Ingredients You’ll Need

  • 2 pounds ground beef (80/20): This blend offers a perfect fat-to-lean ratio, giving your casserole rich flavor. You can substitute turkey for a leaner option.
  • 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

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. Add Beef Mixture: Spoon a layer of the taco beef mixture over the potatoes, spreading it out evenly.
  6. 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.
  7. Cook: Cover and cook on low for 5-6 hours or high for 3-4 hours. The casserole should be fork-tender when ready.
  8. 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.
