Preheat your oven to 375°F and allow it to reach temperature before starting. In a medium bowl, whisk together the eggs, milk, salt, pepper, garlic powder, and paprika until well combined and slightly frothy.

Heat 2 tablespoons of butter in a 10-inch oven-safe skillet over medium heat. Once the butter foams, add your diced onions and potatoes, sautéing for 5-7 minutes until the potatoes begin to soften slightly.

Add the diced bell peppers and fresh spinach to the skillet, stirring frequently for 2-3 minutes until the spinach wilts down. The vegetables should be fragrant and starting to caramelize at the edges when you proceed to the next step.

Pour the egg mixture directly over the cooked vegetables, gently stirring to distribute everything evenly throughout the skillet. Sprinkle the shredded cheddar cheese and diced smoked turkey across the top, then cook the cozy breakfast frittata recipe on the stovetop for 2 minutes without stirring.

Transfer the skillet to your preheated oven and bake for 20-25 minutes until the eggs are set but still slightly jiggly in the very center. The top should turn golden brown and smell absolutely irresistible when done.

Remove from the oven and let it rest for 3-5 minutes before slicing. This allows the eggs to set completely and makes portioning much easier for your weekend brunch.

Garnish with fresh chives and serve warm directly from the skillet for maximum cozy appeal. The presentation matters when you're creating a heartwarming weekend brunch experience.
