Pre-heat a large soup pot over medium-high heat and drizzle with olive oil. Season cubed beef Chuck Roast liberally with Kosher salt and pepper then sear in the pan in a single layer, flipping once, until beef forms a brown crust. This will take about 2-3 minutes per side. Remove beef from pan and continue until all beef is seared; set aside.
In the same pan, add the Ground Beef and begin breaking up using a potato masher or wooden spoon. Season to taste with more salt and pepper and continue breaking down until beef is browned through, about 5-7 minutes; remove beef from pan and set aside along with the cubed beef.
Add the onions, peppers, garlic, and spices (smoked paprika, cumin, and oregano) to the pan, along with another pinch salt and pepper, and cook until veggies start to become tender, about 4-5 minutes, stirring frequently.
Pour the beer into the pot and use a wooden spoon to deglaze the bottom of the pan, scraping up any flavorful browned bits that may have formed while searing the beef. Add all remaining ingredients to the pot and bring mixture to a boil.
Reduce to low and simmer for 1 hour or until chuck roast cubes are fork-tender. Garnish with minced onions and cilantro to serve.
