  • Total Time: 45-50 minutes
  • Yield: 6 servings 1x

Ingredients

Scale

1 pound (about 450 g) breakfast sausage or ground pork
12 large eggs
2 cups (about 200 g) shredded cheddar cheese
3/4 cup (180 ml) heavy whipping cream
1/2 cup (120 g) sour cream or plain whole milk Greek yogurt
1 tablespoon hot sauce
1/2 cup (75 g) diced onion
1/2 cup (75 g) diced bell peppers or other low-carb vegetables
Salt and pepper to taste
2 tablespoons sliced green onions for garnish

Instructions

1. Preheat oven to 350°F (175°C). Grease a 9×13-inch casserole dish or muffin pan if making muffins.

2. Heat a large skillet over medium-high heat, add sausage or ground pork, and break apart with a spoon. Cook until no longer pink, about 5–7 minutes. Drain excess grease if needed.

3. If using, sauté diced onion and bell peppers until softened, about 4–5 minutes, and set aside.

4. In a large bowl, whisk together eggs, heavy cream, sour cream, hot sauce, shredded cheese, salt, and pepper until smooth and well combined.

5. Add cooked sausage and sautéed vegetables (if using) to the egg mixture and stir gently to combine.

6. Pour the mixture evenly into the prepared casserole dish or muffin tins.

7. Bake casserole for 30–40 minutes or muffins for 25–30 minutes, until firm and cooked through. A knife or toothpick inserted into the center should come out clean.

8. Remove from oven, allow to cool slightly. Garnish with green onions if desired, and serve warm.

Notes

🥚 Use room temperature eggs and heavy cream for better texture and mixing.
🕒 Avoid overbaking to keep the casserole moist and slightly custardy inside.
🧀 Customize with different cheeses or meats to suit taste and dietary needs, including dairy-free options using coconut cream and vegan cheese alternatives.
