I still remember the first time I made this creamy roasted red pepper pasta on a random Tuesday when I had nothing planned for dinner. I pulled a jar of roasted red peppers out of the pantry, and twenty-five minutes later I was sitting down to one of the most satisfying bowls of pasta I’d made in months.

It’s rich, it’s a little smoky, and it comes together faster than I can set the table. Once you try it, I promise it’ll become one of those recipes you make on autopilot when you need something comforting without much effort. Let me walk you through exactly how I make it.

Ingredients

400g (14oz) long-cut pasta, such as linguine, fettuccine, or spaghetti
450g (16oz) jar of roasted red peppers, drained
1 tablespoon butter
1 medium white onion, diced
2 small cloves garlic, finely diced
240ml (1 cup) heavy or double cream, at room temperature
40g (1/2 cup) parmesan, freshly grated, plus extra for serving
1 tablespoon fresh parsley, finely chopped, plus extra for serving
1/2 teaspoon smoked paprika
A pinch of chilli flakes, to taste
Salt and black pepper, to taste

Note: These quantities are enough to serve 4 people comfortably as a main course.

I always reach for jarred roasted red peppers instead of frozen or fresh ones for this sauce. Frozen peppers release too much extra water when they thaw, which waters down the flavor of the sauce. Jarred peppers, on the other hand, come packed in a light brine that adds a subtle tang once it mixes into the cream, and they save me from having to char and peel peppers on a weeknight.

When it comes to cheese, I only use freshly grated parmesan. Pre-shredded, bagged cheese is coated in anti-caking powder that can make the sauce turn grainy instead of silky. And I make sure my cream is at room temperature before it goes into the pan, since cold cream is far more likely to split when it hits the warm sauce.

Variations

Dairy-free option: swap the butter for olive oil and use a full-fat coconut cream or cashew cream in place of the heavy cream, along with a dairy-free parmesan alternative.
Lighter version: use half-and-half or whole milk instead of heavy cream, though the sauce will be noticeably thinner and less rich.
Extra protein: stir in grilled chicken, pan-seared shrimp, or crumbled Italian sausage for a heartier meal. If you’re looking for another seafood dinner idea, Golden Coconut Shrimp Crunch Recipe is another delicious option to add to your meal plan.
Spicier kick: add extra chilli flakes or a small spoonful of harissa paste along with the cream.
Vegetable boost: toss in wilted spinach, sun-dried tomatoes, or sautéed mushrooms right before serving.
Herb swap: basil or oregano work nicely if you don’t have fresh parsley on hand.

How to Make Creamy Roasted Red Pepper Pasta?

This recipe comes together in just a handful of simple steps. Nothing here requires special skill, just a bit of timing so the pasta and sauce finish around the same time. Here’s exactly how I do it from start to finish.

Step 1: Cook the Pasta

Bring a large pot of generously salted water to a boil and add your pasta. Cook it until it’s just al dente, since it will finish cooking briefly in the sauce later. Before draining, scoop out a cup of the starchy pasta water and set it aside for later use.

Step 2: Drain the Peppers

Tip the jarred roasted red peppers into a strainer and squeeze out as much of the brine as you can with your hands. Don’t rinse them under water, since that brine carries a lot of the flavor the sauce needs. Just get rid of the excess liquid.

Step 3: Sauté the Onion and Garlic

Melt the butter in a large deep pan over medium heat and add the diced onion. Cook until soft and lightly golden, then stir in the garlic for another minute or so. Keep an eye on the garlic so it doesn’t catch and burn.

Step 4: Blend the Sauce Base

Scrape the butter, onion, and garlic straight into a blender along with the drained roasted red peppers. Blitz everything until completely smooth. If the mixture is too thick for your blender to handle, add a small splash of stock, milk, or water to loosen it up.

Step 5: Simmer with Cream

Pour the blended pepper mixture back into the pan and keep it on a low simmer. Stir in the room-temperature cream until it’s fully combined and the sauce turns a soft coral color. Let it bubble gently for a minute or two.

Step 6: Add Cheese and Seasoning

Stir in the freshly grated parmesan, parsley, smoked paprika, chilli flakes, and a generous pinch of salt and pepper. Keep stirring until the cheese melts smoothly into the sauce and everything looks glossy and thick.

Step 7: Toss and Serve

Use tongs to lift the pasta straight from the pot into the sauce, letting a little pasta water come along with it. Toss everything together until every strand is coated. If the sauce feels too thick, splash in more of the reserved pasta water until it loosens up.

Additional Tips for Making This Recipe Better

I always taste the sauce before adding the pasta, since that’s my last chance to adjust the salt and heat level.
If I want an extra silky texture, I add a small knob of butter right at the end, off the heat.
I never skip reserving pasta water, since it’s the easiest way to fix a sauce that thickens too much.
When my blender struggles with the thick pepper mixture, I add liquid a tablespoon at a time instead of dumping it all in at once.
I like to let the sauce simmer for just a minute after adding the cream, since boiling it too long can cause it to split.

How to Serve Creamy Roasted Red Pepper Pasta?

I like to serve this pasta straight from the pan into shallow bowls so the sauce doesn’t pool at the bottom. A generous scattering of extra grated parmesan and freshly chopped parsley on top makes it look like it came straight out of a restaurant kitchen.

For a pop of color and texture, I sometimes add a few extra chilli flakes or a drizzle of good olive oil right before serving. This pasta pairs beautifully with a side of garlic bread or a simple green salad with a lemony vinaigrette to balance out the richness.

If you’re serving a crowd, grilled chicken or pan-seared shrimp on top turns this into a more substantial main course. For another creative seafood meal, Easy Shrimp Sushi Tacos Recipe is a great recipe to enjoy on a different night.

Make Ahead and Storage

Refrigerating: Once cooled, transfer any leftovers into an airtight container and store them in the refrigerator. The pasta stays fresh for up to 3 days, though the sauce is at its creamiest within the first day or two.

Freezing: I don’t recommend freezing this pasta, since cream-based sauces tend to split and turn grainy once thawed. If you want to freeze ahead, freeze just the blended pepper base before adding the cream, then thaw and finish the sauce fresh.

Reheating: Warm leftovers gently in a pan over low heat, adding a splash of milk or pasta water to loosen the sauce back up. Microwaving works too, just heat in short bursts and stir often to keep the sauce from separating.
