Chop and prep all the ingredients to begin.
Process the roasted red bell pepper in a food processor to make it into puree sauce.
Dice the onions into super small pieces. Cook the pasta and reserve 1 cup of pasta water.
Prep the shrimps by marinating with some lemon juice, black pepper and salt.
Heat a skillet with 1 tbsp. of olive oil and cook the shrimps until they are almost fully cooked. About 5 minutes. Remove the shrimps and place in a bowl.
In the same skillet, place another tablespoon of olive oil and sauté the onions until they are translucent in color.
Add in the black pepper, cream cheese, garlic powder, paprika, the processed red pepper and salt. Add 1 cup of pasta water and 1/2 cup of heavy cream. Mix everything together while breaking up the cream cheese and let the sauce simmer on low for a few minutes to obtain a creamy sauce.
Add in the cooked pasta, shrimp and 2 tbsps. freshly chopped basil. Cook everything together for 5 minutes so the pasta absorbs the sauce (while covered).
Remove the skillet from heat and grate some fresh parmesan cheese on top before serving.
