1. Roast the Red Peppers (if using fresh peppers)

Preheat your oven to 450°F (230°C). Place the whole red bell peppers on a baking sheet lined with parchment paper. Roast for 20–25 minutes, turning occasionally, until the skins are charred and blistered.

Remove the peppers from the oven and transfer them to a heatproof bowl. Cover with plastic wrap or a plate and let them steam for 10 minutes. Once cool, peel off the skins, remove the stems and seeds, and roughly chop the peppers.

2. Cook the Pasta

Bring a large pot of salted water to a boil. Add the pasta and cook according to package instructions until al dente. Reserve 1 cup of pasta water before draining the pasta, then set the pasta aside.

3. Sauté the Aromatics

In a large skillet or saucepan, heat the olive oil over medium heat. Add the chopped onion and sauté for 4–5 minutes until softened and translucent. Stir in the minced garlic and cook for another 30 seconds, until fragrant.

4. Blend the Sauce

In a blender or food processor, combine the roasted red peppers, sautéed onion and garlic, smoked paprika, red pepper flakes (if using), heavy cream, and Parmesan cheese. Blend until smooth and creamy. Taste and season with salt and black pepper as needed.

5. Simmer the Sauce

Pour the blended sauce back into the skillet. Simmer over medium-low heat for 5–7 minutes, stirring occasionally, until the sauce thickens slightly and the flavors meld together. If the sauce seems too thick, add a splash of the reserved pasta water to reach your desired consistency.

6. Combine the Pasta and Sauce

Add the cooked pasta to the skillet with the sauce. Toss to coat the pasta evenly, adding more pasta water as needed to keep the sauce creamy and smooth.

7. Add Optional Ingredients

If desired, stir in baby spinach, arugula, or any additional proteins like grilled chicken or shrimp. Cook for 1–2 minutes until the spinach wilts or the proteins are heated through.

8. Plate and Serve

Divide the pasta among plates or bowls. Garnish with fresh basil or parsley, additional Parmesan cheese, and a squeeze of lemon juice for brightness. Serve immediately and enjoy!
