This taco casserole is my go-to for busy weeknights when I want something easy and satisfying that everyone around the table will love. Whether you use beef or swap in turkey for a lighter touch, the melding of salsa, beans, fresh veggies, and creamy sour cream all tucked under gooey cheese makes this meal truly crave-worthy. Even my picky eaters clean their plates and ask for seconds. Serve it with chips, salsa, and a fresh green salad for a complete dinner that never gets old.
I first cooked this when my pantry was running low and my family needed a hot meal fast. It instantly became a rotation staple and even my retro casserole-hesitant dad looks forward to it.
Ingredients
- Lean ground beef: Works as a protein anchor and cooks quickly. Select bright red beef with little excess liquid in the packaging for best quality
- Salsa: Provides acidity and moisture which helps keep the casserole juicy. Look for chunky varieties with fresh flavors and check the salt content if you are watching sodium
- Chili beans: Add fiber and heartiness along with gentle spice. Go with beans that still hold their shape and are not overly mushy
- Crushed tortilla chips: Offer essential crunch and salt. Use sturdy, thick-cut chips and crush by hand for the best texture
- Sour cream: Adds cool, creamy tang. For a lighter touch, try Greek yogurt or low-fat options
- Sliced black olives: Bring a savory pop. Choose olives that are glossy and firm
- Chopped green onion: Supplies aroma and mild bite. Fresh, glossy green stalks are best and avoid any wilted ends
- Fresh tomato: Brightens the whole casserole. Select firm, ripe tomatoes that feel heavy for their size
- Shredded Cheddar cheese: Melts beautifully and finishes the dish. For extra flavor, choose a sharp or extra sharp variety and grate your own when possible
Instructions
- Gather Ingredients:
- Have all ingredients ready to go and pre-chopped before cooking for smoother assembly. This sets you up for the fastest prep
- Preheat Oven:
- Set your oven to 350 degrees F for even baking and spray your nine by thirteen inch casserole dish well to prevent sticking
- Brown the Beef:
- Set a large skillet over medium-high heat and crumble in the ground beef. Break it up as it cooks and let it brown fully about eight to ten minutes until all the pink is gone. This step builds the meaty base flavor for your casserole
- Simmer with Salsa:
- Pour in the salsa and reduce the heat to medium low. Let it simmer uncovered for twenty minutes or until most of the liquid has evaporated. After this, stir in the drained chili beans and let them heat through so their flavors blend into the mix
- Layer the Casserole:
- Sprinkle crushed tortilla chips evenly over the bottom of your baking dish. Spoon the hot beef mixture right over the chips taking care to spread it out for even layers. Dollop sour cream across the surface and gently spread to cover. Scatter black olives, green onion, and chopped tomato over the creamy layer for bites of brightness
- Top with Cheese:
- Cover the top generously with shredded Cheddar cheese. The cheese will melt into all the nooks for best texture and flavor
- Bake:
- Slip the dish into your preheated oven and bake for about thirty minutes. Look for bubbling edges and melted cheese for cue that it is ready. This helps everything meld together so every serving is hot, gooey, and satisfying
- Serve:
- Let the casserole sit five minutes before scooping. This resting time keeps each portion tidy. Spoon onto plates and serve with extra chips and fresh toppings if you like

My favorite part is layering everything and smelling the salsa and spices come to life in the oven. My kids love helping sprinkle the cheese and argue over who gets the crispiest corner scoop. Making this always draws everyone into the kitchen together.
How to Store Taco Casserole
Keep leftovers in a tightly sealed container or right in the casserole dish covered well with wrap or foil. Store in the fridge for up to four days. Rewarm single servings in the microwave or the oven for best texture. The chips will soften over time but the flavors stay rich and satisfying.
Ingredient Swaps and Additions
You can switch out beef for ground turkey or even shredded rotisserie chicken for a different spin. If you want an even more veggie heavy version, toss in drained canned corn, chopped bell peppers, or zucchini with the salsa step. For spice lovers a handful of pickled jalapenos scattered into the layers packs extra zing.
Serving Suggestions
This casserole is hearty enough on its own but extra festive served with chopped cilantro, avocado slices, extra salsa, or a squeeze of fresh lime. Round things out with a crunchy green salad and a side of rice. If you are serving a party, consider a toppings bar and let folks build their own custom plate.

Once you try this taco casserole, it is sure to earn a permanent spot in your dinner rotation. Enjoy the fun of making it your own with every batch.
