Ingredients
- 1 lb (450 g) ground beef
- 4 to 5 medium russet potatoes, peeled and thinly sliced
- 1 tablespoon olive oil
- 1 small onion, finely diced
- 2 cloves garlic, minced
- 1 packet (about 1 oz / 28 g) taco seasoning
- 1 can (10 oz / 283 g) diced tomatoes with green chilies, drained
- 1 can (15 oz / 425 g) black beans, drained and rinsed (optional)
- 1 cup (240 ml) sour cream
- 1/2 cup (120 ml) milk
- 2 cups (200 g) shredded cheddar cheese, divided
- 1 cup (100 g) shredded Monterey Jack cheese
- 1 teaspoon chili powder, 1/2 teaspoon cumin, 1/2 teaspoon paprika
- Salt and black pepper, to taste
- Chopped cilantro, green onions, diced tomatoes, and sour cream, to serve
Step-by-Step Method
1. Heat the oven. Preheat to 375°F (190°C). Lightly grease a 9 x 13-inch (23 x 33 cm) baking dish.Oven on, dish greased
2. Cook the beef. Heat the oil in a large skillet over medium-high heat. Add the beef and cook for 5 to 6 minutes, breaking it into crumbles, until browned and no pink remains. Drain off excess fat.
3. Season the beef. Stir in the onion and cook for 3 minutes until soft. Add the garlic and cook for 30 seconds. Add the taco seasoning, chili powder, cumin, and paprika, and stir to coat. Add the tomatoes and beans, if using, simmer for 2 to 3 minutes, then season with salt and pepper.
4. Make the sauce. Whisk the sour cream and milk in a bowl until smooth, with a pinch of salt and pepper. This keeps the potatoes tender and adds a gentle tang.
5. Layer it up. Arrange half the potatoes in the dish, overlapping slightly. Top with half the beef, half the sour cream mixture, and half the cheddar. Repeat, then finish with the Monterey Jack on top.
6. Bake covered. Cover tightly with foil and bake for 40 to 45 minutes, until the potatoes are tender when pierced with a fork. The foil traps steam and cooks them evenly.
7. Bake uncovered. Remove the foil and bake for 10 to 15 minutes more, until the cheese is bubbly and lightly golden. Broil for 1 to 2 minutes at the end if you want a deeper golden top, watching closely
8. Rest and serve. Rest for 10 minutes so the layers set and slices hold together. Top with cilantro, green onions, tomatoes, and sour cream, and serve warm.
Tips for Best Results
- Slice thin and even: Aim for about 1/8 inch (3 mm). Even slices cook at the same rate.
- Drain the beef well: This keeps the casserole from turning greasy.
- Do not skip the foil: The covered bake is what makes the potatoes soft and tender.
- Let it rest: Ten minutes firms the layers and makes serving neater.
- Season in layers: Taste the beef after seasoning, and salt the potatoes lightly as you layer them.
Variations
- Add corn or peppers: Stir in 1 cup frozen corn or a diced bell pepper.
- Make it spicier: Use hot taco seasoning, add jalapeño, or serve with hot sauce.
- Try ground turkey: Swap the beef for turkey, cooked the same way.
- Add crunch: Sprinkle crushed tortilla chips over the cheese for the last 10 minutes.
- Make it extra creamy: Stir 4 oz (115 g) softened cream cheese into the sour cream mixture.
Storage / Make-Ahead / Reheating
Store leftovers in an airtight container in the fridge for up to 3 to 4 days. Reheat portions in the microwave for 1 to 2 minutes, or reheat the whole dish, covered with foil, in a 350°F (175°C) oven for 20 to 25 minutes. To make ahead, assemble up to 24 hours in advance, cover, and refrigerate, adding 10 minutes to the covered bake time. Freeze for up to 2 months; thaw overnight in the fridge before reheating.
FAQ
Can I use frozen potatoes?
Yes. Use thawed hash browns or frozen diced potatoes, pat them dry, and check for tenderness a little earlier.
Can I make this ahead?
Yes. Assemble the day before, cover, and refrigerate. Add about 10 minutes to the covered bake time.
Is it spicy?
It is mild to medium. Use mild seasoning and plain tomatoes for a kid-friendly version, or add jalapeño for more heat.
What should I serve with it?
A green salad, salsa, guacamole, and warm tortillas all work well. A fresh, crunchy side balances the rich casserole.
