Egg bakes are the perfect meal prep
There’s no better meal prep for breakfast or lunch than an egg bake: they are simple to prepare, easy to cook (pop it in the oven and let it do it’s thing!), and store really well in the fridge for a few days. Better yet, they also freeze perfectly, if you don’t plan on eating the portions right away. I love stocking my freezer with portions of meal prepped breakfast or lunch ideas, so that on the weeks where I don’t have the time to cook from scratch, I have healthy options on hand. If you plan on freezing an egg bake, simply wrap individual serving sizes in plastic wrap or pop them into a freezer bag. To defrost, put a portion in the fridge overnight and then reheat in the morning. Or, simply microwave to defrost. Egg bakes reheat really well in the toaster oven, microwave, conventional oven, or air fryer! You can’t beat it.

- Traditional pesto sauce uses a lot of olive oil which tends to be high in calories, although since only 1/4 cup is used for this recipe, it’s perfect to use storebought here. My homemade skinny pesto sauce requires just six ingredients–with one special ingredient used to stretch the oil without compromising flavor or texture. There is minimal prep required–just break out your food processor or blender!

WOW! This recipe is soooo delicious. It was easy to make and works within my WW points. Thanks, Steph.
I meal prepped this egg bake on Sunday for our “meatless Monday” dinner. We had it last night and it was absolutely delicious! The flavoring of the pesto with the eggs, cheese and vegetables was perfect! My husband, who usually doesn’t like mushrooms, loved it and wants it for our Monday night dinners moving forward. It was so easy to prepare. Thanks, Steph for another winning recipe!!!
I made this for breakfast today, absolutely delicious and easy to make. So excited to have for breakfast again tomorrow! Thanks, Steph!
Wow! Brilliant recipe, tastes amazing, honestly not that difficult and now I’m ready to host brunch … or just hoard the entire casserole dish to myself for the week. Thanks for another amazing recipe steph! You’ve knocked this one outta the ballpark!
So delicious!! I made you pesto and that is amazing as well!!
I love love LOVE this recipe. It’s so easy + great for meal prep!
Made this last week for meal prep, sans mushrooms because they’re just not my thing, and loved the pesto aspect. Made it again this week with broccoli, onion, and grape tomatoes because that’s what I had left over in my fridge. Added two more eggs to get 6 good size pieces for the week. I love your recipes because they’re delicious, healthy, and accessible, but I also love that following you has given me, and absolutely awful cook, the courage to play with a recipe a bit using what I have on hand.
Excellent. My husband and I enjoyed this for brunch this morning. Such great flavors. Stephanie always makes each recipe so flavorful. Thank you for your recipes, I’ve made many of them.
This absolutely delicious!! The flavour combination is so good. Perfect breakfast for the week!
Made this for breakfast this week!! I love it!! thank you for a unique take on eggs!!
