Roasted Red Pepper Pantry Pasta

The smell of roasted red peppers always pulls me back to a tiny kitchen in Rome where I watched an elderly neighbor make something impossibly creamy from just a jar of peppers and whatever she had in her cupboard. She told me the secret was patience and not being afraid of red sauces that were not tomatoes. This pasta became my go-to when I want something that feels fancy but uses ingredients I already have sitting around.

Last winter my sister dropped by unexpectedly after a terrible day at work and I had absolutely nothing in the fridge except jarred peppers and half a box of penne. I threw this together while she sat on my counter talking, and afterward she made me promise to write down the recipe because she said it tasted like a hug. Now she makes it for her own family whenever they need something comforting.

Ingredients

• 350 g (12 oz) dried pasta: Penne or rigatoni catch the sauce best but spaghetti works in a pinch
• 1 (340 g/12 oz) jar roasted red peppers: Drained well or your sauce will be too thin and watery
• 2 tbsp olive oil: This becomes the base of your sauce so use something decent
• 4 cloves garlic: Minced fresh, nothing from a jar or the flavor will be off
• 1 small yellow onion: Chopped into small pieces so they disappear into the sauce
• 1/2 tsp crushed red pepper flakes: Optional but adds a lovely warmth that balances the sweetness
• 100 ml (1/2 cup) vegetable broth or pasta cooking water: Pasta water actually works better because of the starch
• 50 g (1/4 cup) cream cheese or mascarpone: This is what makes it restaurant quality creamy
• 25 g (1/4 cup) grated Parmesan cheese: Plus more for serving because nobody ever regretted extra cheese
• Salt and black pepper: Taste as you go since the peppers and cheese are already salty
• Fresh basil or parsley: Chopped right before serving for that pop of green against the red

Instructions

Get your pasta water going:

Bring a large pot of salted water to a boil and cook the pasta until al dente, saving that cup of starchy pasta water before you drain

Build your flavor base:

Heat the olive oil in a large skillet over medium heat and sauté the onion until it goes translucent and soft, about 4 minutes

Add the aromatics:

Stir in the garlic and red pepper flakes if you are using them, cooking just until the garlic becomes fragrant, about 1 minute

Soften the peppers:

Add the drained roasted red peppers and let them cook for 2 to 3 minutes, stirring occasionally so nothing sticks

Make it silky:

Transfer everything to a blender with the broth, cream cheese, and Parmesan, then blend until completely smooth and creamy

Bring it together:

Pour the sauce back into the skillet over low heat and add the drained pasta, tossing everything together until each piece is coated

Finish and serve:

Add a splash of pasta water if the sauce needs loosening, then serve immediately topped with fresh herbs and extra cheese

This recipe has saved me so many times when I have people coming over and zero energy to shop. My friends always assume it took me all afternoon when really it took 20 minutes and a good blender.

Making It Your Own

The beauty of this recipe is how forgiving it is when you need to switch things up. I have made it with sun-dried tomatoes when I was out of roasted peppers and it was still fantastic. The key is keeping that creamy texture and the balance of sweet peppers against the salty cheese.

Varian

A creamy sauce without cream is such a great trick to have in your back pocket. This works with any pasta shape but I have found short pasta with ridges holds the sauce better than smooth strands. The peppers do most of the heavy lifting for flavor so do not be tempted to add too many other ingredients that might compete.

Serving Ideas

This pasta is rich enough to stand alone but sometimes I serve it with a simple green salad dressed with lemon and olive oil. A crusty piece of bread to swipe up any extra sauce never hurts either. The colors are so vibrant that it always looks beautiful on the table without any extra effort.

• A crisp white wine cuts through the creaminess perfectly
• Lemon wedges on the side let people brighten their own bowl
• Extra red pepper flakes for the heat lovers at the table

Save

Sometimes the simplest recipes become the ones we come back to again and again. This pasta has been my weeknight hero more times than I can count.

Frequently Asked Recipe Questions

→ Can I make this dish vegan?

Absolutely! Substitute the cream cheese or mascarpone with a plant-based alternative, and use nutritional yeast instead of Parmesan cheese. The sauce will still be creamy and flavorful.

→ What pasta shapes work best?

Penne, rigatoni, and spaghetti all work beautifully. The creamy sauce coats shorter pasta shapes especially well, but use whatever you have in your pantry.

→ How long does the sauce keep?

The blended sauce keeps refrigerated for up to 4 days in an airtight container. Reheat gently with a splash of pasta water or broth before tossing with freshly cooked pasta.

→ Can I use fresh red peppers instead?

You can roast fresh red peppers yourself, but jarred roasted peppers provide consistent flavor and save significant prep time. If using fresh, roast them until charred, then peel before blending.

→ How can I add more protein?

Stir in canned chickpeas, white beans, or shredded cooked chicken during the final heating. You can also serve with grilled tofu or add a dollop of ricotta.
