FULL INSTRUCTIONS WITH STEPS FOR BASIC BAKED FRITTATA

First Step: Prep Ingredients and Dish

Gather all your ingredients: fresh spinach, sausage, shredded cheddar, eggs, heavy cream, salt, pepper, and oil or butter. Preheat the oven to 375°Fahrenheit (190°Celsius) so it’s ready when your frittata is assembled. Lightly grease a 9×9-inch baking dish to prevent sticking and make cleanup easier.

Second Step: Cook the Sausage

Heat a skillet over medium heat and cook the sausage until browned and crumbly. Stir occasionally to break up any large pieces and ensure even cooking. Drain off excess grease to keep the casserole light and flavorful.

Third Step: Layer the Frittata

Spread the cooked sausage evenly across the bottom of the greased baking dish. Sprinkle the chopped spinach over the sausage to create a fresh, colorful layer. This forms a tasty base for the egg mixture to soak into.

Fourth Step: Add Sauce and Bake

In a bowl, whisk together the eggs, heavy cream, salt, and pepper until smooth. Pour the mixture over the sausage and spinach, then sprinkle shredded cheddar on top for a cheesy finish. Bake in the preheated oven for 25–30 minutes until the eggs are set and the cheese is golden, then let it cool slightly before serving.

TRICKS AND TIPS:

  • Use good-quality sausage for the best flavor. Cooking it thoroughly before adding to the frittata ensures every bite is savory and well-seasoned.
  • Fresh spinach makes a big difference in taste and texture. Make sure to wash and dry it well before adding to avoid extra moisture in the frittata.
  • Beat the eggs until smooth for a fluffy texture. Adding a splash of milk or cream can make the frittata even richer and creamier.
  • Let the frittata rest for a few minutes after baking. This helps it set properly and makes it easier to cut into perfect slices for serving.
