Taco Casserole Ingredients
- 1 lb lean ground beef
- 2 cups salsa (mild, medium, or spicy to taste)
- 1 (16 oz) can chili beans, drained
- 1 (10 oz) can Rotel diced tomatoes with green chilies, drained about halfway
- 3 cups tortilla chips, lightly crushed
- 2 cups sour cream
- 1 (2 oz) can sliced black olives, drained

How to Make Cheesy Beef Taco Casserole
- Cook the beef. Preheat oven to 350°F (175°C). In a skillet, cook ground beef over medium heat until browned. Drain excess fat. Stir in salsa, Rotel, and chili beans. Simmer 2–3 minutes.
- Layer the base. In a greased 9×13-inch baking dish, spread half of the crushed tortilla chips. Top with the beef mixture.
- Add creamy layer. Spread sour cream evenly over the beef. Sprinkle with olives, green onions, and fresh tomatoes.
- Sauce & cheese. If desired, drizzle taco sauce over the creamy layer. Top with shredded cheese and the remaining tortilla chips.
- Bake. Bake uncovered for 20–25 minutes, until cheese is melted and bubbly.
- Serve. Garnish with extra toppings if desired—cilantro, avocado slices, or jalapeños.

Tips & Variations
- Extra moisture: Adding Rotel keeps the beef mixture juicy, while a drizzle of taco sauce prevents the top from drying out.
- Protein swaps: Substitute ground turkey or shredded chicken.
- Bean options: Use black beans or pinto beans instead of chili beans.
- Make ahead: Assemble casserole up to 24 hours ahead; bake when ready.
- Spice boost: Add taco seasoning to the beef or use a spicy salsa.
- Cheese lovers: Add a second cheese layer between chips and beef.
How to Store & Reheat
- Refrigerate: Store leftovers in an airtight container for up to 3–4 days.
- Freeze: Wrap casserole tightly in foil or store portions in freezer-safe containers for up to 2 months.
- Reheat (Oven): Cover with foil and bake at 350°F (175°C) for 20–25 minutes, until heated through.
- Reheat (Microwave): Warm individual portions on medium heat for 2–3 minutes, stirring halfway if needed.
- Pro tip: Add a spoonful of salsa or taco sauce before reheating to keep it moist and flavorful.
