Ingredients Method

Ingredients

  

• 1.5 pounds ground beef (80/20 or 85/15)
• 1 tablespoon olive oil (if needed)
• 1 small yellow onion, diced
• 3 cloves garlic, minced
• 1 medium red bell pepper, diced
• 1 small jalapeño, minced (optional, seeds removed for less heat)
• 1 (14.5-ounce) can fire-roasted diced tomatoes, drained
• 1 (8-ounce) can tomato sauce (no sugar added)
• 1/3 cup canned diced green chiles
• 2 tablespoons chili powder
• 1 teaspoon ground cumin
• 1 teaspoon smoked paprika
• 1/2 teaspoon dried oregano
• 1/2 teaspoon onion powder
• 1/2 teaspoon garlic powder
• 1/2 teaspoon sea salt, plus more to taste
• 1/4 teaspoon black pepper
• 1 medium zucchini, thinly sliced into half-moons
• 2 cups riced cauliflower (fresh or frozen, thawed)
• 2 cups shredded cheese (Mexican blend or cheddar/Monterey Jack)
• 1/4 cup chopped fresh cilantro, plus more for serving
• 1/2 cup sour cream or plain Greek yogurt, for serving (optional)
• Lime wedges, for serving (optional)

Method

 

1. Preheat the oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish.
2. Warm a large skillet over medium heat. Add the ground beef and cook, breaking it up with a spatula, until browned and no longer pink, about 6–8 minutes. Drain excess fat if needed.
3. If the pan looks dry, add the olive oil. Stir in the onion, bell pepper, and jalapeño. Cook until softened, about 4–5 minutes. Add the garlic and cook 30 seconds, until fragrant.
4. Stir in the diced tomatoes, tomato sauce, green chiles, chili powder, cumin, smoked paprika, oregano, onion powder, garlic powder, salt, and black pepper. Reduce heat and simmer 5–7 minutes, letting the flavors meld. Taste and adjust seasoning.
5. Add the riced cauliflower to the skillet and fold it into the beef mixture. Cook 2–3 minutes to soften slightly and absorb some sauce. Remove from heat and stir in the chopped cilantro.
6. Spread half of the zucchini slices in the bottom of the baking dish. Spoon half of the beef mixture over the zucchini and spread evenly. Sprinkle with half of the shredded cheese.
7. Repeat the layers: remaining zucchini, remaining beef mixture, and the rest of the cheese.
8. Cover the dish loosely with foil and bake for 15 minutes. Remove the foil and bake another 10–12 minutes, until the cheese is melted and bubbling and the edges are slightly browned.
9. Let the casserole rest for 8–10 minutes before slicing. This helps it set and makes clean slices.
10. Top with extra cilantro. Serve with a dollop of sour cream or Greek yogurt and a squeeze of lime, if you like.

Why This is Good for You

• Lower carb load: Skipping tortillas and using zucchini and cauliflower keeps carbs in check while adding fiber.
• Protein-rich: Ground beef provides protein that keeps you full and supports muscle maintenance.
• Nutrient-dense veggies: Bell pepper, tomatoes, and zucchini bring vitamins A and C, potassium, and antioxidants.
• Balanced satisfaction: The combo of protein, fat, and fiber makes this dish filling without a carb crash.

Common Mistakes to Avoid

• Skipping the drain: Not draining beef fat can make the casserole oily. Drain or blot if your beef is very fatty.
• Watery bake: Zucchini and tomatoes release moisture.

  Drain the tomatoes and keep zucchini slices thin. Rest the casserole before cutting.

• Under-seasoning: Cauliflower rice is mild. Taste the sauce and adjust salt, chili powder, and cumin.
• Burned cheese: Cover for the first bake, then uncover to brown.

  This prevents dry or overcooked cheese.

• Overcooking the veggies: They’ll soften in the oven. Sauté just until tender, not mushy.

Variations You Can Try

• Chicken or turkey: Swap ground beef for ground chicken or turkey for a leaner option. Add a splash of broth if it seems dry.
• Poblano layers: Roast, peel, and slice poblanos, then layer them in place of zucchini for a deeper, roasted flavor.
• Keto-friendly tortillas: Use low-carb tortillas cut into quarters as layers if you want a more classic enchilada texture.
• Extra veg: Add sautéed mushrooms or spinach to the beef mixture for more fiber and volume.
• Cheese swap: Try pepper jack for a little heat or a blend of cheddar and Oaxaca for great melt.
• Red or green: Use a low-carb green enchilada sauce instead of tomato sauce for a tangy, herby twist.

FAQ

How many carbs are in a serving?

Exact numbers depend on your ingredients and serving size, but a typical portion lands in the low-carb range, often around 6–10 net carbs per serving.

Use a nutrition calculator with your brands and amounts for precise info.

Can I make this ahead?

Yes. Assemble the casserole up to the baking step, cover, and refrigerate for up to 24 hours. Add 5–10 extra minutes to the bake time if going straight from the fridge.

What’s the best way to keep it from getting soggy?

Drain the tomatoes well, slice zucchini thin, and let the finished casserole rest before serving.

If your zucchini is very watery, sprinkle lightly with salt and pat dry before layering.

Can I make it dairy-free?

Use a dairy-free shredded cheese alternative that melts well and swap sour cream for dairy-free yogurt. Check labels to keep carbs low.

Is this spicy?

It’s mild to medium as written. For less heat, skip the jalapeño and use mild green chiles.

For more heat, add cayenne or use hot chili powder.

Can I use store-bought enchilada sauce?

Yes, but choose a low-sugar brand to keep it low carb. Replace the tomato sauce and some spices with about 1.5 cups of your preferred sauce, then adjust seasoning to taste.

What can I serve with it?

Try a simple side salad with avocado, a quick slaw with lime, or roasted green beans. Cauliflower rice also pairs well if you want extra volume without more carbs.
