Easy Monterey Spaghetti

This unique and delicious Monterey spaghetti will be hit at the dinner table! Although it is meatless, it’s loaded with lots of creamy protein-packed cheeses. Sour cream, parmesan cheese, Monterey jack cheese, and an egg create a heavenly cheese mixture that gets tossed with spaghetti, spinach, and crispy fried onions. As it bakes, the result is incredible! The texture and flavors from the crispy fried onions take this pasta dish to the next level.

It’s great for a weeknight meal, but you can also serve it as a side dish since it’s meatless. Any way you enjoy it is delicious! Complete this meal by serving it with a beautiful wedge salad, breadsticks, and a side of fruit.

Monterey spaghetti is really simple to put together and doesn’t require a lot of ingredients. It’s so easy that even your kids can help you make it! You can find the measurements below in the recipe card.

• Spaghetti: Spaghetti noodles are cooked and drained before assembling.
• Monterey Jack Cheese & Parmesan Cheese: The perfect flavor combination of cheeses to melt as it bakes!

• Salt and Pepper: Season to taste.
• Garlic Powder: Adds a garlic flavor that compliments all of the ingredients.
