How to Make Taco Casserole
Step 1: Preheat and Prep Dish
Start by heating your oven to 350°F and lightly greasing a 9×13-inch baking dish with olive oil or non-stick spray. This ensures easy release and even heating for the layered casserole. Keep the dish nearby for quick assembly.
Step 2: Cook the Beef and Onion
In a large skillet over medium-high heat, warm the olive oil and add the ground beef and diced onion. Break up the meat as it browns. Cook until no pink remains and onions soften, about 5 minutes. Drain excess fat to keep the mixture lean and flavorful.
Step 3: Simmer with Tomatoes and Seasoning
Stir in the diced tomatoes with their juices and taco seasoning. Then lower the heat to medium. Let it simmer, stirring occasionally, until the sauce thickens and liquid reduces, around 7 minutes. Remove from heat once the beef mixture is saucy but not watery.
Step 4: Layer the Tortilla Chips and Beans
Spread the lightly crushed tortilla chips evenly across the bottom of the prepared dish to form a sturdy base. Spoon the refried beans over the chips. Spread them smoothly to create a creamy barrier that holds everything together.
Step 5: Add Beef and Cheese
Distribute the seasoned beef mixture over the beans in an even layer. Top generously with shredded cheddar cheese. Ensure full coverage for that bubbly, golden finish.
Step 6: Bake and Rest
Bake the assembled taco casserole in the preheated oven for 20 minutes, until the cheese melts and bubbles. Let it rest briefly after baking to set the layers. Garnish with fresh toppings before serving hot.
Pro Tips for Success
- Use Lean Beef: Opt for 90% lean ground beef to minimize fat drainage and maintain a cleaner flavor profile.
- Crush Chips Lightly: Break tortilla chips into large pieces to preserve crunch without turning the base to crumbs.
- Shred Cheese Fresh: Grate your own cheddar for better melting and avoid the waxy texture from pre-shredded varieties.
- Customize Toppings: Add fresh elements like lettuce post-bake to keep them crisp and vibrant.
How to Serve Taco Casserole
Garnishes
I love piling on shredded lettuce and diced tomatoes for a cool, fresh crunch that cuts through the warm cheese. A dollop of sour cream adds creamy tang. Sliced green onions bring a mild bite. These simple additions make each bite feel like a loaded taco.
Side Dishes
Pair this hearty taco casserole with a simple green salad dressed in lime vinaigrette for brightness. Mexican rice or black beans offer complementary textures without overwhelming the plate. For lighter meals, fresh fruit salsa provides a sweet contrast to the savory spices.
Creative Ways to Present
Scoop the baked taco casserole into individual bowls and let guests build their own with toppings for fun family interaction. Layer it in a trifle dish for a see-through display that highlights the colorful strata. Serve family-style on a large platter with extra chips nearby for casual dipping.
Make Ahead and Storage
Storing Leftovers
I store leftover taco casserole in an airtight container in the fridge, where it keeps well for up to 3 days. This method preserves the flavors and prevents drying out. Portion into single servings for easy grab-and-go lunches.
Freezing
For longer storage, wrap cooled taco casserole tightly in plastic wrap and foil before placing in a freezer-safe bag. It holds up for up to 2 months. Thaw overnight in the fridge to maintain texture. Avoid freezing if heavy on fresh toppings to prevent sogginess.
Reheating
Reheat portions in the microwave on medium power, covered with a damp paper towel, for 1-2 minutes to restore warmth without toughening the beef. For oven reheating, bake at 350°F covered with foil for 10-15 minutes to keep it moist. This ensures the cheese melts evenly every time.

Description
An easy oven-baked taco casserole layered with crushed tortilla chips, refried beans, seasoned ground beef, and melted cheddar cheese, topped with fresh taco garnishes for a family-friendly Mexican-inspired meal.
Ingredients
- 1 tablespoon olive oil, for sautéing
- 1 ½ pounds lean ground beef
- 1 medium yellow onion, finely diced
- 1 (14.5-ounce) can diced tomatoes, with their juices
- ¼ cup premium taco seasoning blend
- 2 cups robust tortilla chips, lightly crushed
- 1 (31-ounce) can prepared refried beans
- 3 cups sharp cheddar cheese, freshly shredded
- Optional toppings: fresh shredded lettuce, diced ripe tomatoes, a dollop of sour cream, sliced green onions, or extra tortilla chips for serving
Instructions
- Begin by preheating your oven to 350°F (175°C). Lightly coat a 9×13-inch baking dish with olive oil or your preferred non-stick spray, preparing it for assembly.
- In a large, heavy-bottomed skillet, warm the olive oil over a medium-high flame. Add the ground beef and diced onion, breaking up the meat as it cooks. Continue to cook until the beef is thoroughly browned and the onions have softened, approximately 5 minutes. Drain any excess fat from the pan.
- Integrate the diced tomatoes, along with their liquid, and the taco seasoning into the beef mixture. Reduce the heat to medium and allow the mixture to gently simmer. Stir periodically until the sauce thickens and most of the liquid has evaporated, which should take about 7 minutes. Remove the skillet from the heat.
- Evenly distribute the lightly crushed tortilla chips across the bottom of your prepared baking dish, forming the foundational layer of your casserole.
- Carefully spoon the refried beans over the layer of tortilla chips, spreading them into an even coating.
- Next, spoon the seasoned ground beef mixture over the refried beans. Crown the casserole generously with the shredded cheddar cheese.
- Transfer the dish to your preheated oven and bake for 20 minutes, or until the cheese is melted and bubbly, and the casserole is heated through. Allow to rest briefly before serving. Garnish with your favorite fresh taco toppings and serve hot, perhaps with additional tortilla chips for scooping.
Notes
- This recipe uses lean ground beef to reduce fat content.
- Customize with your preferred taco toppings for added freshness and flavor.
- Store leftovers in an airtight container in the refrigerator for up to 3 days; reheat in the oven or microwave.
