For the casserole

• 1½ lb (680 g) ground beef
• 1 small onion, diced
• 2 cloves garlic, minced
• 1 bell pepper, diced
• 1 (10-oz/283 g) can diced tomatoes with green chilies, drained
• ¾ cup (180 g) low-carb salsa
• 2 tbsp taco seasoning
• 4 oz (113 g) cream cheese, softened
• 1 cup (100 g) shredded cheddar cheese
• 1 cup (100 g) shredded Monterey Jack or Mexican-blend cheese
• ½ tsp salt, or to taste

• Sour cream
• Chopped cilantro
• Diced tomatoes

Instructions

1. Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch (23×33 cm) baking dish.
2. Brown the beef: Heat a large skillet over medium-high heat. Add the ground beef and cook for about 6–8 minutes, breaking it apart as it cooks. Drain excess grease if necessary.
3. Add the vegetables: Add the onion and bell pepper. Cook for 3–4 minutes, then add the minced garlic and cook for another 30 seconds.
4. Season: Stir in the taco seasoning, salt, and black pepper.
5. Build the filling: Add the drained tomatoes, salsa, and cream cheese. Stir until the cream cheese melts and everything is well combined. Simmer for 2–3 minutes.
6. Transfer to the dish: Spread the beef mixture evenly into the prepared baking dish.
7. Add cheese: Sprinkle the cheddar and Monterey Jack evenly over the top.
8. Bake: Bake uncovered for 15–20 minutes, or until the cheese is melted, bubbling, and lightly golden.
9. Rest and serve: Let the casserole rest for 5 minutes. Add your favorite low-carb toppings and serve warm.

Notes

• Use 90–93% lean ground beef if you prefer a lighter casserole.
• Check the carbohydrate content of your salsa and taco seasoning, as brands vary.
• For an even lower-carb version, use a homemade taco seasoning without added sugar or starch.
• You can substitute ground turkey or ground chicken for the beef.
• Leftovers can be refrigerated in an airtight container for 3–4 days.
• Reheat individual portions in the microwave or oven until hot.

Tips for the Best Casserole

🔥 Brown the beef well: Browning creates more flavor than simply simmering the meat.

🧀 Use two cheeses: Cheddar gives a sharp flavor while Monterey Jack melts beautifully.

🌶️ Adjust the heat: Add jalapeños, cayenne, or hot salsa for extra spice.

🥑 Finish with fresh toppings: Avocado, cilantro, lime, and sour cream add freshness and contrast to the rich casserole.

💧 Don’t overdo the salsa: Too much liquid can make the casserole watery. Drain canned tomatoes thoroughly.

Potential Benefits

• High in protein: Ground beef and cheese provide substantial protein to help support muscle maintenance and satiety.
• Lower in carbohydrates: Replacing taco shells or tortillas with vegetables and a cheesy beef filling reduces the carbohydrate load.
• Customizable vegetables: Bell peppers, tomatoes, avocado, and other toppings can add vitamins, minerals, and fiber.
• Satisfying: The combination of protein, fat, and cheese can make a relatively small portion quite filling.

Q&A

Q: Can I make this casserole keto-friendly?
Yes. Choose a very low-carb salsa and taco seasoning, watch the portion of onions and tomatoes, and use keto-friendly toppings.

Q: Can I use ground chicken instead of beef?
Absolutely. Ground chicken or turkey works well. Because they are leaner, you may want to add a little olive oil or extra cheese for moisture.

Q: Can I prepare it ahead of time?
Yes. Assemble the casserole, cover it, and refrigerate it for up to 24 hours. Bake when ready, allowing a few extra minutes if it goes directly from the refrigerator to the oven.

Q: Can I freeze Low-Carb Taco Casserole?
Yes. Cool it completely, portion it into freezer-safe containers, and freeze. Thaw overnight in the refrigerator before reheating for the best texture.

Q: What can I serve with it?
Try a simple green salad, cauliflower rice, roasted zucchini, avocado, or steamed vegetables.

Q: How can I make it spicier?
Use hot salsa, diced jalapeños, cayenne pepper, or a few dashes of your favorite hot sauce.

Q: Can I make it without cream cheese?
Yes. You can omit it for a less creamy casserole, or replace it with a small amount of sour cream or additional shredded cheese.

Q: How do I keep it from becoming watery?
Drain canned tomatoes well and avoid adding excessive salsa. Let the cooked filling simmer for a few minutes before transferring it to the baking dish.
