Preheat the oven to 350 °F. Cut the red bell peppers and the onion into stripes. Together with the garlic, place them on a baking sheet lined with parchment paper and bake for 10 minutes.

Step 2

In the meantime, cook the fettuccine according to the instructions on the package. Set aside.

Step 3

Get the bell pepper, the onion, and the garlic out of the oven and place them in a high speed blender together with the remaining ingredients and process until smooth.

Step 4

Pour the red bell pepper sauce into a saucepan and heat it up for a couple of minutes. Stir in the cooked fettuccine and serve immediately. Sprinkle with fresh chopped parsley and more red pepper flakes if you like. Enjoy!
