Mussels in marinara sauce is a quick & easy seafood recipe to make at home. Serve them with crusty bread as an appetizer, or over pasta as an entree. Spice them up with red pepper flakes to make Mussels Fra Diavolo.
In a large pot over medium heat, heat olive oil and sauté garlic (and red pepper flakes if using) for 1-2 minutes, being careful not to brown the garlic.
Add wine and bring to a boil. Cook until reduced by half, about 3 minutes.
Stir in marinara sauce and bring to a simmer. Stir in mussels, cover and cook until mussels open, 3 to 5 minutes; discard any mussels that do not open.
Season with salt, to taste, and sprinkle with parsley. Serve with crusty bread.
