Why You’ll Love This Recipe
This casserole is a favorite for anyone following a low-carb or keto lifestyle, but it’s also a hit with the whole family.
- Low carb & keto-friendly: No pasta, rice, or tortillas needed
- Easy prep: Simple ingredients and minimal hands-on time
- Rich and filling: Creamy, cheesy layers with seasoned beef
- Great for leftovers: Reheats beautifully for quick meals
Ingredients
- 2 pounds lean ground beef
- ½ cup diced onion
- 4 tbsp Homemade Taco Seasoning mix or 2 packets of store-bought seasoning
- 2 cans of tomatoes with green chilis
- 8 oz cream cheese
- 1 cup shredded cheese
Instructions
- In a large skillet over medium heat, brown the ground beef. Add the diced onion and cook for a few more minutes until softened. Drain any excess grease.
- Stir in the taco seasoning and tomatoes with green chilis. Let the mixture simmer until most of the liquid has been absorbed.
- Prepare your slow cooker by using a liner for easy cleanup or spraying it with non-stick spray.
- Layer half of the meat mixture into the bottom of the slow cooker. Slice the cream cheese and place half of it over the meat, then sprinkle with ½ cup of shredded cheese.
- Repeat the layers with the remaining meat, cream cheese, and shredded cheese.
- Cover and cook on low for 3–4 hours or on high for 2 hours, until the casserole is hot, melted, and bubbling.
Tips & Variations
- Make it spicier: Add diced jalapeños or extra chili flakes
- Swap the protein: Ground turkey works well as a lighter option
- Boost the flavor: Add garlic or a pinch of cumin while browning the meat
- Add toppings: Serve with sour cream, avocado, or green onions
Serving Ideas
Enjoy this casserole on its own for a low-carb meal, or pair it with a simple side salad. If you’re not strictly low-carb, it also tastes great served over rice, cauliflower rice, or wrapped in low-carb tortillas.
Storage & Reheating
Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave or oven until warmed through. This casserole can also be frozen for up to 2 months—just thaw and reheat when ready to enjoy.
You can make this casserole in the oven instead of a Crockpot. Just preheat the oven to 350°F and spray a 9×13 casserole dish with non-stick spray. Bake for 20-30 minutes until heated through, and the cheese begins to brown.
