This supremely delicious (and supremely easy!) one–pot dish makes a great breakfast or brunch. Tostadas (tortilla chips are fine too) are layered with chorizo, cheese and a yummy sauce in a slow cooker and set on high for 4 hours. Then the eggs are added to poach in the mixture for the last 30 minutes. Most slow cooker dishes can sit on the "keep warm" setting for quite a while, but once the eggs are cooked, you should serve it right away.
Make-Ahead Tip: The casserole can be cooked on low for 8 hours. Raise heat to high before adding the eggs.
In a large skillet, heat the oil until shimmering. Add the sausage and cook over high heat, breaking it into small lumps with a spoon, until nearly cooked, about 5 minutes. Add the onion and cook until softened, about 5 minutes.2.
Add the red bell pepper and jalapeño, and cook until softened, about 5 minutes.3.
Add the scallion, cumin and cayenne, and cook for 1 minute longer.4.
Add the diced tomatoes along with their juice, the tomato sauce and the black beans. Season with salt and pepper. Bring to a boil.5.
Butter the insert of 4–quart slow cooker and arrange three tostadas in the bottom, breaking them to fill any empty spaces.6.
Scatter 1/3 of the cheese on top followed by 1/3 of the sauce. Repeat with the remaining tostadas, cheese and sauce.7.
Close the slow cooker and set on high for 4 hours. Crack the eggs into individual ramekins or small bowls.8.
After 3½ hours, using a small ladle or spoon, make 6 deep wells into the casserole and carefully pour the eggs into the wells.9.
Close the slow cooker and finish cooking until the egg whites are set and the yolks are runny, 20 to 30 minutes longer, depending upon the machine.10.
Serve over tostadas with the cilantro and shredded cheddar.
