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 or 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
Instructions
- Roast the garlic. Roast the garlic until soft and golden according to your preferred oven-roasting method. Once cool enough to handle, squeeze the softened cloves from their skins and mash them. For a quicker option, use about 6 cloves of minced garlic and sauté them with the onion.
- Roast the peppers. Set the oven to broil. Arrange the red bell pepper quarters skin-side up on a foil-lined baking sheet. Broil for about 10–15 minutes, or until the skins are heavily blackened.
- Steam and peel the peppers. Carefully transfer the hot peppers to a sealed heat-safe container or bag and let them steam for about 10 minutes. Remove the loosened skins with your fingers, then roughly chop the roasted peppers.
- Cook the pasta. 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. While the pasta cooks, heat the olive oil in a large pot over medium heat. Add the diced onion and cook for about 5 minutes, until softened. If using minced raw garlic instead of roasted garlic, add it during the final minute.
- Blend the vegetables. Carefully transfer the roasted peppers, roasted garlic, and softened onion to a blender or food processor. Blend until smooth and creamy.
- Make the sauce. Melt the butter in the same pot over medium heat. Pour in the roasted pepper mixture. Add the broth, heavy cream, and milk. Season with salt and black pepper, then stir well and gently heat until the sauce is warmed through.
- Add the cheese. Remove the pot from the heat. Stir in the freshly grated Parmesan and chopped parsley until the cheese melts into the sauce.
- Combine with pasta. Add half of the cooked fettuccine and gently toss until coated. Add the remaining pasta and toss again until evenly covered with the sauce.
- Serve. Garnish with additional Parmesan and fresh parsley. Serve the Roasted Garlic and Red Pepper Fettuccine Alfredo immediately while warm and creamy.
Tips & Tricks
- Watch the peppers closely: Broilers vary, so keep an eye on the peppers as they cook. The skins should blacken and blister without completely burning the flesh.
- Let the peppers steam: Sealing the hot peppers for about 10 minutes makes removing the skins much easier.
- Use freshly grated Parmesan: It melts more smoothly than pre-shredded cheese and gives the sauce a better texture.
- Don’t boil the Alfredo sauce: Gentle heating helps keep the dairy mixture smooth and creamy.
- Save some pasta water: If the sauce becomes thicker than desired, add a small splash of reserved pasta water to loosen it.
- For more garlic flavor: Add an extra roasted garlic clove or two if you prefer a stronger roasted garlic taste.
- For a lighter sauce: Use additional milk in place of some of the heavy cream, although the sauce will be slightly less rich.
- For a vegetarian version: Use vegetable broth rather than chicken broth.

FAQ
Can I make Roasted Garlic and Red Pepper Fettuccine Alfredo ahead of time?
Yes. The sauce can be prepared ahead and refrigerated in an airtight container for up to 3 days. Reheat it gently and add a splash of milk or pasta water to restore its creamy consistency.
How do I make the red pepper Alfredo sauce smooth?
Blend the roasted peppers, garlic, and softened onion thoroughly until completely smooth. A high-powered blender can produce an especially silky sauce.
Can I use jarred roasted red peppers?
Yes. Jarred roasted red peppers are a convenient shortcut. Drain them thoroughly before blending and adjust the seasoning because jarred peppers may already contain salt.
Can I use another type of pasta?
Absolutely. Linguine, spaghetti, penne, or rigatoni can all work well. Fettuccine is ideal because its wide shape holds the creamy sauce nicely.
Can I make this pasta vegetarian?
Yes. Use vegetable broth instead of chicken broth. Also check the Parmesan and other packaged ingredients if you need the entire dish to meet a specific dietary standard.
Why is my Alfredo sauce too thick?
The sauce can thicken as it cools or after the pasta absorbs some of the liquid. Stir in a little warm milk or reserved pasta water until it reaches your preferred consistency.
Storage
Refrigerator: Store leftover pasta in an airtight container in the refrigerator for up to 3 days.
Freezer: For best texture, freeze the sauce separately from the pasta for up to 2 months. Dairy-based sauces can sometimes change texture after freezing, so thaw slowly in the refrigerator.
Reheating: Reheat gently in a saucepan over low to medium-low heat. Add a splash of milk, cream, or pasta water and stir frequently until warmed through. Avoid high heat, which can cause the sauce to separate.
