How To Make Roasted Red Pepper Pasta
- Prepare for roasting: Preheat the oven to 375°F, and drizzle 1 tablespoon of olive oil into the bottom of an 8x8 or 9x13-inch baking pan or casserole dish.
- Season the peppers, onion, and garlic: Place the bell peppers, onions, and garlic into the pan, and drizzle the remaining oil on top then sprinkle on the chili flakes and salt making sure they are coated.
- Roast the peppers: Roast for 25 minutes then flip the peppers over, toss the garlic and onions, and bake for 20 more minutes until the vegetables are softened, fragrant, and fork-tender.
- Cook the pasta: While the vegetables are roasting, boil the pasta according to package directions. Drain and reserve 1 cup of pasta water. Set aside.
- Make the creamy red pepper sauce: Remove the vegetables from the oven and add all of them large blender along with the pasta water and blend until smooth. Pour in the heavy cream and pulse until a smooth and creamy sauce is formed.
- Thicken the sauce: Pour the sauce into the pot that you used to boil the pasta. Bring the sauce to a simmer over low heat. Add the parmesan cheese, and cook for at least 20 minutes or until the sauce has reduced a bit and started to thicken.
- Add pasta and serve: Add the cooked pasta back to the pan and toss to combine then serve with additional shredded parmesan cheese and freshly chopped parsley if desired.
- If you don’t have an oven-safe dish, you can use a skillet to roast the vegetables and then transfer them to a pot to make the sauce.
- This recipe can easily be doubled or tripled for a larger gathering.
- Our roasted red pepper pasta uses fresh bell peppers to make the sauce. Using jarred bell peppers may cause the sauce to separate as there is too much oil on the peppers.
- Make sure you read the package instructions for cooking your pasta as every type of pasta cooks differently.
- Parmesan cheese is best finely shredded right off the block as it has the most flavor. Cheese from a shaker container will work in a pinch.
- Blend the sauce with fresh Italian herbs like basil, thyme, or oregano for a different flavor profile.
- Add cooked chicken, shrimp, or sausage to the pasta for a heartier meal.
- For a smoky flavor, use smoked paprika instead of red chili flakes.
- If you don't have heavy cream on hand, you can use whole milk however the pasta sauce may be thinner.
