Roasted Red Pepper Alfredo Recipe
Introduction
Roasted Red Pepper Alfredo is a creamy, flavorful twist on the classic Alfredo sauce, featuring the sweet, smoky taste of roasted red peppers. This dish combines simple ingredients to create a comforting pasta that’s perfect for weeknight dinners or special occasions.

Ingredients
- 5 ounces spaghetti or fettuccine
- 1 (12-ounce) jar of roasted red peppers, drained
- 4 tablespoons unsalted butter
- 3/4 cup heavy cream
- 2 cups finely grated Parmesan cheese
- 1 tablespoon chopped basil (plus extra for garnish)
Instructions
- Step 1: Bring a large pot of water to a boil. While waiting, puree the roasted red peppers in a blender or food processor. Strain the puree through a fine-mesh sieve into a bowl, pressing with a spatula to extract all the juice. Discard the solids and set the strained puree aside, aiming for about 3/4 cup.
- Step 2: Add the pasta to the boiling water and cook for about half the time recommended on the package. The pasta will finish cooking in the sauce.
- Step 3: While the pasta cooks, heat the heavy cream over medium-low heat in a large saucepan until it begins to simmer. Add the butter and whisk continuously until melted and combined. Stir in the strained red pepper puree, bring to a simmer, and cook for a few minutes.
- Step 4: Add the grated Parmesan cheese to the sauce and stir until melted. Then add the partially cooked pasta, tossing to coat. Continue to simmer the pasta in the sauce, stirring constantly, until the sauce thickens and clings to the noodles. Add a few tablespoons of reserved pasta water if needed to help thicken the sauce. Taste and season with salt and pepper as desired. In the last few minutes, stir in the chopped basil.
- Step 5: Once the sauce has thickened and coats the pasta well, serve immediately. Garnish with extra chopped basil and a sprinkle of Parmesan cheese.
Tips & Variations
- Use fresh basil if available for a brighter flavor, or substitute with dried basil if needed.
- If you prefer a spicier sauce, add a pinch of crushed red pepper flakes while simmering the cream.
- For a lighter version, substitute half of the heavy cream with milk, but be aware the sauce may be less rich.
- Reserve some pasta water before draining to adjust sauce consistency easily.
Storage
Store leftover pasta in an airtight container in the refrigerator for up to 2 days. Reheat gently in a skillet over low heat with a splash of milk or cream to loosen the sauce and prevent dryness.

Ingredients
Pasta
- 5 ounces spaghetti or fettuccine
Sauce
- 1 (12-ounce) jar of roasted red peppers, drained
- 4 tablespoons unsalted butter
- 3/4 cup heavy cream
- 2 cups finely grated Parmesan cheese
- 1 tablespoon chopped basil (plus extra for garnish)
Instructions
- Prepare the peppers: Bring a large pot of water to a boil. Meanwhile, puree the drained roasted red peppers in a blender or food processor. Pour the puree through a fine-mesh sieve into a medium bowl, pressing with a spatula to extract about 3/4 cup of strained pepper juice. Discard the solids and set the puree aside.
- Start cooking the pasta: Add the pasta to the boiling water and cook for about half the time indicated on the package instructions. The pasta will finish cooking later in the sauce.
- Make the sauce: In a large saucepan over medium-low heat, bring the heavy cream to a simmer. Whisk in the butter until fully melted and combined. Add the strained roasted red pepper puree, stir well, and simmer for a few minutes to meld flavors.
- Add cheese and finish sauce: Stir the grated Parmesan into the sauce until melted and smooth. Add the partially cooked pasta to the sauce, tossing to coat. Continue to simmer and toss the pasta constantly until the sauce thickens and adheres well to the noodles. If the sauce is too thick or sticky, add a few tablespoons of reserved starchy pasta water to loosen it. Grate an additional 1/4 cup Parmesan if desired for extra creaminess. Season with salt and pepper to taste. Stir in the chopped basil during the last few minutes of cooking.
- Serve: When the sauce is thick and coating the pasta nicely, serve immediately. Garnish with extra chopped basil and a sprinkle of Parmesan cheese for a fresh, flavorful finish.
Notes
- The pasta is intentionally undercooked initially so it can finish cooking in the sauce, absorbing maximum flavor.
- Reserve some pasta cooking water to adjust sauce consistency as needed.
- Straining the pepper puree removes fibrous solids, yielding a smooth, silky sauce.
- Use freshly grated Parmesan cheese for best melting and flavor.
- This dish is best enjoyed fresh as the sauce thickens upon cooling.
