Ingredients
Biscuit Base
- 1 box Cheddar Bay biscuit mix
- ¾ cup milk
Beef Mixture
- 1 ½ lb lean ground beef
- 1 large onion, diced
- ¼ cup water
- 1 packet taco seasoning
- 1 can diced tomatoes
Cheese Mixture
- 1 cup Colby Jack cheese, shredded
- ½ cup mayonnaise
- ½ cup sour cream
Topping
- 1 ½ cups cheddar cheese, shredded
- 2 tablespoon green onion, chopped
Instructions
- Preheat Oven: Preheat your oven to 350°F (175°C) and prepare a 9 x 13-inch casserole dish by spraying it with non-stick cooking spray.
- Mix Biscuit Base: In a mixing bowl, combine the Cheddar Bay biscuit mix, the enclosed seasoning packet, and milk until well combined.
- Set Biscuit Layer: Spread this biscuit mixture evenly in the casserole dish and bake for 5 minutes to slightly set the base.
- Brown Beef: While the biscuit base is baking, brown the ground beef in a large skillet with the diced onion over medium heat, breaking it up as it cooks.
- Drain Excess Grease: Once the beef is browned, drain any excess grease to keep the casserole from being greasy.
- Add Seasonings: Stir in diced tomatoes, water, and taco seasoning, mixing thoroughly to coat the beef in flavorful spices.
- Layer Beef: Remove the biscuit base from the oven and evenly spread the beef mixture over it.
- Prepare Cheese Mixture: In a separate bowl, mix together the sour cream, mayonnaise, and shredded Colby Jack cheese.
- Add Cheese Layer: Spread this creamy cheese mixture evenly over the beef layer in the casserole dish.
- Top with Cheddar: Finish by sprinkling shredded cheddar cheese on top for a melty, cheesy finish.
- Bake Casserole: Bake the casserole for about 30 minutes, until the cheese on top is melted, bubbly, and golden brown.
- Cool and Serve: Let the casserole cool for at least 10 minutes before slicing and serving, garnish with chopped green onions if desired.
Notes
- For a spicier casserole, add jalapeños or hot sauce to the beef mixture.
- You can substitute ground turkey or chicken for a leaner option.
- Use low-fat sour cream and mayonnaise to reduce fat content.
- Leftovers can be stored in the refrigerator for up to 3 days and reheated in the oven.
- Make sure to drain excess grease from the beef to prevent a greasy casserole.
