This sauce comes together quickly, so before you start, bring a large pot of salted water to a boil so you can cook your pasta.
Combine the carrot and water in a large saucepan. Cook over medium heat for 8-10 minutes until carrots are very soft and water has evaporated. (Add more water if the carrots dry out before becoming soft.)
Add the minced garlic and saute for 30-60 seconds, or until fragrant.
Add the marinara sauce and use an immersion blender to puree the sauce until very smooth.
Simmer for 3-5 minutes.
Stir in the cream and heat through.
Serve over your favorite pasta.
Notes
-If you don't have an immersion blender, you can carefully pour the carrot mixture and marinara into a blender and puree. Then return to the pan to simmer.
