Equipment You’ll Need for This Slow Cooker Breakfast Casserole

This recipe requires a standard 6-quart slow cooker (or Crockpot). Make sure yours has a tight-fitting lid to keep the steam locked in for even cooking. I also recommend slow cooker liners for incredibly easy clean-up—because who wants to scrub dishes early in the morning?

Don’t have a slow cooker yet? Any basic model with a “High” and “Low” setting will do. Just set it to the appropriate heat, and you’re golden.

Simple Ingredients for Slow Cooker Breakfast Casserole

This dish is built on a handful of accessible and affordable ingredients, which is why it’s a hit in my house. Here are the MVPs:

• Hash Browns: I use Simply Potatoes Shredded Hash Browns for convenience—no peeling or shredding required! You can also swap in frozen hash browns (just thaw them first).
• Turkey Sausage: Lean and packed with flavor. You can substitute with pork sausage or even plant-based sausage crumbles if preferred.
• Eggs: The heart of the casserole. Whisked with milk, they create that fluffy, satisfying texture.
• Cheddar Cheese: A classic choice! Feel free to experiment with other cheeses like Monterey Jack or a shredded Mexican blend.

How to Make Slow Cooker Breakfast Casserole

4. Whisk the eggs: In a large mixing bowl, whisk together the eggs and milk. Season with a pinch of salt and pepper.
5. Assemble the casserole: Pour the egg mixture over the hash browns and sausage. Top with shredded cheddar cheese.
6. Cook: Cover the slow cooker and set it to HIGH for 3-4 hours, or LOW for 7-8 hours, until the eggs are set and the cheese is melted.

Jake’s Tips for the Best Slow Cooker Breakfast Casserole

• Precook for Speed: Using pre-browned sausage will shave 10 minutes off your prep time.
• Layer Wisely: Always add the hash browns as the base—they soak up the egg mixture beautifully without getting soggy.
• Adjust Cheese: Want it extra cheesy? Add a layer of cheese halfway through cooking.
• Test for Doneness: Insert a butter knife in the center—if it comes out clean, your casserole is ready!
• Make Ahead: Prepare the night before, refrigerate, and just cook when ready in the morning.

Easy Slow Cooker Breakfast Casserole Variations

• Vegetarian Style: Swap the sausage for sautéed mushrooms, spinach, and bell peppers.
• Spicy Kick: Add diced jalapeños or use spicy cheddar cheese.
• Southwestern Flair: Mix in black beans, corn, and a sprinkle of taco seasoning.
• Clean-Out-the-Fridge: Use leftover roasted vegetables or deli meat for a creative twist.

Slow Cooker Breakfast Casserole FAQs

Can I use frozen hash browns?

Yes, you can use frozen hash browns. Just make sure to thaw them completely and pat them dry to remove excess moisture before layering.

What type of sausage works best?

I prefer lean turkey sausage for a lighter option, but pork sausage or even plant-based crumbles work just as well.

Can I make this casserole ahead?

Absolutely! Assemble it the night before, store it in the fridge, and start cooking it first thing in the morning.

How do I store leftovers?

Store leftover casserole in an airtight container in the fridge for up to 3 days. Reheat individual servings in the microwave for a quick breakfast.

Can I double the recipe?

This recipe fits perfectly in a standard 6-quart slow cooker. If doubling, use an 8-quart slow cooker to avoid overflow.
