I love a good Slow Cooker Breakfast because it means I don’t have to stand over the stove while my kids demand snacks (before breakfast is even done cooking). This Slow Cooker Quiche is packed with protein, totally customizable, and basically foolproof. Plus, it gives off major The Magical Slow Cooker energy—like, it looks fancy, but in reality? It’s the easiest thing ever.

If you’ve been looking for a Crock Pot Breakfast that actually fits into real-life chaos (ahem, everyday breakfast), this is it. Let’s get into this Egg Quiche Recipe that’ll make your morning routine just a little easier.
What You’ll Need
The Basics:
- 6 large eggs (because eggs = protein, and protein = full bellies)
- 1 cup milk (whole or 2% works best, but honestly, use what you have)
- ½ cup heavy cream (makes it extra fluffy, but you can use more milk if needed)
- 1 cup shredded cheese (cheddar, Swiss, or literally whatever is about to expire in your fridge)
- ½ teaspoon salt
- ¼ teaspoon black pepper
The Add-Ins (A.K.A. What’s In Your Fridge?):
- ½ cup diced bell peppers
- ½ cup chopped spinach (for when I’m pretending to be a healthy mom)
- ¼ cup diced onions
- ½ teaspoon garlic powder
- 1 teaspoon Italian seasoning (optional, but makes you feel like a fancy chef)
Step-by-Step: How to Make Crockpot Quiche
Step 1: Grease That Crockpot
Spray the inside of your slow cooker with cooking spray or rub it down with butter. If you forget this step, you will regret it when you’re scraping eggs off the sides later.
Step 2: Whisk Everything Together

In a big bowl, beat the eggs, milk, and heavy cream until they’re nice and smooth. Stir in the salt, pepper, and any extra seasonings.
Step 3: Layer the Good Stuff
Dump your cheese and add-ins (veggies, etc.) into the crockpot. Spread them out evenly so every bite gets some goodness.
Step 4: Pour in the Egg Mixture
Slowly pour your egg mixture over everything. Give the crockpot a little shake to make sure it settles evenly.
Step 5: Let the Crockpot Do Its Magic
- Low for 4-5 hours OR High for 2-3 hours
- You’ll know it’s done when the center is set and a knife stuck in the middle comes out clean.
Step 6: Let It Rest (Yes, Really)
I know, I know. Everyone is hungry. But let the quiche sit for at least 10 minutes before slicing. This helps it firm up so it doesn’t fall apart when you serve it.
FAQs About Crockpot Quiche
Can I make this Crockpot Quiche overnight?
Technically, yes—but I don’t recommend it unless you want rubbery eggs. Slow cookers can vary, and even on low, 6+ hours is pushing it for eggs. If you really need it ready first thing, try using a smart plug or a slow cooker with a timer to start cooking early in the morning.
Can I use just egg whites?
Yep! Swap out the 6 whole eggs for about 10 egg whites. Just keep in mind, that using only egg whites makes it less rich and fluffy, so consider adding an extra splash of cream or cheese to help with texture.
Can I double the recipe?
If you have a big slow cooker (6-7 quarts), you can double the ingredients! Just add an extra 30-60 minutes of cook time and check for doneness.
Can I make this dairy-free?
Yep! Use unsweetened almond, oat, or soy milk and skip the cheese (or use a dairy-free cheese). The texture won’t be as creamy, but it’ll still work!
Can I cook this on high instead of low?
Yes! Cook on high for 2-3 hours instead of low for 4-5. Just check it early, because slow cookers can vary.
Is this good for meal prep?
100%! Make it at the beginning of the week, cut it into slices, and store them in the fridge for easy grab-and-go breakfasts.
