What’s In This Sour Cream Pasta Sauce Recipe?

See the recipe card below for full ingredient amounts and recipe instructions!

• Butter – I like to use unsalted butter to reduce the amount of sodium in my cooking.
• Garlic
• All Purpose Flour: I use organic 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 like to use this low sodium vegetable stock for my recipes because it has great flavor… without all the salt. 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!

How Do You Make Alfredo Pasta with Sour Cream?

1. Cook pasta according to package instructions. Drain and set aside.
2. In a large saucepan or skillet, heat the butter over medium low heat. Add the garlic and sauté for 3 to 4 minutes until lightly browned. Add in the flour, and stir with a wooden spoon until the mixture is well combined. Pour in the vegetable stock, and stir again for 4 to 5 minutes over low heat until the sauce begins to thicken.
3. Add the sour cream and parmesan cheese to the pan. Stir well.
4. Toss the cooked pasta with the sauce, and heat until the pasta is warmed through and the sauce is bubbling.
5. Toss with fresh parsley, and add salt and pepper if desired. Serve immediately!
