How to Make Cajun Beef Spaghetti in Cheesy Three-Cheese Sauce

Cook the spaghetti according to package instructions. Drain and set aside.
In a large skillet, brown the ground beef over medium heat. Drain excess fat.
Add the chopped onion, minced garlic, and green bell pepper to the skillet. Sauté until the vegetables are tender.
Stir in the diced tomatoes, beef broth, Cajun seasoning, salt, and black pepper. Bring to a simmer and cook for about 10 minutes.
Reduce the heat and stir in the cheddar, mozzarella, and Parmesan cheeses until melted and creamy.
Combine the cooked spaghetti with the beef and cheese sauce, mixing well to coat.
Serve hot, garnished with chopped parsley.

Substitutions & Additions

Ground turkey or chicken can be used for a leaner option.
Feel free to add in other vegetables like mushrooms or zucchini for extra nutrition.
If you want more heat, add a dash of hot sauce or some crushed red pepper flakes.
Using gluten-free spaghetti is a great option for those with dietary restrictions.

Tips for Success

Don’t overcook the spaghetti; it should be al dente since it will continue cooking in the sauce.
Make sure to drain the ground beef well to avoid a greasy sauce.
You can prepare the beef mixture ahead of time and just reheat before combining with the spaghetti.
For a creamier texture, add a splash of cream or milk when mixing in the cheeses.
