To prepare a taco quiche beef recipe, you'll need: 1 pound ground beef 2 tablespoons kosher salt 1 teaspoon ground cumin 1 tablespoon ground coriander 1 cup (240 ml) melted butter 1 1/2 cups (120 g) brown sugar 2 tbsp. ground paprika 1/4 cup chopped scallions (optional) 1 chopped red bell pepper 1/2 cup diced red onion 1/2 teaspoon thyme 1/4 teaspoon cayenne pepper Instructions Preheat the oven to 425 degrees F. Cut the beef into 1/4-inch cubes. Place the cubed beef in the bottom of an oven-proof skillet and cook over medium-high heat, stirring occasionally, until the meat is no longer pink, 20 to 25 minutes. Remove the skillet from the heat and add the remaining ingredients. Simmer, tossing, for 5 to 10 minutes, or until heated through. Serve warm with tortilla chips.
