5 ingredient red pepper cream sauce pasta — the silky, vibrant weeknight dinner that comes together in 20 minutes

There are pasta sauces that take hours to develop flavor and then there is this red pepper cream sauce — a sauce that is so silky, so vibrant, and so deeply flavorful that people genuinely cannot believe it only has five ingredients and takes about twenty minutes from start to finish.

The color alone stops people in their tracks. That deep, vivid orange-red that coats every strand of spaghetti is the kind of thing that makes your dinner look like it belongs in a restaurant.

The secret is roasted red peppers. Whether you roast them yourself or use the jarred variety, they bring a sweet, smoky, slightly charred depth of flavor that forms the backbone of a sauce that tastes like it has been simmering for hours.

Blend them with garlic, cream, and a handful of parmesan and you have something genuinely extraordinary from embarrassingly simple ingredients.

I make this on nights when I want something beautiful and satisfying without actually putting in a lot of effort. Twenty minutes, one blender, one pot for the pasta, and dinner is done. Let's get into it.

Why you'll love this recipe

• Only 5 ingredients. Roasted red peppers, garlic, cream, parmesan, and pasta. That is the entire recipe. Sometimes the shortest ingredient list produces the most spectacular results and this sauce is the perfect example of exactly that.
• That color is absolutely stunning. The deep vivid orange-red of this sauce coating glossy spaghetti noodles is genuinely one of the most beautiful things you can put in a bowl. It looks impressive before you even take a bite.
• Rich, silky, and deeply flavorful. The roasted red peppers bring a sweet, smoky complexity that makes this sauce taste like something that simmered all afternoon. The cream rounds it out into something velvety and luxurious.
• Ready in 20 minutes. Blend the sauce while the pasta cooks and everything finishes at exactly the same time. This is the kind of pasta that makes weeknight cooking feel effortless.
• Vegetarian and genuinely satisfying. There is no meat anywhere in this dish and you simply do not miss it. The sauce is rich and filling enough to stand completely on its own.
• Incredibly versatile. This sauce works on spaghetti, penne, rigatoni, gnocchi, or as a dipping sauce for bread. IMO it is one of the most versatile sauces you can have in your weeknight cooking repertoire.

Ingredients with key notes

The 5 key ingredients:

• 2 jars roasted red peppers, drained — Jarred roasted red peppers are the weeknight friendly version and they work absolutely beautifully in this sauce. Look for peppers packed in water rather than oil for a cleaner, less heavy flavor. If you want to roast your own, place whole red bell peppers directly over a gas flame or under the broiler, turning occasionally, until the skin is completely charred and black all over. Transfer to a covered bowl to steam for 15 minutes then peel, seed, and use. The flavor of freshly roasted peppers is slightly more complex and smoky but the jarred version is genuinely excellent.
• 6 cloves garlic — Sauteed in butter until golden before being blended with the peppers. The garlic adds a savory, aromatic depth that anchors the sweetness of the roasted peppers. Do not use pre-minced jarred garlic here — fresh cloves make a noticeable difference in this simple sauce.
• 1 cup heavy cream — The cream transforms the blended roasted pepper puree from a simple sauce into something rich, silky, and velvety. Do not substitute with half and half or milk — the fat content of heavy cream is essential for achieving the right texture and coating quality.
• 1/2 cup freshly grated parmesan — Adds saltiness, savory depth, and a subtle nuttiness that rounds out the sauce beautifully. Freshly grated from a block of real parmesan, not the pre-grated canister variety. Pre-grated parmesan does not melt smoothly into sauces.
• 12oz spaghetti — The long strands of spaghetti work particularly well with this smooth, silky sauce. The sauce coats and clings to every strand beautifully. Linguine, bucatini, or any long pasta works equally well. Penne or rigatoni are also excellent if you prefer a shorter pasta shape where the sauce can pool inside the tubes.

Additional ingredients:

• 2 tbsp butter — For sauteing the garlic before blending. Butter adds a subtle richness to the flavor base.
• Salt for pasta water
• 1/2 cup reserved pasta water — The starchy pasta water helps thin the sauce to the perfect consistency and makes it cling to the pasta beautifully.
• Salt and black pepper to taste

For garnish:

• Fresh basil leaves
• Freshly grated parmesan
• Freshly cracked black pepper
• Red pepper flakes — optional

Step-by-step instructions

Step 1 — Bring the pasta water to a boil

Fill a large pot with water and bring it to a rolling boil. Season generously with salt — the water should taste pleasantly salty. While the water comes to a boil you have plenty of time to make the sauce. Time the pasta to finish cooking at roughly the same time the sauce is ready.

Step 2 — Saute the garlic

Melt the butter in a medium saucepan over medium heat. Add the whole garlic cloves and cook for 3-4 minutes, stirring occasionally, until lightly golden and fragrant. You are not looking for deep browning here — just enough cooking to take the raw edge off the garlic and develop a mellow, sweet, golden flavor. Watch the heat carefully — garlic goes from golden to burnt very quickly and burnt garlic will make the entire sauce bitter.

Step 3 — Add the roasted red peppers

Add the drained roasted red peppers to the saucepan with the golden garlic and butter. Stir well to combine and cook together for 2-3 minutes, letting the peppers heat through and absorb the garlicky butter. Season with salt and black pepper. Remove from heat and let the mixture cool slightly — about 5 minutes — before blending. Blending very hot liquids can cause pressure to build up in the blender which is both dangerous and messy.

Step 4 — Blend the sauce

Transfer the roasted red pepper and garlic mixture to a blender. Blend on high speed for 60-90 seconds until completely smooth and velvety. The sauce should be a beautiful deep orange-red color with no visible chunks. If you have an immersion blender you can blend directly in the saucepan which saves washing up another piece of equipment. Either way, blend until truly smooth — a partially blended sauce with chunks defeats the purpose of this beautifully silky sauce.

Step 5 — Add the cream and parmesan

Pour the blended red pepper puree back into the saucepan over medium-low heat. Stir in the heavy cream and whisk together until fully combined and smooth. Let the sauce simmer gently for 3-4 minutes, stirring occasionally, until it is heated through and has thickened slightly. The color will deepen and become even more vibrant as the cream incorporates. Remove from heat and stir in the freshly grated parmesan a handful at a time, stirring after each addition until fully melted and smooth. Taste and adjust the seasoning with salt and black pepper.

Step 6 — Cook the pasta

Add the spaghetti to the boiling salted water and cook according to package directions until just al dente — about 1-2 minutes less than the suggested time. Before draining, scoop out at least half a cup of the starchy pasta water and set it aside. This pasta water is your secret weapon for adjusting the sauce consistency.

Step 7 — Bring it all together

Drain the pasta and add it directly to the saucepan with the red pepper cream sauce. Toss together over medium heat using tongs, adding splashes of the reserved pasta water as needed to reach your preferred sauce consistency. The sauce should coat every strand generously and look glossy and vibrant. Toss for about 1-2 minutes until everything is beautifully combined and the sauce clings to the pasta perfectly.

Step 8 — Serve immediately

Divide the pasta between bowls using tongs, twisting the spaghetti into a nest as you plate. Top with fresh basil leaves, a generous shower of freshly grated parmesan, freshly cracked black pepper, and a pinch of red pepper flakes if you want a little heat. Serve immediately while the sauce is at its silkiest and most vibrant.

Serving suggestions

This red pepper cream sauce pasta is a complete and satisfying meal on its own but here are a few ways to make the dinner even more memorable:

• With garlic bread or focaccia — For soaking up every last drop of that gorgeous sauce left in the bowl. Non-negotiable in my kitchen.
• With a simple caprese salad — Fresh mozzarella, tomatoes, and basil with a drizzle of olive oil and balsamic. The fresh, light salad balances the richness of the cream sauce perfectly.
• With grilled chicken on top — Simple seasoned grilled chicken breast sliced and laid over the pasta adds protein and makes this a heartier meal.
• With sauteed shrimp — Quickly sauteed garlic shrimp tossed through the red pepper pasta is a combination that feels genuinely restaurant-worthy.
• With a glass of white wine — A crisp Pinot Grigio or Sauvignon Blanc pairs beautifully with the sweet, smoky flavors of the roasted red pepper sauce.

Storage tips

Leftover pasta: Store leftover pasta and sauce together in an airtight container in the fridge for up to 3 days. The pasta will absorb the sauce as it sits. Reheat in a skillet over medium-low heat with a splash of water or cream, tossing until the sauce loosens and everything is heated through.

The sauce on its own: The red pepper cream sauce stores beautifully on its own in an airtight jar in the fridge for up to 5 days. This makes it an excellent meal prep sauce — make a big batch on Sunday and use it throughout the week on pasta, as a pizza sauce, as a dipping sauce, or spooned over roasted vegetables.

Freezing the sauce: The sauce freezes well for up to 3 months — just the sauce, without the pasta. Let it cool completely then transfer to a freezer-safe container. Thaw overnight in the fridge and reheat gently in a saucepan over medium-low heat, whisking occasionally. You may need to add a small splash of cream while reheating to bring the texture back to its original silky consistency.

Freezing pasta: Cooked pasta does not freeze well — the texture becomes mushy after thawing. Always freeze just the sauce and cook fresh pasta when you are ready to eat.

Wrapping it up

Five ingredient red pepper cream sauce pasta is the recipe that proves you do not need a long ingredient list or complicated technique to make something truly stunning.

That deep vibrant color, that silky velvety texture, and that sweet smoky flavor that coats every strand of spaghetti — it is one of those dishes that looks and tastes far more impressive than the effort it requires.
