Ingredients You’ll Need
- Butter
- Garlic
- All Purpose Flour: I use all purpose flour for all my recipes, I love the consistency of the butter & flour roux, which thickens the sauce.
- Low Sodium Vegetable Stock – I always use low sodium or no-salt-added broth or stock to start, and then I can add salt or other spices later if needed. Check out some fantastic low sodium recipes here!
- Sour Cream – the base of this recipe, this sour cream gives it a silky and creamy texture.
- Parmesan Cheese – gives that extra bit of flavor and richness to this dish. Whether you use a sharp real cheese parmesan, or a plant-based version, adding a little extra into the sauce (and for garnish) makes this dish delish. Some parmesan cheeses are not vegetarian, so make sure to check the labels before consuming.
- Parsley
- Pasta, I used a long fettucine noodle!
Substitutions and Variations
- Add sautéed veggies to this dish (spinach or mushrooms would be delicious)
- Or add your favorite cooked protein for a hearty meal.
- Use any pasta shape you like, we love fettuccine for this, but any medium or long pasta will do!

Even better than a restaurant can make
A great variety on one of my favorite foods…pasta yum
Great, simple recipe. I didn’t think you could make Alfredo sauce with sour cream! I used more garlic & extra black pepper because I’m accustomed to them. My 1st try was too salty–my own fault as I used too much bullion powder to make my broth. But adjusted & 2nd try was awesome, not too salty even with regular salted butter. Be careful as parm. cheese is very salty
