This Cheese and Spinach Mini Frittata recipe is easy to make, and the perfect bite-sized dish for breakfast or brunch!
I've always loved brunch, long before brunching became an adverb.
Brunch and Mother's Day have almost become synonymous. I like the idea of a Mother's Day wine tasting, or a Mother's Day hike. But I really LOVE a nice leisurely brunch at home. It's a great way to celebrate Mother's Day, Easter, or any spring weekend morning.
If you're looking for a delicious breakfast or brunch recipe, you can't go wrong with my popular, 5-star rated Banana Crumb Coffee Cake. Or, with almost any egg dish.
While I love making full size quiches - like this bacon mushroom quiche or this ham and spinach quiche - mini frittatas are sometimes just what you need. They're also the perfect healthy breakfast for busy mornings!

These are very tasty ... but how do you keep them from going flat? Mine looked more like mini pancakes vs muffins. Still delicious but curious if there is a trick to keep them from going flat?
Marlynn Jayme Schotland says
Hi Lisa! Frittatas are always going to deflat a little bit when you take them out of the oven, but mine have never turned out flat before. Since every oven heats up a little differently, if you find that yours come out flat, try taking them out of the oven a minute or two earlier (make sure the eggs aren't runny!), then allow them to rest at room temperature before removing them from the pan. If you try that next time let me know how it goes!
Terri says
Can these be frozen and reheated later? If so, do you let them thaw and then reheat or heat frozen? I'm thinking this is a great option for my hubby to take to work for breakfast. Thank you!
Marlynn Jayme Schotland says
Terri - yes, these can be cooked, cooled to room temp, frozen, and then heated up before serving. I usually take them out of the freezer, preheat the oven, and then by the time the oven is preheated, they are ready to be heated up. If you're reheating in the microwave, I'd let them thaw out a bit from frozen before microwaving them.
Sheena says
These are delicious!! And super easy to make. Made them for Christmas Brunch and they were a hit. Only problem, there weren’t enough. Double the recipe for happy customers!
Sandy Viveiros says
Making these Mini Cheesy Spinach Frittatas for a Baby Shower Brunch in a couple weeks. Would like to make ahead and freeze, if I do that do they need to be thawed before reheating or can they go from freezer to oven, and if so, how long?
Thank you in advance!

Do you have to use almond milk?
