Ingredients
- 1 ½ lbs (680 g) lean ground beef
- 1 large onion, chopped
- 2 cloves garlic, minced
- 1 packet (1 oz / 28 g) taco seasoning mix
- 1 cup (240 ml) beef broth
- 1 (14.5 oz / 411 g) can diced tomatoes, undrained
- 2 lbs (900 g) russet or Yukon Gold potatoes, peeled and cut into ½-inch (1.2 cm) cubes
- 1 (4 oz / 113 g) can chopped green chiles, undrained (mild or hot, to taste)
- 1 ½ cups (170 g) shredded Monterey Jack or cheddar cheese, divided
- Optional toppings: sour cream, salsa, guacamole, fresh cilantro, crushed tortilla chips
Ingredient Notes
- Ground Beef: Using lean ground beef (85-90%) helps minimize excess grease in your casserole. If you use a higher fat content, be sure to drain the fat thoroughly after browning.
- Potatoes: Russet or Yukon Gold potatoes work best here as they become wonderfully tender and absorb the flavors well. Cut them into even ½-inch cubes to ensure they cook consistently.
- Taco Seasoning: A standard store-bought packet is convenient, but you can also make your own blend using chili powder, cumin, paprika, onion powder, garlic powder, and a pinch of cayenne for extra heat.
- Green Chiles: These add a mild, tangy flavor without much heat. If you prefer more spice, opt for hot green chiles or add a dash of your favorite hot sauce.
- Cheese: Monterey Jack melts beautifully and adds a creamy texture, while cheddar offers a sharper flavor. A blend of both is also delicious.
Equipment You’ll Need
- 6-quart (5.7 L) slow cooker
- Large skillet
- Cutting board and knife
How to Make Slow Cooker Beefy Potato Taco Casserole
Making this hearty casserole is incredibly simple. Just follow these easy steps for a delicious, satisfying meal.
Step 1: Brown the Beef and Aromatics
Heat a large skillet over medium-high heat. Add the ground beef and cook, breaking it apart with a spoon, until it’s completely browned. Drain any excess grease. Add the chopped onion and cook for 3-5 minutes until softened. Stir in the minced garlic and taco seasoning, cooking for another minute until fragrant. Remove from heat.
Step 2: Layer the Ingredients in the Slow Cooker
Place half of the cubed potatoes evenly in the bottom of your 6-quart slow cooker. Spoon half of the browned beef mixture over the potatoes. Scatter half of the diced tomatoes and green chiles over the beef layer. Repeat these layers with the remaining potatoes, beef mixture, diced tomatoes, and green chiles.
Step 3: Add Liquid and Cook
Pour the beef broth evenly over the layered ingredients in the slow cooker. Cover and cook on LOW for 6-8 hours or on HIGH for 3-4 hours, or until the potatoes are fork-tender. Cooking times can vary slightly depending on your slow cooker model.
Step 4: Add Cheese and Serve
About 30 minutes before serving, sprinkle 1 cup of the shredded cheese evenly over the top of the casserole. Replace the lid and continue cooking until the cheese is melted and bubbly. Once melted, turn off the slow cooker. Let the casserole rest for 5-10 minutes before serving. Garnish with the remaining ½ cup of shredded cheese and any desired toppings.
Pro Tips for the Best Results
- Brown the Beef Thoroughly: Don’t skip browning the beef! This step adds depth of flavor and improves the texture of the meat in the final casserole.
- Cut Potatoes Evenly: Uniformly sized potato cubes ensure that all potatoes cook through at the same rate, preventing some from being undercooked while others are mushy.
- Don’t Overfill: Make sure your slow cooker isn’t packed too tightly, as this can impede even cooking and lead to liquid overflowing.
- Add Cheese Towards the End: Adding the cheese in the last 30 minutes prevents it from becoming rubbery or burnt, ensuring a perfectly melted, gooey topping.
- Season to Taste: Taste the beef mixture after browning and before layering. Adjust seasoning if needed, keeping in mind the taco seasoning will provide the primary flavor.
Common Mistakes to Avoid
- Undercooked Potatoes: This is often due to large or unevenly cut potato pieces, or not enough cooking time. Ensure potatoes are cut to size and cooked until truly fork-tender.
- Greasy Casserole: If using high-fat ground beef, failing to drain the fat after browning can result in a greasy final dish. Always drain the fat well.
- Bland Flavor: Not browning the beef or not using enough seasoning can lead to a less flavorful casserole. Don’t be shy with the taco seasoning!
- Dry Casserole: While this recipe includes broth, make sure your slow cooker lid is sealed properly to retain moisture.
Variations & Substitutions
- Protein Swaps: You can easily substitute ground turkey or ground chicken for the ground beef. Adjust cooking time slightly if needed.
- Add More Veggies: Feel free to toss in a can of drained black beans, corn kernels (frozen or canned), or diced bell peppers along with the other layers for extra nutrition and flavor.
- Spice It Up: For a spicier kick, add a pinch of cayenne pepper, a few dashes of hot sauce, or use a hot taco seasoning mix.
- Cheese Choices: Experiment with different shredded cheeses like Colby Jack, Pepper Jack (for a kick), or a Mexican cheese blend.
- Different Toppings: Beyond traditional taco toppings, consider crushed Fritos, pickled jalapeños, or a drizzle of ranch dressing.
Serving Suggestions

- Reheating Method:
- Microwave: For individual portions, microwave on high in 1-minute intervals, stirring occasionally, until heated through.
- Oven: For larger portions, transfer to an oven-safe dish, cover with foil, and bake at 350°F (175°C) for 20-30 minutes, or until heated thoroughly.

FAQ
Can I make this casserole ahead of time?
Yes, you can prepare the beef and onion mixture the day before and store it in the refrigerator. Assemble the casserole in the slow cooker just before cooking. You can also cook the entire casserole and reheat it; it tastes great the next day!
Can I use frozen potatoes?
While fresh potatoes are recommended for the best texture, you can use frozen diced potatoes. They may cook a bit faster, so keep an eye on them to avoid them becoming too soft.
What if I don’t have beef broth?
Chicken broth or vegetable broth can be used as a substitute for beef broth. Water with a bouillon cube dissolved in it would also work in a pinch.
How do I know when the potatoes are done?
The potatoes are done when they are easily pierced with a fork. They should be tender, but not mushy.
Can I make this vegetarian?
Absolutely! Replace the ground beef with an equal amount of cooked lentils, black beans, or a plant-based ground meat alternative. Ensure you still use vegetable broth for the liquid.
Is this casserole spicy?
This recipe uses mild taco seasoning and canned green chiles, which typically provide a very mild spice level. You can easily adjust the heat by choosing hot taco seasoning, hot green chiles, or adding a pinch of cayenne pepper.
