Step‑by‑Step Instructions for Monterey Chicken Spaghetti
Step 1: Cook the Pasta
Begin by bringing a large pot of salted water to a boil. Add spaghetti and cook according to package instructions, typically 8-10 minutes, until al dente. Once cooked, drain the pasta in a colander and set it aside, allowing it to cool slightly while you prepare the sauce.
Step 2: Sauté Vegetables
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add ½ cup of chopped onion, ½ cup of chopped bell pepper, and ½ cup of sliced mushrooms. Sauté the vegetables for about 5-7 minutes, stirring occasionally, until they are soft and aromatic, creating a colorful base for your Monterey Chicken Spaghetti.
Step 3: Make the Sauce
Lower the heat and stir in one can (10.5 oz) of cream of chicken soup and 1 cup of sour cream. Sprinkle in ½ teaspoon each of garlic powder and onion powder, then pour in ½ cup of milk. Stir everything together until well combined and smooth, cooking for an additional 2-3 minutes until the sauce is heated through and creamy.
Step 4: Add Chicken and Cheese
Next, add in your cooked shredded chicken and half of the shredded Monterey Jack cheese (1 cup). Stir continuously until the cheese melts completely, and the chicken is warmed, allowing those flavors to meld beautifully together into the sauce for your Monterey Chicken Spaghetti.
Step 5: Combine with Pasta
Add the drained spaghetti directly into the skillet with the sauce mixture. Using a pair of tongs, gently toss the pasta with the sauce until every strand is well-coated and you see that creamy goodness enveloping your noodles. This should take about 2-3 minutes, ensuring even distribution.
Step 6: Optional Baking
If you prefer a baked version, preheat your oven to 350°F (175°C). Transfer the pasta mixture to a greased baking dish. Sprinkle the remaining half cup of Monterey Jack cheese on top and bake for 20-25 minutes, or until the cheese is bubbly and golden, creating a comforting crust.
Step 7: Serve
Once baked or simply stovetop-cooked, remove your Monterey Chicken Spaghetti from the heat. If desired, garnish with freshly chopped parsley for a pop of color and freshness. Serve warm and enjoy the cozy flavors of this delicious dish with your loved ones gathered around the table.

Make Ahead Options
These Monterey Chicken Spaghetti are perfect for meal prep enthusiasts! You can assemble the entire dish up to 24 hours in advance by preparing the sauce and tossing it with the cooked spaghetti, allowing the flavors to meld beautifully. Simply refrigerate the unbaked casserole in a covered dish. When you're ready to serve, preheat your oven to 350°F (175°C) and bake for 20-25 minutes until bubbly and golden. Alternatively, store leftovers in an airtight container for up to 3 days—just reheat them with a splash of milk to restore creaminess. By prepping ahead, you'll enjoy the comforting embrace of this creamy pasta dish with minimal effort on busy weeknights!

Monterey Chicken Spaghetti Recipe FAQs
How do I choose ripe ingredients for my Monterey Chicken Spaghetti?
When selecting your ingredients, look for bright, firm bell peppers and fresh mushrooms, avoiding any with dark spots or mushiness. For onions, choose those that feel heavy for their size with dry, papery skins for the best flavor and sweetness.
How should I store leftover Monterey Chicken Spaghetti, and how long will it last?
Store your leftover Monterey Chicken Spaghetti in an airtight container in the fridge for up to 3 days. It’s vital to let it cool to room temperature before sealing to prevent moisture buildup, which could affect the quality.
