Ingredients
- 6 large red bell peppers, quartered with 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 chicken broth
- 1/4 cup heavy cream
- 1/4 cup nonfat milk
- 1/2 cup freshly grated Parmesan cheese
- 1 tablespoon fresh chopped parsley
- Salt, to taste
- Black pepper, to taste
Instructions
- Roast the peppers: Set the oven to broil. Place the red bell pepper quarters skin-side up on a foil-lined baking sheet. Broil for 10–15 minutes, or until the skins are heavily blackened and blistered.
- Steam the peppers: Carefully transfer the hot peppers to a sealed food-safe bag or covered heatproof container. Let them sit for about 10 minutes. Remove the skins with your fingers, then roughly chop the softened peppers.
- Cook the fettuccine: 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.
- Cook the onion: Meanwhile, heat olive oil in a large 5-quart pot over medium heat. Add the diced onion and cook for about 5 minutes, until soft and translucent.
- Blend the vegetables: Add the roasted peppers, roasted garlic, and cooked onion to a blender or food processor. Blend until smooth and creamy.
- Build the sauce: Melt the butter in the same pot over medium heat. Pour in the roasted pepper and garlic puree. Add the broth, heavy cream, and milk. Season with salt and black pepper, then stir well.
- Simmer gently: Allow the sauce to warm through for a few minutes, stirring occasionally. Avoid boiling vigorously, as the dairy can become less smooth.
- Finish the Alfredo sauce: Remove the pot from the heat and stir in the freshly grated Parmesan and chopped parsley.
- Toss the pasta: Add half of the cooked pasta and gently toss until coated. Add the remaining fettuccine and continue tossing until all the noodles are covered with the sauce.
- Serve: Spoon the pasta into bowls and garnish with additional grated Parmesan and fresh parsley. Serve immediately.
Tips & Tricks
- Watch the peppers closely: Broilers vary considerably, so keep an eye on the peppers during the final few minutes. The skins should blacken, but the flesh should not become completely charred.
- Give the peppers time to steam: Sealing the hot peppers for 10 minutes makes the skins much easier to remove.
- Use freshly grated Parmesan: It melts more smoothly into the warm sauce than many pre-shredded varieties.
- Save some pasta water: If the sauce becomes thicker than you like, add a splash of reserved pasta water to loosen it.
- Make it vegetarian: Choose vegetable broth instead of chicken broth.
- For a halal-friendly version: Use halal-certified Parmesan or Parmesan made with suitable microbial/vegetarian rennet, and choose halal-certified chicken broth if using chicken broth.
- Adjust the creaminess: You can use a little more milk for a lighter sauce or slightly more cream for a richer result.
- Don’t overcook the pasta: Al dente fettuccine holds up better when tossed with the warm sauce.

Notes
For a deeper roasted flavor, allow the peppers to develop plenty of dark blistered spots under the broiler. The roasted garlic can be prepared ahead of time and refrigerated until needed.
For a lighter meal, serve smaller portions alongside a crisp green salad. For a heartier dinner, pair the pasta with roasted vegetables or warm crusty bread.

FAQ
Can I make Roasted Garlic and Red Pepper Fettuccine Alfredo ahead of time?
Yes. The roasted pepper and garlic sauce can be prepared ahead and refrigerated. When ready to serve, gently reheat the sauce and toss it with freshly cooked fettuccine.
Can I use jarred roasted red peppers?
Yes. Jarred roasted red peppers are a convenient shortcut. Drain them thoroughly before blending, and choose peppers without added alcohol-based ingredients if needed for your dietary requirements.
How can I make the red pepper Alfredo sauce thicker?
Allow the sauce to gently simmer for a few minutes before adding the Parmesan. You can also use less broth or add a little more Parmesan for a thicker consistency.
Can I make this pasta without heavy cream?
Yes. You can replace the heavy cream with additional milk, although the finished sauce will be lighter and less rich. A small amount of cream helps create the classic creamy texture.
What Parmesan should I use for a halal-friendly pasta?
Look for Parmesan that uses microbial or vegetarian rennet, or choose a halal-certified Parmesan. This is especially important because traditional Parmesan can use animal-derived rennet.
What can I serve with this pasta?
A green salad, roasted vegetables, steamed broccoli, or crusty bread all pair nicely with the creamy sauce and sweet roasted peppers.
Storage
Refrigerator: Transfer leftovers to an airtight container and refrigerate for up to 3 days.
Freezer: For the best texture, freeze the sauce separately from the pasta for up to 2 months. Dairy-based sauces can sometimes separate slightly after freezing, but gentle reheating and thorough stirring can help bring the sauce back together.
Reheating: Reheat leftovers gently in a saucepan over low to medium-low heat. Add a splash of milk, broth, or reserved pasta water and stir frequently until warmed through. Avoid overheating, which can cause the creamy sauce to become oily or grainy.
