy base, seasoning with salt, pepper, and any preferred spices for a rich, flavorful sauce.

Step 3: Combine all components

In a large mixing bowl, blend the cooked chicken, spaghetti, sautéed onion-garlic mixture, diced green chilies, and shredded cheeses—saving some cheese to sprinkle on top for that golden finish. Mix everything thoroughly to ensure every strand of spaghetti is coated.

Step 4: Assemble and bake

Transfer the mixture to a greased casserole dish, sprinkle the remaining cheese evenly over the top, and bake at 350°F (175°C) for approximately 25-30 minutes, or until the cheese bubbles and turns golden brown.

Pro Tips for Making Monterey Chicken Spaghetti Bake

• Don’t overcook the pasta: Slightly undercook spaghetti to keep it firm after baking without turning mushy.
• Use freshly shredded cheese: It melts better and gives a creamier, richer finish than pre-shredded varieties.
• Season in layers: Taste and adjust seasoning at each step to build a balanced flavor profile.
• Let it rest: Allow the bake to cool for 10 minutes after baking to set and make serving easier.
• Double the green chilies: For more zest and color, feel free to increase the amount of green chilies.
