Ingredients
Gathering your ingredients is half the battle, and for this recipe, it’s a breeze! Here’s what you’ll need to create this magic:
- 9-12 oz pkg. Fettuccine Noodles: Your favorite brand works perfectly.
- 1 Tablespoon Butter: Just a touch for sautéing our aromatics.
- 1-2 Garlic Cloves, finely diced: Garlic is non-negotiable for that classic Alfredo flavor! Adjust to your garlic-loving heart’s content.
- 2 Tablespoons Flour: This is our secret weapon for thickening the sauce beautifully.
- 1 cup Chicken Broth: Adds a lovely depth of flavor and helps create that velvety texture.
- 1 cup 1% Milk: The key to keeping this Alfredo “skinny” while still getting that creamy richness.
- 3/4 cup High-Quality Parmesan Cheese, grated or shaved: Don’t skimp on the good stuff here! It makes all the difference in flavor.
- 1/4 – 1/2 teaspoon Salt: To taste, of course.
- 1/4 teaspoon Pepper: Freshly ground is always best for a little kick.
- Italian Parsley, diced (optional garnish): For a pop of color and freshness.
How to Make It
Alright, apron on, let’s get cooking! It’s so simple, you’ll be amazed.
- Cook Your Pasta: First things first, get that fettuccine going! Cook your fettuccine noodles according to the package directions. Once they’re perfectly al dente, drain them and set them aside. I usually like to reserve a little bit of the pasta water, just in case, but we probably won’t need it for this lighter version.
- Aromatic Base: Grab a medium saucepan and melt your tablespoon of butter over medium heat. Toss in your finely diced garlic and sauté it for about a minute, until it’s wonderfully fragrant. You want to smell that deliciousness, but be careful not to burn it!
- Make the Roux: Now, whisk in the flour. Keep stirring for about 1 minute, cooking out that raw flour taste. This little mixture of butter and flour is called a roux, and it’s going to be the foundation of our creamy sauce.
- Whisk in Liquids: Slowly, and I mean slowly, start whisking in the chicken broth and then the milk. Keep whisking as you add them to ensure there are no lumps. A smooth sauce is a happy sauce!
- Simmer and Thicken: Bring the sauce to a gentle simmer. You’ll want to stir it frequently during this stage. Watch as it magically thickens up over the next 3-5 minutes. It should be just thick enough to coat the back of a spoon.
- Cheese Time! Remove the saucepan from the heat. This is crucial to prevent the cheese from clumping or becoming oily. Stir in your grated Parmesan cheese, salt, and pepper until the cheese is completely melted and the sauce is luxuriously smooth and creamy. Taste and adjust seasoning if needed!
- Toss It All Together: Now for the grand finale! Add your cooked fettuccine noodles directly into the saucepan with the sauce. Toss gently until every single strand of pasta is beautifully coated in that glorious skinny Alfredo sauce.
- Serve with Love: Plate up your pasta immediately. If you’re feeling fancy, sprinkle some fresh diced Italian parsley on top for a beautiful presentation. Enjoy every single bite!
Substitutions & Additions
The beauty of this recipe is its flexibility. Feel free to play around and make it your own!
- Broth Swap: No chicken broth? Vegetable broth works wonderfully here too for a vegetarian option.
- Milk Magic: If you don’t have 1% milk, feel free to use 2% or even whole milk. For a dairy-free version, unsweetened almond milk or cashew milk can work, though the creaminess might be slightly different.
- Add Some Veggies: Toss in some steamed broccoli florets, sautéed spinach, or roasted cherry tomatoes for added color, nutrients, and flavor.
- Protein Power: grilled chicken breast, sautéed shrimp, or even crispy pancetta make fantastic additions to turn this into a heartier meal.
- Spice It Up: A pinch of red pepper flakes added with the garlic can give it a nice little warmth.
Tips for Success
A few little tricks will ensure your Skinny Fettuccine Alfredo is absolutely perfect every time:
- Don’t Burn the Garlic: Keep an eye on that garlic while sautéing. Burnt garlic can make the whole sauce taste bitter.
- Whisk Constantly: When adding the liquids to the roux, continuous whisking is key to a smooth, lump-free sauce.
- Grate Your Own Cheese: Pre-shredded Parmesan cheese often contains anti-caking agents that can make the sauce a bit grainy. Grating your own from a block will give you the smoothest, meltiest sauce.
- Prep Ahead: You can dice your garlic and measure out your dry ingredients a day in advance to make weeknight cooking even faster.
- Sauce Consistency: If your sauce seems a little too thick after adding the cheese, you can thin it out with a tablespoon or two of milk or reserved pasta water (if you remembered to save some!).
How to Store It
Leftovers are a delicious possibility! Store any leftover Skinny Fettuccine Alfredo in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop over low heat, adding a splash of milk or water if the sauce seems too thick. While it’s still delicious, pasta dishes are always best enjoyed fresh!
FAQs
Got questions? We’ve got answers!
Is this recipe truly “skinny”?
Compared to traditional Fettuccine Alfredo, which often uses heavy cream and large amounts of butter, this recipe significantly cuts down on fat and calories by using milk and just a touch of butter, while still delivering that creamy, satisfying flavor. It’s a lighter indulgence!
Can I make the sauce ahead of time?
Yes, you can make the sauce separately and store it in the refrigerator for a day or two. When you’re ready to eat, reheat the sauce gently and then toss with freshly cooked pasta.
Why is my Alfredo sauce not creamy?
This usually happens if the flour wasn’t cooked properly with the butter (the roux), if the liquid wasn’t added gradually, or if the cheese wasn’t melted off the heat. Make sure you’re whisking well and removing the pan from the heat before stirring in the cheese!
