Ingredients

Here’s what you’ll need to make this creamy, cheesy spaghetti bake:

12 oz spaghetti (about 3/4 box)
1 lb ground beef (or turkey)
1 small onion, diced
2 cloves garlic, minced
1 cup Monterey Jack cheese, shredded
1 cup cheddar cheese, shredded
1 cup mozzarella cheese, shredded
1 (10 oz) can diced tomatoes with green chiles (optional for extra flavor)
1 cup sour cream
1 cup cream cheese, softened
1 cup milk (or heavy cream for extra richness)
1 tsp paprika
1 tsp chili powder
1 tsp Italian seasoning
1/2 tsp salt (or to taste)
1/2 tsp black pepper
1 tbsp olive oil
Fresh parsley or cilantro for garnish

Instructions

Preheat the oven to 375°F (190°C). Grease a 9×13 baking dish lightly with cooking spray or butter.
Cook the spaghetti according to package directions until al dente. Drain and set aside.
Brown the ground beef in a large skillet over medium heat. Add diced onion and minced garlic, cooking until the meat is no longer pink and the onions are translucent.
Season the meat with paprika, chili powder, Italian seasoning, salt, and pepper. Stir well and cook for another 2 minutes.
Add tomatoes (optional) and stir until combined. Let the mixture simmer for 3–4 minutes.
Make the creamy sauce: In a mixing bowl, combine sour cream, cream cheese, and milk. Whisk until smooth and creamy.
Combine spaghetti and sauce: Add the cooked spaghetti to the skillet with the meat mixture. Pour in the creamy sauce and toss until everything is evenly coated.
Layer the casserole: Transfer the spaghetti mixture into the prepared baking dish. Spread it evenly.
Add the cheese: Sprinkle the Monterey Jack, cheddar, and mozzarella evenly over the top.
Bake for 20–25 minutes until the cheese is melted, golden, and bubbly.
Broil for 2 minutes (optional) to get a golden crust on top. Keep a close eye to avoid burning.
Garnish and serve: Let it cool for 5 minutes, then garnish with fresh parsley or cilantro. Serve hot.

Tips for Perfect Monterey Spaghetti Bake

Here are a few secrets to making this dish even better:

Don’t overcook the spaghetti. Al dente is best because it will continue cooking in the oven.
Let the cream cheese soften before mixing. It blends smoother and creates a silkier sauce.
Use a mix of cheeses. Monterey Jack adds creaminess, cheddar adds sharpness, and mozzarella gives stretch.
For a creamier texture, add an extra 1/2 cup of milk.
To prevent dryness, cover the casserole with foil for the first 15 minutes of baking, then remove it for the last 10 minutes.
