Ingredients You’ll Need

First things first—let’s gather everything you need. I promise, this list is simple, and chances are, you probably have most of these ingredients just hanging out in your kitchen already.

4 large russet potatoes (peeled and sliced into thin rounds)
1 lb ground beef (or turkey if you’re feeling healthier)
1 packet taco seasoning (don’t skimp on this, it’s the secret sauce!)
1 can of diced tomatoes (14.5 oz, don’t drain them)
1 cup onion (diced)
2 cups shredded cheddar cheese (you can never have too much cheese, right?)
1/2 cup sour cream (for a creamy, tangy kick)
1 cup taco sauce (mild or spicy, you do you!)
1 cup black beans (drained and rinsed)
1/2 cup green onions (chopped, for that fresh, crispy crunch)
Salt and pepper to taste
Olive oil (to grease the pan and give those potatoes a little extra crisp)

Trust me, this is a pretty easy grocery list. If you’re making it for a big family dinner or meal prep for the week, you can double everything without worrying about the flavors getting weird. This casserole is very forgiving—thankfully!

Prep Time: 15 Minutes | Cook Time: 35-40 Minutes

Before we start, here’s something to know: there’s zero need to rush. Honestly, this is the kind of recipe where you can take your time chopping, sautéing, and layering. No one’s timing you. But let’s make sure we get everything ready so we can move seamlessly from step to step.

Step 1: Prep the Potatoes

First, grab your russet potatoes, peel ‘em, and slice them into thin, even rounds. I’m talkin’ about thin—like, just a little thicker than a potato chip. This way, they cook up nice and crispy in the casserole and soak up all those delicious taco flavors. I like to give them a quick rinse under cold water to remove some of that starch (this helps them get crispy).

Then, heat up a skillet with a little olive oil, and sauté the potato slices for about 5 minutes, just to get a light golden brown on each side. You don’t need to cook them all the way through—just enough to give them a little crisp and start softening them up. You can also toss them with a bit of salt and pepper for flavor at this stage.

If you’re trying to cut down on time, you could also throw those potatoes in the microwave for a couple of minutes to give them a head start. But honestly, a little pan-frying makes them so much better.

Step 2: Cook the Ground Beef

While your potatoes are crisping up, go ahead and cook the ground beef (or turkey). Heat a large pan over medium heat, throw in your meat, and break it up with a spatula as it cooks. Once it’s browned, toss in your diced onion. Let that cook down for about 3-5 minutes until the onions become soft and a little translucent.

Then, stir in your taco seasoning and can of diced tomatoes. Don’t drain the tomatoes—they bring in so much extra moisture and flavor. Mix everything together, and let it simmer for a bit, about 5 minutes, so the flavors can all come together. You’ll know it’s ready when your kitchen smells like taco heaven.

Step 3: Layering the Casserole

Now comes the fun part: assembling the casserole. Grab a large casserole dish, and drizzle a little olive oil or spray it with cooking spray to keep everything from sticking. Start by laying down a layer of your sautéed potatoes. I usually go for about half of them on the bottom.

Next, spoon a layer of your taco beef mixture over the potatoes. I like to spread it out evenly so every bite has that meaty, flavorful goodness. After that, sprinkle a generous amount of shredded cheddar cheese on top (we’re going for ooey-gooey here, people).

Repeat the layers: potatoes, taco meat, cheese. Keep going until you’ve used up everything, but make sure you save some cheese for the top. The last layer should be that melty, cheesy heaven we all crave.

Step 4: Baking It All Together

Pop that casserole into the oven at 375°F for about 20-25 minutes, or until the cheese is all bubbly and golden brown. Seriously, keep an eye on it—it’s the kind of thing that goes from perfect to “oops, a little too brown” in a flash. But hey, a little crispy cheese never hurt anyone, right?

Step 5: The Toppings

While your casserole is baking, go ahead and prep your toppings. I like to go with fresh, crunchy green onions for a bit of contrast to all that cheesy goodness. A dollop of sour cream on top adds that creamy, tangy flavor that pulls everything together. You can also add a drizzle of taco sauce, or even some chopped cilantro if you’re feeling extra.

If you like a little more spice, throw in some sliced jalapeños, or top it off with a bit of salsa. The options are endless. It’s taco night—there’s no wrong way to top this.

Step 6: Serving It Up

Once it’s done baking, take that beauty out of the oven, let it cool for about 5 minutes (I know, I know, it’s hard, but trust me, you want to avoid burning your mouth), and serve it up.

Scoop out generous portions of that cheesy, beefy, potato-filled goodness and top it off with your choice of fresh ingredients. Get a fork in there, and enjoy! You’ll be getting compliments from everyone at the table. I’m not saying you’ll be crowned chef of the year, but…you will be.

Tips & Tricks to Make It Even Easier

Add veggies: If you want to sneak in some extra veggies, throw in some bell peppers, corn, or even some spinach. It’s an easy way to add color and nutrients to the casserole without compromising flavor.
Make it ahead: You can assemble this casserole ahead of time, cover it tightly, and store it in the fridge for up to 24 hours. When you’re ready to bake it, just pop it in the oven. It’s perfect for meal prepping!
Add a crunch: Want an extra crunchy layer on top? After baking, sprinkle some crushed tortilla chips over the casserole. It adds a nice crunch and extra taco vibe.
Leftovers for days: This casserole makes awesome leftovers. The flavors get even better the next day, and it’s the perfect dish to take to work for lunch. Just reheat it in the microwave for a couple of minutes, and you’re good to go.

Vegetarian Taco Casserole Recipe: A Meatless Marvel

So, you want to enjoy all the flavors of taco night but without the meat? No problem! This vegetarian taco casserole is just as delicious, hearty, and packed with that classic taco flavor we all love—minus the ground beef. You can still pile on the cheese, beans, and all those amazing toppings to create a filling, satisfying dish. Here’s how you can whip up this veggie-packed casserole.

Ingredients:

4 large russet potatoes (sliced thin for that crispy texture)
1 can black beans (drained and rinsed)
1 can kidney beans (drained and rinsed for extra protein)
1 can diced tomatoes (don’t drain)
1 packet taco seasoning
1 cup corn kernels (frozen or canned works fine)
1 cup chopped bell peppers (mix of red, green, or yellow for color)
1 small onion (diced)
2 cups shredded cheddar cheese (or any cheese you like)
1 cup sour cream (for topping)
1 cup salsa (to drizzle on top or mix in)
1 tablespoon olive oil (for sautéing)

How to Reheat a Casserole Without Drying It Out

Ah, reheating leftovers—the struggle is real, right? No one wants their delicious casserole to turn into a dry, sad mess. But don’t worry! Here’s a few tricks to keep your casserole nice and moist when reheating:

Use foil: If you’re reheating in the oven, cover your casserole with aluminum foil. This helps trap moisture and heat it evenly. Plus, it prevents the cheese on top from burning. Just make sure to remove the foil towards the last 5 minutes if you want the top to get crispy.
Add moisture: Before you reheat, drizzle a little bit of water or broth over the casserole to help keep it from drying out. You don’t need a ton—just a couple tablespoons will do. The steam will keep the casserole moist as it heats up.
Reheat at a lower temp: If you have time, reheat at a lower temperature, like 300°F. This prevents the casserole from cooking further and getting dry. Heat it gently for about 15-20 minutes (depending on size).
Microwave it with a damp paper towel: If you’re using a microwave, cover your casserole with a damp paper towel before reheating. This traps the moisture and keeps the casserole from getting tough or rubbery. Heat in intervals and check every 1-2 minutes.

These methods work wonders and will help your casserole stay as delicious as when it first came out of the oven!

Taco Casserole Side Dish Ideas

When you’re making taco casserole, you want sides that complement its bold, spicy flavors without stealing the show. Here are some great side dishes that pair perfectly with your taco casserole:

Mexican Street Corn (Elote): Sweet, spicy, and tangy—this classic side is a great match for the casserole. Grill corn on the cob and slather it with mayo, lime juice, chili powder, and a sprinkle of cotija cheese.
Guacamole & Tortilla Chips: You can never go wrong with guac. Creamy, tangy, and packed with flavor, guacamole pairs perfectly with the crunchy chips for a delightful sidekick to the casserole.
Spanish Rice: Fluffy, savory, and mildly spiced—Spanish rice (or Mexican rice) is a great option to balance the richness of the casserole. You could make it with tomatoes, onions, and a hint of cumin.
Black Bean Salad: A fresh, zesty black bean salad adds a nice contrast to the casserole. Toss black beans with diced tomatoes, red onion, cilantro, lime juice, and a little olive oil for a simple, refreshing side.
Simple Green Salad: Sometimes, a simple salad with romaine, avocado, and a squeeze of lime is just what you need to add some freshness and crunch to your meal.
Pico de Gallo: If you want something bright and fresh to cut through all the richness of the casserole, pico de gallo is the way to go. It’s made with tomatoes, onions, cilantro, lime juice, and a little chili for heat.

Any of these sides will make your taco casserole meal even better!
