Why you'll love this taco casserole
- All the taco layers, just 6g net carbs per serving

Health notes
- No tortillas: The carb-heavy layer is simply gone — you won't miss it.
- Homemade seasoning: Store taco packets often hide sugar and starch; the homemade blend has none.
- Beef & cheese: Big protein to keep you full for hours.
- Fresh toppings: Tomato, cabbage, olives and jalapeño bring crunch and fibre for almost no carbs.
- Estimated macros: No nutrition card came with this one, so values are estimated and kept consistent throughout.
Key element — bake it hot, top it cold
Bake just the beef, creamy layer and cheese. Then rest it 10 minutes and pile the fresh toppings on after. Hot cabbage and warm tomato go soggy fast — cold toppings over the hot, cheesy base give you that crisp, fresh contrast in the photo.
Ingredients
Taco beef
- 2 lbs ground beef (80–85% lean)
- 1 small onion, finely diced
- 2 cloves garlic, minced
- 2 Tbsp chili powder
- 2 tsp ground cumin
- 1 tsp smoked paprika
- 1 tsp salt
- ½ tsp black pepper
- ½ tsp dried oregano
- ½ cup sugar-free salsa
- 2 Tbsp water
Creamy layer & cheese
- 8 oz cream cheese, softened
- ½ cup sour cream
- 2 cups shredded Mexican blend cheese (or cheddar + Monterey Jack)
Fresh toppings (after baking)
- 2 cups shredded cabbage or iceberg lettuce
- 1 cup diced tomatoes
- ½ cup sliced black olives
- 1–2 jalapeños, sliced
- ¼ cup fresh cilantro leaves
- ¼ cup shredded cheddar, to finish
Swaps
- Turkey: Ground turkey or chicken works the same; add 1 Tbsp olive oil when browning.
- Spicier: Add ½ tsp cayenne to the seasoning and extra jalapeño on top.
- Dairy-light: Use Greek yogurt in place of sour cream.
- Serve it: Spoon into lettuce cups, over cauliflower rice, or with low-carb tortilla chips.
Instructions
| 1 | Brown the beef. Heat the oven to 375°F. Brown the ground beef and onion in a large skillet over medium-high heat, crumbling well, 7–8 minutes, until no pink remains. Drain off the excess fat. |
| 2 | Season it. Stir in the garlic, chili powder, cumin, paprika, salt, pepper and oregano for 30 seconds. Add the salsa and water and simmer 2–3 minutes until thick, not soupy. |
| 3 | Fill the dish. Spread the beef in a 9×13-inch baking dish. Beat the cream cheese and sour cream together and dot/spread it over the beef in an even layer. |
| 4 | Cheese and bake. Sprinkle the shredded cheese over the top. Bake 20–25 minutes until bubbling at the edges and golden in spots. |
| 5 | Rest it. Rest the casserole for 10 minutes. This sets the creamy layer so slices hold together, like the cut corner in the photo. |
| 6 | Top it cold. Scatter the cabbage, tomatoes, olives, jalapeño, cilantro and finishing cheddar over the top. Serve straight from the dish. |
Pro tips
- Drain the beef well — a greasy base makes a soupy casserole.
- Simmer the seasoned beef until thick before it goes in the dish.
- Soften the cream cheese properly or the creamy layer won't spread.
- Rest before topping and slicing — 10 minutes changes everything.
- Toppings go on cold, at the table if you can.
