This Lightened Up Sun-dried Tomato Fettuccine Alfredo is the kind of meal that feels indulgent without weighing you down. Think silken, tangy sauce studded with sweet sun-dried tomato pieces and kissed with garlic and red pepper flakes, all tossed with a full 16 ounces of fettuccine. It’s a shortcut-friendly, weeknight-worthy pasta that still reads like a special-occasion dish. The flavors are bright, the texture is creamy but lighter than a traditional Alfredo, and the finishing sprinkle of fresh basil and Parmesan makes every forkful irresistible.
Why you’ll love this version
Classic Alfredo leans heavily on butter and cream, but this take keeps the charm while trimming richness. The oil from sun-dried tomatoes contributes an extra layer of flavor so you can use less butter or heavy cream. Low-sodium chicken broth and lowfat milk build body without dominating the profile, and a small amount of reduced-fat cream cheese gives a creamy mouthfeel. Parmesan and a touch of mozzarella provide savory depth and stretch without going overboard.
There’s also room to personalize the heat (adjust the red pepper flakes), the herbiness (a little more dried basil or a handful of fresh basil at the end), and the final texture (more pasta water for a silkier sauce). Follow the step-by-step directions below to get perfectly cooked fettuccine coated in a glossy, flavorful sauce.
Ingredients
- 16 oz fettuccine noodles
- 2 tablespoons oil from sundried tomatoes in oil jar
- 1/2 cup sundried tomato halves, drained and finely chopped
- 4 garlic cloves, minced
- 1/8–1/4 teaspoon red pepper flakes, or more to taste
- 2 tablespoons all-purpose flour
- 2 cups low sodium chicken broth
- 1 1/2 cups milk (I use lowfat)
- 1 tablespoon cornstarch
- 1 tablespoon tomato paste
- 1/2 tsp each dried basil, dried parsley, onion powder, salt
- 1/4 tsp each dried oregano, pepper
- 2 oz. 1/3 less fat cream cheese, cubed
- 3/4 cup freshly grated Parmesan
- 1/3 cup shredded mozzarella
- freshly grated Parmesan, for serving
- fresh basil, for serving
Make-ahead and meal prep notes
You can chop the sun-dried tomatoes and mince the garlic a day ahead to speed things up. The sauce reheats well — gently warm it on the stovetop with a splash of milk or reserved pasta water to bring it back to saucy life. If you plan to store leftovers, add a little milk when reheating to loosen the sauce so it coats the pasta smoothly.
Equipment
- Large pot for boiling pasta
- Large skillet or wide, heavy-bottomed saucepan
- Whisk and wooden spoon
- Measuring cups and spoons
- Colander and tongs
Step-by-step Directions
Follow these steps in order for a smooth, flavorful result. The list below rewrites the original instructions into clear, actionable steps while keeping all ingredient amounts exactly as listed.
- Bring a large pot of salted water to a vigorous boil. Add 16 oz fettuccine noodles and cook until just al dente according to package directions (usually 9–12 minutes depending on brand). Reserve about 1 cup of the starchy pasta cooking water, then drain the pasta and set it aside.
- While the pasta cooks, heat 2 tablespoons of oil from the jar of sun-dried tomatoes in a large skillet over medium heat. When the oil shimmers, add the 1/2 cup finely chopped sun-dried tomato halves and sauté for about 1 minute to release their flavor into the oil.
- Add 4 minced garlic cloves and 1/8–1/4 teaspoon red pepper flakes to the skillet. Cook, stirring constantly, for 30–45 seconds until the garlic is fragrant but not browned. This step builds the aromatic base of the sauce.
- Sprinkle 2 tablespoons all-purpose flour over the tomato-garlic mixture and stir to combine. Cook the flour for 1 minute, stirring, to remove the raw flour taste and begin thickening the base.
- Gradually whisk in 2 cups low sodium chicken broth, making sure to whisk continuously so no lumps form. Once the broth is fully incorporated and the mixture is smooth, add 1 1/2 cups milk (lowfat is used here). Continue whisking until the mixture is smooth and begins to thicken slightly.
- In a small bowl or cup, dissolve 1 tablespoon cornstarch in a tablespoon or two of the milk from your measuring cup to make a slurry. Stir the cornstarch slurry into the sauce, then add 1 tablespoon tomato paste and whisk until evenly distributed. The tomato paste adds color and a subtle umami note.
- Season the sauce with 1/2 tsp dried basil, 1/2 tsp dried parsley, 1/2 tsp onion powder, 1/2 tsp salt, 1/4 tsp dried oregano, and 1/4 tsp pepper. Taste and adjust the seasoning if needed — remember you’ll also be adding Parmesan, which adds saltiness.
- Reduce the heat to low and add 2 oz. 1/3 less fat cream cheese, cut into cubes. Stir or whisk until the cream cheese is fully melted and the sauce is smooth. Keep the sauce at a gentle simmer; avoid boiling vigorously so the dairy doesn’t break.
- Stir in 3/4 cup freshly grated Parmesan and 1/3 cup shredded mozzarella. Continue stirring until the cheeses melt and the sauce becomes glossy and velvety. If the sauce seems too thick, add a few tablespoons of the reserved pasta water to reach your desired consistency.
- Taste the sauce and, if desired, add up to the remaining amount of red pepper flakes for more heat. Adjust salt and pepper to your preference, remembering that the Parmesan contributes saltiness.
- Add the drained fettuccine to the skillet (or transfer the sauce to the pot of pasta). Toss thoroughly with tongs or two forks so every strand is evenly coated. If the sauce needs loosening, add small amounts of the reserved pasta water until the sauce clings to the pasta in a glossy coating.
- Plate the pasta and finish each serving with a sprinkle of freshly grated Parmesan and a few torn fresh basil leaves. Serve immediately while hot and creamy.
Tips for a perfect result
- Reserve pasta water: The starch in the cooking water is key to emulsifying the sauce and helping it cling to the noodles. Add it sparingly until you reach the desired silky texture.
- Don’t rush the sauté: Letting the sun-dried tomatoes and garlic bloom in the oil develops deeper flavor than adding them directly to the liquid.
- Keep heat low after adding dairy: Once the cream cheese and cheeses are in, use low heat to prevent separation and keep the sauce smooth.
- Cheese quality matters: Freshly grated Parmesan melts better and tastes brighter than pre-grated powders. Use the Parmesan listed in the ingredients for the best texture and flavor.
- Adjust the heat: The recipe lists 1/8–1/4 teaspoon red pepper flakes. Start low, taste, and increase if you like more kick.
Variations and add-ins
This Lightened Up Sun-dried Tomato Fettuccine Alfredo is a great template for customization. Add cooked, shredded chicken or sautéed shrimp for protein. A handful of baby spinach stirred into the finished sauce will wilt quickly and add color and nutrients. For a brighter finish, a squeeze of lemon just before serving lifts the flavors beautifully.
Nutrition-minded swaps
The recipe already cuts back on heavy cream by using lowfat milk and a modest amount of reduced-fat cream cheese. If you prefer, swap in a plant-based milk with similar consistency, but note that flavor and melt will differ. Use a reduced-sodium broth (as listed) to control salt and rely on freshly grated Parmesan for the savory finish.
Serving suggestions
Serve this pasta with a crisp green salad and a light vinaigrette to balance the creamy sauce. Garlic-roasted broccoli or a simple arugula salad with lemon adds peppery contrast. A loaf of crusty bread or a few toasted baguette slices are perfect for mopping up any leftover sauce.
Storage
Store leftover pasta in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop with a splash of milk or reserved pasta water to loosen the sauce and restore creaminess. Avoid high heat to prevent the sauce from separating.
Final thoughts
This Lightened Up Sun-dried Tomato Fettuccine Alfredo delivers on comfort-food craveability while staying thoughtful about richness and texture. It’s an excellent weeknight formula that can be dressed up for company or pared back for a cozy solo dinner. Once you’ve tried the balance of tangy sun-dried tomatoes, mellow garlic, and smooth, cheesy sauce, this will likely become a repeat go-to when you want something satisfying without tipping into overindulgence.
Enjoy the bright tomato notes, the gentle heat, and the satisfyingly silky sauce. Serve hot, garnish with extra freshly grated Parmesan and torn basil, and dig in.
