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.

Everyone has spaghetti noodles in their pantry! Just stop at the store and grab any remaining ingredients you don’t have on hand. Now dinner can be prepped and in the oven in 20 minutes. I love easy one-pan dinners and this one is certainly a keeper!

1. Cook and Drain the Spaghetti: Break the spaghetti in half and cook it according to the package directions until it is al dente. Drain then set aside.
2. Preheat Oven/ Prep the Baking Dish: Before you assemble this recipe, preheat the oven to 350 degrees Fahrenheit and spray a 9X13 baking dish with cooking spray.
3. Combine the Cheeses, Sour Cream, Ricotta Cheese, Egg, and Seasonings: In a large bowl, whisk together the Monterey jack cheese, ½ cup parmesan cheese, sour cream, ricotta cheese, egg, salt, pepper, and garlic powder.
4. Add the Spinach, Fried Onions, and Spaghetti to the Cheese Mixture: Add the spinach, 3 ounces of the crispy fried onions, and cooked spaghetti to the cheese mixture. Toss thoroughly to combine the ingredients altogether.
5. Bake: Cover with foil and bake for 30 minutes.
6. Add Toppings and Finish Baking: After 30 minutes, spread the remaining fried onions and parmesan cheese on top of the spaghetti. Bake for an additional 5-8 minutes until the top is golden brown and crispy.
