How to Make Low-Carb Sausage Montgomery Bake

1. Prepare the oven: Preheat your oven to 350°F (175°C). Lightly grease an 8-inch square baking dish.
2. Cook the sausage: Brown the breakfast sausage in a large skillet over medium heat, breaking it into small crumbles. Drain any excess grease.
3. Mix the ingredients: Whisk the eggs in a large bowl. Add the cottage cheese, cooked sausage, and 1½ cups of shredded cheddar. Stir until everything is evenly combined.
4. Fill the baking dish: Pour the mixture into the prepared casserole dish and spread it evenly. Sprinkle the remaining ½ cup of cheddar cheese over the top.
5. Bake until golden: Bake for 30–35 minutes, or until the eggs are completely set and the cheese is melted and lightly golden around the edges.
6. Rest and serve: Allow the casserole to rest for 5–10 minutes before cutting it into squares. Serve warm.

Helpful Tips and Variations

• Add onions: Mix in finely chopped sautéed onions for extra flavor and a touch of natural sweetness.
• Try different cheeses: Monterey Jack, Colby, or pepper Jack are delicious alternatives to cheddar.
• Prepare ahead: Brown the sausage the day before and refrigerate it in an airtight container to save time.
• Make individual portions: Divide the mixture into greased muffin cups for convenient breakfast egg muffins. Adjust the baking time and check that the centers are fully set.
• Keep the eggs tender: Avoid overbaking. Remove the casserole once the center is set to prevent a dry, rubbery texture.
• Choose your sausage carefully: Use plain beef or turkey breakfast sausage without pork ingredients, and check the label for added ingredients.
