Taco Beef Biscuit Casserole

This taco beef biscuit casserole layers seasoned ground beef, peppers, and diced tomatoes under tender biscuit dough and a creamy sour cream topping, then bakes everything in one dish.

It borrows the bold flavors of tacos but uses simple refrigerated biscuits for the base, so there are no shells to fill and very little cleanup. A hot skillet and one baking dish are all you need.

Why This Taco Beef Biscuit Casserole Recipe Works

Taco seasoning and diced tomatoes with green chilies give the beef a lively, mildly spicy flavor without a long list of spices.

Sour cream and mayonnaise bake into a rich, creamy layer that keeps the biscuit dough tender and golden on top.

Everything cooks in one skillet and one baking dish, so the meal comes together fast on a busy weeknight.

Ingredients for Taco Beef Biscuit Casserole

  • For the beef mixture: one pound of lean ground beef, one chopped medium onion, one chopped medium bell pepper, one ten ounce can of diced tomatoes with green chilies, drained, and one packet of taco seasoning mix.
  • For the topping: one eight ounce can of refrigerated biscuit dough, one cup of sour cream, and one cup of mayonnaise.

Ground beef. Lean ground beef browns quickly and carries the taco seasoning, so choose ninety three percent lean to keep the casserole from turning greasy.

Onion and bell pepper. Chopped onion and bell pepper soften in the beef drippings and add sweetness and body to the filling.

Diced tomatoes with green chilies. Draining the can keeps the filling from getting watery, and the mild chilies add gentle heat and tang.

Biscuit dough. Refrigerated biscuit dough bakes into soft, golden mounds that soak up a little flavor from the filling below.

Sour cream and mayonnaise. This creamy pair browns lightly in the oven and forms a rich blanket that seals in moisture.

How to Make Taco Beef Biscuit Casserole

1. Heat the oven. Heat the oven to 350 degrees F and lightly grease a nine by thirteen inch baking dish.

2. Brown the beef. Cook the ground beef in a large skillet over medium heat, breaking it into crumbles, until no pink remains and it reaches 160 degrees F, then drain the fat.

3. Cook the vegetables. Add the onion and bell pepper to the skillet and cook for about four minutes until softened.

4. Season the filling. Stir in the drained tomatoes with green chilies and the taco seasoning and cook for two minutes so the flavors blend.

5. Make the topping. Stir the sour cream and mayonnaise together in a bowl until smooth.

6. Assemble the layers. Spread the beef mixture in the dish, drop spoonfuls of biscuit dough over it, and pour the sour cream mixture over the top.

7. Bake until golden. Bake for twenty five to thirty minutes until the biscuits are golden and cooked through.

8. Cool slightly. Rest the casserole for ten minutes before serving so the layers set.

How to Serve Taco Beef Biscuit Casserole

Scoop portions onto plates and top with shredded cheese, sliced jalapenos, or fresh cilantro. Homemade corn salsa and creamy buttermilk coleslaw add freshness, while stovetop bacon green beans make a simple vegetable side. Serve with a glass of fresh peach lemonade to cool the spice.

How to Store and Reheat Taco Beef Biscuit Casserole

Cool the casserole within two hours, cover it, and refrigerate for up to three days. Reheat single portions in the oven or microwave until the center reaches 165 degrees F. Because the sour cream and mayonnaise layer can separate, the casserole does not freeze well, so plan to eat the leftovers within the refrigerator window.

Tips and Variations for Taco Beef Biscuit Casserole

Drain well. Drain the beef and the canned tomatoes thoroughly so the casserole bakes up thick instead of soupy.

Season gradually. Taste the filling before adding extra salt, because the seasoning mix, tomatoes, and biscuits already contain plenty.

Add cheese. Sprinkle shredded cheddar or pepper jack over the top during the last five minutes of baking for a melted finish.

Use a thermometer. Check that the beef reaches 160 degrees F before assembling, and that the casserole is hot throughout after baking.

Space the dough. Leave small gaps between the biscuit pieces so heat reaches the center and they bake through.

Lighten it up. Swap in Greek yogurt for the sour cream if you want a slightly lighter topping.

Flag the allergens. This casserole contains wheat, milk, egg, and soy, and taco seasoning may contain additional allergens, so check every label.

Check trusted guidance. For safe cooking temperatures and leftovers, read the Texas AgriLife Extension food safety guide.
