What is a bubble-up casserole?

  • Ground Beef: If you can, go with a pack of lean ground beef.
  • Taco Sauce: I use the Oretgo brand, about two 8-oz. jars.
  • Taco Seasoning Mix: The original kind adds the perfect flavor.
  • Cheese: Shredded cheddar cheese is added to the top of the Mexican bubble up casserole and melted to perfection.
  • Biscuits: Refrigerated (buttermilk or homestyle) Pilsbury biscuits work perfectly, although any brand will do.

Variations

  • Toppings: light and flavorful toppings to consider are sliced black olives, diced tomatoes, shredded lettuce, a sprinkle of shredded cheddar cheese, a dollop of sour cream, sliced avocado, diced onion, sliced jalapenos, and extra salsa. Sharp cheddar cheese and green onions are great toppings as well.
  • Sides: since this dish is fairly hearty on its own, keeping the side options light is best. A few sides to consider are Mexican street corn, a nice helping of nacho or tortilla chips, and/or Mexican refried beans.
  • Spice & Flavor: switch up the flavors by adding chili powder, green peppers, and hot sauce.

Instructions:

  • Prepare the slow cooker with two sheets of parchment paper to create a sling for the pizza. Spray the parchment paper with nonstick cooking spray. Note- You DO NOT have to use parchment. I’ve made this without parchment and works great. Still be sure to spray with non-stick spray.

  • In a large skillet over medium high heat, cook the ground beef until no longer pink, crumbling as it cooks. Drain well and return the beef to the skillet.

  • Add the taco sauce, water, and taco seasoning to the skillet. Bring the beef mixture to a boil, reduce the heat to medium low, and allow it to simmer for five minutes or until sightly thickened.

  • Meanwhile, cut each biscuit into 6 pieces. Place the biscuit pieces into a large bowl or directly into the slow cooker on top of the parchment.

  • Fold the beef mixture and half of the cheese into the biscuits, evenly distributing the beef mixture throughout.

  • Cover the slow cooker and cook on low for 3 – 3.5 hours or until the biscuit dough is cooked through.

  • Remove the lid and sprinkle the top with the remaining cheese. Re-cover the slow cooker until the cheese is melted.

  • Lift the casserole from the slow cooker using the parchment foil sling. Transfer the pizza to a cutting board and carefully slice into pieces.

  • Serve the casserole with shredded lettuce, chopped tomatoes, or your choice of toppings.
