How to Make Red Pepper Alfredo Sauce
-
Preheat the Oven: Start by setting your oven to 450°F (232°C). This will prepare it for roasting the peppers until they’re beautifully blistered.
-
Prepare the Peppers: Halve the red bell peppers and remove the seeds. Place them skin-side up on a baking tray. Roast for 20-25 minutes until the skins are blistered and charred, adding a wonderful depth of flavor.
-
Blend the Mixture: Once the peppers have cooled slightly, peel off the skins to reveal their vibrant flesh. Blend the roasted peppers with the minced garlic until smooth and creamy.
-
Sauté in Skillet: In a large skillet over medium heat, melt the unsalted butter. Add your pepper mixture and let it simmer for about five minutes, allowing the flavors to meld beautifully.
-
Incorporate Cream: Slowly stir in the heavy cream, allowing the mixture to simmer gently for another five minutes. You want it thickened slightly, creating that luscious Alfredo texture.
-
Finish with Cheese: Remove the skillet from heat and mix in the grated Parmesan cheese until it’s fully melted. Season with salt and pepper to taste for that perfect savory balance.

Tips for the Best Red Pepper Alfredo Sauce
-
Choose Fresh Peppers: Pick firm, vibrant red bell peppers for the best sweetness and flavor in your sauce. Avoid any that are soft or wrinkled.
-
Roast for Flavor: Roasting intensifies the sweetness of the peppers. Don’t rush this step; allow them to char for that deep, rich flavor.
-
Don’t Overheat Cream: When adding heavy cream, stir gently over low heat. Boiling can cause it to separate instead of creating that creamy consistency in your Red Pepper Alfredo Sauce.
-
Use Fresh Parmesan: Opt for freshly grated Parmesan cheese. It melts more smoothly and gives a richer taste compared to pre-grated options.
-
Season to Taste: Taste your sauce before serving! Adjust with more salt and pepper if needed to elevate those delicious flavors.
