Heat the oil in a medium saucepan over medium heat.
Add white onion, chipotle peppers in adobo sauce and garlic. Cook until soft and fragrant, about 5 minutes.
Add tomato sauce, chicken broth, Kosher salt, smoked paprika, dried oregano, chili powder and lime juice, stirring to combine. Simmer on low for 5 minutes.
Using an immersion blender, or transferring the whole mixture to a stand blender or food processor, blend until smooth.
Set aside until ready to use.

Notes
To adjust heat, use more or less chipotle peppers in adobo sauce. They are pretty spicy and also smoky.
