Heat the olive oil in a medium skillet or pot over medium-high heat.
Add the onions, tomatoes, jalapeño, chipotle pepper, garlic, salt, paprika and dried oregano. Cook for 10 minutes, stirring occasionally, until the onions and peppers soften and the mixture becomes very concentrated.
Stir in the chicken broth and cook for 30 more seconds.
Remove from the heat and stir in cilantro and lime juice.
Carefully transfer everything to a large blender and blend until it reaches your desired consistency. You could also use an immersion blender. A few pulses will leave the sauce slightly chunky, or you can puree it until it's completely smooth.
Taste and season with more salt if necessary. Serve immediately on top of eggs, tacos, burritos, and all your favorite Mexican foods.
Notes
Yield: Makes 2 cups of Ranchero Sauce.
Jalapeños: I removed the seeds and veins from the pepper to keep it mild, but you can leave them in if you want it a little more spicy.
Chipotle peppers in adobo sauce: I used 2, but feel free to use only 1 if you want it mild. If you're not a fan of chipotle peppers, you can leave it out entirely for a very mild ranchero sauce.
Storage: Store in an airtight container in the refrigerator for up to 10 days.
