This Mediterranean Frittata Slow Cooker Recipe is the hands-off brunch solution my family asks for every single weekend. I remember standing in my grandma’s farmhouse kitchen watching her whisk eggs by the dozen and realizing that the best meals do not need constant hovering.
While my Midwest roots usually lean toward hearty casseroles and Southern biscuits, I have always loved bringing a touch of the Mediterranean to our Sunday table. The sizzle of garlic and onions hitting a hot skillet followed by the salty scent of feta instantly takes me back to those cozy mornings where the stove was always warm and the coffee was always brewing. With this Mediterranean Frittata Slow Cooker Recipe, your kitchen is about to smell wonderful and you will not even have to tie on an apron until it is time to eat.
What Makes This Frittata So Special
Growing up, Sunday mornings meant big gatherings and even bigger appetites, so I learned early on how to feed a crowd without spending all morning at the stove. This slow cooker frittata does exactly that.
- Hands-off cooking leaves you free to enjoy your morning coffee and family
- Packed with accessible ingredients you likely have, like eggs, frozen spinach, and feta
- Delivers consistent, fluffy results every single time without the worry of a burnt bottom
- Adapts easily to whatever veggies you have leftover in the crisper drawer
- Creates that perfect balance of savory, salty, and slightly sweet when paired with fruit
Ingredient Spotlight
- Frozen chopped spinach: I always choose frozen for frittatas because it is already wilted down. Just make sure you squeeze it completely dry so your frittata does not get soggy.
- Feta cheese: In my kitchen, I prefer a block of feta that I crumble myself rather than pre-crumbled, as it gives a creamier, richer texture to the eggs.
- Kalamata olives: These add a briny, authentic Mediterranean punch that cuts through the richness of the eggs and cheese beautifully.
- Extra virgin olive oil: This is the foundation of your flavor, so use a good quality one to saute your vegetables properly.
- Red bell pepper: I love adding this for a pop of color and a subtle sweetness that balances the salty feta and olives.
From Start To Finish
Step 1. Betty always starts by coating the inside of her slow cooker with softened butter to ensure nothing sticks and it adds a lovely flavor.
Step 2. Heat your olive oil in a large skillet over medium-high heat.
Step 3. I have found that giving the chopped onion, sliced mushrooms, garlic, and dried basil a quick 2 to 3 minute saute builds a wonderful flavor base.
Step 4. Add your chopped red bell pepper and cook for another 4 to 5 minutes until all the vegetables are nice and tender.
Step 5. Stir in that thoroughly squeezed-dry spinach and cook for just 2 minutes to warm it through.
Step 6. The key I discovered is stirring the olives in right at the end before moving the whole vegetable mixture into your buttered slow cooker.
Step 7. In a large bowl, beat your eight eggs and mix in the crumbled feta, salt, and black pepper until well combined.
Step 8. Pour this egg mixture evenly right over the vegetables in your slow cooker.
Step 9. Place the lid on and cook on LOW for 2 1/2 to 3 hours or on HIGH for 1 1/2 to 2 hours.
Step 10. After years of making this, I know it is done when the center is completely set and does not jiggle when you gently tap the side of the slow cooker.
Making The Most Of Leftovers
I typically store leftover wedges in an airtight container in the refrigerator where they stay fresh for 3 to 4 days. Betty’s freezing method works well here too. Just wrap individual wedges tightly in plastic wrap and foil, and they will keep in the freezer for up to 2 months without losing flavor. For the best texture, I reheat by popping a wedge into the toaster oven or air fryer until it is heated through, which keeps the edges slightly crisp rather than rubbery like the microwave sometimes does.
Building The Perfect Plate
- Fresh strawberries: The sweetness perfectly balances the savory, salty feta
- Whole grain toast: Ideal for soaking up any leftover egg juices on your plate, like our perfect parmesan garlic bread (https://nonnafood.com/perfect-parmesan-garlic-bread-recipe/)
- Simple green salad: A light arugula salad with a lemon vinaigrette cuts through the richness of the dish
- Roasted vegetables: Our maple glazed carrots and brussels sprouts (https://nonnafood.com/maple-glazed-carrots-and-brussels-sprouts/) make a great hearty side for a diner-style breakfast plate

FAQs
Yes, just saute it with the other vegetables until completely wilted and drain any excess liquid well.
To prevent this issue, make sure your thawed frozen spinach is squeezed completely dry before adding it to the pan.
Many home cooks find success with assembling it in the slow cooker insert, covering it, and keeping it in the fridge overnight before turning the Crock-Pot on in the morning.
