Each serving delivers 23g of protein with just 4g of carbs — zero compromise on flavor. It's gluten-free, vegetarian, and endlessly customizable.

Ingredients

• 8 large eggs
• 200g shredded cheddar cheese
• 200g cottage cheese (full-fat)
• 120ml whole milk (or heavy cream for extra richness)
• 1 red bell pepper, diced
• 1 medium onion, diced
• 100g baby spinach
• 1 tsp garlic powder
• 1 tsp dried oregano
• 1/2 tsp smoked paprika
• 1/2 tsp salt
• 1/4 tsp black pepper
• 1 tbsp olive oil
• 50g shredded mozzarella (for topping)

Instructions

1. Preheat oven to 190°C (375°F). Grease a 9x13 inch (23x33cm) baking dish with olive oil.
2. Heat olive oil in a skillet over medium heat. Add onion and bell pepper. Cook 5 minutes until softened. Add spinach and cook 2 minutes until wilted. Remove from heat.
3. In a large bowl, whisk eggs, milk, cottage cheese, garlic powder, oregano, smoked paprika, salt, and pepper until well combined.
4. Stir in cheddar cheese and the cooked vegetable mixture.
5. Pour into the prepared baking dish. Sprinkle mozzarella evenly over the top.
6. Bake for 30-35 minutes until the center is set and the top is golden. A knife inserted in the center should come out clean.
7. Let rest 5 minutes before slicing into 6 portions. Serve warm.

Tips & Variations

• Add 150g cooked crumbled sausage or diced ham to boost protein further.
• Swap cheddar for Gruyere or pepper jack for a flavor variation.
• Use heavy cream instead of whole milk for an even richer, more keto-friendly version.
• Make ahead: bake Sunday, slice, and refrigerate in containers. Microwave 90 seconds per serving.
• Frozen portions reheat well — wrap individually and freeze for up to 2 months.
