Difficulty Level
Easy: A straightforward recipe designed for cooks of all skill levels with minimal hands-on time.
Ingredients
- 8 large eggs, whisked
- 1 cup heavy cream
- 1 pound sausage (pork or turkey), crumbled and cooked
- 1 cup shredded cheddar cheese
- 1 cup shredded mozzarella cheese
- 1 small onion, finely diced
- 1 cup chopped bell peppers (use mixes of red, yellow, and green for color)
- 2 cups fresh spinach, roughly chopped
- 3 cloves garlic, minced
- 1 teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon smoked paprika
- 2 tablespoons olive oil or avocado oil, for sautéing
- Optional: sliced mushrooms, jalapeños, or your favorite low-carb veggies
Instructions
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter or nonstick spray.
- Cook the sausage: Heat olive oil in a large skillet over medium heat. Add crumbled sausage and cook until browned, about 5-7 minutes. Transfer cooked sausage to a bowl, leaving some drippings in the skillet.
- Sauté the veggies: In the same skillet, add diced onion, bell peppers, and minced garlic. Sauté until vegetables are soft and fragrant, about 5 minutes. Stir in spinach and cook until wilted. Remove from heat and mix veggies with the sausage.
- Whisk the eggs: In a large mixing bowl,combine eggs,heavy cream,salt,pepper,and smoked paprika. Whisk until pale and well blended.
- Assemble the casserole: Spread the sausage and veggie mixture evenly on the bottom of the prepared baking dish. Sprinkle the shredded cheddar and mozzarella cheeses evenly over the mixture. Pour the egg and cream mixture slowly over all, ensuring it is evenly distributed.
- Bake: Place the casserole in the oven and bake for 35-40 minutes, or until the eggs are set and the top is golden brown. A toothpick inserted into the center should come out clean.
- Rest and serve: Let the casserole cool for 5-10 minutes before slicing.This allows the dish to firm up, making serving easier and neater.
Tips for Success
- Add texture: Toasted nuts like pecans or walnuts sprinkled on top before baking provide a delightful crunch.
- make it your own: Swap sausage for bacon or ham,or use a mix of cheeses such as gouda or feta for unique flavor twists.
- Prevent sogginess: Drain any excess liquid from vegetables beforehand, especially if using mushrooms or zucchini.
- Make ahead: Prepare the casserole the night before, cover tightly, and refrigerate. Bake fresh in the morning for effortless weekday breakfasts.
- Use fresh herbs: Sprinkle chopped parsley, chives, or basil on top right before serving for a burst of color and freshness.
Serving Suggestions and Storage Hacks
Serve slices warm with a crisp side salad or sautéed greens for a complete, nutrient-dense breakfast. Garnish with sliced avocado or a dollop of sour cream to enhance creaminess. For added zest, a drizzle of hot sauce or homemade keto-friendly salsa pairs beautifully.
Storage is simple: cover leftovers tightly in the baking dish with foil or transfer to airtight containers. Refrigerate for up to 4 days or freeze individual portions for up to a month. Reheat gently in the microwave or oven to preserve texture and flavor.
