Pro Tips

- Add crushed tortilla chips on top for crunch
- Go vegetarian—skip the meat and double the beans and corn

Make Ahead Tips
Assemble the entire casserole (without toppings) up to 24 hours ahead. Cover and refrigerate. Bake straight from the fridge, adding 10 more minutes to the cook time. Add toppings after baking.
Servings & Time
Servings: 6–8
Cook Time: 45 minutes (15 min prep, 30 min bake)
Recipe and Instructions
Step 1: Brown the Beef
In a skillet, heat 1 tbsp olive oil over medium heat. Add 1 lb ground beef and cook until browned, breaking it up with a spoon, about 6–8 minutes. Stir in 1 packet taco seasoning and 1/4 cup water. Simmer for 2 minutes until thick.
Step 2: Mix Filling
In a large bowl, combine the cooked beef, 1 (15 oz) can black beans (drained), 1 cup frozen corn, and 1 cup chunky salsa. Stir until everything’s evenly coated.
Step 3: Prep Hashbrown Base
Grease a 9×13 baking dish. Press 1 (26 oz) bag of thawed shredded hashbrowns into the bottom. Pat it down evenly to form a crust.
Step 4: Add Filling Layer
Spoon the beef-bean-corn mixture evenly over the hashbrown base. Spread it out gently.
Step 5: Add Cheese
Sprinkle 2 cups shredded sharp cheddar cheese over the top of the beef mixture.
Step 6: Bake
Bake uncovered at 400°F for 25–30 minutes until cheese is melted and edges are bubbling.
Step 7: Add Toppings
Once out of the oven, top with 1 (14.5 oz) can drained diced tomatoes, 1 (2.25 oz) can sliced black olives, 1–2 sliced fresh jalapeños, 1/2 cup sour cream (in dollops), 1 cup shredded lettuce, and 2 tbsp chopped cilantro.
Leftovers & Storage
Store leftovers in an airtight container in the fridge for up to 4 days. Reheat in the oven at 350°F for 10–15 minutes or microwave individual portions. Add fresh toppings after reheating. Don’t freeze once toppings are added—freeze the casserole without them if needed.
Why This Recipe Works (Quick Science)
The hashbrowns crisp up as they bake because the moisture evaporates while the fat from the beef and cheese seeps down, helping them fry up golden brown. Layering the cheese on top creates a moisture barrier that seals in the filling while giving that crave-worthy melted finish.
Common Mistakes
- Using wet hashbrowns: Make sure they’re thawed and patted dry
- Not seasoning beef enough: The taco mix needs to coat the meat well
- Adding toppings too early: Lettuce and sour cream go on after baking
- Overbaking: Watch for bubbling edges and melty cheese, don’t let it dry out
What to Serve With
- A side of guacamole and tortilla chips
- Mexican rice or cilantro lime rice
- A cold lime agua fresca or a crisp Mexican lager
- Cornbread or jalapeño cheddar muffins
FAQ
Can I make it less spicy?
Yes! Use mild salsa and skip the fresh jalapeños.
Can I use tater tots instead of hashbrowns?
Absolutely. Just layer them on the bottom and reduce the bake time by 5–10 minutes.
Can I prep this ahead?
Yes, you can assemble it without toppings and bake it the next day.
Do I need to cook the hashbrowns first?
Nope! Thawing and pressing them into the dish is enough. They’ll crisp as they bake.
