Sausage & Egg Keto Breakfast Casserole

This keto breakfast casserole is perfect for meal prep, weekend brunch, and holiday breakfasts. With eggs, cheddar cheese, sausage, and spinach, this nutritious dish is gluten free and ultra low carb, with only 1g net carb per serving.

What Makes This Recipe So Good

• This casserole is SO easy to make fresh, but it’s also totally perfect for meal prep and make-ahead meals. For meal prep, fully bake the casserole ahead of time, refrigerate in an airtight container, and reheat servings in the microwave. For a make-ahead option, prepare everything right up to the point of baking and cover the dish securely with plastic wrap or a lid. Refrigerate it overnight and pop it straight into the oven 30 minutes before you’re ready to eat.
• It’s full of nutritious ingredients – whole eggs, fresh spinach, breakfast sausage without added sugars. Since it’s keto-friendly, low carb, and gluten free, it’s a recipe that just about everyone can enjoy.
• If you prefer a breakfast casserole with bacon instead of sausage, you can totally do that here! This recipe is honestly pretty versatile. Add onions and peppers if your keto is a little looser. Include steamed or riced cauliflower if you’re really missing a classic tater tot casserole. Use half and half instead of heavy cream if you’d like a little less fat. Change up the cheese you use and the spices. Use bacon and sausage for a meat lovers’ casserole.

Chef’s Tips

• The heavy cream is what keeps your eggs tender and fluffy, so don’t skip it. If you leave it out entirely, your eggs will likely end up tough and rubbery. Milk or half and half will work in its place, to a lesser degree, and coconut cream will work if you need a paleo or dairy-free option (make sure you switch out the cheese, too!).
• Make sure you use a 9×13 baking or casserole dish. If you use a smaller pan, you’ll likely end up with undercooked eggs after 25 minutes in the oven. Glass or ceramic will both work fine, just make sure your dish is large enough.
• If you prefer sautéed spinach, toss your spinach leaves in the skillet with the sausage right before the sausage is ready. Cook the spinach down as you like it, then layer it in the baking dish with the sausage. Just keep in mind that spinach cooks down A LOT when it’s sautéed, so 3 cups sautéed may not have as much presence in your casserole.

Equipment

• 9×13 baking dish
• cooking spray or butter, to grease baking dish
• Large skillet
• spatula or wooden spoon
• Large mixing bowl
• whisk

Instructions 

• Preheat oven to 375° Fahrenheit. Lightly grease baking dish, then layer spinach leaves, white parts of scallions, and chopped parsley in bottom of baking dish. Set dish aside.
• In large skillet over medium heat, cook breakfast sausage until browned and crumbled. Stir often while cooking and break sausage into small pieces with spatula or wooden spoon.
  
• While sausage cooks, whisk together eggs, heavy cream, garlic powder, salt, and pepper in large mixing bowl. Once ingredients are fully combined, gently fold in shredded cheddar cheese.
  
• Layer cooked sausage on top of spinach leaves in baking dish. Pour egg mixture over sausage, making sure to distribute mixture as evenly as possible across baking dish.
  
• Place baking dish in preheated oven and bake 20 to 25 minutes or until casserole is firm and eggs are cooked through. Remove from oven and slice into 12 squares. Garnish with green parts of scallions and additional shredded cheese if desired, then serve warm.
  

Notes

• Sausage: Feel free to use hot or mild pork, turkey, or chicken breakfast sausage to fit your tastes and preferences. Just make sure your sausage doesn’t contain any added sugar or sugar alternatives.
• Cheese: For best results, shred your own cheddar cheese from a block. Prepackaged shredded cheese contains fillers and starches to prevent clumping, which add unnecessary carbs and keep the cheese from melting well.
