This creamy roasted red pepper penne is exactly that for me: a weekend project that rewards patience with a deeply savoury, velvety sauce that tastes like it simmered for hours. The sweet, smoky scent of charring peppers mingling with garlic and thyme is the signal to slow down, pour a glass of sparkling water, and enjoy the process as much as the plate.

Ingredients You’ll Need

• 4 large red bell peppers (about 600g)
• 2 tablespoons olive oil
• 1 medium onion, finely chopped
• 3 cloves garlic, minced
• 1 teaspoon dried thyme (or 3 sprigs fresh)
• ½ teaspoon smoked paprika
• 400g tin chopped tomatoes
• 150ml double cream
• 350g dried penne pasta
• 50g grated Parmesan cheese (or vegetarian alternative)
• Salt and freshly ground black pepper, to taste
• Small handful fresh basil leaves, for garnish
• 1 tablespoon balsamic vinegar (optional, for brightness)

Tip: For the best roasted flavour, choose peppers that are firm and deeply red – they are sweeter and will yield a more vibrant sauce.

How to Make Creamy Roasted Red Pepper Penne

1. Roast the peppers. Preheat your oven to 200°C (180°C fan). Halve the peppers, remove the stems and seeds, and place them cut-side down on a lined baking tray. Roast for 30–35 minutes, until the skins are deeply charred and blistered, and the kitchen smells sweetly smoky. The peppers should feel soft when pressed gently.
2. Steam and peel. Transfer the hot peppers to a bowl, cover tightly with cling film, and leave for 10 minutes. This steam loosens the skins. When cool enough to handle, peel away the charred skins – they should slip off easily, revealing tender, fragrant flesh. Set the peeled flesh aside.
3. Sweat the aromatics. While the peppers rest, heat the olive oil in a large frying pan over a medium flame. Add the chopped onion and cook for 6–8 minutes, stirring occasionally, until it turns translucent and golden at the edges – you should hear a gentle sizzle. Add the minced garlic, dried thyme, and smoked paprika, and cook for 1 minute more until the garlic is fragrant but not coloured.
4. Build the sauce base. Pour in the tinned chopped tomatoes, scraping the bottom of the pan with a wooden spoon to lift any browned bits. Let the mixture simmer for 5 minutes, stirring now and then, until it thickens slightly and turns a deeper red. Season with a pinch of salt and pepper.
5. Blend until silky. Transfer the tomato mixture and the roasted pepper flesh to a blender or food processor. Whizz on high for 45 seconds to 1 minute, until the sauce is completely smooth and looks like velvet. For an extra-silky finish, add the balsamic vinegar at this stage – it brightens the flavours without tasting sharp.
6. Cook the pasta. Bring a large pot of salted water to a rolling boil. Add the penne and cook according to package instructions until al dente – typically 10–12 minutes. Reserve about 150ml of the starchy pasta water before draining.
7. Combine and finish. Return the blended sauce to the frying pan over a low heat. Stir in the double cream and grated Parmesan, then add the drained penne. Toss everything together for 2–3 minutes, letting the sauce cling to every tube. If the sauce seems too thick, loosen it with a splash of the reserved pasta water until it falls in glossy ribbons. Taste and adjust seasoning. Serve immediately, garnished with fresh basil leaves.

Tips From My Kitchen

• Roast the peppers yourself – it is non-negotiable: Jarred roasted peppers are convenient, but they are often packed in brine or oil that can make your sauce taste sour or watery. Roasting your own peppers caramelises their natural sugars and adds a genuine smokiness that is the foundation of this dish. The extra 20 minutes is entirely worth it.
• Do not skip the steaming step: Placing the hot peppers in a covered bowl creates a mini steam chamber that separates the skin from the flesh. If you try to peel them immediately, you will tear the soft flesh and lose precious flavour. Patience here pays off with a cleaner, more refined sauce.
• Reserve more pasta water than you think you need: The starchy water is the secret to a sauce that clings perfectly. It helps emulsify the cream and cheese, creating a silky coating rather than a thin or greasy one. I always keep a full mug aside, even if I only use half of it.
• Taste the sauce before adding the cream: After blending, take a spoonful of the tomato-pepper purée. It should be rich, sweet, and slightly smoky. If it tastes flat, add a pinch more salt or the balsamic vinegar – balancing the base before adding cream ensures a more nuanced final flavour.
• Use a good-quality Parmesan and grate it yourself: Pre-grated cheese often contains anti-caking agents that prevent it from melting smoothly. Grating a block of Parmesan yourself means it will dissolve seamlessly into the warm sauce, giving you a creamier, more cohesive result. My husband, who’s usually picky, asked for seconds the first time I made this – the difference was the freshly grated cheese.

Equipment You’ll Need

• Large frying pan or skillet
• Sharp knife and cutting board
• Baking tray and lining paper
• Mixing bowls (one large, one medium)
• Wooden spoon or spatula
• Blender or food processor
• Large pot for boiling pasta
• Colander

Common Mistakes to Avoid

• Overcrowding the pan: When sweating the onions and garlic, avoid piling them too high in the pan. If the pan is overcrowded, the ingredients will steam rather than sauté, leading to a watery, dull flavour. Use a pan large enough that the onions sit in a single layer to encourage proper browning.
• Wrong temperature: Cooking the sauce over too high a heat can cause the cream to split or the garlic to burn, turning it bitter. Keep the heat low when you add the cream, and warm it gently – you want the sauce to come together, not boil. A gentle simmer is your friend.
• Skipping the rest time: Letting the roasted peppers steam under cling film for a full 10 minutes is critical. If you rush this step, you will struggle to remove the skins cleanly, and bits of charred skin in the sauce will create a gritty texture. The rest time transforms the peeling process from a chore into a simple pleasure.

Delicious Variations to Try

• Spicy Version: Add one small dried chilli (such as a bird’s eye or arbol) to the pan with the garlic and thyme. Alternatively, stir in ½ teaspoon of red pepper flakes just before blending for a gentle, lingering warmth that complements the sweetness of the roasted peppers beautifully.
• Vegetarian/Vegan Option: Replace the double cream with 100ml of full-fat coconut milk or a thick cashew cream (soaked cashews blended with water). Omit the Parmesan, or use a plant-based alternative. The sauce will still be creamy and luscious, with a slightly different but equally delightful richness.
• Different Protein: For a heartier meal, add shredded cooked chicken (about 200g) or pan-seared halloumi slices on top. Toss the chicken into the sauce just before serving, or lay the golden halloumi over the finished pasta for a salty, savoury contrast.

What to Serve With Creamy Roasted Red Pepper Penne

• A crisp green salad with a simple lemon vinaigrette to cut through the richness.
• Warm, crusty garlic bread for soaking up every last drop of sauce.
• Steamed tenderstem broccoli or roasted asparagus for a green, earthy side.
