- 1 small head cauliflower, chopped into small florets (about 3 cups)
- 3 cups fresh spinach leaves, roughly chopped
- 8 large eggs
- 1/2 cup shredded sharp cheddar cheese

- 1/3 cup heavy cream

- 1/4 tsp smoked paprika

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.

Add the chopped spinach, and cook until just wilted, about 2 minutes. Remove skillet from heat.
-
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 uncovered for 20-25 minutes, or until the frittata is set in the center and golden on top. A toothpick inserted in the center should come out clean.
-
Remove from oven and allow to cool for 5 minutes before slicing.

Optional: Garnish with fresh parsley or chives.
-
Serve warm as a nutritious, keto-friendly breakfast or a satisfying post-workout meal.
