Cook onion and pepper in large nonstick skillet over medium heat for about 3-5 minutes or until vegetables are soft. Set aside.
Meanwhile, place a medium saucepan over medium heat. Melt butter, then stir in minced garlic cloves. Cook about 1 minute or until garlic is soft and fragrant, stirring constantly.
Slowly add the heavy cream to the saucepan, whisk until cream comes to a boil. Reduce heat and simmer about 3-5 minutes or until it starts to thicken.
Stir in Parmesan cheese and 2 teaspoons Cajun seasoning until smooth and thick. Add more Cajun seasoning as desired. Then stir in cooked onions and peppers.
SNAPPY TIPS: You can omit the vegetables if desired and add your favorite vegetables or meats (such as andouille sausage, shrimp, crawfish, or chicken) for easy new flavors. You can also make this Cajun Alfredo Sauce all in one pan if desired.SNAPPY SUBSTITUTIONS: You can try using lighter creams or whole milk for a lighter version, but sauce will not thicken as much so you may want to also add a thickener.
