Ingredients You’ll Need

- 1 package taco seasoning: This brings all the classic taco flavors to your beef. You can also use homemade seasoning for a personalized touch.
- 1 teaspoon garlic powder: Adds a fragrant depth to the beef. Fresh garlic works too—use 2 cloves, minced.
- 10-ounce can Rotel tomatoes (drained): These diced tomatoes with green chilies add a zesty kick. Feel free to use fresh tomatoes if you prefer.
- 2 pounds russet potatoes (peeled and thinly sliced): These provide the hearty base of your casserole. Yukon gold potatoes can be a delightful alternative.
- 1 ½ cups cheddar cheese (shredded): Cheddar melts beautifully and provides that gooey texture. To mix it up, consider using a Mexican blend cheese.
- ½ cup water: This helps create steam inside the slow cooker, ensuring the potatoes cook tender.
- 1 teaspoon salt and 1 teaspoon black pepper: Essential seasoning for well-balanced flavor.
- 1 cup sour cream: This adds creaminess and richness. You can use plain Greek yogurt for a healthier option.
- Oil or nonstick cooking spray for greasing: Prevents sticking and makes cleanup easier.
- Sour cream, fresh tomatoes, shredded cheddar or Mexican blend cheese, cilantro, avocado, jalapenos: These optional toppings allow for personalization based on your family’s favorites!
How to Make Slow Cooker Beef Taco Casserole
- Brown the Ground Beef: In a large skillet over medium-high heat, add the 2 pounds ground beef. Season with 1 teaspoon salt, 1 teaspoon black pepper, and 1 teaspoon garlic powder. Cook until browned, about 5-7 minutes. Drain off any excess grease.
- Season the Beef: Stir in ½ cup water and the package of taco seasoning into the cooked ground beef. Let it simmer for 2-3 minutes until slightly thickened, stirring occasionally.
- Combine with Tomatoes and Sour Cream: Gently fold in the 10-ounce can of drained Rotel tomatoes and 1 cup sour cream into the beef mixture until uniform.
- Layer in the Slow Cooker: Lightly grease your slow cooker with oil or nonstick cooking spray. Start by adding a layer of thinly sliced potatoes (2 pounds) at the bottom.
- Add Beef Mixture: Spoon a layer of the taco beef mixture over the potatoes, spreading it out evenly.
- Cheese It Up: Sprinkle a layer of 1 ½ cups shredded cheddar cheese over the beef. Repeat these layers (potatoes, beef, cheese) until all ingredients are used, finishing with a layer of cheese.
- Cook: Cover and cook on low for 5-6 hours or high for 3-4 hours. The casserole should be fork-tender when ready.
- Let it Rest: Once finished cooking, let the casserole sit for 10 minutes before serving. This helps it set slightly for easier serving.
Storing & Reheating
Store any leftovers in an airtight container in the refrigerator for up to 3 days. For longer storage, transfer to a freezer-safe container and freeze for up to 3 months. When you’re ready to enjoy it again, reheat in the microwave or oven at 350°F (175°C) until warmed through, about 20 minutes. Keep in mind that freezing may change the texture slightly, but adding a dollop of sour cream can restore some of that creaminess.

Chef’s Helpful Tips
- Avoid greasy beef: Make sure to drain excess fat after browning your meat. This step keeps the casserole from becoming too oily.
- Layer wisely: Ensure potatoes cover the entire bottom to promote even cooking.
- Customize your toppings: Get creative! Top with sliced avocados, chopped cilantro, or fresh jalapenos to add freshness and bite.
- Make-Ahead Option: Prepare the beef and potato layers ahead of time and refrigerate overnight. Cook in the morning for easier meal planning.
- Check Potatoes: If they are on the thicker side, cooking times may vary. Always check the potatoes for fork-tenderness.
