Key element — layer for texture
Spread half the chips on the bottom, add the seasoned beef and cheese, then top with remaining chips. This keeps some crunch while the bottom layer softens into the cheesy sauce.
Ingredients
Beef mixture
- 1½ lb (680g) lean ground beef (90/10 or 93/7)
- 1 medium onion, diced
- 2 garlic cloves, minced
- 2 Tbsp chili powder
- 1 tsp ground cumin
- 1 tsp smoked paprika
- ½ tsp salt + ¼ tsp black pepper
- ½ cup water or beef broth
Casserole
- 4–5 oz low-carb tortilla chips, pork rinds, or cheese crisps
- 2 cups shredded cheddar or Mexican blend cheese
- 4 oz cream cheese, softened (optional for extra creaminess)
Toppings
- ½ cup sour cream or Greek yogurt
- 1 large tomato, diced
- ¼ cup fresh cilantro, chopped
- Optional: sliced jalapeño, green onion, avocado
Swaps
- Turkey: Ground turkey works; add a little oil when browning.
- Spicier: Add diced jalapeño to the beef or extra cayenne.
- Extra protein: Stir an extra ½ cup shredded cheese into the beef mixture.
- Dairy-free: Use dairy-free cheese and sour cream alternatives.
Instructions
| 1 | Preheat and brown. Preheat oven to 375°F (190°C). In a large skillet over medium-high heat, cook the ground beef and onion until the beef is browned and the onion is soft, 6–8 minutes. Drain excess fat if needed. |
| 2 | Season. Stir in garlic, chili powder, cumin, paprika, salt, and pepper. Cook 30–60 seconds. Add water or broth and simmer 2–3 minutes until slightly thickened. Stir in softened cream cheese if using until smooth. |
| 3 | Layer. In a 9×13-inch baking dish, spread half the low-carb chips. Spoon the beef mixture evenly over the chips. Sprinkle with most of the shredded cheese. Top with remaining chips and the rest of the cheese. |
| 4 | Bake. Bake 12–15 minutes until the cheese is fully melted and bubbly and the edges are lightly golden. |
| 5 | Top and serve. Remove from the oven. Dollop with sour cream, scatter diced tomato and cilantro, and add any optional toppings. Serve immediately while hot and cheesy. |
Pro tips
- Use sturdy low-carb chips or pork rinds so they hold up under the beef and cheese.
- Do not over-bake — 12–15 minutes is enough to melt the cheese without drying the casserole.
- For extra creaminess, stir a few tablespoons of cream cheese into the beef before layering.
- Add fresh toppings only after baking so they stay cool and bright.
- Let the casserole rest 3–4 minutes before scooping so it holds together better.
