Start by seasoning the beef chuck roast with kosher salt. In a slow cooker, heat butter and vegetable oil over medium heat in a skillet. Add the minced garlic and diced onions, sautéing until softened and fragrant, about 3-4 minutes.
To the skillet, add the chopped chipotles in adobo sauce, ground cumin, smoked paprika, chili powder, and cinnamon. Stir for about a minute until the spices bloom. Pour in the crushed tomatoes and mix thoroughly.
Transfer the onion and spice mixture over the seasoned beef in the slow cooker. Cover and cook on low for 8 hours or high for 4 hours until the beef is tender and easily shreds with a fork. Once cooked, shred the beef and mix it with the sauce.
In a mixing bowl, whisk together the eggs. In a clean skillet, add a touch of butter and scramble the eggs over medium heat until fluffy and just set. Remove from heat.
Prepare the tater tots according to package instructions, achieving that perfect crispy texture.
Lay out your large tortillas and begin with a generous spoonful of shredded chipotle beef, followed by scrambled eggs, crispy tater tots, and a sprinkle of chopped green onions. Roll the tortilla tightly to secure all the delicious fillings inside.
Slice the burritos in half for easy handling, and serve them warm with your favorite salsa or hot sauce on the side.
