Make
- Heat oven to 425F / 218C.
- While oven is heating, heat a 10.5” to 12” (26 cm to 30 cm) oven-safe skillet over medium-high heat. (Note: skillet size is for 4 servings. If customizing, use a larger or smaller skillet, or you can transfer the cooked filling to a muffin tin and top it with the egg mixture before baking.)
- To heated skillet add cooking oil and then onions to heated oil. Saute until tender, 3 to 5 minutes.
- Add mushrooms and saute until very tender and golden brown, 6 to 8 minutes. Season with some salt.
- Stir in spinach leaves until slightly wilted, 3 to 4 minutes more.
- Pour egg mixture over vegetables and stir to combine.
- Crumble feta over top.
- Transfer skillet to oven and bake for 20 to 25 minutes. (Frittata is done when eggs are set and a knife inserted in the center comes out clean.)
- Just before serving, toss greens with dressing.
- Slice frittata and serve with salad. Enjoy!

Put it on only 200C and for under 15 minutes, if I’d put it on higher and longer it would’ve been completely burnt, or at least cork dry. Kinda tasty but not my favourite.

The frittita was great but I wasn't keen on the salad dressing. We had it with oven chips, which worked well.
0 HelpfulThis was good. Did it in a muffin tin so I could keep the mushrooms out of mine and put in tomatoes instead. Probably would have been better if we had silicone cups - putting the veggies in and then adding the eggs made the liner pretty soggy. But everyone liked it and the kids loved getting them as individual servings. Also added about 1/4 cup of Asiago cheese to egg mix because we had some I wanted to use up.
0 HelpfulDelicious! I made the original as meal prep for my breakfasts for the week. Easy to make, and great warmed up again!
