This Impossible Mexican Fiesta Casserole is a comfort food classic that delivers bold flavors with minimal effort. The name “impossible” comes from the unique technique where the biscuit dough rises above the filling during baking, creating a golden, flaky crust without pre-cooking. Inside, lean ground beef is seasoned simply and layered with fresh green bell peppers and ripe tomatoes, providing a juicy, savory contrast to the rich topping. A creamy blend of sour cream, mayonnaise, and sharp cheddar cheese adds a tangy richness that ties the dish together. Perfect for busy weeknights, family dinners, or potlucks, this casserole serves six and offers a satisfying mix of textures and tastes. Its a nostalgic dish that brings home-style warmth to your table using pantry staples you likely already have on hand.

Directions
-
Preheat oven to 375F (190C) and grease a 13x9-inch baking dish.
-
In a large skillet, cook the ground beef over medium heat, stirring occasionally, until browned and no longer pink.

Drain excess fat from the skillet and season the beef with salt and pepper to taste. Remove from heat and set aside.
-
In a medium bowl, combine the shredded cheddar cheese, sour cream, mayonnaise, and finely chopped onion. Mix well and set aside.
-
In a separate bowl, stir the Bisquick baking mix and water together until a soft, sticky dough forms.
-
With floured hands, press the dough evenly into the bottom of the greased baking dish, extending it about 1/2 inch up the sides.
-
Spread the cooked beef evenly over the dough layer.
-
Arrange the sliced tomatoes and chopped green bell peppers over the beef.
-
Spoon the sour cream and cheese mixture evenly over the vegetables and meat.
-
Sprinkle paprika over the top if desired.
-
Bake uncovered for 25 to 30 minutes, or until the dough edges are golden brown and cooked through.

Let the casserole cool for 5 minutes before cutting into squares and serving.
