Ingredients
- 6 large red bell peppers, quartered, seeds and membranes removed
- 2 heads garlic, roasted and mashed, about 2 tablespoons
- 16 ounces fettuccine
- 1 tablespoon olive oil
- 1/2 medium onion, diced, about 3/4 cup
- 2 tablespoons butter
- 1 cup vegetable broth or halal-certified chicken broth
- 1/4 cup heavy cream
- 1/4 cup nonfat milk
- 1/2 cup freshly grated Parmesan cheese
- 1 tablespoon fresh parsley, chopped
- Salt, to taste
- Black pepper, to taste
- Extra Parmesan and parsley, for serving
Instructions
- Preheat the oven to 400°F (200°C). Slice the tops from the garlic heads to expose the cloves. Drizzle lightly with olive oil, wrap in foil, and roast for about 40–50 minutes, until the cloves are very soft. Cool slightly, squeeze out the roasted garlic, and mash. Set aside.
- Set the oven to broil. Arrange the red bell pepper quarters skin-side up on a foil-lined baking sheet.
- Broil the peppers for 10–15 minutes, or until their skins are well blackened and blistered. Transfer them to a covered heatproof bowl or sealed food-safe bag and let them steam for about 10 minutes.
- Peel away the loosened pepper skins and roughly chop the softened peppers. Set aside.
- Bring a large pot of generously salted water to a boil. Cook the fettuccine according to the package directions until al dente. Drain and set aside.
- Meanwhile, heat the olive oil in a large pot over medium heat. Add the diced onion and cook for about 5 minutes, until tender and translucent.
- Transfer the roasted peppers, roasted garlic, and cooked onion to a blender or food processor. Blend until completely smooth.
- Melt the butter in the same pot over medium heat. Carefully pour in the red pepper puree.
- Add the vegetable or halal chicken broth, heavy cream, and milk. Season with salt and black pepper. Stir well and gently heat the sauce until smooth and warmed through.
- Remove the pot from the heat. Stir in the freshly grated Parmesan and chopped parsley until the cheese melts into the sauce.
- Add the cooked pasta in batches, gently tossing until every strand is coated. Your Roasted Garlic and Red Pepper Fettuccine Alfredo should have a smooth, velvety sauce that clings easily to the pasta.
- Serve immediately with additional Parmesan, parsley, and freshly ground black pepper if desired.
Tips & Tricks
For the smoothest roasted red pepper pasta sauce, let the peppers steam after broiling. This makes their blackened skins much easier to remove.
Freshly grated Parmesan melts more smoothly than pre-shredded cheese. Add it after removing the sauce from direct heat to reduce the chance of the cheese becoming grainy.
If the sauce becomes too thick, stir in a splash of warm pasta water, broth, or milk. If you prefer a richer roasted garlic Alfredo, replace the nonfat milk with additional heavy cream.
Short on time? Instead of roasting whole garlic heads, mince about six fresh garlic cloves and sauté them with the onion during the final minute of cooking.
For additional protein, serve the pasta with grilled halal chicken, shrimp, or sliced beef sausage.

FAQ
Can I make roasted red pepper Alfredo pasta ahead of time?
Yes. You can prepare the roasted red pepper Alfredo sauce one or two days ahead and refrigerate it in an airtight container. Gently reheat the sauce before combining it with freshly cooked pasta.
Can I use jarred roasted red peppers?
Yes. Well-drained jarred roasted red peppers are a convenient substitute when you do not have time to roast fresh peppers. Choose peppers without unnecessary added flavors so the creamy sauce remains balanced.
What can I use instead of heavy cream?
Half-and-half or additional whole milk can work, although the finished sauce will be lighter. For the creamiest consistency, heavy cream gives the best result.
Why is my Alfredo sauce grainy?
Parmesan can turn grainy when exposed to excessive heat. Remove the sauce from direct heat before adding finely grated Parmesan and stir gently until melted.
What protein goes well with this fettuccine Alfredo recipe?
Grilled halal chicken, shrimp, or beef sausage all pair well with the sweet roasted peppers and savory garlic.
Is Roasted Garlic and Red Pepper Fettuccine Alfredo spicy?
No. Red bell peppers are naturally sweet rather than spicy. For gentle heat, add a small pinch of crushed red pepper flakes to the sauce.
Storage
Store leftover pasta in an airtight container in the refrigerator for up to 3–4 days. Because creamy pasta sauces thicken when chilled, add a splash of milk or broth when reheating.
Reheat gently in a saucepan over low to medium-low heat, stirring frequently. Individual portions can also be reheated in the microwave in short intervals.
The red pepper Alfredo sauce can be frozen separately for up to 2 months, although dairy-based sauces may separate slightly after thawing. Thaw overnight in the refrigerator and reheat slowly while whisking. For the best texture, cook fresh fettuccine when serving the thawed sauce.
