Ingredients

• 8 large eggs
• 1 cup milk (whole or 2%)
• 1 cup shredded mozzarella cheese
• 1 cup shredded cheddar cheese
• 1/2 pound ground turkey sausage (or chicken sausage, ensure it’s seasoned and fully cooked)
• 1 small onion, diced
• 1 bell pepper, diced (any color)
• 1 cup fresh spinach, chopped
• 2 cups frozen hash browns, thawed
• 2 cloves garlic, minced
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1/2 teaspoon paprika (optional, for a little smoky flavor)
• Cooking spray or a little olive oil, for greasing the crock pot

How To Make Overnight Crock Pot Breakfast Casserole

Step 1: Prepare Your Crock Pot

Start by greasing the inside of your slow cooker with cooking spray or a light drizzle of olive oil. This will prevent the casserole from sticking and make cleanup easier.

Step 2: Cook the Sausage and Vegetables

In a skillet over medium heat, cook the ground turkey sausage until it’s browned and cooked through, about 5-7 minutes. Remove the sausage and set aside. In the same skillet, sauté the diced onion, bell pepper, and garlic until tender, about 3-4 minutes. Add the chopped spinach last, cooking just until wilted. Remove from heat.

Step 3: Combine the Egg Mixture

In a large bowl, whisk together the eggs, milk, salt, pepper, and paprika (if using) until well combined.

Step 4: Assemble the Casserole

Add the thawed hash browns to the bottom of the slow cooker. Layer the cooked sausage and sautéed vegetables evenly on top. Sprinkle the shredded mozzarella and cheddar cheeses over the mixture. Pour the egg mixture evenly over everything, allowing it to seep through the layers.

Step 5: Refrigerate Overnight

Cover the slow cooker with its lid and refrigerate overnight. This allows the flavors to meld and the eggs to soak into all the ingredients.

Step 6: Cook in the Morning

In the morning, set your slow cooker to low and cook the casserole for 6-8 hours, or on high for 3-4 hours. The casserole is done when the eggs are fully set and a knife inserted in the center comes out clean.

Step 7: Serve and Enjoy

Once cooked, switch off the slow cooker and let the casserole cool for a few minutes. Use a spatula to cut and serve warm. Garnish with fresh herbs like parsley or chives if desired.

Expert Tips

• Make sure the slow cooker insert fits your ingredients well; a 4 to 6-quart slow cooker works best.
• Use full-fat or 2% milk for a creamier texture. Non-dairy milk like almond or oat milk can be used but may alter the texture slightly.
• Don’t skip thawing the hash browns — this prevents excess moisture from making the casserole soggy.
• Layer ingredients evenly so the casserole cooks uniformly.
• If you like a crispier top, you can broil the cooked casserole in the oven for 2-3 minutes before serving.
• Use a toothpick or knife to check doneness; it should come out clean with no runny eggs.
• For best results, avoid opening the slow cooker frequently while cooking, as it releases heat and prolongs the cooking time.

Variations and Customizations

• Vegetarian Version: Skip the sausage and add extra vegetables like mushrooms, zucchini, or tomatoes. Add a bit more cheese or use a plant-based sausage alternative.
• Different Cheeses: Swap mozzarella and cheddar for feta, pepper jack, or gouda for unique flavor profiles.
• Spicy Kick: Add diced jalapeños or a dash of hot sauce to the egg mixture for some heat.
• Herb Infusion: Mix in fresh herbs such as basil, thyme, or oregano for a fragrant touch.
• Gluten-Free: This recipe is naturally gluten-free, but always check labels on processed ingredients to be sure.
• Make it Dairy-Free: Use dairy-free cheese alternatives and substitute milk with coconut or almond milk.
• Protein Boost: Add cooked chicken, turkey bacon, or even chickpeas for extra protein variety.

How to Store Leftovers

Store any leftover casserole in an airtight container in the refrigerator for up to 3-4 days. Reheat portions in the microwave for 1-2 minutes or until warmed through. You can also freeze leftovers by wrapping individual portions in plastic wrap and placing them in a freezer-safe container or bag for up to 2 months. Thaw overnight in the fridge before reheating.

FAQ

Can I use a different type of sausage?

Absolutely! You can substitute the ground turkey sausage with chicken sausage, beef sausage, or even a vegetarian sausage alternative. Just ensure it’s fully cooked before adding it to the casserole.

Do I have to soak the casserole overnight?

Soaking overnight helps the eggs absorb the flavors and results in a better texture. However, if you’re short on time, you can assemble it in the morning and cook it immediately, though the flavor and texture might not be as rich.

Can I use fresh potatoes instead of hash browns?

Yes, but you should cook and dice the potatoes first, then allow them to cool before adding. Raw potatoes may take longer to cook and could affect the final consistency.

What if I don’t have a slow cooker?

You can bake this casserole in the oven at 350°F (175°C) for about 45-55 minutes, or until the eggs are set. Use a greased baking dish and cover with foil for the first 30 minutes to prevent over-browning.
