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
- 2 tablespoons unsalted butter
- 1 cup vegetable or halal 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, for serving
- Extra chopped parsley, for serving
Instructions
- Roast the garlic. 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, or until very soft. Cool slightly, squeeze out the cloves, and mash. Set aside.
- Roast the red peppers. Set the oven to broil. Arrange the pepper quarters skin-side up on a foil-lined baking sheet. Broil for approximately 10–15 minutes, watching carefully, until the skins are well blistered and darkened.
- Steam and peel the peppers. Transfer the hot peppers to a covered heat-safe bowl and let them steam for about 10 minutes. Peel away the loosened skins and roughly chop the peppers.
- Cook the fettuccine. Bring a large pot of salted water to a boil. Cook the fettuccine according to package directions until al dente. Reserve about 1 cup of pasta water, then drain.
- Sauté the onion. Heat the olive oil in a large pot or deep skillet over medium heat. Add the diced onion and cook for about 5 minutes, or until softened and translucent.
- Blend the sauce. Add the roasted peppers, roasted garlic, and cooked onion to a blender or food processor. Blend until smooth.
- Build the Alfredo sauce. Melt the butter in the same pot over medium-low heat. Pour in the red pepper puree, followed by the broth, heavy cream, and milk. Season lightly with salt and black pepper. Stir until smooth and gently heated through.
- Add the cheese. Reduce the heat to low or remove the pan briefly from the heat. Stir in the freshly grated Parmesan until melted and creamy. Add the parsley.
- Combine with pasta. Add the cooked fettuccine in batches and gently toss until every strand is coated in the Roasted Red Pepper Fettuccine Alfredo sauce. If the sauce is too thick, loosen it with a small amount of reserved pasta water.
- Serve. Divide between bowls and finish with extra grated Parmesan, fresh parsley, and black pepper. Serve immediately.
Tips & Tricks
For the smoothest red pepper Alfredo sauce, blend the roasted vegetables thoroughly before adding them to the cream mixture. A high-speed blender creates an especially silky consistency.
Freshly grated Parmesan melts more smoothly than packaged pre-shredded cheese. Keep the heat low when adding it because excessive heat can cause a cheese-based sauce to become grainy.
For a quicker version, roast the peppers and garlic ahead of time and refrigerate them until you are ready to prepare dinner.
If you do not have time to roast whole garlic heads, sauté 5–6 minced garlic cloves with the onion instead. The flavor will be sharper but still delicious.
For an extra creamy red pepper pasta, replace the nonfat milk with whole milk or use a little additional heavy cream.
Always check packaged Parmesan or similar hard cheeses for halal suitability if that is important for your household, since production methods can vary.

FAQ
Can I make Roasted Red Pepper Fettuccine Alfredo ahead of time?
You can prepare the roasted pepper and garlic puree ahead of time and refrigerate it in an airtight container. For the creamiest texture, cook the pasta and finish the Alfredo sauce shortly before serving.
Can I use jarred roasted red peppers?
Yes. Well-drained jarred roasted red peppers are a convenient shortcut. Choose peppers without unnecessary flavorings and drain them thoroughly so they do not make the sauce watery.
Why is my red pepper Alfredo sauce too thick?
Parmesan and pasta starch can cause the sauce to thicken quickly. Add reserved pasta water a tablespoon or two at a time until you reach your preferred consistency.
Can I make this roasted red pepper pasta spicy?
Yes. Add crushed red pepper flakes or a small pinch of cayenne while warming the sauce. Start with a small amount so the heat does not overwhelm the sweet roasted peppers.
What protein goes well with creamy red pepper pasta?
Grilled halal chicken and shrimp both pair beautifully with the creamy sauce. Sliced halal beef sausage is another flavorful option for a heartier meal.
Can I use another type of pasta?
Absolutely. Linguine, spaghetti, tagliatelle, penne, and rigatoni can all work. Pasta shapes with ridges are especially good at holding onto the creamy sauce.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3–4 days. Because creamy pasta absorbs sauce while sitting, the fettuccine may become thicker after refrigeration.
Reheat gently in a skillet over low heat with a splash of milk or broth. Stir frequently until the sauce becomes creamy again and the pasta is heated through.
For the best texture, freeze the red pepper sauce separately rather than freezing fully assembled creamy pasta. Store the sauce in a freezer-safe container for up to 2 months, thaw overnight in the refrigerator, and reheat gently before combining with freshly cooked pasta.
