Instructions
-
Preheat oven to 375°F (190°C). Lightly grease a 9-inch oven-safe skillet or baking dish with 1 tablespoon of olive oil.

Heat remaining 1 tablespoon olive oil over medium heat in the skillet. Add chopped onion and minced garlic; sauté until translucent and aromatic, about 3 minutes.

Add cauliflower florets to the skillet and cook for 5-7 minutes, stirring occasionally, until cauliflower softens slightly.

In a large bowl, whisk together eggs, heavy cream, salt, black pepper, smoked paprika, and dried thyme until well blended.
-
Fold in shredded cheddar and grated Parmesan cheese.
-
Add the cooked cauliflower, spinach, onion, and garlic mixture to the egg mixture and gently combine all ingredients.
-
Pour the mixture evenly into the prepared skillet or baking dish.
-
Bake for 20-25 minutes or as needed until the center is set and reaches 160 F (71 C) on a food thermometer.
-
Remove from oven and allow to cool for 5 minutes before slicing.
-
Optional: Garnish with fresh parsley or chives.
-
Serve warm after the 5-minute rest.
