Adjust rack to top position and preheat oven to 425 degrees.
Heat a drizzle of oil in a large pan over medium-high heat. Add sausage* and cook, breaking up meat into pieces, until browned and cooked through, 6-8 minutes.
Stir in marinara; cook, stirring, until sauce is hot and sausage is coated, 1-2 minutes. TIP: If sauce seems too thick, add a splash of water.
Remove from heat, cover, and set aside until ready to use in Step 5.
