Preheat oven to 350°F (175°C) and lightly grease an 11×7-inch baking dish with cooking spray.
In a skillet over medium-high heat, warm olive oil and cook ground beef until browned and crumbly, about 5–7 minutes. Season with half of the chili powder, onion powder, garlic powder, plus cumin, coriander, salt, and pepper. Stir for 4–5 minutes until fragrant, then remove from heat.
Stir in eggs, heavy cream, chopped onion, tomato paste, and riced cauliflower until well combined. Transfer mixture into the prepared baking dish.
Sprinkle half of the Cheddar cheese over the top.
Bake for 25–30 minutes, then add the remaining cheese and bake another 5 minutes until melted and golden.
Let rest 5 minutes before serving.

Substitute ground turkey for beef if desired.

Full-fat coconut cream or an extra egg yolk can replace heavy cream.

Add vegetables like bell peppers or zucchini for variety.

Pulse cauliflower florets in a food processor if you don’t have riced cauliflower.

Make spicier by adding jalapeños, green chiles, or extra chili powder.
