Ingredients

Ingredient	Amount

Olive oil	1 tbsp
Onion, diced	1 small
Garlic, minced	3 cloves
Taco seasoning (sugar-free)	2 tbsp
Cream cheese	4 oz
Heavy cream or sour cream	1/2 cup
Shredded cheddar cheese	1 cup
Shredded Mexican blend cheese	1 cup
Diced tomatoes (drained)	1 cup
Jalapeños (optional)	to taste

Choosing the Best Ingredients

Use a good-quality 80/20 ground beef for juicy flavor—perfect for Low Carb Ground Beef Crockpot Recipes too. Choose full-fat dairy like cream cheese and heavy cream to keep your keto macros balanced. For spice lovers, toss in extra jalapeños or use pepper jack instead of cheddar. Want a smoky touch? Add a pinch of chipotle powder or smoked paprika.

Make sure your taco seasoning is no sugar added to keep this truly keto. Brands like Primal Palate or homemade blends work beautifully. If you prefer a lighter take, try swapping beef for ground turkey or chicken—it’s just as delicious!

How to Make Ultimate Cheesy Low-Carb Taco Casserole

1. Preheat oven to 375°F (190°C). Grease a 9×13″ baking dish.
2. Cook the beef: In a skillet, heat olive oil over medium heat. Add onion and garlic, cook until fragrant. Add ground beef and cook until browned, 6–8 minutes. Drain grease.
3. Season: Stir in taco seasoning and diced tomatoes. Simmer 2–3 minutes until thickened.
4. Add the creamy base: Mix in cream cheese and heavy cream until smooth and fully combined.
5. Assemble: Transfer mixture to the baking dish. Top evenly with shredded cheddar and Mexican blend cheeses.
6. Bake: Bake uncovered for 12–15 minutes, or until the cheese is bubbly and golden.
7. Finish: Garnish with cilantro or green onions and let rest 5 minutes before serving.

Pro Tips for the Perfect Texture

• Drain beef well before mixing—it keeps the casserole firm, not greasy.
• Use room-temp cream cheese so it melts evenly.
• Broil the top for 2 minutes for a crispy, bubbly cheese crust.
• Add crushed pork rinds on top before baking for a faux “taco shell” crunch.
